Abstract
The invention discloses a halogen-free low-carbon environment-friendly flux. The flux comprises the following components in percentage by mass: 50% to 80% of polyethylene glycol, 1% to 3.5% of oxidized polyethlene wax, 2.5% to 4.5% of fatty acid ester surface active agent, 1.3% to 3.5% of high-quality abieten, 0.8% to 2.6% of active reinforcing agent, 1.5% to 4.3% of stabilizing agent, and the balance of high-boiling point deionized water as a solvent. By adopting the method, the halogen-free low-carbon environment-friendly flux has the advantages that the halogen is not contained, the insulation resistance is high, and the welding assisting performance is good; compared with the traditional alcohol-based flux, the flux uses water as the solvent, the carbon content is lower, and the emission of carbon dioxide is reduced.
Description
Technical field
The present invention relates to scaling powder, particularly relate to a kind of Halogen low-carbon environment-friendly scaling powder.
Background technology
Welding in use, is usually used scaling powder, and the solvent of traditional scaling powder is main body mainly with alcohols material, mainly contains three kinds of methyl alcohol, ethanol and isopropyl alcohols.Due to the toxic of methyl alcohol and the relative instability in scaling powder thereof, seldom there is producer to use in formulations of solder flux, therefore use ethanol or isopropyl alcohol or both to mix the producer of use more, but all human body is caused to certain health harm.
Summary of the invention
The technical problem that the present invention mainly solves is not to provide a kind of Halogen low-carbon environment-friendly scaling powder, halogen-containing, insulaion resistance is high, help weldering property good, and this scaling powder, take water as primary solvent than traditional more low-carbon (LC) of alcohol based scaling powder, reduces CO2 emission simultaneously.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of Halogen low-carbon environment-friendly scaling powder is provided, the component composition that comprises following weight proportion: polyethylene glycol 50%～80%, OPE 1%～3.5%, fatty acid ester surfactant 2.5%～4.5%, high-quality rosin fat 1.3%～3.5%, active reinforcing agent 0.8%～2.6%, stabilizing agent 1.5%～4.3%, all the other are that higher boiling deionized water is as solvent.
In a preferred embodiment of the present invention, described fatty acid surfactant is one or both mixture wherein in dodecyl alcohol ether sodium sulfate, cocoyl sodium isethionate, palm stearin alcohol phosphate.
In a preferred embodiment of the present invention, described stabilizing agent is the mixture of dibasic lead stearate and lead sulfate tribasic in lead salt stabilizer.
In a preferred embodiment of the present invention, the percentage by weight of described each composition is: polyethylene glycol 75%, OPE 2%, fatty acid ester surfactant 4%, high-quality rosin fat 2.4%, active reinforcing agent 2.6%, stabilizing agent 3.5%.
The invention has the beneficial effects as follows: the invention provides a kind of Halogen low-carbon environment-friendly scaling powder, halogen-containing, insulaion resistance is high, help weldering property good, this scaling powder, take water as primary solvent than traditional more low-carbon (LC) of alcohol based scaling powder, does not reduce CO2 emission simultaneously.
The specific embodiment
To the technical scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:

Further, described fatty acid surfactant is one or both mixture wherein in dodecyl alcohol ether sodium sulfate, cocoyl sodium isethionate, palm stearin alcohol phosphate.
Further, described stabilizing agent is the mixture of dibasic lead stearate and lead sulfate tribasic in lead salt stabilizer.
Further, the percentage by weight of described each composition is: polyethylene glycol 75%, OPE 2%, fatty acid ester surfactant 4%, high-quality rosin fat 2.4%, active reinforcing agent 2.6%, stabilizing agent 3.5%.
The invention has the beneficial effects as follows: the invention provides a kind of Halogen low-carbon environment-friendly scaling powder, halogen-containing, insulaion resistance is high, help weldering property good, this scaling powder, take water as primary solvent than traditional more low-carbon (LC) of alcohol based scaling powder, does not reduce CO2 emission simultaneously.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
