Abstract
The present invention discloses two new graphite deep processing products and a preparation method thereof. The two new products comprise an aqueous conducting electric heating film coating and colloidal graphite for tungsten fine drawing and molybdenum fine drawing. According to the preparation process provided by the present invention, the traditional ball mill and the vibration mill are abandoned, a novel stirring mill (a vertical ball mill) is adopted, wherein the novel stirring mill has characteristics of high efficiency, low noise, low cost and excellent quality of the finished product; the existing scientific and technological achievements are adequately utilized for selections of the formulation and the raw materials, such that the reasonable formulation is screened, the high-end raw materials are adopted, the new product is prepared, wherein the new product has characteristics of excellent quality and cheap price, and is adapted to new market requirements.
Description
Technical field
The present invention relates to the technical field that graphite is used, refer to two kinds of graphite deep processing product innovations and preparation method thereof especially
Background technology
Graphite is a kind of nonmetal, but good thermal conductivity, electroconductibility oilness and high-temperature stability are arranged.Graphite especially its deep processing finished product has purposes widely at metallurgy, chemical industry, the many industrial sectors of electronics.
The aquadag finished product of water-based have irreplaceable effect in television indicator, computer monitor, superfine metal squeeze, the manufacturing of extraordinary electroconductive electric heating coating.
Summary of the invention
The object of the invention is intended to select only technology, and best prescription and optimum starting material produce colory waterborne conductive Electric radiant Heating Film coating and tungsten, aquadag is used in the thin wire drawing of molybdenum.
To achieve these goals; Technical solution of the present invention is: the method for manufacture of two kinds of graphite deep processing product innovations; The starting material of the electroconductive electric heating coating of water-based have deionized water, graphite, graphitized carbon black, wetting dispersing agent, water insoluble thermoplastic resin, levelling thickening material; Wherein graphite uses and is the crystalline flake graphite of median size less than 5um after the roasting, and graphitized carbon black uses the superconduction dustless carbon black, and technology is for joining slurry, grinding, filtration, adjusting and pack; The starting material of tungsten, the thin wire drawing aquadag of molybdenum have deionized water, ammoniacal liquor, CMC 99.5, wetting agent CF-01, peach gum, graphite; Graphite is selected the crystalline flake graphite of average particle size less than 5um for use; Technology gets filter cake for joining slurry, grinding, acidifying deironing press filtration; Filter cake is added water, ammoniacal liquor, CMC 99.5 making beating, and slurry is through sand milling, filtration, adjustment solid and viscosity, and packing is product.
The practical implementation method
Embodiment one
The manufacturing of the electroconductive electric heating coating of water-based
Prescription:
Component title and amount ratio %
Crystalline flake graphite (5um) 10～30
Graphitized carbon black 5～20
Wetting dispersing agent CF-01 1
Water insoluble thermoplastic resin 10～20
Levelling thickening material 0.1～3
Water supplies 100
Technology
Said components is made into slurry under high-speed stirring, slurry is put into to stir to grind grind 10h～20h in hopper, filter then in the product groove, adjust solid and viscosity as required, packing is product then.
Embodiment two
The manufacturing of tungsten, the thin wire drawing aquadag of molybdenum
Prescription:
Component title usage ratio %
Deionized water 65～75
Wetting agent CF-01 0.5～2.0
CMC 99.5 1.0～3.0
Peach gum 1.0～3.0
Crystalline flake graphite (＜5um) 20～30
Technology
In steel basin, said components is made into dispersion liquid under high-speed stirring; This dispersion liquid is put to stir in the mill and is ground 10h～20h; Put into treatment trough then with hydrochloric acid or oxalic acid acidifying deironing, reducing the difficulty of later stage acidifying deironing, the true particle diameter of the graphite in the filter cake should 90% below 500nm.
The above-mentioned solid that makes is put in the steel basin at 20%～30% graphite particulate filter cake, add the deionized water of equivalent, total amount 5/1000ths is to centesimal CMC 99.5; The ammoniacal liquor of total amount 2%; High-speed stirring makes dispersion liquid, and dispersion liquid is through sand milling 1h～2h, and 1000 eye mesh screens filter; Adjust solid and viscosity more as required, packing is finished product then.
The above; Practical ways only is that preferred implementation of the present invention is described; Be not that scope of the present invention is limited; Under the prerequisite of the spirit that does not break away from the present invention's technology, various distortion and improvement that this area engineering technical personnel make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
