Paint knowledge: does latex paint contain formaldehyde

Core tip: latex paint mainly contains benzene series, high-end brand latex paint content is much less At the same time, because the emulsion paint is used on the wall surface, so the benzene inside is easy to volatilize, so the high-end brand of emulsion paint is completely dry on the wall, and the benzene is not over the standard Don't believe that there is benzene paint The paint is made of benzene series as raw material Just like formaldehyde in the glue, there is no real aldehyde free glue, only low aldehyde glue The content that is low enough for the human body to be unaffected is of high environmental protection grade The top coat and primer of the common brand latex paint on the market are water-based, and the environmental protection index of the water-based latex paint is higher than that of the ordinary emulsion Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: latex paint mainly contains benzene series, high-end brand latex paint content is much less At the same time, because the emulsion paint is used on the wall surface, so the benzene inside is easy to volatilize, so the high-end brand of emulsion paint is completely dry on the wall, and the benzene is not over the standard Don't believe that there is benzene paint The paint is made of benzene series as raw material Just like formaldehyde in the glue, there is no real aldehyde free glue, only low aldehyde glue The content that is low enough for the human body to be unaffected is of high environmental protection grade The top coat and primer of the common brand latex paint on the market are water-based The environmental protection index of the water-based latex paint is much better than that of the common latex paint The so-called water-based emulsion paint is simply the emulsion paint that can be diluted with water The mixture of the dispersion of the solid particles of synthetic resin in water and the dispersion of the pigments and fillers in water makes the proportion of the components containing benzene harmful substances in the emulsion paint greatly reduced to negligible The main harmful substances in latex paint are soluble heavy metal content (free formaldehyde content) and volatile organic compounds (VOC) Free formaldehyde refers to that in the production process of paint emulsion paint, a small part of formaldehyde does not participate in the reaction and becomes free formaldehyde Volatile organic compounds (VOCs) refer to the compounds with boiling point of 50 ℃ - 250 ℃ as defined by the World Health Organization The saturated vapor pressure at room temperature exceeds 133.32kpa VOCs exist in the air in the form of vapor at room temperature If the content of paint is too much, people will feel headache, nausea, vomiting and weakness of limbs in a short period of time; in serious cases, people will have convulsions, coma and memory loss In the newly issued "code for the control of indoor environmental pollution in civil buildings", the content of VOCs in indoor air has become an important item to evaluate the indoor air quality The content specified in this standard is 0.5mg/m3 for class I civil construction engineering and 0.6mg/m3 for class II civil construction engineering Formaldehyde is a colorless irritant gas with strong smell, which can combine with protein itself After inhalation of high concentration formaldehyde, it will cause serious irritation and edema of respiratory tract, eye tingling, headache, asthma and other symptoms Therefore, we must pay special attention to VOC content and formaldehyde content when choosing latex paint 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,
