Problems solved by technology

[0003] At present, PVC cable materials use two kinds of PVC resins with different polymerization degrees as base materials. Although they meet the requirements of 5G cable materials, materials such as trioctyl trimellitic acid are added, and the cost of product materials is high. The impact resistance of the product is poor, and the yield of the finished product is relatively serious; at the same time, calcium stearate or polyethylene wax is added to the PVC cable material as a lubricant, the extrusion efficiency of the PVC cable material is low, and the PVC cable is extruded The product appearance brightness of the material is poor

Abstract

The invention relates to a high-temperature-resistant low-shrinkage impact-resistant PVC cable material for 5G optical cables. The material is composed of the following components: SG3 type PVC resin,PVC resin with a polymerization degree of 2500, acrylonitrile-butadiene-styrene (ABS), nitrile rubber, 4-phenylethynyl phthalic anhydride, epoxy soybean oil, antimonous oxide, melamine phosphate, a filler, aluminum hydroxide, a calcium-zinc heat stabilizer, an antioxidant 1098, dimethyl benzyl carbinol, alpha-methyl styrene, 5-10 parts of an ethylene-vinyl acetate-maleic anhydride copolymer M506and glass beads. A cable prepared from the PVC cable material can be impacted by an iron hammer at -20 DEG C without cracking, the shrinkage rate is 2% or below, the extrusion speed of the product isincreased, and the lubricating effect and brightness of the PVC cable material are changed.

Description

technical field [0001] The invention relates to an environment-friendly cable material, in particular to a high-temperature-resistant, low-shrinkage, impact-resistant PVC cable material for 5G optical cables and a preparation method thereof. Background technique [0002] The development of mobile communication technology has gone through four stages of development. The first generation (1G) communication technology was proposed in the early 1980s and has experienced ten years of development. Due to its low speed, poor quality, poor security, no The shortcomings of encryption and small business volume were quickly replaced by the second-generation communication technology that adopted a more intensive technical structure and intelligent technology. Although 2G communication technology has improved compared with 1G, it still cannot really meet the needs of mobile communication services. development needs; the advent of the third generation (3G) communication technology, throug...
