Embodiment 1
[0041] (1) As described in Comparative Example 1.
[0042] (2) Mix the components in the self-lubricating composite material uniformly, and dry them at a temperature of 100-130° C. for 2-3 hours until drying for later use; the self-lubricating composite material includes the following mass percentages of each component: 20% polymer Imide (PI) and 80% nano-MoS 2 ;
[0043] (3) after pre-treating the surface of the mold, the self-lubricating composite material described in step (2) is pre-filled into the micro-dimples on the surface of the friction pair described in step (1) with a mold hot pressing curing filling method; The self-lubricating composite material is pressurized by the press to carry out pressure-holding, hot-pressing, curing and filling; the mold hot-pressing curing and filling part is the same as that described in Comparative Example 1, and then the upper and lower sets of nuts of the simple mold pressing device that have been tightened are sleeved respectively. ...
Embodiment 2
[0051] (1) As described in Comparative Example 1.
[0052] (2) Mix the components in the self-lubricating composite material uniformly, and dry them at a temperature of 100-130° C. for 2-3 hours until they are dry for later use; the self-lubricating composite material includes the following mass percentages of each component: 10-15 % Polyimide (PI), 74-80% Nano MoS 2 , 0-12% carbon nanotube additives (CNTs), 0-5% binder;
[0053] (3) after pre-treating the surface of the mold, the self-lubricating composite material described in step (2) is pre-filled into the micro-dimples on the surface of the friction pair described in step (1) with a mold hot pressing curing filling method; The self-lubricating composite material is pressurized by a press to perform pressure-holding, hot-pressing, curing and filling; this step (3) is the same as that in Example 2.
[0054] (4) The friction pair filled in step (3) was first heated at a temperature of 250° C. for 20 min, and then heated in...
