Crystalline flake graphite is a kind of natural mineral matter, has very strong electroconductibility, thermal diffusivity and thermal insulation, and is high temperature resistant, corrosion-resistant, can be widely used in industries such as refractory materials, steel industry, electric power, household electrical appliance, sealing.Because crystalline flake graphite is a kind of flour, and very strong oilness is arranged each other, be difficult to it is combined.
Crystalline flake graphite will be combined, make it have very strong tensile strength, toughness and flexibility, the product of producing can guarantee the original characteristic of crystalline flake graphite, needs the manufacture method that a kind of product of scale graphite is provided badly.
A kind of manufacture method of product of scale graphite comprises the steps:
A) mix stirring: with weight percentage is 60～85% crystalline flake graphite, 15～40% chlorinatedpolyethylene, calcium stearate 3～5%, thiol methyl tin 1～3%, and o-phthalic acid dibutyl ester 2～3% joins to mix in the steel basin and stirs; The described thermo-stabilizer of thermo-stabilizer softening agent is that described component summation is no more than 100%.
B) stirring of heating: after stirring, heat to 60～80 ℃ of restir;
C) refining: the material that stirs continues 80～100 ℃ of refinings that heat up, and makes platy shaped particle;
D) compacting: platy shaped particle is passed through vibratory screening apparatus equably with size distribution, 3～5 pairs of pressure rollers compactings in compounding machine, roller temperature is at 75～85 ℃.
At above-mentioned steps d) in, the gap between the described pressure roller is 0.1～10mm, according to varying in size of the gap of regulating, produces crystalline flake graphite coiled material or sheet material.
In above-mentioned steps, when producing the crystalline flake graphite wire rod, be that the platy shaped particle that will refine out in the described step c) drops in the forcing machine, extrude wire rod.
Compared with prior art, advantage of the present invention and positively effect are:
The present invention mixes by crystalline flake graphite and the chlorinatedpolyethylene with different size, through heating, stir, refine, technology such as compacting makes crystalline flake graphite coiled material, sheet material and wire rod.The present invention makes full use of the characteristic of crystalline flake graphite, utilize the interpolation material that crystalline flake graphite is coated, through above-mentioned kinds of processes,, it is combined according to the production principle of expanded graphite paper, rubber, plastics, can either guarantee the original characteristic of crystalline flake graphite, because performance performance between rubber and plastics of chlorinatedpolyethylene, toughness is very strong, has flexibility simultaneously again, the density height, thereby make product have very strong tensile strength, toughness and flexibility again.Can effectively substitute the application of various non-ferrous metals and expanded graphite produsts etc. by the present invention, have very high value.
