Nanomaterials are widely used in automotive coatings in China

Nanomaterials are widely used in automotive coatings in China:


1. Stone resistant paint


    The most close to the ground parts of the car body, often by a variety of splashes of rubble, rubble impact, the best use of protective coatings with stone impact effect; Paint with low coefficient of friction should be used in car window guide slots and other frequently worn parts.


    Adding nano AL2O3, nano SiO2 and so on can improve the surface strength of the coating, improve the wear resistance and reduce the impact damage of gravel and debris.


2. Anti-static paint


    The development and application of antistatic coatings for automotive interior decoration and plastic parts are becoming more and more extensive because of the troubles caused by static electricity.


    Composite of nano materials such as SiO2 at 80nm, TiO2 at 40nm and Cr2O3 at 20nm with resin can be used as electrostatic shielding coating on automobiles. In addition, nano-oxide Fe3O4, TiO2 and ZnO can also be used to make anti-static coatings of various colors.


Deodorant paint


    There are often odors in new cars that come from volatile substances in resin additives used in car upholstery. In addition, the odor of cigarettes and sweat inside the car is absorbed by the surface such as seats and siding.


    Nanomaterials have strong antibacterial and deodorizing functions and adsorption capacity, so using some nanoparticles as carriers, adsorption of antibacterial ions, made of deodorizing coatings for automobile interior decoration and other surfaces can achieve the purpose of sterilization and antibacterial. Nanometer ZnO particles have superior antibacterial, disinfection and deodorization functions, so it can be used as a functional assistant to finish natural fibers and obtain antibacterial fibers with good performance, which can be used for automobile interior textile and curtain textile, etc., and can absorb odor and purify air.


conclusion


    The application of nanometer materials in automobile will be more and more widely, but due to the price problem of nanomaterials, the interface between the particle/media properties, theoretical problems such as surface activity, dispersion of nanometer materials and particles into the medium technology is not very perfect, so to achieve industrial application in the field of automotive industry is still exist certain difficulties. We believe that with the continuous progress of science and technology, all kinds of problems in application will eventually be solved step by step. Using the special properties of nanomaterials, the development and preparation of automotive coatings with excellent properties have broad development prospects.
