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...

Abstract

The invention discloses a preparation method of a grinding wheel of a tread cleaner, belonging to the technical field of brake material preparation. A preparation method of grinding wheels for tread cleaners of the present invention comprises the steps of granulation, drying, cold pressing, solidification, graphitization of binder and dipping in paint. The purpose of the present invention is to overcome the quality defect that the surface of the existing abrasives is easily oxidized, and to provide a preparation method for the abrasives of the tread cleaner. Maintain stability, and at the same time develop a new type of anti-rust and anti-oxidation coating, which is environmentally friendly and harmless, improves the anti-oxidation function of the grinding wheel, and prolongs the service life of the grinding wheel, thereby reducing production and maintenance costs.

Description

technical field [0001] The invention belongs to the technical field of brake material preparation, and more specifically relates to a preparation method of grinding wheels for tread cleaners. Background technique [0002] Abrasives are a friction part in tread cleaners that have the functions of cleaning, thickening, and rounding. The high-speed development of trains has brought about a large demand for abrasives for high-speed EMUs. Therefore, abrasives play an extremely important role in driving safety. . In the production process, the surface of the grinding wheel will be sprayed with paint before packaging to prevent rust. Painting is harmful to the environment. Therefore, environmental protection treatment equipment must be installed in the painting process to reduce environmental damage. Harm, and environmental protection treatment brings greater treatment costs. Therefore, it is very important to develop an abrasive paint for antirust and antioxidation, which will g...
