Description of the invention (/) [Technical field to which the invention belongs] The present invention relates to a spinneret for spinning a molten resin such as polyester or nylon and a method for producing the same. < Please read the notes on the back before filling in this page) [Prior Art] For spinnerets, JP-A 9-300 0 4 2 8 will disclose the use of super hard materials or SKD, SK Η The bulk metals such as stainless steel, SK material, and stainless steel form spinning holes and discharge holes, and a diamond-like carbon coating film is formed on the surface to improve mold release, corrosion resistance, and abrasion resistance. In addition, Japanese Unexamined Patent Publication No. 9-1 7 6 9 1 1 discloses that the spinning holes and their peripheral portions are formed at least from ceramics, and that the thickness of the inner wall surface of the spinning holes is prescribed to be 0.15 or less. board. Furthermore, Japanese Patent Application Laid-Open No. 7F 8-7 4 1 1 5 discloses that at least the spinneret outlet and the vicinity thereof are covered with a TiN film, and an ion implantation layer of P is formed on the surface layer portion of the coating portion. Resin fusion is easy to occur, and the spinneret reduces the consumption of discharge holes. For this type of spinneret, the use of high-hardness, insulating ceramic materials for the spinnerets and processing holes takes a lot of time, and, In order to improve the processing of spinning holes and discharge holes, when using stainless steel or beacon steel, in order to improve the wear resistance of the discharge holes, a hard ceramic film is formed, and it is formed to improve the release property of the molten resin. Diamond-like carbon films, or the formation of TiN films, need to be implemented after the implantation of P ions, etc. As a result, increasing the manufacturing cost has to cause very expensive products. The characteristics required for spinnerets for molten resin spinning are based on the spinning holes. This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) A7 B7 455533 V. Expansion part and spinning hole of the invention description (&); The nozzle hole formed by the ejection hole has good abrasion resistance and can be used for a long period of time. It has low friction resistance with the molten resin, has good scrapability or mold release property of the molten resin, and molten resin during spinneret maintenance. Good mold release or washability. However, due to the fact that most of the spinneret materials are made of stainless steel and other metal materials, the wear resistance of the nozzle hole cannot be said to have the disadvantage of ending the life in a short time. In particular, fibers containing inorganic oxides or soluble salts such as fibers that emit far-infrared rays, antibacterial fibers, or UV-cut fibers have tended to increase recently. They are sometimes used because nozzle holes for spinning these fibers are worn faster. End your life once. Therefore, in order to prolong the life of spinnerets made of these metal strips, it is suggested that spinnerets like diamond plates and other hard films are formed inside the nozzle holes, and spinnerets that want to exert mold release or corrosion resistance. However, due to the spinnerets that form these hard films, the spinneret body is made of metal and metal. The thermal expansion coefficient is more than 1 〇 X 1 Q 6 / K, which is close to the thermal expansion coefficient of the resin is about 2 〇 X 1 0 6 / K, Therefore, the resin release property after spinning is inferior, and the washing property with the resin cannot be said to be sufficient. In addition, the diameter or width of the ejection hole is very small from about 0.1 to (3.3 m), and there is a problem that a hard film is not easily formed uniformly on the inner wall surface of the ejection hole. On the one hand, it is formed by using at least ceramics. The method for producing polyester fiber by a spinneret at the periphery of a spinning hole shows that the best ceramic contains fumed aluminum, and a ceramic material is particularly suitable, but alumina ceramic is more suitable. However, alumina ceramic material is suitable. When forming the spinneret, it takes a lot of time to process the nozzle holes, resulting in expensive manufacturing costs.

Therefore, the tetragonal metamorphosis with the wrong crystal phase evolves from a monoclinic crystal to a deterioration in strength and damage. The problem is that a long-spinning spinneret cannot be obtained (I. Moreover, although spinnerets made of ceramic materials are shown in patent publications and the like, there have been no successful users. That is, these ceramic spinnerets are forbidden. Forming a linear ceramic material, it takes a lot of time to form the nozzle hole due to the high hardness of the material. At the same time, static electricity is generated due to friction with the resin, which increases frictional resistance, and it has problems such as significant resin adhesion. The spinneret made of ceramics cannot be used for a short time due to thermal deterioration and cannot be said to have a sufficient wear resistance with nozzle holes. [Problems to be Solved by the Invention] The problem of the present invention is to achieve a molten resin. It has good scrapability or mold release, and good mold release or washability of the fusion resin. In addition, it provides ceramic spinnerets with a long life. Made from ceramic material to a spinneret, precision machining is easy to implement, cost reduction.

