超低VOC无添加内墙底漆的研制

Preparation of Ultra-low-VOC Additive-Free Interior Wall Primer

采用低成膜温度的自交联苯丙乳液,不添加成膜助剂和二醇类防冻剂,制备了高性能超低VOC内墙环保底漆。该研究主要从乳液及其用量的选择,消泡性、贮存稳定性、抗泛碱性和附着力的改进,环保润湿剂和防霉杀菌剂的筛选等几个方面讨论了底漆的研制过程。研究结果表明:自交联苯丙乳液用量为30%,pH调节剂AMP-95和疏水改性分散剂用量分别为0.25%和1.00%时,合理选用各种颜填料和助剂,制得的底漆具有良好的消泡性、贮存稳定性、抗泛碱性和附着力等,且VOC含量不超过国标限量值的2.5%。

High performance and ultra -low -VOC interior wall environment -friendly primer was prepared using low film - forming temperature self - crosslinking styrene - acrylate emulsion, with no any coalescents and diol anti - freezer. This paper discussed the develop- ment of title product in terms of the choice of emulsion and its amount, improvement of de- foaming ability, storage stability, anti -efflorescence and adhesion, and the selection of envi- ronmental friendly wetting agents and mildew fungicides. The results showed that the primer could provide excellent defoaming ability, storage stability, anti -efflorescence and adhesion, and the VOC content less than 2. 5% of the secified limit in national standard when the self - crosslinking styrene -acrylate emulsion was fled dispersant 1.00% , as well as selected 30%, AMP-95 0. 25%, hydrophobically modi- pigments, fillers and additives.
