Description

Silver Fruit Microcapsule Suspending Agent And Its Preparation Method

(1) technical field:

The present invention relates to the formulation technical field of agricultural chemicals, is a kind of Silver Fruit Microcapsule Suspending Agent And Its Preparation Method specifically.

(2) background technology:

The bionic plant source bactericide is that the disinfection structure formula that proposes liquid with ginkgo is a template die, the bionic plant source bactericide of synthetic, its low toxicity is efficient, noresidue, do not injure the bactericide that natural enemy is nuisanceless first-selection, but this medicine stink is too big, and packing material is decomposed stimulates seriously corroded, packs the polyester bottle at present, the plastic bottle that all types of plastic is made all holds stimulation that can't stand it, the packing difficulty.

(3) summary of the invention:

Purpose of the present invention is intended to overcome the deficiency of above-mentioned prior art, and a kind of silver fruit microcapsules suspension emulsion is provided.

Another object of the present invention provides the preparation method of silver fruit microcapsules suspension emulsion.

The present invention has mainly solved the problem that bionic plant source bactericide stink is big, corrosion is packed.

Silver fruit microcapsules suspension emulsion of the present invention since its capsule skin forms by natural high molecular polymer fully, can complete cracking in air, to plant itself and environmental nonpollution, can on pollution-free food, use.

In order to achieve the above object, the present invention is achieved in that silver fruit microcapsules suspension emulsion, its special character is that it is really is effective ingredient with silver, and contain surfactant, vegetable oil, auxiliary agent, solvent, water, also contain the composition of in animal glue, natural plant gum and the marine product glue two kinds and two or more hydrolysate simultaneously.

Silver fruit microcapsules suspension emulsion of the present invention, its described surfactant is triphen ethyl phenol APEO, dibenzyl xenol APEO; Its described vegetable oil is cottonseed oil, rapeseed oil, castor oil acid; Described auxiliary agent is calcium dodecyl benzene sulfonate, phenethyl phenol polyethenoxy polyethenoxy ether, castor oil ethylene oxide adduct; Described solvent is a dimethylbenzene; Described animal glue is gelatin; Described natural plant gum is an amylan; Described marine product glue is fish glue, sodium alginate.

The preparation method of silver fruit microcapsules suspension emulsion of the present invention comprises following processing step:

A, the making of capsule nuclear in silver fruit crude oil, adds auxiliary agent, vegetable oil, surfactant, adds solvent again and dilutes, and is heated to 60-80 ℃, constantly stirs simultaneously, adds a certain amount of water again;

B, the making of capsule skin is carried out all kinds of glue respectively earlier with two or more the glue in animal glue, natural plant gum, the marine product glue and is separated, and is heated to 60-80 ℃ respectively, filters the back and mixes, and stirring gets final product;

C, microcapsule formulation is poured the capsule skin raw material of step b in the reactor of capsule nuclear of step a, mixes under 300-600 rev/min rotating speed and stirs, and after lowering the temperature 2 hours naturally simultaneously, packs.

The preparation method of silver fruit microcapsules suspension emulsion of the present invention, after its described capsule skin manufacturing process steps adopts the hydrolysate of animal glue and natural plant gum to mix, its capsule hole skin is little and inhomogeneous, does not reach the release time of regulation on request, therefore also need add blowing agent.

Silver fruit microcapsules suspension emulsion of the present invention is with organic macromolecule the effective body of agricultural chemicals to be wrapped from the outside, utilize the big lattice voids of ascus wall of dividing to discharge lentamente, avoid volatilization, oxidation, corrosion packing etc., thereby greatly reduce former medicine usage amount, prolong the lasting period, its lasting period and rate of release can artificially be controlled.

Compared with the prior art Silver Fruit Microcapsule Suspending Agent And Its Preparation Method of the present invention has substantive distinguishing features and marked improvement: 1, silver fruit microcapsules suspension emulsion stink obviously alleviates; 2, silver fruit microcapsules suspension emulsion has alleviated the corrosivity to packing greatly; 8, the drug effect of silver fruit microcapsules suspension emulsion improves 1.5 times than the drug effect of bionic plant source bactericide, prolongs effective drug duration more than l5 days.
