Embodiment 1

[0019] Weigh 40g of biodiesel, 4.4g of Span80, 5.6g of Tween80, and 50g of water prepared from waste oil by immobilized enzyme method, mix the biodiesel with the nonionic surfactant composed of Span80 and Tween80, add it to the reactor and heat To 60°C, under the condition of constant stirring, water was gradually added dropwise into the reactor at a rate of 3ml / min to make a mixed solution, the mixed solution was naturally cooled to room temperature, and the biodiesel nanoemulsion was obtained by standing at room temperature.

[0020] The performance of the prepared biodiesel nanoemulsion was evaluated according to the following methods:

[0021] 1. Long-term stability:

[0022] The biodiesel nanoemulsion prepared by the present invention is left to stand for half a year, and the appearance is observed. If the emulsion does not appear clear delamination, it shows that the biodiesel nanoemulsion has good long-term stability.

[0023] 2. Particle size distribution measurement:...

Embodiment 2

[0041] Weigh 13.3g of biodiesel produced from gutter oil by immobilized enzyme method, 2.68g of Span80, 4.02g of Tween80 and 80g of water. Mix biodiesel with non-ionic surfactants composed of Span80 and Tween80, add it into the reactor and heat it to 60°C, and gradually add water into the reactor dropwise at a rate of 3ml / min under constant stirring to prepare to form a mixed solution, naturally cool the mixed solution to room temperature, and let stand at room temperature to obtain biodiesel nanoemulsion.

[0042] Detected by the method described in Example 1, the results are shown in Table 2.

Embodiment 3

[0046] Weigh 5g of biodiesel produced from gutter oil by immobilized enzyme method, 2.2g of Span80, 2.8g of Tween80 and 90g of water. Mix the biodiesel with the non-ionic surfactant composed of Span80 and Tween80, add it into the reactor and heat it to 60°C, under the condition of constant stirring, water is gradually added dropwise into the reactor at a rate of 3ml / min, A mixed liquid is prepared, the mixed liquid is naturally cooled to room temperature, and left standing at room temperature to obtain the biodiesel nanoemulsion.

[0047] Detected by the method described in Example 1, the results are shown in Table 3.

Abstract

The invention relates to a biodiesel nano-emulsion as well as a preparation method and application thereof. The biodiesel nano-emulsion comprises the following components in parts by weight: 5-40 parts of biodiesel, 5-25 parts of a nonionic surfactant and the balance of water based on the total amount of the components is 100 parts by weight. The biodiesel nano-emulsion disclosed by the invention is uniform in particle size distribution, has very good long-term stability, does not have changes of appearance after being placed for more than a half year, does not have obvious demixing and sedimentation phenomena, accords with environmental protection and various industrial requirements, and is easy to transport. The biodiesel nano-emulsion disclosed by the invention can be used as a lubricant for drilling fluid, and provides a new direction for the development of hogwash oil.

Description

technical field [0001] The invention relates to a biodiesel nanoemulsion, its preparation method and its application. Background technique [0002] At present, the development and application of biodiesel in my country is subject to many restrictions due to constraints such as high production costs, shortage of raw materials, and difficult breakthroughs in key technologies. In particular, the application of biodiesel in the drilling fluid field is subject to many restrictions. [0003] Therefore, there is a need for a biodiesel-containing product that is manufactured at low cost and is effectively used in the field of drilling fluids. Contents of the invention [0004] The purpose of the present invention is to provide a biodiesel nanoemulsion. [0005] Another object of the present invention is to provide a method for preparing biodiesel nanoemulsion. [0006] Another object of the present invention is to provide the use of the biodiesel nanoemulsion as a lubricant for...
