Abstract
The invention relates to chemical paint, in particular to a soldering anti-spattering liquid which can prevent a solder ball formed by spattering from being adhered to a soldered product in soldering. The soldering anti-spattering liquid consists of the following raw materials according to the weight ratio: the weight ratio of water to calcium oxide to ink with concentration of 1 percent is equal to 100.0 to 20.0-30.0 to 0.5-1.0. Therefore, the soldering anti-spattering liquid has good erasable property, and is easy to remove the solder ball formed in soldering; in addition, the soldering anti-spattering liquid does not need other cleaning reagents to remove the trace remained by spattered liquid, produces small smog and is favorable for physical health of operators.
Description
Technical field
The present invention relates to a kind of chemical coating, the solder ball that forms of preventing from during specifically a kind of the welding to splash adheres to the welding splash-proof solution on the soldered product.
Background technology
Welding is by heating or pressurization or both and usefulness, uses or does not use filler metal, makes a kind of method for metal working that is reached interatomic bond by the weldering metal.Splashing is common bad phenomenon of when welding, during welding operation, solvent boiling, spark splash everywhere, drop on the weld seam both sides, the cooling back forms irregular solder ball, adhere to product surface, need the polishing cleaning, labour intensity is big, it is low to imitate rule, particularly drop on irregular product surface, it is all very bothersome to polish, and also influences the postwelding operation.The shortcoming that in the market welding splash-proof solution exists has: though the solder ball that forms that splashes after using is removed easily, the welder can feel that peculiar smell is arranged, boils in water for a while, then dress with soy, vinegar, etc. eye in the operating process, oil smoke is big, unhealthful; Anti sling liquid generally is spray, is applied to product surface, and contain multiple harmful element in this liquid in use, not only product surface is impacted, and the difficult removing of self vestige, to use a large amount of lacquers to remove residual anti sling liquid before the lacquer, the waste material with thinner (solvent or diluent); Influence next step and spray paint, the sticking power of lacquer is relatively poor, if anti sling liquid is not removed thoroughly, that lacquer back lacquer table easily produces is wrinkling, depainting, return the wet goods phenomenon.
Summary of the invention
In order to overcome above-mentioned technological deficiency, the invention provides a kind of welding splash-proof solution, erasability is good, the splash that forms when not only removing welding easily, and do not need other cleaning reagent to remove the residue of sling liquid on workpiece; Generation smog is little, helps the healthy of operative employee.
The technical solution used in the present invention is: a kind of welding splash-proof solution, form its weight ratio by following raw material and be: water: calcium oxide: concentration is 1% prepared Chinese ink=100.0: 20.0-30.0: 0.5-1.0.
The principle of technical solution of the present invention is: after water-soluble calcium oxide, because CaO+H
2O=Ca (OH)
2Form calcium hydroxide, adding the concentration that contains a spot of carbon again is 1% prepared Chinese ink, after mixing liquid is brushed in the workpiece welding zone, and the Ca on welding zone and workpiece surface (OH)
2Form lime carbonate after the seasoning, i.e. Ca (OH)
2=CaCO
3↓+H
2O ↑, form one deck CaCO
3Barrier film, the splash and the workpiece surface that produce when effectively preventing to weld cohere, and splash is come off automatically or one touch promptly.Simultaneously in the weld seam fusion area, when welding, CaCO
3At high temperature generate CaO and CO
2↑, CO
2At high temperature generate 2CO with C; To replacing of harmful element O in the iron rust, i.e. 3Fe
2O
3At high temperature generate 2Fe with CO
3O
4+ CO
2↑, Fe
3O
4+ CO at high temperature generates 3FeO+CO
2↑; FeO+CO at high temperature generates Fe+CO
2↑; Therefore in welding process, product surface there is certain rust-proofing effect; While CaO+SiO
2At high temperature generate CaSiO
3Therefore SiO in the butt welded seam in welding process
2Have and remove and the effect of slag former; After being applied to the lime carbonate of product surface formation, in pyritous welding process, mainly producing gas is CO
2And CO, emersion weld seam molten bath does not influence shielding gas CO fast
2Provide protection in welding process; Harmful element O in the weld seam of CO displacement simultaneously, the reduced iron element is removed the SiO in the weld seam
2, forming silico-calcium slag emersion weld seam weld pool surface, secluding air is invaded in the crystallisation process of molten bath, shields, and is not prone to the welding pore.After workpiece had welded, only retaining major ingredient at workpiece surface was CaCO
3Thing, can directly use wet rag to remove.Therefore erasability is good, the splash that forms when not only removing welding easily, and do not need other cleaning reagent to remove the vestige that sling liquid self stays.Simultaneously owing to be CaCO
3The barrier film that forms does not produce flue dust during welding, odorlessness is little to the healthy influence of operative employee.
Because the starting material that the present invention uses are calcium oxide and prepared Chinese ink, so cost is low.
Concentration among the present invention is that 1% prepared Chinese ink can substitute with fine powder graphite.Because concentration is 1% prepared Chinese ink and fine powder graphite main component is carbon.
When carbonic acid gas welds, in the welding zone, form CaCO as long as can make
3The mixed liquid of barrier film is all in protection scope of the present invention.
Embodiment
Embodiment 1: by weight, water: calcium oxide: concentration is the mixed of 1% prepared Chinese ink=100.0: 20: 0.5, place container for stirring even the above-mentioned raw material that respectively prepares, again the solution for preparing is filtered, the general filter sieve that uses is 80 to 100 orders, spraying then or being coated in needs can weld in the about 100 millimeters scope in weld.The water-soluble back of calcium oxide among the present invention forms calcium hydroxide, forms lime carbonate after the seasoning again, and the high temperature that produces during welding is easy to make the masking liquid drying, forms one deck barrier film, can prevent from effectively that high temperature from splashing to cohere at workpiece surface.And the solder ball that splashes down at workpiece surface can come off voluntarily, or one touch promptly to fall, after workpiece welding completion, when removing the anti sling liquid residue, the wet rag that uses dry wipe or wring out is wiped and is cleared away and get final product, need not to use other liquid to wipe, as: coat with lacquer with solvent or diluent etc.Use the present invention also to have antirust effect, to replacing of harmful element O in the iron rust, reduced iron element.
