Adiabatic anti-cracking vertical barrier material for composite pollutants and preparation method thereof
The invention discloses an adiabatic anti-cracking vertical barrier material for composite pollutants and a preparation method thereof. The adiabatic anti-cracking vertical barrier material is mainlyprepared from in-situ soil, sodium modified bentonite, organic modified attapulgite and a modified additive. The adiabatic anti-cracking vertical barrier material is prepared from 70 to 85 percent ofin-situ soil, 8 to 12 percent of sodium modified bentonite, 5 to 8 percent of organic modified attapulgite and 5 to 20 percent of modified additive. The main components of the modified additive comprise granulated blast furnace slag micro-powder, active magnesium oxide, basalt fiber and nano zero-valent iron in a mass ratio of 90: 10: 10: (1-90): 30: 30: 1. The adiabatic anti-cracking vertical barrier has the following characteristics that a low permeability coefficient is still kept for a high-concentration heavy metal and organic combined pollution solution; good chemical compatibility is realized; semi-rigid strength is provided, and certain toughness and cracking resistance are achieved; meanwhile, the heat-preservation and heat-insulation function is provided; and the main materials belong to green and resource recycling materials.
本发明公开了一种针对复合污染物的绝热抗开裂竖向阻隔屏障材料及制备方法。该绝热抗开裂竖向阻隔屏障材料主要由原位土、钠化改性膨润土、有机改性凹凸棒土、改性添加剂组成。该绝热抗开裂竖向阻隔屏障材料中原位土70‑85%，钠化改性膨润土8‑12%，有机改性凹凸棒土5%‑8%，改性添加剂5%‑20%。改性添加剂的主体成分包括粒化高炉矿渣微粉、活性氧化镁、玄武岩纤维、纳米零价铁，其质量占比为90:10:10:1~90:30:30:1。该绝热抗开裂竖向阻隔屏障具备如下特性：针对高浓度的重金属和有机复合污染溶液仍保持较低渗透系数；具备良好的化学兼容性；提供半刚性强度，并具备一定韧性可抗开裂；同时提供保温绝热功能；主体材料均属于绿色和资源再利用材料。
