Problems solved by technology

In the past, pasty PVC adhesives, oily or water-based PU, and ethylene-vinyl acetate copolymers were commonly used as adhesives by various manufacturers in the past. However, there are long-term problems of high production costs, harsh production conditions, discharge of three wastes that do not meet environmental protection requirements, and poor hand feeling of the obtained products. Good, water resistance and bond strength are not up to standard and many other defects and deficiencies

Abstract

A modified acrylic ether binder and its production are disclosed. The process is carried out by adding evocating agent into vinyl unsaturated monomer, special functional monomer, emulsifier and deionized water, heating, polymerizing, adding into graft monomer, polymerizing, keeping temperature, cooling, filtering to obtain high-strength water proof resin, adding evocating agent into vinyl unsaturated monomer, emulsifier, colloid protector and deionized water, heating, co-polymerizing, keeping temperature, cooling, filtering to obtain base resin, mixing high-strength resin with base resin, heating, catalyzing, polymer network interpenetrating, secondary process for obtained co-polymer and filtering to obtain final product. It's cheap, convenient, safe and has good effect and no waste discharge.

Description

technical field [0001] The invention relates to an adhesive, especially a modified acrylic adhesive, and also relates to a production method of the modified acrylic adhesive. Background technique [0002] In the artificial leather industry and fabric compounding (fabric and fabric, fabric and foaming material, fabric and non-polar organic film, etc.) The fabric is bonded with various base materials to achieve the reinforcement of artificial leather and to manufacture composite materials endowed with various special properties. In the past, pasty PVC adhesives, oily or water-based PU, and ethylene-vinyl acetate copolymers were commonly used as adhesives by various manufacturers in the past, but there are long-term problems of high production costs, harsh production conditions, discharge of three wastes that do not meet environmental protection requirements, and poor hand feeling of the obtained products. Good, water resistance and bond strength are not up to standard and man...
