Preparation method and application of waterproof impervious magnesium phosphate cement-based material
The invention relates to the field of magnesium phosphate cement-based materials, and particularly discloses a preparation method and application of a waterproof and impermeable magnesium phosphate cement-based material. The preparation method comprises the following steps: taking 80-100 parts by weight of magnesium phosphate cement, 5-8 parts by weight of a thickening time control agent, 10-14 parts by weight of the prepared water repellent agent, 7-10 parts by weight of modified graphene oxide and 30-40 parts by weight of active slag powder. The magnesium phosphate cement-based material is obtained by uniformly mixing the raw materials and then adding 25-32 parts by weight of mixing water. The magnesium phosphate cement is used as a main component, and the water repellent agent, the modified graphene oxide and the active slag powder are added into the magnesium phosphate cement, so that the problem that the magnesium phosphate cement coating is insufficient in water resistance and chloride ion erosion resistance is solved, and the magnesium phosphate cement coating has good crack resistance and secondary protection capability and can effectively resist erosion of water and chloride ions.
本发明涉及磷酸镁水泥基材料领域，具体公开一种防水抗渗型磷酸镁水泥基材料的制备方法及其应用。所述制备方法包括如下步骤：取磷酸镁水泥80~100重量份、调凝剂5~8重量份以及本发明制备的疏水剂10~14重量份、改性氧化石墨烯7~10重量份和活性矿渣粉30~40重量份。将上述各原料混合均匀后加入25~32重量份拌和水，即得磷酸镁水泥基材料。本发明以磷酸镁水泥为主要成分，并在其中加入所述疏水剂、改性氧化石墨烯和活性矿渣粉，不仅克服了磷酸镁水泥涂料防水、抗氯离子侵蚀能力不足的问题，而且具有良好的抗裂强度和二次防护能力，能够有效抵抗水以及氯离子的侵蚀。
