Problems solved by technology

[0004] Traditional polymer elastic sealing materials such as nitrile polymer (NBR), acrylate polymer (ACM), and fluoropolymer (FPM) cannot meet the actual use of high temperature, high speed, and high wear resistance due to the linear speed they bear Working conditions, thus putting forward higher technical requirements for the sealing base material

Embodiment Construction

[0016]

[0017]

[0018] The above raw materials can be purchased from the market.

[0019] Among them: oil seal base material, as the basic raw material for oil seal manufacturing, its selection must consider the compatibility of the material to the working medium, the adaptability to the working temperature range and the ability of the lip to follow the rotating shaft when it rotates at high speed. The present invention adopts one or several kinds of hydrogenated nitrile polymer, polytetrafluoroethylene and styrene copolymer, and the relative ratio is arbitrary. Among them, the selected object of styrenic copolymer is styrene-ethylene / propylene-styrene copolymer.

[0020] Reinforcing fiber refers to a fibrous substance that can improve the mechanical strength of the polymer and the dimensional stability of the product, reduce the shrinkage rate or reduce the thermal deformation after compounding with the resin (polymer). In the present invention, it is suggested to us...

Abstract

The invention provides a wide-temperature-range high-speed fluid dynamic oil seal. The wide-temperature-range high-speed fluid dynamic oil seal comprises the following raw material components in parts by weight: 100 parts of an oil seal base material, 5 to 35 parts of reinforced fibers and 3 to 20 parts of a nano-filler. The wide-temperature-range high-speed fluid dynamic oil seal with an interpenetrating polymer network (IPN) structure is prepared from the oil seal base material serving as a base and the reinforced fibers and the nano-filler serving as auxiliary materials; expensive fluoropolymer and an acrylate adhesive with low process tolerance are replaced by a common base material, so that the production cost is effectively reduced; the prepared oil seal has appropriate oil expansibility and a good sealing effect, and by adopting the formed IPN structure, the adaptability of a finished product to high rotating speed, high and low temperatures and oil resistance working conditions, and the use reliability of the finished product are improved, the temperature resistance grade is between 35 DEG C below zero and 200 DEG C, and the transient temperature can reach 300 DEG C; and the linear speed of fluid at a sealing part reaches 20m / s, so that the soil seal product is good in product superiority and high in cost performance.

Description

technical field [0001] The invention relates to the field of rubber parts production, in particular to a wide temperature range high-speed fluid power oil seal and a manufacturing method of the oil seal. Background technique [0002] As an important part of mechanical basic parts, polymer seals are an important guarantee for the performance, quality, safety and reliability of various mechanical hosts. Whether it is transportation (automobiles, trains), construction machinery, mining machinery, environmental protection machinery and other industries, or major fields such as aviation and aerospace, rubber seals are inseparable and irreplaceable. [0003] Due to the harsh conditions of use, the oil seal has strict requirements on rubber materials. Currently used oil seal materials, in addition to nitrile rubber for ordinary occasions, special materials such as fluoropolymers, acrylic polymers, silicon polymers, fluorosilicon polymers, hydrogenated nitrile polymers, and polytet...
