Abstract

The invention discloses a production process of a ceramic friction plate. The production process comprises the following steps that mineral fibers, aramid fibers and ceramic fibers are mixed inside amixer, and then boron nitride, graphite, brass powder and silicone rubber powder are sequentially added into the mixer for full stirring so as to obtain a mixture A; after the mixture A is heated inside the mixer, the mixer is opened, and then a liquid rubber agent is added into the mixer, so that the mixture A and the liquid rubber agent are stirred for 10 mins in an open state of the mixer to bemixed into a mixture B; and then mixed gas generated by mixing the liquid rubber agent and the mixture A at a high temperature is discharged, the mixture B which is in a liquid state is directly discharged to forming equipment through the mixer, the mixture B in the liquid state is extruded into the friction plate, and standing, cooling and form-stabilizing are carried out on the formed frictionplate by using the forming equipment of cooling equipment. And therefore, the obtained friction plate is high in toughness and good in heat conduction performance, the wear resistance of the frictionplate is effectively improved, and the service life of the friction plate is effectively prolonged.

Description

technical field [0001] The invention relates to the production field of ceramic friction plates, in particular to a production process of ceramic friction plates. Background technique [0002] Friction material is a component material used in power machinery that relies on friction to perform braking and transmit kinetic energy. Any mechanical equipment and various moving vehicles must have braking or transmission devices. Friction material is a critical component on this braking or transmission. Its main function is to absorb or transmit power through friction. For example, the clutch plate transmits power, and the brake plate absorbs kinetic energy. They enable mechanical equipment and various motor vehicles to work safely and reliably. So the friction material is a widely used and crucial material. [0003] Especially in recent years, with the rapid development of the automobile industry, people have higher and higher requirements for braking performance, and ceramic...
