Nitrile reclaimed rubber is a reclaimed rubber processed from waste nitrile rubber products. It is the best oil resistant product in reclaimed rubber and is used in the production of various oil resistant rubber products. The use of nitrile rubber to produce rubber products sometimes adds a certain amount of natural rubber to the formula of nitrile reclaimed rubber. What is this? What problems should be paid attention to when producing nitrile rubber reclaimed rubber and using natural rubber to produce rubber products?
The main purpose of adding a small amount of natural rubber in the formulation of nitrile reclaimed rubber products is to improve the processing technology of nitrile reclaimed rubber and improve the use performance of reclaimed rubber products: The combination of nitrile reclaimed rubber and a small amount of natural rubber can play a role of plasticizing and increasing viscosity, improving Rubber processing performance; improve the low temperature resistance of nitrile reclaimed rubber products.
Since the compatibility of nitrile rubber reclaimed rubber and natural rubber is extremely low, the amount of natural rubber used should not be too high; the use of too much natural rubber in the formulation of nitrile regenerated rubber products will also lead to significant heat and oil resistance of nitrile reclaimed rubber. When it is lowered, the permanent deformation of compression is obviously increased; therefore, when using nitrile rubber reclaimed rubber and natural rubber in combination to produce rubber products, the blending amount of natural rubber must not exceed 15 parts. Only by controlling the amount of natural rubber and various additives can play the best role of nitrile reclaimed rubber, in the production of oil-resistant rubber products more time and effort, the production of rubber products to achieve the best performance.
The nitrile reclaimed rubber can not only be used together with natural rubber; it can be used together with styrene-butadiene rubber to improve the cold resistance of the product and reduce the cost of raw materials; it can also be used together with butadiene rubber, polyvinyl chloride, phenolic resin, etc. to improve the processing technology of nitrile rubber reclaimed rubber products. Use performance, expand the scope of use of nitrile reclaimed rubber.
In addition to the use of nitrile rubber reclaimed rubber, the main role is to replace nitrile rubber, or with nitrile rubber to produce high oil resistant rubber products significantly reduce costs. In actual production, due to the low compatibility of nitrile reclaimed rubber with other types of rubber, it is necessary to pay special attention and use proportions, especially when combined with natural rubber or other general-purpose synthetic rubber. When choosing nitrile reclaimed rubber, rubber product manufacturers must choose the product with suitable glue content and suitable acrylonitrile content according to the demand. For example, to produce cold-resistant rubber products, it is necessary to choose low-acrylonitrile nitrile reclaimed rubber.
