What are the advantages of nano anti-fingerprint oil?
Due to the characteristics of nanostructures, nano-atoms are introduced into the resin, so that the nano-containing resin has special functions different from other resins, such as low surface self-sufficiency, outstanding weather resistance, stain resistance and the like, and the refined nano-nano Anti-fingerprint oil anti-fouling can be superior to weather resistance, salt spray resistance, oleophobic and hydrophobic, easy to clean and other functions.
It can be used to indicate the size of the interaction between the appearance of the polymer and other substances. Generally, the apparent energy of organic matter is 11~80mJ/m2, while the polymer containing nano-base side chain has low surface self-energy, generally between 11~30mJ/m2. The low-surface-free nano-containing resin makes it difficult to wet the surface, and has the characteristics of water-repellent oil. Therefore, the nano-anti-fingerprint oil prepared by using the nano-resin has poor adhesion function and strong anti-pollution.
The nano-tree anti-fingerprint oil has excellent durability and weather resistance, and the nano-resin has excellent physical function, low melting point, good processing function and good coating quality. Nano anti-fingerprint oil is the most widely used, such as Kynar500 of Atofina Company of America and Hylar5000 of Ausinont Company of Italy, all of which are produced and products of PVDF. Compared with nano-resin nano-anti-fingerprint oil and acrylic resin, polyester, silicone and modified products, nano-containing resin nano anti-fingerprint oil provides longer-term maintenance and decoration for the substrate, coated with PVDF resin. For example, weather resistance is compared with acrylic resin, polyester, and silicone resin. In the study of appearance, the nano-anti-fingerprint oil prepared on the basis of PVDF is still natural exposure for 10 years or longer, regardless of the accelerated aging test, and no significant chemical changes have occurred in the coating film.
For the nanometer anti-fingerprint oil, the salt-tolerant function of nano-acrylic resin is reported in foreign literature. For example, the room temperature boring nanometer-containing anti-fingerprint oil produced by Asahi Glass Co., Ltd. can reach 3000H without foaming or Dropped. The nano-anti-fingerprint oil reported in China can achieve no change in the 500H paint film; the nano-coating of the aircraft skin has no change after 2500H.
In general, the stain resistance of organic coatings is mainly related to the appearance of the coating, the appearance of the coating, and the like. Therefore, reducing the touch area of the pollution source and the coating layer is advantageous for the anti-adhesion effect and self-cleaning of the coating layer; and by increasing the touch angle of the pollution source and the coating layer (also reducing the surface self-energy), improving the appearance of the surface. Sexuality can provide an excellent anti-adhesion effect, which affects the adhesion of the coating to the source of contamination. In nano-resin nano-anti-fingerprint oil, the nano-electron-negative nano-substitutes replace the orientation of hydrogen, which greatly reduces the surface energy. The electrons are tightly adsorbed around the nano-nucleus, which is not easy to polarize and shields the nucleus; The radius of the nano-atoms is small, and the polarization of the CF bond is small. The combined effect of the two atoms makes the internal structure of the molecules fine, showing extraordinary stain resistance, water repellent, oil-repellent and other special appearance functions. Antifouling effect.
Taking nano anti-fingerprint oil made of nanometer as an example, compared with silicone-containing resin, polyester, water-based acrylic resin and solvent-based acrylic resin, the staining conditions are trace amount (816), trace amount (810), and trace. The amount (810), the fineness (715), and the fineness (615), it can be seen that the nano-anti-fingerprint oil made of nano-anti-fingerprint oil is the best.
