Abstract

The invention discloses an interior decoration coating for removing formaldehyde, and a preparation method thereof. The coating comprises aqueous polyurethane, aqueous epoxy resin, graphene oxide, nano-silica, alumina, diatomite, active carbon, a formaldehyde oxidation catalyst, a stabilizer and an antifoaming agent. The preparation method comprises the following steps: carrying out a modifying reaction on the aqueous polyurethane, aqueous epoxy resin and graphene oxide; adding the diatomite, active carbon and the antifoaming agent, uniformly mixing and stirring above substances, adding the nano-silica and alumina, and carrying out shear dispersing for 10-20 min; and adding the formaldehyde oxidation catalyst and the stabilizer, and carrying out ultrasonic dispersing for 10-20 min to obtain the decoration coating. The coating has the advantages of good coating effect, excellent waterproof property, excellent scratch resistance and good formaldehyde removal performance, can be applied to interior decoration to provide a clean and safe living environment for people, and has good application values.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to an indoor decorative coating for removing formaldehyde and a preparation method. Background technique [0002] With the improvement of living standards, indoor air pollution is gradually attracting people's attention. Studies have shown that volatile harmful gases such as formaldehyde, benzene, and toluene released by interior decoration and decoration materials are the main causes of air pollution. In order to meet the needs of the products for coagulation or hiding power or to enhance the hardness of the existing interior wall coatings, rubber, latex powder, varnish and other substances are often added to their raw materials, and these substances are the ones that produce harmful gases such as formaldehyde and benzene. Source of pollution. [0003] In the construction of interior wall paint, it is generally necessary to apply the base putty powder before applying the top paint. Th...
