摘要
(CN106212450) 本​发明​公开​了​种​改性​埃洛​石​纳米​管​复合​缓释​农药​及其​制备​方法,属于​农用​缓释​农药​技术​领域。本​发明​的​技术​方案​要点​为:(1)埃洛​石​的​提纯;(2)埃洛​石​的​有机​改性;(3)埃洛​石​复合​缓释​农药​的​制备。本​发明​制得​的​改性​埃洛​石​纳米​管​复合​缓释​农药​在​农田​中​作为​缓释​农药​使用,提高​了​除草剂、杀虫剂、抗菌剂​或​植物​生长​调节剂​的​利用率,减少​了​对​环境​和​水源​的​污染。

(CN106212450) 1. Sustained-release of the pesticide halioysite a modified nanotubes prepared composite method, characterized in comprises the steps of: Halioysite (1) purification: 100g halioysite weighed, mechanically agitating the state where it is added to 500 ml of water, 1000 ml water was added after thorough stirring continued 10min, stirred for an additional static 30min 1h, Fold lower Take sand upper layer slurry, adjusting the suspension pH to acidic, heat 15-20min, appears to be a suspension of fluff after precipitation, continues to stand for 12h, suction filtration, dried, milled 200 mesh screen to afford pure halioysite; The organic-modified halioysite (2): weight ratio of 1:50 mixed with water will halioysite, sufficiently dispersed to yield halioysite suspension, the suspension was further added 1.0% by mass of an organic modifier, a thermostatic water bath at a temperature of 65 Ć 3h 150r/min speed of the oscillator to oscillate, causing an exchange reaction to reach equilibrium and the halioysite an organically modifying agent, and then subjected to centrifugation at a centrifugal speed centrifugation 10min to 3000r/min, washed with deionized water the resulting organic halioysite 3-4 times, separated by suction after drying at 65 Ć, 200 - mesh sieve to obtain an organic-modified abrasive milled halioysite; Sustained-release pesticide preparation of composite halioysite (3): the desired pesticide dissolved in acetone was formulated as prodrugs of the mass concentration of 0.2-0.5 g/mL solution, the organic-modified halioysite 0.2g added to acetone solution was weighed, a thermostatic water bath at 25 Ć 150r/min speed oscillation of the oscillator to 3h such that the pesticide in the halioysite the adsorption of equilibrium is reached, after filtration with suction to 50 ml distilled water 3-4 times, sustained-release pesticide composite halioysite obtained dried to constant weight at room temperature.
