NOVELTY - Antistatic fire-proof wood-plastic profile, comprises 40-50 pts. wt. wood fiber, 2-4 pts. wt. polyacrylonitrile fiber, 2-4 pts. wt. aluminum silicate fiber, 10-25 pts. wt. high-density polyethylene, 2-4 pts. wt. maleic anhydride grafted high density polyethylene, 3-6 pts. wt. calcium carbonate, 4-8 pts. wt. montmorillonite, 2-6 pts. wt. bentonite, 2-5 pts. wt. lubricant, 0.4-0.8 pt. wt. graphene, 2-4 pts. wt. antistatic agent, 12.5-15.5 pts. wt. flame retardant and 0.5-0.8 pt. wt. silane coupling agent. USE - Used as antistatic fire-proof wood-plastic profile. ADVANTAGE - The antistatic fire-proof wood-plastic profile: utilizes graphene and antistatic agent to modify high-density polyethylene, which can eliminate static electricity generated by friction in the production process of high-density polyethylene, and can greatly improve the antistatic effect of the material; utilizes antistatic component and flame retardant component, which are added separately without mutual influence; and has excellent antistatic performance, flame retardant performance and excellent mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation antistatic fire-proof wood-plastic profile, comprising (1) adding graphene and antistatic agent into high-density polyethylene, and stirring at 85-95℃ for 30-40 minutes to obtain reaction mixture A, placing the reaction mixture A into extrusion granulator, extruding and granulating at 160-190℃ to obtain modified high-density polyethylene granules, (2) pulverizing wood fiber into powder, adding the modified high-density polyethylene particles and the remaining raw materials, and stirring at 80-90℃ for 30-50 minutes to obtain reaction mixture B, placing the reaction mixture B into an extrusion granulator, and extruding and granulating at 135-205℃ to obtain wood-plastic raw material particles, and (3) placing the wood plastic raw material particles into a screw extruder for extrusion molding, where the barrel temperature of screw extruder is 155-175℃, and the screw speed is 55-135 radian/minutes to obtain final product.
