Abstract

The invention discloses a processing method for improving oxidization resistance of a brake caliper sealing part of an electric vehicle. The processing method is characterized by comprising the following steps of: (1) cleaning, using a hydrochloric acid solution to soak, and using deionized water for heating and cleaning; (2) activating, and soaking the sealing part into an activating agent solution to separately activate at a temperature of 52-55 DEG C and a temperature of 63-67 DEG C; (3) performing anti-ageing treatment, and separately soaking the sealing part into a treatment fluid A and atreatment fluid B to perform heating reaction; and (4), curing, wherein the treated part is put into a high-pressure pot cooking layer to subject to curing treatment.

Description

technical field [0001] The invention belongs to the technical field of seal processing, and in particular relates to a processing method for improving the oxidation resistance of electric vehicle brake caliper seals. Background technique [0002] Sealing prevents fluid or solid particles from leaking from adjacent joint surfaces, and prevents external impurities such as dust and moisture from intruding into the internal parts of the machine equipment. It is mainly made of plastic rubber materials. Although it has low cost in the manufacturing process of electric vehicles, it is It plays a very important role in protecting the overall performance of electric vehicles and can prolong the service life of electric vehicles. However, the seal is made of rubber or plastic material. During the sealing process, it is in contact with high-temperature parts of the electric vehicle, and is in contact with the air for a long time. Exposure to high temperature, sunlight, moisture, oxygen...
