研究了聚乙烯蜡、硬脂酸锌和硅烷偶联剂对酞菁蓝颜料分散性能的影响,并对色母粒的耐候性进行了考察。结果表明聚乙烯蜡用量为颜料用量的0.5倍时,分散效果较好,耐候老化前后颜色色差变化小,耐候性能较好;加入硬脂酸锌进一步改善了颜料的分散效果,但硬脂酸锌用量增加,色差变化大,耐候性变差;采用硅烷偶联剂对酞菁蓝颜料颗粒进行表面处理,改善了颜料的分散性,其中长链硅烷效果较好,而且色母粒的耐候性和草丝断裂拉力有显著改善。草丝的拉伸断面扫描电镜(SEM)分析表明,硅烷偶联剂对酞菁蓝颜料的分散起到了促进作用。 相似文献

Comparison of the efficiency of inorganic nonmetal pigments with zinc powder in anticorrosion paints
This paper deals with the study of properties of anticorrosion pigments of varying chemical composition in epoxyester paints. Two type lines of paints were prepared. The first line comprised an anticorrosion pigment with a PVC concentration of 10% while the other line comprised an anticorrosion pigment with a PVC concentration = CPVC. The following nontoxic anticorrosion pigments were observed: zinc phosphate, zinc phosphomolybdate, calcium hydrogen phosphate, zinc phosphate modified with an organic corrosion inhibitor, strontium–aluminum polyphosphosilicate, zinc–aluminum polyphosphate, calcium metaborate, calcium ferrite, calcium borosolicate, and strontium chromate. The epoxyester primers were observed for the effect of the type of pigment on the anticorrosion properties. Anticorrosion efficiency was derived from tests in a condenser chamber and in a salt spray cabinet as well as from a test of chemical resistance of pigmented coatings. The evaluation of anticorrosion efficiency of inorganic nonmetal pigments was carried out by means of comparison with anticorrosion efficiency of metal dust. 相似文献

AbstractCeramic pigments based on the perovskite structure develop a promising red hue and furthermore present no environmental or health problems. Pigment colouring efficiency was tested in different ceramic applications, both in the body and in glazes. Final products, with variations in both maximum firing temperature and soaking time, were characterised by colorimetry. The investigation focused on the factors and mechanism influencing perovskite dissolution by calculating phase compositions of different ceramic matrices and observing pigment microstructure. Pigment powders were also characterised by structural analysis and spectroscopy. Pigment dissolution was only slightly affected by the firing cycle, mostly being governed by the amount and chemical composition of the liquid phase. In particular, the larger the content of chemically aggressive components such as calcium, magnesium, zinc and lead oxides, the stronger and faster the pigment dissolution. 相似文献

Photocatalytically active titanium dioxide and zinc oxide are used as a white pigment for cosmetics, leading to decomposition of a certain degree of sebum on the skin upon exposure to the ultraviolet radiation in sunlight. Herein, as novel white pigments for use in cosmetics, titanium‐zinc phosphates were prepared from titanium sulfate, zinc sulfates, and phosphoric acid. The chemical composition, powder properties, photocatalytic activity, color phase, smoothness, and acid resistance of the titanium‐zinc phosphates were evaluated. Samples prepared at high titanium ratio were easy to be amorphous phase, on the other hand, samples prepared at high zinc ratio indicated the X‐ray diffraction peaks of zinc phosphate dihydrate. The photocatalytic activity of these titanium‐zinc phosphate particles was low; thus these pigments should not induce decomposition of sebum on the skin. All samples prepared in this study exhibited high reflectance within the range of visible light. The substitution with titanium is effective to improve acid resistance of zinc phosphate white pigments. 相似文献

This paper describes the study of a pink ceramic pigment based on the optical properties of Cr-doped structures, having into account environmental considerations. The research is focused on the optimisation of the synthesis parameters in order to minimise the amount of pollutant Cr(VI) in the washing liquids and enhance chromatic coordinates. In a first stage, the Al2−xCrxO3 solid solution was studied. Nevertheless, the observation that ZnO was required in the frit to stabilise the pink colour after glazing made us to conduct the research towards the optimisation of the ZnAl2−xCrxO4 system. X-ray diffraction (XRD) indicates a solid solution formation based on the gahnite structure; moreover, no Cr(VI) and B contents were found in the analysis of the washing liquids. Thus, this research enabled us to produce a pink pigment with low environmental impact and good chromatic coordinates. Further study of the pigment applied in a glaze showed evidence of the importance of the glaze composition for the colour development and stability of the ceramic pigments. 相似文献
