Abstract

本发明是由废聚苯乙烯泡沫塑料为主要原料制备的一种不干胶。这种胶适合于用来将纸张一类物品(如商标、标签)粘贴在玻璃、金属、墙壁等物体的表面。因本发明利用废弃的聚苯乙烯泡沫塑料作原料,因此,不仅成本低廉,而且消除了公害。此外,这种胶粘贴效果好,能重复使用。耐酸、耐碱、耐冻。通过调节配制材料的重量百分比,可以调节本不干胶的粘度及干燥速度。

Description

本发明涉及一种不干胶及其制法。
现有不干胶主要用天然胶制成,因此成本较高。
本发明的目的是提供一种用铁路客车上扔掉的快餐饭盒、包装仪器、设备用的泡沫塑料块、以及生产泡沫塑料产品后的下角料等废弃物制造不干胶。用废弃物制作不干胶,不仅成本低廉,而且消除了公害。
本发明采用以下材料,并按下述重量百分比进行配制:
废聚苯乙烯泡沫塑料:20~40%
有机溶剂:30~45%
增塑剂:25~35%
辅料:1~3%
有机溶剂为江苏吴江北库化工二厂及一分厂生产创的新一号代二甲苯或无苯毒稀释剂。即:①无苯稀释剂(辽宁省本溪石油化学厂生产),②无苯低毒涂料稀释剂(铁道部科学研究院研究生部生产)。增塑剂为邻苯二甲酸二丁酯。辅料为醋酸乙酯或香精。
本发明的制作过程:
首先将聚苯乙烯泡沫塑料废弃物进行清洗、晾干,并将清洁、干燥后重量百分比为:20~40%的废聚苯乙烯泡沫塑料压进30~45%的有机溶剂中,直到完全溶化为止。然后加入25~35%的增塑剂,搅拌均匀。或先把增塑剂按上述百分比加入有机溶剂中,最后放入1~3%的香精。
实施例:
按重量百分比将30%的废聚苯乙烯泡沫塑料压进43%的创新一号(代二甲苯)中,直到废聚苯乙烯泡沫塑料完全溶于其中为止。然后,加入25%的邻苯二甲酸二丁酯,最后放进2%的香精。
本发明与现有技术相比,具有以下优点:
1、废物利用,清除公害;
2、成本低廉;
3、粘贴效果好,且能重复粘贴;
4、耐酸、耐碱、耐冻;
5、通过调节配制材料的重量百分比,可以改变本不干胶的速度。
