Butyl rubber is the best raw material for the production of inner tube products, but the higher the butyl rubber price and sometimes tight supply, so more and more rubber products manufacturers have begun to add a certain amount of butyl inner tube butyl rubber reclaimed rubber instead Part of the butyl rubber, can reduce the cost of raw materials, but also ease the changes in the supply and demand of butyl rubber on the impact of manufacturers. The use of butyl reclaimed rubber and butyl rubber and the production of butyl inner tube can also improve the processing performance of butyl inner tube and prolong the service life of butyl inner tube to a certain extent.
The following is a small series to see a high-performance butyl tube formula, posted and we learn together:
Butyl rubber 85 parts butyl rubber 15 parts ethylene propylene rubber 15 parts carbon black 50 parts operating oil 23 parts vulcanization accelerator 3.2 other auxiliaries 10 Total: 201.2 parts.
This formula is mixed with butyl rubber reclaimed rubber to produce high-quality butyl inner tube typical formula, reclaimed rubber formulations with less dosage, can ensure that the butyl inner tube products have a high comprehensive index; formula and part of the three yuan B Propylene rubber can improve the aging of butyl rubber soft sticky phenomenon, extending the service life of butyl inner tube; butyl rubber reclaimed rubber is the product of processing of waste butyl inner tube, the production process through multiple processes, excellent plasticity and liquidity Butyl rubber, butyl inner tube can improve the processing technology, saving labor; butyl inner tube using butyl rubber, butyl rubber and EPDM rubber production and use, both to reduce costs, but also can improve the butyl inner tube Performance, extend the service life.
The results show that the hardness of the butyl inner tube produced by this recipe is 50HA, the tensile strength is 11Mpa, the elongation at break is 760%, the permanent set at break is 34%, the tensile set at 300% is 2.7 and the tear strength is 46. National standard.
For the production of butyl inner tube manufacturers, the above formula can be used as a reference, the specific formula but also according to the needs of their own inner tube products appropriately adjusted in the temperature changes, the seasonal changes in the timely adjustment of butyl inner tube products recipe, that The age of "a recipe life" is long gone.
