Tenacity-improving crack-resisting wood hardening agent and preparation method thereof

Abstract

The invention discloses a tenacity-improving crack-resisting wood hardening agent. The tenacity-improving crack-resisting wood hardening agent is made from the following raw material comprising, by weight, 10-15 parts of sodium silicate, 3-5 parts of carbamide, 10-15 parts of magnesium sulfate, 2-3 parts of guar gum, 1-2 parts of sodium carboxymethylcellulose, 0.1-0.2 part of ammonium persulphate, 2-4 parts of styrene, 4-6 parts of maleic anhydride, 3-5 parts of xylitol, 0.5-1 part of polyvinyl alcohol, 0.5-1 part of 2,2,4-Trimethyl-1,3-pentanediol monoisobutyrate, 5-10 parts of performance additives and 80-100 parts of water. The wood hardening agent has the beneficial effects of being good in permeability, not prone to running off and good in durability and having a strong ability to bond with wood. Besides, the wood hardening agent achieves a good hardening effect, is safe, environmentally friendly and capable of improving tenacity, resisting crack, prolonging the service life of wood, and has high practical value.

Description

technical field [0001] The invention relates to the technical field of wood treatment agents, in particular to a toughening and anti-cracking wood hardener and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's economy, furniture, building materials, decoration and other fields have grown stronger and stronger, and the demand for wood, especially high-quality hard wood, has gradually increased, and there has even been a shortage of supply. Fast-growing tree species such as masson pine, fir, and poplar have the advantages of rapid growth and low price, and can be used instead of natural wood. They not only have good economic benefits, but also reduce the felling of natural forest trees and protect the natural environment. However, the wood of these fast-growing tree species is light and soft, and its performance is generally poor, and its application range is limited. In order to meet the needs of providing ...

AI Technical Summary

Problems solved by technology

However, the wood of these fast-growing tree species is light and soft, and its performance is generally poor, and its application range is limited. In order to meet the needs of providing high-quality wood faster and better, it is necessary to harden it to increase hardness and improve performance. , to expand the use of wood

Currently commonly used resin-based wood hardeners are difficult to degrade in the environment, and contain certain free harmful substances, which pose potential hazards to human health

Non-resin wood hardeners have the problems of poor permeability, low binding force with wood, easy loss and poor durability

At the same time, the weather resistance of wood is poor, and it is easy to crack during storage, processing and use, which not only affects the appearance, but also shortens the service life of wood
