example 1

[0039] Example 1. ① Take 10g rosin, 2.2g oleic acid, 50g vegetable oil and 10g lard, stir and heat to 120°C, slowly add 30% sodium hydroxide dropwise to dissolve 7g, fully react and set aside; ②Take 12g triethanolamine and 21g Dehydrated ethanol, heated to 60°C, slowly added 20g of oleic acid, stirred for 20 minutes, added 32g of rapeseed oil and 16g of lard, stirred for 20 minutes for later use; ③mixed the liquid system obtained in steps ① and ②, stirred at 60°C After 20 minutes, cool to room temperature; ④Add 1.2g methyl silicone oil, 0.03g 2,6-di-tert-butyl-p-cresol, 7g absolute ethanol to the oil sample obtained in step ③, and stir until there is no precipitation to obtain the product .

example 2

[0040] Example 2. ①Take 6.8g rosin, 2g oleic acid, 20g vegetable oil and 11g lard, stir and heat to 110°C, slowly add 30% sodium hydroxide dropwise to dissolve 4g, fully react and set aside; ②Take 6g triethanolamine and 7gPE6400 , heated to 70°C, slowly added 10g of oleic acid, stirred for 20min, added 16g of rapeseed oil and 4g of lard, stirred for 20min and set aside; ③mixed the liquid system obtained in steps ① and ②, and stirred at 60°C for 20min, Cool to room temperature; ④Add 0.6g of methyl silicone oil, 0.01g of 2,6-di-tert-butyl-p-cresol, 4g of absolute ethanol to the oil sample obtained in step ③, and stir until there is no precipitation to obtain the product.

[0041] Each oil product in the embodiment is formulated into a 5% emulsion according to GB3142-82, and its oil film strength is measured on an MQ-800 type four-ball testing machine, and the results are shown in Table 1. It can be seen from Table 1 that the emulsion has certain extreme pressure and antiwear pro...

Abstract

The invention discloses biodegradable metal drawing lubricating oil, which comprises the following components in percentage by weight: 35 to 50 percent of colza oil, 7 to 25 percent of lard oil, 8 to 15 percent of oleic acid, 5 to 12 percent of rosin, 4 to 10 percent of triethanolamine, 3.5 to 8 percent of 30 percent NAOH solution, 6 to 12 percent of dilution, 3 to 6 percent of stabilizer, 0.5 to1 percent of defoaming agent and 0.01 to 0.06 percent of antioxidant. The method for producing the metal drawing lubricating oil comprises the following steps: reacting the rosin and the oleic acid with the 30 percent NAOH solution in the presence of the colza oil and the lard oil to obtain saponified solution (I); performing saponification reaction on the oleic acid and the triethanolamine in the presence of the dilution, and adding the colza oil and the lard oil to perform reaction to obtain saponified solution (II); and evenly mixing the saponified solution (I) and (II) and adding the stabilizer, the defoaming agent and the antioxidant into the mixed solution to obtain the drawing oil. The drawing oil has the advantages of reproducibility, good liquidity, excellent cleaning performance, good lubricating effect, high safety, environment protection, no pollution, no toxicity or harm of the product, capacity of meeting the emission standard after use and the like.

Description

1. Technical field [0001] The invention relates to a metal wire drawing lubricating oil and a preparation method thereof, in particular to a biodegradable metal wire drawing lubricating oil and a production method thereof. 2. Background technology [0002] As an important auxiliary material for metal forming, metal wire drawing lubricant mainly plays four roles of cooling, lubrication, cleaning and rust prevention in metal processing. At present, in the domestic market, oil-in-water emulsified coolant (drawing oil) is mostly used in the process of metal wire drawing, which contains a certain amount of mineral oil, is not easy to biodegrade, and will cause environmental pollution; and with the shortage of oil resources, it is necessary to Reduce the use of mineral base oils. At present, there has been some progress in the research on new wire drawing oil base oil in China. Guo Ziming used SN150 base oil and vegetable oil as a synthetic lubricating oil base to develop a high-...
