Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to soy sauce, a surfactant,
The present invention relates to a resin laminated can suitable for storing relatively corrosive contents such as flavors, seasonings, and chemicals.

[0002]

2. Description of the Related Art As a metal container for filling with highly corrosive chemicals, paints, and foods as contents, a can, which is conventionally called an Atron can, having a polyethylene bag fitted inside the container has been used. However, due to the recent increase in environmental awareness, when disposing of the container, the inner polyethylene bag and the metal can must be separated and collected, which is a complicated work on the part of the user, which is one of the causes of high work cost. It was.

Further, as another type of metal container, an 18 L can or a pate having an inner coating specification in which an epoxy resin is double-coated is used.
Although a tin can is used, there are problems such that a large amount of paint solvent (VOC) is discharged and the cost is high because double coating is performed.

In contrast to these conventional techniques, Japanese Patent Laid-Open No. 7-23
Japanese Patent No. 2731 proposes a large square can in which the portion other than the electric resistance seam welded portion is laminated with a biaxially stretched polyester film. In this case, the film can be laminated by pressure bonding with an adhesive or by heat-sealing the film itself. However, since the adhesion between the biaxially stretched polyester film and the adhesive is poor, when a large square can produced by the above technique is filled with a coating material containing a solvent such as xylene or toluene, delamination or delamination occurs in a short time. Rust occurs, the corrosion resistance to the contents (hereinafter referred to as "content corrosion resistance") is insufficient, and film peeling occurs when the can body is expanded like a pail can. I found it easy.

A technique for bringing a film and a metal plate into close contact with each other is disclosed in JP-A-61-149340.
By making polyethylene terephthalate (PET) amorphous and non-oriented, it is possible to improve the adhesiveness with the metal plate. However, in this case, the remaining crystallized part is PE
Since it is less in the T layer, the barrier property is greatly reduced.

Therefore, after heating a metal plate above the melting point of PET and bonding it to the film, it is immediately water-cooled to amorphize only the PET portion in contact with the metal plate surface, leaving the crystallized portion in the upper layer of the film. Methods are commonly used. However, the above method has a very small allowable range of laminate conditions, a low production yield, and when a highly corrosive content is filled, a sufficient barrier property can be obtained only by the upper crystal layer. Therefore, there is a problem that rusting is still likely to occur.

The PET layer of the above technique is laminated using a single material. In JP-A-8-238720, a polyester resin film having a two-layer structure is heat-sealed or adhesive-bonded. Laminated steel sheets have been proposed, but this laminated steel sheet has excellent adhesion to the metal plate of the polyester resin of the lower layer, especially when the polyester resin film using an adhesive is adhered, but Due to the low barrier property of the polyester resin, rusting easily occurs in a short time when the contents containing the organic solvent are filled. In addition, there is a problem that a large number of grinding dusts and pinholes due to welding spatter are generated during can making, and sufficient corrosion resistance to the contents cannot be obtained.

[0008]

SUMMARY OF THE INVENTION According to the present invention, a resin laminated metal plate having excellent barrier properties of a resin film and adhesion of a resin film to a metal plate is used for a body and a base and / or canopy, and xylene is used. It is an object of the present invention to provide a resin laminated can having excellent corrosion resistance against contents that are highly corrosive such as paints containing a solvent such as toluene and toluene, alkaline detergents, soy sauce, seasonings, so-called contents corrosion resistance.

[0009]

Means for Solving the Problems As a result of intensive studies to solve the above problems, the present invention has completed the following inventions. That is, the gist of the present invention is as follows. (1) In a resin laminated can in which a resin laminated metal plate is used for a body and a ground cover and / or a canopy, the resin laminated metal plate has a thermosetting resin layer on at least one surface of the metal plate constituting the resin laminated metal plate. Which has a copolymerized polyester resin layer obtained by copolymerizing a dicarboxylic acid component consisting of terephthalic acid and isophthalic acid, and a diol component on the thermosetting resin layer. A resin laminate can, comprising an oriented polyester resin layer obtained by polymerizing a dicarboxylic acid component composed of 100 mol% terephthalic acid and a diol component containing 98 mol% or more ethylene glycol on the top. (2) The resin laminate can according to the above (1), wherein the body and the ground cover and / or the canopy are integrated by joining by double winding.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION An example of an embodiment of the present invention will be described in detail below. In order to suppress rusting due to the strongly corrosive contents filled in the can, (a) generally improve the barrier property (permeability and hardness) of the resin film, and (b) metal. It is important to satisfy both the excellent adhesion between the plate and the resin film.

