Description
本发明是关于氟弹体的共硫化组合物。
更具体地说本发明是关于改善了化学稳定性的氟弹体共硫化组合物。
以1,1-二氟乙烯为基础,并根据双酚或二羟基体系硫化的氟弹体(Kirk-othmer,Encyclopaedia of chemical technology,第8卷,P506,1979)是很有价值的产品,该产品用于工业界,特别是用在汽车和石油工业领域,通常是用在能源工业领域内。
在汽车领域内,氟弹体主要被用于燃料循环系统或作为发动机部件以及齿轮箱差动变速装置的元件。
在第一种情况中,作为应用的例子可列举的有燃料泵用薄膜、阀座、止逆阀、可弯曲的软管以及通常所用的各种密封衬垫。
对于第二种情况,类似的例子是各种齿轮用垫片、各种柴油机中汽缸用密封衬垫、曲轴用垫片、排气用止逆阀、各种轴密封型垫片以及其他等等的使用。
在石油和能源工业领域内,氟弹体有各种应用。其中有的用来与原油直接接触。例如,用作衬垫阀和泵或它们的各种零部件,所有这些都是在高温高压下使用。
在该领域内,氟弹体有代表性的重要应用是用作热电厂中排废气管道的伸缩接头,其中需要既耐高温又耐酸性废气的腐蚀。
氟弹体之所以用于以上这些方面和电气、电子领域等其他方面。正是由于它们的热稳定性高和耐化学性好,尤其是在高温情况下。
但是这几年来,某些应用类型已提出了严格的技术要求,而现有的采用双酚或二羟基体系进行硫化的制造工艺已不能满足这些要求。
该问题特别涉及到在恶劣操作条件下的化学稳定性问题。此操作条件的特点是高温并存在蒸气、无机酸、SF系列油等浸蚀性高
的润滑液体,另外作添加剂用的一些化合物对基于1,1-二氟乙烯的氟弹体,有较高的溶胀能力。
此外,从混合物的加工特性考虑,对于模塑轴封零件以及使混合物容易挤压或合适的甚至是有复杂外形的半成品的可能性方面尚需要做一般性的改进。
由于采用过氧化物进行硫化,已经解决了化学稳定性。
然而,该硫化方式还不能满足上述加工性,尤其不能满足模压和挤压加工的要求;而且导致这些加工性能的可靠性较差,(Rubber Chemistry and Technology,第55卷,P906,1982),从而得到压缩变形试验数据很差的产品(Kirk-Othmer,在图书中的第510页)。
欧洲专利申请No,84,110707已制备并公开了共硫化的组合物,为了达到性能上的要求对化合物作了某些改进,但是加工可靠性仍较差,化学-热性能也有轻度下降。
本发明的目的是为了提供一种氟弹体的共硫化组合物,以使之克服上述缺陷。
