Abstract

The invention belongs to the technical field of high polymer materials, and particularly discloses a composite sole hot melt adhesive film and a preparation method thereof. The composite sole hot meltadhesive film is prepared from the following raw materials in parts by weight: 40-50 parts of ethylene-vinyl acetate copolymer, 5-15 parts of thermoplastic elastomer, 20-30 parts of polybutadiene polyurethane, 2-10 parts of ethylene terpolymer, 5-15 parts of tackifying resin, 3-10 parts of reinforcing filler, 3-8 parts of wax and 0.1-1 part of antioxidant. The composite sole hot melt adhesive film is used for bonding an outsole and a mid-low sole of a shoe material, only needs to be attached to the outsole and the mid-low sole for hot pressing when used, and has the advantages of being easy to operate, firm in bonding, durable, non-toxic, environmentally friendly, high in yield and the like. The preparation process of the composite sole hot melt adhesive film is simple, convenient to operate and convenient for mass production.

Description

technical field [0001] The invention relates to the technical field of shoe materials, in particular to a hot melt adhesive film for composite shoe soles and a preparation method thereof. Background technique [0002] At present, most of the production process of the sole is to bond the outsole and the middle and bottom with liquid glue, and the liquid glue used is usually solvent-based polyurethane or polyurethane glue. The liquid glue bonding process includes the steps of roughening the outsole and midsole, brushing low-coating agent, gluing, drying agent, bonding and other steps. The disadvantages of this process mainly include: 1. The production process is complicated and consumes Time-consuming, labor-intensive, high cost; 2. Manual glue is easy to spread unevenly, and the glue is easy to be mixed with air, and the bonding effect is poor; 3. The volatilization of organic solvents in the glue will cause great harm to the human body and the environment, and is not environ...
