Embodiment Construction

[0009] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0010] Embodiments of the invention include:

[0011] A halogen-free low-carbon environment-friendly flux, comprising the following components by weight ratio: 50%-80% polyethylene glycol, 1%-3.5% oxidized polyethylene wax, 2.5%-4.5% fatty acid ester surfactant %, high-quality rosin resin 1.3% to 3.5%, activity enhancer 0.8% to 2.6%, stabilizer 1.5% to 4.3%, and the rest is high boiling point deionized water as a solvent.

[0012] Further, the fatty acid surfactant is sodium lauryl ether sulfate, sodium cocoyl iseth...

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 [0001] The invention relates to flux, in particular to a halogen-free, low-carbon and environment-friendly flux. Background technique [0002] In the process of welding, flux is often used. The solvents of traditional fluxes are mostly alcohols, mainly methanol, ethanol and isopropanol. Due to the toxicity of methanol and its relative instability in flux, few manufacturers use it in flux formulations. Therefore, more manufacturers use ethanol or isopropanol or a mixture of the two, but they all cause certain harm to the human body. physical hazards. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a halogen-free low-carbon environment-friendly flux, which does not contain halogen, has high insulation resistance, and has good fluxing performance. carbon, reducing carbon dioxide emissions. [0004] In order to solve the above-mentioned technical problems, a technical solution adopted by the prese...
