Description
技术领域
本发明属于高分子材料领域，具体涉及一种阻燃ASA材料，特别涉及一种低成本高流动耐候环保溴系阻燃ASA材料及其制备方法与应用。
背景技术
ASA树脂是由苯乙烯、丙烯酸酯、丙烯腈组成的三元接枝共聚物，以聚丙烯酸酯为主链，用丙烯腈、苯乙烯单体接枝共聚形成的非结晶聚合物。ASA由德国的BASF公司于1962年首次实现工业化生产，随后日本日立化成也实现了工业化。
由于ASA树脂采用了无双键结构的聚丙烯酸酯替代了ABS中聚丁二烯橡胶，因此成为塑料中耐候性最好的品种之一，其耐候性比ABS树脂高10倍以上。但ASA树脂本身也属于易燃材料，因此同ABS树脂一样，在用于电子电器设备时，需要进行阻燃改性，以达到安全防火使用要求。目前对热塑料性树脂的阻燃改性最有效、成本最低的方法是通过添加超过20%以上的溴系阻燃剂和锑系阻燃协效剂的复合物。由于ASA树脂本身因其耐候性优异而大多数用于户外的电子电器领域，因此如此多的溴系阻燃剂的加入会导致其耐候性恶化严重，失去了其优异耐候性特点。如中国专利CN101397391公开了四溴双酚A和三氧化二锑作为ASA树脂阻燃改性用的阻燃剂，但四溴双酚A的耐候性及耐热稳定性均较差，其加到ASA树脂中会导致ASA树脂的耐候性降低，热稳定性下降。中国专利CN101765635A公开了溴化环氧作为阻燃剂的ASA改性树脂，由于溴化环氧的耐候性和耐热稳定性均好于四溴双酚A，但溴化环氧树脂软化点只有90度左右，在共混挤出过程中容易结块，影响计量系统，并进而影响最终产品的阻燃稳定性及力学性能。中国专利CN102002203A公开了三（三-溴苯基）氰尿酸酯阻燃剂应用于ASA阻燃改性，该阻燃剂较好的保持了ASA树脂的机械强度，耐候性和热稳定性均好于相同阻燃体系的阻燃ABS产品，但由于其和锑系阻燃剂的总添加量为20%左右，如此多的添加量导致耐候性有一定程度的恶化，而且该体系的流动性一般，在成型薄壁和大尺寸制件中并不是最佳选择。同时，由于ASA树脂本身价格比较高，如此多的溴-锑复合阻燃剂的加入导致其成本的进一步提高，难以在市场上推广应用。
