Abstract
The invention discloses a self-adhesive light-adjusting film. The self-adhesive light-adjusting film is composed of a self-adhesive layer and a light-adjusting film, and can be directly adhered to glass to use, in the process of power outage, the self-adhesive light-adjusting film is completely in a non-transparent state (similar to common ground glass), and in the process of power turn-on, the self-adhesive light-adjusting film quickly becomes clear and transparent. After any light-adjusting film is simply processed, a self-adhesive light-adjusting film can be achieved, and the self-adhesive light-adjusting film is remarkable in performance, convenient and practical, so that the application cost of the light-adjusting film is greatly reduced, and the application field of the light-adjusting film is broadened.
Description
Technical field
The invention belongs to film product processing and manufacturing field, particularly relate to a kind of self-adhering type light modulation film.
background technology
Light modulation film is a kind of novel electronics control light product, by the control of extra electric field, just can realize the Fast transforms of light modulation film between water white transparency and the opaque two states of milky.
Light modulation film has come out more than 20 year, due to early stage film to moisture-sensitive, so glass laminating just becomes the necessary salvo of practical application.Dimming glass also just becomes main application, dimming glass is special laminated glass, processing technology seems simple but very complicated, any procedure is grasped bad, dimming glass all will be caused to occur quality problems, dimming glass needs designed in advance and needs to make dimming glass before glass is installed in addition, can not be applied to the door and window of some maturations, this light modulation film is lacked very large a slice market.Current light modulation film cost is generally higher, adds and adds cost greatly again after making dimming glass, makes it be difficult to be widely used.
Along with the further lifting of light modulation film technology, light modulation film is no longer to moisture-sensitive, and very durable when protecting without doubling, uses so light modulation film directly can be pasted onto the enterprising enforcement of glass.
Most of light modulation film, without stickups such as shadow glue, ultra-violet curing glue, operate very complicated, and efficiency is lower on the market at present, and exploitation one is reliable and practical and lower-cost self-adhering type light modulation film is the task of top priority.
Summary of the invention
The object of the present invention is to provide a kind of self-adhering type light modulation film, this self-adhering type light modulation film is mainly made up of self-adhesive layer and light modulation film, can directly be pasted onto glass surface and realize dimming function, solve a series of difficult problems that current light modulation film pastes glass, easy for installation, as long as downstream user is guided according to operation and just can be installed, use field wide, any glass surface can be installed; This kind of self-adhering type light modulation film greatly reduces the application cost of light modulation film in addition, and has widened the application of light modulation film.
The present invention has two-layer structure, is self-adhesive layer and light modulation film successively.
Described self-adhesive layer has three-decker, acrylic glue-line successively, PET base material and layer of silica gel, the thickness of PET base material is 20-50 μm, and acrylic glue-line is coated on the one side of PET base material, and thickness is 10-30 μm, be 800 ~ 1500g/inch with the adhesive force in light modulation film PET face, layer of silica gel is coated on the another side of PET base material, and thickness is 10-30 μm, is 5 ~ 15g/inch with the adhesive force of glass.
Described self-adhesive layer produces in clean environment, and transmitance is 85 ~ 92%, the transmitance of self-adhesion light modulation film and the transmitance of light modulation film basically identical.
Described light modulation film can be any light modulation film, such as liquid crystal light modulation film, electrochromism light modulation film, black film etc.
This self-adhering type light modulation film adopts the mode of production of volume to volume overlay film, the acrylic glue-line of self-adhesive layer is overlayed on the arbitrary PET face of light modulation film.The PET face adhesive force of acrylic glue-line and light modulation film is comparatively large, can form an entirety, i.e. self-adhering type light modulation film.The adhesive force of layer of silica gel and glass surface is moderate, automatically can catch up with bubble removing, repeatedly can carry out pad pasting, and pastes closely with glass surface, makes light modulation film paste glass and becomes very simple, as long as glass surface is cleaned up i.e. Pasting.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention, and (1) is light modulation film, and (2) are self-adhesive layer.
Detailed description of the invention
Embodiment 1:
Step one: select a transmitance be 90% self-adhesive layer, the PET base material thickness of this self-adhesive layer is 30 μm; Acrylic bondline thickness is 20 μm, is 1000g/inth with PET face viscosity; Layer of silica gel thickness is 20 μm, is 7g/inth with the viscosity of glass surface;
Step 2: select a "on" position transmitance to be 80.5%, thickness is the liquid crystal light modulation film of 0.38mm;
Step 3: use volume to volume laminating machine, is overlying on the arbitrary PET face of light modulation film by the acrylic glue-line of self-adhesive layer;
Step 4: carry out electrode on same limit, carry out energising test, the transmitance of self-adhesion light modulation film is 80.3%.
