Abstract

The present invention is applicable to the technical field of welding and cutting gas, and provides a metal welding and cutting gas and a preparation method thereof. The metal welding and cutting gas includes gas, additives and auxiliary agents, and the weight ratio of the gas, additives and auxiliary agents is 1000:(8 ‑20): (5‑7); the additive includes the following raw materials: 2-methylphenol, m-hydroxybenzamide, ferrocene, nano-carbon, sulfurized fatty acid ester, fusel oil; the auxiliary agent includes the following Raw materials in parts by weight: modified strontium nitrate, ethanol, acetone, toluene, methyl tert-butyl ether, cyclohexane; the metal welding and cutting gas provided by the embodiment of the present invention, through the addition of additives and auxiliary agents, can play a role in the gas system To achieve synergistic effects, the product has low energy consumption, no environmental pollution, good cutting quality, smooth weld surface, little welding slag, faster cutting speed than acetylene, safe to use, no tempering, no detonation, safe storage, The chemical performance is stable, long-term storage will not deteriorate, the container is light, and it is easy to carry.

Description

technical field [0001] The invention belongs to the technical field of welding and cutting gas, and in particular relates to a metal welding and cutting gas and a preparation method thereof. Background technique [0002] Acetylene has been used as a welding and cutting gas for a hundred years, but it is easy to form carbon deposits after welding and cutting, which is not smooth and easy to solidify near the cutting edge, so it needs to be ground again to remove carbon deposits, resulting in secondary costs. Moreover, acetylene is explosive, has a low safety factor, and the production process not only consumes energy and pollutes the environment, but there are many defects and hidden dangers in the production, storage, transportation, use, environmental protection and price of acetylene. [0003] With the development of productivity and the progress of society, human beings pay more and more attention to environmental protection, energy saving, safety and efficiency, and try ...
