Abstract

The invention discloses an antistatic PVC (Polyvinyl Chloride) pipe. The antistatic PVC pipe is characterized by comprising an antistatic inner layer, an antistatic outer layer and a PVC-M middle layer, wherein the composition of the antistatic inner layer and the antistatic outer layer comprises the following components in parts by weight: 100 parts of PVC resin, 0.8-1.2 parts of a heat stabilizer, 4-8 parts of an impact-resistant modifying agent, 1.3-2.0 parts of a lubricant, 5-10 parts of a processing aid and 6 parts of nano-conductive carbon black; and the composition of the PVC-M middle layer comprises the following components in parts by weight: 100 parts of PVC resin, 1.0-1.5 parts of a heat stabilizer, 10-15 parts of an impact-resistant modifying agent, 2.1-3.5 parts of a lubricant and 1.5 parts of filler. The composition of the antistatic PVC pipe disclosed by the invention has the advantages that the strength is higher, the impact resistance can be comparable with that of a polyethylene antistatic coal mine pipe, the modulus reaches 2231MPa, the tensile strength reaches 46.3MPa, the impact strength value of simply supported beams reaches 97.6MPa, the mechanical property is balanced in rigidity and toughness, the permanent antistatic property is achieved, and the requirements for pipes for coal mines are met.

Description

technical field

[0001] An antistatic PVC pipe belongs to the field of high molecular polymer materials, and in particular relates to a three-layer co-extruded PVC-M pipe structure for coal mines and a composition thereof. Background technique

[0002] With the development and improvement of material synthesis technology, breakthroughs have been made in the research of new materials at home and abroad. People analyze that polyethylene (PE) pipe is a low-strength material, usually in the form of ductile failure, and hard polyvinyl chloride (PE) PVC-U) pipe is a high-strength material, which is often damaged by brittleness. Can a product with both high strength and high toughness be produced to optimize the performance of the product, improve the economy of the product, and develop new technologies? field of application is an important issue. After research, it has been found that the impact-modified PVC (PVC-M) pipe with both strength and toughness can be produced through mat...
