A polyvinyl chloride-asphaltene composite and a method of making the polyvinyl chloride-asphaltene composite is disclosed. The composite includes a polyvinyl chloride (PVC) polymer in an amount of 90 to 99.5 wt. %, based on a total weight of the polyvinyl chloride-asphaltene composite, and a filler in an amount of 10 wt. % or less, based on a total weight of the polyvinyl chloride-asphaltene composite. The filler is an asphaltene, the asphaltene is the only filler present, and the asphaltene is uniformly dispersed within a matrix of the PVC polymer. The polyvinyl chloride-asphaltene composite of the present disclosure demonstrates enhanced thermal stability and improved mechanical tensile or thermo-mechanical properties.

A husk plastic composite comprises a composition including: PVC 10˜20 wt %; vinyl chloride/vinyl acetate (VC/VAC) copolymer 10˜30 wt %; styrene-acrylonitrile copolymer (SAN) 1˜5 wt %; chlorinated polyethylene (CPE) 1˜5 wt %; rice husk powder 10˜40 wt %; inorganic filler 10˜40 wt %; internal lubricant 0.1˜1 wt %; external lubricant 0.1˜1 wt %, and heat stabilizer 1˜5 wt %. The VC/VAC copolymer in the husk plastic composition provided by the present invention can allow the composition to be processed by relatively lower processing temperature to save energy consumption. It will also prevent the husk powder from being burnt or decomposed due to high temperature during the heating process to allow this natural material being added in a large amount in the composition. The present invention can reduce the amount of PVC through a large amount of filling additives but still maintain in good product mechanical properties. The particle size of the husk is preferably in the range of 0.10˜0.60 mm for better hardness, stiffness and wood-like texture in the final product.