Description of the invention (4) Moreover, the present invention is made of ceramic materials The spinneret is formed with discharge holes of complex shapes and is subjected to electrical discharge machining under the important knowledge of the specific resistance near the surface of the material subjected to the pulse voltage and current when the so-called electrical discharge electrode is in contact with or close to the ceramic material. Ceramic material with high hardness, wear resistance, conductivity, and fine crystal grain size to form the entire spinneret or the nozzle piece for spinning (from the extension of the spinning hole and the spinning hole and the The reduced diameter portion of the spinning hole toward the discharge hole and the peripheral portion of the nozzle hole formed by the discharge hole) "That is, the invention also relates to a nozzle hole provided with a discharge hole formed by connecting the spinning hole and a small aperture in front of the spinning hole. Spinning spinnerets, at least with high hardness and abrasion resistance, Ceramic material, a molten resin is formed around the hole portion of the nozzle for spinning spinneret. Specifically, the ceramic material must have a Vickers hardness of 1,200 or more, a specific resistance of 値 0.1 Ω cm or less, a coefficient of thermal expansion of 10.0x 1 (Γ6 / κ or less, and an average crystal grain size of 2 // m or less. More than 99% of the theoretical density, there is no precision sintered body with voids of 2 V m or more, preferably 1 ym or more. By making the precision sintered body in this way, the phenomenon of molten resin immersing in the voids is eliminated, and as a result, the fusion resin fusion phenomenon When the entire spinneret or nozzle piece is formed from a green ceramic material like the previous alumina or hafnium type, the molten resin passes through the nozzle hole at high speed to generate static electricity to strengthen the resin. As a result, the adhesion force is equivalent to reducing the mold release property or washability of the resin.

However, the present invention uniformly disperses carbide or non-oxide-based conductive particles in alumina-based or alumina-based substrates. Therefore, a cutting powder adhered to a tool is equivalent to a powder that penetrates into a heterogeneous material and is thus cut into powders. The weak coagulation force reduces the clogging phenomenon, which can improve the processing efficiency of the nozzle hole formation. In addition, the specific resistance 的 of the ceramic material used is set to 0.1 Ω. Cm or less, and preferably 0. 05 Ω cm or less. This is because nozzle hole processing and sintered body electrical discharge processing are effectively performed at the stage of forming or temporarily sintered bodies by improving conductivity. The specific resistance 値 can be arbitrarily reduced by increasing the amount of the conductivity-imparting component in combination with alumina or a partial stabilizer pin. The specific resistance is the number measured by the probe method so that the probe contacts the surface of the material. According to the measuring principle of the four-probe measurement method, it is widely known. As shown in Fig. 5, four probes are arranged on the infinite test plane of the specific resistance, and the four probes are arranged on a straight line for pressure bonding. The needles at both ends are used as current electrodes, and the two insides are used as potential difference electrodes. When a current is passed from the current electrode, a potential difference V corresponding to the current I is generated. The relationship between this V, I, S and the specific resistivity is expressed in cm. Here, the S-type probe is spaced, and a commercially available device is made of 1 mm. [Represents additional current to the sample, and V represents the detection voltage of the measurement probe. In addition, the hardness and material strength of the conductive ceramic material of the present invention should be set to a Vickers hardness of 1200 or more and a bending strength of 7000 MPa or more. By satisfying this condition, precision processing and wear resistance of the spinneret can be achieved. .

