Problems solved by technology

No catalyst is used in this scheme. Even if the hydroxyl values ​​of the two components are sufficiently high during the co-reaction, the grafting rate is also very low. The organic silicon intermediate self-polymerizes at high temperature to produce a large molecular weight silicone resin, and there are still poor compatibility resins. Opacity, and the final modified resin in this scheme contains xylene and other solvents, which does not meet the technical requirements for the preparation of environmentally friendly low-odor wood wax oil

Abstract

The invention provides wood wax oil resin and a preparation method thereof and a composition containing the wax oil resin. Reaction raw materials of the wood wax oil resin comprise dry vegetable oil fatty acid, acid containing two carboxyl groups or anhydride thereof, polyhydric alcohol containing at least three hydroxyl groups and an organic silicon intermediate. According to the wood wax oil resin, an organic silicon resin structure with super-strong water resistance and weather resistance is introduced into dry alkyd resin through a chemical grafting method, so that the water resistance and weather resistance of wood wax oil prepared from the wood wax oil resin can be remarkably improved, and the protection life of the wood wax oil on woodware can be prolonged. The method is simple and feasible, and the obtained resin has high transparency and does not contain an organic solvent.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a wood wax oleoresin and a composition containing the resin. Background technique [0002] Wood wax oil is a special coating for wood protection that has emerged in recent years. It is mainly composed of vegetable oil or modified vegetable oil, vegetable wax, additives and cosolvents. The product has extremely low odor and does not contain toxic and harmful substances. Among them Oil substances can penetrate into the interior of the wood to deeply moisturize and maintain the wood; wax can be closely combined with wood fibers to enhance surface hardness, waterproof and stain-proof, so it can provide excellent beautification and protection for wood. [0003] Wood wax oil is generally a high-solid content or solvent-free wiper. You only need to wipe the wood wax oil on the wood that needs to be constructed with a dust-free cloth. After soaking for a period of time, wipe off the exc...
