The present invention relates to the technical field of building materials, and discloses a building wall sound insulation mortar production method, which uses cement, fly ash, quartz sand, core-shell hollow glass beads, modified fibers, dispersible latex powder, a polyacrylic acid water reducing agent, methyl hydroxypropyl cellulose ether and water as raw materials, and the raw materials are stirred and mixed to form the sound insulation mortar, by utilizing the sound absorption effect and filling effect of the shell-core hollow glass beads, the prepared mortar can have a good sound insulation effect, internal stress generated by drying shrinkage of the mortar is weakened, the modified fibers can form a compact net-shaped structure with basalt fibers as a core framework in the mortar, all the components in the mortar are bonded more tightly, and the sound insulation performance of the mortar is improved. The shrinkage rate of the mortar during forming is reduced, and the strength and the crack resistance of the mortar are further improved.
本发明涉及建筑材料技术领域，公开了一种建筑墙体隔音砂浆的制造方法，以水泥、粉煤灰、石英砂、壳核空心玻璃微珠、改性纤维、可分散乳胶粉、聚丙烯酸减水剂、甲基羟丙基纤维素醚和水为原料，经搅拌混合即可形成隔音砂浆，利用壳核空心玻璃微珠的吸音作用和填充作用，可使制备的砂浆具有良好的隔音效果，并减弱砂浆干燥收缩产生的内应力，改性纤维可在砂浆中形成以玄武岩纤维为核心骨架的致密网状结构，使砂浆中各成分的粘结更加紧密，降低砂浆成型时的收缩率，进一步提高砂浆的强度和抗裂性能。
