Abstract

An internal combustion type electrically heated insect repellent in the form of tablet is prepared from allethrin, tetramethrin, propargylthrin, piperonyl butoxide, diesel oil, starch, fatty acid, oxidant, talc powder and modified starch through proportional mixing and die pressing.

Description

Internal burning type electrically heated insect repellent piece

Technical field:

The present invention relates to a kind of internal burning type electrically heated insect repellent piece, belong to the electric mosquito repellent tablet class.

Background technology:

Traditional electric mosquito repellent tablet adopts raw paper sheet or cotton fibre soaks in soup or moisten the back with medicine liquid droplet dries and makes; Can imagine, the effective ingredient molecule (medicine) of this moment is directly exposed to be centered around around carrier (raw paper sheet or the cotton fibre) molecule, in a few hours of bringing into use, more volatile drug molecule is overflowed easily, but because traditional electric mosquito repellent tablet promotes unique power of medicine molecule effusion is the temperature of electric heater, therefore, and after through 4-5 hour, its volatilization temperature of drug molecule that remains in the anti-mosquito incense sheet will be higher than the temperature that electric heater can provide, and just again can't overflow.The weak point of Here it is traditional electric mosquito repellent tablet.

Summary of the invention:

The objective of the invention is to, at the present situation of prior art, provide a kind of effective composition is wrapped in the middle of one deck colloid molecule, it is long to have lasting drug effect, kills mosquito class effect height, and the expelling parasite sheet of new generation of environmental protection.

The composition of internal burning type electrically heated insect repellent piece of the present invention is, 0～3% cinerins medicine, comprise allethrin, the Es-bioallethrin, the S-bioallethrin, bioallethrin, d_allethrin etc., 0～3% tetramethrin (or dtetramethrin), 6～0% the alkynes third chrysanthemum ester (or its derived product), 1～6% Butacide (PBO), 6～1% diesel oil, 10～40% starch, 7～2% fatty acid, 28～3% oxidant is (as potassium chlorate, sodium chlorate, potassium nitrate, sodium nitrate, potassium permanganate etc.), 30～12% talcum powder, 12～30% modified starch.After the even mixing of above-mentioned constituent, adopt the powder pressing method to make.

This internal burning type electrically heated insect repellent piece compared with prior art, it is obvious to kill mosquito class effect, duration of efficacy is long, two province Disease Control and Prevention Centers are detected through the Jiangsu and Zhejiang Provinces, duration of efficacy reached more than 16 hours, discharged evenly, detected through Jiangsu Province Disease Control and Prevention Center, its toxicity is little poison level, and drug effect meets country's " indoor harmacological effect evaluation of agriculture chemical registration hygienic insecticide " B grade standard.

The function of above-mentioned each component is as follows:

1, the cinerins medicine comprises two kinds of allethrin, Es-bioallethrin, S-bioallethrin, bioallethrin, d_allethrin and tetramethrin and the alkynes third chrysanthemum esters: as host, insect is driven and kills.

2, Butacide (PBO):, the host drug effect is had humidification as the synergist of host.

3, diesel oil: make anti-blushing agent and use, prevent that tablet from making moist in air.

4, starch: make fuel and use, under heater temperature and special catalytic action, oxidation reaction slowly takes place, and emit heat.

5, fatty acid: make thermal conducting agent and use, at a certain temperature, fat becomes liquid when dirty by solid, and is up again after being heated, thereby make the heat transmission even.

6, oxidant: it can produce the oxidation reaction of heating, and can continuously go on.

7, talcum powder: make cooling agent and use, it can control reaction temperature and speed, and it is slowly carried out.

8, modified starch such as acid starch are made colloid and are used, and with its packaging medicine molecule, make its slow effusion.

Preparation method of the present invention is after each component is evenly mixed, to adopt the powder compaction forming method to make.

This formula combination detects through Jiangsu Province Disease Control and Prevention Center, and its toxicity is little poison level.Drug effect meets country's " indoor harmacological effect evaluation of agriculture chemical registration hygienic insecticide " B grade standard.
