Nano micro-silicon anti-crack waterproof agent and preparation method thereof
The invention relates to the technical field of waterproofing, and discloses a nano micro-silicon anti-crack waterproof agent which is prepared from the following materials in parts by weight: 15 to 25 parts of zeolite powder, 20 to 35 parts of nano micro-silicon powder, 0.2 to 1.2 parts of a water reducing agent, 0.15 to 0.3 part of expanding agent master batch, 1 to 1.5 parts of a modifying agent, 1 to 1.5 parts of a water repellent, 35 to 50 parts of blast furnace micro-powder and 10 to 20 parts of microbeads. The nano micro-silicon anti-crack waterproof agent mainly comprises the zeolite powder, the nano micro-silicon powder, the microspheres, the micro powder, the auxiliaries and other non-metallic mineral products, is formed by physical mixing after roasting, modification and surface treatment, and participates in the hydration system process of cement during concrete pouring by utilizing the physicochemical properties of the materials, a continuous and uniform hydration reaction with Ca (OH) 2 and CaSO4 generated after cement hydration is carried out to generate double-expansion-source ettringite and brucite with early strength, compactness and micro-expansion, and the effects of compensating shrinkage, reducing cracks and improving strength are achieved.
本发明涉及防水技术领域，公开了一种纳米微硅抗裂防水剂，包括以下重量份材料组成：沸石粉15‑25份，纳米微硅粉20‑35份，减水剂0.2‑1.2份，膨胀剂母料0.15‑0.3份，改性剂1‑1.5份，憎水剂1‑1.5份，高炉微粉35‑50份，微珠10‑20份。该纳米微硅抗裂防水剂主要由沸石粉、纳米微硅粉、微珠、微粉及助剂等非金属矿物制品组成，经焙烧、改性、表面处理后物理混合而成，利用材料本身的理化特性，在混凝土浇筑时参与到水泥的水化体系过程中，与水泥水化后产生的Ca(OH)2及CaSO4进行连续均匀的水化反应，生成具有早强、致密、微膨胀的双膨胀源钙矾石和水镁石可起到补偿收缩减小裂缝提高强度的作用。
