▎ 摘  要

NOVELTY - An antistatic coating comprises 35-40 pts. wt. water-based polyurethane, 20-30 pts. wt. aqueous acrylic emulsion, 1-2 pts. wt. nano graphene, 3-5 pts. wt. nano zinc oxide, 1-1.5 pts. wt. polytetrahydrofuran polyol, 1-3 parts of carbon nanotubes, 1-2 pts. wt. basalt fiber, 1-3 pts. wt. bis( beta -hydroxyethyl) stearylamine, 1-1.2 pts. wt. N-bromosuccinimide, 1-1.6 pts. wt. 2,4-diphenyl-4-methyl-1-pentene, 1-2 pts. wt. coupling agent, 0.8-1.4 pts. wt. leveling agent, and 2-3 pts. wt. thickener. USE - Antistatic coating for surface of power distribution cabinet. ADVANTAGE - The coating is prepared using several materials which effectively prevent static electricity generated in the power distribution cabinet, reduce dust accumulation, and improve the stability of the use of the power distribution cabinet, and is economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of antistatic coating, which involves adding water-based polyurethane, nano graphene and polytetrahydrofuran polyol in mixer to obtain mixture, stirring the mixture at 1200-1400 rpm for 25-30 minutes, modifying at high temperature of 100-110 degrees C to obtain mixture (A), adding nano zinc oxide, carbon nanotubes and 2,4-diphenyl-4-methyl-1-pentene in deionized water, ultrasonically processing at 220-250 W in frequency of 15-20 kHz, temperature of 60-80 degrees C for 15-20 minutes, homogenizing to obtain homogenized liquid, grinding and pulverizing the basalt fiber through 60-80 mesh sieve, adding the aqueous acrylic emulsion and mixture (A), mixing, treating the mixture in high-pressure autoclave at high temperature of 120-140 degrees C and high pressure of 28-30 MPa for 45-60 minutes to obtain mixture (B), adding the mixture (B) to the homogenized liquid, adding bis( beta -hydroxyethyl) stearylamine, N-bromosuccinimide, coupling agent, and thickener, stirring at 60-70 degrees C, and 120-160 rpm, heating for 40-50 minutes, adding leveling agent to adjust the rotation speed, and mechanically dispersing at 600-800 rpm, room temperature for 25-30 minutes.
