Embodiment 1

[0017] Embodiment 1: Heat-resistant and ozone-resistant rubber sealing ring material, the parts by weight (kg) of the raw materials are: chlorinated butyl rubber CBK-139105, precipitated silica 22, anti-aging agent ODA3.2, accelerator M0. 9. Methyltriethoxysilane 4.2, hydroquinone 1.9, modified bentonite 4.5, chlorinated paraffin 1.0 and dispersant NNO1.6.

[0018] The preparation method of heat-resistant ozone-resistant rubber sealing ring material comprises the following steps:

[0019] (1) Preparation of modified bentonite:

[0020] a: Weigh 16kg of bentonite, 5kg of iron ore tailings, 3kg of aluminum nitride powder, 4kg of mica powder, and 7kg of loess, mix them evenly, and sinter for 5 hours at a controlled temperature of 600°C, crushing for use;

[0021] b: Add the pulverized mixture of the above step (a) into an anhydrous ethanol solution for 3 hours, remove it, and dry it at 55°C;

[0022] c: Add 2.2kg of aminopropyltriethoxysilane, 5.0kg of terephthalate and 2.0kg o...

Abstract

The invention discloses a heat-resistant and ozone-resistant rubber sealing ring material and a preparation method thereof. The rubber sealing ring material is prepared from the following raw materials: chlorinated butyl rubber CBK-139, white carbon black obtained by a precipitation method, an anti-aging agent ODA (bis(4-octylphenyl)amine), an accelerant M, methyl triethoxysilane, hydroquinone, modified bentonite, chlorcosane and a dispersing agent NNO. The chlorinated butyl rubber CBK-139 used as a main material is low in price and good in heat resistance and flexing resistance; the modified bentonite is added into the raw materials, so that the inner bonding force of a rubber sealing ring is enhanced. As a result, the tensile resistance, high-temperature resistance, metal bonding property, mechanical property and the like of the rubber sealing ring are effectively improved.
