Embodiment 1

[0022] The raw materials used are calculated by weight: 60 parts of deionized water, 8 parts of titanium dioxide, 10 parts of silver nitrate, 2 parts of defoaming agent, 2 parts of wetting agent, 0.3 part of thickener, and 15 parts of fluorite powder. 0.3 parts of film-forming aids, 1 part of zinc oxide, and 4 parts of silicon dioxide. Wetting agent is a mixture of polyoxyethylene polyol ether and polyol ester, defoamer is a mixture of aliphatic hydrocarbon emulsion and non-silicone organic ester hydrocarbon, thickener is modified sodium polyacrylate, film-forming The auxiliary agent adopts the auxiliary agent of the model BYK-194 produced by the German BYK company. The above raw materials are placed in a container to mix and stir (stirring cowpea is 450 rpm) to make a hydrosol.

Embodiment 2

[0024] The raw materials used are calculated in parts by weight: 50 parts of deionized water, 18 parts of titanium dioxide, 6 parts of silver nitrate, 3 parts of defoamer, 6 parts of wetting agent, 0.3 part of thickener, and 15 parts of phosphorus-containing powder. 0.3 parts of film aid, 3 parts of zinc oxide, and 3 parts of silicon dioxide. The wetting agent is a mixture of polyoxyethylene polyol ether, polyol ester and polyoxyethylene alkaryl ether. The defoamer is a mixture of mineral oil-based silicon-containing mixture and non-silicone organic ester hydrocarbon, the thickener is a mixture of modified polyacrylamide and non-ionic polyurethane compound, and the film-forming aid is BYK, Germany The additive manufactured is BYK-194. The above raw materials are placed in a container to mix and stir (stirring cowpea is 450 rpm) to make a hydrosol.

Abstract

The invention discloses a novel catalyst includes following raw materials, by weight: 35-100 parts of deionized water, 5-25 parts of titanium dioxide, 6-15 parts of silver nitrate, 2-5 parts of a defoaming agent, 2-8 parts of a wetting agent, 0.1-0.5 parts of a thickening agent and 15 parts of a nature luminescent agent. In the invention, the nature luminescent agent and metal catalysts are added on the basis of a formula of a catalyst in the prior art so that the novel catalyst has a quite excellent light-free catalytic effect. By means of the novel catalyst, various organic substances adhered onto a surface of a filter screen base material can be decomposed and removed even under a light-free condition. The novel catalyst has a strong air purifying function.

Description

technical field [0001] The invention relates to the technical field of catalysts, in particular to a long-acting antibacterial and decontamination composite catalyst and a filter screen thereof. Background technique [0002] At present, indoor environmental pollution has caused great harm to humans, especially young people. The well-known "indoor air killers" such as bacteria and viruses endanger people's health. Organic volatiles such as formaldehyde and benzene are also important sources of pollution. These toxic gases can cause people to be poisoned unconsciously, gradually appear symptoms such as headache and fatigue, and reduce the body's immunity. [0003] Photocatalyst is currently an ideal environmental purification material, which can effectively degrade formaldehyde, benzene, toluene, xylene and other harmful organic substances that affect human health. Photocatalysts mostly use nano-titanium metal oxides to achieve antibacterial, but the solution still needs ult...
