Magnesium slag-based foaming material and preparation method thereof
The invention belongs to the technical field of foaming materials, and particularly relates to a magnesium slag-based foaming material and a preparation method thereof. The magnesium slag-based foaming material is prepared from the following components in percentage by mass: 56% of magnesium slag, 1.7% of corncob, 27% of water glass, 4.4% of sodium hydroxide and 10.9% of tap water. According to the magnesium slag-based foaming material, the corncobs are subjected to thermal decomposition at a high temperature to form pores, so that the foaming performance of the magnesium slag-based foaming material is effectively improved; and the sodium silicate and the sodium hydroxide are added, so that the activity of the magnesium slag can be excited, the compressive strength of the magnesium slag-based foaming material is enhanced, and the contradictory problem that the porosity and the strength are not compatible is solved. The magnesium slag-based foaming material can adsorb metal ions in water, and is beneficial to promoting solid waste resource utilization and development of wastewater treatment functional materials.
本发明属于发泡材料技术领域，具体涉及一种镁渣基发泡材料及其制备方法。本发明镁渣基发泡材料由按质量分数计的下列组分制成：镁渣56％，玉米芯1.7％，水玻璃27％，氢氧化钠4.4％，自来水10.9％。本发明镁渣基发泡材料利用玉米芯在高温下热分解造孔，有效提高了镁渣基发泡材料的发泡性能；加入水玻璃和氢氧化钠则可以激发镁渣的活性，增强了镁渣基发泡材料的抗压强度，克服了气孔率和强度不能兼容的矛盾问题。本发明镁渣基发泡材料能吸附水中金属离子，有利于推进固废资源化利用和废水处理功能材料的发展。
