滑組成物に関するものである。DETAILED DESCRIPTION OF THE INVENTION Technical Field Related to the Invention The present invention relates to rust prevention of hot-rolled pickled steel sheets, cold-rolled steel sheets, and plated steel sheets (hereinafter referred to as steel sheets) from the time they are coated until they are shipped, and the prevention of rust during pressing. The present invention relates to a lubricating composition for steel plates that can improve lubricity in a single treatment.
従 来 技 術
鋼板は貯蔵中、輸送中、または受入後使用されるまでの
防錆を目的に防錆油の塗布や、防錆紙による梱包または
両者の併用によって発錆を防いでいる。Conventional technology: To prevent rust during storage, transportation, or after receipt and use, conventional steel sheets are coated with anti-rust oil, packed with anti-rust paper, or both are used in combination to prevent rust.

等を塗布後にプレス加工に供される。Before using a steel plate coated with rust preventive oil, the package must be unpacked and the applied rust preventive oil must be removed. After unpacking and removing the applied rust-preventing oil, the steel plate is, for example, a steel plate for automobiles, coated with press working oil or the like again and then subjected to press working.

添加したものである。Conventionally used rust preventive oils are based on petroleum-based mineral oils, such as spindle oil and turbine oil, to which rust preventive agents such as petroleum oxides or petroleum sulfonic acid calcium salts or barium salts are added. The main thing is what you do. Furthermore, conventionally used lubricating oils for press working are petroleum-based mineral oils to which oiliness improvers such as fatty acids and higher alcohols, or extreme pressure agents such as phosphoric acid esters, chlorinated paraffins, and sulfurized oils and fats are added.

。゛ The process using such anti-rust oil or press processing oil requires a lot of time and effort, such as application of anti-rust oil → packaging → unpacking → degreasing → application of press processing oil, and the labor costs for materials and disposal of waste. Combined with this, there was a problem of huge waste of labor and time.

力である。In order to solve these drawbacks, rust-preventing lubricants that have both anti-corrosion and lubricity properties and can omit the process of applying press working oil have been studied, and several have been put into practical use. These compositions use natural oils such as beef tallow, palm oil, and coconut oil, or synthetic esters synthesized from fatty acids of natural oils and fats and various alcohols as a base oil, and Oa salts and Ba salts of petroleum oxides and petroleum sulfonic acids. The main products are those with added .
しかし、防錆潤滑剤は潤滑性、防錆性、脱脂性等多くの
性能が要求されるが、これらの特性をすべて満足するも
のがないと同時に、潤滑性においても充分な性能が得ら
れていないのが現状である。However, anti-rust lubricants are required to have many properties such as lubricity, rust prevention, and degreasing properties, but there is no product that satisfies all of these properties, and at the same time, sufficient performance in terms of lubricity has not been achieved. The current situation is that there is no such thing.
発 明 の 目 的
本発明は1回の処理にて潤滑性および防錆性が良好で、
脱脂性に優れた鋼板用潤滑組成物を提供することである
。Purpose of the Invention The present invention provides good lubricity and rust prevention with a single treatment.
An object of the present invention is to provide a lubricating composition for steel plates having excellent degreasing properties.

等を挙げることができる。The organic acids used in the present invention include monovalent acids and divalent acids, and -valent acids include, for example, acetic acid,
Mention may be made of tetrapionic acid, butyric acid, valerian acid, cabtetranic acid, enantylic acid, and as dihydric acids, for example oxalic acid, malonic acid, succinic acid, geltaric acid, adipic acid, pimelic acid, apple acid. Acids, maleic acid, fumaric acid, etc. can be mentioned. Examples of the aliphatic alcohol include diuryl alcohol, myristyl alcohol, valmityl alcohol, heptyl alcohol, stearyl alcohol, beef tallow alcohol, and coconut oil alcohol.

よび脱脂性との関係を示すグラフである。The reason why the number of carbon atoms in the organic acid is limited to the range of 2 to 7 in the present invention is that as shown in Figure 1, if the number of carbon atoms is less than 2, the lubricity in the deep drawing test will be poor, and if it exceeds 8, the lubricity will be poor. This is because the lubricity decreases. Figure 1 shows the relationship between carbon number and lubricity of an organic acid measured using heptyl alcohol as the alcohol; 'J 9/-g as the adhesion amount and conditions similar to Example 1 described later as deep drawing conditions. This is a graph showing. In addition, the number of carbon atoms in aliphatic alcohol is 12.
The reason for limiting the range to 18 is that as shown in Figure 2, if the carbon number is less than 12, the lubricity in the deep drawing test is poor, and as shown in Figure 8, if the carbon number exceeds 18, the degreasing property is poor. To become. Figures 2 and 8 show succinic acid as the organic acid; 0.8 g/III as the amount of adhesion
and is a graph showing the relationship between the carbon number of higher alcohol and lubricity and degreasing property measured using conditions similar to Example 1 described below as deep drawing conditions.

のと思われる。When applying the limited range of low carbon number organic acids, aliphatic higher alcohols, and esters of the present invention to steel sheets as described above, compared to conventional esters based on fatty acids having 8 to 18 carbon atoms, (1) Excellent lubricity; (2)
It was confirmed that the following effects could be obtained: (3) excellent rust prevention properties and (3) excellent degreasing properties. However, although the reasons for this are not clear, the use of lower fatty acids improves their adsorption to steel sheets, and the long-chain higher alcohols provide excellent coating properties, providing lubricity and rust prevention. It seems that sex will improve. In addition, because it is a lower fatty acid, it is likely to be easily saponified by alkaline degreasing and has good degreasing properties.

ことができる。When the lubricating composition for steel plates of the present invention is used to treat steel plates, the composition is heated and melted and applied to the surface of the steel plate by dipping, roll booting, electrostatic coating, or spraying. Additionally, the composition can be diluted with mineral oil, solvent, etc. to improve workability.

097−が望ましい。Furthermore, as the amount of the composition of the present invention applied increases, the lubricity and rust prevention properties can be improved, but if the amount is too large, slipping occurs when cutting a steel plate to a specified length, making it difficult to obtain accurate dimensions. At the same time, the steel plates overlap and become difficult to separate.
This will interfere with later work. Therefore, the coating amount is 0.2 to 2.
097- is desirable.
