Abstract

A method for production of polyurethane coatings with low surface energy modified with a block copolymer polydimethylsiloxane–polyphenylsilsesquioxane is presented. Surface characteristics of coatings were studied by methods of measuring the contact angle, attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy and scanning electron microscopy with X-ray spectral microanalysis, and the values of static contact angles and surface energy were obtained. The effect of pigmentation on wetting and physicomechanical characteristics of low-energy coatings has been investigated.

基于丙烯酸共聚物和有机硅嵌段共聚物改性多异氰酸酯的低表面能聚氨酯涂料

摘要

提出了一种用嵌段共聚物聚二甲基硅氧烷-聚苯基倍半硅氧烷改性的低表面能聚氨酯涂料的生产方法。通过测量接触角、衰减全反射傅里叶变换红外(ATR-FTIR)光谱和扫描电子显微镜结合X射线光谱微量分析等方法研究了涂层的表面特性，得到了静态接触角和表面能值。已经研究了色素沉着对低能涂料的润湿和物理机械特性的影响。
