NBR regeneration of the oil resistance, Xiaobian no longer emphasized. Now more and more rubber products manufacturers began to use nitrile rubber instead of nitrile rubber instead of raw rubber production of rubber products, oil damping block is one of them. Nitrile reclaimed rubber retains the nitrile rubber oil resistance, but due to the recycling of waste rubber resources, oil resistance in the process of loss. Therefore, the use of nitrile rubber reclaimed rubber production shock absorber block, the choice of nitrile rubber reclaimed rubber products and rubber damping block formula design is particularly important, high-quality products + reasonable formula design can offset the reclaimed nitrile rubber and nitrile rubber in Performance gap. The combination of nitrile rubber reclaimed rubber and acrylonitrile-butadiene rubber is the best way to ensure the quality and reduce the cost of oil-resistant shock absorber.
The following is a nitrile rubber reclaimed rubber and acrylonitrile-butadiene rubber used in conjunction with the production of high-index oil damping block formula:
Butyronitrile reclaimed rubber, 30 parts; sulfur powder, 1.5 parts; accelerator, 0.5 parts; accelerator DM, 1.5 parts; zinc oxide, 5 parts; stearic acid, 1 part; Strong carbon black, 27.5 parts; Wear carbon black, 15 parts; DBP, 25 parts; Antioxidant, 2 parts; Total: 179 parts.
The combination of nitrile rubber and acrylonitrile-butadiene rubber can increase the amount of rubber in the shock-absorbing block, improve the oil resistance of nitrile oil-resistant shock-absorbing block and prolong the service life of the product. At the same time, nitrile The price of reclaimed rubber is lower than that of acrylonitrile-butadiene rubber, and the use of butyronitrile reclaimed rubber to replace part of nitrile raw material can effectively reduce the cost of raw materials and enhance the market competitiveness.
Some people may have doubts, butyl rubber regeneration is excellent damping performance, then why not choose butyl rubber production shock absorber it? In fact, the problem is very simple, although the butyl rubber cushioning performance is good, but compared with the nitrile rubber oil resistance is still a big gap, if it is the production of oil-resistant damping block products, or the use of small Nitrile rubber and nitrile rubber reclaimed rubber the most appropriate; butyl rubber reclaimed rubber commonly used in the production of damping high damping products.
High-quality production of nitrile rubber reclaimed rubber production shock absorber can not only reduce the cost of raw materials to ensure product quality, but also can improve the anti-aging properties such as damping blocks, saving labor.
