通过实验研究了水性涂料配方和钛白粉颜料体积浓度的关系,系统研究了钛白粉消色力、亮度及分散性等性能指标对水性涂料涂膜遮盖力、光泽和耐候性的影响。结果表明:当加入水性涂料的钛白粉颜料性能较高时,对应的水性涂料漆膜的遮盖力较高、光泽度较高,表现为正线性关系;加入的钛白粉颜料性能对水性涂料漆膜的白度和耐候性影响较小。 相似文献

以丙烯酸树脂为成膜物制备了几种户外用丙烯酸塑料涂料并测试了涂料的黄变情况.试验结果表明,在塑料表面喷涂塑料涂料能明显改善塑料底材的黄变情况,成膜物及钛白粉的种类影响涂料的黄变,紫外线吸收剂可明显改善塑料涂料的黄变情况,当紫外线吸收剂的添加量为0.3%时,黄变最弱. 相似文献

Prediction of paint properties is a critical issue for the coatings industry, since experimentation is time consuming and
a lot of financial and human resources are needed to test or develop new products. In current market conditions, cost savings
and product innovation are critical issues. In this article, an artificial neural network, of the feed forward type, was trained
using as inputs key properties of titanium dioxide and two formulation parameters (pigment volume concentration and titanium
dioxide content) for a water-based architectural coating. The outputs of this research were spread rate, color (L*, a*, b*) and tinting strength. Test data were used to check the accuracy of the model, demonstrating the viability of paint properties
prediction related to the properties of the titanium dioxide formulation with high correlation (>95%). 相似文献

以凹土代替部分二氧化钛制备涂料,通过改变凹土的用量测定涂料的性能变化情况,并对凹土进行超细粉碎处理前后对涂料性能的影响进行对比。凹土替代二氧化钛,不但可以改善涂料的某些性能,还可以降低涂料成本,但用量不宜太多,与适量的碳酸钙混合使用效果更好。相同的代替量,超细凹土优于原粉凹土。 相似文献

Anionic polyurethane ionomers as the dispersant in water‐soluble acrylic baked paint were successfully synthesized at our lab and these ionomer structures have been proven by infrared spectra. In aqueous solution, the surface tension for polyurethane ionomer molecules with different ionics was found to increase with increasing the concentration of ionics, as a result of the hydrophobics of ionomer molecules adsorbed at the air–water interface becoming even more ordered. It was also found that the viscosity is higher for polyurethane ionomer with L ‐2,5‐diaminovaleric acid hydrochloride than for polyurethane ionomer with sodium 4,4‐dihydroxy‐l‐butane sulfonate (DS200) or with dimethylol propionic acid (DMPA) in water. For the wettability and dispersion of titanium dioxide pigment present in water‐soluble acrylic baked paint, the polyurethane ionomer molecules with respective sodium 4,4‐dihydroxy‐L ‐butane sulfonate, DMPA, DS200 containing 3% 1,3‐propane sultone (ES200) and DMPA containing 3% ES200 are considered to be better dispersants. The titanium dioxide pigment was found to become finer, as the agitation time and the ionic concentration of anionic polyurethane ionomer were increased. In addition, the system with DS200 or dimethylol propionic acid will make the dispersion of titanium dioxide pigment stable in water‐soluble acrylic paint. © 2005 Wiley Periodicals, Inc.
