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
