Preparation process of high-modified wear-resistant PVC (polyvinyl chloride) material cable sheath

Abstract

The invention discloses a preparation process of a highly-modified wear-resistant PVC (polyvinyl chloride) cable sheath, and particularly relates to a material technology. Main materials used in the material technology comprise the following raw materials in parts by weight: 50-80 parts of PVC resin, 20-26 parts of EPDM (ethylene-propylene-diene monomer) resin, 40-60 parts of LDPE (low-density polyethylene) resin, 5-10 parts of glass fibers, 5-10 parts of carbon fibers, 3-5 parts of polyester fibers, 3-5 parts of aromatic polyamide fibers and 10-30 parts of polylactic acid. 0.25-0.5 part of a silane coupling agent, 5-10 parts of an inorganic filler, 6-8 parts of activated calcium carbonate, 5-7 parts of a wear-resistant modifier, 3-6 parts of a lubricant, 1-2 parts of a plasticizer and 0.8-1 part of insoluble sulfur. The raw materials in the components are mixed and dispersed more uniformly and meticulously, and the glass fibers, the carbon fibers, the polyester fibers, the aromatic polyamide fibers and the wear-resistant modifier have a synergistic effect, so that the combination effect of PVC and polylactic acid is enhanced, the shape of the material is refined, the flexibility and strength of the material are improved, the wear resistance of the material is also improved, and the service life of the material is prolonged. The heat conductivity of the material is reduced, the material is not easy to age, the appearance design is high in applicability, and the application prospect is better.

Description

technical field [0001] The embodiments of the present invention relate to the field of material technology, and in particular to a preparation process for cable sheaths made of highly modified wear-resistant PVC materials. Background technique [0002] Polyvinyl chloride (PVC) is one of the earliest industrialized and widely used general-purpose thermoplastics. It has the advantages of light weight, high strength, insulation, flame retardancy, corrosion resistance, excellent comprehensive performance, low price and wide source of raw materials. Polymer The edge banding is a thermoplastic coil made of polymer as the main raw material, adding plasticizers, stabilizers, lubricants, dyes and other additives, mixing and pressing together. Its surface has patterns and patterns such as wood grain, marble, cloth grain, etc. At the same time, the surface luster is soft, with a sense of reality and three-dimensionality of wood; it has a certain degree of smoothness and decoration, and...

Problems solved by technology

[0004] To this end, the embodiment of the present invention provides a preparation process for cable sheaths made of highly modified wear-resistant PVC materials, through which the raw materials in the components are mixed and dispersed more uniformly and finely, adding glass fibers, carbon fibers, polyester fibers, and polyaramid fibers The synergistic effect of the wear-resistant modifier enhances the combination effect of PVC and polylactic acid, refines the material shape, not only improves the flexibility and strength of the material, but also improves the wear resistance of the material and reduces the thermal conductivity of the material. High efficiency, not easy to age, strong applicability of appearance design, good application prospect, solves the problem that the wear resistance of PVC material is not good enough due to the addition of various fillers or insufficient preparation technology, which affects the performance of PVC material problem of use
