Water-proof heat-proof inflaming retarding cable sheath material

Abstract

The invention discloses a water-proof heat-proof inflaming retarding cable sheath material which comprises the following raw materials in parts by weight: 23-25 parts of polyphenyl ether PPO, 5-7 parts of polymethyl methacrylate (PMMA), 15-20 parts of polycarbonate (PC), 5-8 parts of polyvinyl alcohol fiber, 10-12 parts of glass fiber, 8-11 parts of nanocellulose whisker, 4-6 parts of ground calcium carbonate, 9-11 parts of wood powder, 4-6 parts of quartz, 9-11 parts of white carbon black, 3-5 parts of diphenyl phosphate ester, 4-6 parts of melamine phosphate ester, 2-4 parts of calcium stearate, 1-3 parts of barium stearate and 2-3 parts of a titanate coupling agent NDZ-TTS. The water-proof heat-proof inflaming retarding cable sheath material has excellent water-proof performance and heatproof inflaming retarding performance, has higher stretch-proof ability and shock strength, and is suitable for underground cable usage environment.

Description

technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to a water-resistant, heat-resistant and flame-resistant cable sheath material. Background technique [0002] Now cables often need to be buried in the ground, and now the cable sheath must not only have extremely high withstand voltage strength, but also have a high mechanical index, and at the same time have high water resistance, fiber-reinforced plastics are often used as cable sheaths Material. Fiber-reinforced plastics generally refer to reinforced plastics that use unsaturated polyester resin, epoxy resin, or phenolic resin as a matrix and glass fibers or other fiber products as reinforcing materials. Fiber-reinforced plastics have the advantages of being light and hard, non-conductive, high mechanical strength, less recycling, and corrosion-resistant. Due to the different types of resin matrix used in fiber-reinforced plastics, there are also great differenc...

Problems solved by technology

Moreover, when the cable is buried underground, the air often does not flow, resulting in a high ambient temperature, which tends to accumulate heat generated by the cable, resulting in spontaneous combustion of the cable.
