Automobile roof capable of releasing negative oxygen ions

Abstract

The invention discloses an automobile roof capable of releasing negative oxygen ions, and belongs to the technical field of automobile parts. The automobile roof comprises a PU(polyurethane)base material layer, a PVC(polyvinyl chloride)fabric layer and a negative oxygen ion film layer, the PU base material layer and the PVC fabric layer are pressed by a wet mould pressing process, and the negativeoxygen ion film layer is formed by spraying negative oxygen ion conversion liquid on the PVC fabric layer and then air-drying. The PU base material layer is located on the bottommost layer of the automobile roof. The PVC fabric layer is composed of PVC, foaming and non-woven fabric and located between the PU base material layer and the negative oxygen ion film layer. The negative oxygen ion filmlayer is located on the uppermost layer of the automobile roof and makes direct contact with air, and negative oxygen ions are continuously released into an automobile. The negative oxygen ions released by the negative oxygen ion film layer can kill harmful substances such as bacteria, viruses and microorganisms, so that the environmental health of automotive trim is improved; the negative oxygenion film layer can adsorb active oxygen(oxygen free radicals)generated by pollutants, nitric oxide, cigarettes and the like originally coming from the atmosphere, harm of excessive active oxygen to the human body is reduced, and air is purified.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to an auto roof capable of releasing negative oxygen ions. Background technique [0002] The market demand for family cars in our country has caused many cars to enter the market directly after they leave the production line, and there is no release period for harmful gases and odors from various accessories and materials. At the same time, a variety of solvent-based adhesives are used for automotive interiors. During the use of adhesives, formaldehyde, benzene, toluene, xylene and other volatile organic compounds will be released, causing people to be poisoned unconsciously, and symptoms such as headaches and fatigue will gradually appear. . In severe cases, dermatitis, asthma, low immunity, and even leukopenia will occur! At the same time, due to the narrow space of the car, new cars have better airtightness, poor air circulation, and serious cross-contamination b...

Problems solved by technology

In severe cases, dermatitis, asthma, low immunity, and even leukopenia will occur! At the same time, due to the narrow space of the car, the airtightness of the new car is relatively good, the air circulation is not smooth, and the cross-pollution between the passengers in the car is serious, the harmful gas in the car is more harmful to the human body than the harmful gas in the house.
