Description

Whole-mass coffee lubricant

The present invention relates to a whole coffee coffee lubricating oil, in particular to a whole coffee coffee lubricating oil which can effectively reduce the mechanical friction coefficient and the operating temperature, and can replace mineral oil.

Traditional lubricating oils contain base oils and additives. Among them, base oils use mineral oil as the bulk, while additives can contain anti-foaming agents, diffusing agents, antioxidants, cleaning agents or rust inhibitors. Traditional lubricating oils are mainly used To lubricate steam, locomotive engines and various types of machinery, reduce the wear of machine parts and reduce the frequency of machine parts replacement. Derivatives obtained by distillation and refining of crude oil of mineral oil series, the main component of which is hydrocarbons, has considerable viscosity, which can make the moving interface of the machine produce an oil film thickness during operation to protect the machine from wear, but Also because of the viscosity of mineral oil, the friction coefficient of traditional lubricating oil is increased, which causes the operating temperature to be too high under long-term friction of the machine parts. When the machine parts are exposed to a high temperature environment for a long time, the wear and the service life of the machine parts are reduced. Since mineral oil is extracted from crude oil, however, due to the increasing population of the planet today, crude oil is gradually depleting due to over-exploitation, and the process of refining crude oil will inevitably emit a large amount of carbon dioxide, which will promote the deterioration of the global greenhouse effect , And affect the earth’s ecological environment and climate. However, traditional mineral oil has the problems of "high coefficient of friction" and "destruction of the environment". In view of this, it is necessary to develop technology that can solve the above-mentioned conventional shortcomings.

The purpose of the present invention is to provide a whole-mass coffee lubricant, which has the advantages of effectively reducing the mechanical friction coefficient and operating temperature, and can replace mineral oil. In particular, the problem to be solved by the present invention is that the traditional mineral oil has a "high coefficient of friction" and "destruction of the environment". The technical means to solve the above problem is to provide a whole-mass coffee lubricant, which includes: 37% to 40% by weight of glycerin; 1% to 5% by weight of gum arabic; and the rest is coffee raw oil. The above objects and advantages of the present invention are not difficult to gain an in-depth understanding from the following detailed description and drawings of selected embodiments. The following examples and drawings are used to explain the present invention in detail:

In practice, the weight percentages of the coffee crude oil, glycerin and gum arabic can be 58.8wt%, 39.2wt% and 2.0wt%, respectively. Alternatively, the weight percentages of the coffee crude oil, glycerin and gum arabic may be 57.5wt%, 38.3wt% and 4.2wt%, respectively. In addition, the viscosity of the coffee raw oil at 40°C is 60 to 70 cSt. Please refer to Table 1 below, which is the detailed composition of the ratio of two coffee oils in the whole-body coffee lubricant (or coffee oil for short) in this case. Table 1

After conversion, Table 1 can be converted into detailed components by weight, as shown in Table 2. Table 2

Regarding the blending method of this case: (1) Control the room temperature at 25°C, take out the coffee ground oil (ie the coffee crude oil in this case) and filter to reach the required weight. (2) Add surfactant to coffee ground oil and stir. (3) Add glycerin to the surfactant (the gum arabic in this case) and stir it with coffee ground oil. (4) Finally, the crude coffee lubricating oil is heated to 80°C and stirred. (5) After cooling, measure whether the viscosity reaches the required viscosity at 40℃ (for example, it can be maintained at 60~70cSt). (6) If the desired viscosity is not reached, go back to step (4). Repeat the same steps until the desired viscosity is reached. The experimental method in this case is to use the abrasion tester to make ring and block (Ring on Disk) line contact movement for the test. During the operation, according to a specific load (such as 60N) and a specific speed (such as 80rpm), record a variety of different operating conditions Parameters such as friction coefficient, temperature of test piece, etc Please refer to the first figure, which shows the measured data of the wear coefficients of traditional mineral oil and two different ratios of whole-mass coffee lubricants in this case. Among them, the horizontal axis in Figure 1 is time, and the vertical axis is the wear coefficient. L0 represents the data curve of the traditional mineral oil, and L1 and L2 represent the data curves of the coffee oil ratios (1) and (2) in this case. It can be proved from Figure 1 that after about 15 minutes, the friction coefficient of the coffee oil ratio (1) and (2) in this case is lower (at least 50% lower) than the traditional mineral oil, especially the coffee oil ratio (2) Optimal. Please refer to Fig. 2, which shows the measured data of the temperature of traditional mineral oil and two different ratios of whole-mass coffee lubricant in this case. Among them, the horizontal axis in Figure 2 is time, and the vertical axis is temperature. M0 represents the data curve of the traditional mineral oil, and M1 and M2 represent the data curves of the coffee oil ratios (1) and (2) in this case. It can be proved from Figure 2 that after about 15 minutes, the temperature of the coffee oil ratios (1) and (2) in this case is lower (at least 1°C lower) than that of traditional mineral oil. As mentioned above, the whole-body coffee lubricating oil of the present invention can effectively reduce the friction coefficient during operation, and can reduce the heat generated by the friction of the machine parts, thereby delaying the service life of the machine parts. Furthermore, the whole-life coffee lubricating oil of the present invention can replace mineral oil, thereby slowing down the excessive exploitation of crude oil, and reducing the extraction of crude oil, so as to achieve the effects of replacing mineral oil and reducing air pollution.
