颜料在油漆中起着着色和遮盖的作用,环氧地坪漆中宜选用耐化学介质和耐候性好的无机颜料,如钛白粉,氧化铁红,氧化铬绿,氧化铁黑,氧化铁黄,氧化锌,炭黑等,但某些有机颜料酞青蓝,酞青绿,虽存在絮凝问题,容易出现浮色,发花等现象,但由于其色彩鲜亮,着色力强,耐化学性能和耐光耐候性能良好,所以在环氧地坪漆中也经常得到应用。 环氧地坪漆填料的选用对涂层最终性能影响极大,适量的加入不仅能提高涂层的机械强度,耐磨性和遮盖率,而且能减少环氧树脂固化时的体积收缩,并赋予油漆良好的贮存稳定性,过量的加入则会增加油漆的黏度,难以流平,选用填料时,应注意填料的吸油量,酸碱性,粒度基形态等,常用的有机沉淀硫酸钡,云母粉,滑石粉和石英粉
Pigments play a coloring and covering role in the paint, epoxy floor paint should choose chemical-resistant media and weather-resistant inorganic pigments, such as titanium dioxide, iron oxide red, chrome green, iron oxide black, iron oxide yellow, zinc oxide, carbon black, etc., but some organic pigments phthalocyanine blue, phthalocyanine green, although there are flocculation problems, appearance. Floating and blooming are easy to occur, but they are often used in floor paints because of their bright colors, strong coloring power, good chemical and weather resistance. The selection of filler for epoxy floor paint has great influence on the final performance of the coating. Proper addition can not only improve the mechanical strength, wear resistance and covering rate of the coating, but also reduce the volume shrinkage of the curing epoxy resin, and give the paint good storage stability. Excessive addition will increase the viscosity of the paint and make it difficult to leveling. When choosing fillers, attention should be paid to the oil absorption, acidity and alkalinity of fillers, particle size and basic morphology of fillers, commonly used organic precipitation barium sulfate, mica powder, talc powder and quartz powder