That is, when the barrier property of the resin film is inferior, the permeability of the corrosion factor becomes high, and when the content containing the organic solvent is filled, rusting easily occurs in a short time. This is because the hardness becomes insufficient, a lot of grinding dust during can making and pinholes due to welding spatter are generated, and sufficient corrosion resistance of the contents cannot be obtained. Here, the pinhole resistance refers to the difficulty of generating grinding dust during can making and pinholes (eaves of film, etc.) due to welding spatter. In addition, even if the barrier property of the resin film is excellent,
This is because if the adhesion between the metal plate and the resin film is poor, rusting is likely to occur.

Therefore, in order to satisfy the above (a),
A method is conceivable in which a polyester layer having a large plane orientation coefficient or a thermosetting resin layer such as epoxy-phenol resin or polyester-isocyanate is provided in the film. Also,
In order to satisfy the above (b), a method of adhering the film to the metal plate with an amorphous polyester layer having a small plane orientation coefficient or a method of adhering the film and the metal plate with a thermosetting resin can be considered.

[0013] Therefore, the inventors studied the optimum film structure and found that in order to satisfy the above (a), a structure having two layers of a polyester resin layer having a large plane orientation coefficient and a thermosetting resin layer was used. In addition, it has been found that, in order to satisfy the above (b), it is preferable to apply a polyester resin layer having a small plane orientation coefficient to the steel sheet via the thermosetting resin layer.

Further, the adhesion between the polyester resin layer and the thermosetting resin greatly affects the plane orientation coefficient of the polyester. If the plane orientation coefficient is a certain value or more, delamination during processing tends to occur, but it is appropriate. It was also found that if the surface orientation coefficient is large, sufficiently strong interlayer adhesion is obtained, and as a result, the corrosion resistance of the contents and the adhesion after processing are improved.

Based on these findings, the oriented polyester resin layer having a high plane orientation coefficient excellent in barrier property is used as the upper layer, and the copolymerized polyester resin layer having a low plane orientation coefficient excellent in adhesion to a metal plate is used as the lower layer. By applying a two-layered polyester resin composite layer on a metal plate via a thermosetting resin layer as an adhesive, the above (a) and (b)
It was found that both of the above can be satisfied, and as a result, the corrosion resistance of the contents and the adhesion to the steel sheet are improved.

That is, the resin laminated can of the present invention is
A resin laminated metal plate is used for a body and a ground cover and / or a canopy, and the resin laminated metal plate has a thermosetting resin layer on at least one surface of a metal plate constituting the resin plate, and the thermosetting resin. A dicarboxylic acid component consisting of terephthalic acid and isophthalic acid and a copolymerized polyester resin layer obtained by copolymerizing a diol component are provided on the layer, and 100 mol% of terephthalic acid is provided on the copolymerized polyester resin layer. It has an oriented polyester resin layer obtained by polymerizing a dicarboxylic acid component and a diol component containing 98 mol% or more of ethylene glycol.

The copolymerized polyester resin layer and the oriented polyester resin layer of the resin laminated metal plate used in the resin laminated can of the present invention are both saturated polyester resins, which are obtained by condensation polymerization of a diol component and a dicarboxylic acid component. The thermoplastic polyester resin obtained is represented by polyethylene terephthalate / isophthalate copolymer and polyethylene terephthalate.

