▎ 摘　　要

NOVELTY - A graphene oxide salt-based polyvinyl chloride (PVC) composite stabilizer contains 10-50 pts. wt. auxiliary stabilizer, and 50-90 pts. wt. main stabilizer containing graphene oxide salt and composite metal soap. USE - Graphene oxide salt-based polyvinyl chloride composite stabilizer (claimed). ADVANTAGE - The stabilizer compound has good thermal, static, and dynamic stability effects, high toughening effect, is nontoxic, improves PVC tensile strength, and method is simple, low cost, environment-friendly, and uses raw materials which are readily available. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene oxide salt-based PVC composite stabilizer which involves mixing graphene oxide and inorganic alkali, reacting to obtain oxidized graphite alkene salt, removing inorganic alkali by centrifugation, and/or semi-permeable osmotic method, drying to obtain graphene oxide salt and composite metal soap, adding water, uniformly mixing to obtain main stabilizer, adding auxiliary stabilizer, and uniformly mixing. DESCRIPTION OF DRAWING(S) - The drawing shows an illustration of the blocking effect of graphene oxide salt on hydrochloric acid gas.
