Embodiment 1
[0031] as attached figure 1 An oil suction pipe assembly product as shown, including a stainless steel joint 1, a fluororubber bellows 2, a support spring 3 and a stainless steel ball head 4, one end of the fluororubber bellows 2 is connected to the stainless steel joint 1, and the other end is connected to the stainless steel ball The head 4 is connected, and the outwardly protruding positions of the pipes of the fluororubber bellows 2 are all provided with support springs 3 . Because of the support spring 3 in this product, the fluorine rubber bellows 2, stainless steel joint 1 and stainless steel ball head 4 cannot be vulcanized and thermally bonded together. After the fluororubber bellows 2, the fluororubber bellows 2, the stainless steel joint 1 and the stainless steel ball head 4 are bonded together by bonding. And the product needs to work under high temperature and lubricating oil conditions.

The invention discloses a fluororubber and metal hot bonding process. The problem that in the prior art, rubber and metal products which cannot be subjected to vulcanization and hot bonding forming are not resistant to high temperature and lubricating oil after being subjected to cold bonding is solved. The process comprises the following steps that one section of fluororubber is subjected to vulcanization forming, and a semi-finished fluororubber product is prepared; the metal surface needing to be bonded and the semi-finished fluororubber product surface needing to be bonded are ground; the ground metal surface and semi-finished fluororubber product surface are cleaned; the cleaned semi-finished fluororubber product surface and metal surface are coated with a layer of first coat adhesive and dried at room temperature; the dried semi-finished fluororubber product surface and metal surface are coated with a layer of mucilage and then dried at room temperature; the dried semi-finished fluororubber product and metal are bonded together through the bonding surfaces; and the bonded semi-finished fluororubber product and metal are placed in a drying box to be heated and vulcanized. The process is simple, convenient to operate, good in bonding effect and resistant to high temperature and lubricating oil.
Description
technical field [0001] The invention belongs to the technical field of rubber and metal bonding, and in particular relates to a fluorine rubber and metal thermal bonding process. Background technique [0002] In the prior art, the bonding process of rubber and metal is mainly divided into two types. One is to smear the adhesive on the metal bonding surface, and then put it into the mold together with the mixed rubber, and vulcanize and bond it through high temperature, high pressure and a certain period of time; Adhesive is applied to the bonding surfaces of rubber products and metals. For some oil suction pipe products with special structure, they cannot be hot-bonded in a mold. If they are bonded by cold bonding, the temperature and lubricating oil resistance of the bonded components often cannot meet the requirements. The adhesive layer dissolves or falls off, and the rubber and metal separate. [0003] Therefore, providing a rubber-to-metal bonding process that does n...
