Latex squeegee glue and preparation method thereof

Abstract

The invention discloses latex scrapping mucilage and a preparation method thereof. The latex scrapping mucilage is prepared from raw materials, namely natural latex, accelerant sanding liquid, a thickening agent, sodium borate, and white carbon black (obtained by a vapor phase method). The accelerant sanding liquid can disperse in the natural latex better; the thickening agent improves the concentration of the mucilage so as to prevent mucilage penetration; the sodium borate can improve the stability of the mucilage; the white carbon black (obtained by a vapor phase method) with large specific surface area can be used for improving the viscosity of the latex mucilage, alleviating the permeability of the latex mucilage and reducing the viscosity of a semi-finished product. The latex scraping mucilage can achieve the performance of no mucilage penetration and no color change, and the comprehensive performance of the latex mucilage is improved; the shrinkage of the materials is reduced, and thus the utilization rate of the materials is improved; the qualified rate of the finished product is improved; the quality of a sponge insole is stabilized; the purposes of energy conservation and consumption reduction are achieved; the economic cost is saved; the preparation technology and the operation procedure are simplified; the machining efficiency is improved.

Description

technical field [0001] The invention relates to a material for making squeegee rubber, in particular to a latex squeegee cloth glue for midsole cloth of rubber squeegee shoes and a preparation method thereof. Background technique [0002] The midsole cloth of rubber shoes generally uses natural rubber to masticate first, then knead, and then beat into a slurry scraping cloth. The process is as follows: 1) Sulfur masterbatch slurry preparation, including raw rubber breaking, weighing, and raw rubber plasticizing , mixing and beating sulfur masterbatch mortar; 2) scraping cloth mortar preparation, including raw rubber breaking, weighing, raw rubber plasticizing, mixing, beating and scraping cloth. It can be seen from the above-mentioned technological process and use process that it has five major shortcomings and problems: one is that the capital investment is large, and a large-scale workshop and multiple large-scale rubber machinery and equipment must be used; the other is t...

Problems solved by technology

It can be seen from the above-mentioned technological process and use process that it has five major shortcomings and problems: one is that the capital investment is large, and a large-scale workshop and multiple large-scale rubber machinery and equipment must be used; the other is that the process is complicated and the process is long. The third is high energy consumption, due to the high plasticity requirements of raw rubber, the long plasticizing time, and the long beating time, resulting in large consumption of water, electricity, and steam; the fourth is poor environmental protection, because 120# solvent There is some pollution in the use of gasoline; fifth, the product quality is unstable. During the production process of rubber shoes molding, the midsole cloth and the sponge are not firmly bonded, causing the midsole cloth to be empty, and the loss of secondary waste is large

Because the sponge midsole of rubber shoes is honeycomb-shaped, if water-based latex paste replaces the gasoline glue with macromolecular chains, it will block the honeycomb holes and achieve the purpose of impermeability, but the operation is inconvenient. The pulp needs to be scraped at least twice to achieve the desired effect
