Problems solved by technology

However, as the drilling depth increases, the power, lifting speed and load of the drilling rig will inevitably increase, so it is necessary to have a suitable braking friction material to cooperate with deep holes, high speed, and heavy load conditions. The dynamic system cannot meet the requirements of this ultra-deep hole drilling operation

Abstract

The invention provides a preparation method of a powder metallurgy friction material for a deep hole drilling machine. The preparation method of the powder metallurgy friction material for the deep hole drilling machine comprises the steps that firstly, silicon carbide is obtained and added into a sodium hydroxide solution to be soaked, heating and heat preservation are conducted, a solid is dried after filtration, the solid is soaked in amine resin, and the solid is cleaned with ethanol water after being taken out of the amine resin and then is dried, so that modified silicon carbide is obtained; secondly, boron nitride, water and propylene glycol are obtained and mixed, so that a mixture is obtained; thirdly, the modified silicon carbide and the mixture are mixed and dried, and prefabricated powder is obtained after ball milling; and finally, the prefabricated powder, cuprous sulfide, tin powder, nickel powder, molybdenum sulfide, tungsten powder, aluminum phosphide, barium sulfate and soya bean lecithin are mixed, the mixture is placed in a metallurgical forming press to be press-formed and then sintered, and then the powder metallurgy friction material for the deep hole drilling machine is obtained. The friction material prepared through the method has good mechanical performance and good friction performance.

Description

technical field [0001] The invention belongs to the technical field of powder metallurgy materials, and in particular relates to a preparation method of powder metallurgy friction materials for deep hole drilling machines. Background technique [0002] In recent years, the consumption of mineral resources has increased year by year. With the consumption of mineral resources and the progress of earth science research, resource exploration and geological research have gradually extended to deep drilling. In order to adapt to resource exploration and geological research, drilling must develop in the direction of deep holes and ultra-deep holes. However, as the drilling depth increases, the power, lifting speed and load of the drilling rig will inevitably increase, so it is necessary to have a suitable braking friction material to cooperate with deep holes, high speed, and heavy load conditions. The dynamic system cannot meet the requirements of this ultra-deep hole drilling op...
