Description

一种高性能抗水渗入材料的制备方法
技术领域
本发明属于防水渗入材料制备领域，涉及一种高性能防水渗入材料的制备方法，用于堤坝、浴池、水池、地下室、楼房顶部等防水领域，也可用于改良不保水的贫瘠土壤。
背景技术
防水渗入材料是一种非常重要的材料，在屋顶、公路、机场、水库堤坝、浴室、厨房、隧道、游泳池等领域发挥着重要作用。防水渗入材料质量的好坏直接关系到工程建设质量。随着社会生活条件的不断改善，人们对防水渗入材料要求越来越高。随着科技的快速发展，防水材料经历了沥青、聚氨酯树脂、聚丙烯酸和聚丙烯酰胺聚合物、无机渗透盐等的发展过程。其中，沥青和聚氨酯树脂型防水材料因污染严重，且含有毒性，已被国家明令禁止；丙烯酸和丙烯酰胺聚合物类防水材料持久性差，容易老化，寿命短，另外，一旦防水膜层被破坏，就马上发生渗漏现象。专利CN201810116545.7公布了一种用于房屋建筑的防水材料及其制备方法，该专利采用环氧树脂、聚氨树脂、石英砂、沥青、二氧化锆等原料，虽然具有一定的防水效果，但是使用寿命不长。专利CN1800291公布了一种堵漏防水材料，该堵漏防水材料由重量百分比为硅酸盐水泥24-60％、高铝熟料20-63％、十二水硫酸铝钾0-10％、二水石膏1-5％、聚丙烯酸钠0-1％、膨润土2-10％、乳胶粉0-2％、石英砂10-20％组成，虽然在短时间内具有某减缓水的渗入的功效，但是长时间使用后，水仍然能够渗入。专利CN108359292A公开一种水泥基防水材料的制备方法，该方材料以水、乙醇、硅烷偶联剂、钠基膨润土研磨和氢氧化钠等为原料，不仅工艺复杂，而且防水效果不理想。
发明内容
本发明针对现有技术的缺点，提供了一种高性能的防水渗入材料的制备方法，该材料由乙基硅酸钠、聚丙烯酸盐-硅藻土材料等构成，具有很好的防水渗入效果。将其和水按一定的比例混合后，填充漏缝或则铺在需要防水物体的表面上即可。
具体技术方案为：
一种高性能抗水渗入材料的制备方法，将该抗水渗入材料中各组分按以下重量比混合而成：
Figure BDA0001867781980000021
所述的添加剂为按照质量比1：3：6配置的亚甲基双丙烯酰胺、过硫酸钠、海藻酸钠混合物。
进一步地，上述的聚丙烯酸盐-硅藻土是指硅藻土的重量百分比为60-90％，其余为聚丙烯酸盐；所述聚丙烯酸盐为聚丙烯酸钠、聚丙烯酸钾或者聚丙烯酸氨中的一种或两种以上。
进一步地，上述的沙土的粒度为100-150目。
进一步地，上述的粗沙的粒度为10-50目。
进一步地，上述的氧化钙的粒度为100目。
进一步地，上述的水泥为普通的硅酸盐水泥或者铝酸盐水泥。
上述方法制得的高性能抗水渗入材料的应用，施工时，按照高性能抗水渗入材料与水的质量比为2:1混合，并搅拌均匀后填充裂缝或者铺涂到屋顶等需要防水物体的表面上即可，铺涂厚度2-8cm。
本发明的有益效果为：该方法制得的防水渗入材料容易吸水，吸水后快速膨胀填补裂缝，而且能够在需要防水的材料表面和内部同时形成疏水层，阻止水的渗入，起到双重密封防水的作用，因此能够有效地可防止水的渗入或者渗透。可用于堤坝、浴池、水池、地下室、楼房顶部等防水渗入领域，具有抗水渗入能力高，防水有效时间长、无毒无害和使用方便的特点。
