Fourteen pigments based on 2,4-diamino-bis(anthraquinonylamino)-6-phenyl-1,3,5-triazine with chloro, methyl and methoxy substituents on the phenyl ring and with methyl or benzoylamino groups on one or both anthraquinone nuclei have been prepared. The shades of the pigments in PVC films using the CIE system of tri-stimulus values are described and the fastness properties of the pigments have been evaluated in PVC films, oil paints and baking enamels using visual assessment of colour changes. It was found that the type and the position of the substituents have a significant affect on the shade and fastness properties of the pigments studied. Benzoylamino groups and unsymmetrical substitution also have an unfavourable influence on fastness to solvents. Some other possible factors are discussed. 相似文献

黑色陶瓷颜料目前被广泛应用于陶瓷装饰领域,其传统制备工艺需加入氧化钴,但氧化钴的高价限制了黑色陶瓷颜料的发展,因此开发无钴黑色陶瓷颜料成为陶瓷颜料研究领域的热点之一,而尖晶石型无钴黑色陶瓷颜料因其出色的耐高温性、气氛适应性和化学稳定性受到众多研究者的青睐。本文基于尖晶石型无钴黑色陶瓷颜料的相关研究进展,围绕其呈色机理、制备原料种类和制备工艺等方面进行了详细的阐述与分析。目前,制备该类陶瓷颜料的原料主要分为化工原料、矿物原料和工业固废,制备工艺则主要包括传统高温固相法、微波焙烧法、化学沉淀法、溶胶-凝胶法、微乳液法、溶液燃烧法等,所制备颜料的呈色性能主要受原料组成中过渡金属元素之间摩尔比、焙烧温度和保温时间的影响。相较而言,采用微波焙烧工业固废制备该类陶瓷颜料具有良好的应用前景,但制备过程中尖晶石形成规律和演变机理以及工业固废所引入的杂质组分对颜料性能的影响还有待进一步研究。 相似文献

The presented review will introduce the use of effect pigments as a powerful tool for the functionalization of textiles. This review starts with a short introduction on the basics of effect pigments and their properties. Subsequently, some principles of effect pigment application onto textiles and the interaction of pigment to binder systems are reported. Different possible functionalizations realized on textiles are presented. Four main types of application are discussed: optical properties, electrical properties, barrier coatings, and antimicrobial applications. Also a view of some prospective anisotropic materials is given. Altogether it is shown that the application of effect pigments can be a powerful tool to realize functional textiles for a broad range of applications in different fields. 相似文献

Utilizing waterborne epoxy resin as a main film-forming material, a kind of light color antistatic and anticorrosive waterborne
epoxy coating with volume resistivity of 106 was prepared by adding light color conductive pigments and anticorrosive pigments. The coating has excellent corrosion protective
and outstanding decorating properties, which is applicable for the inner coating of oil tank. The effects of the type and
the amount of conductive pigments, the film thickness, the curing temperature, and the curing time on the volume resistivity
of the film were discussed. The properties of the several kinds of waterborne epoxy resin were compared and the determining
of anticorrosive pigments was discussed. 相似文献
