Abstract

The invention relates to a preparation method of a heat-resisting PVC/ABS/PMMA alloy material and belongs to the technical field of high polymer materials. The method comprises the following steps of adding PVC, ABS, PMMA, fluororubber, white carbon black, dioctyl phthalate, aluminum stearate, stratiform silicon flagstone powder, argil, silica powder and zinc oxide into a mixer, increasing the temperature and performing temperature increasing, uniform mixing, discharging and cooling; extruding the obtained cooled materials through a double-screw extrusion granulator to obtain granules A; uniformly mixing and stirring the granules A, chlorinated polyethylene elastomer and trimerical isocyanate triene propyl ester; adding the mixture above into a single-screw extruder, and performing hot-melt extrusion to obtain the heat-resisting PVC/ABS/PMMA alloy material. The hot-melt extrusion to obtain the heat-resisting PVC/ABS/PMMA alloy material still obtains good wear-resisting performance under high-temperature testing.

Description

[0001] technical field [0002] 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. [0003] Background technique [0004] 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, ten...
