Abstract

The invention relates to a scavenger for scavenging formaldehyde and benzene series from woody materials and a preparation method for the scavenger. The scavenger is characterized by being prepared from the ingredients in percentage by weight: 1.25% to 1.45% of nano-titania, 5% to 8% of nano apatite, 5% to 8% of solvent produced by baking the woody materials, 0.20% to 0.28% of dispersant and 82.40% to 88.27% of distilled water, wherein the sum of weight percent of all the ingredients is 100%. According to the scavenger for scavenging the formaldehyde and the benzene series from the woody materials, disclosed by the invention, the added solvent produced by baking the woody materials has a woody compatible adhesive action and can be used for rapidly opening pore passages of woody products, so that the nano apatite and the nano-titania can thoroughly enter the interior of wood, and thus the scavenger can be used for scavenging harmful substances such as formaldehyde from the interior of the wood; meanwhile, a nano film with compactness is formed, and the formed isolating film plays a role in permanently protecting the long-acting property of the nano-titania; and the scavenger disclosed by the invention is low in cost, simple in preparation method and high in social benefits.

Description

technical field [0001] The invention relates to a scavenger, in particular to a scavenger for formaldehyde and benzene series in wood materials and a preparation method thereof. Background technique [0002] Harmful chemicals such as formaldehyde and benzene series are one of the main volatile organic compounds in indoor furniture, which are extremely harmful to the human body. Therefore, their removal is very important for improving indoor air quality and human health, and has become a matter of great concern internationally. question. [0003] The prior art proposes a paint additive for eliminating formaldehyde and a preparation method thereof. The paint additive for eliminating formaldehyde is composed of the following components in parts by weight: 5-9 parts of titanium dioxide, 4-6 parts of zinc oxide, 2-2 parts of zirconia 4 parts, 2-4 parts of hokutolite, 2-4 parts of Yiwang stone, 4-6 parts of zirconium phosphate, 3-5 parts of opal, 5-7 parts of sodium lauryl sulfat...
