Abstract

The invention discloses urushiol-cardanol bio-based resin and a synthesis method thereof. The prepared urushiol-cardanol bio-based resin comprises the following raw materials in mass percentage: 20-40% of urushiol, 5-20% of cardanol, 4-8% of aldehyde compound, 0.5-3% of catalyst, 40-60% of diluting agent, 0-20% of epoxy resin and 0.1-5% of curing agent, with the total percentage of 100%. The urushiol-cardanol bio-based resin solves the problems that a raw lacquer product is insufficient in supply and high in price, can be sprayed, coated and brushed, has a low requirement on a construction technology, can realize mechanized operation, does not require specific temperature and humidity conditions and can be dried under a natural condition, and a lacquer film remains the excellent performance of the urushiol resin; and the urushiol-cardanol bio-based resin has excellent comprehensive anti-corrosion performance and is an excellent intermediate of the urushiol resin.

Description

technical field [0001] The invention relates to a resin and the technical field of its preparation, in particular to an urushiol-cardanol bio-based resin and a synthesis method thereof. The urushiol-cardanol bio-based resin is an intermediate and is particularly suitable for preparing heavy-duty anti-corrosion resins Coatings and other special functional coating resins. Background technique [0002] Raw lacquer is a special product in my country, with a history of 8,000 years of use. Raw lacquer film has excellent performance, but its unique source method leads to its development mode of low output and high price, which limits its development in the industrial field. In order to expand the application of raw lacquer in the industrial field and solve the problem of high supply and price, a new type of urushiol-cardanol was synthesized by copolymerizing cheap and easy-to-obtain biomass materials such as cardanol and urushiol through the application of combinatorial chemical re...
