Provided are a friction material composition, friction material, and friction member that have excellent fade resistance and abrasion resistance at high temperatures despite not containing copper which has a high environmental burden or containing 0.5 mass% or less of copper. This friction material composition is configured to be a friction material composition that includes a binding agent, an organic filling material, an inorganic filling material, and a fiber substrate, does not include copper as an element in the friction material composition or contains 0.5 mass% or less of copper, and contains one or more types of inorganic filling material selected from -alumina having an average particle size of 10nm to 50 [mu]m, dolomite having an average particle size of 1-20 [mu]m, calcium carbonate having an average particle size of 1-20 [mu]m, magnesium carbonate having an average particle size of 1-20 [mu]m, manganese dioxide having an average particle size of 1-20 [mu]m, zinc oxide having an average particle size of 10 nm to 1 [mu]m, triiron tetraoxide having an average particle size of 1.0 [mu]m or less, cerium oxide having an average particle size of 0.5-5 [mu]m, and zirconia having an average particle size of 5-50 nm.

The invention relates to a functional material for preparing multifunctional healthy running water and a manufacturing method thereof. Composed of component A and component B, component A is composed of tourmaline, ferric oxide, zinc, copper, magnesium, iron, manganese powder and adhesive auxiliary materials, and is made by low-temperature tableting by special equipment ; Component B is a complex ion element, which is composed of medical stone, wood fish stone, fine wine jade, sepiolite, biotite, volcanic slag, calcium sulfite and clay, and is formed by sintering at high temperature; the preparation of component A : The materials are weighed in proportion, after mixing, heating, cooling, and ball milling to pulverize into micron-sized powders; adding binder to the mixed powder after ball milling and mixing; forming flakes with a punching machine; the prepared black The slices are sent to the heating furnace again to maintain a constant temperature; after cooling, they are packaged for later use. Preparation of component B: Weigh the materials according to the proportion and mix them one by one evenly, add the binder and mix them into agglomerates; inject the agglomerates into the tablet press machine to make sheets, and sinter them in a special sintering furnace after drying. Get the desired product. The water quality after being treated by the multi-functional healthy living water material prepared by the present invention has no toxic and harmful substances to the human body, and has no peculiar smell and good taste; the water body has moderate hardness and contains minerals and trace elements needed by the human body; the water body is weakly alkaline Nature, small molecular group water, the oxidation-reduction potential of water is reduced to a negative value at -200 ~ -550MV, and the nutritional and physiological functions of the water body are strong.
