制备条件对聚酰胺蜡触流变剂性能的影响

摘要研究了聚酰胺蜡粉末的粒径和活化试剂的种类对聚酰胺蜡触流变剂改善涂料流变性能的影响。在环氧树脂体系中，与未研磨的聚酰胺蜡相比较，研磨后的聚酰胺蜡使体系具有更好的流变性能。考察了活化剂正丁醇、异丙醇、乙醇和甲醇的加入对聚酰胺蜡流变性能的影响，发现将乙醇与异丙醇按质量比5∶7复配后活化的聚酰胺蜡浆，能使环氧树脂体系具有更高低剪切黏度和更低高剪切黏度的触流变性能。

Abstract： The effects of particle size of polyamide wax power and the types of activators on the rheological properties of coating improved through polyamide wax rheological modifier were studied. The results showed that fully grinding of polyamide wax would make the performance of rheology better in epoxy resin system than that without any grind of polyamide wax. The influence of rheological properties were investigated through the addition of activators including n-butyl alcohol, isopropyl alcohol, ethanol and methanol to polyamide wax, and it was found that the touch rheological properties in the epoxy resin system had a higher low shear viscosity and lower high shear viscosity when polyamide wax slurry activated was compounded by ethanol and isopropyl alcohol with ratio of 5∶7.

Keywords： polyamide wax activator thixotropic property viscosity
