▎ 摘  要

NOVELTY - Preparation of waterproof non-silicon surface treatment agent involves (s1) acid treating graphene, reacting with thionyl chloride, 4-aminopyridine and p-amino styrene to obtain modified graphene, (s2) reacting polyester polyol and polyisocyanate to obtain prepolymer, adding polyethylene glycol, polyisocyanate and allyl polyol for reacting to obtain modified polyurethane, and (s3) mixing the modified graphene, modified polyurethane, ethyl acetate, ferric chloride, active diluent and chloroplatinic acid. USE - Preparation of waterproof non-silicon surface treatment agent used for self-adhesive silicone rubber and silicone rubber. ADVANTAGE - The waterproof non-silicon surface treatment agent has excellent bonding effect and water resistance.
