The composite acrylic transparent film is good in outdoor weather resistance, has molding property at high temperature and is capable of realizing higher transmittance under the condition of back polishing.
Description
Technical field
The utility model relates to a kind of film of pressure-sensitive adhesive coating; Particularly a kind of compound acrylic transparent membrane; This film can be used for making the metal appearance sign of various light-permeables, and this film is a kind of film with silver lustre effect that can be used for vacuum forming of tack.
Background technology
Many transparent membranes can present the silver lustre effect through back side Combined Processing.Select suitable thickness of coating, can realize excellent reflectance and light transmittance preferably; Select suitable film, excellent outdoor weathe resistance and good high-temperature plastic uptake performance can be provided.Such film goes for the application of three-dimensional plastic uptake back of the body polishing lamp box.The plastic uptake sign that adopts this silver lustre film to make has stainless texture daytime, and night under the situation that backlight is opened, demonstrate the color of light source.Laminated film in the market is of a great variety, compound PET is arranged, composite PVC; Compound BOPP or the like, there is following shortcoming in these existing films: outdoor weathe resistance is very poor, and composite bed is thicker; Translucent effect is relatively poor, and can not do the thermoforming processing of complicated three-dimensional.
The utility model content
The technical problem that the utility model will solve provides a kind of compound acrylic transparent membrane with silver lustre effect that can be used for vacuum forming of tack; The outdoor weathe resistance of this film is better; Have high temperature compacted under performance, can realize under the back of the body polishing situation than high-transmittance.
For solving the problems of the technologies described above, the utility model provides a kind of compound acrylic transparent membrane, and it from top to bottom comprises: transparent protective film, low viscosity can be moved quick glue, transparent acrylic film, metal deposition layer, high temperature resistant pressure sensitive adhesive, PET mould release membrance.
The thickness of said transparent protective film is 36～100 microns, and this transparent protective film can adopt PET, PP or PE material.
The thickness that said low viscosity can be moved quick glue is 5～10 microns, and peeling force is 5～10 gram/inches.
The thickness of said transparent acrylic film is 75～100 microns.
The thickness of said metal deposition layer be 150～450
The THICKNESS CONTROL of said high temperature resistant pressure sensitive adhesive is at 25 ± 5 microns; Said high temperature resistant pressure sensitive adhesive is an acrylate pressure sensitive adhesive.
The thickness of said PET mould release membrance is 36～100 microns.
Be provided with priming coat below the said metal deposition layer, the thickness of this priming coat is 1～2 micron, and the material that this priming coat adopts is the vinyl acetate-ethylene copolymer emulsion that contains carboxyl.
Compare with prior art, the compound acrylic transparent membrane of the utility model has following beneficial effect:
1. have excellent glossiness and reflectance, have the silver lustre effect;
2. have higher light transmission, the visible light light transmittance reaches 8～18%, depends on thickness of coating;
3. have good outdoor weathe resistance, the open air can reach the service life more than 7 years.
4. handle through thermoforming under the high temperature, can be processed into complicated 3 D stereo pattern or literal.
