羟基增塑剂对氨基甲酸酯淀粉与 PVA 混合浆相分离行为的影响
Effect of hydroxyl-containing plasticizers on the phase-separation behaviors of carbamate starch/PVA blended pastes
摘要
Abstract
The influences of some hydroxyl-containing plasticizers with different number of hydroxyls on the phase-separation behaviors of carbamate starch and polyvinyl alcohol blend pastes were quantitative-ly evaluated in terms of initial demixing time and subsidence ratio.The hydroxyl plasticizer such as butyl alcohol,1,2-propanediol,glycerol,pentaerythritol ,xylitol,and sorbitol was individually mixed with the blended pastes.The experiment results demonstrated all the hydroxyl-containing plasticizers could ef-fectively increase the blended paste stability.The plasticizers enhanced the blended paste stability with increasing the number of hydroxyls up to 3,reaching maximal effect,and beyond this number it reduced again.Moreover,the influences of the amounts of glycerol,polymerization degree and alcoholization de-gree of PVA were also investigated.关键词
