<p>For the production of asbestos-free brake linings for railway traffic, having improved coefficients of friction during braking under wet conditions, friction-lining compositions are proposed which contain, as binder, a mixture of nitrile rubber and peroxide-crosslinked polybutadiene liquid resin, and in which a part of the mineral fillers is replaced by alkali metal phosphates, alkaline earth metal phosphates and/or ammonium phosphates.</p> |
