Abstract

The invention relates to a PVC alloy material and a preparation method and application thereof. The PVC alloy material comprises PVC resin, ABS resin, a stabilizer, a flexibilizer, calcium carbonate, a lubricant and other auxiliaries. According to the PVC alloy material provided by the invention, the calcium carbonate with a specific particle size is taken as a filling agent, and the chloroethyl acrylate-butadiene copolymer with a specific ratio is taken as a toughening agent. Through synergistic cooperation of the calcium carbonate and the copolymer, the weld mark strength of the material can be greatly improved while the impact strength of the PVC / ABS alloy material is basically not reduced, and the alloy material can be widely applied to thin-wall multi-screw-hole security and protection, electrician and electric appliance products.

Description

technical field [0001] The invention belongs to the technical field of modified plastics, and in particular relates to a PVC alloy material and its preparation method and application. Background technique [0002] PVC is a general-purpose plastic with high output and wide application. It has the advantages of flame retardant, high rigidity, corrosion resistance, and low price. It also has the disadvantages of poor thermal stability and brittleness. The alloy material made of ABS modified PVC has excellent mechanical strength. , improve the brittleness of PVC and increase the heat distortion temperature of PVC, and expand the application field of PVC, but it cannot change the fact that PVC / ABS alloy is still a heat-sensitive material, and the melt viscosity of PVC / ABS alloy is relatively high. Poor, molding process often needs to be injected under medium and low speed conditions. For products with multiple gates or many screw holes, due to the insufficient strength of the wel...
