Description

一种安全帽用阻燃抗静电ABS改性料及其制备方法
技术领域
本发明涉及高分子复合材料领域,具体是涉及一种安全帽用阻燃抗静电ABS改性料及其制备方法。
背景技术
ABS工程塑料(丙烯腈-丁二烯-苯乙烯树脂)是一种强度高、韧性好、耐化学性好、电绝缘性佳,易于加工成型的热塑性高分子结构材料,已成为安全帽帽壳的主流材料之一。但是,ABS工程塑料可燃(氧指数为21%),且易产生静电现象(表面电阻率为4.6×1015Ω·cm)。在井下、矿山等条件较为恶劣工况条件下使用ABS安全帽时,安全帽的阻燃和抗静电成为十分突出的问题。如何保证安全帽在具有足够抗冲击性能的前提下,又具有良好的阻燃和抗静电性能,是迫切需要解决的关键问题。
现有中国专利文献ZL2009101997914公开了用溴系和锑系阻燃剂、非离子和阴离子表面活性剂抗静电剂的阻燃抗静电ABS改性树脂。但是,用表面活性剂为抗静电剂很难达到持久抗静电的效果;小分子阻燃剂,尤其是卤系阻燃剂,不仅会影响ABS工程塑料的力学性能和加工性能,而且燃烧时会产生烟雾,这对于井下、矿山作业是十分有害的。中国专利文献CN102020285A公开了通过添加永久抗静电剂制备ABS复合材料,由于抗静电剂是聚醚酯、聚醚酰胺等,它们与ABS的相容性较差,虽然马来酸酐接枝ABS相容剂在一定程度上可以改善ABS与抗静电剂的相容性,但无法根本解决相容性导致该ABS复合材料用于安全帽时,无法达到安全帽的耐冲击强度等其他力学性能。其他中国专利文献,如ZL2012101287777,CN101463177A,CN101215403A等也分别公开了或阻燃、或抗静电的ABS改性树脂。但是,适应于安全帽用的既要达到耐高冲击强度,又要满足持久抗静电性能和无烟的优良阻燃性能的ABS改性树脂,还未见文献报道。
发明内容
本发明的目的是针对目前阻燃抗静电ABS改性料不能满足安全帽用工程塑料的现状,提供一种安全帽用阻燃抗静电ABS改性料,该ABS改性料用作安全帽材料,不仅具有持久的抗静电性能,而且达到无烟的阻燃效果,同时满足安全帽的力学性能要求。
为了实现上述发明目的,本发明采用如下技术方案:
一种安全帽用阻燃抗静电ABS改性料,其组成和各组成的重量百分比为:
Figure BSA0000101569890000011
Figure BSA0000101569890000021
进一步地,所述的相容剂是苯乙烯-马来酸酐-丁二烯共聚物,优选的是DOW公司的XP5272;
所述的抗静电剂是聚醚酰胺类高分子抗静电剂,优选的是法国阿科马公司的7233,或德国萨-赫斯公司的PA12;
所述的复合阻燃剂是由有机硅和锑酸盐组成,有机硅和锑酸盐的重量份为4~8:1,有机硅优选的是美国GE公司的SFR-100,或SFR-1000,锑酸烟是锑酸钠;
所述的加工助剂包括抗氧剂、热稳定剂等的一种或几种。
本发明的一种安全帽用阻燃抗静电ABS改性料的制备方法,包括以下步骤:
(1)将上述所述的重量百分比称取各组分,在高速混合机中混合均匀;
(2)将上述混合料经喂料器送入双螺杆挤出机,通过熔融、挤出、拉条、冷却、切粒,得到安全帽用阻燃抗静电ABS改性料;其中,双螺杆挤出机一区温度为120℃~140℃,二区温度为140℃~160℃,三区温度为160℃~180℃,四区温度为180℃~200℃,五区温度为200℃~210℃,六区温度为210℃~220℃,螺杆转速200r/min~300r/min,喂料转速30r/min。
与现有技术相比,本发明的安全帽用阻燃抗静电ABS改性料,具有如下突出优点:
(1)优选的聚醚酰胺类高分子抗静电剂,可与相容剂发生部分接枝反应,在保持持久的抗静电性能的基础上,确保了高分子抗静电剂的加入,不会造成安全帽的力学性能降低而产生的不利影响。
(2)优选的复合阻燃剂,一旦燃烧就会生成硅酮特有的、含有Si-O键和Si-C键的无机隔热绝缘保护层,既阻止了燃烧生成的分解物外逸,又抑制了高分子材料的热分解,达到了高阻燃化、低发烟量的目的。
(3)本发明的阻燃抗静电ABS改性料用于安全帽,符合国家GB2811-2007《安全帽》标准,其主要力学性能和抗静电阻燃性能指标如下表所示:
