Embodiment 1-3

[0022] Embodiment 1-3: Weigh each raw material according to the corresponding data in Table 1, mix the mixture of diterbium trioxide and tetraterbium heptoxide, tourmaline and opal evenly, pulverize and grind, and control the particle size D50≤0.5 micron to obtain the The above-mentioned negative ion additives. Then the negative ion additive is added into the base material by 1% by weight.

Embodiment 4-7

[0023] Embodiment 4-7: Weigh each raw material according to the corresponding data in Table 1, mix diterbium trioxide, tetraterbium heptoxide tourmaline and opal evenly, pulverize, grind, control the particle size D50≤0.5 micron, and the negative ion can be obtained additive. Then the negative ion additive is added into the base material by 1% by weight.

[0024] Base material ratio:

[0025] 40 parts of water; 3 parts of potassium methyl siliconate; 1 part of 5040 dispersant; 0.3 parts of wetting agent ethylene glycol; 10 parts of titanium dioxide; 20 parts of hydroxyethyl cellulose 3000; 20 parts of SF-109 emulsion; 11 parts of glue powder; 12 parts of gelatin powder.

Embodiment 8

[0026] Embodiment 8: adopt the method for embodiment 1, add titanium dioxide in formula and be Fe3+doped nanometer titanium dioxide, Pt 4+ A mixture of ion-doped nano-titanium dioxide and N-doped nano-titanium dioxide, Fe3+ doped nano-titanium dioxide, Pt 4+ The mixing ratio of ion-doped nano-titanium dioxide and N-doped nano-titanium dioxide is 4:2:4; Fe3+ doped nano-titanium dioxide, Pt 4+ The mixture of ion-doped nano-titanium dioxide and N-doped nano-titanium dioxide is added to the base material of the coating according to the ratio of 1% by weight.

Abstract

The invention belongs to the field of coatings, and in particular relates to a coating capable of decomposing formaldehyde and releasing negative ions, wherein the coating comprises 1-1.5 wt% of a negative ion additive, 0.5-1.5 wt% of titanium dioxide and 97-98 wt% of a coating substrate; the titanium dioxide is a mixture of Fe<3+>-doped nano titanium dioxide, Pt<4+>-doped nano titanium dioxide and N-doped nano titanium dioxide, and the mixture can degrade the formaldehyde, dichloroacetic acid and 4-chlorophenol under visible light conditions; and negative ion additives are added to effectively remove a gas in air.

Description

technical field [0001] The invention relates to a coating, in particular to a coating which decomposes formaldehyde and releases negative ions. Background technique [0002] In the process of decorating houses, because many adhesives, coatings, and paints contain harmful substances such as formaldehyde and benzene, they will volatilize polluting gases mainly composed of formaldehyde and benzene, which will cause harm to the human body. Among them, formaldehyde has been determined by the World Health Organization as a carcinogenic and teratogenic substance. Long-term exposure to formaldehyde can cause chronic respiratory diseases, pregnancy syndrome, leukemia and other diseases, and can also cause chromosomal abnormalities in newborns and memory loss in parents and adolescents. Benzene is also more harmful. Benzene is volatile and easily spreads when exposed to the air. People and animals inhale or skin contact a large amount of benzene into the body, which will cause acute ...
