[0020] Anti-friction coating The automatic door screw of rail vehicles is composed of a metal substrate and an anti-friction coating, and the surface of the metal substrate is coated with an anti-friction coating, which constitutes the working layer of the screw; anti-friction coating The composition of the layer includes main material composite polymer material, composite solid lubricant, composite solid anti-wear agent and additives.
[0021] The formulation of the anti-friction coating is as follows:
[0022] Solid lubricant: 5% molybdenum disulfide, 12% graphite, 2% graphite fluoride, 6% tungsten disulfide, 2% molybdenum diselenide;
[0023] The wear-resistant agent is: 1% nano-diamond, 3% silicon nitride, 6% aluminum oxide, 3% silicon dioxide, 2% antimony trioxide, 11% silicon carbide, 1% carbon nanotubes;
[0024] Additive: powder surface treatment agent 8%;
[0025] Adhesive: 15% polyester resin, 10% epoxy resin, 13% acrylic resin;
[0026] After mixing, the specifi...
