Detailed Description
The following examples are provided to illustrate the features of the present utility model and other related features in further detail to facilitate understanding by those skilled in the art:
as shown in FIG. 1, the anti-static self-adhesive dimming film comprises a dimming film body, wherein the dimming film body comprises a hardening anti-static coating 1, a first substrate layer 2, a first conductive layer 3, a PDLC layer 4, a second conductive layer 5, a second substrate layer 6, a double-sided adhesive layer 7 and a release film layer 8 which are sequentially laminated, and the hardness of the hardening anti-static coating is more than or equal to 3H. In a specific implementation, the hardened antistatic coating 1 is formed by coating a layer of hardened antistatic coating on the first substrate layer 2 through a coating process and curing.
The first conductive layer 3 and the second conductive layer 5 are ITO plating layers.
As described above, the utility model provides an anti-static self-adhesive dimming film, which can effectively solve the problem of serious dust adsorption on the surface of the self-adhesive dimming film and can reduce the cleaning frequency by coating the hardened anti-static coating 1 on the surface of the first substrate layer 2. As the common rag is made of cotton soft plant fiber and polyester fiber and has the hardness below 1H, the hardness of the self-adhesive dimming film can be improved by selecting the hardening antistatic coating 1 with the hardness more than or equal to 3H, so that scratches can not be left on the surface of the dimming film when the cleaning rag is used for cleaning, the self-adhesive dimming film has good scraping prevention and protection effects, and can be applied to scenes with more dust such as subway tunnels.
In practice, the hardened antistatic coating 1 is mainly composed of a hardened resin doped with a conductive material/semiconductor material. Namely, the main components are conductive/semiconductive and resin: common semiconductor materials include nano oxide indium tin oxide and the like, and common conductive materials are high-molecular conductive polymers and the like; the resin is mainly acrylic acid modified resin. In this way, the hardened antistatic coating 1 can have good antistatic properties and high hardness.
The hardened antistatic coating 1 is colorless and transparent. In this way, so as to cooperate with the first substrate layer 2, it is ensured that the PET light transmittance after the application of the hardened antistatic coating 1 is reduced by not more than 1%.
The thickness of the hardening antistatic coating 1 is 0.1-10 micrometers, and the refractive index is 1.3% -1.5%. In specific implementation, the thickness can reach 0.1-10 micrometers through a coating process. In this way, the refractive index matching and thickness design of the hardened antistatic coating 1 are facilitated, so that the effects of reducing the reflectivity and improving the transmissivity can be further realized.
The first substrate layer 2 and the second substrate layer 6 are PET base films. Thus, it is convenient to have high permeability, low haze, high brightness, and the like.
In actual production, the anti-static self-adhesive dimming film can be prepared by adopting the following two preparation modes:
mode one:
the preparation method comprises the steps of coating a hardening antistatic coating on the non-coating surface of the rolled PET base film in a micro-concave coating mode, and then preparing the self-adhesive dustproof dimming film through a coating process.
Mode two:
after the common self-adhesive dimming film is installed, a layer of hardening antistatic material is coated in a spraying mode.
As described above, the scheme protects the anti-static self-adhesive dimming film, and all technical schemes which are the same as or similar to the scheme are shown to fall into the protection scope of the scheme.
