▎ 摘　　要

NOVELTY - A wood fiber toughened PVC vehicle interior material comprises 40-78 pts. wt. PVC, 25-38 pts. wt. hemp fiber, 25-38 pts. wt. modified lignocellulose, 25-38 pts. wt. graphene, 12-28 pts. wt. slag mineral wool, 12-28 pts. wt. hydroxyethyl methyl cellulose ether, 12-28 pts. wt. basalt fiber, 12-28 pts. wt. zeolite powder, 12-28 pts. wt. 3-aminopropyl triethoxysilane, 1-8 pts. wt. nano-zirconia, 1-8 pts. wt. barium titanate, 1-8 pts. wt. flame retardant, 1-8 pts. wt. erucic acid amide and 1-8 pts. wt. styrene-acrylic latex. USE - Wood fiber toughened PVC vehicle interior material (claimed). ADVANTAGE - The lightweight vehicle interior material is safe and environmentally-friendly, and has high toughness and high strength. DETAILED DESCRIPTION - A wood fiber toughened PVC vehicle interior material comprises 40-78 pts. wt. PVC, 25-38 pts. wt. hemp fiber, 25-38 pts. wt. modified lignocellulose, 25-38 pts. wt. graphene, 12-28 pts. wt. slag mineral wool, 12-28 pts. wt. hydroxyethyl methyl cellulose ether, 12-28 pts. wt. basalt fiber, 12-28 pts. wt. zeolite powder, 12-28 pts. wt. 3-aminopropyl triethoxysilane, 1-8 pts. wt. nano-zirconia, 1-8 pts. wt. barium titanate, 1-8 pts. wt. flame retardant, 1-8 pts. wt. erucic acid amide and 1-8 pts. wt. styrene-acrylic latex. The interior material is prepared by taking 12 pts. wt. modified lignocellulose, drying lignocellulose for 2 hours at 68 degrees C, adding 1 pt. wt. reactive polysiloxane, 1 pt. wt. polystyrene beads, zirconium silicate and 1 pt. wt. nano-silica, grinding, mixing, adding the mixture to 25 pts. wt. dimethylformamide (DMF), stirring, adding 1 pt. wt. epichlorohydrin, heating at 88 degrees C for 1 hour, filtering, washing, adding to 25 pts. wt. water, adding 1 pt. wt. lanthanum nitrate, reacting at 47 degrees C for 1 hour and washing. An INDEPENDENT CLAIM is included for the preparation method of vehicle interior material, which involves adding the raw materials, drying in vacuum at 35 degrees C for 1 hour, mixing in a twin-screw extruder in a zone (1) of 147 degrees C, zone (2) of 187 degrees C, zone (3) of 187 degrees C, zone (4) of 167 degrees C and zone (5) of 177 degrees C, extruding, granulating and drying in vacuum at 35 degrees C for 2 hours.