Description of the Invention (^) In addition, for the ceramic material of the present invention, when using an alumina-based conductive ceramic material, its crystal grain size should be It is assumed that the crystal grain size of the oxidized brocade to form a base is 3 · 5 # m or less, preferably 2 β m or less, and the maximum crystal grain size is 7 " m or less. If the maximum crystalline particle size of alumina exceeds 7 μm, that is, when a discharge hole with a complicated shape is formed by electrical discharge machining of a steel wire, it is equal to that coarse particles prevent the steel wire belonging to the electrode from proceeding. Secondly, if the average crystal grain size of alumina exceeds 3.5 m, that is to say, the part detached from the alumina particles becomes a void during the forming process or discharge processing of the spinning hole and the discharge hole, and then the honing (Lapping of the nozzle hole) ) The process may leave voids. If there are voids left in the inside of the spinning holes and discharge holes or voids existing in the ceramic material, the molten resin is immersed in the voids or holes to prevent the mold release. In addition, for the conductivity-imparting component dispersed in the matrix, fine powdered carbides or nitrides or borides, or these mixtures or composites are used. When an alumina-based conductive ceramic is used, powders having a conductivity imparting component with an average particle diameter of 2 m or less and alumina powder with an average particle diameter of 1 A m or less are pulverized and mixed, and the raw materials for sintering to be uniformly dispersed are prepared after sintering. Powder, and can be obtained by performing Η IP treatment. In addition, when the formed body contains a forming aid such as stone gangue, it is degreased before the preliminary sintering ', and if necessary, it is interposed in a temporary sintering process. The average crystal grain size of the conductivity-imparting component dispersed in the material should be less than 3 am, preferably less than 2 / im, and by setting the maximum grain size to 5 jum or less, a material having no worse specific resistance than knitting can be obtained. In the state of a shaped body or a temporary sintered body, after grinding or sintering for forming nozzle holes, or grinding of this paper, the Chinese National Standard (CNS) A4 specification (210 X 297 mm) is applicable.

Description of the invention (7) Discharge In the processing process, since the voids detached from the particles can be removed by the final honing process, the tree fla has good demoldability, and a spinneret with excellent abrasion resistance can be obtained. (Please read the precautions on the reverse side before filling out this page.) "When using a zirconium-based conductive ceramic material as the ceramic of the present invention", uniformly pulverized mixed average particle diameter can be obtained by sintering after forming 1 " m In the following, the zirconium powder that is partially stabilized according to at least one of Y203 or Ce02 and MgO is the same conductive thief and ingredient raw material powder as those used to vaporize aluminum hafnium conductive ceramic materials. However, the raw material powder for sintering may be difficult to sinter due to the compound composition. Therefore, after forming the nozzle hole at the stage of the molded body at this time, the molded body is vacuum-sealed into a metal box and subjected to Η IP treatment to obtain a sintered body. In order to stabilize the zirconium part, the blending amount of the stabilizer is 1.5 to 5 m ο I% at Υ 2 ◦ 3, 2.5 to 7 mol% at ce 0 2, and at MgO, It is best to set it to 3-8 mol% of Fanyuan. Printed by the Shellfish Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs or a suitable combination of the aforementioned stabilizers to partially stabilize zirconium. Among these partially stabilized pins, a particularly excellent spinneret plate material can be obtained by using Y 2 0 3 partially stabilized pin powder with 1.5 to 5 m ο 1%. Here, the molded body is sintered so that the average crystal grain size of the pin base block becomes 1 # m or less, preferably 0,5 μm or less, and the average crystal grain size of the conductivity-imparting component is 3 am or less, preferably 2 // Below m. This kind of pin-type conductive spinneret material is actually composed of tetragonal crystals that form a zirconium-based crystalline phase, or most of the tetragonal crystals contain a small amount of monoclinic crystals. With the components being dispersed and strengthened, the spinneret material made of the previous zirconium-based ceramics at a spinning temperature of about 570 ° C changes from a tetragonal crystal to a crystalline phase in a short period of time, and the strength deteriorates. The dimensions are applicable to the Chinese National Standard (CNS) A4 specifications (210 X 297 mm) A7 B7 5 55 33 V.

