Description

一种阻燃ABS组合物及其制备方法和应用 技术领域
本发明涉及一种工程塑料领域，更具体地，涉及一种阻燃ABS组合物及其制备方法和应用。
背景技术
ABS属于三元共聚物，其化学结构中含有聚丁二烯橡胶组份，具有易燃性，相比工程材料，其在燃烧过程中难以成炭，实现高等级阻燃性能具有较大技术难度。目前ABS材料常用作家用电器的外壳，这些产品在使用过程中会因过热、漏电、和老化等原因引起火灾，对人们的生命造成巨大威胁。阻燃ABS目前都可以实现V-0，V-1和V-2阻燃等级，但是只有V-2等级可以实现无卤阻燃，V-0等级目前只有溴系阻燃体系才可以实现，也就是有卤阻燃，溴系阻燃ABS材料在燃烧过程中会产生较大的烟雾及毒气，对人体健康会造成很大伤害，无卤阻燃体系在燃烧过程中产生的危害性较小，是未来阻燃材料的发展趋势，也一直成为研究的热点，但是目前能够满足无卤V-0阻燃ABS材料，都存在一些性能上的缺陷，比如力学性能差，限制了无卤阻燃ABS材料的应用。
中国专利(CN104968691A)公开了一种用于制备具有改善的表面的ABS组合物的方法，该专利虽然公开了磷系阻燃剂用来提高其阻燃，但是该组合物的力学性能的优劣并未可知。
因此，目前现有的ABS组合物存在无法同时保证无卤V-1阻燃等级以上和力学性能高的问题。
发明内容

从实施例1～4看，随着ABS树脂的增加，其缺口冲击强度略微上升，这是因为树脂的含量增多，聚丁二烯含量增多，所以缺口冲击强度增加。
从实施例2和6～8看，随着环状磷腈化合物的增加，其缺口冲击强度略微下降，这是因为环状磷腈化合物与ABS树脂相容性差，随着环状磷腈化合物的增加，其缺口冲击强度稍有下降。
从实施例2和9～11看，随着DOPO衍生物的增加，其缺口冲击强度略微下降，这是因为DOPO衍生物与ABS树脂相容性差，随着DOPO衍生物的增加， 其缺口冲击强度稍有下降。
从实施例12～14看，选择不同类型的环状磷腈化合物，为V-1阻燃等级，当R基团的-CH 3和-NH 2磷腈化合物的冲击强度要好于-F基团的磷腈化合物。
从实施例15～17看，选择不同DOPO衍生物，为V-1阻燃等级不变，但是当R基团的-CH 3和-NH 2的DOPO衍生物的冲击强度要好于R基团为对苯二酚取代基。
从对比例1～3看，当不添加环状磷腈化合物和DOPO衍生物时或者两者只添加其一，都不能满足V-0阻燃，从对比例4和5看，若环状磷腈化合物与DOPO衍生物的质量比高于3:1，其力学性能急剧下降；当环状磷腈化合物与DOPO衍生物的质量比低于1:1，其阻燃等级达不到V-2。
显然，本发明的上述实施例仅仅是为清楚地说明本发明所作的举例，而并非是对本发明的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明权利要求的保护范围之内。
