Cement-based composite material blanket based on sandwich mesh cloth and preparation method of blanket
The invention discloses a cement-based composite material blanket based on sandwich screen cloth and a preparation method of the blanket. The cement-based composite material blanket comprises the sandwich screen cloth, the sandwich screen cloth comprises a mesh surface layer evenly provided with meshes, a plain cloth bottom layer and connecting monofilaments for connecting the mesh surface layer and the plain cloth bottom layer, the sandwich screen cloth is filled with a curable dry powder material, and the top surface and the two sides of the sandwich screen cloth are coated with waterproof polymer cement layers. The dry powder material is formed by mixing cement and sand according to the mass ratio of 1:1, the cement comprises 20% of sulphoaluminate cement and 80% of Portland cement, andthe sand is dry river sand and/or sea sand. The meshes can be firmly fixed after the polymer cement is condensed, so that the cement material is difficult to move or leak in a mesh cloth body. The polymer cement material has good flexibility and waterproof effect, has good interface property with a cement material matrix and is bonded, so that the polymer cement material is solidified into a firmwhole, and the anti-seepage effect of the material blanket is guaranteed. The preparation method is simple, reliable and convenient to install and construct.
本发明公开了基于三明治网布的水泥基复合材料毯及其制备方法，包括三明治网布，三明治网布包括均布有网孔的网孔面层、平布底层和连接两者的连接单丝组成，所述的三明治网布内部填充有可固化的干粉材料，顶面和两侧涂设防水聚合物水泥层；所述的干粉材料由水泥和沙子按1:1质量比混合而成，其中的水泥包括20％的硫铝酸盐水泥和80％的硅酸盐水泥，沙子为干燥的河沙和/或海沙。聚合物水泥凝结后会牢牢固定网孔，使水泥材料在网布体内难以移动或者漏失；聚合物水泥材料具有很好的柔韧性和防水效果，并且与水泥材料基体存在良好的界面性而粘接，从而凝固成为牢固整体，保证了材料毯的防渗效果。本制备方法简单可靠，安装、施工方便。
