Terahertz material for emission reduction and fuel saving of gasoline vehicle and preparation method therefor and application thereof

A preparation method for a terahertz material, comprising the following steps:

• (1) mixing crude silicon, SiO2 and Binchotan in a weight ratio of 1:(3-5):(5-10), and heating to 700-1500° C. in an oxygen-free environment for 1-8 hours to obtain a silicon-containing oxide black crystal;
• (2) mixing the prepared silicon-containing oxide black crystal with other raw materials in parts by weight:
• 35 silicon-containing oxide black crystal, 3 Al2O3, 45 SiO2, 5 Fe2O3, 40 ochre, 0.5 barium tungstate, 25 CaCO3, wherein the silicon-containing oxide black crystal is made by mixing crude silicon, SiO2 and Binchotan in a weight ratio of 1:5:10, and heating to 1500° C. in an oxygen-free environment for 1 hour;
• crushing to obtain a mixture, wherein the fineness of the mixture reaches 200-500 mesh, and then adding an appropriate amount of water, stirring and turning into small balls, heating to 600-1200° C. in an oxygen free environment for 3-8 hours, and carrying out a secondary crushing;
• (3) detecting a raw terahertz material, if the raw terahertz material has an infrared emissivity which is ≥0.92, and then crushing and powdering the raw terahertz material to make the fineness of the crushed and powdered raw terahertz material more than 10000 mesh, and then enhancing the crushed and powdered raw terahertz material by a terahertz irradiation line to obtain a terahertz material for emission reduction and fuel saving of gasoline vehicle.
