Abstract
The invention provides production equipment of a heat stripping polyethylene film adhesive tape. The equipment at least comprises a base body, a stepped heating roller group, a hot pressing roller group, a back roller and an ultrasonic oscillation device. When a polyethylene film is processed by the production equipment and a corresponding production method, micron-level pressure marks can be formed on the to-be-coated surface of the polyethylene film after hot pressing rolling; when a high-content heat expansion microsphere adhesion agent is coated for the first time, the adhesion agent containing high-content heat expansion microspheres is filled with the pressure marks, so that an adhesion agent layer is in better contact with a base film layer, and the reducing effect of the high-content heat expansion microspheres to viscosity of the adhesion agent is counteracted; since the high-content heat expansion microspheres are added, and the adding amount of the heat expansion microspheres in the outer adhesion agent layer is equal to a conventional adding amount, so that the percentage content of total heat expansion microspheres in the adhesion agent layer increases while the viscosity of the adhesion agent is ensured; therefore, the heat stripping effect of the integral polyethylene adhesive tape is greatly improved.
