Abstract

The invention discloses a metal surface dewaxing agent, and belongs to the field of metal surface treatment. A prepared solubilizing additive is a polymer with amphiprotic hydrophobic association prepared by emulsifying through the compounding of Span-80 and alkanolamide, and the grafted-copolymerization of acrylamide and 2-acryloylamino-2-methallyl sulfonate, and has high stability, corrosion resistance and an anti-static performance; an adhered waxy molecule is quickly dispersed in water by utilizing a hydrophilic group, so that the dewaxing efficiency is improved; a prepared adsorption corrosion-inhibition protection agent is added with benzyl chloride and epoxy chloropropane so as to carry out quaterisation, and a film can be quickly formed on ta metal surface by utilizing a good micelle assembling performance, so that a workpiece protection performance is improved; and an added dewaxing cleaning active agent is compounded by fatty alcohol polyoxyethylene ether and the like, and the solvent is used for solubilizing so as to accelerate the stripping speed, so that the dewaxing efficiency is improved, and a workpiece is protected. The metal surface dewaxing agent provided by theinvention solves the problems that a current dewaxing agent is low in dewaxing efficiency and easy to corrode the workpiece.

Description

technical field [0001] The invention belongs to the field of metal surface treatment, in particular to a metal surface wax remover. Background technique [0002] In recent years, with the continuous improvement of people's living standards and industrial technology, various metal products, electronics, precision industry and other products have been widely used in industrial production and people's daily life, and the market demand is also relatively large; various metal and Metal alloys have excellent physical and chemical properties and surface treatment characteristics, and are widely used. In order to improve their comprehensive performance, surface finish and decorative effect, surface finishing treatment must be carried out. Among them, mechanical polishing with special polishing wax is the first step in surface finishing treatment. Effective surface polishing process; for example, car glazing wax and polishing agent are used to protect, clean and polish the outer surf...
