The invention provides composite isolation sand and a preparation method thereof. The composite isolation sand is of a multi-layer coating structure and comprises a mineral particle carrier, a transition layer, a functional shell layer and a surface protection layer which are sequentially arranged from inside to outside, wherein the functional shell layer comprises acrylic emulsion, Portland cement and titanium dioxide. The composite isolation sand can effectively solve the problems that natural mineral particles are poor in cohesiveness with a bonding layer and post-poured concrete, the isolation protection effect on the bonding layer is poor, and a main body reinforcing layer is prone to being rolled and damaged; and compared with artificially synthesized sand, the composite isolation sand is high in production efficiency and relatively low in production energy consumption. The composite isolation sand has excellent water resistance, weather resistance, aging resistance and ultraviolet resistance, the preparation method is simple, and generation of secondary dust in the transportation and use process is avoided.
本发明提供一种复合型隔离砂及其制备方法，所述复合型隔离砂为多层包覆结构，包括由内而外依次设置的矿物颗粒载体、过渡层、功能壳层以及表面防护层，所述功能壳层包括丙烯酸乳液、硅酸盐水泥和钛白粉。该复合型隔离砂可以有效解决天然矿物颗粒与粘结层及后浇混凝土的粘结性差，对粘结层的隔离防护效果差及易轧伤主体增强层等问题，而且相对于人工合成砂，该复合型隔离砂生产效率高、生产能耗相对较低。本发明的复合型隔离砂还具有较优的耐水性、耐候性、耐老化以及抗紫外线性能，制备方法简单，还避免了运输及使用过程中二次粉尘的产生。
