popular architectural coating, which is one of the development directions of architectural coatings Because of its elegant, fresh decoration effect, non-toxic, tasteless environmental characteristics, the proportion of architectural coatings is increasing, and gradually in line with international standards China's architectural coatings are in the transition from low-grade products to medium and high-grade products, in which the rise and development of latex coatings are indispensable The research and development of latex paint in China began in the 1960s, and its real development was in the late 1970s, when it began to be widely used in the interior wall, exterior wall, ceiling and other parts of the building In the past ten years, latex coatings have made great progress in terms of product variety, product level, production capacity, construction machinery and application Especially in recent years, the influx of high-quality products from abroad, together with the propaganda of some large companies, has greatly improved the popularity of latex coatings and promoted the development of latex coatings 1 An overview: latex paint, commonly known as latex paint, the official name is synthetic resin emulsion paint, is based on synthetic resin emulsion, adding pigments, fillers and various auxiliaries made of a class of waterborne coatings Only when its composition is clear can we distinguish the true and false products in the market At present, there is a kind of low price (the price is only 2-3 yuan / kg) in the construction paint market, but it is named "advanced latex", "economic latex paint" and so on The sales momentum is good In fact, the products are polyvinyl alcohol or even starch and other water-soluble resins as the main film-forming materials Without adding or adding only a small amount of emulsion, they will be labeled with latex paint, which is a fake and shoddy product, causing confusion to the market This article does not cover such coatings 2、 Characteristics of latex coating: 1 Latex coating is a kind of environmental protection product, which takes water as dispersion medium, does not pollute the environment, is safe, non-toxic and has no fire hazard 2 The construction is convenient Consumers can brush or roll the construction by themselves, and the construction tools can be cleaned with water 3 Fast drying of coating and short construction period Under suitable climatic conditions, coating construction can sometimes be completed on the same day 4 It has a good decorative quality, with a variety of colors and luster (matte, matte, semi gloss) to choose from The decoration is fresh and elegant For example, in recent years, the more popular silk emulsion paint, with silk matt coating, smooth and delicate feel like silk, can create a warm atmosphere for the room 5 In terms of maintenance, if you want to change the color, you only need to make a little treatment on the original coating, and then you can apply the refreshed emulsion paint In developed countries in Europe and America, it has become a family pleasure to paint latex paint by yourself to change the color of houses Although the decoration of latex paint is not as luxurious and magnificent as that of wallpaper, wooden wainscot, wooden veneer and upholstery, it is more suitable for the comfortable and warm needs of home decoration Therefore, latex coating is an ideal material for the decoration of the wall 3、 Difference of different products: at present, the market competition of architectural coatings in China is fierce Foreign latex coating products have entered China one after another Foreign investors not only bring advanced technology, but also bring rich marketing experience This is not a small impact on the domestic market, but also promote the level of domestic latex coating What are the differences between domestic and foreign latex coating products? One of the outstanding advantages of foreign products is the "open tank effect" After opening the package, it gives a good impression that the appearance is delicate, plump, similar to paint, with high and even viscosity and good fluidity; the other advantage is good construction, large painting area per square meter, strong covering power, flat film without brush marks, soft color and good overall decoration effect Domestic latex paint products, from the choice of synthetic resin emulsion and its coating properties, be roughly the same as foreign products Some properties are better than foreign products, such as water resistance and pollution resistance However, there is still a big gap in "opening effect", constructability and coating appearance After opening the package, it often appears the phenomenon of thinning up and thickening down, some even have water separation, and there is soft sediment at the bottom, which can only be uniform through mixing Some products pay attention to thickening from the appearance, but it affects the fluidity, poor workability, serious paint brush marks, soft color and poor fullness Only when we see the gap can we improve the quality At present, some domestic manufacturers have used foreign additives and other raw materials to solve the above problems, and some manufacturers' latex coating products have been comparable with foreign products Not only the physical properties of the product meet or exceed the national standards, but also the construction performance has made a qualitative leap The coating is smooth and has few brush marks, and the color is soft In addition, compared with foreign products, it has a great advantage in price and has a bright future 4、 Judgment and identification methods of latex coating: 1 Good opening effect, no water separation, no starch, no rust, no mildew 2 The construction effect is good, no brush mark and roller mark, the unit painting area is large, and the covering power is good Covering power refers to the minimum amount of coating evenly applied on the wall surface so that its background color no longer appears, expressed in grams per square meter The smaller the value is, the better, indicating that the unit area consumption is less In the original national standard GB9756-88 "synthetic resin emulsion interior wall coating", the standard is less than 250 grams / square meter, and this index can be used to calculate the amount of paint needed to be washed 3 The coating does not remove powder and can be scrubbed with water if it is dirty This requires that the coating has certain resistance to washing In the national standard GB9756-95 "synthetic resin emulsion interior wall coating", it is stipulated that the qualified product is not less than 100 times, and the first grade product is not less than 300 times Some products have no change in the washability up to 2000 times Some products have only a few washings, and the coating is damaged 4 The color of the coating is soft and does not blossom The judgment of latex coating should be based on the comprehensive analysis and comment of various properties, not only on a certain property The choice of latex coating should be based on the use, orientation, size and decoration budget of the room to be decorated Attention should be paid to the following problems when selecting latex coating: A try to select famous brand or brand products, and the products of the same kind with national environmental protection product mark should be preferred The production enterprises of these products have large scale, high output, strict management and guaranteed product quality B The packaging barrel of latex coating shall be provided with trademark, manufacturer's name, production date, weight and other important marks and data C It's better to buy in building materials mall or exclusive shop These businesses pay more attention to purchase channels and commodity reputation, and the product quality is more guaranteed Don't be greedy for cheap Buy cheap products in some grocery stores D, check whether emulsion paint has moldy, rust, serious water separation or special odor 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,
