灰色颜料的配制及其太阳热反射性能的影响因素分析 总被引:1,自引:0,他引:1
《电镀与涂饰》2015,(22)
基于三原色混色机理将不同的红、黄、蓝颜料混合,配制出不同的灰色颜料,并与纯丙乳液混合制成太阳热反射涂料。利用色差仪和紫外/可见/近红外分光光度计测试涂层的色空间值L*、a*、b*与太阳热反射率,考察了颜料组分、用量以及添加第二相粒子对涂层太阳热反射性能的影响。结果表明,类似色度下,着色力高的氧化铁红、钛铬棕的用量比着色力低的锆铁红、镨黄少;铁铬黑、钴黑这2种无机黑降低涂层明度的同时会严重减弱反射率。为获得反射率较高、明度较低的涂层,使用的颜料需折射率和反射率均较高且明度较低。 相似文献

The effect of different shape and size of pigments in blends on latex coating surface properties was investigated. Two pigment blends were compared. Both blends were made of plate-like kaolin pigment but with different size prismatic precipitated calcium carbonate at different volume ratios. All coatings were applied on absorbent as well as non-absorbent substrates. Surface coating properties investigated include surface morphology, surface chemistry and surface energy. Surface morphology was characterized by measuring gloss and roughness, surface chemistry was characterized by X-ray Photoelectron Spectroscopy and surface energy was estimated by Kaelable approach. 相似文献

The influence of pigment shapes and pigment blends on the surface energy was investigated and compared with the surface chemistry
of pigmented latex coatings. The coatings were made of different volume ratios of two pigments: plate-like kaolin clay pigment
and prismatic precipitated calcium carbonate (PCC) pigment. These were mixed together with carboxylated styrene–butadiene–acrylonitrile
latex (SBA), and applied over nonabsorbent substrates as well as absorbent substrates. The composition of the surface of the
coatings was investigated by X-ray photoelectron spectroscopy (XPS). Two approaches were used to estimate the total surface
energy and the components of the coatings: a conventional approach—“the Kaelble approach”—and a more modern approach—“the
van Oss approach.” Pigment blends with different shapes and increments caused a change in the surface chemistry and the surface
energy of the latex coatings. As the prismatic PCC pigment particles increased in the kaolin/SBA coating system, the SBA latex
content at the coating surface increased and the total surface energy of the coating decreased. This is valid for both nonabsorbent
as well as absorbent substrates. It was found that there was a strong correlation between the surface energy and the surface
composition. The surface energy of the coatings estimated by the Van Oss approach was always lower than that estimated by
the Kaelble approach. Colloidal interactions between pigment–pigment and/or pigment–binder were thought to play an essential
role in determining the final coating surface energy and its components. Changes in the surface latex content and the surface
energy due to the different pigment blends investigated were found to fit straight-line equations. 相似文献

Green pigments with high near infrared reflectance based on a Cr2O3-TiO2-Al2O3-V2O5 composition have been synthesized. Cr2O3 was used as the host component and mixtures of TiO2, Al2O3 and V2O5 were used as the guest components. TiO2, Al2O3, and V2O5 were mixed into 39 different compositions. The spectral reflectance and the distribution of pigment powder were determined using a spectrophotometer and a scanning electron microscope, respectively. It was found that a pigment powder sample S9 with a Cr2O3-TiO2-Al2O3-V2O5 composition of 80, 4, 14 and 2 wt%, respectively, gives a maximum near infrared solar reflectance of 82.8% compared with 49.0% for pure Cr2O3. The dispersion of pigment powders in a ceramic glaze was also studied. The results show that the pigment powder sample S9 is suitable for use as a coating material for ceramic-based roofs. 相似文献
