Sound-absorbing and shock-absorbing building material and preparation method thereof
The invention belongs to the field of buildings, and particularly relates to a sound-absorbing and shock-absorbing building material and a preparation method thereof. The sound-absorbing and shock-absorbing building material comprises the following raw materials: cement, sepiolite, nano silicon dioxide, sodium methyl silicate, polystyrene, high-substituted hydroxy propyl cellulose, acetone and water. According to the invention, a porous system is formed by utilizing the characteristics of unique physical and chemical properties, high specific surface area and porosity of sepiolite fibers; and the nano silicon dioxide is well doped under the condition that the sepiolite fibers are softened, and hydroxyl on the surface of the nano silicon dioxide and Si-OH on the surfaces of the sepiolite fibers are utilized to form a polymerization effect, so that internal curing is achieved, and the firmness is improved.
本发明属于建筑领域，具体涉及一种吸音减震建筑材料及其制备方法，包括如下原料：水泥、海泡石、纳米二氧化硅、甲基硅酸钠、聚苯乙烯、高取代羟丙基纤维素、丙酮和水。本发明利用海泡石纤维的具有独特的理化性能，它的比表面积高和孔隙率的特点，形成多孔体系；纳米二氧化硅在海泡石纤维软化情况下形成良好的掺杂，并利用纳米二氧化硅表现的羟基和海泡石纤维表面Si‑OH形成聚合效果，达到内固化，提升自身牢固强度。
