Coating classification: nitrocellulose paint

Core tip: nitrocellulose paint is a common coating for woodwork and decoration Nitrocellulose is the main film-forming material of nitrolacquer, which is composed of alkyd resin, modified rosin resin, acrylic resin, amino resin and other soft and hard resins Chinese name nitrolacquer Main film-forming material nitrocellulose Application of wood and furniture painting Decoration coating, metal coating, etc brief introduction Nitrocellulose paint is a common coating for woodwork and decoration Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: nitrocellulose paint, is more common wood and decoration coatings Nitrocellulose is the main film-forming material of nitrolacquer, which is composed of alkyd resin, modified rosin resin, acrylic resin, amino resin and other soft and hard resins Nitrocellulose paint is one of the most common coatings for wood and furniture decoration, metal coating and so on Nitrocellulose is the main film-forming material of nitrolacquer, which is composed of alkyd resin, modified rosin resin, acrylic resin, amino resin and other soft and hard resins Generally, dibutyl phthalate, dioctyl ester, oxidized castor oil and other plasticizers should also be added The main solvents are esters, ketones, alcohol ethers and other real solvents, alcohol and other cosolvents, and benzene and other diluents Nitrocellulose paint is mainly used for painting wood and furniture, home decoration, general decoration coating, metal coating, general cement coating, etc It has been more than 100 years since the appearance of nitrolacquer China began to produce and apply nitrolacquer in 1935 The production of nitrolacquer in the United States reached 42.3 million gallons (160 million liters) Nitrocellulose paint is very popular because of its fast drying, good decoration and good outdoor weather resistance It can be polished, polished and polished to modify the defects caused by paint film during construction At that time, only nitrocellulose paint can be sprayed, which is suitable for large-scale construction DuPont products have been used in the world's first automobile body coating line After the 1950s, with the development of the technical force of the coating industry, domestic coating enterprises have the conditions to improve the old products, develop new products, adopt new processes and add new equipment, so that the production quality of nitrolacquer is improved, the variety is increased, and the development is relatively rapid At that time, the main products were nitro primer and putty, nitro industrial paint (internal nitro enamel), automobile paint (external nitro paint), wood paint, pencil paint, leather paint, plastic paint, etc Before the 1970s, it was a high-grade coating product with good decoration, and its output increased year by year By the mid-1980s, after the statistics of 18 categories of coating products in China, the ratio of its output to the total coating output was relatively stable With the development of coating industry, the progress of science and technology, in order to meet the needs of society, a batch of new products have been developed successfully, many synthetic resin coatings have emerged In order to make the coating products meet the requirements of the national industrial construction, the original Ministry of chemical industry proposed in the optimization and adjustment scheme of product structure: "limit the first four categories (grease paint, natural resin paint, phenolic paint, asphalt paint), transform the two categories, namely, nitro paint and perchloroethylene paint, so as to further improve their quality and develop synthetic resin paint" The development of synthetic resin paint has also squeezed out the market of nitrocellulose paint For example, in the early 1960s, Beijing paint factory, the predecessor of Beijing Hongshi paint company, cooperated with Beijing automobile repair factory It was the first one in China to change the nitrocellulose paint used by trolleybuses and buses in Beijing to amino alkyd baking paint The decoration quality and weather resistance have been significantly improved, greatly extending the maintenance time of these vehicles It has the advantages of good decoration, simple construction, rapid drying, low requirements for painting environment, good hardness and brightness, no film defects and easy repair The disadvantage is that the solid content is low, and more construction passes are needed to achieve better results; the durability is not good, especially the internal nitro paint, which has poor light and color retention, and is prone to defects such as loss of light, cracking, discoloration and so on if it is used for a little longer time; the protective effect of the paint film is not good, and it is not resistant to organic solvents, heat and corrosion Classification nitrocellulose paint can be divided into four categories: external varnish, internal varnish, wood varnish and various enamel (1) Nitrocellulose varnish for external use: it is composed of nitrocellulose, alkyd resin, flexible agent and some ester, alcohol and benzene solvents, with good gloss and durability of the film, which can be used for outdoor metal and wood surface finishing (2) Nitrocellulose varnish for internal use: it is composed of low viscosity nitrocellulose, glycerin rosin ester, non drying oleic acid resin, flexible agent and a small amount of ester, alcohol and benzene organic solvents The coating film is fast drying, bright and poor outdoor weather resistance It can be used for indoor metal and wood surface coating (3) Nitrocellulose wood varnish: it is made of nitrocellulose, alkyd resin, modified rosin, pliable agent and appropriate amount of ester, alcohol and benzene organic volatile The coating is hard and bright, and can be polished, but it has poor weather resistance It can only be used for indoor wood surface finishing [1] (4) various colors of nitroalkyd enamel: it is made of nitrocotton, pentaerythritol resin, pigment, flexible agent and appropriate solvent The coating film is dry, smooth, flat and has good weather resistance, but poor wear resistance It is suitable for indoor and outdoor metal and wood surface coating [1] The composition is made of nitrocellulose, alkyd resin, pigment, plasticizer and organic solvent The characteristics of the paint film are fast drying, smooth, bright and weather resistant, shorten the construction period, and improve the production efficiency It is suitable for the protection and decoration of machine tools, equipment and tools It is required that there is no hard block in the project indicator vessel after state mixing, and the fineness is uniform, um ≤ 20, two layers of construction spraying, barrier free drying schedule, dry min ≤ 20, dry h ≤ 4, paint film color and appearance, paint film is flat and smooth, meeting the standard template and its color difference range, flexibility, mm ≤ 3, adhesion (level) ≤ 2, construction 1 Mix the paint well before use If there are paint particles or impurities, they must be filtered and removed 2 Use nitro diluent, adjust construction viscosity, mainly air spraying 3 The coated surface shall be thoroughly cleaned before construction 4 When the air humidity is high, the paint film tends to turn white, so nitro moistureproof agent should be added to adjust the viscosity of the paint 5 The construction time should be about 10min 6 Matching primer: nitro primer, perchloroethylene primer 1 During transportation, the products shall be protected from rain, sunlight and collision, and shall comply with the relevant regulations of the transportation department 2 The product shall be stored in a cool and ventilated place to prevent direct sunlight, isolate the fire source and keep away from the heat source Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
