Adhesive for sole of leather shoe and preparation method thereof

Abstract

The invention discloses an adhesive for the sole of a leather shoe and a preparation method thereof. The adhesive comprises the following raw materials by weight: 10 to 30 parts of white glue, 4 to 16 parts of carboxymethylcellulose sodium, 4 to 5 parts of titanium dioxide, 3 to 9 parts of polyoxyethylene, 3 to 9 parts of natural particles, 15 to 25 parts of ultramarine, 3 to 9 parts of potassium chloride, 4 to 8 parts of an osmotic agent JFC, 1 to 9 parts of a dispersing agent, 1 to 3 parts of casein, 3 to 10 parts of a foaming agent, 3 to 9 parts of stearic acid and 30 to 35 parts of soft water. The adhesive for the sole of the leather shoe is low in toxicity and friendly to environment and is an environment-friendly adhesive; and the raw materials of the adhesive are easily available and low in cost. According to the method, the usage amount of macromolecular materials in the adhesive is reduced and the usage amount of natural particles is increased, so shoe material infiltration performance of the adhesive is improved. Since titanium dioxide has good weatherability, the prepared adhesive has stable chemical properties and is not prone to denaturation and viscosity reduction.

Description

technical field [0001] The invention belongs to the field of shoe processing, and in particular relates to a leather shoe sole adhesive and a preparation method thereof. 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. With the development of shoes, 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 rubber is indispensable for shoemaking. Adhesives, most of the current adhesives are still solvent-based ad...

Problems solved by technology

Solvent-based adhesives will be accompanied by a large amount of solvent volatilization during production, construction and curing, causing serious environmental pollution and waste of resources. At the same time, since most organic solvents are harmful to the human body, they will also seriously endanger the health of production personnel.
