Specifically, the graphene dispersing solution in step S1 is that ultrasonic disperse is made graphene in a solvent, and ultrasonic time is
1min~10min, ultrasonic power are 100w~3000w, which makes graphene uniform dispersion in a solvent.
Specifically, the solvent in the graphene dispersing solution in step S1 be water, N-Methyl pyrrolidone (NMP), dimethylbenzene,
At least two in ethyl alcohol, and the mass ratio of graphene and solvent is (3-5): 100, since benzene second can be added in graphene dispersing solution
Polymerization reaction is carried out in alkene, therefore the accounting of the graphene and solvent in graphene dispersing solution must control in a certain range,
Otherwise the dispersion effect that graphene is very few or the very few influence graphene of solvent is in thermal insulation material, so that thermal insulation material
Thermal coefficient and anti-flammability are bad.
Specifically, it is compound that common graphene product progress may be selected in above-mentioned graphene.It is also possible to modified graphite
Alkene.Modified graphene includes the one of which of watersoluble plumbago alkene, oiliness graphene, functionalization graphene, it is preferable that Neng Gou
Well dispersed functionalization graphene in organic solvent.
Specifically, polymerization reaction is 200rpm~3000rpm progress with mixing speed, and polymerization reaction is suspension polymerisation, is stirred
The effect mixed is the molecular weight that polymerisation of liquid droplets was fused together and influenced polymerization efficiency and product in order to prevent.
Specifically, dispersing agent is polyvinyl alcohol (PVA), hydroxymethyl cellulose (HEC), tricalcium phosphate (TCP) in step S1
At least one of, dispersing agent quality is the 0.1~15% of the styrene quality, and the effect of dispersing agent is to further protect

During answering, part reaction solution is taken to be cooled to, if reaction solution after cooling forms crisp and hard particle, polymerization reaction knot
Beam, cooling reaction solution, and isolate product.
A kind of preparation method for poly styrene composite material that the embodiment of the present invention provides, the preparation method is due to technique
Simply, reaction condition is mild and can be continuously produced, and can be applied to industrialized large-scale production.
The embodiment of the present invention also provides a kind of poly styrene composite material, and the poly styrene composite material is by above-mentioned any
One method is prepared.
The poly styrene composite material carries out polymerization reaction by the way that graphene dispersing solution and styrene is added, and is dispersing
Under the synergistic effect of agent, initiator and surfactant, so as to be dispersed in the polystyrene finally polymerizeing compound for graphene uniform
In material.
The present invention also provides a kind of thermal insulation material, which is foamed by above-mentioned poly styrene composite material and is made,
The thermal coefficient of the thermal insulation material reaches 0.027 ± 0.01W (mK)-1.The thermal coefficient of the thermal insulation material is more domestic excellent
The low 10%-15% of the thermal coefficient of styrofoam.Above-mentioned thermal insulation material is since graphene uniform is dispersed therein, so that graphene
One or more layers " protecting wall " is formed (in the continuous phase of polystyrene) in the thermal insulation material and plays what trap heat distributed
Effect.In addition, the thermal insulation material is since the lamellar structure of graphene itself densification of dispersed phase causes heat transfer to be obstructed, in turn
So that the thermal insulation material flame-retarding characteristic is promoted, reach GB8624-2012 B1Rank.

Poly styrene composite material in following embodiment is foamed by pentane, and thermal insulation material is made and carries out phase
Thermal coefficient and the flame retardant rating test answered.
Poly styrene composite material is the form of pellet before foaming.Wherein, poly- containing foaming agent in foaming process
Benzene composite material pellet can't foam before 80 DEG C, the hair being simply present in poly styrene composite material pellet
Infusion will not also be expanded to external diffusion, at this time poly styrene composite material bead formation.When temperature is greater than 80 DEG C, polystyrene is multiple
The pellet of condensation material starts to soften, and the foaming agent for being distributed in poly styrene composite material pellet interior is heated, and vaporization generates steam
Pressure causes the pellet of poly styrene composite material to start to expand and formed mutual disconnected abscess.Meanwhile steam pressure also seeps
Enter into these abscesses, increases gross pressure in hole.Over time, steam pressure deepens continuously, and pressure also constantly increases
Greatly, the volume of poly styrene composite material pellet also constantly increases, this process is sustained, and volume expansion can maintain
Until the rupture of abscess thin-walled.(wherein foaming agent is pentane, is heated to the pellet softening of poly styrene composite material until being formed
Abscess simultaneously constantly expands whole process maturing process).
