聚氨酯密封剂改性方法研究进展

Research progress on modified methods for polyurethane sealants

介绍了近年来国内外在提高聚氨酯(PU)密封剂的力学性能、粘接性能、耐候性和施工性等方面的研究进展,主要包括通用PU密封剂的改性、SPU(端硅烷基PU)密封剂的改性和PU密封剂纳米改性等方面的内容,并展望了PU密封剂未来的研究重点和发展前景。

The recent research progress of improving some properties （such as mechanics properties, bondingproperties, weather-resistance and workability ） for polyurethane （PU） sealants was introduced at home and abroad. The main contents include modified general PU sealants, modified SPU （PU terminated by silane） sealants, and PU sealants modified by nano-materials. And the future research emphasis and development prospects of PU sealants were expected.
