Embodiment 1
[0041] combine figure 1 and figure 2 , a kind of preparation method of tread sweeper grinder of the present embodiment, comprises the following steps:
[0042] Step 1, granulation, put the binder, graphite, carbon fiber, copper fiber, boron carbide and iron powder into the mixer in sequence according to the formula ratio for pre-homogenization and fiber opening. The pre-homogenization time is 580s, and then add The organic solvent is used for granulation, and the granulation time is 120s to obtain the mixture A;
[0043] Step 2, drying the material, putting the mixture A into an oven for drying treatment, the drying time is 2.5 hours, and obtaining the qualified material B, and the qualified material B is a mixture with a volatile content of less than 1%;
[0044] Step 3, cold pressing, put the qualified material B into the cold pressing mold for cyclic pressing, the specific process parameters are as follows: the product surface pressure is 50MPa for 30s, 30MPa for 60s, 50...
Embodiment 2
[0063] A kind of preparation method of tread cleaner grinder of the present embodiment, its steps are basically the same as embodiment 1, the difference is:
[0064] Step 1, granulation, put the binder, graphite, carbon fiber, copper fiber, boron carbide and iron powder into the mixer in turn according to the formula ratio for pre-homogenization and fiber opening. The pre-homogenization time is 600s, and then add The organic solvent is used for granulation, and the granulation time is 120s to obtain the mixture A;
[0065] Step 2, drying the material, putting the mixture A into an oven for drying treatment, the drying time is 3 hours, and obtaining the qualified material B, and the qualified material B is a mixture with a volatile content of less than 1%;
[0066] Step 3, cold pressing, put the qualified material B into the cold pressing mold and press it circularly. The specific process parameters are as follows: the product surface pressure is 20MPa for 30s, 40MPa for 60s, 5...
Embodiment 3
[0079] A kind of preparation method of tread cleaner grinder of the present embodiment, its steps are basically the same as embodiment 1, the difference is:
[0080] Step 1, granulation, put the binder, graphite, carbon fiber, copper fiber, boron carbide and iron powder into the mixer in turn according to the formula ratio for pre-homogenization and fiber opening. The pre-homogenization time is 620s, and then add The organic solvent is used for granulation, and the granulation time is 110s to obtain the mixture A;
[0081] Step 2, drying the material, putting the mixture A into an oven for drying treatment, the drying time is 2.8h, and obtaining the qualified material B, and the qualified material B is a mixture with a volatile content of less than 1%;
[0082] Step 3, cold pressing, put the qualified material B into the cold pressing mold for cyclic pressing, the specific process parameters are as follows: the product surface pressure is 11MPa for 30s, 27MPa for 60s, 50MPa fo...
