Abstract
The invention relates to a method for preparing the brake sheet of a sedan from rubber-coated steel fibers in the field of friction materials, and provides a method for preparing a brake sheet with obviously improved noiseless or low-noise performance. The brake sheet comprises the following components: the rubber-coated steel fibers, resin, fibers, a friction increasing agent, a friction reducing agent, a friction adjusting agent and a filler, and is prepared by the following process of preparing materials, mixing the materials, performing cold forming, vulcanizing, grinding and checking, wherein the friction reducing agent is graphite; the friction adjusting agent is friction powder; the material comprises the rubber-coated steel fibers and the resin, and the fibers are aramid short fibers; the fiction increasing agent is prepared by mixing corundum and iron oxide red; and the filler is prepared by mixing barium sulfate and heavy calcium carbonate vermiculite powder. The brake sheet prepared by the technical method of the invention is subjected to American LINK3900 rack detection, all properties of the brake sheet meet requirements, and the noise detection is qualified. In addition, the technology does not need to improve the conventional process, so that production and improvement cost is greatly saved.
