Coral sand breathable impermeable sand
The invention belongs to the field of composite materials, and particularly relates to coral sand breathable impermeable sand and a preparation method thereof. Coral sand is generated by long-term evolution of marine microorganisms, belongs to biochemical sedimentary rock, and is completely different from desert silica sand used for preparing breathable impermeable sand in the prior art, and a precedent for successfully preparing the breathable impermeable material from the coral sand does not exist in the prior art. According to the invention, coral sand particles, a filler, a laminating agent and an adhesive are mixed according to a specific ratio, and the particle size of the coral sand particles is limited to be 50 to 200 meshes, so that the coral sand breathable impermeable sand withbreathable impermeable effects is obtained. And the filler can be selected from one or more of cement, styrene-acrylic emulsion, silicone acrylic emulsion, kaolin and rosin. The most preferable filleris a mixed filler of kaolin and rosin, and when the filler is selected, the air permeability and the water resistance of the obtained coral sand breathable impermeable sand can be optimal.
本发明属于复合材料领域，具体涉及一种珊瑚砂透气防渗砂及其制备方法。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气防渗砂的沙漠硅砂材质完全不同，现有技术中尚未有成功利用珊瑚砂制备透气防渗材料的先例。而本发明通过特定配比的珊瑚砂颗粒、填充剂、覆膜剂和粘接剂，并限定珊瑚砂颗粒为50~200目，得到了具有透气防渗效果的珊瑚砂透气防渗砂。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，所得到的珊瑚砂透气防渗砂的透气性和阻水性可达到最佳。
