摘要
通过筛选实验确定了合成遇水膨胀聚氨酯防水弹性体用的亲水性多元醇的种类、比例以及相关多元醇的相对分子质量。又通过对比实验选定了填料、偶联剂的种类和比例。研制出的防水弹性体综合性能优于国内外同行的市售产品。
The types and ratios of hydrophilic polyols used to synthesize the water-swelling water-proof polyurethane elastomers and the relative molecular mass of related polyols were defined through the selective experiments. The types and ratios of fillers and coupling agents were also selected by the contrast experiments. The water-proof elastomers with comprehensive performance superior to those of the commercial similar products at home and abroad were studied and prepared.
