Description

一种快速成型可发性聚苯乙烯生产方法
技术领域
本发明涉及一种快速成型可发性聚苯乙烯生产方法，应用于聚苯乙烯生产加工技术领域。
背景技术
聚苯乙烯泡沫塑料应用于电子电器缓冲包装材料、蔬菜水果包装箱、海上漂浮制品等领域中，市场上生产聚苯乙烯时，常常会出现反应釜内粒子粒径不均匀、不集中的情况，产品合格率较低的情况，造成在生产过程中蒸汽使用量较大，且生产周期较长，一定程度上增加了企业成本，降低了企业的经济效益。
发明内容
为解决上述的问题，本发明公开了一种快速成型可发性聚苯乙烯生产方法，由下列步骤组成：
1）将纯水100~120份加入反应釜中，开启搅拌后加入活性磷酸钙0.05~0.1份、磷酸三钠0.0001~0.0003份、十二烷基苯磺酸钠0.01~0.02份，转相后加入苯乙烯100份至反应釜内，再依次加入TBPB0.03~0.06份、DOP0.01~0.03份、DCP0.005~0.015份、甲苯0.15~0.3份、二甲苯0.2~0.4份、成核剂0.1~0.2份后搅拌均匀；
2）向反应釜设备夹套中通入蒸汽，缓慢升温；
3）55至65℃时加入BPO0.4~0.6份；
4）升温至88 至92℃后，恒温造粒，此过程时间4 ～6 小时；
5）加入分散剂磷酸钙0.1 ～ 0.15 份、灰钙粉0.1 ～ 0.2 份；
6）加入戊烷5~6份，通入蒸汽缓慢升温，升温至95 ～ 98℃后恒温反应1.5 ～ 2.5 小时；
7）升温至115 ～ 118℃后恒温反应3 ～ 3.5 小时, 温度控制在125 ～ 130℃，压力控制在0.8 ～ 0.95Mpa ；
8）反应完毕后,降温至45--50℃,出料。
低温升温速率为0.5—0.8℃/min，中温升温速率为0.2—0.3℃/min，高温升温速率为0.3—0.4℃/min。
成核剂PE 为牌号2000 与3000 的PE混合体，混合比例为1 ：0.8 ～ 1 ：1.2。
戊烷为混合戊烷，正戊烷与异戊烷的比例为6 ：4 ～ 8 ：2。
采用本技术方案，本发明的有益效果是：通过改变原辅料的种类、工艺所用原辅料配比等，使每釜产品粒子粒径更加均匀、集中，产品合格率高，泡粒弹性好，生产时发泡剂用量降低，由于具有优异的高发泡倍率、成型快、冷却时间短等加工性能，比现阶段可发性聚苯乙烯加工时节约蒸汽约30%，专门用于自动成型机的生产，生产周期比原来的原料缩短20～ 30%。
