摘要:

对色母粒专用钛白粉进行了相关研究,分别以包膜剂种类、加量为变量,考察了常规性能、树脂体系、耐温和耐候性能,最后分析了相关的原理。结果表明,增加包膜剂加量,常规指标中干粉白度、吸油量下降,而挥发分升高,三羟甲基丙烷(TMP)包膜的最高白度可达97.64,优于其他样品,而在聚丙烯(PP)树脂体系中,b*值出现下降趋势;在耐温体系下,TMP的表现优于其他3个体系,在较低包膜量(≤0.5 %)的情况下,TMP样品优于标样;耐候体系中,TMP加量为0.5 %和0.7 %时其性能优于标样;TMP包膜剂的效果较好,主要是由于TMP官能团较多,能较好地包裹在钛白粉的表面。

Abstract:

In this paper, the titanium dioxide for color masterbatch was studied, and their conventional properties, resin system, temperature and weather resistance were investigated with the type and amount of coating agent as variables. Moreover, the relevant mechanisms were analyzed. The results indicated that the whiteness and oil absorption of trimethylol propane(TMP) decreased with an increase of coating agent content, whereas the volatile matter increased. The maximum whiteness of TMP coating reached 97.64, which was better than those of the other samples. In the PP resin system, the b* value decreased. The performance of TMP was better than the other three systems in the temperature resistant system, and it was also better than that of the standard sample at the coating content lower than 0.5 %. In the weathering system, the samples containing the TMP dosage of 0.5 and 0.7 wt % were better than the standard one. These results may be attributed to the fact that TMP has more functional groups, and therefore it can better wrap on the surface of titanium dioxide.

Key words: masterbatch, titanium dioxide, organic coating agent, weatherability, resin system
