Embodiment 1

[0028] Anti-mildew dry powder coating raw materials (parts by weight):

[0029] 50 parts of cement, 40 parts of redispersible rubber powder, 20 parts of titanium dioxide, 2.5 parts of silver oxide, 5 parts of cetylpyridinium chloride, 15 parts of accelerator, 6 parts of anti-mold additive.

[0030] The anti-mildew additive is obtained by uniformly stirring and mixing zinc oxide, magnesium oxide and zirconium carbonate in a mass ratio of 1:1:1.

[0031] The quick-setting agent is obtained by stirring and mixing potassium silicate, potassium sulfate and strontium carbonate in a mass ratio of 1:1:1.

[0032] The preparation method of anti-mildew dry powder coating: mix cement, redispersible rubber powder, titanium dioxide, silver oxide, cetylpyridinium chloride, quick-setting agent, and anti-mold additives for 15 minutes with a cantilever double-helix conical mixer and mix them evenly. .

Embodiment 2

[0034] It is basically the same as in Example 1, except that the anti-mold additive is obtained by stirring and mixing zinc oxide and magnesium oxide in a mass ratio of 1:1. Obtain the anti-mildew dry powder coating of embodiment 2.

Embodiment 3

[0036] It is basically the same as in Example 1, except that the anti-mold additive is obtained by stirring and mixing zinc oxide and zirconium carbonate at a mass ratio of 1:1. Obtain the anti-mildew dry powder coating of embodiment 3.

Abstract

The invention discloses a mildew-resistant dry powder coating. The mildew-resistant dry powder coating is prepared from, by weight, 48-52 parts of cement, 40-50 parts of redispersible rubble powder, 18-22 parts of titanium dioxide, 0.6-4 parts of silver oxide, 2-9 parts of cetylpyridinium chloride, 12-18 parts of a setting accelerator and 5-10 parts of a mildew-resistant additive. The mildew-resistant dry powder coating has the advantages of improved mildew resistance and antibacterial property, excellent stability, lasting mildew resistance, convenience in production and use, and low cost.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-mildew dry powder coating. Background technique [0002] As the global population continues to increase and the temperature warms, mold can infiltrate people anytime and anywhere. Especially in hospitals, residences, pharmaceuticals and food industries, environmental pollution is often caused by the reproduction of bacteria and molds on painted surfaces and interiors. In order to improve human health and improve the living and working environment, research and development of new, high-efficiency, non-toxic, odorless and good antibacterial and durable anti-mold coatings is a major technical improvement over traditional coatings on the market. It has been favored by people since it came out. . [0003] Coating is a kind of building material, which is applied on the surface of objects by different construction techniques to form a solid adhesion, a certain strength, and a...
