▎ 摘　　要

NOVELTY - Spectrum energy fuel-saving board comprises 65-85 pts. wt. polypropylene, 11-16 pts. wt. nylon 66 resin, 5-8 pts. wt. graphene powder, 10-12 pts. wt. negative ions powder, 1-3 pts. wt. tourmaline powder, 0.2-0.5 pts. wt. antioxidant and 2-3 pts. wt. compatibilizer, the antioxidant is hindered phenolic antioxidant, and the compatibilizer is maleic anhydride grafted . USE - Used as frequency spectrum energy oil-saving plate. ADVANTAGE - The plate atomizes oil molecules, so that they can fully burn and improves combustion efficiency of gasoline , fuel savings of 10-15% gasoline and diesel type vehicles, carbon monoxide and hydrocarbon emission ratios are reduced by 22.7% and 26.5%, respectively, Under the premise of the same mileage, two maintenance is equivalent to three maintenance of the vehicle without the fuel-saving board, which reduces the cost of daily use of the car and has high economic value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing spectrum energy fuel-saving board, comprising (i) taking 65-85 pts. wt. polypropylene and 11-16 pts. wt. nylon 66 resin are ground into 50 meshes in a plastic pulverizer- 100 mesh polystyrene/nylon 66 resin mixed powder, where rotation speed is 5500-7000 revolutions/minutes, and the temperature during grinding is 55-60degreesC, (ii) taking 5-8 pts. wt. graphene powder, 10-12 pts. wt. negative ion powder, grinding with 1-3 pts. wt. tourmaline powder in a plastic mill, where rotation speed is 1000-3000 revolutions/minutes, and temperature during grinding is 45-50 degrees Celsius, and after grinding, 50-70 mesh graphene/negative ion powder/electrical Stone powder mixed powder, introducing polystyrene/nylon 66 resin mixed powder, graphene/negative ion powder/tourmaline powder mixed powder, 0.2-0.5 pts. wt. antioxidant and 2-3 pts. wt. compatibilizer into a plastic mixer and mixing for 30-60 minutes, where rotation speed is 100-200 revolutions/minutes to obtain a mixture, (iii) melting mixture at 260-275degrees Celsius, pouring into the fuel-saving plate mold, cooling to 20-25degrees Celsius, naturally solidifying 1-3 days to get a fuel-saving board.