(I) Metal Plate As the metal plate used as the base material of the resin laminated metal plate used in the present invention, for example, steel, aluminum, copper, etc. in the form of sheet, coil, or foil are used. The one
And those obtained by subjecting them to surface treatment. The thickness of the metal plate is not particularly limited, but in order to satisfy both can strength and weight reduction in a well-balanced manner, 0.1 to 0.5 mm
It is preferable that it is within the range.

The metal plate is an electrolytic chromic acid treated metal plate (TFS) having a two-layer structure of a lower layer of chromium metal and an upper layer of chromium hydrate oxide from the viewpoints of corrosion resistance, can-making processability, can strength and corrosion resistance. ), Or tin-based steel with Ni-diffused or Ni-flash-plated steel with tin-plated reflow-treated tin-containing steel, ultra-thin tin-plated steel, and granular dispersed Sn-plated steel. A metal chromium layer and a chromium hydrate oxide layer are sequentially applied on a plated steel sheet,
Alternatively, it is possible to use the above-mentioned steel plate and aluminum plate, a nickel-plated steel plate, a zinc-plated steel plate, which have been subjected to a phosphate treatment, a dichromic acid treatment, and a chromium-chromate treatment.

(Ii) Copolymerized Polyester Resin Layer The copolyester resin layer is made of a material in which a dicarboxylic acid component consisting of terephthalic acid and isophthalic acid and a diol component are copolymerized at a molar ratio of 1: 1. .

The dicarboxylic acid component must be composed of two kinds, terephthalic acid and isophthalic acid. A polyester obtained by polymerizing a dicarboxylic acid component other than terephthalic acid and isophthalic acid and one or more kinds of diol components deteriorates the adhesiveness with the thermosetting resin in contact with the metal plate, and when processed, forms a polyester resin layer. This is because the delamination phenomenon easily occurs at the interface of the thermosetting resin layer. The molar ratio of terephthalic acid to isophthalic acid is not particularly limited, but the ratio of isophthalic acid is preferably 5 to 30 mol%, more preferably 7 to 25 mol%. This is because if the amount of isophthalic acid is less than that, the adhesion tends to decrease, and if it is more than that, the strength of the adhesive layer itself tends to decrease.

As the diol component, ethylene glycol, diethylene glycol, butylene glycol
1,4-butanediol, 1,5-pentanediol, 1,6-hexanediol, propylene glycol, polytetramethylene glycol, polyethylene glycol, neopentyl glycol, 1,4-cyclohexanedimethanol, trimethylolpropane, pentaerythritol It is preferable to use one or two or more selected from the above.

Particularly, in terms of improving the adhesiveness with the thermosetting resin,
It is more preferable to copolymerize a dicarboxylic acid component composed of terephthalic acid and isophthalic acid with a diol component composed of one or two kinds of ethylene glycol and butylene glycol.

The copolyester resin layer preferably has a plane orientation coefficient in the range of 0.01 to 0.15. If the plane orientation coefficient is less than 0.01, the barrier property may be lowered and sufficient corrosion resistance of the contents may not be obtained, and if it exceeds 0.15, the amorphous part is reduced, so that the heat hardening in contact with the steel sheet This is because the adhesion with the resin is deteriorated, and during processing, an interlayer peeling phenomenon is likely to occur at the interface between the polyester resin layer and the thermosetting resin layer.

As a method of adjusting the plane orientation coefficient within the range of 0.01 to 0.15, for example, it can be adjusted according to the stretching ratio when the polyester film is stretched.

The film thickness of the copolyester resin layer is 0.1
˜10.0 μm, more preferably 0.5 to 0.8 μm, in terms of adhesion to the thermosetting resin layer and corrosion resistance of the contents. If it is less than 0.1 μm, the adhesiveness will decrease,
This is because if it exceeds 10.0 μm, a film shift may occur between the upper oriented polyester resin layer during processing.

(Iii) Oriented polyester resin layer The oriented polyester resin layer comprises a dicarboxylic acid component consisting of 100 mol% terephthalic acid and a diol component containing 98 mol% or more ethylene glycol in a molar ratio of 1: 1. It is made of polymerized material.

