Abstract

The invention provides a waterproof cold resistance temperature resistance inflaming retarding polyvinyl chloride insulating material, which comprises the following components according to the parts by weight mixture ratio: 100 of polyvinyl chloride resin, 20-70 of thermal stability plasticizer, 1-7 of cold tolerance plasticizer, 5-15 of modifier, 3-9 of stabilizing agent, 4-30 of flame retardant, 5-70 of filling agent, and 0.5-3.5 of lubricant. The insulating material has excellent waterproof performance, temperature resistant cold resistance and insulating performance, also has good soft performance and good processing performance.

Description

【Technical field】 [0001] The invention relates to an insulating material, in particular to a waterproof, cold-resistant, temperature-resistant and flame-retardant polyvinyl chloride insulating material. 【Background technique】 [0002] Soft polyvinyl chloride plastic has good physical, mechanical and electrical properties, and is suitable for insulation and sheathing materials for low-voltage wires and cables, as well as electrical accessories. In special occasions, there will be higher waterproof requirements for wires and cables. For example, UL1581 and UL62 require outdoor wires and cables to have very high waterproof performance. For example, SJTW18AWG type wires not only require AC1500V / 1 minute withstand voltage In the test, the insulator does not break, and the wire sample should be placed in 15°C water for more than 6 hours, and its insulation resistance should be tested by DC600V voltage. It is required that the insulation resistance of the 2-core wire should reach 5...
