NOVELTY - Preparing liquid rubber exfoliated graphene and a super hydrophobic composite involves grounding the mineral powder modified nano natural mineral powder and water into the ball milling tank to obtain the suspension, then adding 0.05-5 wt.% powder mass of dispersant and surface modifier, using speed is 500-900 revolutions per minute of the planetary ball mill, ball-milling and dispersing for 30-180 minutes, ultrasonic dispersing for 10-30 minutes. The rotating speed of centrifuge solid-liquid separation is 4000-10000 revolutions per minute for 5-20 minutes, discarding the supernate, respectively by de-ionized water and absolute ethylalcohol to wash, at 40-80 degrees C vacuum drying box for drying the bottom precipitate, obtaining loose dispersed nanometre mineral powder. The ore powder is added to the ball mill tank then water is added to prepare a slurry suspension containing 5-20 g of ore powder per 100 ml of pulp. The dispersant has a mass of 0.05-5% by weight of the ore powder. USE - Method for preparing liquid rubber exfoliated graphene and a super hydrophobic composite. ADVANTAGE - The method enables to prepare liquid rubber exfoliated graphene and a super hydrophobic composite has shorten the process and reduce the cost. DETAILED DESCRIPTION - Preparing liquid rubber exfoliated graphene and a super hydrophobic composite involves grounding the mineral powder modified nano natural mineral powder and water into the ball milling tank to obtain the suspension, then adding 0.05-5 wt.% powder mass of dispersant and surface modifier, using speed is 500-900 revolutions per minute of the planetary ball mill, ball-milling and dispersing for 30-180 minutes, ultrasonic dispersing for 10-30 minutes. The rotating speed of centrifuge solid-liquid separation is 4000-10000 revolutions per minute for 5-20 minutes, discarding the supernate, respectively by de-ionized water and absolute ethylalcohol to wash, at 40-80 degrees C vacuum drying box for drying the bottom precipitate, obtaining loose dispersed nanometre mineral powder. The ore powder is added to the ball mill tank then water is added to prepare a slurry suspension containing 5-20 g of ore powder per 100 ml of pulp. The dispersant has a mass of 0.05-5% by weight of the ore powder. The surface modifier has a mass of 0.05-5% by weight of the ore powder. The liquid rubber stripped graphite to prepare graphene composite latex block, the liquid rubber is put into the mixing tank, and graphite and rubber thinner are added, stirring at a speed of 100-1000 revolutions per minute of the mixer, stirring for 5-10 minutes, forming a uniform liquid rubber-impregnated graphite viscous slurry, and gradually pouring it into the feeding hopper of the peeling machine in operation, cycling and stripping for 30-120 minutes obtaining a uniform liquid rubber peeling graphene mixed emulsion, or graphene oxide mixed latex. The graphite quality is 1-50% of the mass of the rubber, 2-30 ml per 100 g of rubber plus rubber diluent. The liquid rubber stripped graphene mixed emulsion or the graphene oxide mixed emulsion it is added to the reaction kettle together with the functional organic solvent, sealed, heated, stirred, and kept at 120-180 degrees C for 3-16 hours. The rubber stripped graphene mixed emulsion or the graphene oxide mixed emulsion is completely dissolved to obtain a graphene rubber diluent or a graphene oxide rubber diluent, the volume ratio is a mixed latex: functional organic solvent is 1: 10-100. The dilute of graphene rubber is poured into a container, the dispersed nano-mineral powder is added, stirred at 600-1000 revolutions per minute for 5-15 minutes to form a suspension, after ultrasonic dispersion for 5-15 minutes, and the diluted coupling agent solution is added dropwise under constant stirring at 40-80 degrees C. The ammonia water is added dropwise after stirring for 5-15 minutes, and the mixture is further stirred and kept for 5-24 hours to obtain a mineral-graphene-rubber-based superh ydrophobic composite colloid. The each 100 ml of the graphene rubber diluent is added to the dispersed nano-mineral powder 1-5 g, the mass concentration of 15% ammonia water 5-15 ml. The mineral-graphene-rubber-based super hydrophobic composite colloid, an antioxidant, stearic acid, zinc oxide and a promoter are respectively added, after stirring at 100-500 revolutions per minute for 3-10 minutes, an initiator is added and stirred to obtain a super hydrophobic composite cluster dispersion coating solution. The coating liquid is uniformly coated on the surface of the clean glass slide, and the coating amount is 20 mg/cm 2 -50 mg/cm 2, and after completely drying, the coating is applied again. The coating was applied 2-4 times, finally vulcanized in an oven at 100-110 degrees C for 5-15 minutes to prepare a rubber-based nano-mineral-graphene superhydrophobic composite membrane material.
