Coated excitant for alkali slag cement and preparation method of coated excitant
The invention belongs to the field of building materials, and particularly relates to a coated excitant for alkali slag cement and a preparation method of the coated excitant. The coated excitant is composed of a core material and a wall material to form an inclusion, the core material is formed by an alkali activator, and the wall material is formed by hydrophobic polymer powder. The coated excitant is prepared in a coating mode and mixed with slag, the setting time of the alkali slag cement can be effectively changed, the polymer film plays a role in coating in the early stage to achieve thepurpose of delayed release of the excitant, and the polymer film is dispersed in the alkali slag cement along with hydration reaction in the later stage, due to the good bonding effect, the compression-bending ratio can be effectively reduced, and the mechanical property and durability of the alkali slag cement are improved.
本发明属于建筑材料领域，具体涉及一种用于碱矿渣水泥的包裹型激发剂及其制备方法。该包裹型激发剂由芯材和壁材组成，形成包裹体，所述芯材由碱激发剂形成，所述壁材由憎水性聚合物粉末形成。本发明采用包裹的方式制备出包裹型激发剂，并将该包裹型激发剂与矿渣混合，可以有效改变碱矿渣水泥的凝结时间，聚合物薄膜前期起到包裹作用来达到延迟释放激发剂的目的，后期随着水化反应，聚合物薄膜分散在碱矿渣水泥中，其较好的粘结作用可以有效降低压折比，改善碱矿渣水泥的力学性能和耐久性。