The dicarboxylic acid component must consist of 100 mol% terephthalic acid. 100 mol of terephthalic acid
When it is%, an extremely high crystal blending property is obtained by stretching during the film production, and the barrier property and pinhole resistance as a film are remarkably improved, and terephthalic acid is less than 100 mol%, that is, When a dicarboxylic acid component other than terephthalic acid is present, the crystal orientation due to stretching during film formation is lower than that of a film with 100 mol% terephthalic acid, and the effect of improving the barrier properties and pinhole resistance of the film is reduced. Is.

As the diol component, ethylene glycol, diethylene glycol, butylene glycol 1,4-butanediol, 1,5-pentanediol, 1,6-hexanediol, propylene glycol, polytetramethylene glycol, polyethylene glycol, neo 1 selected from pentyl glycol, 1,4-cyclohexanedimethanol, trimethylolpropane, pentaerythritol, etc.
It is preferable to use one kind or two or more kinds.

Particularly, a polyester polymerized by using terephthalic acid as a dicarboxylic acid component and one or two kinds of ethylene glycol and butylene glycol as a diol component is preferable from the viewpoint of corrosion resistance and cost.

The orientation polyester resin layer preferably has a plane orientation coefficient in the range of 0.05 to 0.18, preferably 0.16 to 0.18. If the surface orientation coefficient is less than 0.05, the barrier property against the contents is lowered, and the surface hardness is lowered, so that scratches and pinholes are likely to occur, while
If it exceeds 0.18, it tends to shrink during heating, and problems such as a decrease in the precision of the film edge portion tend to occur. As a method of adjusting the plane orientation coefficient within the range of 0.05 to 0.18, for example, it can be adjusted according to the draw ratio when the polyester film is drawn. Here, the "stretch ratio" means the ratio of the stretched film length to the unstretched film length.

The surface orientation coefficient can be measured by measuring the refractive index with an Abbe refractometer.
The plane orientation coefficient ΔP can be obtained by the formula shown below.
ΔP = (β + γ) / 2−α, where α is the refractive index in the thickness direction, β is the refractive index in the width direction, and γ is the refractive index in the longitudinal direction.

As a method for separating the polyester resin composite layer having a two-layer structure into an upper layer and a lower layer, for example, it is preferable to use a microtome and precisely grind the upper layer side and the lower layer side.

The thickness of the oriented polyester resin layer is 10 to
It is preferably 70 μm. If it is less than 10 μm, the barrier property of the film tends to be insufficient, and the corrosion resistance of the content tends to deteriorate, and if it exceeds 70 μm, the internal stress of the film becomes large and film peeling may occur during overhang processing. Because there is.

Further, the thickness of the oriented polyester resin layer is 1 to 100 with respect to the thickness of the copolyester resin layer.
It is preferable to set the double range. If it is less than 1 time, the corrosion resistance of the contents and film shift are likely to occur, and if it exceeds 100 times, the oriented polyester resin layer becomes too thick and the internal adhesion increases due to the deterioration of processing adhesion. Because there is a risk of doing so.

(Iv) Thermosetting resin layer For the thermosetting resin layer, it is preferable to use an epoxy-phenol resin or a polyester-isocyanate resin in terms of adhesion and corrosion resistance. When using an epoxy-phenolic resin, the number average molecular weight of the epoxy resin used is preferably 2000 to 14000, more preferably 3
It is 000 to 12000. When the number average molecular weight of the epoxy resin is less than this range, the strength of the thermosetting resin layer is lowered, and the adhesion is lowered. On the other hand, when the number average molecular weight is larger than this range, the curing time becomes long and the productivity is lowered. The thickness of the thermosetting resin layer is preferably 0.3 to 6.0 μm in order to obtain good adhesiveness with the metal plate and the polyester film.

