A kind of photocuring coating, ultraviolet light curing hydrophobic anti-adhesion film surface and preparation method thereof

Abstract

The invention provides a light-cured coating, an ultraviolet light-cured hydrophobic anti-adhesion film surface and a preparation method thereof. The light-cured coating comprises the following components in parts by weight: 15-30 parts of polyurethane acrylate, 10-30 parts of nano Particles, 2-4 parts of photoinitiator, 1-15 parts of perfluoropolyether, 5-15 parts of perfluoro-modified long-chain alkylsilane and 30-50 parts of solvent. The invention uses polyurethane acrylate, perfluoropolyether and perfluoromodified long-chain alkyl silane to compound nanoparticles, so that the photocurable coating is crosslinked through photocuring reaction to form a tight coating, which has wear resistance and forms a cured coating. The super-hydrophobic microstructure of the substance enhances its hydrophobicity. Through the microstructure formation and ultraviolet curing methods, a concave-convex microstructure is produced on the surface of the prepared film, which produces a lotus leaf effect, enhances hydrophobicity, and achieves superhydrophobicity. Production Afterwards, it can be rolled directly without the need for a protective film, saving costs.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a light-cured coating, an ultraviolet light-cured hydrophobic anti-adhesion film surface and a preparation method thereof. Background technique [0002] The development of human history and the progress of social civilization are largely based on the development of materials. Materials with excellent performance have promoted the development of human history and social progress. At the same time, the transformation of human history and the evolution of society also urgently need Material replacement. The development of materials usually has epoch-making significance in the history of human social development, and the emergence of new materials often serves as a sign of an era that reflects the development level of the current society. [0003] Inspired by nature, in the 1990s, a living organism in nature was used as a prototype, which was prepared by advanced technology ...

Problems solved by technology

[0005] However, the current light-curing coatings cannot achieve strong hydrophobicity, and most of their water contact angles can be between 110-120°, and most of the hydrophobic light-curing coatings used in the domestic market are in the coating film. Afterwards, a protective film is required to prevent the film from being adsorbed together when the film is rolled up, causing the customer to tear the film to generate static electricity to absorb dust and make the film surface dirty

Moreover, the current hydrophobic light-curing coatings are usually pasted with a silicon release film after coating. The silicon release film has the problem of silicon transfer. When the silicon is transferred to the hydrophobic surface, the water contact angle of the hydrophobic surface will decrease, resulting in a decrease in hydrophobicity.
