Abstract
The invention discloses a rubber seal ring and a preparation method thereof. The rubber seal ring is prepared from hydrogenated acrylonitrile butadiene rubber, high-wear-resistant carbon black, silica powder, an activating agent magnesium oxide, a lubricant microcrystalline wax, an accelerant, an anti-aging agent and a vulcanizing reagent in proportion through banburying synthesis, open mixing forming, secondary vulcanizing and trimming. The rubber seal ring has the characteristics of wear resistance, crack resistance, low compression deformation, oil resistance, high temperature resistance and long service life.
Description
Technical field:
The present invention relates to technical field of sealing technology, be specifically related to a kind of rubber seal and preparation method thereof.
Background technology:
Rubber seal of the prior art with nitrile rubber (NBR) for main raw material(s), because its oil-proofness is good, low cost of manufacture and widespread use.But such sealing-ring is when carrying out dynamic seal, as the seal parts such as axle and hydrauliccylinder piston of rotor pump, then often occur that sealing-ring sealing surface wear causes seal failure and sealing-ring that circumferential distortion occurs and causes leakage, namely sealing-ring wears no resistance, compression set is torn greatly, easily, work-ing life is short, Shortcomings.
Summary of the invention:
For above-mentioned deficiency, the invention provides a kind of rubber seal and preparation method thereof, have that wear-resistant and crack-resistant, compression set are low, the feature of oil-resistant high-temperature, long service life.
The present invention is achieved through the following technical solutions:
A kind of rubber seal, is formed by following composition by weight proportioning: hydrogenated nitrile-butadiene rubber: 60-65 part; High abrasion carbon black: 10-15 part; Silicon powder: 10-12 part; Promoting agent magnesium oxide: 6-8 part; Lubricant microcrystalline wax: 1-3 part; Vulcanization accelerator TMTD: 0.6-0.8 part; Anti-aging agent RD: 0.6-1.0 part; Vulcanizing agent: 1-3 part.
As choosing advantageously, described rubber seal is formed by following composition by weight proportioning: hydrogenated nitrile-butadiene rubber: 65 parts; High abrasion carbon black: 12 parts; Silicon powder: 10 parts; Promoting agent magnesium oxide: 7 parts; Lubricant microcrystalline wax: 1.5 parts; Vulcanization accelerator TMTD: 0.7 part; Anti-aging agent RD: 0.8 part; Vulcanizing agent: 3 parts.
The preparation method of described rubber seal is: first by Banbury mixer synthetic rubber, then after synthetic rubber is opened by mill the type of being smelt, then after post cure, by the rubber seal deburring of post cure, to obtain final product.
Compared with prior art, sealing-ring of the present invention has that wear-resistant and crack-resistant, compression set are low, the feature of oil-resistant high-temperature, long service life, is specially adapted to dynamic seal.
