摘　　要：研究了低泡表面活性剂在经济型建筑涂料中的应用。将低泡表面活性剂应用于涂料配方中,测试了涂料的展色性、耐水性、遮盖力、光泽、泡沫和耐擦洗性,并和传统的烷基酚类表面活性剂X-100进行了对比。使用低泡表面活性剂的涂料在遮盖力、光泽、展色性和耐水性方面都可以满足经济型建筑涂料的要求,且和传统烷基酚类表面活性剂相比没有明显的差异;使用低泡表面活性剂的涂料泡沫不明显,但使用传统烷基酚类表面活性剂会导致明显的涂料泡沫;使用低泡表面活性剂的涂料,其涂膜的耐擦洗性都可以满足建筑涂料的要求。本实验研究的低泡表面活性剂都是环境友好型的非离子表面活性剂,均可应用于经济型建筑涂料的配方开发。The application of low foam surfactants in economical architectural coatings was studied.Low foam surfactants were applied in coatings formulas.Color development,water resistance,hiding,gloss,foam and scrub resistance of the coatings were tested.The test result was compared with that of conventional alkylphenol surfactant.The coatings with low foam surfactants can meet the requirements of economical architectural coatings in terms of hiding,gloss,color development and water resistance,and there was no significant difference between these surfactants and conventional alkylphenol surfactant.The foam of the coatings with low foam surfactants was not obvious,while the foam of the coatings with conventional alkylphenol surfactant was obvious.The scrub resistance of the coatings films with low foam surfactants can meet the requirements of architectural coatings.The low foam surfactants studied in this experiment are environmentally friendly nonionic surfactants,which can be used in economical architectural coatings formula development.
