Problems solved by technology

Once the wood or furniture from the south is transported to the north for use, due to the large humidity difference, the moisture in the wood will volatilize, causing the wood to crack or deform, and vice versa. More importantly, the high moisture content is not conducive to the coating of furniture. During the furniture painting process, because the wood fibers are very easy to absorb water or solvents, it is easy to cause the wood to swell and affect the subsequent painting effect. Substances such as tannins in the wood will also cause troubles during the painting process of the wood.
The coating problems caused by the above factors are common in both water-based and oil-based paints, and water-based paints are particularly serious.

preparation example Construction

[0047] The preparation method of the wood modification reinforcing agent is not particularly limited in the present invention, and the components in the component A are stirred and dispersed in proportion to obtain the component A. In the present invention, after the component A, component B and component C are uniformly mixed, the wood modification reinforcing agent to be used is obtained.

[0048] The invention provides a wood modification reinforcing agent for soaking, the active ingredients of which are component A and component B, component C acts as a diluent, and works through the crosslinking reaction of component A and component B. The active imino group in component B is unstable, and it will slowly react with the glycidyl ether group in component A to release isocyanate, and then undergo a curing reaction with the hydroxyl-terminated polyurethane prepolymer in group A; while in component A Containing ether bonds such as glycidyl ether, it is a special ether bond wit...

Embodiment 1

[0057] A wood-soaked reinforcing material, composed of three components A, B, and C, the mass ratio of the three components A, B, and C is 100:30:130, and the three components are uniformly mixed before use, and the A group According to the mass ratio, it is composed of the following components:

[0058] A-100 resin: 87.5

[0059] BYK057: 0.5

[0060] BYKA501: 0.5

[0061] BYK163: 0.5

[0062] Talc powder: 10

[0063] BYK361N: 0.5

[0064] Bengel818:0.5

[0065] After the above components are uniformly mixed, disperse at 2000rpm for 30 minutes to obtain component A.

Embodiment 2

[0067] A wood-soaked reinforcing material, consisting of three components A, B, and C. The mass ratio of the three components A, B, and C is 100:50:300. The three components are uniformly mixed before use, and the A group According to the mass ratio, it is composed of the following components:

Abstract

The invention provides a wood modifying reinforcer. The wood modifying reinforcer comprises a component A, a component B and a component C, wherein the component A comprises 60-90 parts by weight of modified polyurethane resin, 0.6-1.0 part by weight of a defoaming agent, 0-1 part by weight of a dispersing agent, 0.2-0.5 part by weight of a flatting agent, 0-1 part by weight of bentonite and 0-30 parts by weight of talcum powder; the component B is isocyanate polymer; and the component C is a diluent. The wood modifying reinforcer provided by the invention is extremely strong in permeability to a wood substrate, can obviously stabilize moisture content of wood, and can slow down changes of moisture content, so that inner stress generated by rapid changes of moisture content inside the wood is reduced, the wood cracking and bending problem is prevented, and the effect of sealing tannic acid further can be remarkably achieved; and the treated wood is almost free of resin residues on surface, and is free of an obvious reinforcing phenomenon, so that convenience is provided for a follow-up processing process.

Description

technical field [0001] The invention relates to the technical field of wood treatment, in particular to a wood modification reinforcing agent. Background technique [0002] Wood is the general term for the inward development of plant tissue from the vascular cambium, including xylem and parenchyma rays, the lignified tissue of plants. Wood plays a great supporting role in human life, and it can be used in different ways according to different properties and characteristics of wood. Wood products are the products formed by processing wood raw materials. Wood products are mainly divided into the following categories: furniture wood products, office wood products, craft wood products, gardening wood products, living wood products, and now high-tech wood products and so on. Among the many types of wood products, furniture wood products are one of the most widely used wood products, which are closely related to daily life, and most of the furniture is mainly made of wood produc...
