3. a kind of processing method of fireproof aluminum-plastic board according to claim 1, which is characterized in that the fire retarding synergist packet Include one of zinc borate, antimony oxide, sodium antimonate, zinc oxide or any several mixtures.
4. a kind of processing method of fireproof aluminum-plastic board according to claim 1, which is characterized in that the stabilization aid includes One of steady agent of surface treating agent, lubricant, interface modifier, antioxidant, light or any several mixing.
5. a kind of processing method of fireproof aluminum-plastic board according to claim 1, which is characterized in that the grain of the aluminium hydroxide Diameter is 20 nanometers~10 microns.
6. a kind of processing method of fireproof aluminum-plastic board according to claim 1, which is characterized in that rotor in the mixer Revolving speed is 800r/min, mixing time 60min.
7. a kind of processing method of fireproof aluminum-plastic board according to claim 1, which is characterized in that squeeze out in embryo material step and squeeze The mixture after kneading is put into feeder pipe when in use by equipment out, and mixture is entered in machine barrel by square key slot, condenser pump Condensation box house is cooled down by condenser pipe, cold air is entered in cover half shell by water absorption layer, and air blower is by cover half The intracorporal cold air of shell is drained into machine barrel by Air Filter, carries out cooling processing, while cylinder output to inside machine barrel Air-leg is driven to move up and down, air-leg cooperation telescopic rod drives connecting plate to move up and down, and then two sides is driven to condense pipe surface Sliding sleeve move up and down, and then condense pipe surface generate frost wiped, driving motor output shaft drive driving wheel rotation, Driving wheel moves driven wheel rotation by belt driving band, and driven wheel drives the first drive rod rotation, and the cooperation of the first drive rod is slowed down Device drives the second drive rod rotation, and the second drive rod drives conical screw rotation, pushes mixture to prolong machine when conical screw rotates Tube inner chamber is mobile, and the block of conical screw outer peripheral surface sufficiently squeezes the mixture in moving process in pushing course, most Mixture is extruded into embryo material by going out die head by whole conical screw.
