Sound insulation mortar with excellent tensile compressive properties and preparation method thereof
The invention discloses sound insulation mortar with excellent tensile compressive properties. The sound insulation mortar comprises: 60-80 parts of Portland cement; 20-30 parts of fine sand; 15-20 parts of ash calcium powder; 15-20 parts of vitrified microbeads; 5-15 parts of activated rubber powder; 8-12 parts of redispersible latex powder; 8-15 parts of clay; 8-12 parts of bentonite; 3-5 partsof cellulose ether; 3-5 parts of damping filler; and 5-10 parts of porous fibers. Porous fiber and activated rubber powder are reacted and combined, and the rubber powder is distributed on the surfaceof the porous fiber. Rubber is arranged on the surface of the porous fiber, the rubber further improves the crack resistance and tensile properties of the fiber, the rubber itself can also obviouslyimprove the tensile crack resistance of the mortar, and the combination of the porous fiber and the rubber can obviously improve the overall tensile compressive properties and crack resistance of themortar. According to the invention, a porous density structure of the porous fiber and vitrified microbeads is utilized to achieve a better sound volume adsorption effect, and the damping filler is cooperated to achieve a good sound absorption and sound insulation effect.
本发明公开了一种拉伸抗压性能优良的隔音砂浆，包括：硅酸盐水泥60‑80份；细砂20‑30份；灰钙粉15‑20份；玻化微珠15‑20份；活化橡胶粉5‑15份；可再分散乳胶粉8‑12份；黏土8‑15份、膨润土8‑12份；纤维素醚3‑5份；阻尼填料3‑5份；多孔纤维5‑10份。本发明将多孔纤维与活化的橡胶粉末反应结合，橡胶粉末分布在多孔纤维表面。多孔纤维表面带有橡胶，橡胶进一步提升了纤维本身的抗裂和拉伸性能，橡胶本身也能明显提高砂浆的拉伸抗裂性能，多孔纤维和橡胶的结合，能够显著提高其整体对砂浆的拉伸抗压以及抗裂强度的提升效果。本发明利用多孔纤维、玻化微珠的多孔疏密结构，起到更好的音量吸附效果，配合阻尼填料，起到良好的吸音隔音效果。
