Hot melt adhesive for shoe material, preparation method, shoe material applying hot melt adhesive and shoe material manufacturing method

Abstract

The invention discloses a hot melt adhesive for a shoe material, a preparation method, the shoe material applying the hot melt adhesive and a shoe material manufacturing method. The hot melt adhesivefor the shoe material is prepared from the following components in parts by weight: 80 to 90 parts of thermoplastic polyurethane elastomer and 10 to 20 parts of ethylene-ethyl acetate copolymer. The preparation method of the hot melt adhesive for the shoe material comprises the following steps: weighing the components according to the proportion of the hot melt adhesive for the shoe material; stirring the components at normal temperature; and heating the stirred mixture to 160-170 DEG C. The components of the hot melt adhesive for the shoe material are environmentally friendly, and the hot melt adhesive does not contain formaldehyde, azo, lead, phthalate and other substances and reaches related standards of new European standards. According to the manufacturing method of the shoe material,hot pressing and stitching are not needed, the process is simple, the defective rate is low, the production cost including manual salary, electric charge and the like is greatly reduced, and the production efficiency is high.

Description

technical field [0001] The invention relates to the field of polymer adhesives, in particular to a hot melt adhesive for shoe materials, a preparation method, a shoe material using the same, and a shoe material manufacturing method. Background technique [0002] As a product with good adhesion and high cost performance, hot melt adhesives are widely used in various fields, especially in the field of shoe materials. They are mainly used for plasticity, shaping and bonding of shoes. [0003] At present, 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., mixed and heated into a molten state, and then coated on substrates such as tissue paper, cloth or plastic film. And a kind of adhesive tape of making, when it is used on shoes, need just can play firm bonding effect by hot pressing or sewing thread, and procedure is more complicated, and bonding force is not strong en...

Problems solved by technology

[0003] At present, 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., mixed and heated into a molten state, and then coated on substrates such as tissue paper, cloth or plastic film. And a kind of adhesive tape made, when it is used on shoes, it needs hot pressing or threading to play a firm bonding effect, the process is more complicated, and the bonding force is not strong enough, and it is easy to fall off when exposed to water
