Rigid waterproof isolation sand special for pre-laid waterproof coiled material and preparation method of rigid waterproof isolation sand
The invention relates to the technical field of waterproof coiled materials, in particular to rigid waterproof isolation sand special for a pre-laid waterproof coiled material and a preparation method of the rigid waterproof isolation sand. The rigid waterproof isolation sand comprises a core material and a coating layer arranged outside the core material; the core material comprises, by weight, 85 parts of the core material; and the coating layer is prepared from the following components in parts by weight: 20 to 30 parts of cement, 50 to 60 parts of cement-based permeable crystallization master batch, 20 to 30 parts of quartz sand, 10 to 13 parts of water-soluble emulsion, 3 to 5 parts of coupling agent and 2 to 4 parts of ultraviolet light absorber. The defect that traditional isolation sand cannot resist water is overcome, the peel strength of the traditional isolation sand and post-poured concrete is low, and the waterproof effect of the pre-laid waterproof coiled material is affected. The rigid waterproof type isolation sand provided by the invention has the advantages of high peel strength with post-poured concrete, strong base deformation adaptability and double waterproof functions. Meanwhile, the raw materials are easy to obtain and fewer in the types, the preparation process is simple, construction is convenient, the comprehensive cost is low, and therigid waterproof isolation sand is suitable for large-scale industrial production and wide use.
本发明涉及防水卷材技术领域，尤其涉及一种预铺防水卷材专用刚性防水型隔离砂及其制备方法，包括芯材及设于芯材外部的包覆层，所述芯材包括如下重量比的成分：芯材85份，所述包覆层包括如下重量比的成分：水泥20～30份、水泥基渗透结晶母料50～60份、石英砂：20～30份，水溶性乳液10～13份、偶联剂3～5份、紫外线吸收剂：2～4份。本发明克服了传统的隔离砂自身不能防水的缺陷，与后浇混凝土剥离强度低，影响预铺防水卷材的防水效果。采用本发明提供的具有刚性防水型的隔离砂具有与后浇混凝土的剥离强度高、适应基层变形能力强、具有双道防水。同时原材料易得，所用到的原料种类少，制备工艺简便，施工方便，综合成本低廉，适用于大规模工业生产和广泛使用。
