On, bonding binder used can overflow in sub-box, and sub-box has the function of accommodating glue, meanwhile, in the EVA adhesive film
Side wall is also reserved with spew groove, and when EVA adhesive film and glass are bonded, extra glue can overflow to spew groove, effectively anti-
Only extra glue is solidified in glass side, ensure that the neat sense of glass side.
The utility model is further arranged to: being bonded with transparent polyimide film between the cable compartment and PET film layer
Layer.
By using above-mentioned technical proposal, transparent polyimide film layer is bonded between cable compartment and PET film layer, thoroughly
Bright polyimide film has the advantages that lighting, ultrathin, flexibility, also has excellent heat-resistant stability, and bonding is overflowed
Glue can be filled in cable compartment, prevent glue is excessive from overflowing from the EVA adhesive film surrounding side wall.
The utility model is further arranged to: the EVA film and cable compartment, cable compartment and transparent polyimide film
It is connected between layer, transparent polyimide film layer and PET film layer by aqueous polyurethane adhesive layer.
By using above-mentioned technical proposal, aqueous polyurethane adhesive layer is colourless, transparent, and very thin thickness can be realized preferably
The mobility of cementation, aqueous polyurethane adhesive layer is smaller, and glue is not easy to overflow.
The utility model is further arranged to: the lateral wall of the PET film layer is adsorbed with low density polyethylene layer.
By using above-mentioned technical proposal, low density polyethylene layer have good translucidus, also have excellent waterproof,
Moisture resistance and excellent tensile strength and tensile elongation facilitate after low density polyethylene layer is adsorbed on PET film layer
Improve the structural strength of PET film layer.
The utility model is further arranged to: being folded with Electrostatic Absorption between the PET film layer and low density polyethylene layer
Film.
By using above-mentioned technical proposal, using Electrostatic Absorption film by low density polyethylene layer and PET film layer secure bond,
Facilitate the use of reduction glue amount, while the thickness of the explosion-proof film can also be reduced；Electrostatic Absorption film has excellent adsorptivity
It can be, it can be achieved that low density polyethylene layer be quickly adhered on PET film layer.
The utility model is further arranged to: the low density polyethylene layer trypsin method has titanium dioxide optical catalyst painting
Film.
By using above-mentioned technical proposal, titanium dioxide optical catalyst film encounters sunlight or fluorescent lamp, ultraviolet light shine
After penetrating, can make under the excited state of ambient light the organic matter adhered in glass surface layer, pollutant become carbon dioxide and water and
It is automatic to eliminate, to realize stable self-cleaning function.
The utility model is further arranged to: being sealed in the spew groove by silicone glass cement.
By using above-mentioned technical proposal, after EVA adhesive film molding, internal each structure sheaf connection extra glue used
It can be spilled over in spew groove, spew groove is filled using silicone glass cement again, guarantee the planarization of laminated glass side.
In conclusion the advantageous effects of the utility model are as follows:
