The invention discloses a copper gas welding solvent, relating to the technical field of welding solvent preparation. The copper gas welding solvent is characterized by comprising the following components by weight percent: 3-9% of rosin resin, 3-9% of surfactant, 2-6% of glutaric acid, 2-8% of ethyl acetate, 3-7% of zinc chloride, 1-5% of hydrochloric acid, 0.5-1.2% of triethanolamine, 3-8% of lauryl alcohol polyoxyethylene and excess water. The copper gas welding solvent disclosed by the invention has reasonable method, clear proportion, environmental protection and superior chemical activity.
Description
Technical field:
The present invention relates to welding volume preparing technical field, be specifically related to a kind of copper gas welding solvent and preparation method thereof.
Background technology:
Scaling powder is normally the mixture of main component with rosin, is the auxiliary material ensureing that welding process is carried out smoothly.Welding is the main processes in electronic assemblies, the auxiliary material used when scaling powder is welding, the Main Function of scaling powder is the oxide removing solder and welded mother metal surface, make the cleannes that metal surface reaches necessary. the oxidation again on surface when it prevents from welding, reduce solder surface tension, improving welding performance. the quality of scaling powder performance, directly has influence on the quality of electronic product.
And the flux that copper gas welding solvent is copper and copper alloy in the process of gas welding or soldering.
Summary of the invention:
Technical problem to be solved by this invention is to overcome that existing technological deficiency provides that a kind of method is reasonable, proportioning is clear, environmental protection, a kind of copper gas welding solvent that chemism is superior and preparation method thereof.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A kind of copper gas welding solvent, is characterized in that: the raw material comprising following percentage by weight,
Abietic resin 3-9%, surfactant 3-9%, glutaric acid 2-6%, ethyl acetate 2-8%, zinc chloride 3-7%, hydrochloric acid 1-5%, triethanolamine 0.5-1.2%, ethoxylated dodecyl alcohol 3-8%, surplus are water;
Described water is industrial demineralized water;
A preparation method for copper gas welding solvent, is characterized in that: comprise the following steps,
Step one, by weight percentage, zinc chloride, triethanolamine to be added to the water, fully to stir until dissolve completely;
Step 2, in step one gained solution in add ethoxylated dodecyl alcohol, ethyl acetate, fully stir until dissolve completely;
Step 3, in the solution of gained in step 2, add abietic resin, surfactant, fully stir until dissolve completely;
Step 4, in the solution of gained in step 3, add glutaric acid, hydrochloric acid, fully stir until dissolve completely.
Beneficial effect of the present invention is: the inventive method is reasonable, proportioning is clear, environmental protection, chemism are superior.
