Manufacturing method of fluororubber cup

Abstract

The invention relates to a manufacturing method of a fluororubber cup, in particular to a manufacturing method of the fluororubber cup. The manufacturing method of the fluororubber cup includes the following steps that firstly, mixed fluororubber subjected to remilling and thin-passing is sheared into fragments through a shear, the fragments are dissolved in an ethyl acetate solvent, and original fluororubber pulp is prepared; secondly, sand blasting is conducted on a metal framework, and the metal framework is washed through gasoline and acetone and aired; thirdly, coating the metal framework with adhesives, a brush is dipped into the original fluororubber pulp and sprays the original fluororubber pulp on the metal framework coated with the adhesives after solvent in the adhesives are evaporated, and the metal framework is placed at the room temperature so that the ethyl acetate solvent can be evaporated; and fourthly, the metal framework coated with the adhesives and the original fluororubber pulp and a fluororubber material are placed in a mode together to be vulcanized, and the rubber cup is manufactured. The manufacturing method of the fluororubber cup overcomes the defect that the fluororubber cup is prone to the degumming phenomenon, and therefore the percent of pass of the fluororubber cup is increased and reliability of the working quality is improved.

Description

technical field [0001] The invention relates to a method for manufacturing parts, in particular to a method for manufacturing a fluorine rubber cup. Background technique [0002] At present, the manufacturing process of fluorine rubber cups usually adopts: first sandblasting the metal skeleton, then cleaning and drying it with gasoline and acetone, then coating the adhesive, leaving it at room temperature for a certain period of time to fully evaporate the solvent, and then putting the prepared The fluororubber rubber material and the metal skeleton are loaded into the mold for one week, and vulcanized according to the specified vulcanization process. [0003] Using this usual fluororubber cup manufacturing process, the produced cup is prone to degumming between the metal skeleton and the rubber, resulting in poor bonding effect and low pass rate, generally only about 70%. In addition, due to the metal skeleton and rubber The inspection of the bonding effect between fluoror...

Problems solved by technology

[0003] Using this usual fluororubber cup manufacturing process, the produced cup is prone to degumming between the metal skeleton and the rubber, resulting in poor bonding effect and low pass rate, generally only about 70%. In addition, due to the metal skeleton and rubber The inspection of the bonding effect between fluororubbers is a destructive test through the tapping test of rubber cups. Therefore, the inspection and control of the bonding quality of fluororubber cups can only be taken in the form of sampling, which is to a large extent Reduced reliability of working quality of Viton rubber cups
