摘要：

研究了添加松香及其改性氢化松香甘油酯、氢化松香季戊四醇酯、松香改性对特辛基苯酚树脂对以油酸甲酯为介质的12.5%氰霜唑·吡唑醚菌酯可分散油悬浮剂物理稳定性及流变特性的影响。傅里叶变换红外光谱表征结果表明,与松香酸相比,氢化松香甘油酯、氢化松香季戊四醇酯和松香改性对特辛基苯酚树脂的羧基吸收峰消失且出现酯基的特征吸收峰。实验中,随加成烷基醇碳链的延长,软化点升高。且随着树脂的质量分数增加,制剂的粘度提高,物理稳定性也相应提高(析油率降低)。流变结果表明,添加松香改性树脂的可分散油悬浮剂体系呈正触变性,且树脂种类对体系的屈服值影响较大,具体表现为:松香改性对特辛基苯酚>氢化松香季戊四醇酯>氢化松香甘油酯>松香,制剂的物理稳定性也呈现相同的趋势。因此,松香改性树脂具有作为可分散油悬浮剂物理稳定剂的应用潜力。

Abstract:

Cyazofamid-pyraclostrobin (12.5%) oil dispersion was prepared by using methyloleate as the dispersing medium. The influence of adding hydrogenated rosin glycerin ester(HRGE), hydrogenated rosin pentaerythritol ester(HRPE) and rosin modified 4-tert-octylphenol resin (RMOR) on the physical stability and rheological behavior of the oil dispersion were investigated, respectively. The results of Fourier transform infrared spectroscopy (FTIR) indicated that the absorption peak of HRGE, HRPE and RMOR disappeared, meanwhile, the absorption peak of ester group was observed compared with rosin. This indicates that the softening point of different resin increases with the extension of carbon chain in their molecular structures. Moreover, the viscosity and the physical stability of the oil dispersion increase(lower oil separation ratio) with the increasing mass fraction of resin. The rheological tests show that the positive thixotropy is observed for the oil suspension prepared with modified resin. However, the oil suspension prepared with different resins significantly differs in the yield value, presented as RMOR>HRPE>HRGE>RA. The physical stability of different oil suspensions exhibits the same tendency. In conclusion, modified resins are capable of serving as the anti-settling agents in the preparation of oil dispersion of pesticides.

Key words: resin, oil dispersion, rheological characteristics, physical stability
