Abstract
The present invention relates to a kind of photocatalyst formaldehyde removing composition and preparation method thereof, described photocatalyst formaldehyde removing composition includes the raw material of following parts by weight：60 parts~80 parts of 40 parts~60 parts of nano titanium oxide activated carbon, 8 parts~15 parts of yttrium modified nano-titanium dioxide powder, 20 parts~35 parts of neodymium modified nano zinc oxide powder, 20 parts~35 parts of lanthanum modified nano zinc oxide powder, 40 parts~60 parts of formaldehyde scavenger, 30 parts~50 parts of Nano Silver and water.The formaldehyde removing composition of the present invention, preparation technology is simple, with low cost, and performance is stable, after the processing through the formaldehyde removing composition of the present invention, the burst size of methanal of glued board can be down to below 0.5mg/L by 10mg/L, and the aldehyde rate that disappears is high, and the formaldehyde removing composition of the present invention, the environment-protecting and non-poisonous non-secondary pollution of ingredient, formaldehyde efficiently can be forever removed, it is applied widely, with good commercial promise.
Description
Technical field
The invention belongs to technical field of chemistry and chemical engineering, and in particular to a kind of photocatalyst formaldehyde removing composition and its preparation
Method.
Background technology
It is various containing formaldehyde with the economic development and improvement of living standards, requirement more and more higher of the people to finishing
The building and ornament materials that raw material is made largely have entered into family, such as various sheet materials, furniture, coating and decorative textile product.According to
Know, the IAQ of current 80% family does not reach the requirement of national standard, wherein 90% is caused by formaldehyde.
Formaldehyde Pollution of Indoor Air has the characteristics that：Cycle is long, even if still there is formaldehyde problem in family of the finishing after 10 years；It is exceeded tight
Weight, in formaldehyde room, most of exceeded even exceeded more than 10 times 4~5 times, had.
Formaldehyde mainly has the following aspects to health hazard：Stimulation, the main harm of formaldehyde is shown as to skin
The stimulation of mucous membrane, formaldehyde is magma noxious material, can be combined with protein, high concentration suction when respiratory tract occur serious
Stimulate and oedema, Eye irritation, headache；Sensitization, direct skin contact formaldehyde can cause allergic dermatitis, color spot, necrosis,
Bronchial astehma can be induced during suction high-concentration formaldehyde.Mutagenesis, high-concentration formaldehyde or a kind of genotoxicity material.
