Description

technical field [0001] The invention relates to the technical field of cables, in particular to a polymer silicone 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 group...

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
