聚脲复合涂层材料的改性和耐老化性能研究
Study on Modification and Aging Resistance of Polyurea Composite Coating Materials
摘要
Abstract
The protection repair coating materials can prevent corrosion medium into hydraulic concrete and improve the durability of hydraulic concrete.Against the special climate and hydrological environment of high intensity ultraviolet radiation and frequent freeze-thaw cycle in western alpine-cold region of China,the developed polyaspartate polyurea is modified by mixing nano TiO2,anti-aging agent,moderate dispersing agent,defoamer and silane coupling agent.Comparing with polyaspartate polyurea,the anti ultraviolet ageing performance of this polyurea composite coating material is improved,and its bonding property,toughness,low temperature flexibility are excellent,which can meet the basic requirements of protection repair coating materials in western alpine-cold region.关键词
