Preparation method of novel boron-containing sulphoaluminate cementing material and obtained anti-radiation cementing material
The invention belongs to the field of preparation of special building materials, and particularly relates to a preparation method of a novel boron-containing sulphoaluminate cementing material and an anti-radiation cementing material obtained through the preparation method. The method comprises the following steps: grinding limestone and bauxite to below 180 meshes, drying, calculating the ratio of raw materials, introducing boron-containing chemicals, fully reacting at high temperature, rapidly cooling to normal temperature, and grinding clinker and gypsum together to 45 microns of screen residue of below 25% to obtain the novel boron-containing sulphoaluminate cementing material. According to the method, a boron-containing compound is added in a solid-phase reaction of the sulphoaluminate cement, the content of an element B is controlled in a proper range of cement clinker components, and the content of the element B is increased on the premise of not influencing the use performance of the sulphoaluminate cement, so that the novel boron-containing sulphoaluminate cement with the ray shielding capability is obtained.
本发明属于特种建材制备领域，具体涉及一种含硼新型硫铝酸盐胶凝材料制备方法及其得到防辐射胶凝材料。该方法包括如下步骤：将石灰石和铝矾土粉磨至180目以下，干燥，计算生料配比，引入含硼化学物，在高温条件下充分反应后，急速冷却降至常温，再将熟料与石膏共同研磨至45μm筛余25％以下，得到含硼新型硫铝酸盐胶凝材料。该方法在硫铝酸盐水泥固相反应中，添加含硼化合物，并控制B元素含量在水泥熟料成分合适的范围，在不影响其使用性能的前提下，提高B元素的含量，得到一种具备屏蔽射线能力的含硼新型硫铝酸盐水泥。
