people may think painting is just a common process, while others may think it is a creative process In any case, as long as you use the right materials, give some time, and keep a little patience, painting is easy In this article, we will discuss how to choose the best finish for your furniture wood In addition, we will explore some finishing techniques (including preparation and drying techniques) In this way, no matter what kind of finish you choose, furniture can keep its original appearance for a long time Generally, wood paint can be divided into two categories: water-based paint and oil-based paint (referred to as paint) Of course, there are other categories, such as primer and finish paint according to the level of use; highlight, semi matte and matte according to the luster; furniture paint and floor paint according to their uses; According to the properties, it can be divided into single component, two component and three component (1) waterborne lacquer is the first kind of waterborne wood paint with acrylic acid as the main component Acrylic emulsion is used as the main ingredient It is suitable for waterborne wood primer and matt finish The main features of the product are good adhesion, not to deepen the color of wood, but poor wear resistance and chemical resistance Due to poor gloss, it is unable to make high gloss paint, and the hardness is general, poor film-forming performance Because of its low cost and low technology content, it has become an entry-level product in the market The second type is water-based wood paint, which is mainly composed of acrylic acid and polyurethane In addition to adhering to the characteristics of acrylic paint, it also increases the characteristics of wear resistance and chemical resistance (the first two types are mostly used for doors and windows, furniture) It has the advantages of both the above two kinds, and the cost is relatively moderate It can be self crosslinked or used in two-component system, with good hardness, fast drying, wear resistance, good chemical resistance, low yellowing degree or unchanged yellow It is suitable for bright matt paint, primer, outdoor paint, etc The third type is 100% polyurethane waterborne wood paint, which is the high-grade product in the waterborne paint It includes aromatic and aliphatic polyurethane dispersions The waterborne wood paint with aliphatic polyurethane dispersions as the main component has excellent yellowing resistance and is more suitable for outdoor use They have good film-forming properties, high self crosslinking luster, good wear resistance, and are not easy to produce bubbles and shrinkage cavities However, the hardness is general and the price is expensive, which is suitable for making bright finish, floor paint, etc.; the fourth type is the water-based wood paint with the main component of water-based two-component polyurethane, one of which is the polyurethane water-based dispersion with - Oh, the other is the water-based curing agent, mainly aliphatic; The two components can produce cross-linking reaction through mixing construction, which can significantly improve the water resistance, hardness, film fullness and glossiness of the water-based wood paint, with good comprehensive performance and high yellowing resistance, especially suitable for outdoor painting However, the product is more complex in construction, which needs professional guidance 2 Advantages and disadvantages of water-based paint a, water-soluble paint, non-toxic environmental protection, no benzene and other harmful solvents, no free TDI B The construction is simple and convenient, it is not easy to have common defects of oil paint such as bubbles and particles, and the film feels good C High solid content, full film D No yellowing, good water resistance, no burning F It can be applied together with other paints such as emulsion paint G some water-based paints have low hardness and are easy to get scratches, which should be paid special attention during selection Generally speaking, water-based paint is a good choice in terms of construction and environmental protection, in addition to its slightly higher price （2） Paint 1 Paint classification: at present, there are more than 1000 kinds of paints on the market, with various designs and colors, and different names However, according to the composition properties, the commonly used paints are divided into the following categories: A large paint, also known as natural paint, which is divided into raw paint and mature paint Raw lacquer is toxic and its film is rough It is rarely used directly After being processed and modified, it can be made into various refined paints The paint is suitable for drying in humid environment The film has good luster, tenacity, high stability, strong acid resistance, but slow drying The modified quick drying push Polish paint and Tizhuang paint have low toxicity, tough paint film, can be sprayed and brushed, convenient construction, acid and water resistance, and are suitable for advanced coating B Clear oil, also known as cooked oil and paint mixing oil It can be used as the oil used in the mixing of raw paint and antirust paint, and can also be used alone Some clear oil (thin and thick paint and red lead) can be applied separately to wood or metal for rust prevention and corrosion protection Add a proper amount of pigment to make a colored clear oil C Thick paint, also known as lead oil It is a mixture of pigment and earth oil It can only be used after being diluted by oil and solvent It is widely used in the primer of surface layer and can also be used as surface coating alone It is suitable for the filling materials of buildings with low requirements, wood primer and water pipe joints D mixed paint, also known as mixed paint It is the most commonly used paint The texture is