NOVELTY - Fluororubber powder is added to polyisocyanate, mechanically mixed, and dry steel fiber, nano-diamond powder, high-purity barium sulfate and erucic acid amide are added and continuously stirred for 1-3 hours, washed and dried. The resultant mixture is then mixed with carbonized graphene-grafted carbon fibers and polytetrafluoroethylene in a high-speed mixer, and cold-forming process is carried out. The resultant material is then sintered-molded to obtain composite material. USE - Manufacture of composite material (claimed). DETAILED DESCRIPTION - Toxic heavy stone leaching solution is purified, and diluted using distilled water, to obtain barium chloride solution. The obtained solution is added to a three-necked flask, and 1-butyl-3-methylimidazolium tetrafluoroborate ionic liquid is added and subjected to microwave extraction synthesis instrument under stirring condition. Preset amount of ammonium carbonate solution is added to a dropping funnel which is connected to the trigeminal interface of the microwave extraction synthesizer. Instrument's microwave power, temperature reflex, reaction time, electromagnetic stirring speed and ammonium carbonate dropping speed are set, and microwave irradiation is carried out. The three-necked flask is then removed, continuously stirred, cooled to room temperature, filtered, and the filter cake is washed using distilled water. The resultant filter cake is then placed in constant temperature drying oven to obtain high purity barium carbonate. The toxic heavy stone is treated at high temperature to produce crude barium oxide. The crude barium oxide is added to a reactor, and the amount of water is heated at 90 degrees C. The crude barium oxide slag is filtered in Buchner bucket and residue is washed using preset amount of hot water. The resultant filtrate is treated with industrial zinc oxide and desulfurization process is carried out. Strontium and calcium impurities are then removed, and the mixture is filtered and washed to obtain clear barium hydroxide liquid. The resultant liquid is then concentrated to produce barium hydroxide concentrate, cooled, crystallized, centrifuged and resultant crystals are then dried to obtain barium hydroxide octahydrate. The obtained high-purity barium carbonate and barium hydroxide octahydrate are mixed to obtain barium salt slurry. Chlorine is then introduced, and the vessel is sealed and stirred to obtain reaction slurry. The sealed reactor is opened, and sulfuric acid is added and the pH is adjusted to 2.5-3. The reaction temperature is then controlled at more than 60 degrees C, and solid-liquid separation is carried out to obtain to obtain pulping solid. The pH of the pulping solid is then adjusted to 8-8.5, washed, and solid-liquid separation is carried out. The solid is then dried to obtain barium sulfate product. Carbon fiber is then added to ethanol solvent, ultrasonically dispersed uniformly, and the pH is adjusted to 4-5 by adding acetic acid. To the resultant mixture, KH550 (RTM: gamma -aminopropyltriethoxysilane) is added, stirred for 8-15 hours, washed using deionized water and vacuum-dried to obtain processed carbon fibers. Graphene oxide is oxidized to peroxydinene oxide by glow discharge plasma technology. Peroxidiene oxide is added to dimethylformamide, stirred, and 4-dimethylaminopyridine, dicyclohexylcarbodiimide and processed carbon fibers are added and reacted at room temperature. The resultant product is then washed using deionized water, and dried in vacuum to obtain carbonized graphene grafted carbon fibers. Fluororubber powder is added to polyisocyanate, mechanically mixed, and dry steel fiber, nano-diamond powder, high-purity barium sulfate and erucic acid amide are added and continuously stirred for 1-3 hours, washed and dried. The resultant mixture is then mixed with carbonized graphene-grafted carbon fibers and polytetrafluoroethylene in a high-speed mixer, and cold-forming process is carried out. The resultant material is then sintered-molded to obtain composite material.
