Problems solved by technology

[0007] Since indoor ultraviolet light comes from the refraction, reflection and scattering of indoor sunlight and outdoor sunlight, the indoor ultraviolet light is long-wave ultraviolet light with low ability, which makes the rate of decomposition of formaldehyde low.

Abstract

The invention discloses a diatomite coating capable of decomposing formaldehyde and relates to the field of coatings. The diatomite coating comprises the following components in percentage by mass: 5%-15% of titanium dioxide, 3%-10% of nano-titanium dioxide, 2%-8% of white carbon black, 1%-3% of nano-calcium carbonate, 2%-5% of nano-silicon dioxide, 6%-18% of nano-tungsten trioxide, 2%-8% of sepiolite material, 5%-7% of chitin, 3%-6% of graphene oxide, 0.5%-1.3% of mica powder, 1%-7% of nano-activated carbon, 0.1%-0.5% of a phthalocyanin compound and the balance of diatomite. The diatomite in the diatomite coating is capable of quickly decomposing organic compounds, purifying air and effectively improving the quality of indoor air; meanwhile, the indoor negative ion concentration can be increased, which is beneficial to the human body health.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a diatom mud coating capable of decomposing formaldehyde. Background technique [0002] In the process of interior decoration, it is usually necessary to use a large amount of wood, paint, glue and coating. Since wood, glue, paint and coating contain a lot of pollutants: formaldehyde, benzene and TVOC (total volatile organic compounds), the head of the household , Usually ventilation and placement of activated carbon, green plants are used to reduce the content of pollutants. [0003] Since the pollutants are sealed in the wood clips and glue, it is difficult to volatilize completely in a short time. After the householder moves in, in order to prevent external noise and dust pollution, he usually closes the doors and windows and lives in a poorly ventilated environment. At this time, Pollutants left in wood, glue, paint and coatings will directly volatilize into the living environment an...
