Abstract

The invention provides a photocatalyst type formaldehyde scavenger to solve the problems that in the prior art, the formaldehyde removing rate is low, secondary pollution is prone to being caused, and the cost is high. The photocatalyst type formaldehyde scavenger is composed of 1%-10% of a nano silver paste solution, 1%-15% of photocatalyst, 0%-5% of an N-lauroyl-L-glutamic acid surfactant, 0%-5% of polyethylene glycol, 1%-8% of a formaldehyde trapping agent, and the balance deionized water. The photocatalyst can be an anatase nanometer titania colloidal solution. The obtained photocatalyst type formaldehyde scavenger has the advantages of being high in formaldehyde removing rate, free of secondary pollution, environmentally friendly, economical and practical, and meanwhile, the photocatalyst type formaldehyde scavenger can be used for scavenging volatile organic compounds such as benzene, methylbenzene and xylene.

Description

technical field [0001] The invention relates to the field of chemistry and chemical industry, in particular to a photocatalyst type formaldehyde scavenger, which is mainly used for dealdehyde treatment of various plywood, blockboard and furniture after decoration or during decoration. Background technique [0002] With the development of the economy and the improvement of living standards, people have higher and higher requirements for decoration, and a large number of building decoration materials made of raw materials containing formaldehyde have entered the family, such as various boards, furniture, coatings and decorative textiles. Wait. It is reported that the indoor air quality of 80% of households cannot meet the requirements of national standards, 90% of which are caused by excessive formaldehyde. Indoor formaldehyde pollution has the following characteristics: the cycle is long, even after 10 years of decoration, the family still has the problem of formaldehyde exc...
