The invention discloses a
cellulose-reinforcement disc-adhesion-prevention squeaking-prevention abrasion-resistant braking material and a preparation method thereof. The braking material comprises, by weight, the main raw materials of 6-18 parts of natural
cellulose subjected to
flame retarding, thermal stabilization and surface treatment (the surface of the
cellulose is coated with
coupling agents with 1-3% weight), 8-24 parts of modified resin matrixes, 3-12 parts of core-shell rubber
powder, 3-9 parts of epoxidation
vegetable oil, 5-15 parts of friction conditioning agents, 6-12 parts of carbonaceous materials and the balance of
barium sulfate used for filling to 100 parts. The preparation method includes the steps that the natural cellulose is subjected to
flame retarding and stabilization treatment, then the
coupling agents are sprayed to the natural cellulose, the natural cellulose is suspended to be opened, heating is performed at 30-90 DEG C until the
coupling agents are completely soaked, the cellulose subjected to surface treatment and other components are mixed inside a Z-type stirring
machine to obtain mold pressing
powder, the mold pressing
powder is formed at 120-160 DEG C and 5-10 Mpa in a
hot pressing mode,
hot pressing time is determined according to the thickness of a product and is generally 1.5-3 min / mm for fitness. The components with porous structures are added into the ingredients, so that a
brake pad has the disc-adhesion-prevention, squeaking-prevention and abrasion-resistant effects.
