It spends for 0.1-0.2mm, the material of tinplate layer is tinplate, thickness 0.5-1mm, and corrosion-resistant coating is PET film layer, thickness
It spends for 0.1mm-0.2mm.It plays only one layer of PET film layer of anti-corrosion function for this kind of tinplate, and the preservative tank service life is actual
For PET film layers, the sum total in tinplate layer service life；In addition, food cans are that PET film layer first is combined to substrate in production
On substrate is drawn high again, formed tank body, PET film is easily damaged during drawing high, and then causes antiseptic property
Reduction, therefore need further to be improved for the existing can of food.
The content of the invention
To overcome deficiency of the prior art, the utility model provides a kind of anticorrosive tin plate food pot.
To achieve the above object, the technical solution adopted in the utility model is as follows：A kind of anticorrosive tin plate food pot, bag
It includes and molding tank body is drawn high by substrate, further include organic coating, anti-rotten film layer, the water-separating film outwards set gradually by inner tank wall
Layer, the one side that the inner tank wall is contacted with organic coating are rough surface, and the organic coating is sprayed at the base before tank body shaping
On plate, hot pressing welding is compound on the substrate before tank body shaping and the thickness of anti-rotten film layer successively for the anti-rotten film layer, water proof film layer
Degree is more than organic coating and the thickness of water proof film layer.
Further, substrate is tin plate, its yield strength of the substrate is between 525MPa-530MPa, tensile strength
Between 530MPa-535MPa, elongation percentage is then between 2.8MPa-3.2MPa.
Further, organic coating is ethylene-vinyl alcohol copolymer.
Further, the thickness of organic coating is 0.05-0.1mm.
Further, anti-rotten film layer is PET film.
Further, the thickness of anticorrosive film layer is 0.3-0.4mm.
Further, water-separating film is PP films.
Further, the thickness of water-separating film is 0.1-0.2mm.
Further, the outer wall of tank body is equipped with protection film layer, before which is compound in tank body shaping
On substrate.
Further, protection film layer is composite plastic film, and the thickness of the protection film layer is more than 0.2mm.
From the above description of the utility model, it can be seen, compared with prior art, anticorrosive horse provided by the utility model
Mouth iron food cans since substrate surface is equipped with multilayered structure, control its index performance so that breakage rate drops when substrate stretches
Low, ratio of briquetting improves；Organic coating, anti-rotten film layer and water proof film layer, protection multilayer structure co-ordination, can carry out mutually each other
It mends, forms the anti-corrosion effects of multilayer；This kind of anticorrosive tin plate food pot, good appearance, convenient for production, corrosion resistance
Good, health has a vast market potentiality.
Description of the drawings
Fig. 1 is the structure diagram of anticorrosive tin plate food pot；
Fig. 2 is the structure diagram of the tank body substrate of anticorrosive tin plate food pot.
Specific embodiment
Below by way of specific embodiment, the utility model will be further described.
Show referring to figs. 1 to Fig. 2, a kind of anticorrosive tin plate food pot, including tank body 1, organic coating 2, anti-rotten film layer 3,
Water proof film layer 4 and protection film layer 5, organic coating 2, anti-rotten film layer 3, water proof film layer 4 are outwards set gradually by 1 inner wall of tank body,
Protection film layer 5 is arranged at 1 outer wall of tank body；
Tank body 1 is once drawn high shaping by substrate, and the one side that 1 inner wall of tank body is contacted with organic coating 2 is rough surface, the substrate
For tin plate, yield strength is between 525MPa-530MPa, tensile strength is between 530MPa-535MPa, and elongation percentage is then
Between 2.8MPa-3.2MPa, substrate 1 uses electrolysis process that substrate surface is made to form rough surface before spraying；
Organic coating 2 is ethylene-vinyl alcohol copolymer, which is sprayed on the substrate before tank body shaping, spraying
Thickness is 0.05-0.1mm, and coating thickness is 0.06mm in the present embodiment；
Anti- corruption film layer 3 is PET film, which is compound on the substrate before tank body shaping, anti-corrosion film
The thickness of layer is 0.3-0.4mm, and the thickness of anti-corrosion film layer is 0.35mm in the present embodiment；
Water proof film layer 4 is PP films, which is compound in anti-rotten film layer 3, the thickness of water proof film layer 4
For 0.1-0.2mm, the thickness of the present embodiment interval water film 4 is 0.15mm；
Protection film layer 5 is composite plastic film, which is compound on the substrate before tank body shaping, this
The thickness of protection film layer is 0.5mm in embodiment.
Show referring to figs. 1 to Fig. 2, above-mentioned anticorrosive tin plate food pot, using tin plate as substrate, due to substrate surface
Equipped with multilayered structure, therefore the index of its yield strength, tensile strength and elongation percentage is controlled, the effective organic painting for ensureing multilayer
Layer 2, anti-rotten film layer 3, the breakage rate of water proof film layer 4, protection film layer 5 when substrate stretches reduce, and improve ratio of briquetting；
