Abstract
An insect-repellent moth-eating resistant particle is prepared proportionally from nim tree powder, starch, fluid extract of nim seed, nim oil, natural menthol, beta-cyclodextrin and water.
Description
Affiliated technical field:
The present invention relates to hygienic biocide field, especially particularly a kind of direct insect repellant and mothproof granule made from seal chinaberry leaf and preparation method thereof with moth in the biospecific active substance repellent clothing.
Background technology:
Seal chinaberry (Azadirachta indicaA juss) is as the most potential pesticide plant of generally acknowledging in the world, and is remarkable with its applied range, insecticidal effect, bioactive substance content high and easily characteristics such as extractions be subjected to global generally attention.Joint research through the various countries scientist confirms: in the leaf and fruit of seal chinaberry, the material that contains a kind of mystery---nimbin, the biologically active that insect is had repellent, food refusal, inhibition growth and sterilization, and to human harmless with all warm blooded animals and natural enemy, natural degradation in environment, therefore, universally acknowledged seal chinaberry is classic pesticide plant.
The dress material insect-proof agent is essential in the clothing storage, relates to huge numbers of families.Crossing goes abroad uses naphthalene and camphor to be insect-proof agent for a long time, little because its insect protected is renderd a service, stimulates smelly greatly, the paracide insecticide that its market is just renderd a service by desinsection gradually captures.Yet paracide is organic chloride after all, and toxicity is bigger, easily accumulates in organism.Therefore, recently, in the existing trend of using and forbidding that limits of developed country.
The dress material insect-proof agent that China uses at present, though forbidden naphthalene, but still based on paracide and camphor ball, big to the human body excitant, it is smelly to distinguish the flavor of.Therefore, the development and production fragrant odour, anthelminthic effect is good, is again the seal chinaberry product of green natural environmental protection, must be subjected to wishing the modern society people's of back to nature welcome.And prior art adopts the nimbin adding assistant to make insecticide, perhaps is mixed to go up other plant and chemical composition is made insecticide, must accurately measure nimbin content in the raw material could prescription and determine dilution after usage amount.This will want to buy to buy and use expensive nimbin determining instrument and the critical extraction equipment of carbonic acid gas, its method complexity and Financial cost height.In order to overcome the deficiencies in the prior art, the invention discloses a kind of insect repellant and mothproof granule made from seal chinaberry leaf and preparation method thereof, is main component directly with the seal chinaberry leaf that is rich in nimbin, add neem oil and seal chinaberry liquid extract etc. and make end product.Need not highly purified nimbin, also need not accurately to measure nimbin content ability prescription in the raw material, the preparation method is simple, and is with low cost.
Summary of the invention:
The present invention realizes like this, utilization is made after containing the cauline leaf drying and crushing of seal chinaberry of active component of nim, wherein merge the neem oil that from seal chinaberry kernel, squeezes and extract the seal chinaberry liquid extract that makes, make sublimed agent with Natural menthol, connect neem oil and spices is made sustained release agent and odorant with the beta-schardinger dextrin-bag, and make bonding binder with starch.
This high-quality and efficient natural prodcuts provided by the invention make effective ingredient keep permanent method of overflowing with slow release method, reach mould fungus inhibition, the effect of repellent moth, and its Product Green natural environmental-protective, its preparation method is simple and easy to do, and is with low cost.The insect-proof agent that can progressively replace chemical analysis on the market.
Embodiment
One, the preparation of neem oil, seal chinaberry liquid extract
(1) from neem kernel, squeezes neem oil with cold-press;
(2) neem cake after will deoiling is pulverized, and makes with the method for solvent extraction nimbin and prints the chinaberry liquid extract.Organic solvent can comprise: ethanol, methyl alcohol, ether, acetone, n-hexane isopolarity organic solvent.
Two, the preparation of sustained release agent
Connect spices and neem oil formation beta-schardinger dextrin-inclusion compound with the beta-schardinger dextrin-bag.Utilize the special empty barrel structure of the molecule of cyclodextrine own, connect spices and neem oil with saturated solution method or solid bulk method bag.The sustained release agent of making in this way can keep for a long time fragrance keeping period and the volatilization phase of neem oil smell.
Three, the preparation of leaf powder
After the fresh cauline leaf drying with the seal chinaberry, pulverize with cracker, it is standby to cross 40-60 purpose dusting cover.
Four, the preparation of finished product
(1) will print chinaberry leaf powder, starch and solid each component continuous stirring to evenly mixing.
(2) neem oil is diluted with 60 ℃ hydro-thermal method with an amount of 95% ethanol, will print liquid components such as chinaberry liquid extract, essence, water again and add mixing.
(3) with the liquid components even spraying to solid constituent, be mixed into strongly evenly.
(4),, obtain sheet or granular product at 60-70 ℃ temperature compacted under by mould and forcing press.
(5) use the cylinder drying drying, the time is 15-20 minute, and temperature is 60-70 ℃.
(6) pack with the good nonwoven of permeability.
Several embodiments of the present invention are described below, but content of the present invention is not limited to this fully.