In addition, the material composition in Table 1 shows the percentage capacity of the alumina (A1203) and titanium carbide (TiC), and the proportion of the sintering aid (Ti02) based on the total weight of (AI203 + TiC). The results of the investigation of the material properties of the spinneret are shown in the same table. ί Table 1 (※ Table 1 with a separate sheet inserted) When molding this alumina-based conductive spinneret material, a molded body obtained by molding a mixed powder of an oxide name and a conductive ingredient is formed. -1 2- This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) 55 33 A7 B7_ 5. Description of the invention (Please read the precautions on the back before filling in this page and form) In the state of formation, the spinning hole i and the threaded bottom hole of the ejection hole 2 with a diameter of 0.2 m are used. When the threaded bottom hole of the spinning hole 1 and the ejection hole 2 is contracted, the sintered spinneret material is processed in advance to Spinning holes 1 and discharge holes 2 are formed close to the finished product with a dressing allowance and a grinding allowance. Then, preliminary sintering is performed with non-oxidizing air to form S 5% or more of the theoretical density. The process obtained a refined sintered body with a theoretical density of 99% or more. Furthermore, a material of the composition No. 0.1 to 4 in Table 1 was used to form a spinneret member so that the diameter of the sintered discharge hole became 0.2 mm. , Followed by grinding of the periphery and both sides, and by Grinding is performed until the surface thickness of the end face of the discharge hole 和 and the inner face of the nozzle hole is 1 S to obtain a spinneret of the final product. This spinneret is used for juku spinning with i 0 2. Here, At a rate of 50 QQ in / min, using a discharge pressure of 2 8 MPa, the speed of the side extension and the exit speed. As a result, the cumulative service life of the spinneret of the previous stainless steel coated T i Ν was 100 hours, relative to The spinning spinnerets 1 Q of the composition No. 1 to 4 of the present invention are all 5 500 hours, which can achieve more than 5 times the spinneret life.

According to the process of forming, degreasing, pre-sintering, and IP treatment, the theoretical density of 9 9. 5 3S or more is obtained. By the way, the spinner material β, by the way, the sulfonated nickel if C is difficult to sinter, so the formed body forming the nozzle hole is vacuum-sealed into the metal box-1 3 " This paper size applies to China Standard (CNS) A4 size (210x 297 male ) Printed by A5 ____B7__ Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs of the Ministry of Economic Affairs of the United States (<Shi Shi IP treatment to obtain spinneret material. In addition, the material composition of Table 2 indicates the ratio of zirconium and Nb or WC The system capacity is%, and the proportion of the sintering aid (N b 2 3) is the weight% of the total amount of (ZrO 2 + NbC + WC). In addition, Table 2 shows the results of investigating the characteristics of the spinneret material. Table 2] (※ Table 2 inserted into a separate sheet) The entire spinneret shown in Fig. 1 was honed and repaired according to the composition No. 0.1 to 5 of Table 2 so that the diameter of the discharge hole was formed. 2 mm, and the surface thickness of the inner wall surface of the nozzle hole and the end surface 5 of the discharge hole side are formed for 1 s to obtain the spinneret of the final product. In addition, FIG. 6 shows the results of manufacturing test pieces having the same composition as those in Tables No. 2 and No. 3 in Table 2 and examining the thermal metamorphic deterioration of the zirconium component by heating in the air. In addition, in FIG. 6, for comparison, the thermal metamorphic degeneration property of 鍩 is stabilized with a Y203 portion of 2.5 m ο I%. This thermal metamorphism is degraded; the X-ray diffraction of the test piece can be performed according to the (m) plane [1 τ (in)] and the (] □) plane of the monoclinic zirconium [] The ratio of the diffraction high point of 1 μ (m)] to the diffraction high point height of the (m) plane [I μ (in)] of the monoclinic zirconium with a total height (monoclinic ratio%) is determined. That is, the larger the ratio of the monoclinic crystals, the more the thermal degradation occurs. The zirconium-based conductive ceramic of the present invention is characterized in that the heating time is 0% or less and the monoclinic ratio is 10% or less. In addition, the unit is heated at a temperature of 4 7 3 KK to 5 7 3 KK when heated for 2000 hours. The oblique crystal ratio is 40% or less. Moreover, the flexural strength of the test piece heated in the air at a temperature of 473 K is shown in Fig. 7.

