Modified EPS (Expandable Polystyrene) particles, preparation method thereof and application of modified EPS particles in ultralight ceramsite composite wallboards
The invention discloses modified EPS (Expandable Polystyrene) particles as well as a preparation method and application thereof in an ultralight ceramsite composite wallboard. The method comprises the following steps: S1, carrying out fumigation treatment on the EPS particles by using monohydric alcohol-water azeotropic steam; s2, nano metakaolin powder is added into the fumigated EPS particles for microwave treatment; s3, spraying a triethanolamine solution on the surfaces of the EPS particles; and S4, the EPS particles subjected to spraying treatment are dried, and the modified EPS particles are prepared. The EPS particles are fumigated through azeotropic steam of monohydric alcohol and water, then the nano metakaolin and the EPS particles are mixed and subjected to microwave treatment, on one hand, part of the nano metakaolin can permeate into the EPS, and the weight increasing effect is achieved; on the other hand, the microwave treatment effect can be improved by doping kaolin; the kaolin contains a large number of polar groups, so that the interface state between the EPS particle fish gel materials can be effectively improved, and the strength of the concrete doped with the modified EPS particles is relatively high.
本发明公开了一种改性EPS颗粒及其制备方法和在超轻陶粒复合墙板中的应用，方法包括：S1、利用一元醇‑水共沸蒸汽对EPS颗粒进行熏蒸处理；S2、在熏蒸处理后的EPS颗粒中加入纳米偏高岭土粉体进行微波处理；S3、在EPS颗粒表面喷洒三乙醇胺溶液；S4、将喷洒处理完的EPS颗粒烘干，即制得改性EPS颗粒。本发明利用一元醇与水的共沸蒸汽对EPS颗粒进行熏蒸，再利用纳米偏高岭土与EPS颗粒进行混合并进行微波处理，一方面，部分纳米偏高岭土能够渗入EPS内部，起到增重的作用；另一方面，高岭土的掺入能够提高微波处理的效果；还有就是高岭土含有大量的极性基团，能够有效改善EPS颗粒鱼凝胶材料之间的界面状态，使得掺入有改性EPS颗粒的混凝土的强度较高。
