Abstract
The utility model discloses an aluminum foil polyester film composite structure, comprising a polyester film layer, an aluminum foil layer, an adhesion layer and a release paper layer which are connected sequentially. The length of one end of the polyester film layer and the length of one end of the aluminum foil layer are shorter than the length of one end of the release paper layer, insulation film layers are covered on edges of shorter ends of the polyester film layer and the aluminum foil layer and two sides thereof, one end of each insulation film layer completely covers the edge of one end of the aluminum foil layer and is adhered onto the release paper layer via the adhesion layer, the other end of each insulation film layer is covered on the polyester film layer so that the edge of one end of the aluminum foil layer can not expose, thereby preventing aluminum foil from contacting with parts on a main board of a liquid crystal display to cause short circuit. The aluminum foil polyester film composite structure further adopts double faced adhesive tapes as the adhesion layer, is simple in structure, easy in manufacturing, simple in adhesion and not easy to cause short circuit of the parts on the main board of the liquid crystal display, reduces manufacturing cost, increases production efficiency and is applicable to popularization and use.
Description
Technical field the utility model relates to a kind of aluminium foil polyester film composite construction.
Background technology can produce electromagnetic radiation when working owing to the components and parts on the LCD mainboard, and electromagnetic radiation may produce other electrical equipment and disturb, and electromagnetic radiation also may impact and damage human body.In order to reduce the electromagnetic radiation of LCD mainboard, common way be main circuit board in LCD and iron pan or main circuit board and panel metal edges along between stick one deck aluminium foil polyester thin film tape, be used for electromagnetic radiation shielding, but the aluminium foil at common aluminium foil polyester thin film tape edge exposes easily, and the aluminium foil that exposes conducts electricity easily.When adopting common aluminium foil polyester thin film tape to attach, because of LCD mainboard space limited, its sticking position is difficult to accurate control, as long as the position that attaches has deviation slightly, will make the aluminium foil at aluminium foil polyester thin film tape edge touch other part on the LCD mainboard, cause part short circuit on the LCD mainboard easily, cause LCD main board failure or damage, serious also might cause fire.
Summary of the invention the utility model purpose provides a kind of low cost of manufacture, attaches simply and be difficult for causing the aluminium foil polyester film composite construction of part short circuit on the LCD mainboard.
For achieving the above object, the utility model adopts following scheme to realize: the utility model comprises laminated polyester film and the aluminium foil layer that links to each other successively, tack coat and off-style paper layer, one end length of its laminated polyester film and aluminium foil layer is shorter than the length of off-style paper layer one end, on end margin of short laminated polyester film of described length and aluminium foil layer and two side areas thereof, cover insulating thin layer, be that an end of described insulating thin layer covers an end margin of aluminium foil layer fully and is bonded on the described off-style paper layer through described tack coat, the other end of described insulating thin layer is covered on the described laminated polyester film, and an end margin of described aluminium foil layer can not exposed; Said structure is avoided aluminium foil to touch part on the LCD mainboard and is caused short circuit.
Being provided with second tack coat between described insulating thin layer and the laminated polyester film covers described insulating thin layer on laminated polyester film.
The end edge of described off-style paper layer slightly exceeds described insulating thin layer and tack coat end edge, tears release liners when being convenient to bond, and convenient the attaching operated.
Described insulation film layer material is a polyester film.
Described second bonding layer material is a double faced adhesive tape.
The beneficial effects of the utility model are: the utility model covers insulating thin layer on end margin of short laminated polyester film of described length and aluminium foil layer and two side areas thereof; Insulating thin layer one end covers the aluminium foil layer edge fully can not expose an end margin of aluminium foil layer, avoids aluminium foil to touch part on the LCD mainboard and causes short circuit; The utility model also adopts double faced adhesive tape as tack coat, its simple structure, easy to manufacture; It attaches and is difficult for causing part short circuit on the LCD mainboard simply again; The utility model has reduced manufacturing cost, production efficiency is provided, and is suitable for promoting the use of.
Description of drawings now is further elaborated the utility model in conjunction with the accompanying drawings:
Fig. 1 is a generalized section of the present utility model;
Fig. 2 is the schematic top plan view of the utility model Fig. 1.
Embodiment as shown in Figures 1 and 2, the utility model comprises laminated polyester film 1 and the aluminium foil layer 2 that links to each other successively, tack coat 3 and off-style paper layer 4, one end length of its laminated polyester film 1 and aluminium foil layer 2 is shorter than the length of off-style paper layer 4 one ends, on end margin 21 of short laminated polyester film 1 of described length and aluminium foil layer 2 and two side areas thereof, cover insulating thin layer 5, be that an end 51 of insulating thin layer 5 covers an end margin 21 of aluminium foil layer 2 fully and is bonded on the off-style paper layer 4 through tack coat 3, the other end 52 of insulating thin layer 5 is covered on the laminated polyester film 1, and an end margin 21 of aluminium foil layer 2 can not exposed.
Being provided with second tack coat 6 between insulating thin layer 5 and the laminated polyester film 1 covers insulating thin layer 5 on laminated polyester film 1.
The end edge 41 of off-style paper layer 4 slightly exceeds described insulating thin layer 5 and tack coat 3 end edge.
Insulating thin layer 5 materials are polyester film.
Second tack coat, 3 materials are double faced adhesive tape.
