Abstract

The invention discloses a microcapsule preparation for coating solid pesticide raw drug and a preparation method of the microcapsule preparation, and specifically relates to the technical field of pesticide preparations. The microcapsule preparation comprises capsule skin and a capsule core, wherein the capsule core is encapsulated inside the capsule skin; the capsule skin is composed of any one or two of animal and plant gum, urea formaldehyde gum, melamine formaldehyde resin, isocyanate and polyamine; the capsule core comprises at least one active component of solid pesticide and one or moresurfactants. The microcapsule pesticide preparation inhibits the decomposition and loss of pesticides by light, heat, air, water, microorganisms and other chemical substances in the environment, andimproves the stability of the pesticide. At the same time, the capsule skin can reduce the volatility of pesticides, conceal the original odor, reduce contact toxicity, inhalation toxicity and drug harm, and relieve the irritation to human beings and animals and the toxicity to fish.

Description

technical field [0001] The invention relates to the technical field of pesticide preparations, more specifically, the invention relates to a microcapsule preparation coated with a solid pesticide original drug and a preparation method thereof. Background technique [0002] Microcapsule technology is to use polymer materials to wrap the solid pesticide effective body from the outside, and use the lattice gap of the molecular capsule wall to release it slowly, avoiding photolysis, volatile oxidation, acid-base neutralization reaction degradation, etc., thereby reducing the original The amount of medicine used, prolong the duration of effect. And with people's awareness of safety, environment, and ecological sustainable development, microencapsulation technology has been paid more attention in the field of pesticides. [0003] However, the existing pesticide formulations cannot artificially control their persistence period and release rate, and the stability of the pesticide f...
