Embodiment 1
[0037] It is used in the anti-wear coating process of plastic steel parts of electric vehicle chassis, including the following process steps,
[0038] 1) Pretreatment before painting
[0039] Clean the oil and dust on the surface of plastic steel parts, and make the surface of plastic steel parts smooth by sanding and grinding, which is easy for coating;
[0040] 2) Spray primer for the first time
[0041] Preparation of primer: primer consists of 25 parts of xanthan gum, 1 part of red iron oxide, 1 part of graphene, 5 parts of tetrahydrooxane, 3 parts of antioxidant, 3 parts of dispersant, 2 parts of polysiloxane, putty 2 parts of powder, 1 part of emulsifier, 10 parts of polyisoprene, 3 parts of fatty acid, 1 part of octadecanoic acid and 0.5 part of nano-silicon carbide, each component is put into a kneader and kneaded evenly, at 110 Heat mixing at ℃ for 5 hours to make primer;
[0042] Primer spraying: Use spraying equipment to spray the primer on the surface of plastic...
