Material containing nanometer titanium dioxide and used for purifying air in vehicle and preparation technology thereof

Abstract

The invention relates to a material containing nanometer titanium dioxide and used for purifying air in a vehicle and a preparation technology thereof. The method is characterized by comprising the following steps: mixing a catalytic antibacterial agent nanometer titanium dioxide and a binder polytetrafluoroethylene PTFE and adding the mixture into an activated carbon host material; after mixing, adding ultrapure water at mass ratio of 5:1; adding water and then uniformly stirring, thereby acquiring a mixed solution; dipping the stirred mixed solution onto cellular activated carbon and skeleton non-woven fabrics at room temperature; and bonding the cellular activated carbon and the skeleton non-woven fabrics, rolling, pressing the surface moisture, rolling and then drying and forming, thereby acquiring a cellular activated carbon filtration adsorbing material. The dust and tiny particles in the outside polluted air are prevented from entering into the vehicle under the condition of guaranteeing the circulation between air in the vehicle and the outside air, so that the pollutants, such as, PM2.5, methylbenzene and formaldehyde, can be effectively filtered and prevented from entering the vehicle, and meanwhile, the anti-microbial and mildew-proof function can be enhanced.

Description

technical field [0001] The invention relates to a material for purifying air in a car containing nano-titanium dioxide and a preparation process thereof, belonging to the technical field of air purifying devices in a car. Background technique [0002] With the continuous development of my country's economy, automobiles have become an indispensable means of transportation for people's daily life. As the number of private cars in cities increases year by year, the air pollution on the road is becoming more and more serious. However, the space inside the car is small and the air circulation is poor, which is not conducive to the diffusion of pollutants and brings great harm to the health of car owners. How to improve the air quality in the car has become a topic of close concern to the majority of car owners. [0003] Activated carbon, also known as activated carbon black, is black powder or block, granular, honeycomb amorphous carbon, and there are also regular crystalline ca...

Problems solved by technology

Since the activated carbon filter adsorption material not only has a better effect of filtering PM particles in the air, but also can remove odors, it is a better air-conditioning filter material, so now the air-conditioning filter elements in general cars contain activated carbon components. However, there are almost no filter elements that can replace activated carbon components, which restricts the development of the air conditioner filter industry. Moreover, with the increasingly refined research on pollution, activated carbon filter adsorption materials urgently need to achieve better filtering effects to make users more comfortable. Improve the environment in the car, thereby reducing nasal and lung diseases, and at the same time better protect the air conditioning system in the car
