摘要
对粉煤灰应用于单组分高强度聚氨酯防水涂料中进行了可行性分析,研究了粉煤灰在粉体填料中的含量对防水涂料各项性能的影响。结果表明:防水涂料的拉伸强度、断裂伸长率以及直角撕裂强度均随着粉煤灰含量的增加呈现先增加后降低的趋势,当粉煤灰含量为30%时,防水涂膜的各项性能均达到最优。
Feasibility analysis of fly ash applied in one component high strength polyurethane waterproofing coating is carried out,and influences of content of fly ash in powder filler on performances of waterproofing coating are studied.The results show that tensile strength,elongation at break and right angle tearing strength of the waterproofing coatings increase first and then decrease with the increase of fly ash content.When the content of fly ash is 30%,the performances of the waterproofing coating reach the best.
