Problems solved by technology

The bonding of rubber outsole and EVA midsole is generally bonded with solvent-based neoprene adhesive or polyurethane adhesive. The process of using solvent-based adhesive is complicated, and the rubber outsole and EVA midsole need to be roughened, rinsed with primer, Glue coating, baking solvent, bonding, the process is cumbersome, time-consuming and labor-intensive, and the production cost is high, and the benzene series solvent in the adhesive has caused huge pollution to the environment and seriously endangered the physical and mental health of shoe-making workers
[0003] Although there are also hot-melt adhesive films to bond EVA soles, the process is complicated and time-consuming and consumables

Embodiment

[0030] 1. Hot melt adhesive film:

[0031] As shown in Table 1, nine different hot-melt adhesive films of Examples 1-9 are listed, and the specific components are shown in Table 1.

[0032] Among them, the ratio of raw and auxiliary materials (unit: wt%).

[0033]

[0034] Table 1

[0035] 2. Preparation of hot melt adhesive film:

[0036] (1) Put the main material and auxiliary materials into the mixing device, heat up to 30-100°C, and mix for 30 minutes;

[0037] (2) The twin-screw extruder is heated up to 120 to 180 degrees, and the resulting mixture is extruded and granulated;

[0038] (3) The temperature of the casting machine is raised to 120 to 180 degrees, and the film is formed after casting and extrusion.

[0039] 3. Application of hot melt adhesive film

[0040] Place the hot melt adhesive film made above between the primary foamed EVA layer and the raw film layer to form a three-layer covering structure, then heat the mold to 180°C, then put the above three...

Abstract

The invention discloses a hot melt adhesive membrane which is prepared from antioxidants, petroleum resin and engineering plastics. The invention further discloses a preparation method of the hot melt adhesive membrane and an application of the hot melt adhesive membrane to EVA (ethylene vinyl acetate) pressing rubber sheet forming soles. The hot melt adhesive membrane prepared by the method is low in cost, simple in process and environmentally friendly, and resources are saved.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a hot-melt adhesive film, a preparation method and an application thereof. Background technique [0002] EVA composite sole combines the advantages of wear resistance of rubber, lightness and comfort of foam sole, and has become the most commonly used sole for sports shoes and casual shoes. The bonding of rubber outsole and EVA midsole is generally bonded with solvent-based neoprene adhesive or polyurethane adhesive. The process of using solvent-based adhesive is complicated, and the rubber outsole and EVA midsole need to be roughened, rinsed with primer, Glue coating, baking solvent, and bonding are cumbersome, time-consuming and labor-intensive processes, and the production cost is high, and the benzene-based solvent in the adhesive has caused huge pollution to the environment and seriously endangered the physical and mental health of shoemakers. [0003] Although there are al...
