Description of the Invention (1) [Industrial Use Field] The present invention relates to a reel for rolling up a metal wire, especially a wire for welding electrodes, wires, etc. After the object is rolled up, it is transported together with the object to be rolled up, or it is a reel for metal wire object winding, such as the use of the metal wire. [Previous technology] Generally, a reel for winding a thread is formed on the two ends of a circular drum with a graphic flange larger than the diameter of a circular drum, so that the thread can be stacked and wound around the circle. The outer periphery of the roller is provided for actual handling and use. The spool of the present invention is particularly suitable for winding wires such as electrodes and wires. For example, when it is used for welding rods, the coils that can be rolled up with a diameter of 5 to 2 5 kg are used for wire rods with a diameter of 0.8 to 2. 4 mm. "The coils for electrode winding are regulated.

Description of the invention (2) However, there is no lack of specifications regarding the material. Regarding such a reel, there is, for example, a reel for use in electrode winding disclosed in Japanese Patent Application Laid-Open No. 5 -2 6 2 4 5 9 whose main component is a polypropylene resin and contains 0.1 to 0 -5wt% talc Although polypropylene is cheaper, it is difficult to recycle. / Spools with polystyrene as the main component have been widely used. 'But for spools made of polystyrene or polypropylene, where the thread is rolled up', once it receives an impact from a drop hammer, etc. , The flange portion of the spool will be cracked or the shape of the spool itself will be changed. As a result, when the thread is exhausted, the process of winding the thread into the reel again will make it impossible to stack the coils in a row, or it will cause irregular crimps or formation. The paragraph (the upper coil is inserted between the lower coils) makes it difficult to output (or rewind) the thread when using the thread, which obviously reduces the productivity and workability, etc. Problems to be solved] In order to solve the above-mentioned problems, impact resistance additives are added to polystyrene, for example, a spool of 3 to 4% butadiene rubber has been developed, but its impact resistance is not yet It is sufficient, and there are no regulations to avoid the above-mentioned problems such as cracks occurring in the flange portion of the spool and the shape change of the spool itself. _Here ', the present invention takes into account the above problems, and provides a master paper rule that is widely applicable to the Chinese National Standard (CNS) Λ4 specification (210x 2W citizenship) I ...- 5-----.--- --I --- ^ ---_ ιΐτ ------ ^ (Please read the notes on the back before filling out this page) Printed by the Central Standards Bureau of the Ministry of Economic Affairs and Consumer Cooperatives A7 B7 V. Description of the invention (3 ) The reel is a reel for winding metal wire with good impact resistance and deformation resistance, which can be recycled. [Means for solving the problem] In order to improve the impact resistance and deformation resistance of the spool, the present invention has made in-depth discussions on the shape and material of the spool. In particular, it focuses on improving the characteristics of materials. That is, in order to obtain suitable characteristics as a reel for winding a metal wire, efforts have been made to develop a substance that improves the characteristics, thereby improving the characteristics. The bobbin for rolling up a metal wire according to the present invention is characterized by comprising a polystyrene having an average molecular weight (18 to 35) X104 and a resin having a rubber component of 5 to 15 wt%. The above polystyrene The most suitable average molecular weight is (2 5 to 3 5) X 1 0 4. In addition, the purpose of adding the above rubber component is to improve the impact resistance of the spool. For example, the rubber systems used are: polybutadiene (Poy butadiene), butadiene styrene rubber (butadiene styrene rubber), Butadiene acrylonitrile rubber, butadiene acrylonitrile rubber, chloroprene, acrylic rubber and other synthetic rubber. In particular, a butadiene-based rubber, that is, a so-called butadiene rubber is most suitable. In addition, the above forming system uses a cylinder diameter of 100 to 160.

The tensile strength is 400 to 6 50 kg f / cm2, the elongation is 1 to 3.5%, and the elastic modulus is (4 to 5) X 104 kg / cm2. However, the properties described above may vary depending on the degree of coincidence. Polystyrene is a colorless and transparent plastic resin. After injection molding, it can form various precise shapes with beautiful surfaces. If the average molecular weight is less than 18 X 10, the rigidity and rigidity will be greatly reduced, and the molded product will be easily broken. Therefore, from the viewpoint of impact resistance, the present invention uses polystyrene having an average molecular weight of 18 × 10 4 or more. Further, it is preferably 2 5 X 1 0 24 or more. On the other hand, the higher the average molecular weight, the higher the rigidity and strength. However, the more difficult it is to form, the more strain is caused inside the molded product. In addition, the impact value is also reduced. In addition, when the average molecular weight is 3 5 X 1 04, the effects of improving various characteristics will become saturated. Therefore, the average molecular weight is 3 5 X 1 04 as the upper limit. In addition, the average molecular weight of polystyrene can be based on the size of the polystyrene paper.

