Problems solved by technology

However, raw lacquer also has some defects, such as causing human allergies, special conditions for film formation, high viscosity, difficult construction, poor alkali resistance, etc. Therefore, people extract its main film-forming substance- urushiol from raw lacquer. Modified, let it react with formaldehyde, furfural, etc., and made a variety of polymer synthetic resins with excellent performance, avoiding the toxicity of raw lacquer
However, the aldehydes introduced in this process will have a certain impact on both environmental pollution and human health.

Abstract

The invention discloses a synthetic method of urushiol biology base resin. The urushiol biology base resin comprises the following materials in mass percent: 15 to 25 percent of urushiol, 8 to 10 percent of vegetable oil, 5 to 10 percent of binary estolide, 4 to 8 percent of glycerol, 3 to 6 percent of pentaerythritol, 0.5 to 2 percent of catalyst, 0.01 to 0.09 percent of color reducing agent, 1 to 5 percent of drier and 50 to 60 percent of solvent oil, wherein the sum of percentage of the material is 100 percent. The urushiol biology base resin has the characteristics of environment protection, high hardness, good dryness nature, high flexibility, water resistance, corrosion resistance, weather resistance and the like, and can be widely applied to industries of architectural ornament, furniture and flooring, road and bridge, industrial maintenance, vehicle boat and the like.

Description

technical field [0001] The invention relates to the technical field of resin and its synthesis and preparation, in particular to a urushiol bio-based resin and its synthesis method. The synthesized urushiol resin is an intermediate, especially suitable for preparing heavy-duty anti-corrosion coatings and other special functions Coating resin. Background technique [0002] Raw lacquer is natural lacquer cut from trees. It is a special resource of our country and a treasure bestowed by nature to human beings. The use of raw lacquer has a long history, and there are records about lacquer trees as early as the ancient times in China. After drying, the raw lacquer has zero pollution, non-toxic and non-radiation, excellent acid resistance and corrosion resistance, and is the best product for pursuing nature and environmental protection. However, raw lacquer also has some defects, such as causing human allergies, special conditions for film formation, high viscosity, difficult co...
