Problems solved by technology

[0005] 1. The purification efficiency of the plant absorption method is limited, the effect is too slow, and the effect is not obvious;
[0006] 2. The spraying effect of purifiers is not long-lasting, and some purifiers only cover up the smell and cannot eliminate formaldehyde;
Activated charcoal works well, but like other methods, it cannot completely remove formaldehyde from the air

Abstract

The invention discloses a low-smell high PVC emulsion paint composition capable of reducing the indoor formaldehyde content. The composition contains, by weight, 13-15 parts of a film forming material, 47-49 parts of a pigment filler, 4-5 parts of a functional adsorption material, 3-6 parts of a coating additive, 0.3-0.5 parts of a film forming aid and dilution water, wherein the film forming material is an acrylic copolymer emulsion with a diacetone active functional group, the functional adsorption material is porous silicastone diatomite, and the volume concentration of the pigment is 70-75. High PVC emulsion paints prepared by using the composition have very good routine performances of a coating, can adsorb and decompose formaldehyde, and can meet many demands of consumers.

Description

technical field [0001] The invention relates to a latex paint composition, in particular to a high-PVC latex paint composition which has low odor and can reduce indoor formaldehyde content. Background technique [0002] In recent years, the issue of free formaldehyde released by interior decoration materials has attracted more and more attention. When people live in an environment where formaldehyde exceeds the standard for a long time, symptoms such as abdominal pain, respiratory diseases, liver damage, renal failure, and chromosomal lesions will occur. Protection has become an urgent problem to be solved. [0003] Traditional formaldehyde purification methods include: 1. Plant absorption method; 2. Purifier spraying; 3. Activated carbon adsorption, etc. [0004] The disadvantages of traditional indoor formaldehyde purification are: [0005] 1. The purification efficiency of the plant absorption method is limited, the effect is too slow, and the effect is not obvious; ...
