Abstract

The invention discloses a low-temperature-resistant high impact PVC (polyvinyl chloride) tubular product and a preparation method thereof. The low-temperature-resistant high impact PVC tubular product is prepared from the following raw materials in parts by weight: 38-54 parts of SG-7 type PVC resin, 22-36 parts of ACS resin, 10-15 parts of polyurethane thermoplastic elastomer, 11-17 parts of graphite, 6-9 parts of polytetrafluoroethylene micro powder, 12-16 parts of carbon nanofibers, 10-15 parts of tetraethylene glycol diheptylate, 8-12 parts of glycerol trioleate, 4-6 parts of oxidized polyethlene wax, 5-10 parts of dioctyl azelate, 10-15 parts of triethylene glycol di-2-ethylhexoate, 3-5 parts of ethylene bis stearamide, 14-18 parts of aluminum powder, 15-20 parts of fumed silica, 5-10 parts of sludge dry powder, 10-15 parts of pelelith powder, 2-3 parts of lead cyanurate, 1-2 parts of a calcium-zinc composite stabilizer, 10-15 parts of composite nano powder, 1.5-2.5 parts of tri(sulfydryl ethyl ester stearate) antimony, 1-2 parts of an antioxidant 1035, and 1-2 parts of an antioxidant 168. The PVC tubular product has the characteristics of low temperature resistance, high impact strength and high toughness; on the premise of the high impact strength, the low-temperature resistance and the toughness of the PVC tubular product are greatly improved, so that the tubular product can be normally used for a long time at (-)50 DEG C, and thus, the service life of the PVC tubular product is prolonged.

Description

technical field [0001] The invention relates to a PVC material and a preparation method thereof, in particular to a low-temperature-resistant high-impact PVC pipe and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) has excellent comprehensive properties such as flame retardancy, insulation, corrosion resistance, high strength and low price, and is widely used to make plastic pipes. In recent years, with the rapid development of science and technology, the performance requirements of PVC pipes are getting higher and higher. At present, PVC pipes on the market have the disadvantage of poor low-temperature impact toughness. Long-term use is prone to low-temperature embrittlement and cracking, which greatly reduces its service life. Therefore, it is urgent to develop a low-temperature-resistant and high-impact PVC pipe to meet the market demand. Require. Contents of the invention [0003] The purpose of the present invention is to provide...
