Problems solved by technology

The position of the car brake gasket in the car brake system is to be attached to the back of the brake pad steel plate. At present, most of the brake gaskets and cylinder gaskets in automobile manufacturing are made of ordinary steel plates. Ordinary steel plates have low friction resistance and no A cladding material of a certain thickness is prone to rust and brittleness after being used for a certain period of time, and will deform after long-term wear, and a pure steel plate will break when it is shaken strongly
Ordinary steel plate brake pads will not only produce a lot of noise but also cause the body to vibrate during the braking process of the car

Abstract

The invention relates to an alloy glue-coated steel plate used for an automobile braking system and a sealing gasket, and a preparation method thereof. The alloy glue-coated steel plate employs a surface-deoxidized alloy steel plate as a substrate; and a single surface or double surfaces of the alloy steel plate are coated with a gelatinize layer. The main raw materials of the gelatinize layer are rubber latex and sulphur, carbon black, light calcium, etc. The alloy glue-coated steel plate can slow down impact, has rebound capacity, does not carbide and appear cracks at the temperature of 250 DEG C, and keeps the smoothness of a national first-level surface coating. Effects of sealing, damping and reducing braking noises can be achieved by coating a 10 [mu]m gelatinize layer on the double surfaces of the alloy glue-coated steel plate respectively.

Description

technical field [0001] The invention relates to an alloy steel plate for an automobile brake system and a gasket, in particular to an alloy glue-coated steel sheet for an automobile brake system and a gasket and a preparation method thereof. Background technique [0002] A gasket is a part or combination of parts clamped between two separate joints, whose function is to keep the two joints sealed and shock-resistant and sound-absorbing for a predetermined service life. The gasket must be able to seal the joint surface, be impermeable to the sealing medium and not be corroded, and be able to withstand the effects of temperature and pressure. When the compression force on the gasket changes, in order to ensure the sealing, in addition to giving full consideration to the structural design, the compensation ability of the gasket itself is very important. Relying on the springback compensation of the gasket coating is the most economical and effective way, so the resilience of t...
