- a layer that does not melt at a high temperature, that is, a layer 13 having an orientation can be reliably left.
- the resin coating on the laminating roll 5 is determined by the heating temperature of the metal plate, the feeding speed of the metal plate, the composition, thickness, plane orientation coefficient, and moving distance of the deflector 7 in the P1 direction.
- the state of the resin layer after being laminated on the metal plate which is a feature of the resin-coated metal plate of the present invention, will be described.
- the resin film When the resin film is brought into contact with a metal plate heated above the melting point of the resin film and crimped, the resin film loses its orientation due to the heat conducted from the metal plate. Moreover, the direction is closer to the outermost layer.
- the surface orientation coefficient of the resin layer on the side directly contacting the metal plate of the resin film laminated on one surface (A) of the metal plate is ⁇ 1 ⁇
- the outermost resin layer The surface orientation coefficient of the resin layer laminated on the other surface ( ⁇ ) of the metal plate is 11 ⁇
- the surface orientation coefficient of the resin layer on the side directly in contact with the metal plate is n lu
- the outermost resin layer When the plane orientation coefficient of n 2 U is n 2 U , n 1 A and n are 0 to 0.04, ⁇ 2 0 is 0.02 to 0.10> n 2 U is 0 to 0.10, and n ⁇ n ⁇ must be used.
- n 1 A and n l B is 0.04 of the metal plate surfaces of the metal plate and directly adjoin ⁇ fat layer, thin deep drawn cans
- the resin layer laminated on the inner and outer surfaces of the can easily peels off from the surface of the metal plate. If the plane orientation coefficient is 0.04 or less, the resin layer is not peeled off, so it is necessary to set the coefficient to 0.04 or less.
- the resin layer that is in direct contact with the metal plate corresponds to the melt layer formed by heating, and is a layer that contributes to the processing adhesion.
- the inner and outer surfaces of the can have a plane orientation coefficient in the range of 0 to 0.04.
- the plane orientation coefficient measured from the refractive index is the average value of the part from the outermost surface of the resin film peeled from the metal plate to a depth of about 5 m.
- the plane orientation coefficient of the outermost resin layer actually in contact with the metal plate is 0, that is, even if it is non-oriented, the plane orientation coefficient exceeds 0 if there is an oriented portion within the depth.
- ⁇ 1 ⁇ and n 1 B are set to 0 to 0.04 in the resin-coated metal plate of the present invention is such a result.
- the plane orientation coefficient ⁇ 2 ⁇ of the outermost resin layer of the resin film laminated on each surface is 0.02 to 0.10 and n 2 B is 0 to 0. 10 and It is necessary to keep n 2u ⁇ n 2 in consideration of the workability, corrosion resistance, and impact resistance of the resin-coated metal plate of the present invention.
- the barrier property of the resin layer itself against the content is significantly reduced, and is particularly preferable on the inner surface of the can in direct contact with the content to be filled. Absent. If both the plane orientation coefficients n 2A and ⁇ 2 ⁇ exceed 0.10, severe molding processing is performed even if the plane orientation coefficients ⁇ ⁇ and ⁇ ⁇ of the resin layer directly in contact with the metal plate are less than 0.04. When this occurs, countless cracks enter the upper resin layer, making it unpractical as a can. Therefore, the surface orientation coefficient ⁇ 2 ⁇ of the outermost resin layer must be maintained in the range of 0.02 to 0.10.
- ⁇ 1 ⁇ ⁇ 2 and ⁇ 1 ⁇ ⁇ 2 ⁇ are set in the method for producing a resin-coated metal plate of the present invention in that the laminated resin film is heated to a temperature equal to or higher than the melting point of the laminated resin film. Since it is heated and melted from the surface in contact with the metal plate, the plane orientation coefficient is inevitably as described above. That is, the plane orientation coefficient of the laminated resin layer is present with a gradient in the thickness direction from the surface in contact with the metal plate.
- the plane orientation coefficient of the resin film used is also an important factor, and the plane orientation coefficient of the resin film exceeds 0.17
- the surface orientation coefficient ⁇ 2 ⁇ and ⁇ 2 ⁇ of the outermost resin layer are less than 0.15, making direct contact with the metal plate It is extremely difficult to make the plane orientation coefficients ⁇ ⁇ and ⁇ , ⁇ of the resin layer less than 0.10. Therefore, the resin used for lamination
- the plane orientation coefficient of the film is preferably 0.17 or less, more preferably about 0.15.
- the resin film used for lamination and the plane orientation coefficient ⁇ ⁇ of the resin layer and the outermost resin layer in contact with the metal sheet after lamination on the metal sheet, nn ⁇ 2 ⁇ and n 2B are obtained by the following method.
- the plane orientation coefficient of the resin film used is obtained from the following equation by measuring the refractive index in the vertical, horizontal and thickness directions with an Abbe refractometer.
- the resin-coated metal plate is immersed in hydrochloric acid, the surface of the metal plate is chemically dissolved, only the resin layer is peeled off, and the surface of the obtained resin layer in contact with the metal plate
- the refractive index in the vertical, horizontal and thickness directions is measured in the same manner as described above, and the refractive index can be determined using the above equation.
- the plane orientation coefficient of the laminated resin film indicates the degree of crystal orientation of the resin film, but when a pigment or the like is added to the resin, the plane orientation coefficient can be measured. It can be difficult. In such a case, the measurement can be performed using an X-ray diffraction method, an IR method (infrared ray method), or the like. A method for measuring the degree of orientation of a polyethylene terephthalate film by an X-ray diffraction method will be described as an example.
- the depth of X-rays penetrating into the resin film was set to 5 m.
- the resin films laminated on both sides of the metal plate include polyethylene terephthalate, a copolymerized polyester resin mainly composed of ethylene terephthalate repeating units, polybutylene terephthalate, and butylene terephthalate.
- a polyester resin consisting of a polyester resin mainly composed of repeating units, a polyester resin blended with at least two types of these polyester resins, or a multilayer polyester resin laminated with at least two types of the above polyester resins.
- the resin film is a two-layer resin film made of a polyester resin obtained by blending at least two kinds of the above, and a resin in which the lower layer is made of a blend of the above-mentioned thermoplastic resin and the polycarbonate resin. After forming the film, the film is stretched in two directions, and used as a biaxially oriented resin film produced by heat setting.
