Field of the Invention The present invention relates to a manufacturing apparatus of a composite material and a method of manufacturing the same, and, in particular, to a manufacturing apparatus of a magnesium-carbon nanotube composite material and a method of manufacturing the same. [Prior Art] Magnesium is one of the most abundant light metal elements on the earth. Magnesium has a specific gravity of 1.74 grams per cubic centimeter (g/cm3), only 2/3 of aluminum, 2/5 of titanium, and steel. 1/4, it has the advantages of specific strength, specific stiffness, good shock absorption and noise reduction performance, good casting performance, abundant reserves and easy recycling. It is known as “the green engineering material of the 21st century”. Therefore, magnesium alloys can play a greater advantage in this respect. Due to its special properties, it is widely used in the aerospace industry, the automotive industry and the information industry. However, the cast magnesium alloy has weak points such as low absolute strength, soft texture, and poor high temperature performance, so that the magnesium alloy can only be used to manufacture parts such as shells that cannot withstand large loads. The town-based composite material has higher specific strength and specific stiffness, and may also have better wear resistance and high-temperature performance. Therefore, magnesium-based composites have greater potential applications than magnesium alloys. The prior art mainly improves the strength and toughness of the magnesium-based composite by adding a nano-sized particle reinforcement to the town-base composite. 0-1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Nailai (nm) 8 200911416 - Straight 彳 two and up to 100 micron (# m) length. These materials have a tensile strength of 100 times that of steel, a density of 丨·35g/cm3, a low expansion ratio, good thermal conductivity, electrical conductivity, and good slidability. They are ideal nano-whisker reinforcing and toughening materials. A typical process for adding the above-described nano-sized particles to a magnesium-based composite material is a semi-solid forming process. The semi-solid forming process mainly consists of die casting and thixotropic injection molding. Since the magnesium-based composite ingot is easily oxidized and burned in the human hot day, the prior art mainly uses the thixotropic left-beam forming process to prepare the magnesium-based composite material. The specific process for preparing the magnesium-based composite material by the thixoforming injection process is as follows: the substrate is processed into fine particles, and the reinforcing particles are added at the same time, the mixture particles are charged into the hopper, and the argon gas is used for protection, when the composite material particles are transported. 2 When the heating part is 'will be partially melted, the semi-solid material with the structure of the touch f is formed. Under the action of the spiral body, when it accumulates to a volume of one day, it is injected into the south and has been pumped out. Hot mold, into open 7 In the whole process of thixo-injection molding, magnesium-based composite material ^ is formed like a thermoplastic flow, clean, safe, the original material / xiao consumption is greatly reduced and no (four) is produced, less need The process of smelting liquid T and winding is carried out, and the formed parts can reach a high precision, and the shrinkage V' density is high. The carbon nanotubes as a reinforcement of the magnesium-based composite material can exhibit the strength and the secret of good t, so the magnesium-nano carbon nanotube composite y has excellent comprehensive mechanical properties. However, in the magnesium-based carbon nanotube composite prepared by the above-mentioned half-forming process, there is a problem of uneven dispersion of the carbon nanotubes in the 2009 20091616 (see, Development of novel carbon nanotube reinforced magnesium nanocomposites using the powder metallurgy) Technique, CS Goh et al., Nanotechnology » vol 17, p7 (2006)). Due to the uneven dispersion of the carbon nanotubes in the magnesium-nanocarbon nanotube composite, the magnesium-based carbon nanotube composites did not meet the expected requirements in terms of strength and toughness. Therefore, it is indeed necessary to provide a magnesium-based carbon nanotube composite material manufacturing apparatus and a manufacturing method thereof, and the carbon nanotubes in the magnesium-carbon nanotube composite material prepared by using the manufacturing apparatus are uniformly dispersed, and The magnesium-nanocarbon tube composite has excellent strength and toughness

When the hybrid body 91 is heated, since the screw rod 56 is continuously rotated and disturbed in the heating barrel 51, the four-segment of the rice is distributed in the thixotropic state (four) 92. Preferably, the heating tank is filled with an inert gas to prevent oxidation. The insulating layer 55 provided on the heating belt 54 may The thixotropic slurry 92 formed in the heating drum 51 during the heating process is not cooled too fast. (4) The slurry 92 is sprayed into the die-casting mold 6, and after cooling, it is formed, and the magnesium-carbon nanotube composite is formed. Material 9. The slurry 92 is sprayed into the die-casting mold 6, and the slurry 92 in the heating tub 51 is sent to the nozzle 53 by the injection of the screw %, and is sprayed into the die-casting mold 6 and filled. Die-casting mold 6; after cooling, a town-carbon nanotube composite material 9 is formed. It can be understood that the manner of spraying the slurry 92 into the die-casting mold 6 described in the present technical solution is not limited to the embodiment. Through the rotation of the screw 将, the thixotropic slurry 92 is sprayed into the die-casting mold 6; it can also be used to spray the thixotropic slurry with a spray 类似 similar to the spiral pre-plasticizing spray device used to bind the resin. 92 is sprayed into the die casting mold 6. In the method of preparing the magnesium-based carbon nanotube composite material 9 by the above-mentioned manufacturing apparatus, the negative ink produced by the suction pump 72 is used to treat the magnesium particles 3 and the carboniferous tube 4 The suction hopper 71 is mixed, and during the suction process, the magnesium particles 3 and the carbon nanotubes 4 continuously collide in the pores of the γ-type wheel tube, thereby forming magnesium particles 3 and a uniform dispersion of the nanotubes in the hopper. A mixture of 91. In addition, in the embodiment of the present technical solution, when the suction pump 72 is used for inhalation, a negative pressure of 15 200911416 is generated, and the magnesium particles 3 and the carbon nanotubes 4 are sucked into the hopper 71, and the first switch 阙 751 and The second switch chamber 752 intermittently adds a human-quantitative mixture 91 to the hopper, thereby ensuring the normal operation of the thixoforming machine 5, but without causing a large amount of the mixture 9 to be accumulated in the hopper 71. The manner of feeding the hopper 71 to the hopper 71 prevents the segregation of components in the mixture 91 due to the large difference in density between the magnesium particles 3 and the carbon nanotubes 4. In addition, the technical solution can also continuously suck the mixing body 91 into the hopper 71, and by controlling the sizes of the first switching valve 751 and the second switching valve 752, thereby ensuring that the thixoforming machine 5 is in normal operation and does not accumulate The mixture 9W is in the form of a mixture of the large read lock particles 3 and the carbon nanotubes 4 in the conventional secondary hopper 71, and the pot is easy to accumulate a large amount of the mixture at the hopper, and in the above A larger axis is generated in the mixture. Therefore, the technique of the present invention can effectively prevent the mixture of the magnesium particles 3 and the tube 4 from being added to the bucket 71 after the magnesium particles 3 and the carbon tube 4 are sucked into the hopper 71. Produce component segregation. After the above-mentioned mixture of the magnesium particles 3 and the carbon nanotubes 4 enters the heating barrel, the rotation of the screw 56 in the thixotropic state is disturbed, and the slurry of the carbon nanotubes 4 in the thixotropic state is 92. The distribution in the middle is further homogenized' so that it is sprayed into the house scale mold and 6铉, shape #某—太#^人二, 4 不米碳管4 is evenly dispersed and secretly (4) composite material 9. Since the carbon nanotubes 4 are uniformly dispersed in the magnesium-based carbon-compound carbon composite material 9, the advantages of the nano carbon material mixture and toughness prepared by the manufacturing equipment are good. /, negative intensity between 16 200911416 In summary, the present invention has indeed been proposed to shoot.
