物に関する。Detailed Description of the Invention [Field of Industrial Application] The present invention provides a water-based lubricant composition for use in flame-retardant high water content hydraulic oils, metal working oils such as rolling oils and cutting oils, and also as coolants. Regarding.

量％以上とした難燃性高含水作動油が開発されている。Traditionally, water-based lubricant compositions have been used as flame-retardant hydraulic oils, metalworking oils, coolants, etc., but flame-retardant hydraulic oils contain 35% to 45% by weight of glycol in a water-based fluid. %
, water-glycol-based products containing 10% to 20% by weight of polyether thickener and a water content of about 35% to 50% are known, and recently, high molecular weight polyethers have been developed. A flame-retardant high water content hydraulic oil has been developed in which the water content is 95% by weight or more by adding 1% to 5% by weight.

テル順の使用量も多く、これも又コストの問題、鉱油系
の作動油に比して性能が悪いという問題がある。However, the former requires a large amount of glycol or polyether to adjust the viscosity to a specified level, resulting in high costs, and the problem is that it is less dusty than mineral oil-based hydraulic fluids even in terms of wear resistance. In addition, during use, the viscosity of the latter decreases due to cleavage of polyether molecular chains, resulting in a decline in its functionality as a hydraulic fluid.Additionally, a large amount of polyether is used to adjust the viscosity to a specified level. There are problems with cost and poor performance compared to mineral oil-based hydraulic fluids.

のであり、腐敗しやすい、また使用済液の後処理が困難
である等の問題が指摘されている。Similarly, when it comes to water-based metalworking oils, conventional metalworking oils use surfactants as their main ingredient to make base oils such as mineral oils and synthetic oils water-soluble. Problems have been pointed out, such as the fact that it is easily putrefied and post-processing of the used liquid is difficult.

腐敗等の問題がない金属加工油等の水系潤滑剤組成物の
提供を課題とする。The present invention provides a flame-retardant, highly water-containing hydraulic fluid that can provide high viscosity even with a small amount of thickener used, has almost no decrease in viscosity during use, and has excellent abrasion resistance. An object of the present invention is to provide a water-based lubricant composition such as metal working oil that does not have such problems.
Ｃ課題を解決するための手段〕
本発明の水系潤滑剤組成物は、架橋型高吸水性ポリマー
を水をベースとする流体に添加したことを特徴とする。Means for Solving Problem C] The water-based lubricant composition of the present invention is characterized in that a crosslinked superabsorbent polymer is added to a water-based fluid.
このよう架橋型高吸水性ポリマーは、公知のものを使用

ルアルコール系、ポリエーテル系等の分子内架橋を有す
る架橋型高吸水性ポリマーを使用するものである。Known cross-linked superabsorbent polymers can be used, such as polyacrylate-based, isobutylene/maleate-based, starch/polyacrylate-based, and polyvinyl alcohol/polyacrylate-based polymers. A crosslinked superabsorbent polymer having intramolecular crosslinking such as polyacrylamide, hydrophilic acrylic polymer, polyvinyl alcohol, or polyether is used.

なく、またＩＱ ｍｍｏｌ／ ｇを越えると吸水性が小

離しゃすくなるので好ましくない。The crosslinking density of such a crosslinked superabsorbent polymer is 0. OO] mmol/g ~I Q+n+n
ol/g N desirably 0,05 mmol/
It is best to use one with a crosslinking density of 0.g to 5 mmol/g, and a crosslinking density of 0.5 mmol/g. If it is less than 0.001 mmol/g, the molecular shape of the polymer becomes close to linear, which is undesirable because the viscosity decreases due to shearing etc. during use as a hydraulic oil or metal processing oil, and if it exceeds IQ mmol/g, the water absorption property decreases. This is not preferable because the viscosity increasing effect is small and it is easy to separate from water.
このような架橋型高吸水性ポリマーは、常温で微粒子状
又は粘性物であり、本発明ではそのどちらの形状でも使

５０μｍを越えると容易に水から凝集、分離しゃすくな
るので好ましくない。Such a crosslinked superabsorbent polymer is in the form of fine particles or a viscous substance at room temperature, and in the present invention, either form can be used. However, in the case of fine particles, the particle size is preferably 150 μm or less, and preferably is 0.1 μm to 70 μm
By using particles with a finer particle shape, high shear resistance and abrasion resistance can be achieved.
If it exceeds 50 μm, it is not preferable because it easily aggregates and separates from water.
また、架橋型高吸水性ポリマーにおける吸水率は、５０

