Problems solved by technology

Due to the existence of water on the surface of the copper material during use, it is very easy to cause corrosion and discoloration on the surface of the copper strip. At the same time, because the emulsification and dispersion of some components are not easy to stabilize, the annealing and volatilization after rolling is not complete, and stains are easy to remain on the surface of the strip, which affects the product. Quality; components that are corrosive to the strip in the traditional emulsion formula, such as: oleic acid, triethanolamine, etc.

specific Embodiment approach 2

[0020] When rolling the copper grade in the middle is H65, when the batch number 5066011 brass strip, its entrance thickness is 1.8mm, and the exit thickness is 0.6mm, which is completed in 5 rolling passes; for this purpose, prepare 1000 kg of emulsion. First prepare the emulsified oil by adding 10% of 32# general machine tool hydraulic oil to the container, then add 70% of 7# mechanical oil, 5% of sodium petroleum sulfonate, 10% of O-10 emulsifier, 5% of For 7# industrial white oil, use a stirrer to stir continuously and use an electric heater to control the temperature during the preparation. The stirring time is 60 minutes, and the heating temperature is 50°C. Then add the prepared emulsified oil to 90% deionized water based on the total amount of the emulsion, use a stirrer to continuously stir and dilute during the preparation, and insert an electric heater for temperature-controlled heating. The stirring time is 240 minutes, and the heating temperature at 50°C, and fina...

Abstract

The invention provides a method for preparing emulsion for rolling copper and copper alloy, wherein the emulsified oil is prepared mainly from universal machine hydraulic-oil 10-20%, machinery oil 50-70%, sodium sulfonate of petrodeum 5-10%, 0-10 emulsifying agent 10-20%, industrial white oil 5-10% through mixing, heating, mixing, charging into 90-97% deionized water, stirring and diluting.

Description

Technical field: [0001] The invention relates to the technical field of nonferrous metal processing lubrication, and relates to a method for preparing an emulsion for rolling copper and copper alloys. technical background: [0002] At present, there is no unified standard for the use of rolling emulsion in copper processing enterprises across the country, and there is no ready-made emulsion for selection. Due to the small demand for rolling emulsion, there is no professional emulsion production enterprise in China, and there is only one emulsion blending enterprise. Most copper processing enterprises prepare emulsions by themselves, but the performance is unstable, which is harmful to production and products. Quality has a big impact. [0003] Abroad: Esso-Mobil is the main manufacturer specializing in the production of rolling oil. The company's oil products have good process characteristics and enjoy high prestige in the world, but the price is as high as 35,800 yuan / ton...
