Description

Mosquito-repellent incense

Technical field

The present invention relates to mosquito-repellent incense technical field, especially a kind of mosquito-repellent incense.

Background technology

Mosquito is a kind of worldwide sanitary insect pest, its all one's life through ovum, larva (wriggler), pupa, four periods of adult.Mosquito is importantly that it is one of communication media of infectious disease.According to the study, the disease of mosquitoes spread reaches more than kind more than 80.In the whole world, 1,200,000 people are about had to infect filariosis.The disease of the mosquito meeting infectious disease toxicity of major part kind, comprises yellow fever, dengue fever, Japanese encephalitis, St. Louis encephalitis, polyarthirtis, Rift Valley fever (RiftValleyfever), contract elder brother Gen Yare and West Nile fever.On earth, then do not have which kind of animal to have larger harm than mosquito to the mankind.Mosquito serious threat human health, only drives these disgusting mosquitoes, could control epidemic infectious diseases, could ensure human health as can be seen here, improves the quality of life of people.

For many years, people develop and employ a large amount of hygienic insecticide products, are used for killing mosquitoes.Mosquito-repellent incense is the most ancient natural drug mosquito repellent way.Just the culicifuge incense rod that Chinese medicine is made is there is period as far back as the Southern Song Dynasty.Containing active ingredient in modern mosquito-repellent incense is pyrethrins, and it has the effect of mosquito.After burning mosquito incense, pyrethrins in mosquito-repellent incense evaporates along with smog, send out in the air of indoor, make the neural paralysis of mosquito, so mosquito or bornly to get killed, or four loosely run away, thus the effect playing mosquito killer current mosquito-repellent incense production industry insecticidal active ingredient, the mainly pyrethrin such as cypermethrin, Prallethrin, allethrin, ES Esbiothrin, the nerve can benumbing mosquito causes that it is dead.Addition in mosquito-repellent incense is about 0.2% ~ 0.4%.Having this kind of mosquito-repellent incense can cause in use long process, people's is uncomfortable, may bring out the diseases such as asthma, also can cause environmental pollution simultaneously.

Summary of the invention

Problem solved by the invention is to provide the mosquito-repellent incense of a kind of use safety, non-moisture-sensitive.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:

It comprises the raw material of following weight portion:

Sweet wormwood residue powder 200-300 part, ramulus mori bar powder 100-200 part, wormwood 20-50 part, charcoal powder 40-60 part, nano zine oxide 40-60 part, carboxymethyl starch 40-60 part, Lavender 5-10 part.

In technique scheme, scheme can also be more specifically: described sweet wormwood residue powder, for sweet wormwood residue is dry, then pulverized, sieved through 100-120 order, decontamination and obtaining; Described ramulus mori bar powder, for ramulus mori bar is dried rear pulverizing, is crossed 100 mesh sieves and obtains; The particle size range of described nano zine oxide is 80 ~ 120 nanometers, specific surface area be 51.5 squares of faces/gram.

Further, its parts by weight of raw materials is as follows:

200 parts, sweet wormwood residue powder, 200 parts, ramulus mori bar powder, wormwood 50 parts, charcoal powder 60 parts, nano zine oxide 50 parts, carboxymethyl starch 40 parts, Lavender 5 parts.

Further, its parts by weight of raw materials is as follows:

300 parts, sweet wormwood residue powder, 100 parts, ramulus mori bar powder, wormwood 20 parts, charcoal powder 40 parts, nano zine oxide 60 parts, carboxymethyl starch 60 parts, Lavender 7 parts.

Further, its parts by weight of raw materials is as follows:

250 parts, sweet wormwood residue powder, 150 parts, ramulus mori bar powder, wormwood 40 parts, charcoal powder 50 parts, nano zine oxide 40 parts, carboxymethyl starch 50 parts, Lavender 10 parts.

The said sweet wormwood of the present invention is the dry aerial parts of China traditional medicine sagebruss artemisia annua, formal name used at school artemisia annua, has clearing away summerheat, sterilization, desinsection, cuts the effects such as cruel, and its principle active component is antimalarial artemisinin and volatilization wet goods.Content of artemisinin in sweet wormwood about about 1.0%, industrial abstract rate about 90%, therefore, for the enterprise of qinghaosu annual production 50 tons, nearly 6000 tons of sweet wormwood residue, also keeps away mosquito effective component containing abundant in residue.

The present invention, compared with existing mosquito-repellent incense, has following beneficial effect:

1, the mosquito-repellent incense that the present invention is is base-material with sweet wormwood residue powder and ramulus mori bar powder, its raw material composition is not only exquisite, and because adding wormwood and Lavender, have a significant effect in mosquito repellent etc., and the present invention makes full use of sweet wormwood residue powder and ramulus mori bar powder is primary raw material, achieves resource and uses.

2, the present invention is owing to being added with nano zine oxide, it has the specific surface area of super large, there is very strong water absorbing capacity and long lasting quality, moisture pinning can not affected anti-mosquito incense sheet to make moist, the easy moisture absorption causes sagging weakness owing to using charcoal powder to overcome conventional mosquito coil, ignition difficulties, the crisp and deficiencies such as frangibility of finished product.

3, sufficient combustion of the present invention, smog is little, smell delicate fragrance, little to the excitant of human body, has the special-effect of Chinese herbal medicine, belongs to environmental type product.
