A styrene–acrylic copolymer emulsion containing hydroxyl-phosphate as flash-rust functional monomer and hydroxypropyl acrylate as cross-linking monomer was synthesized. The effects of the hydroxyl phosphate dosage, the hydroxypropyl acrylate dosage as well as the ratio of soft to hard monomer on the emulsion and coating film were investigated. The results showed that the emulsion of 4% hydroxyl phosphate function monomer and 3% hydroxypropyl acrylate with soft and hard monomer ratio of 1:1.6 and modified emulsion and amino resin ratio of 6:1 resulted in a coating film with the best performance. 相似文献

Statistical methods were used to develop hydroxy functional acrylic emulsions for use with a water-dispersible polyisocyanate
crosslinker. The resulting two-component waterborne coating systems were optimized for kitchen cabinet and office furniture
applications. Key performance criteria included appearance and aesthetics, pot life, print and mar resistance, and chemical
resistance involving both Kitchen Cabinet Manufacturers’ Association (KCMA) and office furniture requirements. Statistical
analysis revealed several strong correlations between acrylic emulsion hydroxy level, particle size, composition Tg, polymerization process and wood coating performance. For example, smaller acrylic emulsion particle size was found to yield
many performance benefits with few detriments.
Coating formulation variables were also found to be significant. Ultimate coating hardness increased with water-dispersible
polyisocyanate level, yet early hardness readings correlated negatively with water-dispersible polyisocyanate level. Plasticization
and crosslinking effects were thought to be responsible. A higher ethylene glycol monbutyl ether (EB) coalescent level was
found to correlate negatively with coating hardness, suggesting a reaction between the EB hydroxyl group and the water-dispersible
polyisocyanate, resulting in plasticization of the coating.

羟基磷酸酯共聚苯丙乳液的合成及其防腐性能 总被引:1,自引:0,他引:1
低温条件下,用甲基丙烯酸缩水甘油酯(GMA)和浓磷酸制备一种羟基磷酸酯功能单体,将其与丙烯酸酯类单体共聚制备一种功能性苯丙防锈乳液,对该改性苯丙乳液及其涂膜进行了性能测试,并采用IR、SEM、Tafel和粒径分析进行了表征。结果表明,所制备的乳液反应体系稳定,乳液粒径约为100 nm,粒径分布均匀并具有窄分布的特点;当羟基磷酸酯用量为单体总质量的4%时,其漆膜的耐水性及耐盐雾性能达到最佳,无闪蚀现象,腐蚀电流较小,为1.376×10-8A,说明涂层的耐腐蚀能力较强。 相似文献
