Abstract

The invention discloses an aqueous fluororubber emulsion adhesive and a preparation method thereof and belongs to the technical field of adhesive preparation. The aqueous fluororubber emulsion adhesive mainly comprises 95-105 parts of an aqueous fluororubber emulsion, 10-30 parts of an aqueous epoxy resin, 3-9 parts of an amine curing agent, 1-3 parts of an acid-absorbing agent and 0-5 parts of anemulsion film forming aid on the basis of the non-volatile mass. The amine curing agent is a water-soluble or water-dispersible amine curing agent. The acid-absorbing agent comprises one or more of light magnesium oxide, zinc oxide, calcium oxide, calcium hydroxide and corresponding aqueous dispersions. The emulsion film forming aid comprises one or more of ethylene glycol, ethylene glycol butylether, propylene glycol methyl ether, propylene glycol ethyl ether, propylene glycol butyl ether, dipropylene glycol monopropyl ether, N, N-dimethylacetamide and N-methylpyrrolidone. The aqueous fluororubber emulsion adhesive has the strength same to that of the solvent type fluororubber adhesive and VOC content of 1-4%.

Description

technical field [0001] The invention belongs to the technical field of adhesive preparation, and in particular relates to a water-based fluorine rubber emulsion adhesive and a preparation method thereof. Background technique [0002] In recent years, with people's increasingly strong requirements for environmental protection, no volatile organic compounds (VOC) or low VOC systems have become the research direction of new materials. Traditional fluororubber adhesives are made by dissolving fluororubber compound in solvents such as esters and ketones, and adding modifiers such as tackifier resins and curing agents to prepare adhesives with excellent properties such as high temperature resistance, oil resistance, and aging resistance. Adhesives and coating products, these products are widely used in the adhesion between fluorine tape, fluorine tape and anodized aluminum alloy, fluorine tape and chrome-plated steel, glass cloth and anodized aluminum alloy, high silica cloth and ...
