Problems solved by technology

At present, although PVC wires and cables will not be eliminated immediately abroad, this cannot but arouse the great attention of the domestic wire and cable industry. The country should pay attention to the research of non-leaded PVC or the development of new halogen-free environmentally friendly wires and cables.

Abstract

The invention relates to a high-fluidity PVC (polyvinyl chloride) sheath material which consists of the following components: 100 parts of PVC resin, 5-10 parts of calcium-zinc composite stabilizer, 45-55 parts of plasticizer, 30-60 parts of filler, 1.5-3 parts of lubricant, 1.5-2.5 parts of processing aid and 3.5-4.5 parts of pigment. According to the high-fluidity PVC sheath material provided by the invention, the environmental protection performance is guaranteed by the calcium-zinc composite stabilizer, the processing fluidity is improved by combining functional modifiers CA-08 and ACR 401, and the formula cost is reduced through the co-plasticization of low-cost epoxidized soybean oil and dioctyl terephthalate. The environmental protection performance of the PVC sheath material meets the requirements of the ROHS standard, and the general performance meets the HI-90 type index requirements in GB / T 8815-2008 of the standard Flexible PVC Plastics for Wires and Cables.

Description

technical field [0001] The invention relates to a sheath grade soft PVC plastic used for cables, in particular to a high fluidity PVC sheath material. Background technique [0002] Among the insulation and sheath materials of wire and cable, PVC is relatively cheap, has excellent mechanical properties and is easy to process, making it the most widely used material in the wire and cable industry for a long time. Since the end of the 20th century, the environmental problems of PVC materials have been widely recognized, and some developed countries have put forward legal proposals to restrict or completely ban the use of PVC cables. Statistics show that the amount of PVC used in the cable industry in Western European countries was 441kt in 1994, accounting for 58% of the resin used in cables. In 2000, the total amount of PVC used in the cable industry in Western Europe was 398kt, accounting for 50% of the resin used in cables. 48%, both the total amount and the proportion show...
