Abstract

The invention discloses an aqueous adhesive of shoe and manufacturing method in the shoe adhesive domain, which comprises the following parts: 8-20% polyacrylacid ester emulsion, 75-90% aqueous polyurethane emulsion, 0-3% acetone and 0.2-1% thickener, wherein the polyacrylacid ester emulsion is composed of butyl acrylate, methyl methacrylate, acrylic acid isooctanoic ester, ethyl acrylate, acrylic acid, emulsifier, buffer, reducer and initiator. The manufacturing method comprises the following steps: emulsifying; prepolymerizing; polymerizing; neutralizing; blending.

Description

Technical field: [0001] The invention belongs to the field of adhesives for shoes, and in particular relates to a water-based adhesive used in the shoemaking industry and a production method thereof. Background technique: [0002] There are billions of people in the world, and everyone needs to wear shoes. China has 1.3 billion people. It is the country with the largest number of people who wear shoes in the world, and it is also the largest country in the shoe industry. There are more than 20,000 shoe-making enterprises in my country. At home, most manufacturers use adhesives to produce shoes. Adhesives are mainly divided into two categories: solvent-based shoe glue and water-based shoe glue. The annual consumption of shoe adhesives reaches more than 200,000 tons, but most of them are solvent-based shoe glues. With the increasing awareness of environmental protection, relevant laws and regulations will become increasingly stringent. Water-based shoe glues that do not pollute...
