Abstract
A kind of graphite-pipe, the raw material for making the graphite-pipe is the composition of following parts by weight：58 parts of 65 70 parts of graphite powder, 20 25 parts of phenolic resin and graphene.The advantage of the invention is that：The graphite-pipe of the present invention, with the addition of graphene, and then the graphite-pipe for making to be prepared into both has corrosion-resistant, excellent tension and compressive mechanical property, substantially increases the electrical and thermal conductivity performance of graphite-pipe again in manufacturing process.
Description
Technical field
The invention belongs to graphite equipment technical field, more particularly to a kind of graphite-pipe.
Background technology
The graphite-pipe now used is formed by high viscosity phenolic resin and graphite powder by hot extrusion, is made for the installation of graphite industry
With.Wherein, graphite-pipe material composition is：Phenolic resin mass percent is about 23%, and graphite powder mass percent is about
77%, mechanical property is smaller after completing, with internal diameter 22mm, exemplified by external diameter 32mm：Tensile strength 20MPa, bending strength
250MPa；Therefore, a kind of mechanical property that both can guarantee that graphite-pipe is researched and developed, and can, which improves conductive and heat conductivility graphite-pipe, is
It is highly desirable.
The content of the invention
The technical solution adopted for the present invention to solve the technical problems is：A kind of graphite-pipe, it is characterized in that, it is by following heavy
Measure the composition of part：Graphite powder 65-70 parts, phenolic resin 20-25 parts and graphene 5-8 parts；And the preparation method of the graphite-pipe
It is as follows：
(1) graphite powder, phenolic resin and graphene are taken according to formula rate, then by graphite powder, phenolic resin and graphite
Alkene is mixed and crushed, and the material of crushing is poured into mechanical hopper, then uniformly continual equal carrying out mixing in material input auger machine
It is even, and the electric current of control machinery hopper is between 10~20 amperes；
(2) well mixed material is sent into extrusion forming in extrusion molding dies, obtains tubing semi-finished product；Extrusion forming mold
Tool includes the die head and pipe outlet section set gradually, and at 90~100 DEG C, the temperature control of pipe outlet exists the temperature control of die head
180~200 DEG C；
(3) tubing semi-finished product are checked, defective to be rejected, flawless, length is sawed on demand, into finished product graphite
Pipe..
The beneficial effects of the invention are as follows：The graphite-pipe of the present invention, both with corrosion-resistant, tension and compressive mechanical property, again
Substantially increase the electrical and thermal conductivity performance of graphite-pipe.
Embodiment
Specific embodiment：A kind of graphite-pipe, it is characterized in that, it is made up of following parts by weight：Graphite powder 65-70 parts, phenol
Urea formaldehyde 20-25 parts and graphene 5-8 parts；And the preparation method of the graphite-pipe is as follows：
(1) graphite powder, phenolic resin and graphene are taken according to formula rate, then by graphite powder, phenolic resin and graphite
Alkene is mixed and crushed, and the material of crushing is poured into mechanical hopper, then uniformly continual equal carrying out mixing in material input auger machine
It is even, and the electric current of control machinery hopper is between 10~20 amperes；
(2) well mixed material is sent into extrusion forming in extrusion molding dies, obtains tubing semi-finished product；Extrusion forming mold
Tool includes the die head and pipe outlet section set gradually, and at 90~100 DEG C, the temperature control of pipe outlet exists the temperature control of die head
180~200 DEG C；
(3) tubing semi-finished product are checked, defective to be rejected, flawless, length is sawed on demand, into finished product graphite
Pipe..
The beneficial effects of the invention are as follows：The graphite-pipe of the present invention, both with corrosion-resistant, tension and compressive mechanical property, again
Substantially increase the electrical and thermal conductivity performance of graphite-pipe.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
