Description

When processing a metal or non-metal material, a mineral-based lubricating oil has been frequently used to reduce friction between materials that rub against each other. However, in the field of lubricants, development of environment-friendly lubricants is strongly desired from the viewpoints of deterioration of the global environment due to heavy use of mineral substances, deterioration of environment at the manufacturing work site of machine parts, and resource depletion.
The present invention relates to an environmentally friendly plant food material-based lubricant that replaces the conventional mineral-based lubricating oil. Made by effectively combining plant-based and food-drinking products, including ethyl alcohol or shochu made from plants, soy lecithin, a plant-based surfactant, and coffee or tea liquor, which is your favorite beverage. The present invention relates to an environment-friendly plant food-based lubricant.

Conventionally, mineral-based lubricating oils are often used when materials rub against each other, such as during processing of metal materials. However, there are problems such as deterioration of the global environment, especially not being friendly to people at the manufacturing work site of machine parts, and resource depletion.
There are conventional vegetable lubricants, for example, JP-A-10-180391, 2008-231422 or 2010-168519, but these do not remove residual mineral oil from the previous step of the material in advance. In addition, it is difficult to apply the lubricant to the material, or, in JP-A-2016-196618, the image of the environment is impaired because the lubricant component contains something other than food and drink. There are many practical problems.

It is desirable that the lubricant to be put into practical use is friendly to the global environment, friendly to workers at the manufacturing work site, and easy to apply to conventional processes.

The present inventor, as a result of various studies to solve the above problems, when the materials rub against each other, in place of the conventional mineral-based lubricating oil, ethyl alcohol or shochu made from plants, soybean lecithin, preference It was found that by using a so-called vegetable food-based lubricant prepared by stirring and dissolving a liquid containing coffee liquid or tea liquid, which is a beverage, it has good material processability due to its excellent lubricating performance. And completed the present invention.
The present invention relates to an environment-friendly liquid plant food material-based lubricant produced by effectively combining plant foods and drinks.

The lubricant of the present invention is ethyl alcohol or shochu made from plants, vegetable soybean lecithin, and coffee liquor or tea liquor, such as tea leaves or wheat, rice grains, etc., Japanese tea, black tea, barley tea, brown rice tea, etc. It is a liquid plant food lubricant containing the tea liquor and the remaining water. It has excellent antiseptic properties, lubricity, and the advantage that even if the conventional mineral oil remains on the surface of the material from the pre-application process, it can be applied as it is. Further, it is possible to easily remove the attached lubricant from the surface of the material after the lubricant is used, so that the lubricant can be easily handled. The lubricant of the present invention is liquid and used at room temperature.
The liquid component system of the lubricant of the present invention comprises a component system containing ethyl alcohol or shochu, soybean lecithin, coffee liquor or tea liquor, and residual water.

Ethyl alcohol is a commonly used and commonly used fermented ethanol of plant origin. Shochu is also a general shochu made from sugar cane, rice, wheat, potato, corn, etc. as a raw material, and depending on the content of ethyl alcohol contained, for example, the alcohol content is 20, 25 or 35. Lecithin is also a common plant soybean lecithin and is usually a dark brown mucus. Coffee liquor also coffee liquor obtained from coffee beans, tea liquor is also commonly used in liquids such as Japanese tea obtained from tea leaves, black tea, etc. and wheat, barley tea obtained from brown rice grains, brown rice tea, etc. Is also commercially available. The raw material for both is plant.
As described above, since the raw material of the lubricant of the present invention is a plant-based food and drink, it is gentle to humans, improves the global environment, and is a semi-permanent resource that can be obtained by growing the plant. The lubricant of the present invention can be used as a countermeasure from both aspects of environment and resources.
The lubricant of the present invention uses beverages such as shochu, coffee liquid, etc., but it is not drinkable.

Each component of the lubricant of the present invention and the content range thereof are as follows. All percentages in the content range are% by mass. Further, the purity of ethyl alcohol and the alcohol content of shochu are generally expressed as volume %, but in the present invention, volume% and mass% are treated as the same.
The ethyl alcohol content is 4% or more and 7% or less. The ethyl alcohol content in this case is used in consideration of the purity of the ethyl alcohol liquid used.
When shochu is used instead of ethyl alcohol, the range of ethyl alcohol content of shochu should be equivalent to the range of ethyl alcohol content. For example, when the ethyl alcohol content is 4% to 7%, the amount of shochu to be used, that is, the content range, is 20% to 35% when the alcohol content is 20, 16% to 28% when the alcohol content is 25, and the frequency. In the case of 35, it is 12% to 20%. The alcohol content of the shochu used is 36 or less. Although it is possible to combine shochus with different frequencies, in this case, it is decided to add from those with a low frequency to those with a high frequency, and the total content range of the shochu compounding is within the range of the high frequency, and It is possible to combine ethyl alcohol and shochu, but in this case as well, the total combined range is set to the ethyl alcohol content range.
The content range of soybean lecithin of vegetable lecithin is 10% or more and 24% or less.

The content range of the coffee liquid and the tea liquid is 4% or more and 20% or less.
Coffee liquid is a common drink, for example, so-called drip coffee obtained by adjusting the mass ratio of coffee powder made by grinding roasted coffee beans and hot water poured into it to 1:20 to 30, or roasted coffee. Roasted coffee beans are placed in hot water, and the mass ratio of the beans to the hot water is maintained at 1 to 20 to 30 and then the coffee liquid obtained by removing the beans, or tea such as tea, black tea, barley tea and brown rice tea. The liquid is also prepared in a generally practiced manner, and is a tea liquid obtained by removing tea leaves or tea grains after holding tea leaves, black tea leaves, barley tea grains or brown rice tea grains in hot water. There are also commercially available coffee and tea liquors. You may mix coffee liquid and tea liquid. The content range of the composite total at that time is also 4% or more and 20% or less.

Liquid plant food-based lubricants obtained by stirring and dissolving liquids containing these liquids retain antiseptic properties, liquid homogeneity, good coating properties, excellent lubricating performance, and materials after use. It also has a function of easily removing the attached lubricant from the surface.

The method for producing the lubricant of the present invention is as follows.
In a liquid container, ethyl alcohol or shochu, soybean lecithin in a viscous liquid, coffee liquid or tea liquid, and a liquid containing residual water are mixed and stirred. After stirring, the liquid has a pale yellowish milky white color. After that, a floating substance may be formed in the upper layer part of the liquid, a precipitate may be formed in the lower layer part, or a deposit may be formed on the wall of the container. In this case, although it can be used as a lubricant as it is, it is desirable to remove it because removal of these will facilitate the handling of the liquid. In this manufacturing method, the degree of dissolution of each component by stirring the liquid is visually determined.

The lubricant can be applied to both the front and back surfaces of the plate material to be processed, or to one side, and even if there is surface adhesion of so-called mineral oil, etc. that comes from the pre-manufacturing process of the material to be processed, Since this lubricant can be applied to the material surface without degreasing it in advance, this lubricant can be easily applied to the conventional material processing process using mineral oil, and it can be easily switched to the conventional process. It is possible.

The materials to be rubbed with each other in the present invention are metal or non-metal materials such as steel-based, stainless-based, high-alloy-based, titanium-based, aluminum-based, and copper-based materials, and their shapes are not specified.

INDUSTRIAL APPLICABILITY The lubricant of the present invention has good antiseptic properties and applicability, and is applied to the front and back surfaces or one surface of a work piece that is sandwiched between molds when the materials rub against each other. It may be applied to the mold side in some cases, and the use location is not particularly limited.
