Building rubber particle modified sound insulation mortar and preparation method thereof
The invention relates to the technical field of building materials, and discloses rubber particle modified sound insulation mortar for buildings and a preparation method thereof.The rubber particle modified sound insulation mortar for the buildings is prepared from, by mass, 8-15 parts of modified rubber, 29.4-44.8 parts of cement mortar, 40-50 parts of aggregate and 8.5-15.9 parts of admixtures, waste rubber is smashed to form rubber particles, then the rubber particles are sieved, and the sieved rubber particles are dried to obtain the sound insulation mortar for the buildings. Rubber particles are soaked in a modifier to form an intermediate with a rough surface, then the intermediate is fished out, cleaned and dried, then the intermediate is soaked in emulsified asphalt for modification to prepare modified rubber, the modified rubber is fished out of the emulsified asphalt, and the modified rubber is stirred and mixed with cement mortar, aggregate and an additive to form the rubber particle modified sound insulation mortar. According to the sound insulation mortar and the preparation method thereof, the waste rubber is reused to prepare the sound insulation mortar, layering between the rubber and the mortar is avoided, the strength of the sound insulation mortar is guaranteed, and the safety of the sound insulation mortar is improved.
本发明涉及建筑材料技术领域，公开一种建筑用橡胶颗粒改性隔音砂浆及其制备方法，按质量份数计，包括以下组分：改性橡胶8～15份、水泥砂浆29.4～44.8份、骨料40～50份以及外加剂8.5～15.9份，废旧橡胶粉碎形成橡胶颗粒后过筛，将橡胶颗粒浸泡于改性剂中形成表面粗糙的中间体，再将中间体捞出清洗且干燥后，浸泡于乳化沥青中改性制得改性橡胶，将改性橡胶从乳化沥青中捞出，与水泥砂浆、骨料和外加剂搅拌混合形成橡胶颗粒改性隔音砂浆，该隔音砂浆及其制备方法将废旧橡胶重新利用制备成隔音砂浆的同时，避免橡胶和砂浆之间的分层，保证隔音砂浆的强度，提升隔音砂浆的安全性。
