PVA-containing material for purifying air in vehicle and preparation technology thereof

Abstract

The invention relates to a PVA-containing material for purifying air in a vehicle and a preparation technology thereof. The method is characterized by comprising the following concrete steps: mixing active carbon granules, an antibacterial agent and a binder, wherein the weight of active carbon granules and antibacterial agent is 1-2% of the total weight and the weight of binder is 1-10% of the total weight; adding water and uniformly stirring, thereby acquiring a mixed solution; uniformly coating and rolling the acquired mixed solution onto a non-woven fabric surface; putting a coated non-woven fabric into an oven, drying for 3 hours and taking out, thereby acquiring an activated carbon non-woven fabric, wherein the temperature of the oven is 80 DEG C; and compounding the prepared activated carbon non-woven fabric with a polypropylene air filter cloth by adopting a thermal bonding technology, thereby acquiring an activated carbon filtration adsorbing material for purifying air in a vehicle. The material can effectively filter the pollutants, such as, PM2.5, methylbenzene and formaldehyde in a vehicle and prevent the pollutants from entering into the vehicle under the condition of guaranteeing the circulation between the air in the vehicle and the outside air, and meanwhile, can enhance the anti-microbial and mildew-proof functions.

Description

technical field [0001] The invention relates to a material for purifying air in a car containing PVA 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 carbons. Due to the...

Problems solved by technology

Because the activated carbon filter and adsorption material not only has a better effect of filtering tiny pollution particles in the air, but also can remove peculiar smell, it is a better air-conditioning filter material, so now the air-conditioning filter in the car generally contains activated carbon components , but 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 enable users to obtain more Comfortable environment in the car, thereby reducing nasal and lung diseases, and at the same time better protecting the air-conditioning system in the car
