随着石油化工原料价格的上涨、天然矿物资源的逐步减少和人们对于环境友好、

With the increase in the price of petrochemical raw materials, the gradual reduction of natural mineral resources and the continuous pursuit of environmentally friendly, green and pollution-free chemical products, cardanol has become domestic and foreign in recent years due to its wide-ranging sources, low prices, and green and renewable properties. The research hotspot of scientists, the development and application of cardanol fine chemicals has become a research hotspot in the field of cardanol chemical modification. As a cheap and easily available biomass resource, cardanol has been widely used in the fields of polymer materials, adhesives, coatings, composite materials, medicines and biopharmaceuticals. <BR>Many reports on the application of cardanol and its derivatives in coatings mainly focus on the modification of cardanol to its various resins. Cardanol modified epoxy resin base material and curing agent to reduce system viscosity and crosslinking density, improve its flexibility, impact resistance, anti-corrosion and other properties; cardanol modified phenolic resin has good flexibility, high adhesion and resistance Good acidity and alkalinity, etc.; Cardanol modified polyurethane coating has the advantages of high thermal stability, good corrosion resistance, and long service life. Among them, there are many reports on the modification of epoxy curing agent by cardanol in the coating field, and the application is more extensive. <BR>Cardanol-based surfactants are widely used in petroleum, asphalt, mining, daily chemicals and many other fields, but their application in coatings is rarely reported. Cardanol-based surfactants can be used as substrate wetting agents and pigment dispersants in color pastes to reduce surface tension and stabilize the dispersion system.
