High-adhesion inorganic waterproof material as well as preparation method and application thereof
The invention discloses a high-adhesion inorganic waterproof material as well as a preparation method and an application thereof. The high-adhesion inorganic waterproof material is prepared by mixing100-160 parts of magnesium phosphate cement, 240-450 parts of quartz sand, 10-25 parts of an ultrafine mineral admixture, 1-5 parts of a slow-release active material, 3-8 parts of a calcium-magnesiumexpanding agent and 25-45 parts of water. The material takes magnesium phosphate cement as a gelling system, and the binding power is superior to that of ordinary Portland cement. Due to the additionof the superfine mineral admixture, on one hand, the setting time of the magnesium phosphate cement can be properly delayed, and on the other hand, a cementing material grading effect can be achieved,so that the material compactness is improved; and a hydration product generated by hydration of the superfine mineral admixture can further compact the waterproof material. The slow-release active material can prolong the waterproof life of the waterproof material.
本发明公开一种高粘结力无机防水材料及其制备方法与应用，由磷酸镁水泥100‑160份、石英砂240‑450份、超细矿物掺合料10‑25份、缓释型活性材料1‑5份、钙镁膨胀剂3‑8份、水25‑45份混合组成。该材料以磷酸镁水泥为胶凝体系，粘结力优于普通硅酸盐水泥。超细矿物掺合料的加入一方面可以适当延缓磷酸镁水泥的凝结时间，另一方面可以起到胶凝材料级配作用，使材料密实度提高；并且超细矿物掺合料水化生成的水化产物可进一步密实防水材料。缓释型活性材料可延长该防水材料的防水年限。
