▎ 摘　　要

NOVELTY - A bacteriostatic biological antifouling agent comprises 100 pts. wt. fiber separation and extrusion waste liquid, 0.1-10 pts. wt. natural rubber, 0.01-0.1 pt. wt. graphene oxide, 0.01-0.5 pt. wt. graphene, 0.1-5 pts. wt. initiator and 1-20 pts. wt. acrylic acid. USE - Bacteriostatic biological antifouling agent is used for preventing fouling of water flow pipe. ADVANTAGE - The bacteriostatic biological antifouling agent can inhibit the reproduction of microorganisms in water. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the bacteriostatic biological antifouling agent, which involves taking fiber separation and extrusion waste liquid, removing small amount of solid impurities by centrifugation, neutralizing with hydrochloric acid to adjust pH to neutral, adding natural rubber, graphene oxide and graphene, uniformly stirring, slowly adding initiator and acrylic acid, reacting at 50-100℃ for 1-5 hours, and vacuum-drying at 50℃ to obtain a dry solid which is the bacteriostatic biological antifouling agent.