Next, using the resin laminated metal plate having the above structure,
An example of the method for producing the resin laminated can of the present invention will be described below. As the polyester resin composite layer having a two-layer structure of a copolyester resin layer and an oriented polyester resin layer constituting the resin laminated metal plate of the present invention, a polyester film formed by a coextrusion method and biaxially stretched is used. To form.

In addition, the polyester film having a two-layer structure of the copolymerized polyester resin layer and the oriented polyester resin layer has a heat shrinkage ratio in the width direction (TD) of the film at an ambient temperature in the range of 140 ° C. to 220 ° C. Is 3.0% or less, and the thermal shrinkage in the longitudinal direction (MD) of the film is preferably 4.0% or less. If the shrinkage ratio exceeds the above numerical value, the dimensional accuracy of the unbonded portion for welding may be affected, and a can of the same quality may not be produced. Here, the heat shrinkage rate of the film means the shrinkage rate after fixing a film having a standard length and leaving it in an atmosphere of a set temperature for 5 minutes, as described in ASTM D1204.

The thermosetting resin layer may be formed by coating either surface of the polyester film or the metal plate with, for example, a coater and then drying to form a film. It is preferable to form a film from the viewpoint of film thickness uniformity. The coating conditions are not particularly limited, but drying to the extent that the solvent of the thermosetting resin is evaporated is preferable, and specifically, it is 5 to 140 ° C to 170 ° C.
It is desirable to do this for ~ 60 seconds.

The resin-laminated metal plate used in the present invention can be produced by pressure-bonding the polyester film with the metal plate heated and held at 160 to 215 ° C. and then water cooling. Here, the metal plate temperature at the time of crimping the polyester film is 160 to 215 ° C., because when the polyester film is crimped at less than 160 ° C., the copolyester resin layer of the lower layer does not melt, so that the thermosetting This is because there is a risk that the adhesion with the resin layer will deteriorate, and if treated at a temperature above 215 ° C,
This is because the equipment cost for heating and holding the metal plate at this temperature becomes large, and there is a possibility that the problem of increasing the energy consumption rate may occur.

Next, using the above-mentioned resin laminated metal plate, the inner surface side of the can body is made a polyester resin laminated (laminated) surface,
The outer surface is painted or printed, or the outer surface is resin-laminated, and then canned. At this time, when the resin is laminated on both the inner and outer surfaces, it is preferable to simultaneously bond the resin film, and in the case of coating the outer surface, the baking temperature is preferably 140 to 190 ° C.

When the resin-laminated can is a welded can, unbonded portions of the resin film are provided on both ends of the body, and the portions are electrically resistance-welded. Thereafter, repairs are performed to form a film on the welded portion. Need to be applied.

As the repair method, a polyester resin tape is used, a resin film is formed on the welded portion through an adhesive or by heat fusion, or a polyester or epoxy powder coating film is used. Is preferably formed.

In addition, in 18L cans and top plate fixed type pail cans,
The hand ring is joined by projection welding, and furthermore, in the top plate detachable pail can, the ear is joined by projection welding for attaching the hanging hand. Since the resin film surface on the inner surface of the positioned can is deteriorated by welding heat and pinholes tend to be generated, these parts are also
It is preferable to apply the above-mentioned repair method.

The above is merely an example of the embodiment of the present invention, and various modifications can be made within the scope of the claims.

[0046]

(3) Pinhole resistance evaluation test Using each of the above resin laminated steel sheets, 10 18 L cans were manufactured and
The number of pinholes generated on the body of the L can was measured with a wet pinhole meter.
The grade was evaluated. Table 3 shows the evaluation results. Table 3

From the evaluation results shown in Table 3, in all the examples, the adhesion of the polyester resin composite layer to the steel sheet,
As a result of having both excellent pinhole resistance, it can be seen that the corrosion resistance of the contents is also excellent, and in addition, the dimensional stability is also excellent. On the other hand, in each of the comparative examples, sufficient corrosion resistance of the contents is not obtained because at least one of the adhesion of the polyester resin composite layer to the steel sheet and the pinhole resistance is inferior.
