Problems solved by technology

At present, the domestic adhesives used for rubber and metal bonding are basically solvent-based adhesives, such as neoprene, styrene-butadiene rubber, etc., but there are few types of water-based adhesives used in this area, and there are no related patents, and solvent-based adhesives are easy to use. Flammable and explosive, the volatilized organic solvent is poisonous, destroys the atmospheric environment, and is very dangerous to people and the environment in the process of production and use, and the solvent will easily cause rubber deformation and affect the appearance of rubber corrosion

Abstract

The invention discloses a water-based adhesive used for the bonding between rubber and metal; according to the parts by weight, the adhesive comprises 60-90 parts of soft monomer, 30-60 parts of hard monomer, 2-8 parts of functional monomer, 3-10 parts of emulsifier, 0.4-0.8 part of initiator, 0.6-1.0 part of pH buffer, 100 parts of deionized water or distilled water, 0.05-0.1 part of anticorrosive bactericide, and 1.4-1.6 parts of pH regulator. The invention also discloses a preparation method for preparing the water-based adhesive. The adhesive can replace the existing solvent-typed adhesive, effectively realizes the bonding between the rubber and the metal, has no poison, no combustion and no explosion, is safe and protects the environment. The preparation method which applies the seed latex polymerization has simple preparation process and high production efficiency and is beneficial for the industrial production.

Description

technical field [0001] The invention relates to a water-based adhesive, in particular to a water-based adhesive used for bonding rubber and metal, and belongs to the technical field of adhesives. Background technique [0002] The bonding of rubber to metal is widely used in industry, such as rubber-metal seals, shock absorbers, transmission belt installation, loudspeakers, various decorations and toys, and many other fields. At present, the domestic adhesives used for rubber and metal bonding are basically solvent-based adhesives, such as neoprene, styrene-butadiene rubber, etc., but there are few types of water-based adhesives used in this area, and there are no related patents, and solvent-based adhesives are easy to use. It is flammable and explosive, and the volatilized organic solvents are poisonous and damage the atmospheric environment. There is a great danger to people and the environment in the process of production and use, and solvents can easily cause rubber defo...
