Abstract

The invention relates to a production process for a laminating and coating adhesive film. The production process comprises the following steps: firstly, preparing master match; adopting EMAA (Ethylene Methacrylic Acid) of which a melt index at the temperature of 190DEG C is 0.5 to 5g/10min as a master batch base material, adopting polymeric paraffin as a dispersing agent, and extruding by adopting a twin-screw extruder; secondly, uniformly mixing EVA (Ethylene-Vinyl Acetate) resin with a coupling agent, wherein a melt index of the EVA resin at the temperature of 190DEG C is 5 to 15g/10min; thirdly, generating the laminating and coating adhesive film by adopting a three-layer co-extrusion casting film forming technique, wherein two sides of the laminating and coating adhesive film are EMAA resin, the middle of the laminating and coating adhesive film is the EVA resin, the extrusion temperature of an EMAA screw is 90 to 130DEG C, and the extrusion temperature of an EVA screw is controlled at 60 to 90DEG C; fourthly, carrying out embossing forming; controlling the water temperature of a rubber roller of embossing forming equipment to be 8 to 12DEG C, wherein the rubber roller is made of an integrated silica gel material, the hardness is controlled at 60 to 80A, the grained roughness of the rubber roller is 14 to 18 meshes, the water temperature of a steel roller is controlled at 40 to 50DEG C, and the depth of patterns is 0.06 to 0.15mm.

Description

technical field [0001] The invention relates to a production process of a lamination coated adhesive film. Background technique [0002] Car polishing discs, wool discs, and sponge discs were originally bonded with nylon and wool with hot melt glue and were uncontrollable. Existing lamination coating generally uses hot-melt glue or glue, which is labor-intensive and time-consuming to produce, and the glue coating is uncontrollable. Therefore, it produces a solution that can solve the problems of uneven glue coating, poor control of personnel and cumbersome operation, control the fluidity of raw materials and uncontrollable film formation, and replace glue to solve the lamination of wool, sponge and nylon bonding technology It is especially necessary to apply adhesive film. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present invention provides a production process of lamination coating adhesive film that replace...
