Abstract

The invention relates to a vulcanize-crosslinked halogenated trans-butadiene and isoprene copolymer rubber adhesive and a preparation method thereof. The adhesive adopts a halogenated trans-butadieneand isoprene copolymer rubber containing 45-82.5% of halide as a matrix, and the formula of the adhesive comprises 100 parts of the halogenated trans-butadiene and isoprene copolymer rubber, 0.1-5 parts of an anti-aging agent, 100-500 parts of a solvent, 0-100 parts of an assistant, 0.5-5 parts of a crosslinking agent, 0-5 parts of a promoter and 0-5 parts of an anti-ultraviolet agent. The adhesive can be used for bonding organic materials, bonding organic materials and inorganic materials and bonding inorganic materials. Double bonds in the halogenated trans-butadiene and isoprene copolymer rubber participate in the vulcanization of the rubber matrix in order to enhance the adhesion of the bonded matrix.

Description

technical field [0001] The invention relates to a formula of a rubber adhesive, in particular to a halogenated trans-butadiene-isoprene copolymer rubber adhesive capable of vulcanization and crosslinking. The invention belongs to the field of formulation, preparation and application of rubber adhesives. Background technique [0002] Rubber adhesive, usually rubber, such as neoprene rubber, nitrile rubber, butyl rubber, acrylic rubber, polyurethane, silicone rubber and other synthetic rubber, is dissolved in an appropriate solvent to prepare an adhesive . This type of adhesive has toughness and elasticity, which is very suitable for bonding polymer to polymer, polymer and other substrates. Chinese invention patent CN200910118594 discloses a polyacrylate rubber adhesive, which is cured by adding an isocyanate-based crosslinking agent. CN201580002113 discloses a thermally curable polyurethane rubber adhesive. Neoprene is the earliest material used in the adhesive industry. ...
