摘　　要：介绍了一种基于改性溶胶-凝胶工艺的纳米二氧化硅创新技术。NANOPOL?C 784是一种用于2K PU涂料的50%(质量比)纯溶剂型纳米二氧化硅溶液。本技术的优点在于产品容易操作,可应用于各种场合,也可开发出耐机械性能极好的高光泽2K PU涂料。试验从理论到实践,给予了充分的说明。This article presents an innovative nanosilica particle technology based on a modified sol-gel process. The product used, NANOPOL C 784 from Evonik Industries AG, is a pure, solvent-based 50% w/w nanosilica composite for 2K PU coatings. The advantage of this technology is that the products are easy to handle, can be straightforwardly incorporated into a polyol matrix and can be used in a wide range of applications. This new nanosilica particle technology can thus be used in con.junction with common binders to develop high gloss, 2K PU clear coats with greatly increased resistance.
