Abstract

The invention relates to the technical field of ceramic friction materials, particularly a ceramic friction material mixture and a mixing method thereof. Silicon dioxide, molybdenum disulfide, diesel, manganese carbonate ore, phosphorite, graphite, diatomite, ceramic fibers, carbon fibers, a phenolic resin and sodium dodecyl benzene sulfonate used as raw materials are selected and proportioned to prepare the ceramic friction material. The kinetic friction coefficient of the ceramic friction plate prepared from the ceramic friction material is 0.22-0.23, the static friction coefficient is 0.24-0.25, the kinetic/static friction ratio is 0.88-0.955, and the wear rate is 7.5*10<-6>mm<3>.J<-1>-9*10<-6>mm<3>.J<-1>. By combining the raw material proportioning and adding the manganese carbonate ore and phosphorite, the properties of the ceramic friction material mixture are improved, so that the frictional properties (especially stability, oil conductivity and physical and mechanical properties) of the ceramic friction material are improved.

Description

technical field [0001] The invention relates to the technical field of ceramic friction materials, in particular to a ceramic friction material mixture and a mixing method thereof. Background technique [0002] With the characteristics of high hardness, strong wear resistance, strong corrosion resistance and high temperature resistance of ceramic friction materials, ceramic friction materials have developed rapidly in the field of braking. For this reason, a large number of researchers have studied ceramic friction materials. Research has been carried out from multiple angles, such as "A Ceramic Fiber Paper-based Friction Plate and Its Manufacturing Method" with the patent No. 201210374719.2. The purpose is to provide a friction plate with high friction coefficient and good wear resistance; It has the characteristics of simple process and convenient and easy manufacture. The ingredients used are: ceramic fiber, carbon fiber, aramid pulp fiber; long-fiber tissue paper, diato...
