Abstract

The invention discloses a neutral low-foam environment-friendly dewaxing solution and a preparation method thereof. The total mass of the dewaxing solution is 100%, and the dewaxing solution comprises, by mass percentage, 18-23% of surfactant, 1-4% of a chelating agent, 0.5-1% of a dispersing agent, 1-3% of a corrosion inhibitor and the balance water. According to the neutral low-foam environment-friendly dewaxing solution and the preparation method thereof, the surfactant, the chelating agent, the dispersing agent and the corrosion inhibitor are combined, so that the neutral environment-friendly low-foam dewaxing solution containing no substances such as alkyl phenol ethoxylates (APEO) is obtained; the environment and a water source cannot be polluted; and the good cleaning and descalingeffect is achieved for metal workpieces.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment agents, in particular to a neutral low-foaming environmental wax removal water and a preparation method thereof. Background technique [0002] Wax removal is the first process of pre-treatment of metal electroplating parts. The speed and thoroughness of wax removal are of great significance to the electroplating production line. Therefore, choosing a good wax remover can improve the wax removal performance and bring good economic benefits. [0003] The wax scale of polishing wax is mainly composed of paraffin wax, fatty acid, rosin soap, metal oxide and certain inorganic solid polishing particles such as: corundum, silicon carbide, high alumina porcelain, etc. The solid particles are mainly evenly distributed in the polishing wax system in the form of powder, as well as some grinding cloth remnants, the powder of the polished metal matrix and its oxides. The wax scale and the wor...
