Composite cement-based material capable of buffering, absorbing energy and reducing vibration and preparation method thereof
The invention discloses a composite cement-based material capable of buffering, absorbing energy and reducing vibration and a preparation method of the composite cement-based material. The cement-based material is prepared by mixing the following raw materials in parts by mass: 200-450 parts of Portland cement, 10-50 parts of waterborne polyurethane emulsion, 20-150 parts of foamed aluminum, 5-8 parts of mixed organic polymerized rubber and 80-180 parts of water. The cement-based material is simple in preparation process, raw materials are easy to obtain, foamed aluminum serving as energy absorption metal is widely applied, the foamed aluminum serving as an energy absorption interlayer is compounded with the cement-based material to effectively improve the energy absorption and vibration reduction performance of the cement-based material, and the waterborne polyurethane emulsion serving as a reinforcing agent can improve the working performance of the cement-based material and improvethe durability and safety of the cement-based material.
本发明公开了一种可缓冲吸能减振复合型水泥基材料及其制备方法，所述水泥基材料是由以下质量百分比的原料混合组成：硅酸盐水泥200～450份，水性聚氨酯乳液10～50份，泡沫铝20～150份，混合有机聚合橡胶5～8份，水80‑180份。该水泥基材料制备工艺简单、原料易得，泡沫铝作为吸能金属应用广泛，将其作为吸能夹层与水泥基材料复合可有效提高水泥基材料的吸能减振性能，水性聚氨酯乳液作为补强剂，可以提高水泥基材料工作性能，提高其耐久性和安全性。
