Problems solved by technology

[0004] With the modern development of urban planning, it has become normal for cables to go into the ground. Usually, trenchless construction is used for construction, which has the advantages of no impact on traffic, little damage to the stratum structure, and short construction period. Cables also have higher requirements. Cables need to have higher strength and better toughness, and sheath tubes are commonly used insulation protection sleeves for power cables. Most of the existing sheath tubes are made of polyethylene, polypropylene, polypropylene, etc. Polymer materials such as vinyl chloride match the above requirements for cables, and the sheath tube should also have matching performance, but the performance of the current sheath tube still needs further improvement

Abstract

The invention discloses a PVC (polyvinyl chloride) electric power sheath tube and a preparation method thereof. The PVC electric power sheath tube comprises vinyl resin, polyvinyl chloride, light calcium, silicone rubber, paraffin, plasticizers, stabilizers, antioxidants and flame retardants. The PVC electric power sheath tube and the preparation method thereof have the advantages that the vinyl resin in the PVC electric power sheath tube has high corrosion resistance; the light calcium helps processing and molding, and the processing cost is reduced; high-and-low temperature stability and insulation are enhanced through the silicone rubber; the lubricity is improved through the paraffin; resistance to heat, weather, oxidation, acid, base and fire is improved through the plasticizers, thestabilizers, the antioxidants and the flame retardants, and accordingly, the product stability is ensured; the PVC electric power sheath tube has excellent corrosion resistance, oxidation resistance,heat resistance, weather resistance, acid-alkali resistance and flame resistance, good insulation performance, a smooth surface, a small friction coefficient, high product stability and prolonged service life.

Description

technical field [0001] The invention belongs to the field of PVC pipe production, and in particular relates to a PVC power sheath pipe and a preparation method thereof. Background technique [0002] PVC (polyvinyl chloride) is a non-crystalline multi-component plastic, mainly used in two types: soft (SPVC) and hard (RPVC). The material has non-flammability, high strength, heat resistance, corrosion resistance, etc. performance. PVC hard pipe is made by mixing PVC resin with additives such as stabilizer, lubricant, auxiliary processing agent, colorant, impact resistance agent and other additives. After granulation extrusion molding or one-time extrusion molding, it can replace rubber pipe. For conveying liquids, corrosive media and as cable bushings. Cable protection tube is also known as cable tube, power cable tube, power row tube, power cable protection tube, etc. [0003] The cable protection tube should be installed at the intersection of communication cables and powe...
