Composite isolation protective sand and preparation method
The invention discloses composite isolation protective sand which is of a multi-layer coating structure and sequentially comprises aggregate, a transition layer, a functional shell layer and a surface protective layer from inside to outside. The transition layer, the functional shell layer and the surface protective layer are arranged on the outer surfaces of the mineral particles, so that the problems that the natural mineral particles are poor in cohesiveness with a bonding layer and post-pouring concrete, the isolation protection effect on the bonding layer is poor, the hardness is high, edges and corners are clear, a main body reinforcing layer is prone to being rolled and damaged and the like can be effectively solved. The composite isolation protective sand is high in production efficiency and relatively low in production energy consumption, meanwhile, the composite isolation protective sand is endowed with excellent water resistance, weather resistance, aging resistance and ultraviolet resistance, and secondary dust is prevented from being generated in the transportation and use process.
本发明公开了一种复合型隔离防护砂，其为多层包覆结构，由内而外依次为骨料、过渡层、功能壳层以及表面防护层。本发明在矿物颗粒外表面设置过渡层、功能壳层以及表面防护层，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硬度大、棱角分明易轧伤主体增强层等问题，而且相对于人工合成砂，本发明的复合型隔离防护砂生产效率高、生产能耗相对较低，同时还赋予其较优的耐水性、耐候性、耐老化以及抗紫外线性能，还避免了运输及使用过程中二次粉尘的产生。
