Agent, toughener, after mixing 30-40min, is prepared raw material A；
（2）Injection molding：By the above-mentioned raw material A being prepared by injection-moulding device injection molding, modified polypropene is obtained.
Further, the adiabatic agent is glass fibre；The toughener is polyvinyl acetal.
Further, the injection-moulding device includes lower die, the upper mold above lower die, between upper die and lower die
Demould column, the upper mold seat in upper mold, injection channel, the injection molding cavity in lower die and be removably arranged in injection molding cavity
Die holder；Operating cavity is equipped with the lower die, being equipped with part in the operating cavity penetrates to the anti-falling piece in the injection molding cavity, described
Die holder is equipped with and the matched anti-delinking part of the anti-falling piece；The lower die, which is equipped with, to be engaged with the anti-falling piece for releasing
Two assembling and dismantling handlers of the cooperation between the anti-falling piece and anti-delinking part, the two assembling and dismantling handler are symmetrical along the center line of the lower die
Set；The lower die is equipped with workpiece ejection piece and is equipped with the matched actuator of workpiece ejection piece, the die holder
The opening stretched out for the workpiece ejection piece.In the present invention by the cooperation of anti-falling piece and anti-delinking part realize die holder and injection molding cavity it
Between anticreep coordinate so that the outside diameter of die holder may be configured as the internal diameter for being slightly less than injection molding cavity, so that between the two will not be complete
In stuck state so that the dismounting of die holder relative injection chamber is more convenient；And there is provided the setting of attaching/detaching apparatus, it can control
By the state rapid translating of grafting anticreep to the state departed between anti-falling piece and anti-delinking part, consequently facilitating die holder can be quick
By being taken out in injection molding cavity, without prizing die holder by force, die holder is hardly damaged；, it is necessary to by lower die after workpiece injection molding
Demould and come out in seat, by the setting of workpiece ejection piece, can quickly realize the jacking operation to workpiece so that workpiece is in discharging
Directly depart from die holder, the demoulding is quick.
Further, the provision for disengagement includes one end lever piece matched with the anti-falling piece, another with the lever piece
The matched casting die in one end, act on reset components on the anti-falling piece and with the matched driving part of the casting die, it is described
Casting die outer end portion extend out to the lower die side wall to be engaged with the driving part；There is provided lever piece, so as to use
Lever principle driving anti-falling piece action, so that the active force acted on casting die easily can drive anti-falling piece to move without excessive
Dynamic, simple operation is laborsaving.
Further, the reset components are the stainless steel shrapnel that the multiple wavy shaped configurations being spaced apart are set；It is stainless
The sound construction of steel bomb piece, and return action power is big, so that when anti-falling piece and anti-delinking part coordinate, stainless steel shrapnel can act on
Larger pressure is on anti-falling piece so that the cooperation between anti-falling piece and anti-delinking part is stablized, die holder firm position.

Further, the lower die, which is equipped with, is used to jack up the jacking component of the die holder upwards, the casting die to by
During the nearly injection cavity direction movement, jacking operation can occur under the driving of casting die for the jacking component；By jacking component
Setting so that die holder can under the jacking of jacking component directly by injection molding cavity in stretch out so that without under when replacing
Die holder carries out prizing die holder, you can directly die holder taken, it is easy to operate, and it is time saving and energy saving, and die holder will not answer
To force to prize to damage, service life length.
Further, the jacking component is engaged including the jacking part below the injection molding cavity, with the jacking part
Driving member and with the matched impeller of the driving member；Described driving member one end is engaged with jacking part, and the other end is with promoting
Part is engaged；The impeller can push down on the driving member under the driving of casting die, and driving member can drive jacking part to move up
Jack up die holder；Impeller movement can be directly driven during casting die action, realizes the jacking operation of jacking component, and then works as and pulls
During hand, the disengaging of anti-falling piece and anti-delinking part can be synchronously realized, while realize jacking operation of the jacking component to die holder, without dividing
Step operation releases the operation of anticreep and jacking to realize respectively, and operation is more easy to be laborsaving；Without in addition setting actuator to realize
The jacking for jacking component is operated, parts are few, and failure rate is low；And the driving principle between impeller and jacking part is also lever
Principle, so that push piece need not act on power very big on driving member, you can realize the fast servo of jacking part, and jack dynamics
It is larger, be not in the situation that can not jack up die holder.
Further, there is the portion that arches upward, which is at least partly bent to form by the impeller on the impeller；
The casting die is engaged with the portion of arching upward, and the portion of arching upward has certain deformability, will when casting die is pressed into the portion of arching upward
So that the portion of arching upward is stretched, so as to promote driving member to act, you can realizes the jacking operation of jacking part.
Further, the workpiece ejection piece includes the body of rod and the arc panel with being connected in body of rod top, the arc panel
On be arranged with sealing ring；Arc panel can increase the contact area between jacking part and workpiece, be more easy to workpiece being lifted off die holder, and
Workpiece is not in the excessive situation of local pressure, is hardly damaged；Sealing ring can realize excellent sealing with opening, so as to avoid noting
Hot modeling liquid in the gap between opening and sealing ring by revealing downwards during modeling.
In conclusion the present invention has the following advantages：It is poly- by adding enhancing for graphite high degree in polypropylene
The corrosion-resistant and heat safe characteristic of propylene, prolongs the service life；Graphite and polypropylene and resin are enhanced using waste ceramic powder
Between polymerizing power so that polyacrylic intensity bigger, ball hardness number can reach more than 200；And waste ceramic powder is used and built
