以丙烯酸(AA)、丙烯酸丁酯(BA)和甲基丙烯酸二甲胺乙酯(DM)为单体,合成了AA-BA-DM三元共聚物分散剂,研究了其对二氧化钛颜料的分散效果;讨论了分散剂黏度、分散剂用量对颜料分散体系的影响;同时考察了该共聚物分散剂对不同颜料的分散稳定性。结果表明,当n(AA):n(BA):n(DM)=1.25:1:0.15,引发剂占单体总质量的1%,链转移剂占单体总质量的4%,为聚合物分散剂的最佳合成条件,所得共聚物分散剂对二氧化钛分散效果最佳,分散力达97.5%,且分散剂的用量占颜料总质量的0.80%时分散效果较好。通过对酞菁绿、二氧化钛及铬红分散效果的考察,该分散剂对颜料酞菁绿的分散效果最好,二氧化钛次之,对铬红的分散效果较差。 相似文献

We developed CuO and CeMo microcontainers, which were filled with Bromosphaerol (CuO (BR)), Sea-Nine 211 (CuO (SN)) and 8-Hydroxyquinoline (CeMo (8-HQ)). We created coatings on metals using the basic resins we took from the WILKENS and Re-Turn companies without additives of the companies. The coatings were studied in the laboratory after exposure to marine environment in Mikrolimano harbor in a distance of 12 km southwest from the city of Piraeus in the east coast of the Saronic Gulf (WILKENS) and Singapore harbor (Re-Turn). Laboratory measurements showed that CeMo (8-HQ) coatings exhibit better anticorrosion stability of paints in sea water than commercial paints. With regard to the incorporation of CuO (BR) into commercial paints, the results showed a drastic improvement in antifouling behavior from that resulting from commercial paints. The contact angle with water is improved by Θ = 70° to Θ = 115° possible through morphology of the surface due to the effect of the incorporation of microcontainers ensuring a better cruising behavior of the ship. This entails a dramatic rise in cruising speed, reducing fuel consumption and reducing air pollution. The technology was tested by the partial painting of two ships with our technology, one ship which traveled for a year in the Adriatic Sea (Sea Anemos) and the other traveled over a year in the Nord Sea (Berge Arzew). 相似文献

The effect of pigment content and the nature of the solvent on the thixotropic properties of synthetic yellow iron oxide in alkyd paints have been studied by viscometry. The degree of thixotropy of a paint has been calculated from the area of the thixotropic loop. The thixotropic effect in these paints is found to appear at about 35% PVC content and increases with the level of pigmentation up to 55 to 60% PVC content. The degree of thixotropy of paints also depends on the nature of the solvents used in the formulation. Interactions between pigment and solvent and between alkyd and solvent help in building structure and consequently in developing thixotropy in yellow iron oxide-alkyd paints. The shear dependence has been analysed using the Power law and the Casson equation.These paints exhibit only pseudoplastic flow behaviour and their consistency index depends on the pigmentation level and the solubility parameter of the solvent. Sag resistance depends on the PVC content and the nature of the solvent, but the brushability property is independent of these parameters. 相似文献
