Abstract

The present invention relates to fly killing incense and its preparation process. The fly killing incense contains natural pyrethrins as effective component in 0.2-6 wt%, tert-butyl phenol matter, such as BHT, as stabilizer in the amount of 0.5-10 times that of pyrethrins, fuel medium, adhesive, fire retardant, etc. and is prepared through mixing, forming, stoving and other steps. It has stable volatilizing, lasting effect and high fly killing effect, and has comfortable smell, no harmful matter, no toxic residue and high safety.

Description

A kind of flies killing incense and preparation method thereof

Technical field

This product relates to the hygienic biocide goods, particularly contains the fly eradication incense coil of plant extracts.

Background technology

At present, the medicine poisoning class hygienic biocide product that China is commonly used, the overwhelming majority uses the insecticide of organic synthesis as insecticidal active ingredient, comprises organic phosphates, carbamates and pyrethroids, at present based on the lower pyrethroid of toxicity.But these chemical substances are in desinsection, not only the smell of insecticide itself makes us unhappy, importantly they cause certain negative effect to human body and environment inevitably, there is tangible chronic toxicity in particularly long-term contact, and is especially remarkable to the negative effect of pregnant woman and infant development generation.Also be that so the use of synthesis of pyrethrin ester class in recent years accounts for more than 60% in the incense coil goods; But external relevant this insecticides also takes place in succession to the report of the serious chronic toxicity of human body generation; And a big weakness of this insecticides is that insect very easily develops immunity to drugs to it.It is to use the Chinese herbal medicine desinsection that minority is also arranged in the incense coil goods, and for example application number is 01142669.1 and 01114657.5 disclosed content.Chinese herbal medicine based article complicated component, raw material is difficult for obtaining, and production cost is higher, so be subjected to bigger restriction.

Summary of the invention

The purpose of this invention is to provide a kind of safe, natural insect killing substance pyrethrins replaces the insecticide of chemosynthesis efficiently, with the usefulness that improves the effective drug product with to human body and environmentAL safety.

Natural pyrethrin (pyrethrins) is the active insecticidal components that extracts from pesticide plant Dalmatian chrysanthemum (Pyrethrumcinerariaefolium Trey).Natural pyrethrin has following outstanding characteristic:

1, knock down with the speed of kill insects fast;

2, resolve into the oxidation of inert matter, particularly sunlight and air under the natural conditions easily, make pyrethrins can resolve into water and carbonic acid gas fully at short notice, do not produce any noxious material;

3, almost harmless to people and warm blooded animal, and do not find chronic toxicity so far to the people, promptly do not have carcinogenesis, can not bring out sudden change, to reproduction and yet not influence of development of fetus.

4, the long-term use can not cause the insect resistance problem yet.

5, natural pyrethrin process evolution of long period of time process is good with the blending of environment.

The present invention utilizes the natural pyrethrin insecticidal power strong, and characteristics almost non-toxic, free from environmental pollution, as effective desinsection of flies killing incense at composition.Because the pyrethrins poor stability needs to add suitable antioxidative stabilizer in the manufacturing process, could guarantee that it plays consistently desinsection and renders a service.

After deliberation, DI-tert-butylphenol compounds is that antioxidant has desirable antioxidant effect to natural pyrethrin; Through a large amount of evidences, when the pyrethrins effective content is 0.2-6%, add 0.5-10 doubly to the BHT of pyrethrins, just can effectively improve its stability, reach desirable effect.The amount of pyrethrins is lower than at 0.2% o'clock, and then killing effect is undesirable, even a part of down and out fly has the phenomenon of recovery.DI-tert-butylphenol compounds is that stabilizing agent adopts BHT (2, the 6-BHT) usually.

The preparation of pyrethrum flies killing incense can be used dry pyrethrum flower powder 20-30 part, extraction ground-slag 20-30 part and carbon dust 10-15 part with the burning base-material, and fire retardant is used starch 4-6 part with talcum powder 22-30 part, adhesive.The content of pyrethrins is about 1.0-1.5% in the pulvis flores pyrethri, and the content of extraction in the ground-slag is about 0.1%, also will add pyrethrum ester oil 3-20 part of 10-20% in addition, makes that final content reaches 0.2-6% in the incense coil.The present invention can be made into different shapes such as incense coil, post perfume (or spice).

Preparation method's step of pyrethrum flies killing incense of the present invention is as follows: the base-material that will burn, adhesive, fire retardant mix in proportion, add low amounts of water, stir and mix, and use mould compression moulding, oven dry.With an amount of pyrethrum ester oil with evenly be sprayed on the fragrant base air-dry getting final product after stabilizing agent mixes.

The present invention compares with existing similar technology, has following outstanding advantage:

1, with natural pyrethrin as insect killing substance, the safety of human body is improved greatly, comprise that development of fetus is not had influence yet; Non-residual toxicity in environment.

2, when sootiness, produce the little odor type smell of chrysanthemum, do not stimulate human body, do not make us unhappy sensation yet.

3, fly and mosquito are all had well extremely except that effect.

The present invention uses the natural materials desinsection, has outstanding safety and to the innocuousness of environment, is the novel product in the effective drug class.And abundant in the source of Yunnan Province Dalmatian chrysanthemum, production cost is low.
