Description
Technical field
The invention belongs to electrical equipment, electronic component connection line to protect field, and in particular, to a kind of proof copper-wire braided line
Use protective agent.
Background technology
In the industry of copper wire processing now, the share that the market of copper material processing is occupied is increasing, particularly in electricity
The industries such as plating, spraying, cable, wiring board, CNC, mould, punching press hardware, powder metallurgy, the proportion occupied become in what is risen year by year
Gesture.
Industry goes from strength to strength, and the quality requirements of product are also constantly improved, but during Copper fabrication, copper and
Copper alloy after processing is cleaned, the problem of aoxidizing an always disadvantage in the industry, particularly for electrical equipment, electricity
Copper wire, copper litz wire and the electrician's copper soft whipping wire of subcomponent connection, after copper wire is made, surface easily aoxidizes, and aoxidizes
Situation it is extremely widespread, often there is oxidation stain in a few houres after cleaning, drying, verdigris can be generated under normal temperature oxidation, both alkali formula
Copper carbonate, for green；Or cuprous oxide may be oxidized to, it is brick-red, oxidizing slag is played after a few days.Copper material is originally somewhat expensive
The copper wire of weight, plus present expensive processing cost and labour cost, allows the producer of many to look at the product that a pile aoxidizes and worries,
How handling the product delivery of oxidation must solve the problems, such as into many producers are anxious.
The content of the invention
It is above-mentioned to solve the problems, such as, it is an object of the invention to provide a kind of proof copper-wire braided line protective agent, nontoxic,
Environmental protection, after copper wire annealing cooling, one layer of uniform, densification can be produced on copper wire surface and is difficult to the protective film to come off so that copper
Silk have good Anti- tarnishing ability, oxidation resistance, effectively lifted proof copper-wire braided after proof copper-wire braided line pot-life and
Service life, reduces production cost.
To reach above-mentioned purpose, the technical scheme is that：
A kind of proof copper-wire braided line protective agent, the protective agent include the chemical composition of following percentage by weight：Polypropylene
Acid esters lotion：15 ~ 20%, ethanol：15 ~ 30%, benzotriazole：12 ~ 20%, rare-earth salts：15 ~ 25%, sodium molybdate：1 ~ 5%, zinc salt：
2 ~ 6%, fatty glyceride：0.5 ~ 3%, propylene glycol methyl ether acetate：4 ~ 8%, remaining is water.
Preferably, the protective agent includes the chemical composition of following percentage by weight：Polyacrylate dispersion：16 ~ 18%,
Ethanol：15 ~ 20%, benzotriazole：15 ~ 18%, rare-earth salts：15 ~ 20%, sodium molybdate：3 ~ 4%, zinc salt：4 ~ 6%, fatty acid glycerine
Ester：1 ~ 2%, propylene glycol methyl ether acetate：5 ~ 7%, remaining is water.
Further, the protective agent includes the chemical composition of following percentage by weight：Polyacrylate dispersion：17%, second
Alcohol：15%, benzotriazole：15%, rare-earth salts：16%, sodium molybdate：3%, zinc salt：5%, fatty glyceride：2%, propylene glycol monomethyl ether
Acetate：6%, remaining is water.
In addition, the rare-earth salts is selected from Nd (NO3)3、LaCl3、La(NO3)3、CeCl3、Ce(NO3)3、PrCl3In one kind or
More than one.
Separately have, the zinc salt is ZnSO4Or ZnCl2。
Again, the copper litz wire is formed by the stranded copper wire braiding of a diameter of 0.03 ~ 0.05mm.
The beneficial effects of the present invention are：
Copper wire and the protective agent generate insoluble and fine and close sull, thus prevent copper wire anodic solution or
Promote the passivation of copper wire, so as to suppress the corrosion of copper wire.Copper wire can generate the salt of indissoluble with protective agent, so that copper wire and corruption
Medium isolation is lost, from corrosion.Benzotriazole can generate chelate Cu (C with copper wire6H4N3)2, protection proof copper-wire braided formation
The surface of copper litz wire is not oxidized.
