Abstract
The invention relates to a method for producing a friction lining of a brake shoe, wherein a binder is added to an open-pore carrier material having a high specific surface area, and the carrier material and the binder are mixed until the carrier material is almost completely wetted with the binder, wherein a functional material is then added that is at least partially absorbed by the carrier material. The invention also relates to a corresponding brake lining.
Claims22
A method for producing a friction lining of a brake shoe, comprising:
- adding a binder to an open-pore carrier material that has a high specific surface area,
- mixing the carrier material and the binder until the carrier material is largely wetted with the binder to form a mixture, and
- subsequently adding to the carrier material-binder mixture one or more functional materials that is at least partially absorbed by the carrier material.
A friction material for a brake shoe of a motor vehicle, comprising:
- a carrier material with a high open porosity selected from the group consisting of:
- diatomaceous earth, clay, a mixture of diatomaceous earth and clay, and a mixture of calcinated diatomaceous earth and clay, which is wetted with a binder, and into or onto which one or more functional materials, is applied or incorporated.

A method for making a friction lining for a brake shoe, comprising:
- mixing an open-pore carrier material having particle sizes between 90 μm and 1.5 mm selected from the group consisting of:
- diatomaceous earth, clay, a mixture of diatomaceous earth and clay, and a mixture of calcinated diatomaceous earth and clay, with a binder solution to form a mixture;
- adding to the carrier material-binder mixture one or more functional materials selected from the group consisting of:
- a metal sulfide, graphite, and mixtures thereof, to form a mixture;
- drying the mixture of carrier material, binder and functional material(s) until the residual moisture of the mixture is between 0.3% and 5%;
- and
- forming the mixture into a friction lining for a brake shoe.
