Problems solved by technology

[0003] The main problems existing in the existing cutting fluid are: 1) Insufficient lubricating ability, it is difficult to meet the surface roughness requirements during valve finishing; 2) Insufficient antirust ability: after general cutting, the antirust period is less than one day, and another process must be done Anti-rust, which brings a lot of inconvenience to mass-produced valves; 3) Workers are prone to allergies; 4) To prevent mildew, many cutting fluids are added with phenolic substances, which are poisonous to the human body

Embodiment 1

[0026] An aqueous solution prepared by taking monoethanolamine benzoate as the main antirust agent, sodium alkylsulfonamide acetate as the main cutting lubricant, and adding other ingredients. The weight ratio of each raw material is: monoethanolamine benzoate: 1- 2.2%, disodium hydrogen phosphate: 0.2-0.8%, glycerol: 0.1-0.9%, sodium alkylsulfonamide acetate: 0.5-2.0%, polyethylene glycol with molecular weight 400-600: 0.1-0.5%, deionized Water 93.6-98.1%.

Embodiment 2

[0028] Take deionized water: 95.3-97.7%, monoethanolamine benzoate: 1.2-2%, disodium hydrogen phosphate: 0.3-0.7%, glycerol: 0.2-0.8%, sodium alkylsulfonamide acetate: 0.5-0.9%, Polyethylene glycol with a molecular weight of 400-600: 0.1-0.3% is prepared by stirring and mixing.

Embodiment 3

[0030] Deionized water: 96.5%, monoethanolamine benzoate: 1.6%, disodium hydrogen phosphate: 0.5%, glycerol: 0.5%, sodium alkylsulfonamide acetate: 0.7%, polyethylene glycol with molecular weight 400-600: 0.2% is prepared by stirring and mixing.

Abstract

The invention relates to rust-proof cutting fluid suitable for processing air valves, which is a water solution prepared by using monoethanolamine benzoate as a main rust-proof agent and sodium alkylsulfonylglycinate as a main cutting lubricant, and adding other ingredients. The weight ratios of the materials of the cutting solution are: 1-2.2% of monoethanolamine benzoate; 0.2-0.8% of sodium hydrogen phosphate; 0.1-0.9% of glycerin; 0.5-2.0% of sodium alkylsulfonylglycinate; 0.1-0.5% of polyethylene glycol with the molecular weight of 400-600; the balance of deionized water. The rust-proof cutting fluid suitable for processing the air valves can meet the cutting processing requirement and the rust-proof requirement of the air valve, and is safe and non-toxic.

Description

technical field [0001] The invention relates to a chemical solution composition used in metal cutting, in particular to a rust-proof cutting fluid suitable for valve processing. Background technique [0002] The valve is a key part of the engine, and it has special requirements for cutting fluid during processing: 1) The cutting fluid used can meet the surface roughness requirements during processing; 2) After cutting, the humidity is above 95% and the temperature is about 35°C 3) The cutting fluid is safe and non-toxic; no allergies to workers; 4) The cutting fluid is stable without decomposition and mildew. [0003] The main problems existing in the existing cutting fluid are: 1) Insufficient lubricating ability, it is difficult to meet the surface roughness requirements during valve finishing; 2) Insufficient antirust ability: after general cutting, the antirust period is less than one day, and another process must be done Anti-rust, which brings a lot of inconvenience t...
