Abstract

The invention relates to an HF nano-film and further discloses a preparation method thereof. The HF nano-film is prepared from the following components in parts by weight: 50-70 parts of a perfluorosilane polymer, 33-46 parts of water, 5-8 parts of polycarbonate, 6-8 parts of methyl acrylate, 2-5 parts of epoxy-modified organic silicone resin, 1-3 parts of propylene carbonate, 2-5 parts of hydroxyethyl cellulose, 10-12 parts of a film-forming assistant, 2-3 parts of a cross-linking agent and 1-3 parts of a plasticizer. Each Si bond of glass is connected with a plurality of active fluorine bonds, on the basis that fluorine has multiple excellent characteristics of water and oil repellence, low friction, abrasion and corrosion resistance and the like, finally a 15-nanometer-thick ultrathin nano-coating with the functions of being ultrathin, easy to clean, resistant to abrasion, high in smoothness and the like is formed on a mobile phone screen; and operation is easy, the application range is wide, the quick effect is achieved, and the HF nano-film is non-combustible, safe and non-toxic.

Description

technical field [0001] The invention relates to the technical field of nano-membranes, in particular to an HF nano-membrane and a preparation method thereof. Background technique [0002] In 2008, with the rise of smart phones, resistive screens were widely used. The PET protective film effectively protects the screen and prevents the resistive screen from being over-extruded and scratched to cause failure. As mobile phones become thinner and lighter, screen strength increases, all kinds of ultra-high-definition picture shooting, Blu-ray video playback, and various mobile game experiences all indicate that consumers have higher requirements for mobile phone screen experience—— Thinner, lighter, cleaner and smoother. [0003] However, the existing mobile phone screens have the following defects: 1. The surface is easily stained with oil and cannot be cleaned cleanly; The screen of the mobile phone is not beautiful. Contents of the invention [0004] The purpose of the p...
