Problems solved by technology

[0002] In the electronics industry, the problem that often occurs is uneven heat dissipation of electronic products, and a series of unsafe factors will appear in the materials or polymers used in the interior under high heat conditions, which will seriously cause explosions or fire accidents. It makes people have higher and higher performance requirements for conductive adhesive materials that are often used for electromagnetic shielding
However, when traditional conductive flame-retardant adhesives are used in the processing of electronic accessories, the wire-wrapped material is easy to open, the adhesion is poor, and the flame-retardant performance and electrical conductivity are not good.

Abstract

The invention provides an electric-conductive flame-retardant adhesive and a preparation method thereof and belongs to the technical field of electricity. The electric-conductive flame-retardant adhesive includes, by weight, 25-38 parts of silicon rubber, 3-8 parts of acrylate rubber, 5-8 parts of inulin biomass charcoal, 3-5 parts of Al(OH)3, 5-10 parts of graphene oxide, and 4-8 parts of a crosslinker. With silicon rubber and acrylate rubber being a matrix, conductivity of the materials is improved by crosslinking with the graphene oxide; by adding the inulin biomass charcoal, which enters the matrix and forms a network-like inner surface with the graphene oxide, thus further improving conductivity of the material. The Al(OH)3 enters the network-like inner surface in the same way, so that the Al(OH)3 and the graphene oxide have synergistic effect. The electric-conductive flame-retardant adhesive has stable performance and is excellent in flame-retardant performance, electric-conductivity and adhesion force. The method is simple and employs the environment-friendly material, biomass charcoal, so that the electric-conductivity of the adhesive is enhanced and the product is environment-friendly.
