Application:

Epoxy resins are widely used as adhesives, anti-corrosion materials, insulating coatings, laminates, casting and dipping materials, and molding materials. It can also be used as glass fiber reinforced plastics, electrical precision parts, shock-proof and sound-absorbing materials, and textile finishing agents. In terms of coatings, it is mainly used as a metal protective coating for protective coatings for ships, steel components, metal containers, etc.; in addition, as a vehicle for cationic electrophoretic coatings, it is widely used as a primer for car bodies; widely used as a Chemicalbook in electrical appliances. Insulating paint, injection molding materials, molding materials, especially in the electronics industry, are widely used as sealing materials for LSI, IC, etc. in addition to laminates; in civil construction, they are used as non-slip dressings, floor materials, and mortar materials for concrete casting roads; As an adhesive, it is widely used in the bonding of metal and non-metal materials (such as ceramics, glass, wood, etc.) with good adhesion; also used as a stabilizer for resins and polyvinyl chloride; textile treatment agent, can Prevent wrinkles and scale reduction.

Production method:

Generally speaking, the preparation method of epoxy resin can be summarized into two methods, one of which is to use compounds containing active hydrogen, such as compounds containing hydroxyl, carboxylic acid groups, amino groups, etc., as raw materials, under the catalysis of alkali, and Epoxy compounds (such as epichlorohydrin) are reacted and epoxy groups are introduced, such as the preparation of bisphenol A epoxy propyl ether epoxy resins. Compounds such as tetrahydrophthalic acid, cyclohexene, etc. are used as raw materials, and then peroxides are used to epoxidize the ethylenic bonds to form epoxy groups. For example, epoxy resins made by reacting with compounds containing ethylenic bonds are all This type. The synthesis of bisphenol A type epoxy resin varies with the relative molecular mass. The liquid epoxy resin with low molecular weight makes bisphenol A react with excess epichlorohydrin Chemicalbook alkane under the action of potassium hydroxide (sodium) to epoxidize it. In order to inhibit the formation of high molecular weight compounds and the hydrolysis of epichlorohydrin, lye should be added slowly. For epoxy resins with medium molecular weight, a one-step method is used. That is, bisphenol A (or other basic substance) is dissolved in sodium hydroxide, and then epichlorohydrin is gradually added to react. This method can save the amount of epichlorohydrin. For high molecular weight epoxy resins, there are two methods: one is the one-step method. Dissolve bisphenol A in sodium hydroxide, then add epichlorohydrin, and then add a part of sodium hydroxide, and finally dehydration and refining; the second is a two-step method, in which the epoxy resin is prepared and added Bisphenol A is allowed to react further to increase the relative molecular weight. This is because the epoxy resin has epoxy groups at both ends, which can react with Bisphenol A under certain conditions.
