- 摘要:
- 以氧氯化锆、乳酸及木糖醇等原料制备了一种延缓交联的交联剂——有机锆交联剂ECA1,将有机锆交联剂ECA1加入到稠化剂ECA180配制的稠化酸中得到一种高温延迟交联型交联酸,考察了交联剂反应条件、交联剂和稠化剂浓度对交联酸性能的影响,评价了交联酸的高温流变性能。实验发现,当物料配比为氧氯化锆∶乳酸∶木糖醇=1∶125∶0020 8(质量比),反应温度为50~55 ℃,反应时间为4 h时交联酸具有较好的耐温抗剪切性能,调节交联剂和稠化剂加量可改变酸液的延缓交联时间。
A delayed cross-linking agent, that is, the organic zirconium cross-linking agent ECA-1, is developed by using zirconium oxychloride, citric acid, lactic acid and so on as raw materials and a high temperature delayed cross-linked acid is generated from adding the cross-linking agent ECA-1 to thickening acid EVA-180. Analyzed are the reaction conditions of the cross-linking agent and effect of concentrations of the cross-linker and thickening agent on cross-linked acid performance and evaluated is the high temperature rheological property. The results show that the obtained cross-linked acid has good temperature-tolerate and shear-tolerate properties when the ratio of such raw materials as zirconium oxychloride, lactic acid and xylitol is 1: 1.25:0.0208 (mass ratio), reaction temperature is 50-55 ℃ and reaction time is 4 hours, and the delayed crosslinking time of acid system can be adjusted by changing dosage of the cross-linker and thickening agent.
