Abstract
This invention discloses an organic composite additive for manufacturing ultra-thin double-side-smooth electrodeposited copper foil. The organic composite additive is composed of (per unit): poly(ethylene glycol) 5-20 g/L, sodium polydithio-dipropyl sulfonate 500-1000 mg/L, thiourea 100-500 mg/L, and sodium 3-[[(dimethylamino)thioxomethyl]thio]propanesulfonate 30-70 mg/L. The electrodeposited copper foil manufactured by using the organic composite additive has surface roughness less than 0.25 mums. The individual grain of the electrodeposited copper foil is lamellar crystal, and the surface is mirror-like. The electrodeposited copper foil has high tensile strength and high elongation percentage, and can be used as a substitute for calendered copper foil for application in soft printed circuit board and polymeric Li-ion battery. The method for manufacturing the electrodeposited copper foil is simple and low cost compared with that for manufacturing calendered copper foil. Besides, the costs for manufacturing soft printed circuit board and polymeric Li-ion battery can be largely reduced.
Description
Technical field
The present invention relates to the additive of electrolytic copper foil production usefulness, particularly a kind ofly produce the additive that the ultrathin double-face optical electrolytic copper foil is used.
Background technology
At present, the Copper Foil product is divided into two kinds, rolled copper foil and electrolytic copper foil.The two-sided light face that is of rolled copper foil is mainly used in the electro-conductive material and the polymer Li-ion battery of printed wiring soft board.But all be higher than electrolytic copper foil owing to produce the investment and the production cost of rolled copper foil, and, make that rolled copper foil unit price in the market is more than three, four times of electrolytic copper foil at least because the limitation of the production unit of rolled copper foil directly influences its product length and wide cut.Therefore make that also the production cost of printed wiring soft board and polymer Li-ion battery is very high.Existing electrolytic copper foil is that one side is the light face, and one side is a hair side.The crystallization of the single nucleus crystal grain of Copper Foil is a pyramid-shaped, and more than RZ 〉=3 of Copper Foil product hair side micron, the hair side surfaceness is bigger, therefore is mainly used in the electro-conductive material of printed wiring hardboard.In order to improve the technical indicator of electrolytic copper foil hair side, make it can substitute rolled copper foil, people have done many effort, but up to the present, also do not obtain the ideal effect.
Summary of the invention
The objective of the invention is to, a kind of organic blending additive that the ultrathin double-face optical electrolytic copper foil is used of producing is provided.Solve the bigger technical problem of hair side surfaceness of existing electrolytic copper foil.The electrolytic copper foil that utilizes the present invention to produce, hair side surfaceness be less than 0.25 micron, and have better tensile strength and unit elongation, can replace rolled copper foil to be used for the production of printed wiring soft board and polymer Li-ion battery.Use the succinctly practicality of method that the present invention produces electrolytic copper foil, production cost is significantly less than the production cost of rolled copper foil, can reduce the production cost of printed wiring soft board and polymer Li-ion battery greatly.
Technical scheme of the present invention.Produce the organic blending additive that the ultrathin double-face optical electrolytic copper foil is used, it is characterized in that: the organic blending additive of each unit is to make with following proportion raw material; Polyoxyethylene glycol 5-20 grams per liter, sodium polydithio-dipropyl sulfonate 500-1000 mg/litre, thiocarbamide 100-500 mg/litre, methyl thiocarbamoyl propane sulfonic acid sodium 30-70 mg/litre.
The organic blending additive that above-mentioned production ultrathin double-face optical electrolytic copper foil is used, the organic blending additive of each unit is to make with following proportion raw material better; Polyoxyethylene glycol 5-15 grams per liter, sodium polydithio-dipropyl sulfonate 600-900 mg/litre, thiocarbamide 100-400 mg/litre, methyl thiocarbamoyl propane sulfonic acid sodium 30-70 mg/litre.
The organic blending additive that aforesaid production ultrathin double-face optical electrolytic copper foil is used, the organic blending additive of each unit is to make with following proportion raw material better; Polyoxyethylene glycol 5-15 grams per liter, sodium polydithio-dipropyl sulfonate 700-800 mg/litre, thiocarbamide 100-300 mg/litre, methyl thiocarbamoyl propane sulfonic acid sodium 40-60 mg/litre.
Compared with the prior art, the present invention is a kind of organic blending additive that adopts new raw material and proportioning to make.This Application of Additives has solved the bigger technical problem of hair side surfaceness of existing electrolytic copper foil, has obtained extraordinary technique effect.Utilize the electrolytic copper foil of this Additive Production, the hair side surfaceness is less than 0.25 micron, single crystallization crystal grain is laminated crystalline, be that the layer growth thing has the step edge that is parallel to a certain crystallographic axis of matrix, layer itself comprises countless microcosmic steps, and all steps on the crystal face are expanded along same direction.Its hair side is " minute surface " shape (promptly as minute surface) fully.And have better tensile strength and unit elongation, can replace rolled copper foil to be used for the production of printed wiring soft board and polymer Li-ion battery fully.The method of using this Additive Production electrolytic copper foil is succinctly practical, and production cost is significantly less than the production cost of rolled copper foil, can reduce the production cost of printed wiring soft board and polymer Li-ion battery greatly.
Embodiment
Embodiment 1
The organic blending additive of each unit is made with following proportion raw material; Polyoxyethylene glycol 10 grams per liters, sodium polydithio-dipropyl sulfonate 750 mg/litre, thiocarbamide 200 mg/litre, methyl thiocarbamoyl propane sulfonic acid sodium 50 mg/litre.
The using method of this organic blending additive is exemplified below:
Getting copper content is that 85g/l, acid content are the electrolytic solution adding electrolyzer of 105g/l, every electrolyzer per hour flow of electrolytic solution is the 30-60 cubic meter, used electrolytic solution is identical with the consumption that the conventional electrolysis Copper Foil is produced, before electrolysis, in electrolytic solution, add organic blending additive by the 400ml/ platform, under 50-55 ℃ condition, carry out electrolysis, in the electrolytic process by adding organic blending additive in the 150-250ml/ branch clockwise electrolytic solution.The hair side of the electrolytic copper foil that this example is prepared is mirror-like, and the crystallization of crystal grain is a laminate structure, and the thickness of Copper Foil is no more than 8 μ m.Through test, the hair side surfaceness is no more than 0.25 μ m, tensile strength 45.3kg/ square millimeter, unit elongation 5.5%.
