▎ 摘  要

NOVELTY - Anti-fouling and wear-resistant conductive paint comprises 30-35 pts. wt. polyurethane acrylate, 15-25 pts. wt. epoxy acrylate, 10-15 pts. wt. hexanediol diacrylate, 8-10 pts. wt. self-made anti-wear conductive filler, 2-3 pts. wt. 2-isopropyl thioxanthone, 0.5-0.6 pts. wt. polydimethylsiloxane. The self-made anti-wear conductive filler is prepared by the reaction of modified expanded graphite, deionized water, and sodium hypophosphite. The modified expanded graphite is prepared by the mixed reaction of pretreated expanded graphite and sodium tetrachlorocopperate solution. The pretreated expanded graphite is prepared by the mixed reaction of expanded graphite powder, deionized water and cetyltrimethylammonium bromide. USE - Used as anti-fouling and wear-resistant conductive paint. ADVANTAGE - The paint has anti-wear, anti-static and anti-fouling, and makes up for the traditional defects of anti-static coatings with poor anti-wear and anti-fouling properties have broad application prospects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the anti-fouling and wear-resistant conductive paint, comprising (i) taking all the above mentioned raw materials, and (ii) adding polydimethylsiloxane and 2-isopropyl thioxanthone into the reactor together, and dispersing at a high speed of 500-600 revolutions/minute (rpm) for 5-10 minutes, and then adding homemade anti-oxidant to the reactor, grinding the conductive filler, continue to dispersing at a high speed of 500-600 rpm for 5-10 minutes, raising the temperature to 50-60 degrees C, continue to adding polyurethane acrylate, epoxy acrylate, hexanediol diacrylate, and nano-titanium dioxide functional suspension liquid, stirring evenly at a speed of 200-300 rpm.
