Problems solved by technology

However, the basic component of the emulsion is water instead of oil. The viscosity of water is very low, which is not conducive to the formation of elastic fluid lubricating film, and the permeability of water is strong, and the corrosion and wear are large. Therefore, the extreme pressure of water-based emulsion is generally not as good as Oil-based cutting fluid

example 1

[0026] Weigh 528 grams of nonylphenol polyoxyethylene ether, put it into a three-necked bottle, cool it with a water bath, keep the temperature not higher than 40°C, add 28g of phosphorus pentoxide in batches under stirring, then raise the temperature to 70°C, and react After 2 hr, 506 g of yellow homogeneous liquid was obtained. 100 g of the liquid was mixed with 105 g of oleic acid diethanolamine, and reacted at 60° C. for 2 hours to obtain polyoxyethylene nonylphenol phosphate oleic acid diethanolamine salt A with a phosphorus content of 0.0018.

[0027] Take 10g of A and 20g of thiofatty acid ester extreme pressure agent B containing 15wt% sulfur, 13g of pentaerythritol rapeseed oleate C, 13g of hot poly cottonseed oil D, 30g of commercially available LZ5375 emulsifier F, and dilute with 7 # 14g of mechanical oil, a total of 100g was stirred at 60°C for 1hr to obtain a reddish-brown transparent emulsified oil concentrate G, its S / P gram atomic ratio was 160:1, and the tota...

example 2

[0029] Take 10 g of polyoxyethylene nonylphenol phosphate oleic acid diethanolamine salt A, 20 g of thiofatty acid ester extreme pressure agent B, and 30 g of emulsifier LZ5375 F in Example 1, stir and mix at 50 ° C for 1 hr to obtain 60 g of emulsified oil Concentrate H. Its S / P gram atomic ratio is 80: 1, does not contain oily agent and diluent oil, and the total amount of extreme pressure antiwear agent is 50%. Take concentrate H 12g, use 7 # Machine oil 8g is diluted, and diluent oil accounts for 40wt% of emulsified oil, obtains 20g transparent brown emulsified oil I after stirring evenly. Dilute I with water to make a 5wt% emulsion, and measure its P B The point is 735N (75kg), which meets the requirements of the SH0365-92 standard for the carrying capacity of extreme pressure emulsions.

example 3

[0031] 108g stearyl alcohol and 14g P 2 o 5 React at 100°C for 3 hours to obtain octadecyl phosphate (a mixture of mono- and di-esters). After filtering, it was neutralized with 30 g of triethanolamine to obtain alkyl phosphate triethanolamine salt A.

[0032] Get 1.5g A and 12.7g thiofatty acid ester B, 2.2g rapeseed oleic acid pentaerythritol ester C, 1.6g polymerized cottonseed oil D, 8g potassium ricinoleate, 65.8g emulsifier E (23.8g alkylbenzenesulfonic acid Sodium + 13g barium sulfonate + 17g triethanolamine oleate + 12g Siben-80) and 8.2g 7 # Machine oil is mixed to obtain emulsified oil concentrate J. Wherein the S / P gram atomic ratio is 30:1, and the total dosage of the extreme pressure antiwear agent and the oiliness agent is 23wt%. In the concentrate, the emulsifier accounts for 65.8wt%, and the diluent oil accounts for 8.2wt%. Take 10g of the concentrate J, add 5g of 150SN neutral oil to dilute and add water to make a 5% emulsion, and measure P B The value i...

Abstract

The concentrated composite extreme pressure anti-wear agent includes the following components: emulsifier in 20-80 wt%; at least one kind of sulfur-containing extreme pressure additive and at least one kind of phosphorus-containing extreme pressure additive with the gram atom S / P ratio 1-5000 in 10-80 wt%; oily agent in 0-60 wt% with the total content of extreme pressure additive and oily agent being 20-80 wt%; and diluent oil in 0-30 wt%. The emulsified liquid compounded with the concentrated agent has high lubricating effect, no toxicity, no bad smell, no bubble and other advantages, and may be used in metal cutting machining and metal deforming treatment.

Description

technical field [0001] The invention relates to an extreme pressure antiwear composition for metal cutting. technical background [0002] In the modern machinery manufacturing industry, cutting processing occupies a large proportion. In recent years, metalworking fluids have gradually developed from oil-based to water-based. Compared with cutting oil, emulsion has many obvious advantages, such as good water cooling effect, unlike cutting oil, it is not easy to cause oil mist to damage the health of workers, it is not easy to catch fire, safe and reliable, easy to maintain, and cheap. However, the basic component of the emulsion is water instead of oil. The viscosity of water is very low, which is not conducive to the formation of elastic fluid lubricating film, and the permeability of water is strong, and the corrosion and wear are large. Therefore, the extreme pressure of water-based emulsion is generally not as good as Oil-based cutting fluid. For emulsified oil without ...
