抗裂和高抗渗有机硅聚合物防水砂浆及其制备方法
摘要：
本发明公开了一种抗裂和高抗渗性有机硅聚合物砂浆，该有机硅聚合物防水砂浆由以下重量份的原料制成：200～250份水泥、350～500份细砂、80～160份水、活性有机硅，所述活性有机硅含量为水泥重量的1％～5％。所述活性有机硅为RH-(OCH3)3、R-H2-(OCH3)2、RH3-OCH3、RH-(OCH2CH3)3、RH2-(OCH3)2、RH3-OCH2CH3中的一种或几种。本发明中的活性有机硅可以形成空间三维网状交联结构，能够对水泥基材料起到增强作用；即使不可避免地产生因混凝土收缩而产生的微裂缝，有机硅聚合物分子优良的憎水性也能在微裂缝和毛细孔隙表面、内壁形成憎水层，抑制水分的侵入；制备得到的防水砂浆最大抗渗压力达到4.2MPa以上。
摘要（英）：

The invention discloses cracking-resistant and high-permeability-resistant organic silicon polymer mortar. The organic silicon polymer waterproof mortar is prepared by adopting the following raw materials in parts by weight: 200 to 250 parts of cement, 350 to 500 parts of fine sand, 80 to 160 parts of water, and active organic silicon which accounts for 1 to 5 percent of the weight of the cement. The active organic silicon is one or more of RH-(OCH3)3, R-H2-(OCH3)2, RH3-OCH3, RH-(OCH2CH3)3, RH2-(OCH3)2 and RH3-OCH2CH3. The active organic silicon can form a spatial three-dimensional netted cross-linking structure which can play a role in reinforcing a cement-based material; even if micro cracks are caused by the shrinkage of the concrete, the excellent hydrophobicity of the organic silicon polymer molecules can form a hydrophobic layer in the micro cracks and on the surface and the inner wall of capillary holes so as to prevent the permeation of water; the maximum permeability-resistant pressure of the prepared waterproof mortar reaches more than 4.2MPa.
