Abstract
The utility model discloses a PE (poly ethylene) protective film with steady attachment performance, which comprises a PE substrate layer on the lower surface of the protective film, a mucilage glue layer is arranged on the upper surface of the protective film, a chemical treatment layer is arranged between the PE substrate layer and the mucilage glue layer which is a mixture layer of curing agent and oily polypropylene glue, and the chemical treatment layer is a mixture layer of chromic acid and alcohol. The PE protective film with steady attachment performance comprises the mucilage glue layer, the chemical treatment layer, and the PE substrate layer, the mucilage glue layer is added with the curing agent, therefore, through controlling the thickness of the mucilage glue layer, and guaranteeing the adhesive strength of the mucilage glue layer to be between 300-500g, the PE protective film can be steadily attached on rough surface and does not have adhesive residue when being torn off, and the film does not crack.
Description
Technical field
The utility model relates to electronic product surface and attaches the protective membrane technical field, particularly a kind ofly attaches firm PE protective membrane.
Background technology
For the shell that makes the products such as notebook computer, panel computer, smart mobile phone avoids being subject to scratching or scuffing in the process of transportation, preservation; usually attach in its surface protective membrane; and the shell of some products is more coarse; it is firm that the protective membrane of the disclosed viscosity of prior art below 300g is difficult to attach thereon, and tear and the glue phenomenon often occurs falling.
In addition, the viscosity of protective membrane is stronger, the phenomenon of just easier generation protective membrane fracture when tearing.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of firm PE protective membrane that attaches, and by add solidifying agent and control adhesive-layer thickness in adhesive-layer, it is firm to be able to attach at uneven surface, and tears without the purpose of cull.
For achieving the above object, the technical solution of the utility model is as follows:
A kind ofly attach firm PE protective membrane; comprise the PE substrate layer that is positioned at the protective membrane lower surface; described protective membrane upper surface is compounded with adhesive-layer; be provided with the chemical treatment layer between described PE substrate layer and the described adhesive-layer; described adhesive-layer is the mixture layer of solidifying agent and oiliness polypropylene glue, and described chemical treatment layer is the mixture layer of chromic acid and ethanol.
Preferably, described PE substrate layer thickness is 0.08mm.
Preferably, described adhesive-layer thickness is 0.01mm.
Preferably, described chemical treatment layer thickness is 0.001mm.
Pass through technique scheme; the utility model provides a kind ofly attaches firm PE protective membrane; comprise adhesive-layer, chemical treatment layer, and the PE substrate layer, the main body of adhesive-layer is oiliness polypropylene glue; wherein also added solidifying agent; and in coating process, adopted cable roll metering coating method, by the thickness of accurate control adhesive-layer, guaranteed that its adhesive power is between 300-500g; it is firm to have realized also attaching at uneven surface, and tears without the purpose of cull.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art.
Fig. 1 is the disclosed a kind of firm PE protective membrane cross-sectional schematic that attaches of the utility model embodiment.
The represented corresponding component title of numeral among the figure:
1, PE substrate layer 2, adhesive-layer 3, chemical treatment layer
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
According to Fig. 1; the utility model provides a kind of firm PE protective membrane that attaches; comprise and be positioned at the PE substrate layer 1 that protective membrane lower surface thickness is 0.08mm; be compounded in that thickness is the adhesive-layer 2 of 0.01mm on the protective membrane upper surface; and be arranged on that thickness is the chemical treatment layer 3 of 0.001mm between PE substrate layer 1 and the adhesive-layer 2; wherein; adhesive-layer 2 is mixture layers of solidifying agent and oiliness polypropylene glue; chemical treatment layer 3 can be the mixture layer of chromic acid and ethanol, also can be the mixture layer of nitric acid, sulfuric acid and ethanol.
The utility model provides a kind ofly attaches firm PE protective membrane, comprise adhesive-layer 2, chemical treatment layer 3, with PE substrate layer 1, process with the surface of 3 pairs of PE substrate layer 1 of chemical treatment layer first in the 2 front meetings of coating adhesive-layer, make it produce one deck minute aperture, thereby increase the contact area of PE substrate layer 1 and adhesive-layer 2, and then can promote the base adhesion force between PE substrate layer 1 and the adhesive-layer 2, occur the cull phenomenon when avoiding tearing protective membrane; The main body of adhesive-layer 2 is oiliness polypropylene glue, in order to improve the glue chain effect of adhesive-layer 2, has wherein also added solidifying agent; Coating adhesive-layer 2 is to adopt cable roll metering coating method, can accurately control the thickness of adhesive-layer 2, guarantees its adhesive power between 300-500g, and it is firm to have realized also attaching at uneven surface, and tears without the purpose of cull.
In addition, the thickness of PE substrate layer 1 has been increased to 0.08mm, can not occur the phenomenon of protective membrane fracture when tearing protective membrane.
To disclosed a kind of above-mentioned explanation that attaches firm PE protective membrane embodiment, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation that does not break away from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
