Abstract
The utility model relates to a gas-phase rust-proof composite film which comprises a surface layer and an inner layer, wherein the surface layer is a polyethylene (PE) layer; the inner layer is common metal product packing paper; a rust-proof agent layer is arranged between the surface layer and the inner layer; and the rust-proof agent layer is coated on one of the surfaces of the surface layer in advance. Compared with the prior art, a PE film is taken as the surface layer to be arranged on one of the surfaces of the metal product packing paper, and the PE film is compact in texture, so that the manufactured composite packaging film is high in mechanical strength and is not easily torn when in package; and corrosive gases such as water vapor and the like can not easily pass through the composite packaging film, so that the composite packaging film has good protecting function for metal products. In addition, the rust-proof agent layer additionally arranged between the surface layer and the inner layer is slow in volatilization, so that the service life of the gas-phase rust-proof composite film is longer than that of the existing rust-proof packing paper.
Description
[technical field]
The utility model relates to a kind of packing, refers to be used for the gas phase rust prevention complex film of metalwork packing especially.
[background technology]
Each metal packing material is generally the paper that contains antirust composition (inhibiter) in the prior art, common name rust prevention packaging paper, it need adopt thicker paper, and as art paper, craft paper etc., described paper immerses to take out to dry after a period of time in the solvent that contains antirust composition and gets final product.Through soaking, the paper quality becomes loose, and mechanical strength is not enough, breaks easily when packing is used.Antirust composition has volatility, and it volatilizees away via paper surface, and the paper two sides is exposed in the air, and the volatilization area is big, volatilizees soon, so this rust prevention packaging paper life-span is short.Though the described local composite gas-phase anti-rust paper intensity of utility model patent CN2606128Y is good, but its structure is at the local composite bed that contains compound PE film on the anti-rust base paper of VCI, compound PE film on local composite bed again, composite polyethylene woven cloth again, this complex structure, the cost height, and the life-span of body paper falls short of equally.The described technology contents of utility model patent CN2441846Y is the same with patent CN2606128Y all to be the one side that antirust film is compounded in body paper, rather than be compounded between anti-rust base paper and the PE layer, more than service life of two described gas phase rust prevention complex films of patent all reach desirable state inadequately.
[utility model content]
The technical problems to be solved in the utility model is the problem that exists at existing rust prevention packaging paper, and a kind of mechanical strength height, long gas phase rust prevention complex film of life-span are provided.
The technical solution of the utility model is: gas phase rust prevention complex film, comprise top layer and internal layer, and described top layer is the PE layer.
Internal layer described in the utility model is common metalwork wrapper.
It between top layer described in the utility model and the internal layer antirust composition layer.
The layer of antirust composition described in the utility model is coated on one of them surface, top layer in advance.Compare with prior art, the utility model is located at one of them surface of metalwork wrapper with the PE film as the top layer, because the membranous ground of PE closely, the composite package film mechanical strength height of making, be not easy during packing to tear, aggressive fumes such as while aqueous vapor are not easy by this composite package film, and metalwork is played good protective action.In addition, the antirust composition layer volatilization of setting up between top layer and the internal layer is slow, and the life-span of this product, existing rust prevention packaging paper was long.
Description of drawings
Fig. 1 is the utility model first embodiment section-drawing.
Fig. 2 is the utility model second embodiment section-drawing.
[specific embodiment]
As shown in Figure 1, gas phase rust prevention complex film comprises top layer 1 and internal layer 2, and described top layer 1 is PE layer (polyethylene).Described internal layer preferable alloy goods wrapper is as craft paper, art paper etc.This complex film is formed by top layer 1 and internal layer 2 coextru-laminations, or heat-sealing is composited.The membranous ground of PE that is located at the top layer is tight, and the composite package film mechanical strength height of making like this is not easy during packing to tear, and aggressive fumes such as while aqueous vapor are not easy by this composite package film, and metalwork is played good protective action.
As shown in Figure 2, present embodiment and the foregoing description difference be, the top layer surface compound with internal layer 2
Be coated with one deck antirust composition (inhibiter) 3 in advance.Because antirust composition has volatility, after gas phase rust prevention complex film was made, it is middle with internal layer 2 that antirust composition layer 3 is positioned at top layer 1, and antirust composition just volatilizees slowly like this, and the life-span of this product, existing rust prevention packaging paper was long.
Protection domain of the present utility model is not limited to the foregoing description, as long as the PE layer is made as the top layer, reaches the technical pattern that is provided with the antirust composition layer between packing body paper and PE layer and all belongs to protection domain of the present utility model.
Claims (4)
1. gas phase rust prevention complex film, it comprises top layer (1) and internal layer (2), described top layer (1) is the PE layer.
2. gas phase rust prevention complex film according to claim 1 is characterized in that: described internal layer (2) is common metalwork wrapper.
3. gas phase rust prevention complex film according to claim 1 is characterized in that: be antirust composition layer (3) between described top layer (1) and the internal layer (2).
4. gas phase rust prevention complex film according to claim 3 is characterized in that: antirust composition layer (3) is coated on one of them surface, top layer (1) in advance.
