| 摘 要： | 以胍胶原粉(GG)为原料,正丁基缩水甘油醚(BGE)为疏水化试剂,氢氧化钠为催化剂,异丙醇为溶剂,制备了2-羟基-3-丁氧基丙基胍胶(HBPG)。通过FT-IR、XRD、TGA对HBPG结构性能进行了表征,并研究了HBPG水溶液和冻胶的流变性能。结果表明,HBPG结构中由于引入疏水基团,使其结晶度下降,热稳定性能提高,HBPG相比GG具有更好的增稠性能,且溶液稳定性能得到明显改善,HBPG制备的冻胶的流变性能优于GG,具有良好的耐温和剪切稳定性能。

| Abstract: | 2-hydroxy-3-butoxypropyl guar gum(HBPG) was synthesized with guar gum(GG) as material,using n-butyl glycidyl ether(BGE) as the hydrophobic reagent,sodium hydroxide as catalyst and isopropanol as solvent.The structure of HBPG was characterized by means of FT-IR,XRD and TGA,meanwhile,the rheological property of the aqueous solution and the gel of HBPG were discussed.The results showed that the hydrophobic modification can reduce the crystallinity and improve the thermal stability.Compared to GG,HBPG has better thickening property and the solution stability has significantly improved.The rheological property of the gel of HBPG was better than GG.The gel of HBPG has good temperature resistance and shear stability properties. |
