Abstract

The invention discloses a new wood modification composition and its preparation method and application. The composition is mainly made of the following raw materials: 37% formaldehyde, borax, ammonia water, urea, melamine, boric acid, dicyandiamide phosphate, High carbon alkyl quaternary ammonium salt, sodium lauryl sulfate, sodium alkylphenol ether sulfosuccinate, decylphenol polyoxyethylene ether, N-methylol acrylamide, butyl acrylate, styrene, Isooctyl acrylate, acrylic acid, tertiary dodecyl mercaptan, ammonium persulfate, sodium bicarbonate, sodium metasulfite, chlorinated paraffin with a chlorine content of 50-60%, silica microemulsion with a solid content of 45% and/or 40 % solid content of hydrated aluminum oxide microemulsion. The artificial forest and low-grade wood modified by the composition of the present invention not only have significantly improved physical and mechanical properties, but also have excellent fire-retardant, moth-proof, mildew-proof and anti-corrosion properties, and also overcome the existing wood preservatives. Generally contain defects such as heavy metal ions and other toxic components.

Description

technical field [0001] The invention relates to a composition for wood modification and a preparation method thereof, in particular to a composition for modification of artificial forest materials and other low-grade wood, and belongs to the field of forestry chemical industry. Background technique [0002] Densifying and modifying wood to increase its density, and then increase its physical and mechanical properties such as hardness and strength, is a feasible way to improve the quality of wood. For example, unsaturated olefin monomer or prepolymer is injected into wood tissue, and then under the initiation of thermal initiator or thermal radiation source, it is polymerized and solidified in wood to form a wood-plastic composite (Zhu Wei, Guo Fengping. Plastic New developments in wood research [J]. Journal of Northwest Forestry University, 1998, 13(4): 82-91; edited by Lu Wenda. Wood Modification Technology [M]. Harbin: Northeast Forestry University Press, 1993; Feist W C,...
