▎ 摘  要

NOVELTY - Preparing automobile paint comprises (a) continuously stirring propylene glycol butyl ether, glycidyl tertiary butyl ester, heating to 130-140 degrees C under the protection of nitrogen to obtain the premix a, (b) adding the nano graphene oxide into ethanol aqueous solution, ultrasonically dispersing for 1-2hours, spraying and drying, adding nano cellulose for grinding for 10-12hours at 1200-1400 revolutions/minute, obtaining the pre-treated nano graphene oxide, (c) mixing the methyl methacrylate, ethyl acrylate, hydroxyethyl acrylate, m-methyl styrene, p-methylstyrene, pre-processing nano graphene oxide uniformly, dropping into the premix a, adjusting the temperature to 140-150 degrees C, adding initiator, acrylic acid and dodecyl mercaptan, stirring uniformly to obtain the premix b and (d) cooling the premix b to 80-88 degrees C, adding neutralizing agent for high speed stirring for 10-15minutes, cooling to 50-60 degrees C and adding water to emulsify to obtain the automobile paint. USE - The method is useful for preparing automobile paint. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an automobile paint prepared by the above method.
