The present invention relates to a cold rolling oil for steel sheets containing a base oil selected from mineral oil, synthetic ester, or a mixture thereof, to which an oil-soluble anionic substance is added, and a water-soluble cationic polymer emulsifying powder. Cold rolling is performed by adding various additives to animal and vegetable oils such as beef tallow and palm oil, various synthetic esters, mineral oils, or mixtures thereof and emulsifying and dispersing them in water, which is then cyclically sprayed onto the steel plate surface and roll surface. It is being said. As emulsifiers used to make these oils into stable emulsifying dispersions, the use of nonionic, anionic, and cationic emulsifying and dispersing agents is introduced in the literature in Kogyo Materials Vol. 19, No. 4. There is. The lubricating oil is 1 to 50 depending on the addition of emulsifier and dispersant and mechanical stirring power.
The particles become micro-sized particles and are emulsified and dispersed. The resulting particles are protected by a film of the adsorbed emulsifying and dispersing agent, and coalescence of the particles is prevented by the electrostatic repulsion of the electric double layer. In order to obtain stable emulsifying and dispersing properties, the emulsifying and dispersing agent must quickly adsorb around oil particles to form an adsorption film and provide an appropriate zeta potential. The water-soluble cationic polymer emulsifying and dispersing agent is adsorbed onto the surface of the oil particles and imparts a positive zeta potential to the oil particles. The higher the adsorption density of the emulsifying dispersant or the stronger the adsorption film is against mechanical shearing, the better the emulsifying dispersion stability is. Since the oil particles themselves become negatively charged by mechanical stirring, there is a strong electrical element in their adsorption with the water-soluble cationic dispersant. The present invention has been made in view of these circumstances, and its purpose is to provide a cold rolling oil for steel sheets with excellent emulsifying and dispersing properties. The present invention, which has been made to achieve this object, uses a base oil selected from mineral oils, synthetic esters, or mixtures thereof, such that the zeta potential of water-dispersed particles of the base oil is -70 mV or more base oil. to which one or more oil-soluble anionic substances such as oil-soluble organic acids, animal and vegetable oils containing free fatty acids, and oil-soluble acidic phosphate esters are added in advance, and one cationic nitrogen atom is added in one repeating unit.
A cold rolling oil for steel sheets, characterized in that it contains one or more water-soluble cationic polymer emulsifying dispersants having at least one water-soluble cationic polymer emulsifying dispersant, wherein the zeta potential of the water-dispersed particles of the base oil is -70 mV or more. When the oil-soluble anionic substance is added to the base oil in advance to make it more base, stable emulsifying and dispersing properties are achieved due to the presence of the water-soluble cationic polymer emulsifying dispersant during dispersion in water. It shows. When beef tallow containing ordinary free fatty acids, which is the base of rolling oil, is emulsified and dispersed by mechanical stirring, the zeta potential is -70 mV, and relatively good emulsifying and dispersing properties can be achieved by using a water-soluble cationic polymer emulsifying dispersant. However, in the case of mineral oil and/or synthetic ester, the zeta potential is nobler than -50 mV, and good emulsifying and dispersing properties cannot be obtained with water-soluble cationic polymer emulsifying and dispersing agents. However, when an oil-soluble anionic substance is added, its zeta potential decreases and -
Good emulsion dispersion stability can be obtained when the voltage is less than 70 mV. This is considered to be because by reducing the zeta potential of the lubricating oil particles, the adsorption density of the water-soluble cationic polymer emulsifying dispersant increases and the adsorption force becomes stronger. The oil-soluble anionic substances used in the present invention include oil-soluble organic acids such as stearic acid, oleic acid, dimer acid, alkenylsuccinic acid, and benzoic acid, animal and vegetable oils containing free fatty acids, dioleyl phosphate, and dipalmityl. It is selected from oil-soluble acidic phosphoric acid esters such as phosphate and distearyl phosphate, and oil-soluble acidic borate esters such as dioleyl borate, dipalmityl borate, and distearyl borate. One or more of the substances can be arbitrarily selected and added to the base oil. Examples of the polymer emulsifying and dispersing agent having one or more cationic nitrogen atoms in one repeating unit in the present invention include polyamine, polyethyleneimine, N.N.
Examples include salts of acetic acid, phosphoric acid, boric acid, etc., such as dialkylaminoethyl polyacrylate and cationic modified products of polyacrylamide, and one or more of these salts can be arbitrarily selected and used. In the cold rolling of steel plates, rolling oil emulsified and dispersed in water is used, but when using the rolling oil of the present invention, in addition to using the rolling oil of the present invention emulsified and dispersed in water, An oil-soluble anionic substance is added to the base oil in advance so that the zeta potential of the water-dispersed particles of the base oil selected from mineral oil, synthetic ester, or a mixture thereof is -70 mV or less; A water-soluble cationic polymer emulsifying dispersant having one or more cationic nitrogen atoms in one repeating unit may be added to water and emulsified and dispersed. Examples and comparative examples are given below to explain the effects of the rolling oil of the present invention in detail. Sample oil 1: 95 parts of 120 machine oil (same below parts by weight)
5 parts of stearic acid was added and dissolved in the sample oil 2: 96.5 parts of 120 machine oil and 3.5 parts of stearic acid.
Sample oil 3: 97.5 parts of 120 machine oil and 2.5 parts of stearic acid
Sample oil 4: 120 parts of machine oil and 2 parts of stearic acid added and dissolved. Sample oil 5: 120 parts of machine oil and 1 part of stearic acid added to 99 parts of machine oil. Measurement of zeta potential of test oil 6:120 machine oil: 3% (same weight below) of each test oil was added to water heated to 60℃, and each was mixed with a homomixer.
After stirring at 10,000 rpm for 10 minutes, the zeta potential of the water-dispersed particles was measured. Emulsion dispersion stability test: After adding 3% of each test oil to water, acetate of N.N dimethylaminoethyl polymethacrylate (average molecular weight 5 x 10 4 ) was added to each liquid.
After adding 300 ppm, the liquid was heated, adjusted to 60°C, and stirred for 30 minutes at 10,000 rpm using a homomixer, and then the particle size of the water-dispersed particles was measured. Next, after the above stirring, the stirring force was further weakened to 5000 rpm and stirred for 30 minutes, and then the particle size of the water-dispersed particles was measured to examine the degree of change in particle size due to the difference in stirring force. The smaller the change in particle size, the better the emulsion dispersion stability. The above test results are shown in Table 1.

以上の試験結果を第２表に示す。[Table] Test oil 7: 97 parts of stearic acid methyl ester (synthetic ester) and 3 parts of oleic acid added and dissolved. Test oil 8: 120 parts, machine oil 50 parts and beef tallow (acid value 6) 50 parts.
Sample oil 9: A mixture of 49 parts of 120 machine oil and 49 parts of stearic acid methyl ester, with 2 parts of dioleyl phosphate added and dissolved. Test oil 10: Stearin Acid methyl ester 100 parts Test oil 11:120 Machine oil 90 parts Beef tallow (acid value 6) 10
Measurement of zeta potential: As described above. Emulsion dispersion stability test: Tests for test oils 7 to 11 were carried out in the same manner as in the above test except that the water-soluble cationic polymer emulsification dispersants added were different as shown in Table 2. The above test results are shown in Table 2.
