The invention relates to high-strength anti-crack mortar and a preparation method thereof, and belongs to the technical field of building material preparation. The preparation method comprises the following steps: by taking bentonite as a raw material, crushing the bentonite, mixing the crushed bentonite with castor oil, performing high-temperature and high-humidity rancidity treatment to obtain arancidity product, mixing and open-milling the rancidity product, natural rubber, butadiene rubber and alumina sol, mixing and extruding the open-milled product and rock wool fibers to obtain a self-made anti-cracking filler; taking glass beads as raw materials, soaking the glass beads in ammonia water and then activating, and finally,blending the self-made anti-cracking filler, the activated glass beads and other auxiliary materials to prepare the high-strength anti-crack mortar which is good in compressive strength and breaking strength, excellent in tensile bonding strength and not prone to cracking. Wide application prospects are realized.
本发明涉及一种高强度抗裂砂浆及其制备方法，属于建筑材料制备技术领域。本发明首先以膨润土为原料，将其粉碎后和蓖麻油混合并高温高湿酸败处理，得到酸败产物，再将酸败产物和天然橡胶和顺丁橡胶以及氧化铝溶胶混合开炼，接着将开炼产物和岩棉纤维混合后挤出，得到自制抗裂填料，随后本发明以玻璃化微珠为原料，将其用氨水浸泡后活化，最终将自制抗裂填料和活化玻璃微珠以及其他辅料共混，制得高强度抗裂砂浆，本发明制备的抗裂砂浆，抗压强度和抗折强度良好，拉伸粘结强度优良，不容易产生裂纹，有广阔的应用前景。
