Problems solved by technology

[0003] The process of realizing the effect of sand surface in the related art has NCVM (Non-conductive VacuumMetallization; metal non-conductive vacuum coating) process; this process can realize the process of the effect of sand surface on the material of sand surface, and it cannot form the flashing surface of sand on the plane material Therefore, NCVM flashing sand topcoat has been further developed in related technologies. This topcoat realizes the effect of NCVM metal fineness and flashing sand, the crystals are closely arranged, the hand feels delicate, and the visual impact is strong. Make NCVM flashing sand surface effect; But the flashing sand surface effect of NCVM flashing sand finish paint in the related art is relatively poor

Abstract

The invention relates to NCVM finish paint as well as a preparation method and application thereof, and belongs to the technical field of paint. The finish paint is prepared from the following raw materials in parts by weight: 10 to 20 parts of thermoplastic acrylic resin, 10 to 20 parts of hexa-functional polyurethane acrylic resin, 10 to 20 parts of multifunctional reactive monomer, 1 to 5 parts of fluff powder, 3 to 5 parts of photoinitiator, 0.05 to 0.5 part of flatting agent, 20 to 30 parts of wax slurry and 20 to 30 parts of diluent. According to the NCVM finish paint capable of achieving the flash sand effect on the plane material, the problem that the flash sand effect can only be achieved on the sand surface material and cannot be achieved on the plane material in the NCVM technology in the related technology is solved, and the finish paint is excellent in vibration wear resistance.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an NCVM topcoat and a preparation method and application thereof. Background technique [0002] In daily life, mobile phones have become an indispensable communication tool for people. With the continuous updating and iteration of mobile phones, people have more and more diversified aesthetics on the appearance of mobile phones (for example, the appearance of mobile phones is required to have a sandy surface effect). [0003] In the related art, the process of realizing the sand surface effect is the NCVM (Non-conductive Vacuum Metallization; metal non-conductive vacuum coating) process; this process can realize the sand surface effect process on the sand surface material, and it cannot form a flash sand surface on the flat material. Therefore, the NCVM flash sand topcoat is further developed in the related technology, which realizes the NCVM fine metal and flash san...
