Problems solved by technology

Smoke is very harmful to the human body. In addition to the chemical composition of the smoke itself causing harm to people, its main hazard is that the smoke is generated and moves very quickly, usually much faster than the flame propagation speed; and a large amount of smoke makes people look directly The distance is shortened, the visibility is reduced, and people lose their direction and cannot escape and rescue under fire conditions, which seriously threatens the safety of life and property.

Embodiment 1

[0015] In order to investigate the influence of different catalysts on toluenesulfonic acid and ionic liquid catalyst D-96 on the reaction conversion rate, under the same conditions of raw material quality, reaction temperature, reaction time and molar ratio, the reaction conversion rate was compared, as follows:

[0016] First, add boric acid and glycerin into the reactor at a molar ratio of 1:2, and react at 130°C for 4 hours to obtain light yellow boric acid diglyceride; then add boric acid diglyceride and oleic acid into the reactor at a molar ratio of 1:1 , and then add the catalyst, vacuumize, rise to the set temperature and react for 3.5 hours, and the oil mist and smoke suppressing lubricating ester can be obtained.

[0017] At the same time, according to the same reaction conditions as above, the influence of different ionic liquid catalyst D-96 additions on the reaction conversion rate was compared.

[0018] The experimental results are shown in Table 1 and Table 2, ...

Embodiment 2

[0028] This embodiment synthesizes the oil mist smoke suppressing lubricating ester according to the following steps:

[0029] Weigh 62g of boric acid and 184g of glycerin into a three-necked flat-bottomed flask, heat up to 130°C, react for 4 hours, condense to remove 36g of by-product water, and obtain 210g of boric acid diglyceride; add 282g of oleic acid and 2.46g of catalyst to boric acid diglyceride D-96, evacuate to P=-0.06MP, raise the temperature to 135°C, and react for 3.5 hours to obtain oil mist suppressing smoke lubricating ester with an acid value of 0.8mgKOH / g.

[0030] Carry out the following lubricity experiments on the oil mist suppressing smoke lubricating ester obtained in this example, and compare it with other several esters (chlorinated paraffin s-52, triisopropylphenyl phosphate IPPP, vulcanized lard) at the same time:

[0031] Wear test: The model of the four-ball machine used is MS-10J (made in Xiamen), the speed is 1200r / min, the diameter of the steel...

Abstract

The invention discloses a synthesis method of oil mist smoke suppression lubricating grease and application of the oil mist smoke suppression lubricating grease in cold heading oil and hole enlargement oil. The synthesis method is characterized by comprising the steps of firstly, synthesizing diglyceride borate by taking boric acid and glycerol as raw materials; after that, adding oleic acid or heavy alkylbenzene sulfonic acid and an ionic liquid catalyst D-96 into the diglyceride borate for carrying out a reaction to obtain the oil mist smoke suppression lubricating grease. After the oil mist smoke suppression lubricating grease is added into the cold heading oil or the hole enlargement oil as a raw material, the lubricating performance and wear resistance of the cold heading oil or the hole enlargement oil are improved, and the smoke generation amount of the cold heading oil or the hole enlargement oil is reduced.

Description

technical field [0001] The invention relates to a method for synthesizing oil mist and smoke suppressing lubricating ester and its application in cold heading oil and diameter expanding oil. Background technique [0002] The working process of metal processing lubricants determines that its oil mist generation forms include mechanical, physical and physical-chemical methods. In order to effectively lubricate, resist oil mist and eliminate smoke, metal processing lubricants have to go through the process of pump circulation, spray, jet, violent impact with high-speed rotating tools and high-temperature evaporation during use. Smoke is a kind of sol formed by the suspension of solid and liquid small particles in the air when polymer materials are thermally decomposed or incompletely burned. Smoke is very harmful to the human body. In addition to the poisonous chemical composition of the smoke itself, its main hazard lies in the fact that the smoke is generated and moved very ...
