Mine hoist hard magnetic brake shoe material formula and producing thereof

The invention discloses a mine hoist hard magnetic brake shoe material formula and a producing method thereof, the mine hoist hard magnetic brake shoe material comprises the following components in parts by weight: 10 to 20 parts of an organic binder, 15 to 50 parts of a reinforcing fiber, 15 to 45 parts of a friction performance regulator, 3 to 10 parts of a filler and 5 to 40 parts of a hard magnetic material. The producing method comprises crushing, mixing, hot pressing forming, magnetizing, heat treatment and surface processing technology and the like. The beneficial effects are that: a mine hoist hard magnetic brake shoe shows stable friction and wear properties and good heat resistance, and is better adapted to high speed and heavy load extreme braking working conditions; the added hard magnetic material increases the friction coefficient and reduces wear rate of the mine hoist brake shoe, the magnetized brake shoe has higher remanent magnetization and provides most basic material conditions for the magnetic field control of the braking friction process. The magnetized mine hoist hard magnetic brake shoe can maintain magnetism for a long term, the friction behavior can be influenced and adjusted in the braking process without an applied magnetic field.
