Abstract

The invention relates to a preparation method of a high temperature-resistant PVC / ABS / PMMA alloy material, belonging to the technical field of polymer materials. The method includes the following steps: adding PVC, ABS, PMMA, fluororubber, white carbon black, dioctyl phthalate, aluminum stearate, layered silicon thin rock powder, clay, silicon micropowder, and zinc oxide into the mixer, Raise the temperature, stir evenly, and discharge the material to cool; extrude the obtained cooling material with a twin-screw extrusion granulator to obtain granule A; mix granule A with chlorinated polyethylene elastomer and triallyl isocyanate Stir and mix evenly; put the mixture into a single-screw extruder, and hot-melt extrude to obtain. The PVC alloy material provided by the invention still has good wear resistance after high temperature test.

Description

technical field [0001] The invention relates to a preparation method of a high temperature-resistant PVC / ABS / PMMA alloy material, belonging to the technical field of polymer materials. Background technique [0002] Polyvinyl chloride (PVC) is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It is a homopolymer of vinyl chloride. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. PVC is a white powder with an amorphous structure and a small degree of branching. The molecular weight of industrially produced PVC is generally in the range of 50,000 to 120,000, with a large polydispersity, and the molecular weight increases with the decrease of the polymerization temperature; there is no fixed melting point, it starts to soften at 80-85°C, and becomes viscoelastic at 130°C , 160 ~ 180 ℃ began to change into a viscous flow state; good mechanical properties, tensile strength of abo...
