▎ 摘  要

NOVELTY - Paint comprises 30-50 pts. wt. film-forming resin, 5-30 pts. wt. resin additive, 0.1-2 wt.% graphene, 10-20 pts. wt. pigment, 0-10 pts. wt. filler, 2-5 pts. wt. additive, 10-40 pts. wt. solvent and 0.5-1 pt. wt. thixotropic agent. USE - The paint is useful for heat exchanger. ADVANTAGE - The paint has excellent corrosion resistance, wide application range, convenient construction and high temperature resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of preparing the paint, comprising (i) preparing the above-mentioned components, (ii) adding 10-40 wt.% solvent to reaction kettle, heating at 60 degrees C, and stirring, (iii) keeping stirring, adding resin additive to reaction kettle, stirring for 0.5-2.5 hours, and taking out, (iv) adding residual solvent to reaction kettle, adding bentonite while stirring, and completely dispersing particles and blocks, (v) adding residual components to reaction kettle, and stirring until the materials are uniformly mixed, (vi) grinding the material uniformly mixed in step (v) to less than 30 mu , (vii) adding resin additive obtained in step (iii), slowly stirring for 0.5-2.5 hours, adjusting viscosity, and cooling to room temperature.
