Problems solved by technology

[0002] At present, in the process of preparing acrylate adhesives, toluene solvent or a mixed solvent of toluene and ethyl acetate are usually used. From the perspective of process control and product performance, toluene and ethyl acetate can improve the dispersion of polymers, thereby improving the performance. It is more superior, but from the perspective of environmental protection, the current environmental requirements are becoming more and more stringent. Toluene, as a high-boiling point toxic chemical solvent, is gradually being resisted. It is required that toluene should no longer be used as a dilution medium in high-end acrylic adhesives, but non-toluene should be used When using solvent-like solvents, the traditional preparation process is difficult to obtain good product performance, and the process needs to be improved

Abstract

A preparation technology of an acrylate adhesive comprises the following steps: a, raw materials are taken in a weight ratio; b, part of butyl acrylate, iso-octyl acrylate and ethyl acetate are taken and added to a reactor and stirred; c, part of acrylic acid and 2-hydroxyethyl acrylate are taken and added to the reactor in the step b and stirred; d, part of butyl acrylate, ethyl acetate, acrylic acid and 2-hydroxyethyl acrylate are taken and added to the reactor in the step c and stirred; e, an initiator is taken, divided into 6 parts and dissolved in ethyl acetate respectively, six solutions are added to the reactor in the step d sequentially, and after addition, the mixture is stirred; f, resin is taken and dissolved in ethyl acetate, the mixture after dissolution is added to the reactor in the step e and stirred, and the acrylate adhesive is obtained. According to the preparation technology, a non-toluene solvent is used, environment-friendliness is realized, the technology is optimized, the polymer dispersion is improved, and a down-stream product meets the environmental protection requirements for low VOC (volatile organic compounds) quantity and low total carbon on the premise that the performance is guaranteed.
