Problems solved by technology

[0003] However, there are significant defects in the process of using styrene-based thermoplastic elastomers to produce hot-melt pressure-sensitive adhesives in the prior art: on the one hand, the existing production devices are all independent production devices, which need to be reacted and cooled to prepare benzene Ethylene-based thermoplastic elastomers, and then re-melt and mix styrene-based thermoplastic elastomers to prepare hot-melt pressure-sensitive adhesives, resulting in increased energy consumption; Further increase in energy consumption, and further refining and removal of impurities are required after the solvent is extracted, which will increase the cost of energy consumption
[0004] Therefore, an integrated device and method for directly producing hot-melt pressure-sensitive adhesives is provided to solve the problems of high energy consumption and high construction costs in the production of hot-melt pressure-sensitive adhesives by using styrene-based thermoplastic elastomers in the prior art
