Problems solved by technology

[0002] Corrosion problems will cause a lot of waste of resources and energy, pollute the environment, and even cause personal casualties. With the advancement of technology and the diversification of corrosion problems, people have put forward more requirements on the varieties and properties of anti-corrosion coatings. Require
[0003] There are many types of anti-corrosion coatings. The cured epoxy resin has good mechanical properties, good chemical stability, good electrical insulation, low shrinkage, good heat resistance, high strength, easy processing and good adhesion to the substrate. It has been widely used in the field of coatings, but the cured epoxy resin has poor performance in impact resistance, peeling resistance and vibration fatigue resistance, which limits its application. Performance and impact resistance are not very ideal, need to be modified
