An environmentally friendly water-based aluminum foil stamping fluid

Abstract

The invention relates to the field of lubricating oil, in particular to an environment-friendly water-based aluminum foil stamping fluid. An environmentally friendly water-based aluminum foil stamping fluid, comprising the following components in mass percent: 0.05-0.5% lubricant, 0.5-5% wetting agent, 0.001-0.05% corrosion inhibitor, 0.05-0.1% rust inhibitor, pH regulator 0.2‑0.6%, and make up to 100% with distilled water. The preferred additives of the present invention are optimized and combined, and the obtained stamping fluid has excellent comprehensive properties. The formula system of the present invention provides mold protection for the stamping process, is a lubricant for aluminum foil stamping, has no VOC emissions, and greatly reduces the drying temperature to save energy. , the residue rate is low, and the residue has little effect on the thermal conductivity of aluminum fins, and can be removed with the self-cleaning of the air conditioner, that is, the 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.

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.
