The graphite line comprises 73% to 77 % of graphite, 13 % to 17 % of glass fiber and 8% to 12% of pressure sensitive rubber and volatile substance. Content of carbon in the graphite is no less than 99 percent. The graphite line has the advantages of being superconducting, long in service life, raw-material-saving, and low in manufacture cost.
Description
Technical field
The present invention relates to lightning protection device technique field, relate in particular to a kind of graphite line that is used to make the lightning protection element.
Background technology
The graphite line that adopts in the lightning protection body utilizes the traditional approach preparation, the graphite line that the content component that it comprised makes; The resistance of general lead is big, and the flow of current direction is not unique, makes the poor electric conductivity of graphite line; The soil function that adapts to various environmental conditions is poor, and useful life is short, needs constantly to change graphite line in a short time; Cost is high, wastes time and energy.
Summary of the invention
The purpose of the embodiment of the invention is to provide a kind of graphite line, is intended to solve the graphite line that adopts conventional graphite components contents that line comprises to make, poor electric conductivity, the technical problem that useful life is short.
The embodiment of the invention is to realize like this; A kind of graphite line comprises that weight percent content is 73% ~ 77% graphite, and weight percent content is 13% ~ 16% glass fiber; Weight percent content be 8% ~ 11% detest quick glue and volatile matter, carbon content is not less than 99% in the said graphite.
As improving further, said graphite line also comprises the corrosion-resistant enhancing silk that is used to increase said graphite line tensile strength.
As improving further; The weight percent content of said graphite is 75%; The weight percent content of said glass fiber is 14%, and the said weight percent content of detesting quick glue and volatile matter is 9%, and the said corrosion-resistant weight percent content that strengthens silk is 2%.
As improving further, the diameter of said glass fiber is 0.1mm, and said glass fiber adopts 12 ~ 13 and be arranged side by side.
As improving further, said corrosion-resistant enhancing silk is stainless steel wire, copper wire, steel wire or nickel wire.
After having adopted technique scheme, beneficial effect of the present invention: because various components contents have reached optimal mix proportion row through experiment in the graphite line, the graphite worm that glass fiber obtains after with glue and graphite expansion is combined with each other; Integrate the conducting direction of graphite worm through glass fiber, made graphite worm directed conduct electricity, and the graphite line that makes employing multiply mode when using; Sectional area of wire is big, has reduced resistance, has solved the graphite line of traditional approach preparation; Poor electric conductivity; The shortcoming that can not adapt to various condition soil, the problem that useful life is short, thus reached the graphite line superconduction; Imbed underground permanent use, obviously improve useful life.
Owing in the formulated component of graphite line, added stainless steel wire or copper wire or nickel wire, so just can increase the tensile strength of graphite line greatly, improved graphite line security reliability in use.
