Abstract

The invention discloses a low cost environmental protection ultra-tough rigid polyvinyl chloride nano compound capable of injection molding and a preparation method. The raw material of the compound comprises the components by weight parts: 100 parts of polyvinyl chloride, 10 to 100 parts of nano calcium carbonate, 4 to 100 parts of acrylonitrile-butadiene-styrene terpolymer, 1 to 3 parts of lanthanum tin compound stabilizer, 1 to 3 parts of acrylate processing aid, 1 to 3 parts of inner lubricant and 0.3 to 1 part of outer lubricant. The low cost environmental protection ultra-tough rigid polyvinyl chloride nano compound capable of injection molding is obtained after mixing and cooling the raw materials in a high-speed mixer and granulating in a conical twin-screw extruder. In the invention, the advantages of good flame retardance, strong rigidity and low price of polyvinyl chloride resin, strong rigidity, toughening property for polyvinyl chloride and low price of the nano calcium carbonate, impact resistance, low temperature resistance, easy molding and processing and the like of ABS (Acrylonitrile Butadiene Styrene) are integrated; the product has low price, environmental protection performance, ultra-high toughness, good comprehensive mechanical property and good processing fluidity, and has wide application prospect and obvious social benefit in the fields of household appliance elements, automobile instruments and the like.

Description

technical field [0001] The invention relates to a low-cost, environment-friendly and injection-molded super-tough rigid polyvinyl chloride nanocomposite and a preparation method thereof. Background technique [0002] Polyvinyl chloride is one of the commonly used general-purpose plastics. It has the advantages of flame retardancy, high chemical resistance, good mechanical strength and electrical insulation, low price, and wide application fields. At the same time, it also has some disadvantages, such as poor toughness, poor thermal stability, difficult processing, poor flame resistance, etc., which seriously limit its use. [0003] Plastic nanocomposites are a new class of high-performance, functional and specialized materials obtained by physical blending or chemical grafting. Plastic nanocomposite products can be widely used in automobiles, electronics, precision instruments, office equipment, packaging materials, building materials and other fields. It can improve or in...
