摘要
分别研究了不同增稠剂对多颜料配方涂料及涂层性能的影响。增稠剂用量的增加会不同程度地增加涂料体系的黏度,尽管不同程度的出现了高剪切增稠现象,但是并不改变涂料的假塑性流体特性。所有配方的弹性模量均高于黏性模量,而且相位角均不超过30°,而且同一增稠剂的配方2的黏弹模量更大。涂层光泽度和拉毛强度变化要显著于其它物理值。
The effects of thickening agent on the coating color and coating film characteristic are discussed in this article. The testing results with AR550 rheometer indicate that thickening agent has influence on apparent viscosity , but don not change the pseudoplastic behavior, though it demonstrates varing degrees of shear-thickening at high shear-rate. The storage modulus G＇of all formulations are higher than viscous modulus G＂, the viseo-elastie modulus of formula 2 is superior to formula 1 for a special thickening agent, also the phase angle 8 is less than 30°. The gloss and IGT are more appreciable impacted by thickening agent than other physical properties.