In addition, if the content of polystyrene is less than 80%, the characteristics such as the required strength of the spool will not be satisfied, and the deformation resistance will also be insufficient. Will decrease. Furthermore, the upper limit of the polystyrene content is set at 94% because the rubber, plasticizer and release agent must be added in a proportion of at least 6% or more. Rubber component: The content of rubber is about 5 ~ 1 5w t% ^ If the rubber component is increased, the rigidity of the molded body itself will be reduced. The decrease in rigidity will increase the rigidity of the molded product, and it will also have impact resistance. In addition, as the average molecular weight of polystyrene increases, strength and rigidity increase at the same time. Therefore, in order to meet the necessary strength and impact resistance of a reel for rolling up a metal wire, it is necessary to add a rubber component to a certain degree or more. In the present invention, it is possible to find out the amount of rubber to be added which simultaneously meets the requirements of the above-mentioned characteristics, and to overcome the problems existing in the conventional spools for rolling up metal wires. When the content of the rubber component is less than 5w t%, the strength and rigidity of the formed body are mainly affected by the average molecular weight of polystyrene. When the average molecular weight of polystyrene is small, the strength and rigidity are reduced. When the average molecular weight is large, the strength and rigidity increase.

Here, the lower limit of the content of the rubber component is 5 wt%. In addition, if the content of the rubber component exceeds 15% by weight, the particle size of the rubber will increase, but the rigidity will be lowered, which will cause the spool to break. Therefore, the content of the rubber component will increase. The limit is 15 w t%. Particle size of rubber: 1 ~ 10 kernels In order to make the reel for rolling up metal wires meet the characteristics of strength and impact resistance, the second method adopted here is to control the size of rubber. Within a proper range》 If the particle size of the rubber is in the range of 1 to 10 jam, and the amount of rubber added is less than that of a known person, the impact resistance will be satisfied. In addition, since the amount of rubber added is less than that of a conventional person, the possibility of reducing the strength due to the addition of rubber can be reduced. In addition, if the particle diameter of the rubber is less than 1, the effect of improving the characteristics cannot be achieved. Conversely, if the particle diameter is greater than 10, the strength will be reduced. That is, by adjusting the particle diameter to an appropriate particle diameter, As far as possible, the strength can be suppressed from being too low, and at the same time, the resistance can be improved, so that the characteristics of both impact resistance and deformation resistance can be satisfied.

Invention Description ( 7) It is extremely important for the polymerization time of polystyrene and subsequent stirring speed, especially the influence of the stirring speed on the formation of the rubber particle size. Method for manufacturing a molded body: The heating and melting temperature of the resin raw material is set to 2000 to 300 ° C. If the temperature is lower than 200 ° C, the resin raw material will not be melted. ○ If the temperature is higher than 300 ° C, the viscosity will be too low, which makes it easy to produce a bad shape after forming a solid. In addition, even if the heating and melting temperature exceeds 300 ° C, the characteristics of the formed body are not significantly different from the characteristics of the formed body in the temperature range of 200 ° C ~ 300 ° C. Therefore, the upper limit of the heating and melting temperature is 300 ° C. In addition, for the spool of the present invention, a plasticizer and a release agent are used as other formability modifiers. Among them, the plasticizer contains 0.1 to 5 wt%. »If the content of the plasticizer is increased, the heat resistance is reduced, and the molded product is likely to be deformed at high temperatures. Conversely, if the content of the plasticizer is reduced, the molding is performed. The internal strain of the product is prone to strain, which reduces the impact strength. That is, a small amount of plasticizer can reduce its rigidity. However, if it is added above a certain amount, the decrease in rigidity will be too small. In addition, in order to improve the release properties during molding, the weight percentage is included to about 0 · 0 5 ~ 0.2 (wt%) of a release agent such as an organic acid.

