Abstract

The invention discloses water-based environmental-friendly welded anti-flash liquid and belongs to the technical field of metal welding. The water-based environmental-friendly welded anti-flash liquid is characterized by comprising the following components in percentage by weight: 10.0-30.0% of a high-polymer film-forming agent, 3.0-6.5% of a flame retardant, 1.0-2.5% of a sustained-release formulation, 1.0-2.0% of a pH buffer agent, 10.0-20.0% of ethanol and the balance of water, wherein the high-polymer film-forming agent comprises hydroxypropyl methyl cellulose, polyvinyl alcohol and polyethylene glycol according to a weight ratio of 3:5:2; the flame retardant is sodium hydrogen phosphate; the corrosion inhibitors refer to sodium benzoate, sodium silicate and calcium sulfate according to a weight ratio of 5:4:1; and the pH buffer agent is borax. The water-based environmental-friendly welded anti-flash liquid disclosed by the invention has the beneficial effects that the anti-flash liquid has excellent thermal stability, water solubility, corrosion inhibition property and simplicity in cleaning; and the formulas belong to bio-based green resources and have excellent environment friendliness.

Description

Technical field [0001] The invention belongs to the technical field of metal welding anti-splash additives, and more specifically relates to a water-based environment-friendly welding anti-splash liquid and a preparation method thereof. Background technique [0002] Welding process is an indispensable universal processing technology in all walks of life. As long as there is a need for metal connection, most of the welding process needs to be completed. Welding is to heat two base materials that need to be connected together through a welding rod and heat them locally at a high temperature, so that the two base materials are firmly connected by solder. It is a very common phenomenon that "welding" appears during high-temperature heating. The "welding" splashes around and falls on the base material. Because the temperature of the "welding" is extremely high, it will be The materials are firmly connected together, and after cooling, a solder ball is formed. There are sometimes man...
