Rubber adhesive is a class of chloroprene, nitrile, butyl silicone rubber, polysulfide and other synthetic rubber or natural rubber as the main material formulated into an adhesive. It has excellent elasticity, suitable for bonding soft or coefficient of thermal expansion of the material is very different.
Rubber adhesives are mainly divided into two categories: structural adhesives and non-structural adhesives. Structural and solvent liquid type and film tape type, they are mostly composite system (except polyurethane rubber). Non-structural rubber adhesives can be divided into two categories of solution-type and emulsion-type, in which the solution-type rubber adhesives (rubber glue) for the main type.
Rubber gum liquid is further divided into non-vulcanized type and vulcanized type. The raw rubber after full plasticizing, directly dissolved in organic solvents, can be made of non-vulcanized rubber adhesive, such as natural rubber, cyclized rubber, recycled rubber, etc., this kind of liquid rubber is inexpensive, but the strength is poor. Vulcanized rubber glue is in the plasticizing of raw rubber after adding vulcanizing agent Li, vulcanization accelerator, reinforcing agent, tackifier, antioxidant and other agents. And after mixing and dissolved in organic solvents and made. This kind of rubber liquid performance is better, so the application range is wider.