ものは水に添加して潤滑剤としても、吸水物が分離し、
作動油、金属加工油に要求される分散性がよくない。In addition, the water absorption rate of the crosslinked superabsorbent polymer is 50
It is better to use a product with a water absorption rate of 50 times or more, and a product with a water absorption rate of less than 50 times can be added to water and used as a lubricant, but the water absorption will separate,
The dispersibility required for hydraulic fluids and metal working fluids is not good.
これらの架橋型高吸水性ポリマーは、水に対して０．０
０５重量％〜１重量％添加されるのみで充分、作動油及
び金属加工油として機能させることができる。添加量が
０．００５重量％未満であると添加効果がなく、また１
重量％を越える添加量は吸水力との関係で無意味である
。These cross-linked super absorbent polymers have a water content of 0.0
Adding only 0.05% to 1% by weight is enough to function as a hydraulic oil and a metal working oil. If the amount added is less than 0.005% by weight, there will be no addition effect;
Addition amounts exceeding % by weight are meaningless in relation to water absorption.

使用下では線状ポリマーの剪断が生じ、粘性が低下する
という問題を有する。Linear polymers such as polyethers, which are currently used in high water content hydraulic fluids, have a small molecular weight and show a certain improvement in lubricity as the viscosity increases, but when the molecular weight is large, lubricity is not improved,
Therefore, when used as a thickener, it is necessary to use a relatively large amount of one with a low molecular weight, and when used for a long time, shearing of the linear polymer occurs, resulting in a decrease in viscosity.

It has been discovered that it has high viscosity, high shear stability, and wear resistance, and can be made suitable as a lubricant composition for hydraulic oils, metal working oils, and the like.

示し、長時間での潤滑性を保持しつるものと思われる。The detailed reason for this is unknown, but the structure of cross-linked superabsorbent polymers has a three-dimensional network structure, and upon contact with water, hydrophilicity develops due to hydroxyl groups, carboxylic acid groups, etc. in the structure. Water is absorbed into the network structure by the action of water and osmotic pressure, but by swelling this cross-linked super absorbent polymer with water and making it into a water-based lubricant composition, it can be used as a hydraulic oil or metal working oil. It was discovered that a crosslinked superabsorbent polymer in a water-absorbed state exhibits excellent dispersion stability and thickening properties, and the viscosity can be easily adjusted. In addition, even when water is absorbed, the crosslinked superabsorbent polymer has strong flexibility due to its network structure, and does not break like linear polymers on friction surfaces such as pistons and cutting surfaces, and has high shear stability and resistance. It is thought to exhibit anti-wear properties and maintain lubricity over a long period of time.
以下、実施例により本発明を説明する。The present invention will be explained below with reference to Examples.
〔実施例１〕
水に、架橋型高吸水性ポリマーとして、イソブチレン／
マレイン酸塩系ポリマー（粒径４μｍ１架橋度２ ｍｍ
ｏｌ／ ｇ ｓ吸水率３００倍）を０．１重量％、０．
５重量％それぞれ含有させ、本発明の水系潤滑剤組成物
を調製した。[Example 1] Isobutylene/
Maleate-based polymer (particle size 4 μm, degree of crosslinking 2 mm)
ol/g s water absorption rate 300 times), 0.1% by weight, 0.
A water-based lubricant composition of the present invention was prepared by containing 5% by weight of each.
各試料組成物及び水の粘度を、ＪＩＳＫ２２８３により
温度を変えて測定した。The viscosity of each sample composition and water was measured according to JIS K2283 at varying temperatures.
その結果を下記に示す。The results are shown below.
（以下余白） 粘度の単位は、ｍｍ”／ｓである。(Margin below) The unit of viscosity is mm''/s.
架橋型高吸水性ポリマーの添加量に応じて水系潤滑剤組
成物の粘性が増加し、増粘剤として機能することがわか
る。It can be seen that the viscosity of the water-based lubricant composition increases depending on the amount of the crosslinked superabsorbent polymer added, and it functions as a thickener.
