preparation example Construction

[0045] The embodiment of the present invention relates to a method for preparing a watertight connector, which includes two parts, one is the preparation of a composite rubber material, and the other is forming the watertight connector. Mixed neoprene can be obtained by banburying and kneading the raw materials, and then the pretreatment of wires and cables is put into the mold for vulcanization. Therefore, it has the characteristics of simple preparation process and is convenient for practical popularization.

[0046] Specifically, the raw materials of the composite rubber material in the embodiment of the present invention include: chloroprene rubber, tackifier masterbatch 3, modified talcum powder, insoluble sulfur, zinc oxide, magnesium oxide, anti-aging agent, processing aid and accelerator; The composition of the masterbatch is neoprene rubber, terpene resin, and talcum powder.

[0081]

[0082] According to the above ratio, add neoprene Baypren711 into the internal mixer, add tackifier masterbatch, stearic acid, anti-aging agent and other processing aids in turn, then add magnesium oxide, add carbon black and modified talcum powder in batches , adding zinc oxide, sulfur and accelerator DBTU. After the mixing of rubber materials is completed, the material is discharged with an open mixer. Adjust the roller distance of the open mill to the minimum, thin it 5 times, gradually increase the roller distance, discharge and unload the sheet, stop the machine, cool to room temperature, and prepare the mixed neoprene rubber.

[0083] Part of the mixed neoprene was vulcanized on a flat vulcanizer, and samples were taken out to test its mechanical properties. The test results are shown in Table 2.

Abstract

The invention relates to the field of watertight devices, and particularly relates to a preparation method of a watertight connector, a product thereof and a composite rubber material for preparing the watertight connector. The preparation method of the watertight connector comprises the steps of preparing a composite rubber material and forming the watertight connector. The watertight connector has good watertightness, insulativity and pressure resistance, current deep sea coverage is met, and stable electric transmission use requirements are met.

Description

technical field [0001] The invention relates to the field of watertight devices, in particular to a method for preparing a watertight connector, a product thereof and a composite rubber material for preparing the watertight connector. Background technique [0002] Watertight connectors are also called watertight connectors. As one of the important components for the normal operation of underwater equipment, watertight connectors are currently used in a wide range of applications, including underwater construction machinery, operating equipment, underwater lighting, underwater power distribution systems, diving assembly devices, and offshore oil production platforms. And seabed observation network and other fields. [0003] Due to the late start of the development of watertight connectors in my country, there is a considerable gap with Western watertight connector technologies. There are no fixed model series of products, unstable process flow, failure to reach the level of ...
