Abstract

The invention relates to a PVC pipe material having high toughness, thermal stability and stainless steel effects, which includes, by weight, 100 parts of PVC, 15-30 parts of stainless steel powder, 8-15 parts of a dispersant, 8-18 parts of crystal whiskers, 5-15 parts of butadiene styrene rubber powder, 1-3 parts of a coupling agent, 1.5-3 parts of a thermal stabilizer, and 0.5-1.5 parts of a lubricant. The PVC pipe material has excellent stainless steel effects, wherein due to the added butadiene styrene rubber powder and crystal whiskers, the PVC pipe material has good toughness, thus avoiding a problem of further reduction of the toughness of the PVC pipe material due to addition of the stainless steel powder. A rare earth stabilizer and a sulfo-ester anti-oxidant are compounded to prepare a thermal stabilizer, so that the PVC pipe material has excellent thermal stability.

Description

technical field [0001] The invention relates to a high-toughness, heat-stable PVC pipe material with stainless steel effect, which belongs to the technical field of PVC pipe preparation. Background technique [0002] Polyvinyl chloride, referred to as PVC, is a polymer formed by polymerization of vinyl chloride monomer in peroxide, azo compound and other initiators or under the action of light and heat according to the mechanism of free radical polymerization.
