Abstract
The invention provides an antioxidant for an ultrafine electrician braided copper wire. The antioxidant comprises the following chemical components in percentage by weight: 15%-30% of a scale and corrosion inhibitor, 15%-30% of ethanol, 12%-20% of benzotriazole, 20%-25% of rare-earth salt, 1%-5% of sodium molybdate, 2%-6% of zinc salt, 0.5%-3% of citric acid, 4%-8% of propylene glycol methyl ether acetate and the balance of water; the antioxidant is nontoxic and environmentally friendly; after a copper wire is annealed and cooled, a layer of uniform, compact and difficult-to-fall protective film can be generated on the surface of the copper wire, so that the copper wire has good anti-tarishing capacity and antioxidant capacity; the storage life and service life of the copper wire are effectively prolonged; and the production cost is reduced.
Description
Technical field
The invention belongs to electric installation, field protected by electronic component connection line, particularly, relate to a kind of ultra-fine electrician's copper litz wire antioxidant.
Background technology
In the industry of copper wire processing now, the share of the market share of copper material processing is increasing, and particularly in plating, spraying, cable, wiring board, CNC, mould, punching press five metals, the industries such as powder metallurgy, the proportion occupied is year by year in the trend risen.
Going from strength to strength of industry, the quality requirements of product is also constantly improved, but in the process of Copper fabrication, copper and copper alloy are after processing cleaning, occur that the problem be oxidized is a disadvantage in the industry always, especially for copper wire, copper litz wire and electrician's copper soft whipping wire that electric installation, electronic component connect, after making copper wire, surface is very easily oxidized, occur that the situation of oxidation is very general, often within after cleaning, drying several hours, occur oxidation stain, can verdigris be generated under normal temperature oxidation, both ventilation breather is green; Maybe may be oxidized to Red copper oxide, for brick-red, after a few days, play oxidation sludge.The copper wire that copper material is originally more valuable, adds now expensive tooling cost and labour cost, and the product allowing many producers look at a pile oxidation is worried, and the product how processing oxidation has been delivered goods into the anxious problem that must solve of many producers.
Summary of the invention
For solving above-mentioned Problems existing; the object of the present invention is to provide a kind of ultra-fine electrician's copper litz wire antioxidant; nontoxic, environmental protection; after copper wire annealing cooling; can produce on copper wire surface one deck evenly, fine and close and be difficult to the protective membrane that comes off; make copper wire have good Anti-tarnishing ability, resistance of oxidation, effectively promote storage life and the work-ing life of copper wire, reduce production cost.
For achieving the above object, technical scheme of the present invention is:
A kind of ultra-fine electrician's copper litz wire antioxidant, described antioxidant comprises the chemical composition of following weight percent: anti-incrustation corrosion inhibitor: 15 ~ 30%, ethanol: 15 ~ 30%, benzotriazole: 12 ~ 20%, rare-earth salts: 20 ~ 25%, Sodium orthomolybdate: 1 ~ 5%, zinc salt: 2 ~ 6%, citric acid: 0.5 ~ 3%, 1-Methoxy-2-propyl acetate: 4 ~ 8%, all the other are water.
Preferably, described antioxidant comprises the chemical composition of following weight percent: anti-incrustation corrosion inhibitor: 15 ~ 20%, ethanol: 15 ~ 20%, benzotriazole: 14 ~ 16%, rare-earth salts: 20 ~ 24%, Sodium orthomolybdate: 2 ~ 3%, zinc salt: 4 ~ 5%, citric acid: 1 ~ 2%, 1-Methoxy-2-propyl acetate: 5 ~ 7%, all the other are water.