Description of the invention (d) The linear method reduces the strength, and the conductive chromium material of the present invention is relatively to 2 0 0 0 The strength is not reduced after hours, and slightly reduced after 500 Q hours. This kind of thing indicates that at a spinneret using temperature of about 5 7 QK, a spinneret formed with partial stability errors undergoes thermal metamorphic deterioration in a short period of time, reducing Because of this, the strength cannot be used for a short period of time. On the one hand, the spinneret formed of the knotted conductive ceramic of the present invention has a very slow thermal deterioration rate, and hardly reduces the strength, so it becomes a long-life spinning that can be used for a long time. A spinneret was used. As a spinneret for spinning exactly the same as that of Example 1, the composition was N 〇1 to 5 of the spray plate 2 0 is still in a state of continued use even after the cumulative use time of 4 000 hours, understand the life of the spinneret for the spinneret coated with T i Ν on the stainless steel net The plate can reach 4 times or more. Moreover, the corner of the molten resin discharge corner is excellent in film release and abrasion resistance, so there is almost no rapid expansion of the discharged resin due to the kneading phenomenon or ballast effect. The time for maintenance of the spinneret is greatly shortened for reasons such as good demoldability and washability. Example 3 A spinneret material having the same composition as No. 2 in Table 2 was used, and processed into the form shown in Fig. 2 The shape of the nozzle plate 3 for spinning is inserted into a spinneret body metal 4 made of a metal strip material to obtain a spinneret 20. For the spinneret body 靥 4, it is used to have and composition N 〇 2 The material with the same thermal expansion pseudo number. In addition, the end face 5 of the outlet hole of the spinneret 20 is subjected to grinding or grinding or pear texture processing to perform the repair process so as to form the same flat surface to prevent the spinneret 3 Step difference from the spinneret body 靥 4 (bump :) However, the nozzle piece 3 formed of ceramic material is set into a stainless pin for spraying. 1 5-This paper size applies to the Chinese national standard < CNS) A47 (21ϋ X 297 mm) IIIIIII Tj I Ε t IIY .1 丨 liili- " D · ————-···· ^^ (Please read the precautions on the back before filling this page) b 5 3 3 A7 B7 V. Description of the invention In the conventional spinneret 20, since the thermal expansion coefficients of the nozzle sheet and the metal of the spinneret body are very different, the molten resin enters the sleeve part to float the nozzle sheet during use, and therefore has problems such as being unusable for a short period of time. However, according to the nozzle plate 3 of the present invention, since the thermal expansion coefficient of the spinneret body metal 4 is almost the same, the gap of the sleeve portion will not be generated even if the heating is performed at the spinning temperature, and the step of the discharge side end surface will not be generated. In addition, the mold release property is also good, so that the scraping of the molten resin at the start of spinning can be easily achieved. Example 4 Except for Y-shaped or cross-shaped or semi-cylindrical ejection holes formed by the complicated shape of the spinneret, various shapes have been proposed. For the method of forming the ejection holes with a complex shape, discharge is usually used. Machining or electrical discharge machining of steel wires. In this embodiment, as an example of a spinneret having a discharge hole having a complicated shape, an example of effectively forming and processing the Y-shaped discharge hole shown in FIGS. 3 and 4 (a) is as follows: In FIG. 4 (a), W The width of one side of the Y-shape, L represents the length of one side.

Especially The inner wall surface and surface thickness of the discharge hole of the ultra-precision milling machine are formed into a 1S0 spoon pear-shaped texture, and because the spinning holes are also super-precision drilled, the surface roughness can be made into an IS pear-shaped texture. Therefore, it is not necessary to perform honing of the inner wall surface of the nozzle hole, and it can be used as a spinneret as before. Since the spinneret made of stainless steel is worn quickly, it is necessary to roughen the surface of the nozzle hole in advance at the new stage. The degree is set to 0.5 S or less, but due to the spinneret of the material according to the present invention, it is wear-resistant Excellent damage, so even if the surface thickness is 1 S, but when used fast, it is equivalent to maintaining a better surface thickness than the previous spinneret.

F. Due to the total processing time required for threaded bottom hole processing and discharge hole processing and discharge honing and refurbishing honing processing, the ceramic spinneret becomes a very short time compared with the previous ceramic spinneret, so it can provide a low cost spinneret. G 'Because the entire spinneret or nozzle piece (including the peripheral part of the nozzle hole of the spinning hole and the ejection hole) is formed of a conductive ceramic material, it does not peel off like the previous spinneret that covered the inner surface of the ejection hole with a hard film Hard film. Η, compared with the previous stainless steel or stainless steel coated spinneret TiN can achieve several times the life.
