[Prior Art] In recent years, as the performance of optical information recording devices such as mobile cameras, DVDs, CDs, and MO drives has become higher, size has become smaller, and costs have become lower, there is a strong need to develop a It can even be used to record the excellent materials and excellent processes of optical components (such as optical lenses or filters) used in equipment. Plastic lenses are lighter and more resistant than inorganic materials such as glass, which can be added to various shapes and are superior in cost to glass lenses, making plastic lenses not only as spectacle lenses but also as optical components above. And become common. Due to this common miscellaneous, it has been a challenge to increase the refractive index of the raw material to reduce and thickness, reduce the linear expansion coefficient of the lens to prevent the thermal expansion of the light 1 and the influence of temperature fluctuations or the like. Taking a von item|To improve the refractive index of the lens and reduce the linear expansion number as described above, a thermoplastic nano-composite resin containing inorganic fine particles has been studied as a resin metal oxide fine particle for a plastic resin. The inorganic fine particles are evenly dispersed, and the Millennium Women 200940300,

j jpix.ClOC A conventional mainstream method of mass-production lenses for resin materials for plastic lenses is a method using injection molding or a method using hot press molding. In the manufacturing method using injection molding, as long as sufficient thermal fluidity can be applied to the resin material, it is relatively easy to obtain a uniform size, uniformity, and uniform optical properties by causing the resin material to completely fill the inner space of the mold. High quality lens. __ : ❹ ❹ However, since the nanocomposite resin generally has poor fluidity upon heating and cannot completely fill the wire (4), it is not suitable for use in, for example, the lens I see, for example, Japanese Unexamined Patent Publication No. 2 GG6-343387 The need for precision transfer of the components for injection molding.

[Invention] However, in the case where the powdery nanocomposite resin mold cannot be molded by hot press molding, it is difficult to control the resin material loaded in the mold to a uniform value. In the lens, the volume of the load For the lens size, it is called 敎, and thus in terms of optical properties, etc. 5 200940300 juozjpii.doc caused the problem that the situation caused a significant decrease in product yield. Ding Tian temporarily became a melted 11 nano-composite dragon formed by pressing pressure plus body And in the method of pre-forming the final lens shape for press processing by the hot charge system, the melted state of the nanocomposite tree::: six turns lower.

It is determined that given a 4, the domain is made up of a squad that is made into an aggregate in which the state of the powdered particulate material is maintained. In this way, the shape of the preform as the pressing force can be set to a shape close to the shape of the finished product, and a pre-form for processing which is more convenient for molding the product can be obtained. The above described features and advantages of the present invention will become more apparent from the description of the appended claims. [Embodiment] Hereinafter, preferred embodiments of a preform for retreading and a method of manufacturing the same according to the present invention will be described in detail with reference to the accompanying drawings. In the present specification, the numerical range indicating by using "to" indicates that - the values of "to, before, and after" are included as the range of the lower limit and the upper limit. Fig. 1 is a pressure according to one aspect of the present invention. A schematic view showing the structure of a first exemplary embodiment of a manufacturing apparatus for processing preforms. Fig. 2 is a schematic view obtained when viewed in the direction indicated by the arrow A of Fig.doc 200940300 1. The press processing according to the present embodiment The pre-formation ^2 fluidity and the size of the fine-grained frequency are the powder particles of the thermoplastic resin which is difficult to have inorganic fine particles in the extruder. The powder granule material of the particle diameter is supplied, : the case where the state of the powder granule material is maintained in the heat of seven, and the resin powder granule material 7 is extruded from the squeezing machine S to extrude the aggregate 23 in the squeezing Extrusion amount 2 In this paper, the nano composite resin powder particle material 7 is defined as a material in which each inorganic fine having a predetermined particle size is hardly uniformly dispersed in the thermoplastic resin, and the inorganic fine particles dispersed are The application has different particle diameters. For example, when the stomach is used as a powder particle material for an optical component such as a lens, the average particle size of the dispersed fine inorganic fine particles is directly set. For the range of nanometers to 15 nanometers. When the nano-composite resin powder granule material 7 is different from the application, the fine granules of the scattered _ _ _ granules are set to about 丨 nanometer to 300 nm. The nano-composite tree powder powder material 7 can be used by a powder obtained by completely mixing the money with the polymer and then forming the mixture into a powder, the mixture S being a mixture of inorganic fine particles and a powdery material of a polymer, which is obtained by physically mixing the powder, or a polymer powder (masterbatch) containing a high concentration of inorganic fine particles by stirring. A mixture obtained by mixing polymer powders containing no inorganic fine particles, which will be described later in more detail. As described above, when the state of the powdered particulate material is maintained therein When the nanocomposite resin powder particulate material 7 is gathered, the preform 21 for press processing and the aggregate 23 are in an opaque state. The extruder 1 shown in Fig. 1 includes a heating cylinder 3 having a nozzle 2 at its tip end. In the heating cylinder 3, there is provided for feeding into the heating cylinder 3

The material inside is directed toward the extrusion screw 4 of the nozzle 2. The heater 5 is attached to the outer circumference of the heating cylinder 3. A hopper 6 for feeding the nanocomposite resin powder particulate material 7 as a raw material into the heating cylinder 3 is attached to the proximal end side of the heating cylinder 3.