soft, uniform, moderate, corrosion-resistant, sun resistant, long-term crack free, strong covering power, good durability, and convenient for construction It is divided into two kinds of oil ready mixed paint and magnetic ready mixed paint This kind of mixed paint is better than oil mixed paint The film is hard, bright and smooth, but the weather resistance is worse than oil mixed paint E Varnish and varnish can be divided into oil-based varnish and resin varnish The former is commonly known as "fanlishui" and the latter as "bubble Lishui" It is a transparent paint without pigment Resin used in resin varnish are polyester resin, polyurethane, acrylic resin, etc Varnish has the following kinds: ● ester gum varnish, also known as water-resistant varnish The paint film is bright and water resistant, but the gloss is not durable and the dryness is poor It is suitable for painting wooden furniture, doors and windows, board walls and covering metal surfaces ● phenolic varnish, commonly known as Yongming paint Fast drying, tough and durable paint film, good gloss, heat resistance, water resistance, weak acid and alkali resistance, the disadvantage is that the paint film is easy to turn yellow and brittle It is suitable for the painting of wooden furniture doors and windows, board walls and the covering of metal surfaces ● alkyd varnish, also known as Sanbao paint This kind of paint has better adhesion, glossiness and durability than the first two It is fast drying, high hardness, can be polished, polished, bright color But the film is brittle, heat-resistant and atmospheric resistant Suitable for painting indoor doors and windows, ground, furniture, etc ● nitrocellulose varnish, also known as lacquer, lac It has the characteristics of fast drying, hard, bright, wear-resistant and durable It is a high-grade coating, suitable for the coating and decoration of wood and metal surfaces, and used for high-grade doors and windows, board walls and handrails Shellac varnish, also known as bubble standing water, alcohol standing water, also referred to as paint chips It is a solution made by dissolving shellac tablets in alcohol above 95 degrees This kind of paint is easy to use, fast drying, hard and bright paint film The disadvantages are poor water resistance and weather resistance, sunlight exposure will lose light, hot water immersion will turn white It is generally used for the finishing of indoor wood furniture ● acrylic varnish It can be dried at room temperature, with good weather resistance, light resistance, heat resistance, mildew resistance and adhesion, but poor gasoline resistance Suitable for spraying anodized aluminum alloy surface It can be used as sealing agent in wood finishing The paint film is hard and bright It can be insulated It can dry quickly It is easy to turn white in case of hot water It has good adhesion It is mainly suitable for woodwork, furniture, etc Objects susceptible to moisture and heat are not suitable F Enamel is made of varnish and pigment After drying, the coating is magneto-optical and hard There are two kinds of commonly used enamel, phenolic enamel and alkyd enamel, which are suitable for metal window screen mesh, etc The antirust paint has zinc yellow and iron red epoxy resin primer The paint film is tough and durable, with good adhesion If it is used together with ethylene phosphating primer, it can improve the heat resistance and salt fog resistance It is suitable for bottoming of metal materials in coastal areas and warm tropics Home decoration, the most commonly used is polyurethane wood paint, and door and window alkyd enamel, alkyd mixed paint Polyurethane wood paint contains toluidine diisocyanate, which is a kind of harmful substance It has the function of tear, and also can make the skin slightly pigmented Its steam will have a strong stimulation on the respiratory tract Even under the low concentration of steam, 2-5% of people will have an allergic reaction similar to allergic asthma Organic solvents such as turpentine, turpentine water, gasoline, acetone, ether, etc used for alcohol grease and alkyd paint smell bad, even smoke people hard Some fake and inferior products replace alkyd resin with polyester waste silk, and use super strong solvent and pure benzene, the consequences are even more serious Pay special attention to the selection of high-quality products when using The room should be well ventilated after painting It is better to leave it vacant for 1-2 months after the decoration of the new house After ventilation, you can move in G The super environmental protection plant type paint has come into being The natural plant type paint coating is different from the coating from raw material selection to processing and manufacturing Its raw materials are selected from more than ten kinds of natural plants, such as linseed oil, orange oil, parasol oil, hemp resin, rosin, loquat oil, etc it is a new paint coating synthesized with high and new technology conforming to the natural ecological balance Just like tung oil, which has been used to make lacquerware since ancient times, natural plant type paint can be applied on the top of the wall and the surface of furniture When it is applied and evaporated after application, it will not cause any harm to human body Because the pigment and diluent solvent of the natural plant paint are also extracted from the natural plant, so there is no volatile harmful gas, so the staff can work in the closed space environment, and can enter after brushing Even if the residual material is constantly volatilized, it can return to the natural circulation In addition, various components from plants have affinity with the natural ecological environment, so that when painting, the construction personnel can smell a smell of orange or pine leaves, which makes people feel clear
