Problems solved by technology

[0003] At present, there is technology to mix and refine nano-scale fillers and resins to produce insulating materials for cables, but the proportion of coupling agents added is relatively high, which pushes up production costs on the one hand, and on the other hand, the mixing of coupling agents and inorganic fillers is not sufficient and easy Causes agglomeration of nanofillers, which affects the strength of the polymer
There is another technology that completely eliminates the use of coupling agents. At the same time, in order to prevent the mutual polymerization of nano-fillers, the amount of nano-fillers added is relatively low, up to 30%, which fails to give full play to the excellent performance of nano-fillers.
[0004] None of the above technologies comprehensively considered various factors such as the selection of nano-scale and micro-scale inorganic fillers, matrix polymer materials, and surface treatment methods to improve the performance and cost advantages of composite polymer materials.

Description

technical field [0001] The invention belongs to the technical field of organic polymer materials, and particularly relates to a composite resin material for cables and a preparation method thereof. Background technique [0002] Cables are usually buried underground, and the insulating material on the surface needs to have strong impact strength and surface scratch resistance. Usually, the insulating material for cables is resin material, which has limited mechanical strength. At present, some people use nano-modified resin materials to change the aggregation state and crystalline morphology of the resin materials, so as to have new properties, which greatly improves the overall performance of the materials while overcoming the incompatibility between the rigidity and toughness of traditional materials. , such as impact strength. Nanotechnology has gradually attracted people's attention, and the research and development of nanocomposite materials has also become a new hot s...
