Cleaning agent for clearing laser carving residue from plastic shell of intelligent mobile terminal and cleaning method

Abstract

The invention relates to a cleaning agent for clearing laser carving residue from a plastic shell of an intelligent mobile terminal. The cleaning agent is prepared from the following ingredients in percentage by mass: 10 to 30 percent of penetrating agents, 10 to 30 percent of corrosion inhibiters, 1 to 10 percent of surfactants, 1 to 20 percent of organic auxiliary agents, 1 to 10 percent of chelating agents and the balance water; the penetrating agents are one kind of substances or a mixture of more than two kinds of substances in the following substances of diethylene glycol monobutyl ether, diethylene glycol dimethyl ether, proprylene glycol monomethyl ether, glycerol, glycol, isopropanol, diglycol and ethanol; the corrosion inhibiters are one kind of substances or a mixture of more than two kinds of substances in the following substances of benzotriazole, sulfydryl phenylpropyl isothiazole, oleic imidamline, citric acid, tartaric acid, oxalic acid, boric acid, dodecyl succinic anhydride, hexanedioic acid, n-caprylic acid, neodecanoic acid, sebacic acid, dodecandioic acid and gluconic acid. The cleaning agent provided by the invention has the advantages that the residue cleaning speed is high; substrates, protection paint and color paint of the plastic shell of the intelligent mobile terminal cannot be corroded and dissolved; safety and environment protection are realized; the mass cleaning is easy.

Description

technical field [0001] The invention relates to a cleaning agent and a cleaning method for radium engraving residues on the plastic shell of an intelligent mobile terminal. Background technique [0002] Smart mobile terminals mainly refer to mobile devices or display devices such as smartphones and laptops. The processing process of their plastic shells is roughly as follows: the base material of the plastic shell (such as polycarbonate, etc.), the surface is electroplated, and a layer of metal is plated. , and then spray protective paint (such as acrylic resin paint, etc.) on the electroplated metal layer, then spray color paint (such as polyurethane resin paint, etc.) Paint (such as acrylic resin paint, etc.), after preliminary baking in an assembly line oven (80-85 ° C), and then laser engraving (that is, laser engraving) on ​​the plastic shell that has been baked and returned to normal temperature to carve various patterns and shapes, etc., and then clean the patterns a...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the existing strong polar organic solvents such as acetone to remove the radium engraving residues on the plastic shell of the intelligent mobile terminal through manual repeated wiping, which has strong physiological hazards to those who are in direct contact, and is harmful to The base material (such as polycarbonate, etc.) of the plastic shell of the smart mobile terminal has a strong dissolution and corrosion effect, low cleaning efficiency, cannot be mass-produced, and is prone to surface scratches, low product quality, and low yield. Provide a cleaning agent and cleaning method for removing radium engraving residues on plastic shells of smart mobile terminals. Resin paint, etc.) and color paint (such as polyurethane resin paint, etc.), safe and environmentally friendly, easy to clean in batches
