Problems solved by technology

In addition, in the production process of chloroprene rubber itself, talcum powder is added in order to prevent the dry glue from sticking, and its adhesive products must be added with inorganic substances that are not compatible with solvents such as magnesium oxide and zinc oxide to absorb its release. Chlorine in order to maintain the stability of performance, so the neoprene adhesives have precipitation or even serious delamination

Abstract

The invention provides a midsole adhesive with high solid content and a preparation method thereof. The midsole adhesive with high solid content is prepared from the following raw materials in parts by weight: SBS elastomer: 15-20 parts, methylcyclohexane: 50-60 parts, butanone: 10-15 parts, methyl Methyl acrylate: 10~15 parts, vinyl acetate: 2~5 parts, acrylic acid: 1~2 parts, initiator: 0.2~0.3 parts, terminator: 0.5~1 parts, terpene resin: 10~15 parts, C9 Petroleum resin: 5~10 parts, 138 glycerin resin: 5~10 parts, rosin: 20~30 parts. The midsole adhesive prepared by the invention has high solid content, low VOC content, clear glue solution, good stability, long stickiness maintenance time, low cost, wide source of raw materials, and good application prospect.

Description

technical field [0001] The present invention relates to an adhesive, more specifically, to a midsole adhesive with high solid content and a preparation method thereof. Background technique [0002] At present, the midsole adhesives for shoes on the market are all based on neoprene universal adhesives. Due to the high polarity of neoprene rubber and high solubility requirements, these products use a large amount of excellent solubility. Common triphenyls (toluene, xylene, benzene, etc.), and halogenated hydrocarbon solvents must also be added with phenolic resins to improve heat resistance, but these materials are highly toxic, and some may even cause cancer. Due to the presence of chlorine, phenol, aldehyde, triphenyl and other toxic substances, low solid content, high VOC (volatile organic compound content), and great air pollution, neoprene adhesives are eliminated products in developed countries. In addition, in the production process of chloroprene rubber itself, talcum...
