Abstract

The invention discloses formaldehyde-proof interior wall coating, which consists of surface coating and base coating, wherein the surface coating at least comprises acetate/acrylic emulsion, paint or titanium white, a functional material and a filler; and the base coating at least comprises styrene-acrylate emulsion, paint or titanium white and a filler. The surface coating is prepared from the following raw materials in part by weight: 15 to 25 parts of acetate/acrylic emulsion, 25 to 35 parts of water, 15 to 20 parts of paint or titanium white, 3 to 8 parts of functional material, 20 to 30 parts of filler and 2 to 3 parts of assistant; and the base coating is prepared from the following raw materials in part by weight: 25 to 35 parts of styrene-acrylate emulsion, 20 to 30 parts of water, 5 to 10 parts of paint or titanium white, 25 to 35 parts of filler and 5 to 7 parts of assistant. The formaldehyde-proof interior wall coating has the advantages of low volatile organic compounds (VOC), slight smell, high constructability, capability of absorbing and discomposing formaldehyde in the environment, and the like.

Description

technical field [0001] The invention relates to an interior wall coating, in particular to a formaldehyde-resistant interior wall coating. The coating has the characteristics of low odor and low VOC, and has a strong absorption effect on free formaldehyde, and belongs to the technical field of environmental protection coatings. Background technique [0002] As my country puts 1 billion square meters of civil buildings into use every year, the proportion of building energy consumption to the total energy consumption of the whole society has risen from 10% in 1978 to 27.5% at present. China's paint industry has developed rapidly, and paint decoration has become a compulsory course for home decoration. [0003] However, the existing decorative coatings have high content of free monomers and free formaldehyde, which often cause coughing, sore throat, and unbearable odor after decoration, causing serious damage to the human respiratory tract.
