Embodiment Construction

[0012] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0013] An anti-oil stain self-cleaning polycarbonate film of the present invention has a thickness of 1-12 μm and has a base material 2 on which a layer of self-cleaning coating film 1 is covered. The base material 2 is poly Carbonate film or sheet.

[0014] Self-cleaning coatings have the technical advantages of high light transmittance, nanoscale, and single effective crystal form. According to the principle of lotus leaves, they are made of nanostructure materials. The extremely low surface tension of nanomaterials makes them have strong hydrophobic and oil-resistant abilities; The contact area between dust and polycarbonate film or sheet surface is reduced by 90%, and it has incomparably superior self-cleaning properties. Water rolls off the surface of polycarbonate film or sheet like lotus leaves without leaving water marks, which can effectively ...

Abstract

The invention relates to an oil-pollution-prevention self-cleaning polycarbonate membrane and a preparation method thereof. The oil-pollution-prevention self-cleaning polycarbonate membrane is characterized in that the thickness of the membrane is 1-12 mu m, the membrane is provided with a substrate, the substrate is coated with a self-cleaning coating, and the substrate is a polycarbonate membrane or sheet. The preparation method provided by the invention comprises the following steps: coating fluorocarbon nano-coatings on a high-transparency polycarbonate film or sheet by using a rotary coating method, wherein the fluorocarbon nano-coatings are used for forming the self-cleaning coating; and processing the high-transparency polycarbonate film or sheet for about 60 minutes at a temperature of about 100 DEG C. The oil-pollution-prevention self-cleaning polycarbonate membrane is simple in structure, and can achieve the effects of pollution prevention, grease prevention and self cleaning, therefore, the membrane can be widely applied to the fields of safety glasses, protective masks, membrane switches, dashboards, touch screens, liquid crystal display panels, and the like.

Description

Technical field: [0001] The invention relates to an anti-oil stain self-cleaning polycarbonate film and a preparation method thereof. Background technique: [0002] Polycarbonate film has good comprehensive properties. Ordinary films are colorless and transparent, and the light transmittance is above 90%. The film not only has excellent electrical properties, but also has high tensile strength and rigidity. Its impact resistance is also relatively high among thermoplastics. High. Polycarbonate film has low water absorption rate and product molding shrinkage rate, and excellent creep resistance, so the size of the product is stable under different temperature and humidity conditions. It is suitable for making precision components, especially its excellent cold resistance and heat resistance. It can work for a long time in a wide range of 100℃~130℃. [0003] Because polycarbonate film is transparent, non-toxic, tasteless, and odorless, it has good fragrance retention and can...
