Embodiment

[0098] Next, regarding the lubricating composition of the present invention, the lubricating composition-coated metal sheet, and the method for producing a lubricating composition-coated metal sheet, specifically Be explained.

no. 1 Embodiment

[0100] A coating layer composed of the lubricating composition shown in Table 1 was formed on both sides or one side of a metal plate (thickness: 1 mm), and a plurality of lubricating composition-coated metal plates were produced, and their characteristics were evaluated.

[0101]

[0102] According to the compounding quantity shown in Table 1, the lubricating composition was prepared. When preparing, use an oil bath to heat to about 90°C to make it melt, and stir until it is homogeneous.

[0103] Next, the lubricating composition was heated to 90° C. to melt it, and applied to the surface of a metal plate (thickness 1 mm) shown in Table 1 using an electrostatic oiler (manufactured by Lubtic Co., Ltd.). Allow to cool to form a lubricating coating.

[0104]

[0105] The lubricating composition was prepared in the compounding quantity shown in Table 1, and it was dissolved in toluene to prepare a paint (paint concentration: 5% by mass) containing the lubricating composition...

no. 2 Embodiment

[0139] For single side 0.8g / m 2 In the same way as in Example 1 above, the lubricating composition shown in Table 4 is coated on electro-galvanized steel sheets (thickness 1mm, plating adhesion: 30g / m 2 ) formed on both sides of the lubricating composition-coated metal plate, the characteristics were evaluated in the same manner as in the above-mentioned first example.

[0140] It should be noted that the melting peak temperature of the lubricating composition, electrical resistance, and the method of measuring the amount of the lubricating composition attached to the metal plate coated with the lubricating composition, as well as stability, formability, release property, blocking resistance, and weldability The evaluation method and evaluation criteria are the same as those of the above-mentioned first embodiment.

[0141] These results are shown in Tables 4 and 5. It should be noted that in Table 4, values ​​that do not satisfy the scope of the present invention are underl...

Abstract

The invention provides a lubricant composition capable of improving the punch forming property, demoulding property, block resistant property and welding property of stable metal plates, and a lubricant composition coated metal plate coated by the lubricant composition. Furthermore, the invention provides a manufacturing method of the lubricant composition coated metal plate for forming the lubricant composition coated layer having the properties on the metal plates in low cost, high efficiency without generating great environmental loads. The lubricant composition comprises waxes having paraffin and polyoxyethylene alkyl ethers, characterized in that, the melting peak temperature prescribed in the JIS K7121 is above 35 DEG C, and the polyoxyethylene alkyl ethers are selected from at least one of polyoxyethylene cetyl ether, polyoxyethylene octadecyl ether, polyoxyethylene docosyl ether and polyoxyethylene lanolin alcohol ether.

Description

technical field [0001] The present invention relates to a lubricating composition used in press forming of a metal plate, a lubricating composition-coated metal plate coated with the lubricating composition, and a method for producing the lubricating composition-coated metal plate. Background technique [0002] From industrial products such as automobiles, home appliances, and business machines to daily necessities such as beverage cans, sinks, and bathtubs, stamping of metal plates is used in a wide range of fields, and it occupies a very important position in plastic processing. Generally, in order to prevent scratches on the surface of dies and metal plates due to poor lubrication when performing press processing, lubricity and processability are improved by applying press oil (lubricating oil) at present. However, in recent years, for example, in order to meet the demand for lightweight automobiles, there have been more and more examples of high-strength steel sheets and...
