    Core tip: basic understanding of paint has been deeply rooted in the hearts of consumers, and has become a very common thing Many consumers still know little about paint, including some bosses who have been selling paint for more than ten years The paint can only be moved in one month after brushing Consumers think that the paint will not be toxic at this time In fact, this is wrong There is no pungent smell, but formaldehyde volatilizes to a level acceptable to human physiology The benzene, toluene and free TDI contained in paint curing agent and diluent are still volatilizing It will take at least decades for these things to volatilize completely And this Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Paint Home News: basic understanding of paint has been deeply rooted in the hearts of consumers, and has become a very common thing Many consumers still know little about paint, including some bosses who have sold paint for more than ten years who do not know the harm of paint very well The paint can only be moved in one month after brushing Consumers think that the paint will not be toxic at this time In fact, this is wrong There is no pungent smell, but formaldehyde volatilizes to a level acceptable to human physiology The benzene, toluene and free TDI contained in paint curing agent and diluent are still volatilizing It will take at least decades for these things to volatilize completely These aromatic substances have a great impact on the intellectual development of infants and unborn children Free TDI also has the risk of carcinogenesis In developed countries in Europe, the use of paint has been banned for a long time Generally speaking, the development stage of waterborne paint technology mainly experienced the following three stages: the first generation of waterborne paint with acrylic acid as the main raw material, its advantages are good water resistance and weather resistance, and it is the main product of the current waterborne paint manufacturers to the market Its disadvantages are general comprehensive performance, low chemical performance (for example, poor alcohol and alkali resistance), low hardness, wear resistance and other physical indicators, which is also the reason why most people think the water-based paint is not good The second generation of waterborne paint takes the compound of acrylic acid and waterborne polyurethane as the main raw material It not only inherits the advantages of the first generation of acrylic acid products, such as good weather resistance and construction tolerance, but also improves the hardness of waterborne paint However, its chemical properties are still relatively low At present, there are only a few domestic enterprises that can produce it, which is the middle-class product in waterborne paint The third generation of waterborne paint takes acrylic modified waterborne polyurethane as the main raw material On the basis of the second generation of waterborne paint products, the comprehensive performance of the products is greatly improved The pencil rule test hardness can reach more than 2h, which fully meets the needs of daily production; the wear resistance even exceeds that of the oily paint, with obvious advantages in service life and color allocation; More importantly, the chemical property is stable, and the alcohol and alkali resistance are greatly enhanced compared with the former two It is a high-grade product of waterborne paint At present, the technology is monopolized by a few manufacturers at home and abroad Although the water-based paint has the advantages of good environmental protection film effect, there is still a certain gap between the single component water-based paint and the two-component oil-based paint in hardness, high temperature resistance and other properties For example, it is very easy to show its lack of performance when used on the dining table and floor This functional defect led to the development of waterborne paint The fake two-component water-based paint on the market, just like the apple mobile phone, often comes out in an endless stream Before Asahi launched the two-component water-based paint, some small paint factories in the market began to launch the so-called two-component water-based paint, which is actually an improved product of paint, although its hardness has been improved a lot, but it contains a lot of toxic substances like ordinary paint, which violates the original intention of water-based paint to protect the environment and human health with environmental protection and non-toxic 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,
