Problems solved by technology

[0004] However, in actual use, it is necessary to heat the solvent-based pressure-sensitive adhesive to obtain a solvent-free pressure-sensitive adhesive. The process is complicated, and toxic waste gas will be generated during the process, which poses a safety hazard. Moreover, the pressure-sensitive adhesive cannot be degraded and is likely to pollute the environment.

Abstract

The invention discloses a manufacturing method of an environment-friendly pressure-sensitive adhesive material, and particularly relates to the technical field of adhesive material preparation. The environment-friendly pressure-sensitive adhesive material comprises a pressure-sensitive adhesive layer, the pressure-sensitive adhesive layer is composed of a base material, a pressure-sensitive adhesive and release paper, the pressure-sensitive adhesive is arranged on one side of the base material, and the release paper is arranged on the side, away from the base material, of the pressure-sensitive adhesive. By using poly(butylene succinate), paraffin, a tackifying emulsion, synthesized plant ester, a PVM / MA decadiene cross-linked polymer, polyoxyethylenealkylphenol ether, alkyl modified organosiloxane and a high-viscosity foam defoamer as production raw materials, a mixed filler and a mixed solvent are added, a little poisonous gas is generated in the pressure-sensitive adhesive production process, the environment is not polluted through purifying treatment in an activated carbon adsorption tower, a pressure-sensitive adhesive cut-off material is put into the filler to continue beingused, thus the resource utilization rate is increased, and the pressure-sensitive adhesive is degradable plastic, safe and environmentally friendly.

Description
