Abstract

A husk plastic composite comprises a composition including: PVC 10 to 20 wt %; vinyl chloride/vinyl acetate (VC/VAC) copolymer 10 to 30 wt %; styrene-acrylonitrile copolymer (SAN) 1 to 5 wt %; chlorinated polyethylene (CPE) 1 to 5 wt %; rice husk powder 10 to 40 wt %; inorganic filler 10 to 40 wt %; internal lubricant 0.1 to 1 wt %; external lubricant 0.1 to 1 wt %; and heat stabilizer 1 to 5 wt %. The VC/VAC copolymer in the husk plastic composition can allow the composition to be processed by relatively lower processing temperature to save energy consumption, 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 and can reduce the amount of PVC through a large amount of filling additives but still maintain in good product mechanical properties.
