Abstract

The invention discloses a high-performance shaft-end O-shaped rubber sealing ring. The high-performance shaft-end O-shaped rubber sealing ring is prepared from the following raw materials in parts by weight: 30-45 parts of tetra-propylene fluorine rubber, 15-25 parts of acrylonitrile-butadiene rubber, 20-40 parts of polyether urethane rubber, 20-40 parts of isoprene rubber, 2-5 parts of 1,1-di-(tert-butylperoxy)-3,3,5-trimethylcyclohexane, 0.5-1.5 parts of 1,2-polybutadiene, 1-1.8 parts of trimethylolpropane triacrylate, 45-55 parts of modified nano-montmorillonite, 20-40 parts of white carbon black, 5-15 parts of polytetrafluoroethylene fiber, 5-15 parts of carbon fiber, 5-15 parts of nano-kaolin, 5-10 parts of calcined clay, 10-20 parts of nano-calcium carbonate, 0.8-2.8 parts of isopropyl tri(dioctylpyrophosphate)titanate, 0.5-2 parts of triphenyl phosphate, 0.5-2 parts of dibutyl phthalate, 0.5-2 parts of microcrystalline wax and 1-1.8 parts of anti-aging agent.

Description

technical field [0001] The invention relates to the technical field of sealing rings, in particular to a high-performance shaft end O-shaped rubber sealing ring. Background technique [0002] The engineering requires high sealing performance. If the sealing ring fails, it will cause problems such as air leakage and liquid leakage, which will directly affect the operation of the entire machine. For the sealing between rotating parts, the O-shaped rubber sealing ring is used because of its low cost and structure. The advantages of simplicity and easy installation have been widely used. Since the seal at the shaft end is a dynamic seal, the shaft sleeve rotates with the shaft, and there is friction between the seal ring, and the seal ring is prone to stress relaxation. At the same time, the internal air pressure and oil pressure when the equipment is running The O-ring at the shaft end is prone to compression permanent deformation and hot air aging, and has higher requirements ...
