NOVELTY - Chromium drainage agent comprises 110 pts. wt. aluminium oxide, 40 pts. wt. chromium oxide, 20 pts. wt. graphene, 10 pts. wt. bonding agent, 15 pts. wt. silicon carbide, 5 pts. wt. potassium feldspar, 10 pts. wt. quartz sand, 10 pts. wt. carbon additive, and 0.0025 pts. wt. water USE - Chromium drainage agent used in refractory material industry. ADVANTAGE - The chromium drainage agent has fire-resistant, does not produced harmful gas during preparation method, and no peculiar smell, no smoke, completely reaches the specified environmental index and use requirement. The method is simple, and the raw material is rich. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing of fire-resistant chromium drainage agent which involves: (a) preparing the raw materials according to pts.wt.; (b) adding alumina, potassium feldspar into the stirring device, stirring for 1-5 minutes, orderly adding water, bonding agent, carbon additive, stirring for 3-10 minutes until the potassium feldspar is dyed black, adding chromium oxide, bonding agent, silicon carbide, quartz sand, carbon additive, stirring for 5-15 minutes, discharging; and (c) packaging, and waiting for hair.
