Abstract: 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 development of title product in terms of the choice of emulsion and its amount. improvement of defoaming ability, storage stability, anti-efflorescence and adhesion, and the selection of environmental 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 hen the self crosslinking styrene-acrylate emulsion was 30%, AMP-95 0. 25%, hydrophobically modi-fied dispersant 1. 00%o, as well as selected pigments, fillers and additives.

Key words: self-crosslinking styrene-acrylate emulsion, ultra-low-vooc, interior wall environment-friendly primer

摘要： 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%。
