Negative carbon type composite material and preparation method thereof
The invention discloses a negative carbon type composite material, which is prepared from the following ingredients in parts by weight: 50 to 130 parts of vaterite type calcium carbonate, 0.2 to 2.5 parts of magnesium salt, 1.0 to 4.5 parts of strontium salt, 10 to 70 parts of water and 0.03 to 4 parts of organic filling materials. The organic filling material is triethanolamine; magnesium salt and strontium salt are dissolved in water, the organic filling material is added and stirred and dispersed, and a homogeneous mixed solution is obtained; stirring and mixing vaterite type calcium carbonate and the homogeneous mixed solution until a slurry state appears; pouring the slurry into a mold for curing and forming; the organic filling material adopted by the invention not only can be compatible with other components in the cementing material, but also can form a stable network structure in the drying process, so that pores are effectively reduced, the overall compactness and mechanical strength of the material are improved, and due to the improvement, the material has excellent performance in engineering application for bearing heavy load or requiring high durability.
本发明公开了一种负碳型复合材料，组成按重量份数计如下：球霰石型碳酸钙50～130份，镁盐0.2～2.5份，锶盐1.0～4.5份，水10～70份，有机填充材料0.03～4份；所述有机填充材料为三乙醇胺；将镁盐和锶盐溶于水中，加入有机填充材料搅拌分散，获得均质混合溶液；将球霰石型碳酸钙与上述均质混合溶液搅拌混合至出现浆体状态；将上述浆体浇筑至模具中养护成型；本发明采用的有机填充材料不仅能够与胶凝材料中的其他组分相容，而且能够在干燥过程中形成稳定的网络结构，有效减少孔隙，提高材料的整体密实度和力学强度，这种改进使得材料在承受重载或要求高耐久性的工程应用中表现出色。
