A wood modification working fluid for wet board processing and its application method

Abstract

The invention discloses a wood modification working liquid used for wet plate processing and a use method thereof. The wood modification working liquid used for wet plate processing is prepared from, by weight, inorganic base resin, namely an alkaline silica solution with 2-30% of silicon dioxide by weight, organic base resin, namely water soluble urine aldehyde resin impregnation liquid with 2-30% by solid content, waterproof agents with 0.2-20% by solid content, 0.05-3% of silane coupling agents, 0.2-1% of emulsifying agents, 1-10% of fire-retardant preservative and the balance water through mixing. The wood modified working liquid adopts matching of the inorganic component and the organic component, so that wood has the functions of preventing corrosion and insects, retarding inflaming, being waterproof and the like. All the components are not polymerized by themselves and can meet production requirements; the combination capacity of the components with the wood is high; the leach resistance is high; the obtained modified wood is good in stability, high in waterproof performance and good in corrosion prevention and fire resistance.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to a wood modification working fluid for wet board processing and a method for using the same. Background technique [0002] my country is a big consumer of wood in the world, and it is also one of the countries with the least per capita forest (timber) resources in the world. With the rapid development of the economy and the improvement of people's living standards, the consumption of wood in our country has further increased, and the contradiction between supply and demand has further intensified. In 2006, my country's total wood consumption was 337 million m 3 , domestic annual supply of 140 to 150 million m 3 , the gap in timber market supply reaches 160 million m 3 above. Calculated according to the average annual growth rate of my country's wood consumption of 3.71% in the past 10 years, it is estimated that China's wood consumption will reach 600 million m by 2020...

AI Technical Summary

Problems solved by technology

[0005] Existing wood modifier, the main component is urea-formaldehyde resin or phenolic resin, the product formaldehyde release amount of making is high, not environmental protection, urea-formaldehyde resin or phenolic resin also exists storage short, reusability is poor (will gradually self-polymerize, solidify ), high production costs and other defects

In addition, when using such a wood modifier, the wood needs to be dried (with a moisture content of less than 20%) before it can be impregnated, resulting in high energy consumption and production costs
