Abstract

The invention provides an environment-friendly water-based paint capable of quickly decomposing formaldehyde. The environment-friendly water-based paint comprises the following components in parts by mass: 45-55 parts of alkyd resin; 25-35 parts of a solvent; 15-25 parts of color paste; 0.5 to 0.8 part of a defoaming agent; 1.0 to 1.5 parts of a dispersant; 5-15 parts of a curing agent; 5 to 15 parts of Pt/Bi2O3 powder; the Pt/Bi2O3 powder is added into the environment-friendly water-based paint capable of quickly decomposing formaldehyde, the Pt/Bi2O3 powder can degrade gaseous formaldehyde on the outer side of a paint surface and reduce the concentration of the formaldehyde on the outer side of the paint surface under the same action of room temperature and indoor illumination, so that outward volatilization of the formaldehyde on the paint surface is accelerated, the volatilized formaldehyde can be continuously decomposed by the Pt/Bi2O3 powder, and the formaldehyde can be quickly decomposed by the Pt/Bi2O3 powder. The virtuous cycle is achieved, and formaldehyde volatilization of the paint surface is accelerated; formaldehyde volatilized after the paint surface is arranged can be decomposed in time, so that the damage to the health of people is avoided.

Description

technical field [0001] The invention belongs to the technical field of paints, and in particular relates to an environment-friendly water-based paint capable of rapidly decomposing formaldehyde. Background technique [0002] Paint is a chemical mixture coating that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. With the rapid development of the economy, people's living standards continue to improve. People have higher and higher requirements for the comfort and aesthetics of the living environment and working environment. Various paints and coatings are more and more used in the decoration of consumer goods such as houses, fixtures, and automobiles. At the same time, it has also brought a series of The problem of indoor air pollution, especially the continuous release of toxic and harmful substances in paint coatings, seriously threatens people's health. Formaldehyde is one of the main toxic and harmful substances in...
