Multifunctional aqueous adhesive and preparation method thereof

Abstract

The invention discloses a multipurpose aqueous adhesive, which comprises the following parts: 10-35% thermoplastic rubber or emulsion, 0. 5-35% solvent, 28-45% emulsion, 20-80% viscosifying resin or its emulsion, 0. 5-5% functional adjuvant and 1-20% water. The making method comprises the following steps: putting the solvent into autoclave; stirring at middle speed and adding thermoplastic rubber and its modifying product until dissolving completely; or putting into copolymerized rubber emulsion directly; stirring to add the viscosifying resin or the viscosifying resin in the invention; blending evenly; adding emulsion; fetching the sample to test the viscosity; adding fitful quantity of water and corresponding functional adjuvant according to the purpose and viscosity; dispersing at high speed until even condition; cooling; filtering; packing; obtaining the product for shoe-making, hand pocket and decorative aspect with low cost.

Description

technical field [0001] The invention relates to an adhesive, in particular to a water-based adhesive used for leather bonding, cloth bonding, furniture production, decorative material bonding, and the like in the production of shoes and handbags and bags. Background technique [0002] After years of accumulation and development, especially in the 1990s, my country's shoemaking and handbag industry has grown rapidly. China produced 7 billion pairs of shoes last year, which is equivalent to making a pair of shoes for everyone in the world. China's shoe-making production accounts for 52% of the global output, and it is the world's largest shoe-making country. The output and export volume of footwear products have ranked first in the world. First of all, from the perspective of production capacity and production quantity, there are more than 20,000 shoe-making enterprises in my country, with more than 2 million employees. From the perspective of consumption quantity and marke...

Problems solved by technology

[0004] The purpose of the present invention is to provide a water-based adhesive to solve the above-mentioned deficiencies, which can solve the problems of insufficient adhesive force, harmfulness of solvents, and inflammable and explosive adhesives in solvent-based adhesives for bonding shoes, handbags, bags, and decoration materials. Sex, and avoid the high price of water-based polyurethane and water-based neoprene, which leads to the problem that water-based adhesives cannot be popularized in large quantities, and avoid the problem that hot-melt adhesives cannot be widely popularized due to equipment investment and unsuitability for manual operation.
