Description
Technical Field
The invention relates to the technical field of mite-killing spraying agents, and particularly relates to a household mite-killing spraying agent and a preparation method thereof.
Background
Mites are widely distributed in dark corners of a room, carpets, mattresses, pillows, sofas, air conditioners, summer sleeping mats and the like, wherein the mattresses are most suitable for the growth and propagation of the mites. Allergic diseases caused by mites mainly comprise allergic rhinitis, allergic conjunctivitis, allergic asthma and allergic dermatitis, which can affect the daily work and life of patients, and even endanger life of serious patients. Generally, mites, mainly dust mites, which belong to arachnids, in a domestic environment were found to be allergic to house dust mites and dust mites in an allergen survey of 583 patients with allergic rhinitis in 72.6% and 68.8%, respectively. The method is more suitable for breeding dust mites in the environment with the annual average temperature of 20 ℃ and the humidity of more than 70 percent in south, so that the density of the mites in the cities in south and middle east of China is obviously higher than that in the cities in north.
Aiming at the characteristics of dust mites and the harm caused by the dust mites, the number of mite removing products on the market is correspondingly increased in recent years, besides a mite removing instrument adopting a physical method, various chemical mite removing products such as a mite removing bag, a mite removing laundry detergent and the like are sufficient, wherein pyrethroid insecticides can effectively remove mites, pyrethrins refer to pyrethroid medicines and are compounds simulating the synthesis of pyrethrins, and therefore the chemical components are generally ended by a 'pyrethroid' double letter. The dimethyl propane carboxylic ester is commonly called bifenthrin and also has good mite killing effect. However, pyrethrin has certain harm to human body, the harm is mainly reflected in stimulation to skin, eye, nose and throat mucous membrane, and even has some effect on human nerves in severe cases, so people can feel dizzy and uncomfortable.
In addition, there is a large group of products for alleviateing the plants to remove and repel mites. In fact, the essential oil and other components contained in many plants do have the function of expelling and even killing mites, but the content of the essential oil and other components is required to be high enough, and meanwhile, the essential oil components have volatility, and the mite expelling effect is greatly reduced along with the gradual reduction of the content after volatilization. Therefore, chemically synthesized active ingredients are still the mainstream in order to effectively and long-lasting acaricidal or even acaricidal action. Therefore, the search for products with stable properties, safety, high efficiency, low toxicity and rapid mite removal becomes a problem to be solved urgently.
Disclosure of Invention
The invention aims to overcome at least one defect of the prior art and provides a household mite-killing spray for solving the problem that the prior pyrethroid pesticide is harmful to human bodies when used for killing mites.

Therefore, the application of cinnamic acid and cinnamate in mite killing in the prior art is still limited. 3-phenylpropionic acid is a dihydro derivative of cinnamic acid, the ester of which is widely found in plants. However, the present inventors have conducted studies on 3-phenylpropionic acid, and have found that 3-phenylpropionic acid ester, which is a derivative of cinnamate, has a better mite-removing effect. Specifically, methyl 3-phenylpropionate is more effective. Therefore, on the basis, the inventor also adds the component C which is 3-aryl propionate and derivatives thereof, thereby further improving the mite removing effect of the mite removing spray. And has sufficient safety due to natural components. In addition, the compound has higher mite removing property than cinnamate or derivatives thereof, so that the compound can effectively reduce the dosage and further improve the safety, and is suitable for people including children.
