Problems solved by technology

[0003] At present, the research on the high temperature resistance obtained by modification of urushiol has made great progress, for example, the modification of urushiol with non-metallic derivatives, but in In some special working environments, such as high-temperature water vapor environment or high-temperature and high-corrosion environment, so far, there are still few coating materials that meet such special environments

Abstract

The invention provides boron-modified urushiol phenolic resin, a preparation method and a coating containing the boron-modified urushiol phenolic resin. The boron-modified urushiol phenolic resin is prepared from the following raw materials: urushiol resin, boric acid and an aldehyde compound, and the boron modified urushiol phenolic resin is prepared by reacting urushiol resin with boric acid to obtain boric acid urushiol ester and then carrying out condensation reaction on the boric acid urushiol ester and the aldehyde compound. Compared with the prior art, the method has the following beneficial effects: the boric acid firstly reacts with the urushiol resin and then is condensed with the aldehyde compound, the reaction is uniform and easy to control, and the synthesized product has good leveling property and enhanced high temperature resistance and corrosion resistance.

Description

technical field [0001] The invention belongs to the field of resin coatings, and in particular relates to a boron-modified urushiol phenolic resin, a preparation method and a coating containing the same. Background technique [0002] Raw lacquer, also known as natural lacquer, earth lacquer, national lacquer, and lacquer, is a natural latex paint secreted from the bast layer of lacquer trees after being cut by hand. It is the oldest natural high-quality paint that can be cured at room temperature to form a natural film Polymer ecological resin. With the development of synthetic resins, in order to improve the physical properties of raw lacquer and reduce its consumption, the copolymerization of raw lacquer (mainly composed of urushiol) and a series of resins has become a research hotspot. Using the special structure of urushiol, Chinese scientific researchers have synthesized a series of urushiol metal complexes or complex polymers. While maintaining the original properties...
