▎ 摘  要

NOVELTY - Preparing composite material of oxidized graphene/nano barium sulfate involves adding pre-treated graphene waste sulfuric acid, the prefabricated barium carbonate slurry as raw material, the barium carbonate slurry, the waste sulfuric acid respectively to the reaction kettle through the pipeline, in the feeding and mixing process, starting stirring, controlling the pH and temperature of the material in the reaction kettle, reacting for a period of time, aging after reaction, filtering the aged material to obtain product. USE - Method for preparing composite material of oxidized graphene/nano barium sulfate used for preparing downstream product containing graphene and barium sulfate (claimed) and to paint, pigment, coating, ink, storage battery, paper making, plastic, rubber, ceramic, enamel, and spice industries. ADVANTAGE - The method increases the adding amount of barium sulfate in downstream field application, and improves the uniformity of barium sulfate in the downstream system. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing downstream product containing graphene and barium sulfate, involving: preparing graphene oxide/nano barium sulfate composite material, mixing with other components needed by the downstream product to obtain product.
