Problems solved by technology

Some existing anti-splash agents also have potential safety hazards. For example, CN104722957A discloses an environmentally friendly spray-type welding anti-splash agent and its preparation method. As a solvent, oil has a low flash point, is flammable, and has a fire hazard, and the solvent is highly volatile and harmful to human health.
[0004] In summary, the existing protective agents for metal welding base metal generally have the following defects: (1) potential safety hazards, flammability, high toxicity; (2) difficult to clean, poor rust resistance; (3) low viscosity, poor dispersion and only suitable for Good for flat welding, horizontal welding, overhead welding and vertical welding, etc.

Abstract

The invention discloses a water-based environment-friendly metal welding base metal protective agent. The water-based environment-friendly metal welding base metal protective agent is prepared from, by weight percent, 9%-15% of a polymer film-forming agent, 8%-16% of a spreading agent, 5%-10% of a wetting flatting agent, 0.5%-5% of a rust-inhibiting additive, 12%-18% of a cosolvent and 45%-65% of deionized water. The raw materials adopted in the protective agent are environment-friendly, non-poisonous and degradable components; the prepared metal welding base metal protective agent can effectively avoid welding splash adhesion, is easy to clean and moderate in viscosity, and has excellent antirust performance; and the protective agent is suitable for multiple welding positions of flat welding, transverse welding, vertical welding, overhead welding and the like. The invention further discloses a preparation method of the water-based environment-friendly metal welding base metal protective agent. According to the preparation method, no heating is needed, operation is easy, the application range is wide, and cost is low.

Description

technical field [0001] The invention belongs to welding chemical technology, in particular to a water-based environment-friendly protective agent for metal welding base material and a preparation method thereof. Background technique [0002] Metal welding is a very important technology in modern industry. It is indispensable in many manufacturing situations. However, during welding, the partially melted electrodes and base metals often scatter around due to the violent expansion of the gas, forming spatter. Commonly known as welding flowers. These metal spatters emit light due to high temperature. Once they touch the base metal, the base metal will also melt rapidly at the contact point, making the spatter mix with the base metal, and firmly adhere to the surface of the base metal after cooling, affecting the surface flatness of the workpiece. , Grinding with grinding wheels is not only time-consuming and laborious, but also grinds the base metal; welding spatter is mainly ...
