摘要
颜料体积浓度(PVC)指涂料中颜料所占体积比例,是影响涂料性能的关键因素之一。本文重点研究PVC对外墙涂料耐沾污性的影响规律。通过制备10种不同PVC的涂料试样,并进行耐沾污性测试,测定其反射系数下降率。实验结果表明:随着PVC升高,反射系数下降率逐渐减小,在PVC为45%时达到最低值,表明耐沾污性最佳;当PVC超过45%后,反射系数下降率急剧上升,耐沾污性能显著下降。该结论在实际工程应用中已得到验证,对优化涂料配方、提升外墙涂料耐污性能具有指导意义。
Pigment Volume Concentration(PVC)refers to the volume proportion of pigments in coatings and is one of the key factors influencing coating performance.This study focuses on the effect of PVC on the stain resistance of exterior wall coatings.By preparing ten coating samples with different PVC levels and conducting stain resistance tests,the reduction rate of the reflection coefficient was measured.The experimental results indicate that as the PVC increases,the reduction rate of the reflection coefficient gradually decreases,reaching its lowest value at a PVC of 45%,which indicates the best stain resistance.However,when the PVC exceeds 45%,the reduction rate of the reflection coefficient increases sharply,and the stain resistance performance significantly declines.This conclusion has been validated in practical engineering applications and provides guidance for optimizing coating formulations and improving the stain resistance of exterior wall coatings.
