Abstract

The invention relates to a high temperature-resistant cable for a thermoplastic type car. Two transmission wire cores which are arranged in parallel exist. A spiral wrapping type shielding layer is arranged outside the transmission wire cores. A cable sheath is arranged outside the spiral wrapping type shielding layer. Each transmission wire core is formed by wrapping a thermoplastic type insulating layer around a plurality of copper wire bundles. The raw materials used in the thermoplastic type insulating layer comprise 55-60 weight percent high-polymerization-degree polyvinyl chloride resin, 8-6 weight percent calcium-zinc stabilizer, 28-26 weight percent trimellitic acid mixed ester, 0.6-0.4 weight percent antioxygen, 0.4-0.3 weight percent lubricant, 1-1.3 weight percent methyl methacrylate additives, and 7-6 weight percent calcium carbonate. According to the invention, the temperature classification of 125 DEG C can be achieved; and advantages of good flame retardant performance, good wear resistant performance and good oil resistant performance can be realized.

Description

technical field [0001] The invention relates to a thermoplastic high-temperature-resistant cable for automobiles. The cable has two transmission cores arranged in parallel. A spiral-wrapped shielding layer is arranged outside the transmission cores. set. Background technique [0002] Since the 1990s, the wire and cable industry has become the second largest industry in the machinery industry after the automobile in terms of output value. In 2006, there were more than 6,000 wire and cable enterprises in my country. The industry concentration was low, and the competition for middle and low-end products was fierce, but the supply of high-end products was insufficient, especially thermoplastic PVC insulated wire and cable with high heat resistance. Research and development 125 ℃ grade thermoplastic polyvinyl chloride insulated wire and cable is of great significance for improving the technical level of wire and cable in my country and improving the added value and competitivenes...
