The nitrile rubber sheet has good oil resistance and is not prone to swelling problems in oil media, and can maintain good performance for a long time. With the continuous improvement in the performance requirements of oil-resistant rubber sheets and the emergence of other polymer materials, the production methods of nitrile and oil-resistant rubber sheets have gradually diversified. Although oil-resistant rubber sheets produced using nitrile rubber alone still occupy the main market, some markets have been Instead of nitrile rubber/reclaimed rubber oil-resistant rubber sheet, nitrile rubber-plastic oil-resistant rubber sheet and other products, what production methods can be used for nitrile oil-resistant rubber sheet?
1. Use nitrile rubber alone
The nitrile rubber produced by emulsion polymerization of butadiene and acrylonitrile has excellent oil resistance and high abrasion resistance. It is an ideal raw material for the production of oil-resistant rubber sheets. The oil resistance of nitrile rubber is directly related to the content of acrylonitrile. The higher the content of acrylonitrile 2LLYY812, the better the oil resistance of nitrile rubber; therefore, rubber products manufacturers need to choose nitrile with the appropriate acrylonitrile content according to the oil resistance requirements of oil resistant rubber sheets. rubber.
2. Nitrile rubber + neoprene
The chloroprene rubber made from chloroprene monomer has high initial viscosity, high bonding strength, good elasticity, oil resistance, water resistance, alkali resistance, acid resistance, solvent resistance, flame resistance, and ozone resistance. It can be used with nitrile rubber to produce oil-resistant rubber board. Tests show that after using neoprene in the nitrile oil-resistant rubber sheet formulation, the heat resistance and chemical resistance of the oil-resistant rubber sheet are significantly improved, and the rubber sheet has better impact resistance. From the performance point of view, the use of neoprene in proper amount of nitrile oil-resistant rubber sheet is an ideal way to produce oil-resistant rubber sheet.
3. Nitrile rubber + renewable resources
The high price of nitrile rubber will bring great cost pressure to rubber sheet manufacturers, especially small and medium-sized enterprises. Therefore, more oil-resistant rubber sheet manufacturers have begun to use renewable resources in nitrile and oil-resistant rubber sheets to reclaim rubber and Mainly rubber powder. In actual production, nitrile rubber can be used with appropriate amount of nitrile reclaimed rubber or tire reclaimed rubber to produce oil-resistant rubber sheet, or add appropriate amount of nitrile rubber powder to fill nitrile oil-resistant rubber sheet, while ensuring the oil resistance of oil-resistant rubber sheet Reduce more raw material costs.
4. Nitrile rubber + plastic
The rubber-plastic blending technology is becoming more mature, and the nitrile oil-resistant rubber sheet can be processed by rubber-plastic blending. In actual production, nitrile rubber can be blended with PVC or PE to produce oil-resistant rubber sheet. PVC is polyvinyl chloride. It has good mechanical properties, electrical insulation properties, and chemical stability. It can improve the oil resistance and vulcanization properties of nitrile oil-resistant rubber sheets. PE is polyethylene, which has excellent low temperature resistance and good chemical stability. The appropriate amount of PE material in the nitrile oil-resistant rubber sheet formulation can significantly improve the low temperature performance of the rubber sheet.
5. Nitrile reclaimed rubber
Nitrile reclaimed rubber processed from waterlogged nitrile, nitrile waste rubber or waste nitrile rubber products retains the specific basic properties of nitrile rubber, low price and excellent oil resistance. High rubber content of nitrile reclaimed rubber can be used directly Instead of raw nitrile rubber to prepare oil-resistant rubber sheet; nitrile reclaimed rubber sheet has low production cost and long service life. In actual production, in order to further improve the comprehensive performance of reclaimed rubber and oil-resistant rubber sheets, rubber product manufacturers can choose to use nitrile reclaimed rubber together with a small amount of nitrile virgin rubber.
The oil-resistant rubber sheet processed by different production methods has its own unique advantages, or better oil resistance, or higher mechanical strength, or high temperature stability, or low production cost. Different production methods require different processing techniques. , Later editors will continue to share with you the issues that need attention in the production process of nitrile and oil-resistant rubber sheets and various production techniques.
