Problems solved by technology

Engine mounts and chassis bushings are common automobile shock absorbers. This type of shock absorber is generally a combination of metal and rubber. The strength requirements are extremely high. If the bonding strength cannot meet the requirements, the rubber and metal skeleton in the shock absorber will be debonded during the driving process of the car. If the degree of degumming is light, the friction between the metal and rubber at the degummed part will Abnormal noises will affect driving comfort; and when the degumming area is large and the degree of degumming is serious, it will lead to failure of parts and directly affect driving safety
[0003] At present, the rubber used to connect the metal skeleton in the metal rubber shock absorber is generally composed of raw rubber, protection system, filling system, softening system and vulcanization system. The rubber composed of the above components cannot meet the requirements of metals such as engine mounts and chassis bushings. The requirements for the bonding strength of rubber shock absorbers can easily lead to degumming of parts, which will affect the comfort and safety of driving

Abstract

The invention discloses a rubber and metal framework bonding method, which is characterized by comprising six steps including preparation of rubber, cleaning of a metal framework, drying of the metalframework, covering of primer, covering of surface glue and vulcanization. Through the above method, bonding strength between rubber and the metal framework can be remarkably enhanced, and it is ensured that rubber has good processability.

Description

technical field [0001] The invention relates to a bonding method, in particular to a bonding method of rubber and metal skeleton. Background technique [0002] With the rapid development of the automobile industry, the requirements for automobile safety, comfort and driving operability are getting higher and higher, and the demand for automobile shock absorbers is also higher and higher. Engine mounts and chassis bushings are common automobile shock absorbers. This type of shock absorber is generally a combination of metal and rubber. The strength requirements are extremely high. If the bonding strength cannot meet the requirements, the rubber and metal skeleton in the shock absorber will be debonded during the driving process of the car. If the degree of degumming is light, the friction between the metal and rubber at the degummed part will Abnormal noises will affect driving comfort; and when the degumming area is large and the degree of degumming is serious, it will lead...
