摘要
研究了复合悬浮剂的加入量为0．4％～3．2％．对醇基涂料的悬浮性、粘结性和高温抗裂性的影响规律。结果表明：加入一定量的复合悬浮剂比相同量的单一悬浮剂（锂基土或有机土）的效果更好。具体表现是：复合悬浮剂的悬浮性更好，涂料能维持72h不出现明显的分层现象；随着复合悬浮剂加入量的增多，涂料的悬浮性增强，但黏度升高，高温抗裂性下降。
The effect of composite suspending agent （ e. g., 0. 4% - 3.2% ） on the perform- ance including suspending property, viscosity and high temperature crack resistance of alcohol -based coatings is analyzed. The results show that the performance of the composite suspending agent is better than the single suspending agent （e.g. ,lithium-bentonite or Organic -bentonite） at the same dosage.The composite suspending agent shows better suspending prop- erty with no delamination occurred within 72 h, meanwhile, it can allow the resulted coatings to show improved suspending property, viscosity and high temperature crack resistance.
