Problems solved by technology

But the tensile strength is only 13.4MPa, the elongation at break is only 240%, and the high temperature resistance is poor; Chinese patent (CN103524946A) discloses a high temperature resistant thermoplastic polyvinyl chloride cable material, including polyvinyl chloride, improved Plasticizer, Plasticizer, Modifier, Flame Retardant, Inorganic Filler, Stabilizer, Processing Aid
It improves the high temperature resistance performance of polyethylene cables by adding rubber modifiers and using trimellitate plasticizers. However, adding too many additives not only increases production costs, but also affects PVC The mechanical properties of ethylene are affected, and trimellitate plasticizers are volatile, which is not conducive to environmental protection

Abstract

The invention discloses a novel environment-friendly high-temperature-resistant polyvinyl chloride cable material comprising the following components in parts by weight: 50-80 parts of polyvinyl chloride resin, 1-5 parts of nano-grade silica, 2-6 parts of BN nano-sheet, 1-3 parts of bisphenol A, 2-5 parts of a plasticizer, 1-8 parts of a stabilizers, and 2-10 parts of other auxiliary agents. The invention also discloses a preparation method of the environment-friendly high-temperature-resistant polyvinyl chloride cable material. The polyvinyl chloride cable material provided by the invention has the advantages of excellent high-temperature resistance, good mechanical performance, good flame-retarding performance, less fuming material during combustion, and good low-temperature resistance. The preparation method is simple. No toxic substance is released during a preparation process. The material and the preparation method are beneficial for environment protection.

Description

Technical field: [0001] The invention relates to the technical field of polymer modification, in particular to a novel environment-friendly high-temperature-resistant polyvinyl chloride cable material. Background technique: [0002] With the rapid development of the economy, wires and cables are widely used in various industries and fields. Polyvinyl chloride (PVC) cable material is low in price and excellent in performance. It has long occupied an important position in the insulation and protection materials of wire and cable. The probability of application in harsh environments. This requires that PVC wire and cable must have good high temperature resistance and other characteristics. However, existing PVC-based cable materials have inherent defects such as poor thermal stability, easy degradation at high temperatures, and easy aging. [0003] Chinese patent (CN103059480A) discloses a high temperature resistant polyvinyl chloride cable material, which includes polyvinyl...
