Abstract
An oil resistant sealing ring for diesel engine is characterized by comprising the following components in percentage by weight: 20 to 30% of cis-polybutadiene, 10 to 15% of polyisobutene, 10 to 15% of coumarone, 10 to 15% of resin, 10 to 15% of pyrolysis oil, and 5 to 10% of microbe. The sealing ring can achieve high efficient sealing.
Description
Technical field
The invention belongs to Diesel Engine Technique Field, be specifically related to the grease proofing sealing-ring of a kind of use for diesel engine.
Background technology
Reacting by sucking air of diesel engine, and important in cavity sealing very, and prevent diesel oil from leaking and cause catching fire, what adopt at present is the mode of being stained with glue, and the sealing of isomorphism sealing-ring, conventional seals circle cannot keep for a long time.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of this invention is to provide the grease proofing sealing-ring of a kind of use for diesel engine, there is high leakproofness, and do not account for the feature of oil.
Realize above-mentioned purpose for reaching, technical scheme of the present invention is as follows:
The grease proofing sealing-ring of a kind of use for diesel engine, is characterized in that, comprise following composition in mass ratio:
Cis-1,4-polybutadiene rubber 20-30%, polyisobutene 10-15%, ancient Malong 10-15%, resin 10-15%, row separate oily 10-15%, microorganism 5-10%.
Described resin is thermoplastic synthetic resin.
By technique scheme, the invention has the beneficial effects as follows:
The present invention by adopting compound, and coordinates microorganism to reach efficient sealed.
Embodiment
Below in conjunction with concrete enforcement, the present invention is described further.
