In the PET base film 1 of S1, the base film must have good transparency, no wrinkle, no scratch, and no dirt, so the incoming inspection must be careful not to affect the quality of the subsequent PET protective film due to the flaw of the base film.
Example 5
Referring to fig. 1-2, a color protection film includes a PET base film 1, a blue ink layer 2 is disposed on the top of the PET base film 1, an optical brightness enhancement film 3 is covered on the top of the blue ink layer 2, a glue layer 4 is disposed on the top of the optical brightness enhancement film 3, and a steel plate layer 5 is disposed on the top of the glue layer 4.
The bottom of the PET basic film 1 is connected with a heat insulation film 6, and the heat insulation film 6 is a heat insulation glass film.
The optical brightness enhancement film 3 is provided with a projection, and the optical brightness enhancement film 3 is a prism sheet or a light-gathering sheet.
The PET base film 1 adopts 0.05mm blue PET +0.02mm glue, and the blue ink layer 2 is blue ink with the thickness of about 3-5 mu m.
Through being equipped with optics brightness enhancement film 3 and thermal-insulated membrane 6 on PET basic membrane 1 respectively, when this protection film used on the light source, utilize optics brightness enhancement film 3 to make 2 colours on the blue printing ink layer brighter bright-colored, because the bottom of PET basic membrane 1 is equipped with thermal-insulated membrane 6, played fine thermal-insulated effect for PET basic membrane 1, avoid the heat conduction on the light source on PET basic membrane 1, lead to glue and the membrane on the PET basic membrane 1 to drop.
The processing method of the color protection film comprises the following processing steps:
s1, corona a surface layer of the prepared PET basic film 1;
s2, coating a layer of blue ink layer 2 with the thickness of about 4 microns on the corona surface of the PET film;
s3, putting the PET base film 1 coated with the blue ink layer 2 into an electric oven, and baking and curing;
s4, coating an optical brightness enhancement film 3 on the surface of the blue ink layer 2;
s5, sending the blue ink layer 2 coated with the optical brightness enhancement film 3 into an electric oven, and baking and curing;
s6, coating a glue layer 4SDK-48 on the surface of the optical brightness enhancement film 3;
s7, placing the optical brightness enhancement film 3 coated with the glue layer 4 into an electric oven, and baking and curing;
s8, attaching a layer of heat insulation film 6 to the bottom of the PET basic film 1;
s9, attaching a steel plate to the surface of the glue layer 4, and measuring the glue without residue;
s10, after numbering the protective film after ring measurement, sending the protective film into a curing chamber for curing.
In S1, the surface of the base material is corona treated to form reactive groups, so that a layer of fine pits is formed on the surface of the base material, and the adhesive force of the surface of the base material is improved.
The glue layer in S6 can closely contact with the surface of the adhered object and flow into the groove of the adhered surface as much as possible, so that the effective contact area is increased, the glue layer has higher anti-stripping capability, and the stripping speed is higher, and the stripping strength of the pressure-sensitive adhesive is higher.
In the PET base film 1 of S1, the base film must have good transparency, no wrinkle, no scratch, and no dirt, so the incoming inspection must be careful not to affect the quality of the subsequent PET protective film due to the flaw of the base film.
