Problems solved by technology
Therefore, after dissection of the vulcanized watertight connector rubber body in the ordinary atmospheric environment, it is found that there are defects such as tiny pores or sand holes, and the quality consistency and stability are difficult to guarantee, which is not enough to meet the use requirements of the watertight connector in the deep sea environment.
Therefore, the use of vacuum vulcanizers to solve the technical problems of the vulcanization process of full-sea deep watertight connectors with inserts and other rubber products has no relevant information and reports.

Embodiment 1
[0034] In this embodiment, the titanium alloy shell with inserts and copper contacts are combined with rubber to make a full-sea deep watertight socket. The vacuum vulcanization process adopted is as follows:
[0035] 1. The inner wall of the titanium alloy shell 12 needs to be potted and the outer parts need to be vulcanized to be sandblasted. Protect the parts that do not need sandblasting with 3M adhesive tape, and then carry out sandblasting treatment in the sandblasting machine with the shell in hand. It is required that each part is sandblasted evenly. The mesh number of sand grains is 20 mesh, and the sandblasting time is 5 minutes.
[0036] 2. Clamp the copper contact piece 11 on the bench drill, and remove the gold-plated layer with a flat file. It is required to remove all the gold-plated layer on the adhered surface without obvious "bright spots", then tin-plate the inner wall of the solder cup, and use a flat plate for the excess solder File away.
[0037] 3. Grin...

Abstract
The invention discloses a vacuum vulcanization preparation process of a full-sea deep water-tight connector, and belongs to the technical field of preparation of full-sea deep water-tight connectors. According to the process, a vacuum vulcanizing machine is adopted, a watertight connector needing vacuum vulcanization is put into a mold cavity for mold closing after being subjected to surface treatment, wire welding, gluing and other procedures, a proper amount of rubber compound is put into a feeding tank placed at a rubber injection opening of an upper mold, and the rubber compound and the mold are placed on a lower flat plate of the vacuum vulcanizing machine together; after vacuumizing time, pressurizing time, pressurizing speed, pressurizing pressure, dwell time and dwell pressure are set, an upper flat plate and a vacuum cover of the vacuum vulcanizing machine descend, pressurizing glue injection and vacuumizing are carried out at the same time after the vacuum cover is completely sealed, vacuum vulcanizing is started, the vacuum cover and the upper flat plate automatically rise after the dwell time is up, and vacuum vulcanizing is finished, and the mold is opened, so that the product can be taken out. The process is convenient to operate and wide in application range, and can be suitable for various full-sea deep water tight connectors and other occasions where vacuum heat vulcanization is needed for rubber products.
Description
technical field [0001] The invention relates to the technical field of preparation of full-sea deep watertight connectors, in particular to a vacuum vulcanization preparation process for full-sea deep watertight connectors. Background technique [0002] The full sea deep watertight connector can meet the needs of power supply and large data flow in the deep sea environment. It is one of the key supporting components of the deep sea manned, unmanned submersibles and other marine technology equipment. It is of great importance for deep sea exploration and deep sea development. And widely used. In the past, before thermal vulcanization of watertight connectors, it was necessary to roughen and degrease the surface to be bonded by sand blasting, and then apply primer for thermal vulcanization. After the surface of the rubber layer is dry, heat vulcanization treatment is carried out with an ordinary flat vulcanizer. Before thermal vulcanization, the mixed rubber needs to be re-m...
