Lightweight sound insulation floor slurry containing polyurethane particles, preparation method thereof and lightweight sound insulation floor
The invention provides lightweight sound insulation floor slurry containing polyurethane particles, a preparation method thereof and a lightweight sound insulation floor. The lightweight sound insulation floor slurry containing the polyurethane particles is prepared from the following components in parts by weight: 30 to 45 parts of polyurethane particles, 9 to 20 parts of a modifier, 250 to 450 parts of a cementing material, 0 to 1000 parts of fine aggregate, 3 to 15 parts of a water reducing agent, 75 to 200 parts of water, 0.5 to 5 parts of a foaming agent and 4 to 10 parts of an auxiliary agent. The prepared lightweight sound insulation terrace containing the polyurethane particles has the volume weight of 300-1500 kg/m < 3 >, the heat conductivity coefficient of 0.06-0.3 W/m * k and the compressive strength of 1-15 MPa, has good heat preservation and sound insulation effects and is light in weight, the polyurethane foam particles can be recycled, and waste is turned into wealth.
本发明提供了一种含有聚氨酯颗粒的轻质隔音地坪浆料及其制备方法以及轻质隔音地坪。按重量份计，含有聚氨酯颗粒的轻质隔音地坪浆料包括以下组分：30‑45份聚氨酯颗粒、改性剂9‑20份、胶凝材料250‑450份、细集料0‑1000份、减水剂3‑15份、水75‑200份、发泡剂0.5‑5份、助剂4‑10份。制备得到的含有聚氨酯颗粒的轻质隔音地坪的容重为300‑1500kg/m3，导热系数0.06‑0.3W/m*k，抗压强度1‑15MPa,具有良好的保温隔音效果以及重量轻，并且能够对聚氨酯泡沫颗粒实现回收利用，变废为宝。
