Preparation method of hot melt adhesive for shoe material

Abstract

The invention discloses a preparation method of a hot melt adhesive for a shoe material. The preparation method comprises the following steps: firstly, proportioning according to the weight components of each hot melt adhesive and raw materials for the shoe material; adding the raw materials into a container according to a certain proportion, stirring and mixing at normal temperature to obtain a hot melt adhesive, placing base cloth on a cloth rolling machine, coating the surface of a shoe material with the obtained hot melt adhesive and bonding with the base cloth, wherein the hot melt adhesive comprises the following components in parts by mass: 78-91 parts of thermoplastic polyurethane elastomer, 9-22 parts of ethylene-ethyl acetate copolymer, 20-50 parts of ethylene-vinyl acetate copolymer and 8-12 parts of polyethylene polypropylene fibers. According to the shoe material manufacturing technology, secondary gluing is carried out in the shoe material manufacturing technology, the connection firmness of all manufacturing materials of the shoe material can be improved, the shoe material is high in viscosity and resistant to water washing, the shoe material manufactured through the technology can be directly replaced with a solvent type cleaning agent when cloth on the surface is removed, no trace is left on the surface, and non-toxic and environmentally friendly effects are achieved; the application field is very wide.

Description

technical field [0001] The invention relates to the technical field of shoe material preparation, in particular to a method for preparing hot melt adhesive for shoe materials. Background technique [0002] Shoes have a long history of development. About 5,000 years ago in the Yangshao culture period, the most primitive shoes made of animal skins appeared. Shoes are a tool for people to protect their feet from injury. Nowadays, shoes have become a part of people’s daily life. Essential items, currently in the field of shoe materials, hot-melt pressure-sensitive adhesives are mainly used, which are mainly composed of synthetic rubber, resin and rubber oil, etc., heated into a molten state and then coated on tissue paper, cloth or plastic film A kind of adhesive tape made on the substrate, but the shoe material made by this process is not washable, and the hot-melt pressure-sensitive adhesive has a low viscosity, and the surface material will be cracked after long-term use, whi...
