Nitrile renewable rubber oil, wear-resistant, can produce a variety of oil resistance, wear resistance of rubber products for a long time in the oil medium can also maintain the same properties; However, if the renewable nitrile rubber products in the Under the action of ozone, the stability of the product will be severely damaged, which will affect the serviceability and service life of recycled rubber products. In order to improve the ozone resistance of reclaimed rubber products, it is necessary to add a certain amount of antioxidant in the product formula.
As nitrile rubber reclaimed rubber products susceptible to ozone erosion, for some long-term exposure to the outside of the nitrile rubber reclaimed rubber products to choose anti-aging anti-aging system based on anti-aging agent, such as antioxidant 4010, antioxidant 4010NA, which antioxidant 4010 is A highly effective antioxidant that provides excellent protection against flex fatigue caused by ozone, wind erosion and mechanical stress (4010 can not be used in light colored nitrile rubber products because of the change of migration and color in the air). Anti-aging agent 4010-based anti-aging system can also be used with one or two paraffin to reduce rubber products in contact with ozone in static conditions, to extend the service life.
Nitrile renewable rubber anti-aging system, in order to improve the performance of nitrile rubber reclaimed products to extend the service life, you can also add appropriate anti-fatigue agents such as antioxidant H, or antioxidant Oxygen antioxidant D, antioxidant RD. Antioxidant H can enhance the protective effect of rubber products on hot oxygen, ozone, copper, iron, manganese and other harmful metals, and improve the tear strength and flex cracking resistance of nitrile reclaimed rubber products; Nitrile renewable rubber products can not only be used as antioxidants, but also can be used as lubricants, polymerization inhibitors; antioxidant RD on the heat and oxygen caused by the protective effect of aging very.
The use of butyronitrile reclaimed rubber production of light-colored rubber products, the need to choose non-pollution-type antioxidant 2246, antioxidant 264, antioxidant MB, etc., of which antioxidants 2246 belong to phenolic antioxidants, thermal oxygen, weather aging, Flexing aging and the price of metal has a good protective effect; antioxidant 264 can delay or inhibit the oxidative degradation of rubber products, extended nitrile rubber products renewable life; antioxidant MB to prevent including nitrile rubber products, including a variety of natural rubber , Synthetic air aging products, especially for a variety of light-colored, color, transparent, translucent rubber products.
Different nitrile rubber reclaimed rubber products cause aging reasons vary, so according to the use of environmental and performance needs to select the appropriate anti-aging system, one or more anti-aging agent and use, to improve the overall performance of nitrile rubber products, extend the use of time.
