Environment-friendly water-based aluminum foil stamping liquid

Abstract

The invention relates to the field of lubricating oil, in particular to environment-friendly water-based aluminum foil stamping liquid which comprises, in weight percent, 0.05-0.5% of lubricants, 0.5-5% of wetting agents, 0.001-0.05% of corrosion inhibitors, 0.05-0.1% of antirust agents, 0.2-0.6% of pH (potential of hydrogen) regulators and distilled water supplemented to reach 100%. Optimized additives are optimally combined to obtain the stamping liquid with excellent comprehensive performances, a formula system provides a protective die for the stamping process, the stamping liquid is a lubricant for stamping an aluminum foil, VOC (volatile organic compounds) emission is avoided, drying temperature is greatly reduced, energy is saved, residual rate is low, and residues have slight influence on the heat-conducting property of aluminum fins and can be removed by self-cleaning of an air conditioner, namely, flushing of condensate water.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to an environment-friendly water-based aluminum foil stamping fluid. Background technique [0002] Aluminum fin heat exchanger is an important part of the heat exchange of the refrigeration system. Aluminum fins are manufactured by stamping aluminum (including aluminum alloy) foil. During the processing, it is necessary to apply a lubricant on the surface of the aluminum foil to ensure the processing of the aluminum fins and protect the mold. [0003] At present, the lubricating products used for aluminum fin stamping on the market are oil-based stamping oil. The shortcoming of oil-based stamping oil is that after stamping, stamping oil remains on the surface of the workpiece, which will affect the energy consumption of the whole machine and needs to be heated again. Tumble dry to remove residual oil from the surface. In the drying process, a higher temperature (140°C to 200°C) is ...

Problems solved by technology

[0003] At present, the lubricating products used for aluminum fin stamping on the market are oil-based stamping oil. The shortcoming of oil-based stamping oil is that after stamping, stamping oil remains on the surface of the workpiece, which will affect the energy consumption of the whole machine and needs to be heated again. Dry to remove residual oil on the surface

In the drying process, a higher temperature (140°C to 200°C) is required. The high-temperature oven consumes a lot of energy. The high-temperature volatilization of the oil increases the VOC (volatile organic content) in the atmosphere, which is not conducive to environmental protection. Based on these defects, there is a need for a new type of lubricant that can not only meet the processing requirements, but also reduce production energy consumption and improve the production environment in the processing of aluminum fins.
