Concentrated wax removing solution convenient for wax separation, and preparation method thereof

Abstract

The invention discloses a concentrated wax removing solution convenient for wax separation, and a preparation method thereof, and belongs to the field of metal washing agent. The concentrated wax removing solution convenient for wax separation comprises, by weight, 1 to 3 parts of modified MOFs, 7.5 to 8 parts of nonylphenol polyoxyethylene ether; 15 to 16 parts of coconutt diethanol amide; 2.5 to3 parts of glycerol; 0.5 to 1 part of polyethylene glycol; 9 to 10 parts of diethylenetriamine; and 40 to 50 parts of anhydrous ethanol; wherein the modified MOFs comprises MOFs and expanded graphitein MOFs channels and pores. The concentrated wax removing solution is capable of simplifying wax removing solution post-treatment step.

Description

technical field [0001] The invention relates to the field of metal detergents, more specifically, it relates to a concentrated wax-removing water which is convenient for wax separation and a preparation method thereof. Background technique [0002] After metal workpieces (such as mobile phone back shells) are mechanically polished, a large amount of waxy polishing powder adherents will remain on the surface. These adherents are mainly composed of paraffin wax, fatty acids, rosin soap, metal oxides and certain inorganic solid polishing particles These wax deposits need to be thoroughly cleaned before leaving the factory or proceeding to the next step of processing. The existing treatment method is generally to put the workpiece into the wax-removing water and let it stand still, and cooperate with ultrasonic waves or stirring to melt the waxy adherents from the surface of the workpiece into the wax-removing water. [0003] In the Chinese invention patent whose notification n...

Problems solved by technology

However, due to the use of such emulsifier-containing dewaxing water, the oil mixture such as paraffin and fatty acids in the waxy adherents is suspended in the dewaxing water and cannot completely float to the surface of the dewaxing water, making the dewaxing It is difficult to separate waxy water from oil mixtures such as paraffin wax and fatty acids. Subsequent separation needs to increase multiple processes, which is not only very troublesome to handle, but also increases the processing cost
