Description

It is a kind of to utilize the method that prepared by graphene microchip to spray formula airslide disintegrating mill
Technical field
The present invention relates to grapheme material field, and in particular to the preparation method of graphene film, more particularly to a kind of profit With the method for preparing graphene microchip to spray formula airslide disintegrating mill.
Background technology
Graphene is the another Novel Carbon Nanomaterials being found after CNT, and its appearance makes the crystal knot of carbon The integral framework including fullerene, CNT, graphene, graphite and diamond has been configured to, has been established from zero to three The carbon normal form of dimension.Because graphene possesses excellent electricity, mechanics, optical property so that the preparation technology of graphene always with To receive much concern, the main technique that graphene is prepared at present is to take vapour deposition process, is decomposed at high temperature using gaseous carbon source The catalytic growth on matrix surface prepares graphene afterwards, and this method prepares high-quality and large area single-layer graphene Important method.But its working condition is more harsh, power consumption is big, and cost is high.Moreover, directly using gaseous carbon sources largely Add the danger of production.And another method for using graphite oxide reducing process to prepare graphene, mainly by graphite Strong oxdiative processing is carried out, obtains after graphite oxide, then stripping is carried out to it preparing graphene oxide, reduction treatment is eventually passed and obtains To graphene;But it is due to that the preparation method can destroy in graphene-structured, and preparation process that energy consumption is big, efficiency is low, cost High and pollution environment, it is difficult to promote.
Chinese invention patent application number 201310097659.9 discloses the preparation method of graphene, including:By graphene Presoma and amine compound are well mixed, and ball milling obtains well mixed graphene for 8~20 hours and mixed with amine compound Graphite presoma is peeled off using amine compound in powder, wherein ball milling and obtains graphene, the graphite presoma and amido The mass ratio of compound is 1:(1~10);, will be aminated by the graphene and amine compound mixed-powder dispersion solvent Compound dissolves;Filtering, graphene wet-milling is obtained using solvent washing filter cake;And the graphene wet-milling is placed in vacuum done In 60~120 DEG C in dry case, dry 5~12 hours, graphene dry powder is made.The preparation method technique of the invention is simple, process It is easy to control, but the graphene quality prepared is uneven, it is difficult to ensure that repeated.
Chinese invention patent application number 201410286173.4 discloses a kind of preparation method of graphene, and it includes following Step:(1)Graphite oxide is broken into fractionlet with the mode of mechanical shearing or ball milling;(2)Under hydrogen nitrogen or hydrogen argon atmospher, press Hydrogen volume concentration is 1~19%, and the concentration of nitrogen or argon gas is 99~81%, and gas flow rate is 10~100mL/min, with 5~ Above-mentioned graphite oxide fractionlet is warming up to 250~500 DEG C by 35 DEG C/min heating rates, and soaking time is 5~120min, hydrogen nitrogen Or hydrogen argon gas flows down and is down to room temperature or naturally cools to room temperature, obtains graphene.The preparation method of the invention is simple to operate, obtains Graphene reducing degree it is higher, but prepare graphene dispersion it is poor, quality is uncontrollable.
Chinese invention patent application number 201410226056.9 is disclosed prepares graphene using air-flow crushing stripping means The technique and device of presoma two-dimensional nano graphite powder, the invention device include air supply system, crush stripping system and gas-solid point From system;In stripping system is crushed, the material that A return ducts, B return ducts and tedge constitute air-flow crushing stripping process is followed Loop back path;A air entraining pipes, B air entraining pipes and C air entraining pipes constitute the air-flow crushing passage of air-flow crushing stripping process.Prepare graphite Alkene presoma two-dimensional nano graphite powder carries graphite particle jointly using three bursts of supersonic jets, by the collision of strip jet with Friction, realizes that high-purity crushing of graphite particle, with peeling off, continuously crushes stripping by the circulation of graphite particle, is derived from two dimension Nano graphite powder.The invention realizes the crushing and stripping of graphite powder using the mutual collision between graphite particle with friction, obtains High-purity two-dimensional nano graphite powder, but the preparation method low yield of the invention, product quality is uncontrollable.
Mechanical stripping method be it is a kind of can be existing frequently-used in inexpensive, the pollution-free method for preparing high-quality graphene Mechanical-physical stripping method includes conventional ball mill, stirring ball-milling, grinding etc., but during abrading-ball grinding graphite, due to part Apply pressure big, powerful impulsive force can make graphene produce fault of construction, the size of graphene after reduction is peeled off.Therefore, send out A kind of bright preparation technology is simple, and production safety environmental protection, production cost is low, and yield is high, the stable graphene preparation side of product quality Method, the application to promoting grapheme material, promotes the development of graphene industry significant.
The content of the invention
High for current graphene production cost, preparation technology is complicated, the small shortcoming of yield, the present invention propose it is a kind of it is low into The method of this preparation graphene microchip.This method utilizes equal in 500-200 layers of distribution to the spray formula airslide disintegrating mill preparation number of plies Even graphene microchip, the graphene microchip of preparation can be applied to the composite woods such as rubber, plastics, coating, lubricating oil, sewage disposal In material, or as the raw material for further preparing graphene, the preparation cost of current graphene can be greatly reduced.
