Technical Field

The invention relates to the technical field of building materials, in particular to a multi-layer rubber carpet for repelling mosquitoes and a preparation method thereof.

Background

With the improvement of the education system, indoor playgrounds are built in colleges and universities, and physical exercises can be conveniently performed on rainy days. However, a serious problem in the use process of the indoor sports ground is the biting of mosquitoes, and particularly, in the afternoon of summer each year, the number of mosquitoes is large, so that the experience and enjoyment of people in the indoor sports process are seriously influenced. As the global temperature is continuously raised, the population and the quantity of mosquitoes are greatly improved, the health of human beings is increasingly threatened, the mosquitoes can not only directly sting and suck blood and harass, but also more seriously transmit various diseases, the mosquito-borne diseases in China comprise four types of malaria, lymphofilariasis, epidemic encephalitis B and dengue fever (or dengue hemorrhagic fever), the more important virus diseases of mosquito-borne diseases comprise yellow fever, various equine encephalitis and the like, and the harm is extremely large.

At present, chemical insecticides are mostly used in mosquito control modes of indoor sports grounds, but single chemical insecticides are used for a long time, so that mosquitoes generate insecticide resistance, the environment is seriously polluted, the human health is threatened, and at present, a lot of insecticides are in spray form and can be sprayed on food if being careless, and poisoning can happen if being eaten by mistake; in addition, the physical light induction lamp and other methods have the problems of high cost, inconvenience in use and the like. The chemical evasion method is a technology for evading chemical signal substances by utilizing the reaction of mosquitoes, and has wider and wider application range in chemical ecology due to high sensitivity and high selectivity.

The carpet for the indoor playground is made of rubber as a main raw material, and the odor emitted by the rubber has an attraction effect on mosquitoes, so the population and the quantity of the mosquitoes in the indoor rubber playground are higher, but the chemical insecticide is usually used to cause the drug resistance of the mosquitoes to be greatly increased, and the environment and the population are harmed when the chemical insecticide is used in a large dose.

Therefore, how to improve the raw materials and the preparation process of the rubber carpet, and develop a green and harmless rubber carpet with a significant mosquito repelling effect is a problem to be solved by those skilled in the art.

Disclosure of Invention

In view of the above, the present invention aims to provide a multi-layer rubber carpet for mosquito repelling and a preparation method thereof.

In order to achieve the purpose, the invention adopts the following technical scheme:

a multi-layer rubber carpet for repelling mosquitoes comprising: the rubber layer is connected with the base cloth layer through the bonding layer;

the rubber layer is formed by injection molding of polypropylene, rubber and a mosquito repellent agent in a weight ratio of (80-100) to (80-120) to (1-5);

the mosquito repellent agent is prepared by mixing the following raw materials in parts by weight: 8-12 parts of star anise, 8-12 parts of wrinkled gianthyssop herb, 5-8 parts of camphor, 5-8 parts of mint, 3-5 parts of mozzie buster, 3-5 parts of marigold and 3-5 parts of pyrethrum.

The invention is based on the traditional Chinese medicine, refers to the pharmacological research of modern Chinese traditional medicine, and fully exerts the synergistic effect of each component by screening and repeatedly verifying the traditional Chinese medicine, wherein the effect brief introduction of each raw material is as follows:

fructus Anisi Stellati, fruit of fructus Anisi Stellati of Magnoliaceae, also called fructus Anisi Stellati, has strong fragrance, can be used as spice and flavoring agent for medicinal use, has strong fragrance, and has effects of expelling parasite, warming middle warmer, regulating qi-flowing, invigorating stomach, relieving vomit, dispelling cold, and exciting nerve;

agastache rugosus is the overground part of Pogostemon rugosus or Pogostemon rugosus of Labiatae, has fragrant smell, can help Zhongzhou to clear qi, expel dampness and avoid dirt, and has the effects of expelling parasites, eliminating dampness and activating spleen, avoiding dirt and regulating the middle warmer;

the camphor is a granular substance prepared by distilling and refining roots, stems, branches and leaves of cinnamomum camphora belonging to cinnamomum of Lauraceae, and has the effects of dredging orifices, benefiting qi stagnation, removing dirt, killing parasites, relieving itching, reducing swelling and relieving pain;

the mint has special fragrant fragrance, mosquitoes and insects can vertigo, and the mint has the effects of cooling, diminishing inflammation and relieving itching;

the mozzie buster has volatile fragrance, can extract geranium oil, has the main components of geraniol, rhodinol, citronellol, linalool and the like, and has the effect of repelling mosquitoes;

marigold has certain smell of flushing nose, is afraid of mosquito and is a special excellent natural insect repellent;

pyrethrum, flower contains avermectin, and can be used for treating mosquito poisoning.
