Problems solved by technology

Artificial fast-growing and high-yield forest timber mainly includes fir, masson pine, larch, poplar, paulownia and other tree species. Low hardness, no corrosion resistance, no moisture resistance, easy deformation and cracking and other defects limit its application range. Generally, it can only be used in the production of low value-added semi-finished products such as plywood, particleboard and fiberboard, but not in solid wood floors and solid wood furniture. Value-added wood products
Some wood-improving products on the market contain toxic ingredients such as triphenyl and formaldehyde, which can cause great harm to the body

Abstract

The invention discloses a wood wax oil timber modifier and a preparation method thereof. The modifier comprises the following components by mass percentage: 28-32% of tung oil, 8-12% of camphor wood oil, 17-22% of rosin-modified resin, 9-11% of orange oil, 4-6% of glass powder, and 22-27% of ethanol. The preparation method comprises the following steps: the tung oil, the camphor wood oil, rosin-modified resin, orange oil, and glass powder are placed in a reaction vessel, are subjected to a polymerization at the high temperature of 260-300 DEG C, then cooled to the temperature of 70-90 DEG C, ethyl alcohol is added for being stirred, and then the materials are cooled to the room temperature to obtain the product. The preparation method has simple process, the modifier does not contain toxic components such as triphenyl, formaldehyde and heavy metals, has no pungent smell, can keep original color when used on the timber, has the advantages of anticorrosion, insect resistance, non moisture absorption, non moistening, non deformation, and no influence on glues and paints.

Description

technical field [0001] The invention relates to the technical field of wood functional improvement, in particular to a wood wax oil wood improver and a preparation method thereof. Background technique [0002] With the depletion of natural forest resources and the implementation of the national natural forest protection project, artificial fast-growing and high-yield forest timber will become the main way to alleviate the contradiction between my country's timber supply and demand in the future. Artificial fast-growing and high-yield forest timber mainly includes fir, masson pine, larch, poplar, paulownia and other tree species. Low hardness, no corrosion resistance, no moisture resistance, easy deformation and cracking and other defects limit its application range. Generally, it can only be used in the production of low value-added semi-finished products such as plywood, particleboard and fiberboard, but not in solid wood floors and solid wood furniture. Added value millwo...
