摘要： The invention relates to expandable butyl rubber bladders for use in curing presses for hydrocarbon rubbers such as pneumatic tires. The bladders are a crosslinked elastomer comprising isobutylene repeat units and the bladder composition contains lecithin, particularly a modified lecithin, preferably in liquid form, dispersed within the bladder composition. The bladder composition may also contain castor oil, corn oil and/or soya-bean oil. The bladder composition may also contain at least one of graphite and polytetrafluoroethylene powder. The invention also relates to a method of curing tires by utilizing such butyl rubber bladder.

摘要： Expandable bladders for use in curing presses for hydrocarbon rubbers, such as pneumatic tires, are a crosslinked elastomer composition comprising isobutylene repeat units and including a fluorinated ethylene polymer added in particulate form and thereafter dispersed throughout the bladder. These fluorinated ethylene polymer may or may not form fibers. The bladders may further comprise graphite. A preferred isobutylene elastomer is a brominated copolymer of from 80 to 99 weight percent isobutylene and from 1 to 20 weight percent paramethylstyrene. The bladders have enhanced lubricity, reduced adhesion to cured tire innerliners, better resistance to cracking during flexing, and have lower tension set than similar compositions without fluorinated ethylene polymers. The above enhancements allow hydrocarbon rubbers such as tires to be molded with fewer defects caused by abraded or deformed bladders. They also enhance the useful life of the bladder reducing the cost of tire curing.
摘要翻译： 用于碳氢化合物橡胶（例如充气轮胎）的固化机的可膨胀气囊是包含异丁烯重复单元并且包括以颗粒形式加入并随后分散在整个气囊中的氟化乙烯聚合物的交联弹性体组合物。 这些氟化乙烯聚合物可以形成或不形成纤维。 气囊还可以包括石墨。 优选的异丁烯弹性体是80至99重量％异丁烯和1至20重量％对甲基苯乙烯的溴化共聚物。 气囊具有增强的润滑性，降低对固化的轮胎内衬的粘附性，在弯曲期间更好的抗开裂性，并且具有比没有氟化乙烯聚合物的类似组合物更低的张力设定。 上述增强使得诸如轮胎之类的烃橡胶被模制成具有由磨损或变形的气囊引起的较少缺陷。 它们还增强了膀胱的使用寿命，降低了轮胎硫化的成本。
