In the automotive field, titanium dioxide powder is not only used as a pigment in car paints and coatings, but also plays a key role in protective coatings, glass coatings and plastic parts. In recent years, with the continuous improvement of consumers' requirements for automobile appearance, environmental protection and functionality, the application scope of titanium dioxide powder has continued to expand in the automobile field, showing a broad market prospect.

Application of Titanium Dioxide Powder in Automobile Coatings

In automobile coatings, tio2 powder is mainly used as a white pigment. Its high refractive index and hiding power give car paint excellent gloss, whiteness and color uniformity. The following are the main functions of titanium dioxide powder in automotive coatings:

Providing high hiding power and brightness: titanium dioxide powder can effectively improve the hiding power of car paint, making the appearance of the car more uniform and bright, especially suitable for white and metallic car paint. Because of its high refractive index, tio2 powder can reflect and scatter light, enhance the visual effect and make the vehicle more dazzling in the sun.

Enhance the weatherability: The automobile coating is exposed to the natural environment, which is easily affected by ultraviolet rays, rain and temperature changes and gradually fades or ages. Ti02 titanium dioxide has strong anti-ultraviolet ability, which can effectively block the ultraviolet radiation in the sun, prolong the service life of car paint and help the vehicle maintain its luster and color stability for a long time.

Improve the scratch resistance: the paint surface often faces the risk of scratching and rubbing. By adding ti02 powder, the hardness and durability of car paint can be improved to a certain extent, thus enhancing the scratch resistance of the surface and contributing to the long-term beauty of the car.

Titanium Dioxide Powder Can Be Used for Window Glass Coating

The application of titanium dioxide powder in window glass is mainly photocatalytic self-cleaning film and anti-ultraviolet protective film. Ti02 powder has photocatalysis and can decompose organic substances under illumination. This feature is widely used in the self-cleaning coating of automobile glass, which decomposes stains and dust through the film to keep the window clean after rain washing. In addition, titanium dioxide powder can effectively filter ultraviolet rays, reduce the fading and damage of articles in the car, and reduce the heat of sunlight entering the car, thus playing a certain role in heat insulation.

Titanium Dioxide Powder Can Be Used in Plastic and Rubber Parts

In modern cars, plastic and rubber materials are widely used in interior, bumper, rearview mirror and other parts. However, these materials will gradually age due to ultraviolet rays after being exposed to sunlight for a long time. As an anti-ultraviolet additive, ti02 titanium dioxide can delay the aging process of plastic and rubber parts and maintain their color, toughness and strength. In addition, the addition of tio2 powder can also improve the heat resistance and chemical corrosion resistance of plastic parts and enhance their stability in high temperature environment.

Antibacterial Coating of Titanium Dioxide Powder and Air Purification

The photocatalytic performance of titanium dioxide powder can not only be self-cleaning, but also have antibacterial and air purification functions. Coating a layer of titanium dioxide powder film on the interior of the car, especially on the air conditioning system and interior trim can effectively inhibit the growth of bacteria and mold, reduce the odor inside the car and improve the air quality inside the car. This feature is especially important for family owners with children and pets. The antibacterial property and air purification ability of titanium dioxide powder make it an ideal material for health and environmental protection, which is helpful to improve the interior environment of the car.

The application of titanium dioxide powder in automobile field is extensive and in-depth, which has brought remarkable performance improvement to automobile appearance, functional coating and air quality inside the automobile. With its excellent hiding power, photocatalytic self-cleaning ability and anti-ultraviolet performance, titanium dioxide powder has become an indispensable material in the automobile industry. With the development of environmental protection, functional coatings and smart cars, the application prospect of titanium dioxide powder in the automotive field is still broad.
