Abstract

The invention relates to a novel acrylic ester glue, which comprises the following components: isooctyl acrylate, isobutyl acrylate, isomethyl acrylate, hydroxyethyl ester, glyceride, acrylic acid, ethyl acetate, toluene, methanol, benzoyl peroxide, and peroxide Al13N. The peroxide Al13N added in the components can protect acrylic ester glue from being oxidized by oxygen in the air during use, improves the glue stability, thermal conductivity, abrasion resistance, high temperature resistance, anticorrosion performance and other comprehensive performance, and ensures the high quality of the glue. In the preparation process, ethyl acetate is added in three times successively at different amounts, 50wt% of the raw materials are put into a reaction kettle as the kettle bottom material, and the rest 50% are added dropwise after intense reaction, the dripping time is controlled within 1h, the whole reaction lasts 3h, the reaction time is greatly shortened, the production efficiency is improved, and the preparation process is simple, therefore the method is suitable for large-scale industrialized production.

Description

technical field [0001] The invention relates to the technical field of a preparation method of glue, in particular to a novel acrylate glue and a preparation method thereof. Background technique [0002] Traditional acrylate glue is made by solution polymerization or emulsion polymerization of acrylate monomers. The preparation method is: cooling the storage tank in the reaction storage tank to take away the heat of reaction, which can be used to prepare pressure-sensitive adhesives. It can be used to directly bond other parts, but the traditional acrylate glue and its preparation method have the following defects: [0003] (1) The formula is unreasonable, resulting in poor performance of the glue; such as: higher static shear strength, higher peeling force, high temperature resistance, long-term aging resistance, better adherence to the bonding surface, low Organic gas volatilization, low surface energy material bonding; [0004] (2) The reaction time is too long, usually...
