Description
Technical field
The present invention relates to a kind of rubber raw materials, specifically a kind of ozone-resistant nitrile rubber sealing ring raw material.
Background technique
Nitrile rubber relies on its outstanding oil resistivity, and it is soft to be widely used in oil sealing, defeated (adding) oily hose, crankcase ventilation
The rubber products such as pipe, air filter air-out hose, however as most alkadiene rubber, due to unsaturated C=C double bond
In the presence of nitrile rubber is exposed in environment ozoniferous, easily generation crack phenomenon.The presence of acrylonitrile group (C ≡ N) simultaneously
It assigns nitrile rubber outstanding oil resistivity, makes it that there is good performance in Sewage Environment.But it is a large amount of in present sewage treatment
It is handled, such as hospital sewage, using ozone treatment energy, can in a few minutes be killed bacterium, therefore ozone exists using ozone
It is largely used in sewage treatment, and nitrile rubber is easily broken under ozone environment.
