Problems solved by technology

[0004] However, the extrusion speed of radiation cross-linked polyolefin materials and thermoplastic polypropylene materials is slow, and the production efficiency is not high, and the use of radiation cross-linked polyolefin materials needs to be irradiated after the wires are made to reach 125°C. Grade, high cost and back-and-forth transportation affects lead time

Abstract

The invention relates to the field of an insulating material for a cable, and particularly relates to a polyvinyl chloride (PVC) insulating material for a 125 DEG C resistant grade automotive wire and a preparation method thereof. The PVC insulating material for the 125 DEG C resistant grade automotive wire disclosed by the invention comprises the following components in parts by weight: 100 parts of PVC resin, 35-65 parts of plasticizers, 5-10 parts of calcined clay, 5-15 parts of calcium carbonate, 8-15 parts of heat stabilizers, 1-4 parts of lubricants, and 0.5-2 parts of copper anti-oxidants. The PVC insulating material for the 125 DEG C resistant grade automotive wire disclosed by the invention can meet the wire standards of a plurality of automobile manufacturers, is free of special production equipment, high in production efficiency, and low in price, can achieve the grade requirements of 125 DEG C without the processes such as irradiation after the wire is prepared, and is a great advance in development of the automobile industry.

Description

technical field [0001] The invention relates to the field of cable insulating materials, in particular to a PVC insulating material for 125°C-resistant automobile wires and a preparation method thereof. Background technique [0002] As one of the pillar industries of the global economy, the automobile industry has developed rapidly in recent years, especially with the rapid growth of China's economy, the improvement of people's living standards, the focus of consumption has shifted to large housing and automobiles, and domestic policies encourage and support the development of the automobile industry , making the automobile industry flourish. [0003] The wires used in automobiles are an important part of them, and automobile wires have strict requirements on their extrusion process, performance, and use environment. Different countries and automobile manufacturers have their own standards for the wires they use, so they need to be prepared according to different standards. ...
