Abstract

The invention discloses a high-molecular plastic masterbatch and a preparation technology thereof. The high-molecular plastic masterbatch is prepared from, by weight, 70-90 parts of polyvinyl chloride, 6-12 parts of lauryl betaine, 5-15 parts of barium titanate, 12-22 parts of kieselguhr, 2-8 parts of fire-retardant plasticizer, 5-15 parts of white carbon black, 12-26 parts of nano-silica, 2-8 parts of glass fiber, 4-18 parts of nano-titania, 5-10 parts of maleic anhydride and 8-18 parts of silane coupling agent. The preparation technology is simple, and the obtained high-molecular plastic masterbatch has the properties of high strength, high temperature resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation, in particular to a polymer plastic masterbatch and a preparation process thereof. Background technique [0002] Polyvinyl chloride 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 about 60MPa...
