Cementing material and preparation method thereof
The invention discloses a cementitious material and a preparation method thereof, the cementitious material comprises the following components: magnesium oxide, aluminum oxide and nanometer ferroferric oxide, the mass fraction ratio of magnesium oxide to aluminum oxide is 1: 1, and the molar percentage of nanometer ferroferric oxide is 2-20%. After the gel material is hydrated, a magnesium oxide and aluminum oxide coating film is more compact, the contact between external gas and a metal component is reduced, meanwhile, ferroferric oxide nanoparticles are gathered and coated on the metal component, and the metal component is further prevented from being corroded by chlorine; according to the preparation method of the gel material, brucite waste fine ore is mainly utilized, mine resource reutilization is achieved, the production cost is low, and meanwhile dust secondary pollution caused by stacking of natural brucite fine ore waste everywhere is avoided.
本发明公开了一种胶凝材料及其制备方法,一种胶凝材料包括以下组分:氧化镁、氧化铝、纳米四氧化三铁,氧化镁与氧化铝的质量分数百分比为1:1,纳米四氧化三铁的摩尔百分比为2%~20%。本发明凝胶材料水合后氧化镁氧化铝包覆膜更加致密,减少外界气体与金属部件接触,同时四氧化三铁纳米微粒聚集包覆在金属构件上,进一步避免金属部件遭到氯蚀;本发明凝胶材料的制备方法主要利用了水镁石废弃粉矿,对矿山资源化再利用,生产成本低,同时避免了天然水镁石粉矿废物随处堆放引起的粉尘二次污染。
