Benefits of technology

This patented technology improves upon existing rubber oils used during environmental protection applications such as those described earlier. It achieves this through long periods of exposure without losing its effectiveness or causing damage over time due to changes caused by external factors like weather conditions. Additionally, these new materials have better properties than older ones when exposed to harsh environments where they may be affected more easily compared with old designs.

Problems solved by technology

This patented technical problem addressed in this patents relates to developing better materials for use in various industries like vehicles due to factors including improved durability against rustiness (corrosiveness), reduced weight without compromising on functionality. Additionally, while being able to prevent leaks during operation, they should still maintain effective separation between different areas within the system where the material operational functions are performed.

Abstract

The invention belongs to the technical field of rubber framework oil-sealing production, and relates to an environmentally friendly anti-high and low temperature rubber oil-sealing material and a preparation method thereof. The preparation method comprises the following steps: 1) weighing the following raw materials in parts by mass: nitrile rubber, carbon fiber powder, zinc oxide, iron oxide, cerium oxide, stearic acid, sulphur, carbon black, dibutyl phthalate, dicapryl phthalate, oxidized polyethylene, a carbon black dispersant, 4-aminodiphenylamine, 2,2-disulfbenzothiazole, tetraethylthiuram disulfide, tellurium diethyl dithiocarbamate, a silane coupling agent, and a mold lubricant, placing the raw materials in an open mill and uniformly mixing the raw materials, blanking and placing a mixture overnight; 2) placing an overnight rubber compound in the open mill and re-milling the material, and obtaining the sheets; 3) after the rubber compound is preformed, placing the preformed rubber compound and a metal framework coated with an adhesive at an edge part in a sulfuration die together for sulfuration; and 4) performing steps of trimming, examination, packaging and warehousing. The environmentally friendly anti-high and low temperature rubber oil-sealing material belongs to environment friendly-type sealing, and has excellent oil resistant performance and high/low temperature-resistant performance.
