PVC (polyvinyl chloride) power pipeline material and preparation method thereof

Abstract

The invention discloses PVC (polyvinyl chloride) power pipeline material. The PVC power pipeline material comprises, by weight, 100 parts of polyvinyl chloride resin 0.1-0.2mm in particle size, 20-30 parts of calcium carbonate 300-mesh to 700-mesh in particle size, 6-10 parts of impact modifier ACR, 3-6 parts of composite lead salt stabilizer, 0.5-2 parts of lubricant oxidized polyethylene wax, and 4-10 parts of nano-scale inorganic flame retardant. The PVC power pipeline material is high in flame retardancy with oxygen index up to more than 40. PVC power pipelines of the power pipeline material is high in rigidity, heat resistance and ageing resistance, low in manufacturing cost and simple in processing technique.

Description

technical field [0001] The invention belongs to the technical field of polyvinyl chloride composite materials, in particular relates to a PVC power pipe material, and also relates to a preparation method of the power pipe. Background technique [0002] The threading pipe is a hard rubber pipe for electrical installation and wiring, including PVC and PE threading pipes. The threading pipe needs to meet the requirements of anti-corrosion, anti-leakage and flame retardancy. The formula of PVC plastic pipe is mainly composed of PVC resin and additives, among which additives are divided into heat stabilizers, lubricants, processing modifiers, impact modifiers, fillers, anti-aging agents, colorants, etc. . [0003] The threading pipes that are often used in construction have higher requirements for flame retardancy because they are used to install wires. At present, the standard for flame-retardant line pipe is mainly the national quality standard GB8624-2006. Threading pipes c...
