Problems solved by technology

[0002] Bisphenol A epoxy resin is the largest and most widely used type of epoxy resin, because of its physical and chemical properties such as good adhesion, low shrinkage, and chemical stability, as well as low price and simple molding process , high reliability and other characteristics, it is widely used in the field of coating production and processing, and because it has certain corrosion resistance and antifouling functions, it is often used to make marine coatings. However, coatings made of bisphenol A epoxy resin are resistant to Poor impact performance and adhesion often affect the wider application of coatings prepared from it. In addition, coatings used in ships are also required to have certain flame retardant properties to meet increasingly stringent safety requirements. Therefore, the use of modified methods It is necessary to process bisphenol A epoxy resin
