Abstract
The invention discloses release aluminium foil and a preparation method thereof, and belongs to the field of printed wiring board. The release aluminium foil is composed of aluminium foil, an adhesive, PET thin film, and a release agent which are laminated successively. The release aluminium foil possesses certain adhesive force in peeling processes, is high in product quality, and can be widely used for flexible printed wiring board.
Description
Technical field
The present invention relates to printed wiring board field, particularly a kind of release aluminium foil and preparation method thereof.
Background technology
Its specification requirement of the remover of aluminium foil is: when peeling off, there is again certain adhesive force, and the key technology that remover technology is aluminium foil, the remover that traditional aluminium foil adopts is as follows:
Adopt silicone oil mould release, there is no adhesive force;
Adopt epoxy resin mould release, adhesive force is too strong;
The mould release that adopts silicone oil to be combined with epoxy resin, is difficult to solidify;
Adopt mould release membrance to be attached at aluminium foil, mould release membrance can remain on aluminium foil.
In sum, be necessary existing aluminium foil further to improve.
Summary of the invention
In order to solve the problem of prior art, the embodiment of the present invention provides a kind of release aluminium foil that has again certain adhesive force when peeling off and preparation method thereof.Described technical scheme is as follows:
On the one hand, provide a kind of release aluminium foil, described release aluminium foil is comprised of aluminium foil, adhesive, PET film, the mould release that stack arranges successively.
Particularly, described mould release is epoxy resin and celluosic resin synthetics, and parameter is 2.0 ± 0.8G/ ㎡.
Particularly, described adhesive is mephenesin Carbamate adhesive, and parameter is 2.0 ± 1.0 G/ ㎡.
Particularly, described aluminum foil thickness is 0.020mm ± 0.002mm; Described PET film thickness is 0.012mm.
On the other hand, provide a kind of release aluminum foil preparation, described release aluminum foil preparation comprises: S101, adhesive coating: S102, attaching; S103, coating release agent: S104, curing cooling; S105, packing: S106, sign.
Particularly, described step S101 specifically comprises: at aluminium foil one side adhesive coating.
Particularly, described step S102 specifically comprises: by adhesive, PET film is affixed in aluminium foil one side.
Particularly, described step S103 specifically comprises: mould release is coated on PET film.
Particularly, described step S105 specifically comprises: volume core: volume is grown into 1180mm, and wide is 1055mm, and internal diameter is 80mm, and thick is the aluminium core of 20mm; Vanning: use polyethylene foamed film to pack, then carry out bale packing with stainless steel dedicated box.
Particularly, described step S106 specifically comprises: on label, mark following content: the name of an article, very little method, lot number.
The beneficial effect that the technical scheme that the embodiment of the present invention provides is brought is:
When peeling off, have again certain adhesive force, product quality is high, can be widely used in flexible printed circuit board.
