Abstract
The utility model relates to a foaming coating type all-plastic gas-phase rustproof composite film for rust prevention and protective packaging of steels and a manufacturing method thereof. The all-plastic gas-phase rustproof composite film comprises a multi-layer co-extruded film layer, a foaming film layer is covered on one surface of the multi-layer co-extruded film layer, and a gas-phase corrosion inhibitor is coated on the foaming film layer. The Multi-layer co-extruded film extruded via an extruder is poured on the foaming film layer so as to form the composite film compounded via the multi-layer co-extruded film layer and the foaming film layer through a compound machine, or the multi-layer co-extruded film with the foaming film layer is extruded via the extruder, and then the foaming film layer is coated with the gas-phase corrosion inhibitor to form the composite film. The all-plastic gas-phase rustproof composite film has fine packaging rustproof property, physical property and mechanical strength of the multi-layer co-extruded film are obviously superior than those of a single-layer plastic film, the foaming film layer can have a relatively fine packaging protection function, and the used rustproof composite film can be completely recycled and reused, thereby not only reducing waste, but also being favorable for protecting environments. In addition, the forming coating type all-plastic gas-phase rustproof composite film is simple and convenient in production process and low in manufacturing cost.
Description
Technical field
The utility model relates to the foaming application type all-plastic gas phase rust prevention complex film that a kind of steel are antirust, protective packaging is used, and belongs to packaging steel material technology field.
Background technology
In the prior art,, pack, to play double action antirust and protection as volatile rust preventive papers commonly used such as thin plate coil of strips to the iron and steel metallic article after the processing.Existing volatile rust preventive paper is to be coated substrate with paper, at its surface coating rust inhibitor, and in the compound PE film of the another side of paper or one deck PE woven cloth, to strengthen its intensity and waterproof moisture resistance performance.Yet only compound its physical strength of PE film is obviously not enough, and many by drenching film PE layer and the compound operation of paper with the PE woven cloth, cost is than higher.Though be problematic in that this anti-tarnish paper serviceability is preferably arranged, but because paper is not easily separated after compound, its discarded object of back of unpacking can not be recycled, and this not only causes the waste of paper and plastics resource, and discarded anti-tarnish paper also can cause very big pollution to environment because of can not natural degradation.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiency that above-mentioned prior art exists and provides that a kind of operation is simple, serviceability good, cost is lower, and the all-plastic gas phase rust prevention complex film that can recycle.
The utility model for the all-plastic gas phase rust prevention complex film technical scheme that the problem that solves above-mentioned proposition adopts is: include multi-layer co-extruded rete, be covered with the foaming rete in the one side of multi-layer co-extruded rete, be coated with vapour phase inhibitor on the foaming rete.
Press such scheme, described multi-layer co-extruded rete is 3～5 layers.
Press such scheme, described PP TYPE tunic layer material be among PE, PP, EVA, PA, the EVOH any one or multiple.Be the monofilm layer material for wherein a kind of, the stratified film material can be identical or different.
Press such scheme, described foaming rete is PE or PP foaming rete.
Press such scheme, between multi-layer co-extruded rete and foaming rete, be provided with leaching membrane layer.
Press such scheme, the content of coated gas phase corrosion inhibitor is that every square metre of vapour phase inhibitor solids content is 10～15g on the described foaming rete.
The utility model all-plastic gas phase rust prevention complex film is extruded the PP TYPE pouring by extruder and form multi-layer co-extruded rete and the mutually compound composite membrane of foaming rete by compounding machine on the foaming rete, when perhaps extruding PP TYPE by extruder, make outermost skim foaming and add an amount of hydroaropic substance therein to form the PP TYPE that contains the rete that foam, then coated gas phase corrosion inhibitor on the rete that foams.
Another kind of preparation method of the present utility model is that the multi-layer co-extruded rete of moulding is compounded to form multi-layer co-extruded rete and foaming rete mutually compound composite membrane by compounding machine with leaching membrane layer with the foaming rete, then coated gas phase corrosion inhibitor on the rete that foams.
The beneficial effects of the utility model are: 1, because the foaming rete has good absorbent properties, by the agent of coating vapor phase corrosion inhibitor (antirust), and coating weight is controlled by technological requirement, make to the utlity model has good packing rustless property, and the foaming rete can play better packing safeguard function; 2, the barrier property of PP TYPE is strong, can intercept steam and oxygen effectively and plays the antirust effect of waterproof; 3, the physical property of PP TYPE and mechanical strength obviously are better than single-layer plastic film, and PP TYPE can be carried out 3 or 5 layers of co-extrusion as requested, each layer can adopt with a kind of plastic raw materials, also can adopt plastic raw materials not of the same race to be combined into different raw material retes and change multi-layer co-extruded film strength, produce the compound gas phase anti-tarnishing film of the plastics that meet various requirement of strength, when satisfying the different product packing instructions, can at utmost reduce production costs like this; 4, the rust prevention complex film after using can recycle and reuse fully, promptly cuts the waste and helps environmental protection; 5, production technology is easy, and cost of manufacture is low.
The utility model rustless property detects with reference to the QB1319-91 test method and carries out, and its testing result is as follows:
| Pilot project | Experimental result | Experimental condition |
| The volatile rust prevention screen(ing) test | 9 cycles are rustless | T：50±2℃；RH： 95％ |
| Dynamically contact damp heat test | 9 cycles are rustless | T：49±1℃；RH： ＞95％ |
| The vapor phase corrosion inhibitor ability test | 9 cycles are rustless | T：40±1℃；RH： 95％ |
