Abstract

The invention discloses a preparation method of a novel friction material in the technical field of friction materials. The preparation method of the novel friction material is characterized by comprising the following steps: two materials, namely reinforced fibers and calcium carbonate whiskers, are added into a stirrer from two directions at the same time, and stirring is carried out; in the middle of stirring, a catalyst is sprayed through a vacuum spray method for catalytic fusion, and the friction material is prepared, the reinforced fibers and the calcium carbonate whiskers are stirred for 5 minutes, the addition time of the catalyst is within 2.5 minutes after the reinforced fibers and the calcium carbonate whiskers are stirred, the reinforced fibers are composed of Co3<2->, Ca<2+>, Na<+>, Fe<2+>, SiO3<2-> and -(C6H12O6), the reinforced fiber comprises the following components in percentage by weight: 30%-40% of Co< 2->, 20%-30% of Ca<2+>, 5%-10% of Na<+>, 0.5%-1% of Fe<2+>, 10%-15% of SiO<2-> and 10%-20% of -(C6H12O6), and the product can replace asbestos and is more environment-friendly and durable.

Description

technical field [0001] The invention relates to the technical field of friction materials, in particular to a preparation method of a novel friction material. Background technique [0002] Friction material is a component material used in power machinery that relies on friction to perform braking and transmission functions. It mainly includes brake linings (brake pads) and clutch facings (clutch plates). Brake pads are used for braking and clutch plates are used for transmission. Any mechanical equipment and various moving vehicles must have braking or transmission devices. Friction material is a critical component on this braking or transmission. Its main function is to absorb or transmit power through friction. For example, the clutch plate transmits power, and the brake plate absorbs kinetic energy. They enable mechanical equipment and various motor vehicles to work safely and reliably. So the friction material is a widely used and even critical material. [0003] ...