A powder supply device 3 is provided on the hopper 6, which is capable of feeding a fixed amount of the nano-resin powder particle material 7 to the hopper 6. In the bucket 6 , a vibration unit 6a is disposed at the side surface position to prevent the residual nanocomposite resin powder particulate material 7 from being removed by the vibrating unit 6a due to the occurrence of a 4-connection or the like, as long as it It is possible to prevent the remaining nanocomposite resin powder particle material 7 in the hopper 6. Because the part of the final ball bucket 6 that is in contact with the heating cylinder 3 will be self-heating, the resin powder surface (four) 7 may be fused to the part, so in the 杳: 部单凡6b' so that the nano composite resin powder particles # Feed into the heating cylinder 3. 1 At the rear end of the extrusion screw 4, a motor/deceleration device 9 is provided, the extrusion screw 4 is rotated to perform a squeeze rotation operation, and an input order is provided 12 200940300

j jpxf.d〇C element 8' is used for the resin pressure sensing thief 2a received in the tip end portion of the nozzle 2 to receive a signal to detect the squeezing pressure, thereby detecting the motor rotating load of the motor/reduction device & Further, a cutter ι is provided on the tip end of the nozzle 2 for cutting the aggregate 23 extruded from the nozzle 2 into a predetermined length. The extruder 1 comprises a type extruder "equipped with two sowing screws 4' arranged parallel to each other in the heating cylinder 3 and comprising a uniaxial type extruder equipped with an extrusion screw 4. It is preferable to use a biaxial type extruder in terms of suppressing the heat load of the nanocomposite resin powder particle material 7 and stably obtaining a uniform extrusion force. Further, when the resin material fed into the heating cylinder 3 is excessively pressed by the extrusion screw 4, the bonding between the powder particles is &, thereby reducing the fluidity as the aggregate 23. Therefore, it is preferable to use a twin-shaft type extruder having two extrusion screws 4 which rotate in the same direction, which suppresses the compressive force of the extrusion screw 4 and controls the compression force to a constant pressure. Further, by supplying a fixed amount of 奈 of the nanocomposite resin powder particulate material 7 from the powder supply device 3 according to the extrusion of the aggregate 23, the uniform extrusion force to the aggregate 23 can be more reliably and constantly stabilized. Further, since the extrusion screw 4 reduces the compressive force applied to the material during the rotation, the extrusion screw 4 preferably has a simple spiral groove structure in which the pitch between the spirals is constant or small, and it is preferable to avoid having a large The structure of the rotating fin (disk) or torsion fin. As the powder supplier 30, the vibrating type powder supplier can supply the nano composite resin powder particle material 7 most stably. However, any type can be used 13 200940300

A powder supply of 3UO/ipif.d〇C, such as a table type powder supply, a screw type powder supply, and the like - as long as the powder supply device can supply the solid nano composite according to the extrusion of the aggregate 23 The resin powder particle material 7 is sufficient. In order to stably supply the nanocomposite resin powder particle material 7 by the powder supply device 3, the nanocomposite resin powder ageing material 7 is preferably in a state of high fluidity as a powder' and is preferably provided, for example, by the base hair and Dry and obtained products. The atmosphere-removing aggregate 23 can be carried out by replacing the atmosphere at the place where the extruder 1 is placed with nitrogen. , the residual solvent, the low molecular volatile component or the volatilization of the vulcanized material in the hot extruded S ΐ granule material _, can be used in the afterburner, or the active component can be transferred more actively by reducing the hurricane hole == Composite resin powder granule material 7 nozzle 2 opening knives] surface configuration (mold configuration) package and similar configuration, and the profile configuration is not = wide two $, star configuration is can. When the mold __, 彳〃 可,! It is squeezed to a range of 4 mm. The diameter of the mosquito can be 〇.5mm mA by the nozzle ^ opening part has a circular cross section, the diameter is less than 05 millimeters (four), due to the opening π size is too small, ^ too much pressure, so that the aggregate. ~ Break the extruded U23 to apply the block. If the diameter is larger than 4 mm, the |1} 1 becomes a poorly accurate and accurate measurement accuracy. It is difficult to perform fine measurement adjustment and to change the pressure of the nanocomposite resin powder female material applied to the heating cylinder 3 to a range of about 0.55 dead pasto to 7.0 MPa. The number of revolutions per minute of the extrusion screw 4 is preferably in the range of about 50 rpm to 4 rpm. When the rotational speed per minute is less than 50 rpm, the speed of the rotating blades is lowered, which deteriorates the sharpness. When the number of revolutions per minute is more than 4 rpm, the extrusion of the aggregate 23 is unstable. As for the nano composite resin powder particle material 7 fed into the hopper 6, it is preferable to use a material which is simply fed into the nano composite resin powder particle material 7.

