摘　　要：研究了几种国内外常用的有机硅防水剂产品的性能及应用效果,考察了不同稀释比例对有机硅防水剂吸水率比、渗透性以及基材表面疏水效果、变色情况等的影响。结果表明,有机硅防水剂具有较好的防水效果及表面疏水效应,在合适的稀释比例下处理基材,不会导致基材表面变色;总体而言,硅烷/硅氧烷类有机硅防水剂的防水效果与疏水效果均好于烷基硅酸盐类有机硅防水剂。The performance and application effects of several commonly used silicone waterproofing agents at home and abroad are studied in this article,and the effects of different dilution ratios on the water absorption ratio,permeability,substrate surface hydrophobicity,and discoloration of silicone waterproofing agents are investigated.The results show that the silicone waterproofing agent has good waterproofing effect and surface hydrophobic effect,and the substrate surface will not change color when treated with appropriate dilution ratio;overall,the waterproofing and hydrophobic effects of silane/siloxane based silicone waterproofing agents are better than those of alkyl silicate based silicone waterproofing agents.
