摘　　要：针对环境因素对粉石英基生态涂料甲醛净化性能的影响进行了研究。正交试验结果表明,环境因素影响大小为湿度>光照强度>温度,高湿度下甲醛净化率比低湿度下高不超过4%;适中的光照强度能获得较好的甲醛净化率;随温度升高甲醛净化率略有升高;涂料中的多孔材料能有效吸附甲醛,负离子粉释放的负氧离子能有效氧化甲醛,使得涂膜在夜间仍具有很高的净化率,高达93%;粉石英显著改善了二氧化钛的分散效果,增大了反应比表面积,提高了涂料的甲醛净化率和净化速率。总的说来,这些因素对粉石英基生态涂料甲醛净化率影响不超过5%,粉石英基生态涂料能应用于广大地区,有效消除室内甲醛危害,保障人们的身体健康。The influence of environmental factors on the formaldehyde purification rate （ FPR ） of konilite based ecological coatings （ EKC ） was studied. The orthogonal tests results showed that the magnitudes of influence of the factors were in the order of humidity （ 5% ） 〉 light intensity （ 3.6% ） 〉 temperature （ 2.7% ）. The FPR in the high humidity condition was higher than that in low humidity condition by no more than 4%; a better FPR was achieved in the condition of a moderate light intensity; as the temperature rose, the FPR increased slightly. Moreover, the EKC could maintain a high FPR of 93% at night because porous materials in the coatings can absorb formaldehyde protect human health
