NOVELTY - A cold-resistant rubber material comprises 140B-type chlorinated polyethylene, ethylene-propylene-diene rubber, styrene-butadiene rubber, modified graphene, silica, nano calcium carbonate, ultrafine talc, calcined clay, sulfur powder, accelerator AA, accelerator MZ (zinc 2-mercaptobenzothiazole), magnesia, A-172 (RTM: vinyltriethoxysilane), antioxidant MB (2-mercaptobenzimidazole), antioxidant RD (2,2,4-trimethyl-1,2-dihydroquinoline), dioctyl ester, stearic acid and dioctyl terephthalate. USE - Cold-resistant rubber material (claimed). ADVANTAGE - The rubber material has excellent cold resistance and anti-impact property. DETAILED DESCRIPTION - A cold-resistant rubber material comprises 60-80 pts. wt. 140B-type chlorinated polyethylene, 20-30 pts. wt. ethylene-propylene-diene rubber, 25-30 pts. wt. styrene-butadiene rubber, 28-32 pts. wt. modified graphene, 16-20 pts. wt. silica, 6-10 pts. wt. nano calcium carbonate, 12-16 pts. wt. ultrafine talc, 8-12 pts. wt. calcined clay, 0.8-1.2 pt. wt. sulfur powder, 2.8-3.1 pts. wt. accelerator AA, 2-2.3 pts. wt. accelerator MZ, 4-5 pts. wt. magnesia, 2.4-2.8 pts. wt. A-172 (RTM: vinyltriethoxysilane), 0.8-1.2 pt. wt. antioxidant MB, 0.8-1.2 pt. wt. antioxidant RD, 4-6 pts. wt. dioctyl ester, 5-7 pts. wt. stearic acid and 3.6-4.4 pts. wt. dioctyl terephthalate. The modified graphene is obtained by adding 95-98 wt.% concentrated sulfuric acid in a reactor at 0-3 degrees C, stirring, adding 10-13 pts. wt. graphite powder and 5-9 pts. wt. sodium nitrate, stirring at 15-20 rpm for 30-35 minutes, adding 30-33 pts. wt. potassium permanganate, heating at 33-36 degrees C for 28-32 minutes, adding 500-520 pts. wt. deionized water, reacting at 94-98 degrees C for 16-20 minutes, adding 26-31 wt.% hydrogen peroxide and 36.5-38 wt,% hydrochloric acid, dripping graphene oxide solution, centrifuging, adding 170-190 pts. wt. sodium deoxycholate, stirring at 80-120 rpm for 36-44 minutes, further adding 72-78 wt.% hydrazine hydrate solution, reacting at 78-82 degrees C for 12-16 hours, and filtering. The graphene oxide solution is obtained by dissolving 1.8-2.1 pts. wt. graphene oxide in 820-900 pts. wt. deionized water, ultrasonically dispersing at for 1-1.5 hours. An INDEPENDENT CLAIM is included for preparation of cold-resistant rubber material, which involves adding 140B-type chlorinated polyethylene, ethylene-propylene-diene rubber and styrene-butadiene rubber in mixer, mixing, adding modified graphene, silica, calcium carbonate, ultrafine talc, calcined clay and A-172 (RTM: vinyl tri(2-methoxy ethoxy)silane), stirring, adding magnesia, dioctyl ester, stearic acid, and dioctyl phthalate, kneading, adding antioxidant MB, antioxidant RD, sulfur, accelerator AA and accelerator MZ, reacting, and cooling.
