Description

Rice straw raw oil

The present invention relates to a lubricating oil, and more particularly to a rice straw biomass lubricating oil blended with rice straw raw oil.

The traditional lubricating oil is mostly made by blending antifoaming agent, diffusing agent, antioxidant, cleaning agent, rust inhibitor, etc. in mineral oil, thereby applying the lubricating oil to steam and locomotive engines and All kinds of machinery to reduce friction and wear of the machine to achieve the purpose of extending the service life of the machine.

However, the main component of the traditional lubricating oil is mineral oil, and the mineral oil is mostly a petroleum derivative obtained by the distillation of the crude oil through the distillation and refining process, and retains a considerable viscosity, so the mineral oil can make the moving interface quite equivalent during operation. The oil film thickness does not collide, but also because the mineral oil has a considerable viscosity, so the friction coefficient of the traditional lubricating oil is obviously high; even under the long-term operation of the machine, it is easy to generate heat due to excessive friction of the machine. And the operating temperature of steam, locomotive engines or various machines is too high. In this way, not only the friction coefficient of the traditional lubricating oil is too high, but also the problems of wear of the organic parts and the improvement of the fuel consumption are likely to occur, and it is more likely that the mechanical parts are in a high-temperature operating environment for a long time, and the service life of the parts is reduced.

In addition, after the traditional lubricating oil is discarded, the mineral oil component contained in the conventional lubricating oil is dissolved, which easily leads to environmental pollution such as soil and water source, and seriously causes growth of plants, fish and shrimps and the like. Obstruction or even death. On the other hand, the various additives added in the conventional lubricating oil are mostly chemical compositions, and thus the additives are quite toxic. As a result, traditional lubricating oils tend to cause toxic substances to scatter in the air. In this way, if the user is exposed to toxic air for a long time, it may cause discomfort to the body and cause related diseases of the human body. What's more, due to the significant increase in the consumption of crude oil in recent years, and the process of crude oil combustion and refining, a large amount of carbon dioxide is emitted, which not only causes global warming effects, but even causes excessive exploitation of various fuels such as crude oil, which has been caused around the world. The panic of energy catastrophe.

In view of this, it is indeed necessary to develop a rice straw raw oil which can reduce the friction coefficient and reduce environmental pollution, to solve various problems arising from the operation of the conventional lubricating oil for the operation of the machine parts, and can be used as an alternative energy source.

The main object of the present invention is to improve the above disadvantages to provide a rice straw biomass lubricating oil which is capable of reducing the coefficient of friction to reduce fuel consumption of the machine and to reduce environmental pollution.

The second object of the present invention is to provide a rice straw biomass lubricating oil which is capable of reducing frictional heat generated by friction of a machine member to extend the service life of the machine.

Still another object of the present invention is to provide a rice straw biomass lubricating oil which is capable of increasing contact resistance to increase oil film thickness and reduce wear of the machine.

In order to attain the aforementioned object, the rice straw bio-based lubricating oil of the present invention comprises 74% by volume of mineral oil, 8% of rice straw oil and 18% of sorbitol oleate (Sorbitol).

Wherein the rice stem biomass oil is extracted from the rice straw, or the rice straw biomass oil is an oil produced by cracking the rice straw through a cracking device; the mineral oil is mineral oil, mechanical oil , white oil or paraffin oil.

The above and other objects, features, and advantages of the present invention will become more apparent from the claims. It is made up of 70~80% of mineral oil, 6~11% of rice straw raw oil and 14~20% of active agent. The mineral oil may be a common mineral oil, a mechanical oil, a white oil, a paraffin oil, etc.; the rice straw bio-oil is extracted from a rice straw, in particular, the rice straw is lysed through a cracking device. The oil produced by the rice straw raw oil is not the technical focus of the present invention, and will not be further described herein; the active agent may be any additive having a solubilizing effect, and the active agent of the present embodiment is preferably selected. It is sorbitol oleic acid (Sorbitol) for fully combining with the rice straw bio-oil, thereby increasing the mixing effect between the rice straw bio-oil and mineral oil.

According to the above, the rice straw raw lubricating oil of the present invention replaces the traditional mineral oil with a part of the rice straw raw oil, because the rice straw raw oil does not contain saturated aliphatic hydrocarbons (ie, aliphatic hydrocarbons) and unsaturated aliphatic hydrocarbons. Ingredients, the viscosity of the rice straw bio-oil is significantly lower than that of traditional mineral oil at high temperatures. In this way, compared with the traditional lubricating oil based on pure mineral oil, the rice straw raw oil of the present invention can effectively reduce the rice stalk due to the mixing of some rice straw raw oil, so that under high temperature operation. The friction coefficient of the lubricating oil has another characteristic of increasing the contact resistance and increasing the thickness of the oil film, thereby reducing the effect of long-term wear of the machine parts, and thereby increasing the output power of the machine. Even if the machine member is infiltrated by the low-friction coefficient rice straw bio-based lubricating oil of the invention, the heat generated by the friction of the machine member can be reduced, so that the steam, the locomotive engine or various machines are not long-term. It operates at high temperatures and can effectively extend the life of the machine.

In addition to the above, when the rice straw bio-based lubricating oil of the present invention is applied to steam, locomotive engines or various types of machinery, the fuel consumption can be effectively reduced, and the oil consumption and pollution can be reduced. In this way, not only can the damage caused by waste lubricating oil to the environment such as water source, soil or air be reduced, but also the over-exploitation of crude oil can be slowed down at the same time to achieve environmental protection and energy saving.