[Embodiment] Fig. 1 is a cross-sectional view showing a reel 1 of 20 kg in a rolled-up electrode according to an embodiment. Fig. 2 is a front view showing a spool. The outer diameter of the cylinder 2 is 150 mm. The outer diameter of the flange 3 is 270 mm. The distance between the flanges 3 and 3 on both sides is close to the inner center of the flange surface (the outer diameter of the cylinder 2) is 90mm ». Moreover, the flanges 3 and 3 on both sides are on the flange surface. The distance between the outer edges is 8 7mm before the electrode is rolled up, and 9 2mm after the electrode is rolled up. The flange 3 is provided with a plurality of radial reinforcing ribs 6. In addition, the center hole 7 is a through-cylinder in the long axis direction, and when the metal wire is rolled up or rolled back, the support shaft can support the spool through the center hole 7. In addition, the hole 5 is used to operate the spool. As shown in Table 1, a variety of materials are used to investigate the impact characteristics and tensile characteristics of the spool. For the impact characteristics, the I ζ 〇d impact test is performed. The impact strength was evaluated. In addition, regarding tensile properties, a tensile test was performed to evaluate the tensile strength. The I z 〇 d impact test method is based on ASTM D-256 [with notch, no heat treatment (exit X)], and the test is completed by the following steps. First, a test piece having a length of 63.5 mm, a width of 12.7 mm, and a thickness of 6 to 4 mm was produced by an injection molding machine. The paper size of the test piece applies the Chinese National Standard (C'NS). Λ4 is present (210 ^^ 7) while -11-J is installed. II II — Order — Line (please read the precautions on the back before reading) (Fill in this page) A7 B7 Printed by the staff of the Central Bureau of Standards, Ministry of Economic Affairs, and printed by the cooperative. V. Invention Description (9)-Calculated from the end of the central position in the length direction of 3, 1, 8mm control depth of about 2. 54 ± 0 0254mm and opening angle 45. The front end of the V-shaped groove with an arc angle of 0_ 25 feet. Secondly, it should be left for more than 16 hours in an environment with a temperature of 23 ± 2 ° C and a relative temperature of 50 ± 5%. In addition, an impact test was performed using an IzOd impact tester of 60 kg · cm / cm. And the impact elevation angle is 150. The test conditions are used to determine the impact value required when the test piece breaks. The tensile test is based on the test method of IS, and the test is performed under the environment of normal temperature. Table 2 shows impact characteristics and tensile properties. The No. 2 to No. 4 resin of the present invention has an I z 〇 d impact value of 9.8 to 14.5 kg f m / c m 2, which is obviously higher than that of the conventional No. 1 resin. In addition, although the impact value of the comparative example of No. 5 is higher than that of the conventional resin of No. 1, but because the rubber is added in a large amount, the tensile strength appears to be inferior to that of the present invention Nos. 2 to 4. Very low. That is, the maximum tensile strength that No. 5 can withstand is too low, and it is generally unusable. From this, we can understand the necessity of adding an appropriate amount of rubber. On the other hand, Table 3 shows that the weight percentage of the rubber amount was set to 8 wt%, and the particle diameter of the rubber dispersed in polystyrene was changed between 3 and 15 to investigate the impact of the particle diameter of the rubber on the impact. The influence caused by characteristics and tensile properties "As can be seen from Table 3, when the amount of rubber is constant, the size of the rubber is the size of the paper. The Chinese national standard (CNS) Λ4 specification (2 丨 0 X 297 cm) is applicable. ~.

The thinner the invention (1G), although the tensile strength will not change, the impact value can be increased. Therefore, if the rubber particle size of No. 8 is 15em, which exceeds the setting range of the present invention, the impact value is significantly reduced. Table 4 shows the results of the drop weight test of the spool. The test method is described above. The test line prepared 100 spools of resin having the composition shown in Tables No. 1 to 5 as shown in Figs. Welding rod (JIS: YGW-11) with a diameter of 1.2 mm. Actual product of 20 kg. "The drop weight test is a height of 500 mm calculated from the concrete floor, and the flange surface forms a horizontal posture, so that the test product is repeated. Three free-falls. After the test is completed, visually observe the break of the spool and the segment of the electrode (the upper coil is inserted between the lower coils). From Table 4, it can be seen that, compared with the spool of the comparative example of No. 5 made of the spool of the resin of the present invention No. 2 to 4, the cracks generated by the spool of the present invention and the Paragraphs (the upper winding line is inserted between the lower winding lines) are rare.
