Abstract
The invention discloses a corrosion resisting anti-passivation conducting material, belonging to the technical field of conducting material. The conducting material comprises graphite and gelatinizing agent, and filler can be added in the graphite or the gelatinizing agent, wherein the formula comprises the following ingredients by weight percent: 20-60% of gelatinizing agent, 25-80% of graphite and 0-55% of filler. After the material is moulded, the cellular structure formed on the surface of the moulded material enlarges the surface contact area to prolong or avoid generation of surface independent phase membrane or adsorbability membrane; in addition, the surface of the moulded material has self-falling-off function, so if the independent phase membrane or adsorbability membrane is generated, the membrane can still be washed off by water to expose fresh surface of the material, thereby ensuring recycling of the material and realizing anti-passivation effect.
Description
Technical field
The invention belongs to the electro-conductive material technical field, be specifically related to a kind of corrosion resisting anti-passivation conducting material.
Background technology
As everyone knows, electro-conductive material is except being used for the conduction current, and some electro-conductive material is made into sensing member because of the variation of its resistivity with temperature, humidity, factor such as stressed changes.Yet, when monitoring high temperature, high heat, strongly-acid, strong basicity or complicated heterogeneous system environment, the probe of sensing device, probe or transmitter and in succession the conductor of these elements will produce problems such as chemical corrosion, galvanic corrosion, passivation.Disclose among the Chinese patent publication number CN 101460649A a kind of " conductive corrosion-resistant material and manufacture method thereof "; in this patent; introduced a kind of by titanium; the a series of engineering of conductive corrosion-resistant material process that boron and nitrogen etc. are elementary composition; this material is covered substrate surface; form layer protecting film; the surface of its manufacture process requirement substrate must be precious metal titanium or titanium alloy; under high temperature oxygen barrier environment; the surface that boron nitride powder is adhered to substrate; carry out nitriding then and handle under 700 to 1100 ℃ high temperature, the product after making can be used for the metal bipolar plate of fuel cell.Though this product has solved etching problem to a certain extent, mainly have following shortcoming: 1) problem of passivation fails to solve; 2) this product is with metal titanium corrosion resistant critical material, and forms with the technology manufacturing of complexity, and production cost is inevitable high; 3) nitriding processing meeting brings certain pollution to environment.
Summary of the invention
The present invention aims to provide a kind of corrosion resisting anti-passivation conducting material, and this electro-conductive material has corrosion-resistant and anti-inactivating performance, and employed starting material are common, manufacturing process is simple to operate, low cost of manufacture, manufacturing processed can not brought environmental pollution.
The objective of the invention is to be achieved by the following technical programs:
A kind of corrosion resisting anti-passivation conducting material is characterized in that mainly comprising graphite, jelling agent, and the formula for raw stock of this material is to carry out proportioning by following weight percent:
Jelling agent: 20%～75%
Graphite: 25%～80%.
Also can add stopping composition in described graphite or the jelling agent, weight percent is 0%～55%.
Described jelling agent is gypsum, lime, cement, water glass, pitch and their mixture.
Described stopping composition is carbon fiber powder, clay, sand, slag, flyash, slag, slag, Sodium Silicofluoride, aluminum phosphate, metal powder or non-metal solid and their mixture.
The useful effect of corrosion resisting anti-passivation conducting material of the present invention is that this material has excellent corrosion resisting performance; Behind the forming materials, the multi-cellular structure that the surface forms will increase surperficial contact area, can delay or the generation of stop surface independence phase film or adsorptivity film, and have the autospasy drop, even independent phase film or adsorptivity film generate, wash once water, just can rinse out film, make material expose unsalted surface, to guarantee material usefulness more capable of circulation, to reach anti-passivation effect.In the goods of this material, also can add industrial residues such as flyash, slag, slag, slag, except improving gelling bonding strength, water resistance, also also play to a certain extent turn waste into wealth, the effect of resource reutilization.
