Problems solved by technology

The advantages are high temperature resistance, high PD value, and good extreme pressure effect; the disadvantage is that chlorinated waste liquid is poisonous, and improper treatment will cause environmental problems, and free chloride ions can easily cause metal corrosion; organic sulfides have a strong smell and dark color. Severe corrosion to non-ferrous metals; phosphorus system is easy to rot and smell, and the pollution to the environment is self-evident

Embodiment 1

[0033] In this example, a high extreme pressure fully synthetic cutting fluid free of chlorine, sulfur and phosphorus is prepared according to the following steps:

[0034] Weigh 100kg of organic base triethanolamine and 50kg of 2,4,6-tris(aminocaproic acid)-1,3,5-triazine into the mixing tank, heat up to 50°C, stir for 120min to dissolve and become transparent, and then add 20kg of polymer ester LY-3586, 20kg of preservatives (1kg of paraben, 17kg of s-triazine, 2kg of sodium dehydroacetate) and 2kg of defoamer TL-56N, stirred for 20min, finally added 808kg of water, stirred for 90min, filtered Promptly obtain a kind of chlorine, sulfur, phosphorus high extreme pressure fully synthetic cutting fluid, 6% aqueous solution has 0 level of rust resistance, and 5% aqueous solution has a maximum non-jamming load of 38 kg.

Embodiment 2

[0036] In this example, a high extreme pressure fully synthetic cutting fluid free of chlorine, sulfur and phosphorus is prepared according to the following steps:

[0037] Weigh 250kg of organic base triethanolamine and 150kg of 2,4,6-tris(aminocaproyl)-1,3,5-triazine into the mixing tank, heat up to 50°C, stir for 120min to dissolve and become transparent, and then add 178kg polymer ester LY-3586, 100kg EO / PO block polyether 1740, 20kg preservative (1kg paraben, 17kg s-triazine, 2kg dehydroacetate sodium) and 2kg defoamer TL-56N, stirred for 20min, Finally, add 300kg of water, stir for 90 minutes, and filter to obtain a high extreme pressure fully synthetic cutting fluid that does not contain chlorine, sulfur, and phosphorus. The rust resistance of 1.5% aqueous solution is 0, and the maximum non-jamming load of 5% aqueous solution is 132kg.

Embodiment 3

[0039] In this example, a high extreme pressure fully synthetic cutting fluid free of chlorine, sulfur and phosphorus is prepared according to the following steps:

[0040] Weigh 250kg of organic base triethanolamine, 50kg of 2-butyloctanoic acid and 100kg of 2,4,6-tris(aminocaproic acid)-1,3,5-triazine and add them into the stirring and mixing kettle, heat up to 50°C, and stir 120min to dissolve and become transparent, then add 150kg of polyester LY-3586, 50kg of EO / PO block polyether 1740, 20kg of preservatives (1kg of paraben, 17kg of s-triazine, 2kg of sodium dehydroacetate), and 2kg of defoamer TL-56N, stir for 20 minutes, finally add 378kg of water by weight, stir for 90 minutes, and filter to get a high extreme pressure fully synthetic cutting fluid without chlorine, sulfur and phosphorus, 1.5% aqueous solution with grade 0 rust resistance, 5% aqueous solution The maximum non-jamming load is 109kg.

Abstract

The invention discloses a high extreme pressure fully synthetic cutting fluid free of chlorine, sulfur and phosphorus and a preparation method thereof. ‑1,3,5‑triazine, 2‑butyl octanoic acid, organic base, preservative and defoamer. The fully synthetic cutting fluid blended by the invention has excellent lubricating and extreme pressure properties, good anti-rust performance, stable product, long service life, long-term cycle use only by replenishing the original liquid, and no need to replace and discharge. It belongs to the green environmental protection cutting fluid and is suitable for various Suitable for low, medium and high load processing environment, it can meet the processing environment under high load conditions such as drilling, tapping and reaming of cast iron, carbon steel, stainless steel, aluminum alloy and other materials.

Description

technical field [0001] The invention belongs to the technical field of metal cutting processing and forming, and in particular relates to a metal processing fluid for metal cutting, processing, forming and other processes. Background technique [0002] With the development of metal cutting in the 21st century towards high speed, power and high precision, modern harsh processing conditions put forward higher and higher requirements for the quality of cutting fluid. Advanced manufacturing technologies such as CNC machine tools, machining centers and flexible manufacturing systems have been gradually popularized and applied, and advanced manufacturing technologies and cutting of difficult-to-machine materials are inseparable from cooling and lubrication technology; therefore, cutting fluids are becoming more and more important. Traditional oil-based cutting fluids have good lubricating performance, but poor cooling performance, making it difficult to adapt to harsh operating co...
