▎ 摘　　要

NOVELTY - Modified raw lacquer composite paint comprises lignin, aqueous polyurethane, refined raw lacquer, metal-ethanol solution and graphene, where volume ratio between aqueous polyurethane, raw lacquer and ethanol solution is 2-3:4-7:1, and the weight ratio of refined raw lacquer to lignin is 10-15:1. USE - Used as modified raw lacquer composite paint. ADVANTAGE - The paint has improved drying time, adhesion, hardness, and excellent heat resistance and alkali resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing modified raw lacquer composite paint, comprising adding refined raw lacquer into metal-ethanol solution, stirring and reacting for 40-60 minutes, then adding lignin, pressurizing and heating, reacting at 50-70 degrees C for 1-2 hours, then adding aqueous polyurethane, stirring and reacting for 1-3 hours to obtain final product.
