Abstract

The invention provides a production process for a brake pad added with modified nanometer graphene. The production process comprises the following steps: all raw materials are prepared; copper fibers and bamboo charcoal fibers are mixed in molten rosin; the raw materials are mixed to feed in a flour mill for powder milling; a semi-finished brake pad is obtained through mold pressing; the semi-finished brake pad is heated for molding; the molded brake pad is put in a closed container, then, the closed container is vacuumized, the vacuum state is kept by 30 minutes, and nitrogen is put in the closed container for keeping pressure by 10 minutes; the brake pad is heated to reach 60-70 DEG C, and is put in the closed container when the brake pad is hot, and argon is put in the closed container for keeping pressure by 10 minutes; and the brake pad is dipped by 15 minutes in a solution mixed by glacial acetic acid and tartaric acid according to a ratio of 1: 1. The prepared brake pad is higher in wear resistance, is prominently enhancedin heat wear resistance, is high in anti-aging capacity, is excellent in impact resistance, and is lower in thermal expansion and cold shrinkage rate.

Description

technical field [0001] The invention relates to the field of brake pads, in particular to a production process for brake pads with modified nano-graphene added. Background technique [0002] Brake pads are the most critical components in the braking system. The moving parts are locked by the brake pads. The quality of the brake pads determines the braking effect. The brake pads are installed on the steel plate of the brake, and the brake pads are bonded to the steel plate with an adhesive, so that when braking, the brake pads are used to resist the moving parts, causing friction between them and the moving parts, so that the brake pads are installed Vehicles or equipment, etc. slow down, or even lock up. But the performance of the brake pads is closely related to the braking effect. The current brake pads have more or less problems in wear resistance, heat resistance, frost resistance, etc., which will affect the braking effect. Contents of the invention [0003] The te...
