▎ 摘  要

NOVELTY - Color paste comprises 8-12 pts. wt. pigment, 15-20 pts. wt. graphene, 10-15 pts. wt. antirusting agent, 20-25 pts. wt. auxiliary agent, 200-300 pts. wt. solvent and 40-60 pts. wt. cosolvent. USE - The paste is useful in heavy anti-corrosion paint (claimed). ADVANTAGE - The paste: uses graphene, which disperse in the coating and does not undergoes agglomerate; reduces internal defects in the coating; enhances the mechanical properties, physical barrier and corrosion resistance properties of the coating; effectively extends the protection time of the coating to metal; and achieves the purpose of metal corrosion protection. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing color paste comprising (i) taking the above raw materials, (ii) dividing the solvent into two parts, adding pigment and graphene to first solvent, stirring uniformly and grinding to obtain the mixture, and (iii) adding antirusting agent, auxiliary agent and cosolvents to the second solvent, adjusting the pH to 4-5.5, mixing and grinding.
