厚质建筑涂料保色耐污性能常用测试方法比较

Comparative Study of Typical Test Methods for Color Retention and Antifouling Performance of High Build Archtectural Coatings

由于厚质建筑涂料应用广泛,所以对其涂层耐气候老化后的保色耐污性能要求高。本研究采用自然气候曝晒试验、人工加速老化试验、耐沾污性试验、耐雨水污痕试验和户外涂装墙试验5种方法对两种厚质建筑涂料(多彩涂料和真石漆)进行检测,考察其保色、耐污性能,并对5种测试方法的结果进行了比较,为厚质涂料的应用提供了有益参考。

Due to the wide application of high build architectural coatings,the requirements for color retention and stain resistance of the coatings after weathering aging are strict.In this article,five methods such as natural climate exposure test,artificial accelerated aging test,stain resistance test,rain stain resistance test and outdoor wall coating test are adopted to test the color retention and stain resistance of the high build multicolor architectural coatings and stone-like coatings.The results of the five test methods are compared,which can be useful for the application of high build coatings.
