Green rubber slurry for rubber shoe wrapping sponge adhesion, preparation method and applications thereof

Abstract

The invention discloses a green rubber slurry for rubber shoe wrapping sponge adhesion, a preparation method and applications thereof, wherein the preparation raw materials comprise a natural rubber, sulfur, an accelerator, zinc carbonate, stearic acid, rosin, a Y-8804 yellow rubber master batch, a R-8818 red rubber master batch, a G-2210 green rubber master batch, and 120 # gasoline. According to the present invention, the cross-linking stress of the product is increased, it is ensured that the adhesion stress is greater than the compression resilience of the polyurethane foam and the bending rebound force of the composite shoe throat cloth, the cross-linking shaping speed of the rubber slurry is increased, and it is ensured that the composite shoe throat cloth is tightly fixed on the shoe upper lining cloth; with the application of the wrapping sponge to adhere the shoe throat cloth and the counter, the problem that the inaccurate shoe throat cloth positioning and the non-unified pressing loosening of the wrapping sponge cause the non-unified appearance quality of the rubber shoe rear shoe throat during the sewing process of the shoe throat cloth and the counter is solved, and the shoe upper shoe throat wrapping sponge sewing speed and the production efficiency can be substantially improved; and after the adhesion rubber slurry is used, the rubber shoe throat wrapping sponge repair rate is reduced to 0 from the original 5%, and the production efficiency is increased by 15%.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a green rubber paste for bonding rubber shoe bag sponges and a preparation method and application thereof. Background technique [0002] In the style design process of rubber shoes, in order to achieve the problem of wearing the rubber shoes on the heel, keeping warm and preventing cold, a type of rubber shoes adopts green composite cloth for the heel opening (generally polyester filament warp-knitted mesh fabric / polyurethane sponge composite material)” The lining is a certain thickness of natural polyurethane foam (conventional pattern, the maximum thickness of natural polyurethane foam is about 15mm, and the specific gravity is about 0.3). This sewing method is commonly known as rubber shoes sewing mouth bag sponge. [0003] During the operation process of wrapping the rubber shoes with sponge, due to the certain elasticity of the polyurethane foam, the positioning and sewing...

AI Technical Summary

Problems solved by technology

[0003] During the operation process of wrapping sponge on the upper of rubber shoes, due to the certain elasticity of polyurethane foam, the positioning and sewing of the composite cloth and the back of the rubber shoes will be deviated, which will affect the appearance quality, wearing comfort and production efficiency of the rubber shoes heel

[0004] In order to improve the production efficiency, improve the appearance quality and accurate positioning of the rubber shoe top bag sponge, it is necessary to position and bond the composite bottom cloth to the corresponding part of the back side before sewing, so a kind of bag sponge adhesive is needed. In order to overcome the quality problems in the bag sponge operation
