Abstract

The invention provides a PVC (polyvinyl chloride) alloy material which comprises a modified PVC composite material filled with active nano calcium carbonate and injection molding grade ABS (acrylonitrile-butadiene-styrene) resin. The PVC alloy material is characterized in that the PVC modified alloy material comprising the following components in percentage by weight: 40-80% of the PVC composite material and 20-60% of the ABS resin, wherein the PVC composite material comprises PVC resin, a thermal stabilizer, a lubricant, an impact modifier, an antioxidant, a flame retardant, and a filling agent namely active anno calcium carbonate. The filling agent, namely active anno calcium carbonate, is added into the components of the PVC alloy material provided by the invention, so that the raw material cost is reduced, and the flexural modulus of the alloy material is improved. ABS greatly improves the fluidity of the alloy material and improves the alloy processability.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a PVC modified alloy material. Background technique [0002] Polyvinyl chloride (PVC) plastic is based on PVC resin, mixed with various additives such as stabilizers, plasticizers, fillers, colorants and modifiers, and processed through plasticization and molding. PVC plastic has good comprehensive mechanical properties and flame retardancy, and the source of raw materials is abundant, and the price is low. It is a general-purpose material with the most superior performance-price ratio. The disadvantage is that the melt viscosity is large. [0003] ABS resin is copolymerized from three monomers of acrylonitrile-butadiene-styrene, which not only maintains the gloss and processing fluidity of polystyrene, but also has the impact resistance of rubber and the rigidity of acrylonitrile, which is very excellent. However, when ABS resin is used in the automotive i...
