Description
技术领域
本发明属于高分子材料领域,具体涉及一种微孔发泡密封条,此种密封条可用于汽车、轮船、电器、门窗等各个领域。
背景技术
乙丙橡胶(EPDM)是由乙烯、丙烯以及少量的第三单体共聚而成的橡胶,他的主链上由化学稳定的饱和烃组成,只在侧链中含有不饱和双键,分子内无极性取代基,分子内聚能低,分子链段在较宽的温度范围内保持柔性。因而具有优异的化学稳定性、耐老化性、耐化学药品性,电绝缘性、冲击弹性和低温性能,以及耐热水性能。EPDM橡胶发泡材料可广泛应用于汽车的挡风条,缓冲胶垫,建筑工程用密封垫片,弱点部件的绝热材料、减震材料、简易的潜水服及鞋等制品。
乙丙橡胶/聚丙烯热塑性弹性体(EPDM/PP(TPV))综合了EPDM和PP的优点,即优异的耐臭氧老化性,电绝缘性以及良好的加工性能,是目前TPV中开发最成功的一种,而且在原料、性能及产品价格方面都具有竞争优势。与TPO和CR、EPDM相比,EPDM TPV的性能有以下主要特点;A.压缩永久变形比TPO大有改善,而且也优于EPDM和CR;B.耐油性优于TPO;C.耐侯性能和耐臭氧性能优异。TPV兼具有热塑性塑料加工便利性和热固性橡胶的高弹性,其比重小,成本低,材料可反复回收利用,耐臭氧、耐疲劳、耐高低温,密封性好,压缩永久变形小,耐油、耐溶剂特性显著。可用于汽车各类密封条/密封件,高压点火线、防尘罩、进气管、通风管、缓冲器、方向盘包皮,挡泥板等。
目前的汽车密封条生产采用的发泡配方,基本为化学发泡剂发泡,发泡孔不足、发泡孔不均匀,发泡孔过大,产品的硬度、密度不合标准,闭孔会变成联孔,微孔变成小孔,影响发泡质量,且压缩永久变型较大,会有发泡剂残留。因此,一种力学性能较好,无毒环保的汽车密封条的研制将会代替市面上传统的发泡密封条。
发明内容
本发明的目的是提供一种微孔发泡密封条,并以此提供了排放及其制备工艺,本发明解决了化学发泡密封条泡孔不均、力学性能欠佳、有化学残留等问题,真正意义上提供了一种环保、高强的微孔发泡密封条的制备工艺。
