摘　　要：本研究采用自制硅树脂进行配方设计,开发出一款彩色可呼吸材料。涂装前对混凝土基材先涂装一层以碱金属硅酸盐为主的底漆,防止混凝土掉灰、起粉,通过底漆和色漆两道施工达到混凝土表面防护和美化功能兼备的可呼吸混凝土防护材料体系。其在拥有良好疏水防护和水分挥发性能的同时,具有一定的渗透能力,与混凝土反应并以化学键牢固结合,能够对混凝土外观进行修复和美化,解决了涂装后混凝土在服役中所产生因内部水分挥发不良或冻融循环造成的剥落起皮等问题。该彩色可呼吸材料在实际应用中效果优异,取得良好的经济和社会效益,应用场景广阔。This study used self-made silicone resin for formula design and developed a colored breathable material.Before painting,a layer of alkali metal silicate based primer should be applied to the concrete substrate to prevent the concrete from falling off dust and powder.Through two layers of primer and color paint construction,a breathable concrete protective material system with both surface protection and beautification function was achieved.It had good water repellent protection and moisture evaporation performance,as well as a certain degree of penetration ability.It reacted with the concrete and firmly bound with chemical bonds,which could repair and beautified the appearance of the concrete.It solved the problems of peeling and flaking caused by poor internal moisture evaporation or freeze-thaw cycles during the service of coated concrete.This colored breathable material has excellent performance in practical application,and achieves good economic and social benefits.It has a wide range of application scenarios.
