Abstract

The invention discloses a high-resilience abrasion-resistant cable material which comprises the following raw materials in parts by weight: 2-3 parts of triterpenoid saponin, 6-10 parts of vinyl carboxylic ester, 370-400 parts of silicon rubber, 50-60 parts of carbon nanotubes, 86-90 parts of acrylic acid, 80-100 parts of N,N'-dicyclohexylcarbodiimide, 7-10 parts of 4-dimethylaminopyridine, 300-460 parts of tetrahydrofuran, 1.7-2 parts of a silane coupling agent KH550, 120-150 parts of 65-68wt% sulfuric acid, 100-130 parts of 95-98wt% nitric acid, 30-40 parts of tetraethyl orthosilicate, 2-3 parts of ammonia water, 4-5 parts of 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane, 3-5 parts of polyimide, 1-2 parts of diacetone alcohol, 4-6 parts of propylene glycol alginate, 1-2 parts of calcium alginate, 10-13 parts of chlorinated PVC resin, 3-4 parts of barium petroleum sulfonate and 4-6 parts of an antioxidant DFC-34. The cable material is very high in resilience, strong in anti-compression capability, and high in abrasion resistance.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a wear-resistant cable material with good resilience 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-cont...

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
