Description

TECHNICAL FIELD

[0001] The present application relates to the field of automotive interior, in particular to a mosquito-repelling carpet surface for mosquito-repelling automotive carpet, and a preparation method and application thereof. BACKGROUND

[0002] With the continuous rise of global temperature, the population and quantity of mosquitoes are greatly improved, which increasingly threatens human health. In addition to direct biting and blood-sucking, mosquitoes also spread a variety of diseases. In China, there are four types of mosquito-borne diseases, including malaria, lymphatic filariasis, epidemic encephalitis B and dengue fever (or dengue hemorrhagic fever). In addition, mosquito-borne viral diseases also include yellow fever and various equine encephalitis, which are extremely harmful. As one of the four major pests, mosquitoes not only affect people's daily life, but also are the carriers of various diseases. For the car which has basically integrated into people's life as a means of transportation, mosquitoes entering the car pose a certain degree of threat to the health of the driver and passengers.

[0003] At present, the main methods for preventing and controlling mosquitoes are chemical control, biological control, environmental management, and comprehensive management combining these methods. Environmental management mainly plays a preventive role, and chemical control and biological control are the main means for controlling mosquitoes. Chemical control mainly has two forms, insecticides and repellents. Chemical mosquito repellents, such as mosquito incense and mosquito-killing aerosol, have irritability, and improper use can cause nervous system diseases, skin diseases, and even cancer with poor quality products, and also cause serious environmental pollution. Chemical repellent method is a technology that uses mosquito response to chemical signal substances to avoid them. Due to its high sensitivity and high selectivity, it has been widely used in chemical ecology.

[0004] Chinese patent CN103815761B discloses a preparation process of mosquito-repelling carpet, including color fixing, washing, vacuum water absorption, soaking, drying, inspection, packaging, and finished product. The composition of the mosquito repellent in the soaking solution includes 50% butyl diglycol, 10% chlorpyrifos, 20% aryl benzene polyoxydioxolane, and 20% water by volume fraction. By adding a mosquito repellent with a certain pH and a reinforcing agent Nano PU in the preparation process of the carpet, the mosquito repellent rate of the carpet is improved. However, the preparation process is complex, the cost is high, it is not suitable for use in cars, and the mosquito-repelling effect still needs to be further improved.

[0005] Therefore, it is of great significance to develop a mosquito-repelling carpet surface for mosquito-repelling automotive carpet with simple preparation process, low cost, and excellent mosquito-repelling effect, which is suitable for use in cars. SUMMARY
