Abstract

The invention discloses a wood modifier and a preparation method thereof, and relates to the technical field of wood chemical modification. The wood modifier disclosed by the invention is prepared from the following raw materials in parts by weight: 5-10 parts of a triazole compound, 10-20 parts of hydroxyethyl methacrylate, 0.5-0.8 part of a catalyst, 10-20 parts of ammonium dihydrogen phosphate,20-40 parts of a nonionic surfactant, 45-90 parts of polyethylene glycol and 300-800 parts of water. The invention further discloses a preparation method of the wood modifier. The wood modifier provided by the invention can stabilize the size of wood treated by the modifier, has excellent hardness, bending strength, impact toughness and loss resistance, also has waterproofness and flame retardance, and prolongs the service life of the modified wood. The raw materials of the modifier are non-toxic and environment-friendly and are pollution-free to human bodies and the environment, and the application range of modified wood is widened.

Description

technical field

[0001] The invention belongs to the technical field of wood chemical modification, in particular to a wood modifier and a preparation method thereof. Background technique

[0002] With the rapid development of industry, the pollution has become more and more serious. Countries have successively introduced policies to limit deforestation, so that the cost of timber imports is increasing. For this reason, my country has begun to plant a large number of artificial fast-growing forests such as poplar, fir, and rubber trees. . Although the artificial fast-growing forest has a shorter growth period, compared with the natural forest, the density, physical and mechanical strength and dimensional stability of the fast-growing forest are relatively poor, which limits its application in the field of high value-added wood processing. How to expand the application range of artificial fast-growing trees and increase their hardness and strength by physical or chemical means...
