Abstract

The invention discloses a high heat stability welding splashing preventing agent and belongs to the field of metal welding splashing preventing chemical additives. Organic selenium compounds are addedin the high heat stability welding splashing preventing agent, a metal selenide film is generated, and adhesion between splashing metal particles and weldment can be avoided while stability of oily substances is improved; and acid leaching is performed on vermiculite to remove acid-soluble components in the vermiculite and break through pores, citrate can be adsorbed, isocyanate is mixed in, pressurizing mixing treatment is performed, pores are broken through, the adsorbing effect is improved, the vermiculite expands due to heat, and the adsorbed metal particles can be treated in a concentrated manner conveniently; and acrylic acid, acrylamide and the like are used for making polymer gel to serve as a colloidal condition stable component of active ingredients of the high heat stability welding splashing preventing agent, and the splashing preventing effect can be effectively stabilized. The high heat stability welding splashing preventing agent solves the problem that a welding splashing preventing agent commonly used at present is not good in stability and splashing preventing effect under high temperature.

Description

technical field [0001] The invention belongs to the technical field of anti-splash chemical additives for metal welding, and in particular relates to an anti-splash agent for high thermal stability welding. Background technique [0002] The metal welding process is a very widely used metal processing process in modern industry, including marine ships, aerospace, railway transportation, petrochemical industry, hardware construction and other industries. When welding, it is necessary to connect the welding material and the metal base material into a whole under high temperature and high pressure conditions. During the welding process, due to the addition of external gas in the mixture, the high current generates arc light and high temperature, and when the temperature rises sharply, a lot of spatter will be generated. These spatters are easy to fall on the metal surface near the weld and cool down. After that, it sticks to the surface of the metal base metal, which is the so-...
