Description

一种无卤阻燃增强PA66材料及其制备方法
技术领域
本发明涉及高分子材料技术领域,尤其涉及一种断路器外壳用无卤阻燃增强PA66材料及其制备方法。
背景技术
PA66又称尼龙66(聚己二酸己二胺),半透明或不透明乳白色结晶形聚合物,具有可塑性。密度1.15g/cm3,熔点252℃,脆化温度-30℃,热分解温度大于350℃,连续耐热80-120℃,平衡吸水率2.5%。能耐酸、碱、大多数无机盐水溶液、卤代烷、烃类、酯类、酮类等腐蚀,但易溶于苯酚、甲酸等极性溶剂。具有优良的耐磨性、自润滑性,机械强度较高。但吸水性较大,因而尺寸稳定性较差。
目前,玻纤增强PA66具有优异力学性能,尺寸稳定性较佳,是一种应用非常广泛的增强工程塑料,广泛用于制造机械、汽车、化学与电气装置的零件,然而,其阻燃性能不能满足电子电器行业的需求。添加大量普通的卤锑阻燃剂,虽然在一定程度改善了材料的阻燃性,但是材料的力学性能和电绝缘性能都受到很大影响,比如相比漏电起痕指数(CTI)从600下降到250甚至更低,直接影响了材料在电子电器行业的应用。而随着环保要求的提高,传统的溴系阻燃剂已经不能满欧盟ROHS及WEEE指令的要求
发明内容

a:按重量配比称取PA66树脂,高填充红磷母粒,CTI改性剂,防腐抑蚀剂,相容增韧剂,抗氧剂,润滑剂,混合均匀,得混合原料;
b:将上述混合原料倒入双螺杆机料筒中,调整螺杆转速及主喂料速度加入无碱长玻璃纤维,挤出,造粒,获得无卤阻燃增强PA66粒料。
优选的,步骤b中的工艺条件为:一区喂料段温度260~290℃,二区压缩段温度为260~280℃,三区计量段温度250~280℃,四区机头温度270℃,螺杆转速为550RPM。
优选的,所述混合原料在主喂料口加入,无碱长玻璃纤维在侧喂料玻纤口加入,双螺杆挤出机的螺杆的长径比为40。

性能测试:
上述实施例按ASTM标准注塑成型成各种标准力学性能测试样条,按美国UL标准注塑成标准燃烧试样条,如表1所示
表1

实施例1~3配方及材料性能见表2:
表2
Figure BDA0000096239960000062
Figure BDA0000096239960000071
从表2可以看出,本发明中随着玻纤含量增加材料的拉伸强度和弯曲强度呈线性增加,在达到相同阻燃性能(UL94VO)条件下,红磷阻燃母粒的添加量相应可线性减少,相比漏电起痕指数(CTI值)也相应提高,而对材料的缺口冲击强度影响较小。
本发明中选用红磷母粒作为阻燃剂,阻燃30%玻纤增强改性PA66应用于断路器外壳的CTI值高达450V,而市场大部分同类材料的CTI值仅可达到400V左右,同时采用的改性手段并未引起材料力学强度的损失,而且通过添加防腐抑蚀剂能明显改善注塑过程中材料对模具的腐蚀性。该材料性价比高,不但实现了低添加量、高效阻燃、高CTI值,且通过加入抑蚀剂,降低了材料对金属的腐蚀性,从而拓展了材料的应用领域,延长了产品的使用寿命,满足电子电器应用领域的新要求。
以上对本发明所提供的一种无卤阻燃增强PA66材料及其制备方法进行了详细介绍,本文中应用了具体个例对本发明的原理及实施方式进行了阐述,以上实施例的说明只是用于帮助理解本发明的方法及其核心思想;同时,对于本领域的一般技术人员,依据本发明的思想,在具体实施方式及应用范围上均会有改变之处,综上所述,本说明书内容不应理解为对本发明的限制。
