All-water-based rubber treating agent for shoe making industry

Abstract

The invention discloses a full-water-based rubber treating agent for the shoe making industry. The treating agent the following raw materials in percentage by weight: 95%-99% of deionized water, 0.01%-0.04% of hydrophilic chlorinated rubber resin, 0.01%-0.04% of hydrophilic vinyl chloride-vinyl acetate resin, 0.01%-0.04% of modified organic acid, 0.01%-0.04% of inorganic acid, 0.5%-2% of an organic silicon surfactant, 0.5%-2% of a polysiloxane wetting agent and 0.01%-0.04% of an indicator. Modified aids with high adherence are introduced, the materials are dissolved for 1-2 hours under constant-speed stirring, so that the dispersing performance of the raw materials in polymer emulsion is modified, the surface treatment effect on rubber is improved, a full-water-based system is adopted, the problem of environmental pollution caused by the product is solved, the production cost is reduced, potential production safety hazards are eliminated, the treatment effect on rubber materials is good, and the later tension is greater than 4.5 kg / cm.

Description

technical field [0001] The invention belongs to the technical field of leather preparation, and relates to a fully water-based rubber treatment agent used in the shoemaking industry. Background technique [0002] Rubber is a sole material widely used in the footwear industry. It needs to be pretreated to overcome the influence of material differences and meet the objective requirements for sole bonding. The traditional shoemaking industry uses the cold bonding process to increase the specific surface area of ​​the rubber by removing the weak interface layer on the rubber surface and increasing the roughness, thereby increasing the contact area. There are two traditional surface treatment methods, one is to increase the surface roughness by mechanical grinding, the other is to use acetone and other solvents to wipe the surface after mechanical grinding, and the surface-treated rubber can be bonded by gluing. [0003] The existing technology is mainly to increase the degree o...

Problems solved by technology

[0003] The existing technology is mainly to increase the degree of roughness to achieve the effect of increasing the specific surface area and increasing the contact area. For general rubber surfaces, it is indeed possible to partially increase the bonding degree of the rubber surface by increasing the contact area. However, due to the variety of rubber types There are many kinds of oily solvents in the existing technology products, which pollute the environment and also have the risk of inflammability and explosion. They do not meet the requirements of the existing national policies for reducing the VOC content of oily products, and do not meet the concept of environmental protection.
