nano-topcoat
automobile topcoat is an intuitive evaluation of automobile quality, which not only determines the beauty of the automobile, but also directly affects the market competitiveness of the automobile. Therefore, in addition to high decoration, automotive topcoat also requires excellent durability, including resistance to ultraviolet rays, moisture, chemicals and acid rain erosion and scratch resistance.
nano-coating can meet the above requirements. Nano-particles are dispersed in the framework of organic polymers, which act as load-bearing fillers and interact with the framework materials, which is helpful to improve the toughness and other mechanical properties of the materials. The results show that% nano-O2 particles can be completely dispersed in the resin, which can improve its mechanical properties, especially its scratch resistance, and has a good appearance, which is beneficial to the manufacture of automotive topcoat coatings. Adding modified nano-3 into polyurethane varnish coating with mass fraction% can improve the gloss, leveling, flexibility and coating hardness of varnish coating. Nano-O2 is a kind of anti-ultraviolet radiation material, and its tiny particles have large specific surface area, which can quickly form a network structure when the coating is dried, and can simultaneously enhance the strength, smoothness and aging resistance of the coating. Using nano kaolin as filler, polymethyl methacrylate nanocomposites are not only transparent, but also absorb ultraviolet rays, and can also improve thermal stability, which is suitable for manufacturing automotive topcoat coatings.
In addition, nano-materials also have the effect of changing color with the angle. As a rising star, the pigment with the effect of changing color with the angle is one of the most important and promising application fields in the application of nano-materials. For example, adding nano-O2 into metallic shiny topcoats such as automobiles and cars can make the coatings produce rich and unpredictable color effects. When nano-powder is used in coating system together with flashing aluminum powder or mica pearlescent pigment, it can reflect blue opalescent light in the side light area of the coating, thus increasing the fullness of the color of metal topcoat and producing a unique visual effect.
Nano-glass coating
Using the strong ultraviolet reflection characteristics of nano-powder materials, nano-O2 powder is added to the coating in a certain proportion, which can effectively shield ultraviolet rays and protect passengers from ultraviolet radiation. When it is coated on the surface of the window glass, it can also decompose the dirt deposited on the glass, oxidize harmful gases and kill bacteria in the air under the action of ultraviolet rays, and has the functions of antifouling, dustproof, scratch-resistant, wear-resistant, fireproof, purifying the interior environment of the car and ensuring the health of passengers.
collision color-changing paint
collision color-changing paint is used to prevent hidden dangers caused by automobile collision, and it contains micro capsules with dyes in them. Once the car shell coated with this collision color-changing coating is subjected to strong external force such as collision, the capsule will rupture and release dye, so that the color of the impacted part will change immediately or become a designated color to remind people to pay attention to it.
At present, the paint on the car shell will not change color when it is hit, but its appearance will change slightly, so its internal trauma is not easy to find and will leave future trouble. After using the collision color-changing paint, the damaged parts can be repaired according to the color-changing situation to eliminate hidden dangers.
Anti-stone-impact coating
The part of the car body closest to the ground is often impacted by all kinds of splashed gravel and rubble, so it is best to use protective coating with anti-stone-impact effect; Paint with low friction coefficient should be used in the parts with frequent friction and wear, such as car window guide groove.
Adding nano-2O _ 3 and nano-O _ 2 into automobile coatings can improve the surface strength, wear resistance and reduce the impact damage of gravel and rubble.
anti-static coatings
Because of the trouble caused by static electricity, the development and application of anti-static coatings for automobile interior decoration and plastic parts are increasingly extensive.
Nano-materials, such as O2, O2 and 2O3, can be used as electrostatic shielding coatings for automobiles. In addition, nano-oxides 3O4, O2, O, etc. can also be used to make multi-color antistatic coatings.
deodorizing coatings
often have peculiar smell in new cars, which comes from volatile substances contained in resin additives in automobile interior decoration materials. In addition, it is difficult to remove the smell of cigarettes and sweat in the car after being absorbed by the surfaces such as seats and siding.
Nano-materials have strong antibacterial and deodorizing functions and adsorption capacity. Therefore, some nano-particles are used as carriers to adsorb antibacterial ions, and deodorizing coatings can be made for automobile interior and other surfaces to achieve sterilization and antibacterial purposes. Nano-O particles have excellent antibacterial, disinfection and deodorizing functions, so it can be used as a functional assistant to finish natural fibers to obtain antibacterial fibers with good performance, which can be used in automotive interior textiles, curtains and other textiles to absorb odor and purify the air.
