Abstract

The invention discloses the vegetable insecticide microcapsules and its preparation technology of a kind of clove oil synergy, it is an advantage of the present invention that using cornstarch as carrier adsorption clove oil, and included with beta cyclodextrin, the decentralization and load capacity of clove oil can not only be increased, and the water proofing property of material is improve, and the sterilized life-span of clove oil is extended, reach slow release effect, on the other hand, cornstarch also increases the degradation speed of the material, environment-friendly, is conducive to sustainable development.

Description

The vegetable insecticide microcapsules and its preparation technology of a kind of clove oil synergy
Technical field
The present invention relates to a kind of insecticide, and in particular to the vegetable insecticide microcapsules and its system of a kind of clove oil synergy Standby technique.
Background technology
Clove oil is refined by Myrtaceae Syzygium arbor cloves, with very strong antibacterial antioxidant effect, A kind of its official recognition that FDA has been obtained as food additives.Wherein topmost active material is eugenol（2- first Epoxide -4- (2- acrylic) phenol）, its content in clove oil accounts for 90-95%.Existing scholar proves that clove oil is gathered around Have than stronger oxidation resistances such as traditional chemical synthetized oxidation preventive agent BHA, BHT.Clove oil also has very effective The ability of breeding is suppressed growth of microorganism, has researcher that clove oil is added in edible film for suppressing harmful microorganism With the breeding of pathogen.Clove oil is used for the fresh-keeping of buffalo meat by Naveena etc., as a result finds to compare control group, experimental group Either smell or color and luster have and largely improve beef.
Ou Lijuan is in its master thesis《The preparation of chitosan-based active packing film and its fresh-keeping effect to beef grind Study carefully》In, it is prepared for a kind of sterilization fresh-keeping film using plants essential oil and shitosan, but the load capacity of its essential oil and decentralization, with And bactericidal effect all has much room for improvement.
The content of the invention
Think deeply based on more than, the present invention is intended to provide a kind of load clove oil, and with the desinsection of sustained release bactericidal effect Agent, and its preparation technology.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of vegetable insecticide microcapsules of clove oil synergy, it is characterised in that the preparation technology of the material includes following step Suddenly：
A. derris root, azedarach are placed in dryer and are dried, be dispersed in water after pulverizing, at 30-70 DEG C, water-bath 3- 4h, centrifugation, obtains supernatant liquor；
B. it is added in ethanol after cloves is shredded, under the conditions of magnetic agitation, flow back 2-3h, is cooled down after terminating, and filtering retains filter Liquid, obtains the ethanol solution of clove oil；
C. by the dissolving of chlopyrifos active compound in methyl alcohol, then mix with step a, b resulting solution, be stirring evenly and then adding into corn Starch, ultrasonic disperse is uniform, is made suspension, and 2-5h is vibrated in 20-40 DEG C of thermostatic control oscillator vibration, is used after vacuum filtration Distillation water washing 2-3 times, drying；
D. by beta-schardinger dextrin addition deionized water, stirring and dissolving adds step c gains, dodecyl sodium sulfate, profit Inclusion reaction 1-2h is carried out with ultrasonic method, then crystallisation by cooling, vacuum filtration, 20-40 DEG C of drying obtains insecticide microcapsules.
The vegetable insecticide microcapsules of described a kind of clove oil synergy, it is characterised in that used in preparation process Each raw material components and weight portion it is as follows：
Derris root 4-8, azedarach 5-10, cloves 15-20, ethanol 80-100, chlopyrifos active compound 3-6, methyl alcohol 30-50, corn form sediment Powder 10-15, beta-schardinger dextrin 25-35, dodecyl sodium sulfate 3-5；
The ethanol mass fraction is 90-98%.
The preparation method of the vegetable insecticide microcapsules of described a kind of clove oil synergy, it is characterised in that in step b The reflux temperature is 75-85 DEG C.
The preparation technology of the vegetable insecticide microcapsules of described a kind of clove oil synergy, it is characterised in that in step c The hunting speed of the thermostatic control oscillator vibration is 140-160r/min.
A kind of preparation technology of the vegetable insecticide microcapsules of described clove oil synergy, it is characterised in that step d institutes Ultrasonic method condition is stated for 20-40 DEG C, ultrasonic power 350-550W.
The beneficial effects of the invention are as follows：Using cornstarch as carrier adsorption clove oil and chlopyrifos active compound, and use Beta-schardinger dextrin is included, and can not only increase the decentralization and load capacity of clove oil, and improves the water proofing property of material, The sterilized life-span of clove oil is extended, slow release effect is reached, on the other hand, cornstarch also increases the degraded speed of the material Degree, it is environment-friendly, be conducive to sustainable development；The addition of clove oil, has the capsule and effectively suppresses growth of microorganism The ability of breeding, bactericidal property is excellent, and important synergistic effect can be played in chlopyrifos, reduces Pesticide use amount, reaches ring The purpose of guarantor；Derris root, the addition of Cortex Meliae extractive liquid can effectively prevent and treat lichee disease pest.
Specific embodiment
Specific embodiment of the invention is further described with reference to embodiment.
