Abstract

The invention relates to a high-pressure-resistant pure-oxygen-resistant sealing member sizing material which comprises the following components in parts by weight: 100 parts of neoprene, 5 parts of ZnO, 1-2 parts of stearic acid, 1-4 parts of magnesium oxide, 1-3 parts of organic magnesium, 20-60 parts of white carbon black, 1-8 parts of curing agent, 1-5 parts of accelerator, 1-2 parts of auxiliary curing agent, 1-4 parts of auxiliary crosslinking agent and 1-2 parts of peroxide. A sealing medium of a sealing member manufactured from the high-pressure-resistant pure-oxygen-resistant sealing member sizing material can work and normally exert the sealability under the conditions that the high pressure is 150KG.F / mm<2> and the oxygen purity is 99.99%.

Description

technical field [0001] The invention belongs to the field of rubber, and relates to a neoprene rubber, in particular to a high-pressure-resistant and pure-oxygen-resistant seal material and a preparation method thereof. Background technique [0002] The sealing medium of general seals is mostly grease, and the ones with good sealing effect and high requirements are all made of nitrile rubber, the national standard GB / T1235.1-2008, but the current nitrile rubber cannot meet the conditions of high pressure and pure oxygen sealing. [0003] According to the search, the following patent documents related to this patent are found, and the specific disclosure is as follows: [0004] 1. A preparation method (CN102729481A) of a composite rubber film for pipeline sealing rings, comprising the following steps: (1) putting natural rubber into the storage box of a preforming machine, and controlling the extrusion speed of the preforming machine at 50-60r / min, the temperature of the mac...
