Abstract

The invention discloses a shoe sole adhesive. EVA glue is utilized as the shoe sole adhesive, and the EVA glue is prepared from main ingredients of EVA resin, water and n-butyl alcohol which cooperate with hydrolyzed peach gum and modified starch. The prepared adhesive disclosed by the invention has good strength, is convenient to use, avoids volatile toxic matter generation in a producing and use process and achieves safe and environment-friendly effects; when the shoe sole adhesive is applied to the field of shoe sole adhesion, an adhesion strength is not smaller than 3.0KN / m, and the problem that the shoe sole is prone to degumming is avoided; by means of a synergistic effect of adding the hydrolyzed peach gum and the modified starch, the adhesion strength of the adhesive is obviously improved; furthermore, an antibacterial rate of the adhesive is greatly improved, especially an inhibiting effect on trichophyton mentagrophytes is obvious; thus, dermatophytosis generation is avoided, health and safety of feet of a shoe wearer are guaranteed, and comfortableness is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of shoe adhesives, in particular to a shoe sole adhesive. 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. The earliest people invented fur shoes in order to overcome special circumstances and prevent their feet from being uncomfortable or injured. Shoes have developed to the present, and they have formed what they are now. Shoes of various styles and functions can be seen everywhere. Shoes are indispensable daily necessities in human production and life. In the process of social development, due to the increasing number of materials, styles and uses of shoes, the types of shoes have also begun to enrich, but adhesives are indispensable for shoemaking. , The choice of adhesive often becomes a key factor in the ...
