The pretreatment has two modes, one mode is shot blasting treatment on the framework 1, the current of the shot blasting treatment is 10-15A, the time is 5-10 min, and the roughness Rz is 20-60; the other method is to sequentially carry out degreasing treatment, water washing treatment and drying treatment on the framework 1, wherein the degreasing treatment temperature is 50-60 ℃, the time is 5-15 min, and the free alkalinity is 10-15; the function of the device is that impurities on the framework 1 can be effectively removed after pretreatment, and after bonding and vulcanization, no bubbles exist between the framework 1 and the rubber part 2, so that the service life of the automobile vibration damper is effectively ensured.
When the existing framework is bonded with a rubber part, manual gluing is carried out on the framework, gluing is only carried out on the bonding position of the framework and the rubber part, missing coating is easy to occur due to the fact that the framework 1 is provided with a plurality of concave-convex parts, and the missing coating position is difficult to find due to the fact that glue is transparent, the framework 1 in the step (2) is completely immersed in a glue pool, and the problem that glue is missing coated on the bonding position of the framework 1 and the rubber part 2 can be effectively avoided.
During gum dipping, the first annular body 11 in the framework 1 is firstly immersed into a glue pool, the second annular body 12 is then immersed into the glue pool, then the framework 1 is taken out from the glue pool, and the glue on the framework 1 is dripped into the glue pool under the action of the self gravity.

In the embodiment, the glue in the glue pool comprises a silica gel glue matrix and a modified heat conducting agent, the weight ratio of the modified heat conducting agent to the silica gel glue matrix is 3 per thousand-1%, the modified heat conducting agent is a compound of silanized aluminum oxide and silanized molybdenum powder, and the weight ratio of the molybdenum powder to the aluminum oxide is 0.9-1. Firstly, mixing the silica gel glue machine body with the modified heat conducting agent, then diluting by 5 times, injecting into a glue pool, arranging a stirring device in the glue pool, and continuously stirring.
Through a large number of experiments, under the same conditions, the weight ratio of the modified heat conducting agent to the silica gel glue matrix is only changed, and then the separation force between the vulcanized adhesive and the framework is detected, so that the following table 1 is obtained:
table 1: test data of separation force between skeleton and different heat-conducting agents
