NOVELTY - Preparing a special unsaturated resin involves mixing and dispersing 10-20 pts. wt. graphene oxide, 8-10 pts. wt. surfactant and 200-300 pts. wt. water ultrasonically, and then ball-milling, filtering, washing and drying it to obtain pre-oxidized graphene. The carbon fiber and silane coupling agent ethanolic solution are heated and refluxed at a mass ratio of 1:8-1:10, then filtered, washed and dried to obtain modified carbon fiber. The method involves heating and stirring 10-15 pts. wt. nano-calcium carbonate, 60-80 pts. wt. linoleic acid, and 20-30 pts. wt. carbomer under argon protection. USE - Method for preparing a special unsaturated resin for automobile putty ash. ADVANTAGE - The method enables to prepare a special unsaturated resin, which significantly improves automobile ash mechanical property, flexibility and impact resistance. DETAILED DESCRIPTION - Preparing a special unsaturated resin involves mixing and dispersing 10-20 pts. wt. graphene oxide, 8-10 pts. wt. surfactant and 200-300 pts. wt. water ultrasonically, and then ball-milling, filtering, washing and drying it to obtain pre-oxidized graphene. The carbon fiber and silane coupling agent ethanolic solution are heated and refluxed at a mass ratio of 1:8-1:10, then filtered, washed and dried to obtain modified carbon fiber. The method involves heating and stirring 10-15 pts. wt. nano-calcium carbonate, 60-80 pts. wt. linoleic acid, and 20-30 pts. wt. carbomer under argon protection, adjusting pH to neutral, and then subjecting it to vacuum dehydration to obtain nano-calcium carbonate dispersion. The method involves heating 8-10 pts. wt. phthalic anhydride, 10-15 pts. wt. diethylene glycol, 8-10 pts. wt. ethylene glycol, 4-6 pts. wt. propylene glycol, 3-5 pts. wt. cottonseed oil, 4-6 pts. wt. fumaric acid, 10-15 pts. wt. maleic anhydride, 40-50 pts. wt. styrene, 10-15 pts. wt. pre-oxidized graphene oxide, 8-10 pts. wt. modified carbon fiber, and 6-8 pts. wt. nano calcium carbonate dispersion under reflux condition for 4-6 hours to obtain heated material, which is added with fumaric acid and maleic anhydride, reacted for 3-5 hours under reflux condition, temperature is lowered, vacuum is applied, styrene is added, stirred, mixed and cooled naturally, and then discharged to obtain final product.
