分散剂在塑料着色中的应用

Application of Dispersant TAS-A in Plastics Colouring

采用塑料分散剂TAS A与颜料共混用于聚丙烯着色 ,研究了分散剂TAS A对聚丙烯着色效果的影响。结果表明 :分散剂TAS A可部分取代颜料 ,降低颜料用量 ,有利于颜料的均匀分散 ,提高了塑料制品的外观质量。

The mixture of plastic dispersant TSA-A and pigments was applied to the colouring of PP. The basic acting mechanism of the dispersant TSA-A in the plastics colouring was studied,and the effect of the plastic dispersant TSA-A on the colouring of PP was also studied. The results showed that the pigments could be replaced partly by the plastic dispersant TSA-A, and the added amount of the pigment could thus be reduced, resulted in improving the dispersion of the pigments in the plastics and the appearance quality of the plastics product.
