Abstract

The invention discloses an anti-stretch rubber seal ring material and a preparation method thereof. The anti-stretch rubber seal ring material is composed of the following raw materials: high impact polystyrene, nano white carbon black, anti-aging agent RD, insoluble sulfur, 3-aminopropyl trimethoxy silane, zinc dialkyl dithiophosphate, modified zinc oxide, diisobutyl phthalate and coco fatty acid diethanol amide. According to the invention, high impact polystyrene is used as the main material and has cheap price, excellent impact resistance and excellent anti-stretch performance, moreover, modified zinc oxide is also added in the raw material, thus, internal binding force of the rubber seal ring can be enhanced, and the properties of the rubber seal ring, such as stretch resistance, high temperature resistance, metal cohesive property and mechanical property, are improved effectively.
