Description

一种废旧聚苯乙烯泡沫塑料的新应用
技术领域
本发明涉及一种废旧聚苯乙烯泡沫塑料的新应用，采用低毒、价廉工业级溶剂在常温下对废旧聚苯乙烯泡沫塑料充分溶解后做为基料，再加入乳化剂、防冻剂、固体填料、改性剂和颜料等制取涂料，此项目属于工业化工领域。
背景技术
塑料是三大合成材料之一，种类繁多，主要有乙烯、聚丙烯、聚丙乙烯、和树脂等，不同的品种，其废弃物降解的产物也不同。处理废弃塑料的方法很多，如堆积掩埋法、焚烧处理法、光生物分解塑料等。塑料具有抗腐蚀能力强，不与酸、碱反应；制造成本低，耐用、防水、质轻等优点，但由于塑料的无法自然降解性，燃烧处理时又会产生有毒气体，回收利用十分困难，而且经济上不合算，现在已成为人类的第一号敌人。
本发明涉及一种废旧聚苯乙烯泡沫塑料的新应用，通过对回收的废旧聚苯乙烯泡沫塑料采用工业处理制取涂料，有效的解决了塑料处理的难题，并且制取出的涂料具有价格低廉、附着力好、耐酸碱、不易退色及不污染环境的优点，可广泛用于外墙涂料。
发明内容
本发明公开了一种废旧聚苯乙烯泡沫塑料的新应用，旨在提供一种将废旧聚苯乙烯泡沫塑料转化为涂料的一种方法，其步骤为：1）对回收废旧聚苯乙烯泡沫塑料进行预处理，将需清洗的聚苯乙烯连同热碱水一同加入反应釜中，加热并充分搅拌，之后取出聚苯乙烯放入清水池中进行搅拌清洗,达到除污目的；2）用粉碎机粉碎，量小的话手工粉碎；3）按一定的比例量取乙酸异戊酯、三氯甲烷、丙酮配制成混合溶剂。在室温条件下将一定量的预处理后的废聚苯乙烯泡沫塑料加入到配制好的混合溶剂中，搅拌使之充分溶解；4）待全部溶解后，加入适量的乳化剂十二烷基苯磺酸钠，改性剂，增塑剂邻苯二甲酸二丁酯1-3；防冻剂乙二醇，加热搅拌，温度为70~75，乳化1~2h；5）加入填料氧化锌或其它填料，加热搅拌大约1h，直至涂料均匀，冷却至室温，加入适量防老剂，过滤即得成。
