为了保护环境,变废为宝,我们用合适的改性剂,对废泡沫塑料进行改性,制备常温速干、耐水时间长的水乳型防水涂料,为废泡沫塑料的利用提供了一条新途径。 1 工艺流程水乳型防水涂料的制备工艺流程如图1所示。 将废聚苯乙烯泡沫塑料用水洗净、晒干、粉碎,按一定比例加入到混合溶剂THH(二甲苯—乙酸乙酯-环已酮)中,边加边搅拌,使其完全溶解,待成粘 In order to protect the environment, turning waste into treasure, we use the right modifier to modify the waste foam to prepare a water-emulsion waterproof paint with quick-drying at room temperature and long water-resistant time, which provides a new use for waste foam way. 1 Process Water-emulsion waterproof coating preparation process shown in Figure 1. The waste polystyrene foam washed with water, dried, crushed, according to a certain percentage was added to the mixed solvent THH (xylene - ethyl acetate - cyclohexanone), while stirring, make it completely dissolved, to be stick
