Mortar anti-cracking waterproof powder additive and preparation method thereof
The invention relates to a mortar anti-cracking waterproof powder additive and a preparation method thereof. The additive comprises the following components in parts by mass: 30-55 parts of attapulgite powder; 60 to 75 parts of microcrystalline cellulose; 2-5 parts of sodium pyrophosphate; and 8-15 parts of a low-temperature curing accelerant, wherein the particle size of the attapulgite powder is600 to 800 meshes; the particle size of the microcrystalline cellulose is 400-600 meshes; the granularity of the sodium pyrophosphate is 50-100 meshes; and the granularity of the low-temperature curing accelerator is 600-800 meshes. The water retention capacity of the mortar can be greatly improved; moreover, the anti-aging performance is high, the anti-cracking service life is long, and the mortar can be widely applied to the market.
本发明涉及一种砂浆抗裂防水粉剂添加剂及其制备方法，添加剂的组成成分按质量份计为：凹凸棒粉30‑55份；微晶纤维素60‑75份；焦磷酸钠2‑5份；低温固化促进剂8‑15份，其中，所述凹凸棒粉的粒度为600‑800目；微晶纤维素的粒度为400‑600目；焦磷酸钠的粒度为50‑100目；低温固化促进剂的粒度粒度为600‑800目。本发明可以大幅度提高砂浆保水性能；提高砂浆抗裂、防水、抗压强度等性能，且抗老化性能强，抗裂寿命长久，有利于砂浆在市场上广泛应用。
