Abstract

The invention relates to high-performance volatile fin punching oil, which consists of isoparaffin base oil, a surfactant, an acid trapping agent, an oiliness agent, an extreme pressure anti-wear agent, a defoaming agent and an antirust agent. The invention further provides a preparation method of the fin stamping oil. According to the invention, the excellent lubricity of the fin during processing is ensured, the fin has a certain flash point, the safety of the fin is ensured, and a processed part can be completely volatilized at room temperature within a short time without being heated and baked, so that no residue is left. The high-performance volatile fin punching oil does not contain water, chlorine, sulfur and other corrosives, and does not corrode or rust various metal materials. The pH value of the working solution prepared from isoparaffin is 6.5-7.0, and the product waste liquid is also neutral, does not cause anaphylactic reaction to skin, does not generate acidification reaction, does not have heavy metal ions, has good biodegradability and completely meets the environmental protection requirements.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to fin stamping oil, in particular to a high-performance volatile fin stamping oil and a preparation method thereof. Background technique [0002] Fin stamping oil is a special precision stamping oil for the air-conditioning industry. The precision stamping oil is a special lubricating oil for stamping aluminum fins of air conditioners and evaporators and for copper tube expansion and bending. The production process has extremely high requirements for its lubricity, safety, volatility and corrosion resistance. . The product should have suitable lubricity and low temperature performance, which can improve the stamping quality of the workpiece, effectively protect the mold, can be completely volatilized, has no residue, is non-toxic and tasteless, harmless to the human body, and has no corrosion to non-ferrous metals such as copper and aluminum. [0003] In the situation of shortage...
