▎ 摘  要

NOVELTY - Manufacture of paint binder involves dissolving waste styrene resin in aromatic solvent, preparing solution (s1) by mixing 8.6 plus minus 3% fatty acid, 7.8 plus minus 3% pentaerythirol and 4.1 plus minus 3% phthalic anhydride until acid group reached 10-13, and preparing solution (s2) by mixing 18.6 plus minus 3% xylene with solution (s1), preparing solution (s3) by reacting 28.6 plus minus 3% styrene monomer, 0.4 plus minus 3% ditetrabutyl pentoxide and 0.3 plus minus 3% benzoyl peroxide with solution (s2), diluting the solution (s3) in 20.6 plus minus 3% xylene to prepare a admixture polymer, and mixing 40% waste styrene resin dissolved in the aromatic solvent and 0.03% graphene in admixture polymer. USE - Manufacture of paint binder. ADVANTAGE - The method is environmentally-friendly, and enables manufacture of paint binder having excellent adhesiveness.
