Nano photocatalyst composite material and preparation method and application thereof

Abstract

The invention provides a nano photocatalyst composite material, and belongs to the field of air purifying. The composite material comprises, by weight, 10-18 parts of a formaldehyde collecting agent,5-10 parts of a nano photocatalyst, 5-8 parts of nano silver ions, 5-7 parts of negative oxygen ion powder, 15-20 parts of a deodorant and 40.3-52.1 parts of water. According to the composite material, under the dual-effect compound action of the formaldehyde collecting agent and the nano photocatalyst, organic pollutants of formaldehyde, benzene, toluene and dimethylbenzene can be effectively removed, the organic pollutants can be collected and decomposed through chemical reaction to effectively change the spatial structures of organic molecules, and the organic molecules are converted into harmless molecules without smell; in addition, under the cooperative action of the silver ions and the nano photocatalyst, the nano photocatalyst composite material can effectively sterilize bacteria and microorganisms, and odors can be effectively removed under the action of the deodorant.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a nano photocatalyst composite material and its preparation method and application. Background technique [0002] Air is one of the important external environments that human beings depend on for survival. Surviving in an environment polluted by harmful gases such as formaldehyde, benzene, toluene, and diphenyl can cause eye, nose, throat, and respiratory irritation, as well as headache, dizziness, nausea, Chest tightness, lack of energy and other symptoms. The World Health Organization (WHO) research shows that long-term exposure to harmful gases such as formaldehyde, benzene, toluene, and diphenyl may cause malignant diseases such as cancer and leukemia. [0003] As a large number of new houses are put into use, the demand for interior decoration and building materials and furniture is increasing day by day. Modern architectural decoration and the extensive use of composite fur...

Problems solved by technology

[0004] At present, there are many methods to deal with peculiar smell and indoor pollution. The main method is to use air fresheners mainly based on essence, which "cover up" the peculiar smell on the surface, so that people's feeling of peculiar smell can be alleviated, but in fact, the peculiar smell and pollution have not been completely eliminated; or It uses the adsorption of activated carbon and plants, but this method has limited effects and does not fundamentally solve the pollution problem
