Coral sand permeable material and preparation method thereof
The invention belongs to the field of composite materials, and particularly relates to a coral sand permeable material and a preparation method thereof. Coral sand is generated by long-term evolutionof marine microorganisms, belongs to biochemical sedimentary rock, is completely different from desert silica sand used for preparing permeable ecological sand in the prior art in material, and has the characteristics of poor sphericity, high angularity, large porosity and the like; and the coral sand building block cannot be prepared by adopting the conventional technical means to achieve the ideal performance effect. The coral sand particles, the filler, the laminating agent, the additive and the adhesive in a specific ratio are used, and the particle size of the coral sand particles is limited to be 50-200 meshes so that the water-permeable and salt mist-resistant coral sand building block is obtained. The filler can be selected from one or more of cement, styrene-acrylic emulsion, silicone acrylic emulsion, kaolin and rosin. The most preferable filling agent is a mixed filling agent of kaolin and rosin, and when the filling agent is selected, the compression resistance of the obtained coral sand permeable material can be optimal.
本发明属于复合材料领域，具体涉及一种珊瑚砂透水材料及其制备方法。珊瑚砂是由海洋微生物经过漫长年代进化而生成的，属生物化学沉积岩，其与现有技术中用来制备透水型生态砂的沙漠硅砂材质完全不同，具有圆球度差、棱角度高、孔隙率大等特性，无法采用常规技术手段来制备珊瑚砂砌块而达到理想的性能效果。而本发明通过特定配比的珊瑚砂颗粒、填充剂、覆膜剂、添加剂和粘接剂，并限定珊瑚砂颗粒为50~200目，得到了既透水又抗盐雾的珊瑚砂砌块。所述填充剂可选水泥、苯丙乳液、硅丙乳液、高岭土和松香中的一种或多种。其中，最优选的填充剂为高岭土和松香的混合填充剂，当选用此填充剂时，所得到的珊瑚砂透水材料的抗压性能可达到最佳。
