Carbonized silicone rubber cable material and preparation method thereof

Abstract

The invention discloses a carbonized silicone rubber cable material. The cable material comprises the following raw materials in parts by weight: 370-400 parts of a silicone rubber, 50-60 parts of a carbon nanotube, 80-90 parts of acrylic acid, 80-100 parts of N,N'-dicyclohexylcarbodiimide, 7-10 parts of 4-dimethylaminopyridine, 300-460 parts of tetrahydrofuran, 1.3-2 parts of a silane coupling agent KH550, 120-150 parts of 65-68wt% sulfuric acid, 100-130 parts of 95-98wt% nitric acid, 2-4 parts of ethyl cellulose ethoce, 0.8-1 parts of chlorcosane, 8-10 parts of methylbenzene, 30-40 parts of ethyl orthosilicate, 2-3 parts of ammoniacal liquor, and 4-5 parts of 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane. The carbonized raw materials are compounded with silicone rubber to obtain the carbon-silicon composite material, and the composite material has good hardness and surface strength, and better resistance.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a silicon carbide rubber cable material and a preparation method thereof. Background technique [0002] Since carbon nanotubes can improve the mechanical properties, electrical properties and other properties of composite materials, carbon nanotube / rubber composites have attracted more and more attention. In order to achieve the purpose of enhancement, there are two problems to be solved: one is the dispersion of carbon nanotubes, and the other is the interface between carbon nanotubes and the matrix. Since the surface of carbon nanotubes is relatively inert and the specific surface area is relatively large, it is easy to cause agglomeration. Therefore, the effect of carbon nanotube-reinforced polymers is not very obvious." For this reason, many people began to physically or chemically treat carbon nanotubes. Among these methods, acid treatment to generate oxygen-containing groups...

In order to achieve the purpose of enhancement, there are two problems to be solved: one is the dispersion of carbon nanotubes, and the other is the interface between carbon nanotubes and the matrix. Since the surface of carbon nanotubes is relatively inert and the specific surface area is relatively large, it is easy to cause agglomeration. Therefore, the effect of carbon nanotube-reinforced polymers is not very obvious." For this reason, many people began to physically or chemically treat carbon nanotubes. Among these methods, acid treatment to generate oxygen-containing groups is a common and efficient method. Yes, because it can provide effective / reactive sites to chemically bond with the matrix resin "However, in most cases, this method tends to produce too few groups to provide sufficient linkage to the matrix" so , in order to increase the number of reaction points, it is necessary to introduce more functional groups to interact with the matrix resin
