Abstract
The invention discloses a method for preparing a macromolecular composite friction material. The friction material consists of a buffer layer and a friction layer, wherein the buffer layer is made of a rubber matrix macromolecular composite material, and the friction layer is made of a resin-based macromolecular composite material. A track brake friction piece made of the friction material is light and easy to install; in the braking process, when the friction piece is in contact with a wheel, the wheel is not damaged, and the noise is low in the braking process; and in the absence of other substances harmful to the environment such as asbestos in components of the friction piece, the friction piece is environment-friendly and does not have pollution.
