Rubber material for rubber water seal and preparation forming method and equipment thereof

Abstract

The invention discloses a rubber material for a rubber water seal as well as a preparation forming method and equipment thereof. The rubber material comprises the following components in parts by weight: 100 parts of No.3 smoke sheet rubber; 14.6 to 15.0 parts of Fast extruding furnace black; 34.5 to 34.8 parts of high-wear-resistance carbon black; 14.6 to 15.0 parts of gas-mixture carbon black; 4.1-4.5 parts of zinc oxide, 2.0-2.2 parts of stearic acid, 1.8-2.1 parts of paraffin, 1.0 to 1.1 parts of an anti-aging agent RD; 2.8 to 3.1 parts of Vaseline, 0.6 to 0.8 part of an accelerant NOBS, 0.05 to 0.15 part of an accelerant D, 0.9 to 1.3 parts of an anti-aging agent 4010NA, 0.2 to 0.4 part of an anti-scorching agent CTP, 2.3 to 2.7 parts of sulfur S-80 and 19.5 to 22.0 parts of ethylenepropylene diene monomer rubber. During preparation and forming, the rubber material is preformed firstly, then a vulcanization mold is filled with the preformed rubber material, meanwhile, extension parts are arranged at one end or two ends of the vulcanization mold, only part of the vulcanization mold is vulcanized during vulcanization, and the extension parts are not vulcanized, so that vulcanization between raw rubber and raw rubber can be realized through vulcanization of a later joint part; and the vulcanization bonding strength of a rubber water seal joint is improved.

Description

technical field [0001] The invention relates to the field of production and on-site installation of rubber water seals for hydraulic metal structures, in particular to a rubber material for rubber water seals and a preparation method and equipment thereof, which can improve the strength and service life of rubber water seal joints. Background technique [0002] The rubber water seal is a key component to ensure the normal operation of the hydraulic metal structure and the water sealing effect. Therefore, the overall continuity of the rubber water seal product is extremely important, but whether it is in the rubber water seal production process or installed on the rubber water seal site In the process, there are inevitably joints, and the water seal joint is a relatively weak part of the whole rubber water seal product. Therefore, the quality of the water seal joint becomes a key part that affects the overall performance of the water seal. . According to testing and empirica...

AI Technical Summary

Problems solved by technology

In view of the actual working conditions at the installation site, heating and pressurization conditions, and the professionalism of the operators, it is difficult to achieve the desired effect on the actual strength of the hot vulcanized adhesive joints on site.
