以3种不同粒径的规格型号为CC–1250,CC–2500和CC–6000的超细Ca CO3替代20%的联苯胺黄颜料应用于ABS黄色母粒中,研究了这3种超细Ca CO3对ABS黄色母粒色彩性能的影响。结果表明,超细Ca CO3粒子的粒径越小,其对色母粒的色彩性能影响越小;由含有粒径最小的CC–6000型超细Ca CO3的色母粒所制备的ABS样板反射率曲线及明度值与未加超细Ca CO3的最为接近,且两者的色差最小;由含有CC–6000型和CC–1250型超细Ca CO3的色母粒所制备的ABS薄膜透过率曲线与未加超细Ca CO3的也最为接近。 相似文献

用纳米CaCO3和普通活化CaCO3分别替代不同比例的颜料应用于聚烯烃色母粒中,利用测色仪测定色母粒制成的薄膜和样板制品的着色力和遮盖力,研究其对色母粒色彩性能的影响,并进行比较。结果表明,在不改变被着色制品色彩性能的前提下,纳米CaCO3可以替代部分颜料,且效果略优于普通活化CaCO3。色母粒中纳米CaCO3含量为10%(质量分数,下同)时,薄膜制品的光密度最大,遮盖力最高,分散效果最好。颜料的着色力在纳米CaCO3含量为20%时提高程度最大,而且体系的分散性也得到改善。 相似文献

The color of mineral pigments changes obviously with their particle size. However, how the particle size of these mineral pigments affects the color of the mineral pigment color block remains unclear. Based on optical principles and the physical properties of mineral pigment particles, our analysis found that changes in the particle size not only nonlinearly affect the behavior of light at the first surface of the mineral pigment color block, but also affect the interaction of light with the particles within the body of the mineral pigment color block, ultimately changing the spectral reflectance and color of the mineral pigment color block. Finally, we derived a nonlinear monotonically decreasing relationship between the particle size and the spectral reflectance. The experiment conducted in this article selected six kinds of mineral pigments as color block samples and observed the changes in the spectral reflectance and color value with the particle size. These studies are beneficial for color researchers conducting scientific research related to mineral pigments. 相似文献

C.I. pigment red 170 is an important type of organic pigment. A new type of quaternary ammonium salt containing siloxane group was prepared and then used as a favorable dispersant in the surface treatment of pigment red 170. The quaternary ammonium salt was achieved from the reaction of N-(β-aminoethyl)-γ-aminopropyl-methyl-bimethoxy-silane and 3-chloro-2-hydroxypropyl-bimethyl-hexadecyl ammonium halide in isopropanol, and its structure was characterized by IR and NMR techniques. The flowability, dispersing extent, particle size, and wetting behaviors of pigment were determined and the results showed that a small amount of the above dispersant could bring to the high flowability, good dispersing stability, small particle size and excellent wettability of pigment red 170. We also proposed the scenarios of dispersing process of pigment red 170 based on the information obtained from above characterizations. 相似文献

分别通过 X射线光电子能谱仪( EDS)、 X射线衍射仪( XRD)、红外光谱( FT-IR)及透射电镜( TEM)对国内外钴蓝颜料元素成分及含量、结构、结晶性能、颜料粒子形貌及粒径分布进行了对比分析,将所选择的钴蓝颜料添加到外墙乳胶漆中,考察了不同微观形貌的钴蓝颜料对外墙乳胶漆的着色力、黏度、粒径、相容性的影响。结果表明:钴蓝颜料的初始粒径对其着色性能影响较大,初始粒径越小,其着色力越高;此外,钴蓝纳米粒子的粒径分布越窄,其在外墙乳胶漆中的分散能力越优异,同时提高了老化性能、耐候性能, 600 h不起泡、变色 ≤1级,在耐候要求年限较高的户外涂层中可以选择搭配钴蓝颜料着色代替酞青蓝,以达到涂层保光保色性要求。 相似文献
