Problems solved by technology

The material of the traditional film is insufficient in terms of toughness, hardness and elasticity, and the process of bonding with the upper requires manual glue application, which is not conducive to automatic production. At the same time, the use of glue also has environmental pollution problems.

Abstract

The invention discloses a shoe material hot-melt adhesive sheet. The shoe material hot-melt adhesive sheet comprises the following raw material components: 35-40% of elastomer, 45-50% of engineering plastic, 10-15% of EVA (ethylene vinyl acetate) binding masterbatch and 0.5-1.5% of antioxidant. A production process of the shoe material hot-melt adhesive sheet provided by the invention comprises the steps of mixing the elastomer, the EVA binder masterbatch, the engineering plastic and the antioxidant in a twin-screw extruder, pressurizing a melt by a melt pump, then enabling the melt to flow out of a T-shaped die head, hot-bonding double surfaces of polyester non-woven mesh fabric on the upper surface and lower surface of the melt of the sheet in a three-roller calendering machine, further calendering and shaping, cooling and shaping the sheet by a cooling roller cylinder after shaping, cutting edges, and then rolling or cutting according to a fixed size. The elastomer hot-melt adhesive sheet can be used for manufacturing finished products of shoe heads and back liners after being stamped by a mold, the shaped adhesive sheet finished products are placed into shoe inner liners and interlayers of shoe vamps for hot-pressing, binding and solidifying, and the production process flow is simplified and is suitable for mass production of an assembly line.

Description

technical field [0001] The invention relates to a shoe material hot-melt adhesive sheet, a production process and equipment. Background technique [0002] As an important part of footwear products, the hot-melt adhesive sheet used for the front lining of the toe cap and the back lining of the heel is to protect the toe and heel from overturning and causing sports injuries. If the sports shoes do not have toe and heel guards, when doing lateral movements, the shoes will prevent lateral sliding due to the anti-slip effect of the soles, and the feet will slide sideways with the inertial force due to lack of support, and excessive sliding is easy Sports injuries such as ankle sprains. The film also plays a role in fixing the shape of the toe and heel of the upper. The material of the traditional film is insufficient in terms of toughness, hardness and elasticity, and the process of bonding with the upper requires manual glue application, which is not conducive to automatic pro...
