A kind of wood modification liquid and its preparation method

Abstract

The invention relates to a wood modification liquid and its preparation method. The basic phenolic resin and sodium silicate are the main components of the modification liquid and act as fillers inside the wood fiber of the modified wood, so that the wood can be obtained The hardness is improved; the filling of styrene-acrylic emulsion can increase the flexibility of wood; the addition of aluminum stearate and epoxy fatty acid methyl ester in the preparation stage can stabilize the synthetic molecules in the liquid and improve the stability of the filler molecules and, using sodium alkylbenzene sulfonate as a penetrating agent can make the chemical liquid fully enter the fiber tissue of the wood, and then using the silane coupling agent as a fixing agent can make the filling in the wood full. Production practice proves that the wood modification liquid involved in the present invention has wide applicability, and the specific gravity of the formula can be adjusted according to different woods, and then the finished modified wood can be obtained according to the preparation method of the present invention.

Description

technical field [0001] The invention relates to a modifier used for wood modification and a preparation method, in particular to a wood modification liquid. Background technique [0002] The main purpose of wood modification is to improve the durability of wood. For this reason, how to make the wood itself water-repellent has naturally become a problem that the industry will focus on solving; more technical solutions are to do enough homework on the problem of improving the modifying liquid. Its advantage is that the wood soaked in the modified solution can reduce the fracture of the board and the profile, and can improve the tolerance of microorganisms and ant insects to it. For example, Chinese Patent CN101267921A discloses "Use of Modified Wooden Materials in the Production of Products" which mentions how to make modified woody materials using crosslinkable nitrogen compounds distributed in wood in a crosslinked form. Chinese patent CN8610228B announcement "a kind of mo...

AI Technical Summary

Problems solved by technology

[0004] However, in production practice, it is found that whether the filler inside the fiber of the finished wood is uniform and full, and whether the flexibility of the modified wood itself can be greatly improved are still the main issues today, especially in improving the quality of modified wood. There is still a lot of room for creativity in the adjustment and preparation of its modifiers in terms of quality
