overview

The polymer compound containing epoxy group in the molecular structure is called epoxy resin. Cured epoxy resin has good physical and chemical properties, on the surface of the metal and nonmetal material has excellent bonding strength, good dielectric properties, setting small shrinkage, drying products good dimensional stability, high hardness, good flexibility, the alkali solvent and most stable, and therefore is widely used in national defense, national economy departments, For casting, impregnation, laminate, adhesive, coating and other applications. In our country since 1958 open Chemicalbook epoxy resin was studied, and at the speed of fast into the industrial production, has been booming all over the world, in addition to production of ordinary – bisphenol A epoxy chloropropane type epoxy resin, it is the production of various types of new type epoxy resin, in order to meet the need for country of national defense building and economic departments. Epoxy resins can be prepared by the following methods: reaction of active hydrides with epichlorohydrin, liquid phase oxidation of the double bond by hydrogen peroxide or peracetic acid, and air oxidation of the double bond compound.

Purpose and function

Epoxy resin is widely used as adhesive, anticorrosive material, insulating coating, laminating material, casting and impregnating material, molding material, etc. It can also be used as glass fiber reinforced plastics, electrical precision parts, shockproof and sound-absorbing materials, textile finishing agent. In terms of coating, it is mainly used as metal protective coating for ships, iron and steel components, metal containers, etc. In addition, as a cationic electrophoretic coating carrier, it is widely used in the bottom coating of automobile body. Chemicalbook is widely used as insulating paint, injection molding materials, molding materials, especially in the electronic industry, in addition to the laminated board, widely used as LSI, IC and other sealing materials; In civil construction, it is used as non-slip dressing, floor material and mortar material for concrete casting road; As an adhesive, with good adhesion is widely used in metal and non-metal materials (such as ceramics, glass, wood, etc.) bonding; Also used as resin, PVC stabilizer; Textile primer to prevent crease and shrinkage.
