          摘要:現有大部分單組分聚脲防護涂料均含有顏填料,非透明,涂刷后無法觀測混凝土基層裂縫變形情況。通過不添加粉狀填料及顏料研制透明型單組分聚脲防護涂料,調整聚醚多元醇、擴鏈劑和潛固化劑摻量提高防護涂料的力學性能,利用液體止流劑提高涂料的抗流掛性,其力學性能優于非透明單組分聚脲防護涂料,抗流掛性較好,涂膜無色透明。

          Abstract:Most of the existing one-component polyurea protective coatings contain pigments and fillers,non-transparent,cannot observe the concrete base crack deformation after painting. The transparency of the material can be achieved by not adding powder fillers and pigments,the type and amount of polyether polyols and Isocyanate can be adjusted to improve the mechanical properties,and the anti-sagging property of the material can be improved by using liquid flow-arresting agents. To prepare a transparent one-component polyurea protective coating with better mechanical properties than non-transparent one-component polyurea protective coating,with better anti-sagging property and colorless and transparent film.
          Key words:transparent,one component,polyurea protective coating
