Description

A kind of PET film for switch key

Technical field

It the utility model is related to PET film, and in particular to a kind of PET film for switch key.

Background technology

PET film is a kind of comprehensive packing film of performance comparision.Its transparency is good, glossy；With good airtight Property and fragrance protectiveness；Wire drawing PET film is mainly used in button, switch, home appliance panel, inscription plate moulding etc., with science and technology Development and the raising of people's aesthetic standards, decorative effect just have been to be concerned by more and more people, and wire drawing PET film is in PET film Surface forms long wire drawing texture, there is provided the unique novel decorative effect of panel, can be typically molded into again in wire-drawing surface printing-ink Type, but there is tensile strength deficiency in it, put the problem of sense of touch is not strong, and outward appearance is not novel enough.

Utility model content

In order to overcome the shortcomings of background technology, the utility model provides a kind of PET film for switch key, main solution Tensile strength of having determined deficiency problem, the PET film adhesive force that this is used for switch key is good, there is good tensile property, has knot Structure is simple, and cost is cheap, the advantages of novel appearance.

Technical scheme is used by the utility model：A kind of PET film for switch key, including key zone and side Edge area, described marginal zone are centered around key zone periphery, described key zone and marginal zone include frosted texture layer, dope layer, Adhesive-layer, PET basement membranes, water paint layer and electrostatic protection layer, described PET basement membranes upper surface are adhesive-layer, described viscose glue Layer upper surface is dope layer, and described dope layer upper surface is frosted texture layer, and described PET basement membranes lower surface is water paint Layer, described water paint layer lower surface are electrostatic protection layer, and the described key zone bottom is adsorbed film, described marginal zone The bottom is glue-line, and described frosted texture layer thickness is 3mm.

Further, described key zone is square.

Further, described key zone is circle.

Further, described frosted texture layer is the wire drawing texture layer handled by frosted.

Further, described water paint layer is acrylic copolymer dope layer, and its thickness is 1.5mm.

Further, described electrostatic protection layer is PE green electrostatic protection films, thickness 0.08mm.

Further, described PET basement membrane thicknesses are 0.125mm or 0.168mm or 0.255mm.

The beneficial effects of the utility model are：Due to taking above-mentioned technical proposal, the PET film that this is used for switch key is attached Put forth effort, there is good tensile property, have simple in construction, cost is cheap, the advantages of novel appearance.

Embodiment

The utility model embodiment is described further below in conjunction with the accompanying drawings.

As depicted in figs. 1 and 2, a kind of PET film for switch key, including key zone 1 and marginal zone 2, it is described Marginal zone 2 is centered around the periphery of key zone 1, and the shape of key zone 1 is identical with the shape of switch key, and key zone 1 and marginal zone 2 are one It is body formed；Described key zone 1 and marginal zone 2 include frosted texture layer 3, dope layer 4, adhesive-layer 5, PET basement membranes 6, water-based painting The bed of material 7 and electrostatic protection layer 8, the described upper surface of PET basement membranes 6 are adhesive-layer 5, and the described upper surface of adhesive-layer 5 is dope layer 4, the described upper surface of dope layer 4 is frosted texture layer 3, and the described lower surface of PET basement membranes 6 is water paint layer 7, described water The property lower surface of dope layer 7 is electrostatic protection layer 8, and the described bottom of key zone 1 is adsorbed film 9, the described bottom of marginal zone 2 For glue-line 10, the described thickness of frosted texture layer 3 is 3mm, and various patterns can be wherein sprayed on dope layer 4, improves PET film The novelty of outward appearance；Frosted texture layer 3 can improve point sense of touch when soft-touch control, can also increase coarse after cover film Degree, prevent switch surface excessively it is smooth it is bad touch by.

In the utility model, described key zone 1 is square；Described key zone 1 is circle；Described frosted texture Layer 3 is the wire drawing texture layer handled by frosted；Described water paint layer 7 is acrylic copolymer dope layer, and its thickness is 1.5mm.Water paint layer 7 is used to improve the adhesive force between PET basement membranes 6 and electrostatic protection layer 8, using water paint layer 7 So that PET film can meet that the wide-angle bending of moulding requires that drawing process floating coat is difficult for drop-off and not easy to crack, has Strong tensile resistance.

In the utility model, described electrostatic protection layer 8 is PE green electrostatic protection films, thickness 0.08mm；It is described The thickness of PET basement membranes 6 be 0.125mm or 0.168mm or 0.255mm.

This be used for switch key PET film adhesive force it is good, have good tensile property, have it is simple in construction, cost is low It is honest and clean, the advantages of novel appearance.

Every technical staff's notice：Although the utility model describes according to above-mentioned embodiment, this The invention thought of utility model is not limited to that utility model, any repacking with inventive concept, will all include this specially In sharp scope of patent protection.
