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.

Abstract

The invention discloses a compound resin material for a cable and a preparation method thereof. The compound resin material for the cable comprises the following formula components in parts by weight: 35-65 parts of resin, 30-90 parts of nanometer and micrometer composite fillers and 1-30 parts of auxiliary agents. The compound resin material for the cable takes the resin as a main material, is endued with the advantages of excellent impact strength, surface scratch resistant capacity, bending strength and electrical insulation property, ageing resistance and high smoothness through the synergetic effect of the nanometer and micrometer composite fillers and the auxiliary agents. By using the preparation method of the compound resin material for the cable, the product can be obtained by only mixing the components in two steps according to a formula and extruding for granulation at appropriate temperature and has the advantages of simple process, material property enhancement and low cost and is suitable for industrialized production, and conditions are easy to control.

Description

technical field [0001] The invention belongs to the technical field of organic polymer materials, and in particular 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 resistance and surface scratch resistance. Generally, the insulating material used for cables is a resin material, which has limited mechanical strength. At present, some people use nano-modified resin materials to change the aggregation state and crystalline form of resin materials, so as to have new properties. While overcoming the contradiction between rigidity and toughness of traditional materials, the comprehensive performance of materials is greatly improved. , such as impact strength. Nanotechnology has gradually attracted people's attention, and the research and development of nanocomposite materials has become a new hot spot. [...
