Embodiment 1
[0049] A preparation method of the composite friction material of the present invention, the process flow is as follows figure 1 shown, including the following steps:
[0050] (1) Add 410g caprolactam monomer and 8.2g catalyst sodium hydroxide into the first reaction kettle 1 and heat to 130°C, melt, vacuumize (vacuum degree-0.1MPa), and dehydrate for 20min to obtain the first reaction liquid (caprolactam anion ).
[0051] (2) Add 400g of caprolactam monomer into the second reaction kettle 2, melt at 130°C, vacuum dehydrate for 10min, and the vacuum degree is -0.1MPa, mix 72g of polyether glycol (which has been vacuumized for 1 hour) and 18g of di Benzyl methane diisocyanate MDI is added in the second reactor 2, reacts 0.5h, finally adds the colloidal graphite lubricant (the molybdenum disulphide that also has -OH group on the surface for use with -OH group after drying) lubricant, polytetrafluoroethylene lubricant) 45g, and then reacted for 0.5h to obtain the second reactio...
