Embodiment 1
[0028] A method for preparing a railway locomotive wheel and rail solid lubricating block, comprising the following steps:
[0029] S1: Install the mold and preheat to 90°C;
[0030] S2: Weigh the raw materials according to the following parts by weight: 18 parts of epoxy resin, 30 parts of molybdenum disulfide, 18 parts of halogen-free flame retardant, 5 parts of magnesium oxide, 15 parts of graphite, 7 parts of aluminum oxide, 7 parts of glass fiber, and The above-mentioned raw materials that weigh are placed in internal mixer and mix;
[0031] S3: Fill the mixed raw materials into the preheated mold to ensure that the raw materials fill the mold cavity;
[0032] S4: Carry out conventional molding operation. The molding operation parameters are: temperature 150°C, pressure 8MPa, time 5min. Exhaust gas twice during the molding operation, each exhaust time is 20s, and the exhaust interval time is 1min. The molding operation is completed Finally, keep it under molding tempera...
