Abstract
The present invention relates to an insect repellant and mothproof granule made up of nim tree leaves and a preparation method thereof. The insect repellant and mothproof granule is prepared from the fresh stem leaves of a nim tree which are dried and ground. The insect repellant and mothproof granule made up of nim tree leaves contains nim oil squeezed from nim nuts and a nim liquid extract extracted from nim nuts, uses natural menthol as a sublimation agent, uses beta-cyclodextrin to pack the nim oil and essence as a slow-release agent and an odorant and uses starch as a gluing plasticizer. The insect repellant and mothproof granule made up of nim tree leaves has the components by weight percentage of 75 to 80 % of nim tree powder, 5 to 6 % of starch, 3 to 2 % of liquid extract extracted from nim nuts, 2 to 3 % of nim oil, 3 to 2 % of natural menthol, 4 to 2 % of beta-cyclodextrin packing object and 8 to 5 % of water. The natural product with high quality and high efficiency provided by the present invention achieves the effect of inhibiting mildew and expelling moths with a method of keeping effective components escape for a long time by a slow-release technique. The green natural product has the advantages of environmental protection, simple and practical preparation method and low cost. The insect repellant and mothproof granule made up of nim tree leaves can gradually replace insect repellant agents of chemical components in the market.
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 indica A 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.