In order to further confirm that the rice straw biomass lubricating oil of the present invention has the above-mentioned effects, the present embodiment preferably selects 74% of mineral oil mixed with 8% of rice straw raw oil and 18% of sorbitol oleic acid fat. The viscosity values of the rice straw biomass lubricating oil of the present invention are as shown in Table 1. The results show that the addition of the rice straw bio-oil can effectively improve the viscosity of the lubricating oil after mixing, and maintain the better lubricating effect under low temperature and high temperature.

Here, in this embodiment, a parallel type abrasion tester [ring and block] is used for the abrasion test, thereby observing the friction coefficient of the conventional lubricating oil and the rice straw raw lubricating oil of the present invention under the same load and different rotation speeds. , contact resistance and test piece temperature.

Please refer to the figures 1~3 for the friction coefficient, contact resistance and test piece measured under the load of 60N and 80rpm [0.14m/s] for conventional lubricating oil and rice straw raw oil. temperature. As shown in the first graph, when the load is increased to 60N, the contact resistance value of the rice straw raw oil of the present invention [curve a shown in the figure] is significantly higher than that of the conventional lubricating oil (as shown in the figure). Curve b] also represents the generation of the rice straw bio-lubricant of the present invention The oil film thickness is greater than the oil film thickness of the traditional lubricating oil, so it can effectively reduce the wear of the machine during operation; in addition, as shown in Figures 2 and 3, although the friction coefficient of the traditional mineral oil [the curve shown in the figure b) decreases with time and can gradually decrease from 0.32 to 0.17, but the length of time is always higher than the friction coefficient of the rice straw raw oil of the present invention [curve a shown in the figure]; According to the results of Fig. 3, in the case where the friction coefficient is relatively small, the temperature of the workpiece using the rice straw bio-lubricant of the present invention (the curve a shown in the figure) is significantly lower than that of the conventional lubricating oil. Piece temperature [curve b as shown in the figure]. Thereby, it can be confirmed that the rice straw raw lubricating oil of the invention can effectively reduce the heat generated when the machine parts are rubbed, and achieve the effect of prolonging the service life of the machine.

In addition to the above, please refer to Figure 4 below for the traditional lubricating oil and rice straw bio-lubricating oil under the load of 60N, the rotation speed is measured under 160rpm [0.27m / s] shown in Figure 4 The obtained friction coefficient, contact resistance and test piece temperature. Wherein, the curve a1 shown in the figure is the contact resistance of the rice straw raw lubricating oil of the present invention, and the curve b1 is the contact resistance of the conventional lubricating oil; the curve a2 shown in the figure is the rice straw raw lubricating oil of the present invention. The friction coefficient, curve b2 is the friction coefficient of the conventional lubricating oil; the curve a3 shown in the figure is the test piece temperature of the rice straw raw lubricating oil of the present invention, and the curve b3 is the test piece temperature of the conventional lubricating oil. The results show that under the different rotational speeds shown in Fig. 4, the friction coefficient, contact resistance and test piece temperature of the conventional mineral oil and the rice straw raw lubricating oil of the present invention all have the same tendency as described above.

The invention is further compared with other embodiments, so as to show that the conventional lubricating oil and the rice straw raw lubricating oil are under a load of 60 N and a rotational speed of 80 rpm [0.14 m/s] as shown in the fifth and sixth figures. Separate test piece temperature and friction system number. Wherein, the rice straw raw lubricating oil of the invention has different composition ratios, for example, A1 is a rice straw raw lubricating oil containing 74% mineral oil, 6% rice straw raw oil and 20% active agent; A2 is containing 74% mineral oil, 8% rice straw oil and 18% active agent of rice straw raw oil; A3 is rice stem biomass containing 74% mineral oil, 10% rice straw oil and 16% active agent Lubricating oil; B is a traditional mineral oil without added rice straw raw oil.

Referring to Figures 5 and 6, the rice straw bio-lubricant added with 10% rice straw bio-oil has a better contact resistance value, but it also increases its friction coefficient, which leads to an increase in the temperature of the test piece. .

That is to say, when the test results of Figures 5 and 6 are combined and theoretically added with more rice straw bio-oil, the expected coefficient of friction coefficient and specimen temperature should be better than the conventional ones; However, it was found that the addition of 10% rice straw oil was similar to the addition of 6% rice straw oil, and it was surprisingly effective only when adding 8% rice straw oil.

Therefore, when the rice straw bio-oil is added by about 8% (that is, A2 contains 74% mineral oil, 8% rice straw oil and 18% active agent of rice straw raw oil), the contact resistance is not only relative. Higher than traditional mineral oil, and the measured friction coefficient is significantly lower; in the case where the friction coefficient is relatively small, the temperature of the test piece measured as shown in Fig. 5 is obviously lower than that of the conventional lubricating oil. The temperature of the test piece is used to reduce the frictional heat of the machine to achieve the effect of extending the service life of the machine.

As described above, the rice straw bio-based lubricating oil of the present invention can effectively reduce the friction coefficient, thereby improving the output power of the machine and achieving the effect of reducing the fuel consumption of the machine. At the same time, the rice straw raw material lubricating oil of the invention can also reduce the friction heat generated by the friction of the machine parts, so as to extend the service life of the machine parts. effect. In addition, the rice straw bio-based lubricating oil of the invention can effectively increase the contact resistance value to increase the thickness of the oil film and reduce the wear of the machine during operation.
