The invention discloses an antistatic wood-plastic
composite material and a preparation method thereof. The antistatic wood-plastic
composite material is prepared from the following raw materials in parts by weight: 30 to 60 parts of PVC resin
powder, 10 to 30 parts of
calcium filling agent, 15 to 25 parts of
plant fiber powder, 1 to 5 parts of plasticizing adjusting agent, 1 to 3 parts of
processing additives, 2 to 6 parts of environment-friendly stabilizer, 1 to 3 parts of lubricating agent, 1 to 5 parts of
toughening agent, and 10 to 20 parts of
antistatic agent. The preparation method comprises the following steps:
drying at a high temperature, enabling the
water content to be less than 1 percent, stirring and mixing at high speed at the temperature of 110 to 130 DEG C, adding the treated mixed
powder into an extruder, extruding at the high temperature, calendaring molding, drawing and
cutting and molding, wherein
graphene powder of a
layered structure is uniformly distributed in PVC and forms a netted structure with the PVC, so that the wood-plastic
composite material prepared by the invention is excellent in various mechanical performance and good in antistatic performance, wherein the antistatic performance (
specific resistance) can reach the order magnitude of 106
ohm / sq; and moreover, the whole production process is simple and stable and suitable for industrialized production.
