▎ 摘  要

NOVELTY - Aqueous anticorrosive paint comprises 27-40 pts. wt. epoxy resin, 2-3 pts. wt. polyester, 1-2 pts. wt. modified graphene, 4-7 pts. wt. solvent, 50-72 pts. wt. deionized water, 1-5 pts. wt. auxiliary agent, 10-20 pts. wt. antirust pigment and 10-20 pts. wt. filler. USE - The anticorrosive paint is useful for steel structure (claimed). ADVANTAGE - The anticorrosive paint far exceeds the requirements of the standard HGH4759-2014 in terms of acid resistance, alkali resistance and salt spray resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the aqueous anticorrosive paint, comprising (i) heating 27-40 pts. wt. epoxy resin and polyester at 100-120 degrees C, and melting completely, (ii) cooling to 80-90 degrees C, then adding modified graphene and stirring for 3-4 hours, (iii) cooling to 50-60 degrees C, then adding solvent and diluting, and continuously stirring for 0.5-1 hour, (iv) adding the melted epoxy resin, stirring uniformly, slowly dropping mixture of 30-42 pts. wt. deionized water and 1-5 pts. wt. auxiliary agent, and (v) increasing the stirring speed, then adding mixture of 10-20 pts. wt. antirust pigment, 10-20 pts. wt. filler and 20-30 pts. wt. deionized water, and continuously stirring for 2-3 hours to obtain final product.
