Abstract
The utility model discloses a metal surface protective film. The protective film comprises a PET (Polyethylene Terephthalate) base material layer located on the lower surface of the protective film, an organic silicone resin adhesive layer compounded on the upper surface of the protective film, and a chemical treatment layer arranged between the PET base material layer and the organic silicone resin adhesive layer, wherein the organic silicone resin adhesive layer is a mixture layer of tetraalkoxy titanate, tetraalkoxy silane and siloxane, and the chemical treatment layer is a mixture layer of nitric acid, sulfuric acid and ethanol. The protective film disclosed by the utility model comprises the PET base material layer, the organic silicone resin adhesive layer and the chemical treatment layer, the organic silicone resin adhesive layer is strong in temperature resistance, and the PET base material layer treated by the chemical treatment layer can be more fully contacted with the organic silicone resin adhesive layer, so as to reach the purposes that the protective film can be stably attached to the surface of a metal sheet even at high temperature, and the phenomenon of residual adhesive does not happen when the protective film is torn off.
Description
Technical field
The utility model relates to a kind of protective membrane, particularly a kind of metal surface protection film.
Background technology
For avoiding damaging in process of manufacture in the surface that makes sheet metal; usually attach in its surface protective membrane; the adhesive-layer of the disclosed protective membrane of prior art is take acryl glue as main body mostly; and the temperature tolerance of acryl glue is not good; when temperature raises, its chemical bond can rupture; cause adhesive-layer to come off from substrate layer; and then cause protective membrane to come off from sheet metal surface; not only make it lose the protection effect; also can the cull phenomenon occur at sheet metal surface, directly have influence on the aesthetic appearance of sheet metal.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of metal surface protection film, be attached at sheet metal surface to reach also can stablize in high temperature, and the purpose of cull phenomenon appears in the Shi Buhui that tears.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of metal surface protection film; comprise the PET substrate layer that is positioned at the protective membrane lower surface; described protective membrane upper surface is compounded with the silicone resin adhesive-layer; be provided with the chemical treatment layer between described PET substrate layer and described silicone resin adhesive-layer; described silicone resin adhesive-layer is the mixture layer of four titan-alkoxide acid esters, tetraalkoxysilane and siloxanes, and described chemical treatment layer is the mixture layer of nitric acid, sulfuric acid and ethanol.
Preferably, described PET substrate layer thickness is 0.06mm.
Preferably, the sticking silica gel adhesive-layer thickness of described height is 0.02mm.
Preferably, described chemical treatment layer thickness is 0.001mm.
Pass through technique scheme; a kind of metal surface protection film that the utility model provides comprises PET substrate layer, silicone resin adhesive-layer and chemical treatment layer; the temperature tolerance of silicone resin adhesive-layer is strong; can be more abundant contiguously with the silicone resin adhesive-layer through the PET substrate layer that the chemical treatment layer was processed; realized in high temperature stablely being attached at sheet metal surface, and the purpose of cull phenomenon appears in the Shi Buhui that tears.
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 description of the Prior Art.
Fig. 1 is the disclosed a kind of metal surface protection film cross-sectional schematic of the utility model embodiment.
The represented corresponding component title of numeral in figure:
1, PET substrate layer 2, silicone resin adhesive-layer 3, chemical treatment layer
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
According to Fig. 1; the utility model provides a kind of metal surface protection film; comprise and be positioned at the PET substrate layer 1 that protective membrane lower surface thickness is 0.06mm; the protective membrane upper surface is compounded with the silicone resin adhesive-layer 2 that thickness is 0.02mm; being provided with thickness between PET substrate layer 1 and silicone resin adhesive-layer 2 is 0.001mm chemical treatment layer 3; silicone resin adhesive-layer 2 is made of four titan-alkoxide acid esters, tetraalkoxysilane and silicone cross-linked curing, and chemical treatment layer 3 is mixture layers of nitric acid, sulfuric acid and ethanol.
A kind of metal surface protection film that the utility model provides comprises PET substrate layer 1, silicone resin adhesive-layer 2 and chemical treatment layer 3; wherein; the main body of silicone resin adhesive-layer 2 is siloxanes; use four titan-alkoxide acid esters and tetraalkoxysilane to carry out crosslinking curing as catalyzer; the silicone resin adhesive-layer 2 that crosslinking curing generates is chemical bond easy fracture not when temperature change, and temperature tolerance is strong.
Carry out corrosion treatment on 3 pairs, coating silicone resin adhesive-layer 2 front use chemical treatment layer PET substrate layer 1 surface, after processing, one deck minute aperture can appear in PET substrate layer 1 surface, make when coating silicone resin adhesive-layer 2, contact between PET substrate layer 1 and silicone resin adhesive-layer 2 is more abundant, more firm in conjunction with getting, the utlity model has also can stablize in high temperature and be attached at sheet metal surface, and tear and the advantage of cull phenomenon can not occur.
To the above-mentioned explanation of disclosed a kind of metal surface protection film 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 be in the situation that do not break away from spirit or scope of the present utility model, realization 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.
