建筑与环境设计用水性聚氨酯涂料的应用现状及研究进展

随着环保意识的不断增强,环保功能型水性聚氨酯建筑用涂料备受青睐。总结了近几年国内外功能型水性聚氨酯涂料在建筑与环境设计行业中的应用现状和最新研究进展。水性聚氨酯涂料具有水性涂料的环保性和聚氨酯涂料的高性能,被广泛应用于建筑与环境设计行业,主要有防水涂料、耐污防腐涂料、防霉抗菌涂料、耐磨抗冲击涂料和阻燃隔热涂料。由于水性聚氨酯分子中引入了亲水基团,导致其防水性、耐污性、防腐性、防霉抗菌性、耐磨抗冲击性及阻燃隔热性等较差,一定程度上限制了其应用范围。为了解决这一问题,研究者们对水性聚氨酯涂料进行了纳米改性、复合改性、交联改性和共混改性等。综述了近年来,国内外学者在水性聚氨酯涂料改性方面的研究进展,并结合目前国内水性聚氨酯的发展水平,提出了未来水性聚氨酯涂料的主要研究方向为通过表面改性的方法开发高性能、高品质产品,从而实现建筑与环境设计对水性聚氨酯涂料高性能、功能化、本性化、环保安全性以及装饰性的要求。

Application Status and Research Development of Waterborne Polyurethane Coatings in Architectural and Environmental Design

As the environmental awareness increases continuously, environmentally friendly functional waterborne polyurethane architectural coatings are favored. The application status and the latest research progress of functional waterborne polyurethane coatings in the construction industry in recent years have been summarized. Water-borne polyurethane coatings are widely used in the construction industry due to environmental protection of water-based paint and high performance of polyurethane coating, and mainly include waterproof coating, anti-corrosion coatings, anti-mildew coatings, abrasion resistant coatings and fire retardant coatings. Due to the introduction of hydrophilic groups into the water-borne polyurethane molecules, water resistance, stain-resistance, anti-corrosion, antifungal and antifungal properties, abrasion and impact resistance deteriorates and the application range is limited in some certain. To solve this problem, nano-modification, compound modification, cross-linking modification and blend modification on waterborne polyurethane coatings were conducted by researchers. The main research direction of future waterborne polyurethane coating is put forward by summarizing the research progress of domestic and foreign scholars for waterborne polyurethane coatings in recent years and combining the development level of domestic waterborne polyurethane, which aims to develop high performance and high quality products by the method of surface modification so as to meet high performance, function, nature, environmental safety and decoration requirements of waterborne polyurethane coating in architectural and environment design.
