Description
Technical field
The utility model relates to a kind of high temperature resistant BOPP isolation film of aluminizing, and belongs to the technical field that bidirectional stretching polypropylene film structure is improved.
Background technology
In the casting of iron and steel class, when surface is smooth especially, is difficult to separate between two-layer, bidirectional stretching polypropylene film (BOPP) can be added between two layers of iron and steel, make it easily be separated.But general BOPP is because fusing point is at about 165 DEG C, needs iron and steel to cool and just can isolate with it, reduce efficiency, cause and use limitation.
Utility model content
The purpose of this utility model is to provide a kind of dystectic high temperature resistant BOPP isolation film of aluminizing.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of high temperature resistant BOPP isolation film of aluminizing, be composited successively by aluminium coated one, bidirectional stretching polypropylene film layer, aluminium coated two, wherein, the thickness of aluminium coated one is 0.8-1 μm, the thickness of bidirectional stretching polypropylene film layer is 10-60 μm, and the thickness of aluminium coated two is 0.8-1 μm.
As the further setting of such scheme, the thickness of described aluminium coated one is preferably 1 μm, and the thickness of aluminium coated two is preferably 1 μm.
The utility model is high temperature resistant aluminizes BOPP isolation film, is all compounded with aluminium coated in the upper layer of bidirectional stretching polypropylene film, about improving fusing point to 175 DEG C, decreases iron and steel cool time, improves efficiency.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model is high temperature resistant aluminizes BOPP isolation film, be composited successively by aluminium coated 1, bidirectional stretching polypropylene film layer 2, aluminium coated 23, wherein, the thickness of aluminium coated 1 is 0.8-1 μm, the thickness of bidirectional stretching polypropylene film layer 2 is 10-60 μm, and the thickness of aluminium coated 23 is 0.8-1 μm.
The thickness of aluminium coated 1 is preferably 1 μm, and the thickness of aluminium coated 23 is preferably 1 μm.The thickness of bidirectional stretching polypropylene film layer 2 is selected in the scope of 10-60 μm according to customer requirement.
In the utility model, the material of bidirectional stretching polypropylene film layer 2 is homopolymerization PP.
Above-described embodiment only illustrates inventive concept of the present utility model for explaining, but not the restriction to the utility model rights protection, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should fall into protection domain of the present utility model.
