Immersion-resistant isolation sand, non-asphalt-based pre-paved waterproof coiled material and preparation method thereof
The invention relates to a soaking-resistant isolation sand, a non-asphalt-based pre-paved waterproof roll and a preparation method thereof. The soaking-resistant isolation sand is composed of a core layer, a middle layer and an outer layer, the core layer is prepared from the following components: ordinary Portland cement, fly ash, an additive and water; the middle layer comprises a first agent layer, a second agent layer, a first agent layer and a second agent layer which are sequentially stacked, and the first agent layer and the second agent layer are prepared from a first agent solution and a second agent solution respectively; the agent A solution is prepared from the following components: sodium silicate, potassium silicate, a surfactant A, a reaction retarder, a reducing agent, a reaction accelerator, a surface enhancer and water; the solution B is prepared from the following components: calcium hydroxide, sodium hydroxide, a surfactant B and water; and the outer layer is prepared from a silane coupling agent alcoholic solution. The waterproof coiled material overcomes the defect that a hot-melt pressure-sensitive adhesive layer of an existing waterproof coiled material is stripped from a base material when meeting water, the waterproof coiled material is prepared by sequentially wrapping the core layer, the middle layer and the outer layer with the water-resistant isolation sand, and the waterproof coiled material is extremely good in waterproof performance.
本发明涉及一种耐浸水隔离砂、非沥青基预铺防水卷材及其制备方法，由芯层、中间层以及外层构成；芯层由以下组分制备而成：普通硅酸盐水泥、粉煤灰、外加剂、水；中间层包括依次叠设的甲剂层、乙剂层、甲剂层与乙剂层，甲剂层与乙剂层分别由甲剂溶液和乙剂溶液制备而成；甲剂溶液由以下组分制备而成：硅酸钠、硅酸钾、表面活性剂A、反应延迟剂、还原剂、反应促进剂、表面强化剂、水；乙剂溶液由以下组分制备而成：氢氧化钙、氢氧化钠、表面活性剂B、水；外层由硅烷偶联剂醇溶液制备而成。该发明克服了现有防水卷材遇水热熔压敏胶层与基材剥离的缺点，由芯层、中间层以及外层依次包裹制成耐浸水隔离砂，并制成防水卷材，防水性能极佳。
