高效氯氰菊酯聚(N-正丙基丙烯酰胺)温敏微球的制备关键工艺研究
Study on the key preparation process of beta-cypermethrin poly (N-propylacrylamide) temperature-sensitive microsphere
摘要
Abstract
In order to develop a pesticide product for the control of Carposina niponensis Walsingham, beta-cypermethrin poly (N-propylacrylamide) (PNNPAM) temperature-sensitive microsphere was developed. Given that the volume phase transition of PNNPAM and the peak emergence of C. niponensis happen at similar temperature, the microsphere was prepared by a surfactant-free emulsion polymerization method. Effects of temperature, the concentration of N-propylacrylamide (NNPAM) and the concentration of N,N′-methylene diacrylamide (MBA) on the preparation of the microsphere were investigated. The results showed that, when the reaction temperature was 70-80 ℃, the particle size of the temperature-sensitive microsphere prepared was (601.3 ± 5.6)-(638.6 ± 8.9) nm, and the drug-loading and embedding rate of the microsphere were both relatively high. The drug-loading and embedding rate increased with the increase of the concentration of NNPAM and MBA. In addition, temperature had a significant influence on the cumulative release rate of microsphere.关键词
