NOVELTY - Rubber composite material for bicycle tires comprises 45-80 pts. wt. butylbenzene rubber, 50-70 pts. wt. natural rubber, 5-13 pts. wt. calcium sulfate crystal whiskers, 4-10 pts. wt. carbon fiber, 2-5 pts. wt. yttrium, 3-8 pts. wt. graphene, 1-3 pts. wt. potassium persulfate, 3-7 pts. wt. dimethyl silicone oil, 6-12 pts. wt. octyl epoxy stearate, 1-5 pts. wt. antimony trioxide, 2-6 pts. wt. sulfur powder, 5-10 pts. wt. clay, 2-5 pts. wt. anti-aging agent, 1-5 pts. wt. flexibilizer, 5-10 pts. wt. aluminum nitride, 3-8 pts. wt. nano boron nitride, 5-13 pts. wt. trioctyl trimellitate, 2-6 pts. wt. paraffin oil. USE - Rubber composite material for bicycle tires. ADVANTAGE - The rubber composite material for a bicycle tire casing has good wear resistance and corrosion resistance, which improves performance and prolongs service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing a rubber composite material for a bicycle tire involves weighing each raw material component, adding calcium sulfate crystal whiskers, cerium oxide, graphene, octyl epoxy stearate, aluminum nitride, nano boron nitride and clay to the stirrer, stirring at 73-76 revolutions per minute (rpm) to obtain preliminary materials, mixing butylbenzene rubber and natural rubber into an internal mixer, mixing at a temperature of 83-88 degrees C, where the internal speed of the mixer is 58-65 rpm, and the temperature of the material is raised to 90-92 degrees C, adding the auxiliary materials potassium persulfate, dimethicone, antimony trioxide, anti-aging agent, flexibilizer, trioctyl trimellitate and paraffin oil for 12-15 minutes, continuing to add carbon fiber to mix uniformly, discharging the temperature upto 138-142 degrees C, releasing, adding sulfur powder for 9-12 minutes, where the reaction temperature is 150-160 degrees C, and discharging the rubber composite material for the bicycle tire.