However, in order to improve the fluidity of the powdered granular material, a nanocomposite resin powder particle material 7 which is a mixture of paste cancer and a mixture of the nanocomposite resin powder material 7 and the liquid may be fed. Mixed to get. Further, the nanocomposite resin powder particle material 7 and the liquid can be separately fed to the heating cylinder 3, and either of them can be fed first. By preparing the dispersing liquid from the liquid in advance and mixing the dispersing liquid to the composite resin powder particle material 7 to prevent the powder from being placed around the surrounding environment in the feeding operation, and facilitating the fixing of the nano-composite resin powder particles. Material 7 is supplied into the heating cylinder 3. The liquid to be mixed is not limited as long as it is mixed with the powder particulate material, and the liquid mixture of water and alcohol is preferable in terms of dispersibility, operability (not necessarily explosion protection), and volatility. A dissolved powder can be used. However, in this case, it takes time to dry the added liquid. Therefore, the liquid for dissolving the powder is not preferable. In the liquid to be mixed, the liquid concentration is preferably not more than 50% by weight in the vicinity of the nozzle, and more preferably not more than 4% by weight. (In the description here, 2009-12300 ^uo^^pu.doc, the weight ratio is equal to the mass ratio.) When the concentration is too high, the paste state is made close to the liquid state, making the blade difficult to cut. Examples of the alcohol which can be used include methanol, ethanol, isopropanol, tert-butanol and the like. As a dispersing liquid mixture other than the dispersed liquid mixture shown above, dimethylf〇rmamide (DMF) can be used as the guanamine-based compound or N-methyl-n-pyrone (N-methylPyrr). 〇lid〇ne, ΝΜΡ). Further, acetonitrile, acetone, dimethylsulfoxide (DMSO) or the like can be used.

The temperature of the aggregate 23 extruded from the nozzle 2 is preferably in the range of the glass transition temperature Tg to Tg + l 〇〇 °C. #The temperature of the aggregate 23 to be extruded is lower than the glass transition temperature %•, so that the powdered particulate material does not become an aggregated state in which the powdered particulate materials are joined to each other due to the excessive temperature. When the temperature is higher than 18+1〇〇. At the time of enthalpy, the grain boundaries between the individual powder particles disappear and the fluidity is lost.

The inner glass transition temperature of the nanocomposite resin powder particulate material 7 used in the present embodiment is Tg H. Therefore, the temperature extruded from the nozzle 2 is preferably set to 85. 〇 to the range of 18n:. The extrusion temperature can be set to the same temperature from the powder inlet to the outlet, or the temperature at the outlet can be increased by about 1 Gt: to increase the fluidity of the material.

It does not contain blast drying, vacuum drying or similar drying, ί Not _ hemp. The concentration of (4) after the dryness is preferably set to not exceed 3 parts by weight. When (4) is high, there is a case where the subsequent pressure is 16 ❹ ❹ 200940300 juoz^pif.doc, or the situation of the mold failure after molding, and thus the high liquid; the agricultural degree is not preferable. Next, as shown in Fig. 2, by providing a degree on the circumference of the disk n, the cutting blade 12 of the fork is used to obtain the cutting; Although the assembly is squeezed from the opening portion of the mouth 2 at a strange speed, the cutter 12 is cut through the nozzle 2 at a given time interval = the set 23 is cut into a predetermined length for processing * Cutting plane J: In addition, it can be used around the 5 〇 tii I, the temperature is preferably maintained at the glass transition temperature, such as when the temperature of the cut edge is too low, the material temperature is reduced, so that high accuracy cannot be performed. When the cut 1 is broken in the present embodiment, when the pre-two nozzle 2 of the aggregate 23 is extruded, the cutter 12 is executed when the nozzle 2 is opened 2 2: '3 poly / f / 3 is in a gel state The aggregate 23 i is granulated.

When the fluidity obtained by the composite resin block is obtained in comparison with the state of use, a small gap can be used to obtain high fluidity, and when the lion body 21 for press-pressing is formed into a product shape by a heat rejection system, The preformed preform 21 can completely fill the inner space of the mold due to its flow (4) without uneven distribution of stress. Further, since the above-mentioned preform for press processing is a bulk of the aggregate', it has excellent operability (processability) and scalability, and can be easily performed during hot press molding. Yu Lin, who will load the resin material in the mold, will pay the value of the bribe. That is, during the hot press molding for forming a product, since the amount of the resin material loaded in the mold can be easily controlled to a uniform value, and the resin material loaded in the mold is allowed to completely fill the mold. The internal space allows stable production of high-precision resin molded products by hot press molding, and 19 200940300 3Ub23pif.doc to manufacture resin (4) products using inorganic fine plasticity.
