[0049]A kind of preparation method of self-lubricating leaf spring, described preparation method comprises the following steps successively:
[0050] Step 1, prepare self-lubricating coating;
[0051] Step 2, pretreating the surface of the leaf spring body;
[0052] Step 3. Spray the self-lubricating paint on the surface of the leaf spring, and after the self-lubricating paint is cured to form a coating, the self-lubricating leaf spring is obtained.
[0053] In the step 3, the diameter of the spout is 1.3-1.8 μm when spraying, and the distance from the spout to the surface of the leaf spring is 30-40 cm;
[0054] Cure as self-lubricating coating at room temperature for at least 96 hours or at 80°C for 20–30 minutes.
[0055] In said step 1, the preparation method of self-lubricating coating comprises the following steps successively:
[0056] Step 1.1, adding graphene and fluorinated graphite into the mixer according to the mass percentage content, and stirring to obtain a ...
Embodiment 1
[0075] A self-lubricating leaf spring includes a leaf spring body and a coating attached to the surface of the leaf spring body. The coating is formed by curing a self-lubricating paint on the surface of the leaf spring. The thickness of the coating is 40 μm. The content includes the following components: 40% water-based resin, 4.8% dispersant, 1% co-solvent, 35% pigment and filler, 0.05% defoamer, 9% graphite source, wherein the graphene is in The mass percent content in the coating is 6.2%, the particle size of graphene is 16 μm, and the thickness is 10 nm, the mass percent content of the fluorinated graphite in the coating is 2.8%, its fluorocarbon ratio is 1.17, and the particle size is 10.33 μm , thickness is 70nm, and the mass ratio of described graphene and graphite fluoride is 2.2:1;
[0076] The preparation method of described leaf spring is:
