摘要： The present invention relates to a new water-disintegrable environmentally friendly macromolecular material formed by blending fine particles of water absorbing resins into polystyrene material and the like, said material will disintegrate into powder in a certain rate or lose its intensity when meets water. The present invention also relates to two kinds of methods for preparing the material. The first method is the blend polymerization method by adding fine particles of water absorbing resins which have particle sizes of up to 5 µ m and initiators into styrene monomers and the like followed by polymerization. The second method is the reverse phase-two phase polymerization method by agitating monomers which will become water absorbing polymer after polymerization, such ais oil-soluble monomer like styrene, sodium acrylate, and methylene bisacrylamide, with water, initiators and W/O type emulsifiers, forming W/O type emulsion, then carrying out polymerization. The material of the present invention has the advantage of simple preparing method, low, cost, water disintegrating rate in control and etc, it can be in place of disposable packing materials such as disposable lunch boxes, foamed polystyrene which pollutes environment heavily and is hard to be recycled at present, etc.
摘要翻译：本发明涉及一种新型水解性环保型高分子材料，它是通过将吸水树脂微粒与聚苯乙烯材料等混合而成，该材料在遇水时会以一定的速度崩解成粉末或失去其强度。本发明还涉及两种制备该材料的方法。第一种方法是混合聚合方法，通过向苯乙烯单体等中加入颗粒尺寸高达5μm的吸水树脂的细颗粒和引发剂，然后聚合。第二种方法是反相 - 二相聚合方法，通过搅拌聚合后成为吸水聚合物的单体，例如苯乙烯，丙烯酸钠和亚甲基双丙烯酰胺等油溶性单体与水，引发剂和W / O型乳化剂，形成W / O型乳液，然后进行聚合。本发明的材料制备方法简单，成本低，控制水分解速度快等优点，可代替一次性饭盒，泡沫聚苯乙烯等一次性包装材料，对环境造成严重污染，且硬度较高目前回收利用等。
