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.

Embodiment 1

[0020] like figure 1 Shown, a kind of car ceiling that can release negative oxygen ion, comprises PU base material layer 1, non-woven fabric layer 2 and negative oxygen ion film layer 3. The PU substrate layer 1 is located at the bottom of the car roof; the non-woven fabric layer 2 is located between the PU substrate layer 1 and the negative oxygen ion film layer 3; the negative oxygen ion film layer 3 is located at the top of the car roof , in direct contact with the air, continuously releasing negative oxygen ions to the interior of the car.

[0021] Wherein, the PU substrate layer 1 is composed of PU board, glass fiber, adhesive and non-woven fabric, with a density of 900g / ㎡±90g / ㎡.

[0022] Wherein, the non-woven fabric layer 2 is made of non-woven fabric with a density of (230g±23) g / ㎡ and a thickness of 2mm; elongation at constant load: longitudinal 45%-90%; transverse 50%-110 %; weight reduction after heating ≤ 10g / ㎡; adhesion: unprocessed surface ≥ grade 4; processed ...

Abstract

The invention discloses an automobile roof capable of releasing negative oxygen ions, and belongs to the technical field of automobile parts, and the automobile roof comprises a PU(polyurethane)base material layer, a non-woven fabric layer and a negative oxygen ion film layer, the negative oxygen ion film layer is formed by spraying negative oxygen ion conversion liquid on the non-woven fabric layer and then air-drying the non-woven fabric layer. The PU base material layer is located on the bottommost layer of the automobile roof. The non-woven fabric layer is located between the PU base material layer and the negative oxygen ion film layer. The negative oxygen ion film layer 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. 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 oxygen ion 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...
