Is there formaldehyde in the interior wall latex paint? Is latex paint toxic?

After the renovation of new houses, a certain amount of formaldehyde will generally remain, which comes from many sources. It is common that formaldehyde is contained in building materials products, such as paint like interior latex paint, or other newly bought furniture. , which will contain more or less toxic and harmful substances such as formaldehyde. So today, Bian Xiao gives one example, that is, the detection of formaldehyde in indoor latex paint, which can deeply analyze the harm for everyone and help you buy the right products.

1. Is there formaldehyde in the interior wall latex paint?

Yes, it's an adhesive. As long as they are widely used in architecture, furniture manufacturing and daily life, these adhesives can volatilize a large number of organic pollutants, including phenol, cresol, formaldehyde, acetaldehyde, styrene, ethylbenzene, acetone, diisocyanate, vinyl acetate and epichlorohydrin.

Latex paint mainly contains benzene series, and the content of brand latex paint is much less Furthermore, because the wall is made of latex paint, the benzene inside is easy to volatilize, so the general wall and paint are dry and the benzene will not exceed the standard. Don't believe the saying that there is no benzene paint. Any paint should use benzene series as raw materials, just as there must be formaldehyde in glue. There is no real formaldehyde-free glue, only low formaldehyde glue.

Generally, there is formaldehyde in paint, but it depends on the content. Latex paint usually contains little.

A large number of synthetic resin emulsion interior wall coatings used for interior decoration have not used substances containing formaldehyde as raw materials in the production process. However, in order to improve the performance, some coatings may use additives containing formaldehyde (such as mildew inhibitors, etc.). ), but the content is very little. The raw materials of polyvinyl formal water-soluble coatings contain formaldehyde. If the reaction is not complete in the production process, the paint will inevitably contain free formaldehyde, which will be harmful to human body when the paint is used. Therefore, formaldehyde also exists in the paint.

For this kind of formaldehyde, there is actually no great danger in taking measures. During and after the renovation, keep the air circulating, and if possible, put some plants, such as chlorophytum, aloe, Hupilan, etc., to reduce the presence of formaldehyde more effectively.

Second, is latex paint toxic?

Latex paint should be basically non-toxic, belonging to green products and water-based coatings. Their film performance is much better than that of solvent-based coatings, but here the organic solvent which accounts for half of solvent-based coatings is replaced by water. Therefore, the toxicity of organic solvents is basically solved by latex paint. Not all latex paints are 100% nontoxic and harmless. The possible harmful substances in latex paint are: 1. Formaldehyde; 2.？ Other organic solvents: including dichloromethane, chloroform, benzene, toluene, etc. 3.？ Heavy metals: including lead, cadmium, chromium, mercury, etc.

In order to avoid the threat to human health caused by excessive formaldehyde in interior wall latex paint, we have to do a lot of operations. First of all, it is natural to control the selection before purchase, such as referring to the identification parameters of products, referring to the detailed guidelines formulated by relevant departments, or referring to the suggestions and analysis of relevant people to eliminate unqualified products; Secondly, it is necessary to analyze the later detection, such as asking professional institutions to determine the formaldehyde content in the air to avoid harm.
