摘　　要：利用粉煤灰、硅酸钠等研制了双组分菱镁材料改性剂,用于菱镁材料的改性,大大提高了菱镁材料的耐水性、强度和抗返卤性能。并利用改性好的菱镁材料以及玻化微珠制备菱镁基无机保温材料,用于建筑物的保温,拓展了菱镁材料的应用领域。Coal ash and sodium silicate were used to prepare two-component modified magnesite. Through modification, the water resistance, strength and anti - halogen properties of magnesite were improved greatly .The preparation of based inorganic thermal insulation materials from magnesite materials and glass bubbles has expanded the application field of magnesite materials.
