Abstract

The invention relates to the chemical field, and particularly relates to a catalyst for removing indoor formaldehyde and a preparation method thereof. The catalyst comprises, by weight, 35 to 45 parts of nano titanium dioxide, 6 to 10 parts of octaphenyl polyoxyethyiene, 6 to 10 parts of benzene, 4 to 8 parts of hydrogen peroxide, 4 to 5 parts of dimercaprol, 2 to 3 parts of DTPMP, 0.5 to 1 part of malonic acid, 0.5 to 1 part of aluminium chloride and the balancing being pure water. The catalyst quickly penetrates into the plate after being sprayed directly on the plate surface, the adhesive force is strong, and under the effects of the catalysis of titanium dioxide and other auxiliaries, the catalyst is capable of rapidly and effectively degrading indoor noxious substances including formaldehyde, benzene, toluene, dimethylbenzene, ammonia and total volatile organic compounds(TVOC). The catalyst has the advantages of low cost, strong adhesive force, good catalyst activity and long efficacy.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a catalyst for removing indoor formaldehyde and a preparation method thereof. Background technique [0002] my country's housing industry will continue to maintain a high-speed development trend in the next few years, with an annual increase of 500 million square meters of residential area, and an annual renovation of 600 million square meters of old houses. With the development of China's architectural decoration industry, in 2010 China's architectural decoration industry has become a large industry with 180,000 enterprises, more than 14 million employees, and an annual output value of 1.85 trillion yuan; in the past 20 years, the development of China's architectural decoration industry Rapidly, the annual growth rate is about 20%, which is much higher than the growth rate of GDP in the same period. At the same time, a large number of synthetic materials are widely used in inte...
