Common knowledge of coating: defects of water-based fire retardant coating to be improved

Core tip: there are two kinds of waterproofing and oiliness in fire retardant coatings We mentioned that the current environmental friendly fire retardant coatings are mainly manifested in water-borne fire retardant coatings At the same time, we also mentioned that waterborne fire retardant coatings still need some improvement in the actual construction, because the Waterborne Fire Retardant Coatings currently on the market are mostly synthetic polymer emulsion, so Waterborne Fire Retardant Coatings need to be improved The defects of improvement include: 1 In low temperature (such as 0 ℃), it is difficult to store and use; 2, the emulsion itself contains some auxiliaries or film forming assistants to varying degrees (the good quality emulsion contains 2% to 5%, while the slightly bad ones contain 8% ~) 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 Home of coatings news: there are two kinds of fire-retardant coatings, water-based and oil-based We mentioned the current environmental protection The type of fire retardant coating is mainly manifested in water-borne fire retardant coatings At the same time, we also mentioned that there are still some problems to be improved in the actual construction of waterborne fire retardant coatings, because the existing water-borne fire retardant coatings on the market are mostly synthetic polymer emulsion, so the defects that need to be improved in waterborne fire retardant coatings are: 1, in low temperature (such as 0 degree) environment, its storage and application are difficult; 2, the emulsion itself contains different degree of solvent or film forming auxiliaries (good quality emulsion contains 2% to 5%, slightly worse contains 8% to 10%), they are generally slow volatile odor of high boiling point solvent 3 Compared with solvent coating, water-based coating has obvious shortcomings in water resistance and adhesion; 4 There are a large number of hydrophilic materials (such as ammonium polyphosphate) in intumescent fire-resistant coating, which are easy to migrate from the water-based coating containing emulsifier, so that the fire-resistant coating loses its fire-resistant effect Through these problems, we must take safety as the foundation, and we can't ignore its disadvantages in construction practice As long as we know these disadvantages well, we can better guarantee the integrity of construction and the spraying of the optimal scheme of fire retardant coating 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,
