The invention discloses anti-crack mortar and a preparation method therefor and relates to the technical field of energy-saving anti-cracking materials for exterior walls of buildings. The anti-crack mortar, i.e., finished product is prepared through stirring cement, pulverized coal ash, quartz sand, hydroxypropyl methylcellulose, special anti-cracking glue powder, wood fibers and pp short fibers by a mixing host, and then, carrying out bagged packaging. The anti-crack mortar is high in safety, long in service life, low in cost, good in strength, small in coefficient of thermal conductivity and good in anti-cracking effect. 种抗裂砂浆及其制备方法，涉及种用于建筑外墙体节能抗裂材料技术领域。是将水泥、粉煤灰、石英砂、羟丙基甲基纤维素、抗裂专用胶粉、木质纤维、pp短纤维进行混合主机搅拌后分袋包装制成成品。本发明安全性高、使用寿命长、成本低、强度好、导热系数低、抗裂效果好。
