Problems solved by technology

[0002] Chemical industry, the full name of chemical industry, is very closely related to human production and life. In modern life, chemical products are inseparable almost anytime and anywhere. Chemical products permeate in various industries and fields such as home furnishing, agriculture, and industry. Among them, flux is widely used. In industrial welding, the existing fluxes mostly use halogen-containing surfactants. Although the fluxing effect is good and the cost is low, it is easy to leave residues on the metal surface after long-term use, the process is complicated, the environment is polluted, and the atmosphere is damaged. And other issues

Abstract

The invention discloses a novel cleaning-free flux. The flux comprises the following components in percentage by mass: 80% of solvent, 10% to 30% of activating agent, 5% to 20% of filming agent, and 5% to 10% of anti-oxidizing thermal stabilizing agent, wherein the activating agent comprises the following components in percentage by mass: 50% of adipic acid, 30% of sebacic acid, and 20% of benzotriazole. By adopting the method, the cleaning-free flux has the advantages that the smoke is little, the pungent odor is little, the tin applying speed is high, the metal welding surface is clean, the wettability is better, the safety and environment-friendly effects are realized, the toxicity and harm are avoided, the safety in use is realized, and the like; the broad market prospect is obtained in the popularizing of the novel cleaning-free flux.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a novel no-clean flux. Background technique [0002] Chemical industry, the full name of chemical industry, is very closely related to human production and life. In modern life, chemical products are inseparable almost anytime and anywhere. Chemical products permeate in various industries and fields such as home furnishing, agriculture, and industry. Among them, flux is widely used. In industrial welding, the existing fluxes mostly use halogen-containing surfactants. Although the fluxing effect is good and the cost is low, it is easy to leave residues on the metal surface after long-term use, the process is complicated, the environment is polluted, and the atmosphere is damaged. And other issues. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a new type of no-clean flux, which is added into the flux by using a new ...
