preparation example Construction

[0053] The preparation method of the lubricating grease of one embodiment is one of the preparation methods of the above-mentioned lubricating grease, comprising the steps of:

[0054] Under the condition of 70°C to 80°C, base oil, thickener and polymetallic oxygen cluster compound are mixed to obtain lubricating grease.

[0055] Wherein, the base oil includes biological oil and synthetic oil, and the mass fraction of the base oil is 77-92 parts. Further, the mass fraction of bio-oil is 60-70 parts; the mass fraction of synthetic oil is 17-22 fractions.

[0056] Further, bio-oil includes vegetable oil and animal oil. Furthermore, the vegetable oil is selected from at least one of castor oil, sunflower oil and soybean oil; the animal oil is selected from at least one of tallow, lard and sheep oil. Specifically, the mass parts of vegetable oil are 30-35 parts; the mass parts of animal oil are 30-35 parts. Wherein, castor oil, sunflower oil and soybean oil are all liquid, tall...

Embodiment 1

[0074] The preparation steps of the grease of the present embodiment are as follows:

[0075] (1) In parts by mass, 30 parts of castor oil, 30 parts of tallow, 9 parts of neopentyl glycol ester and 8 parts of pentaerythritol ester are mixed evenly, added to the reaction kettle, and 5 parts of polymetallic oxygen clusters are added in turn Compound, 4 parts of sebacic acid, 2 parts of salicylic acid, 0.3 part of alum and 3 parts of 12-hydroxylithium stearate, and then the reaction kettle was heated to 70°C and stirred at a speed of 50r / min for 30min to obtain a premixed things.

[0076] (2) In parts by mass, 1 part of sodium hydroxide is dissolved in 1 part of soapy water to obtain an alkaline solution; the alkaline solution and the premix are added to the reactor and mixed evenly, and then the reactor is heated and pressurized Saponify at 170°C and 0.5Mpa for 70min at constant pressure, then dehydrate at constant pressure for 20min, dehydrate for 10min while degassing, and co...

Embodiment 2

[0079] The preparation steps of the grease of the present embodiment are as follows:

[0080] (1) In terms of parts by mass, 32 parts of castor oil, 32 parts of tallow, 10 parts of neopentyl glycol ester and 9 parts of pentaerythritol ester are mixed uniformly, added to the reaction kettle, and 6 parts of polymetallic oxygen clusters are sequentially added compound, 5 parts of sebacic acid, 3 parts of salicylic acid, 0.5 part of alum and 4 parts of 12-hydroxylithium stearate, and then the reaction kettle was heated to 75°C and stirred at a speed of 55r / min for 35min to obtain a premixed things.

[0081] (2) In terms of parts by mass, 1 part of sodium hydroxide is dissolved in 1 part of soapy water to obtain an alkaline solution; the alkaline solution is added to the reactor and mixed with the premix evenly, and then the reactor is heated and pressurized Saponify at 175°C and 0.6Mpa for 75min at constant pressure, then dehydrate at constant pressure for 25min, dehydrate for 12...

Abstract

The invention relates to lubricating grease and a preparation method thereof. The lubricating grease is prepared from the following raw materials in parts by mass: 77-92 parts of base oil, 10.3-17.6 parts of a thickening agent and 5-8 parts of a polyoxometalate compound, wherein the base oil comprises bio-oil and synthetic oil, and the polyoxometalate compound has a nucleophilic group and an electrophilic group. Through the synergistic effect of the base oil and the polyoxometalate compound, the lubricating grease has better adsorbability to micron-sized steel scraps.

Description

technical field [0001] The invention relates to the technical field of lubrication, in particular to a lubricating grease and a preparation method thereof. Background technique [0002] Due to the long-term use of the mechanical equipment used in the camera module processing, the friction between the manipulator and the parts will produce micron-sized fine steel debris (SUS), which will enter the camera module during the loading process of the camera components. Interference with the optical imaging of the module directly affects the imaging quality of the module. [0003] In order to avoid steel scraps from mechanical equipment, regular maintenance is generally carried out on the equipment, and surface treatment such as lubrication is carried out on mechanical parts. However, the current lubricating grease has poor adsorption to micron-sized steel chips, which affects the production yield and efficiency of the product. Contents of the invention [0004] Based on this, i...
