Abstract

The invention relates to the field of resin production, and particularly discloses a production method of nontoxic, energy-saving and environment-friendly 820A resin. The 820A resin is formed by copolymerizing a raw material comprising methyl methacrylate, butyl methacrylate, a methacrylic acid polyfunctional group monomer, a methacrylic acid epoxy monomer and a coupling agent at a weight ratio of (20-30):(20-30):(5-10):(5-10):(5-10) in an organic solvent at 120-130 DEG C for 8-12h. According to the production method of the 820A resin, the 820A resin is matched with a crosslinking agent with reactive groups for use, is low in production cost and use cost and good in bonding performance, has the characteristics of environmental protection and no toxicity, and is short in curing time and durable in use, and the viscosity of the 820A resin cannot be influenced under the conditions of high temperature, moisture and the like.

Description

technical field [0001] The invention relates to the field of resin production, in particular to a production method of 820A resin. Background technique [0002] Adhesives used in assembling energy-saving lamps at home and abroad generally use adhesives such as silica gel, which have a long curing time and low efficiency. It has low toxicity and fails to meet environmental protection requirements. Contents of the invention [0003] The object of the present invention is to provide a kind of production method of non-toxic, energy-saving and environment-friendly 820A resin in order to solve the deficiency of above-mentioned technology. [0004] In order to achieve the above object, the production method of the 820A resin designed by the present invention will be composed of methyl methacrylate, butyl methacrylate, multifunctional methacrylic acid monomer, methacrylic epoxy monomer and coupling agent The raw materials are copolymerized in an organic solvent, the copolymeriza...
