▎ 摘  要

NOVELTY - Preparing gold pigment masterbatch involves formulating 0.5-5 pts. wt. coupling agent into coupling agent alcohol solution with alcohol, dispersing 0.5-3 pts. wt. graphene in first solvent to prepare graphene suspension, adding 85-95 pts. wt. sheet copper. The powder and obtained graphene suspension and coupling agent alcohol solution are heated and stirred in high-speed mixer, and dried to obtain graphene-coated flake copper powder. The graphene-coated flake copper powder is melt-blended with appropriate amount of PLA, and obtained blend is extracted with second solvent and dried to prepare gold pigment masterbatch. USE - Method for preparing gold pigment masterbatch in composite material (claimed). ADVANTAGE - The method enables to prepare gold pigment masterbatch that has low VOC, coating-free, scratch resistance, aging resistance, good mechanical property, and reduces injection molding mark and weld.
