Taking the silver class plastic granules as an example, when the silver powder coloring process is carried out, the proportion of the silver powder is large, and it is easy to mix in the 1246957 process (4), and it is difficult to mix well with the plastic fluid, so that the TPE plastic grain tone is dyed. The color is not uniform, the dyeing effect is not good, and the finished product is easy to change color and yellow after long-term use, and affects the overall aesthetic appearance of the product. Moreover, due to the limitation of the conventional extrusion process, the particle size of the cut-formed TPE plastic particles is usually too large (about 6 _), and it is not easy to feed the plastic injection/cutting machine during the subsequent dyeing process, which affects the operation. Smoothness. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method of blending a thermoplastic elastomer pellet having a small particle size and a good dyeing effect and molding efficiency. Thus, the method for blending the thermoplastic elastomer particles of the present invention comprises a coloring master batch forming step, a chain mixing step, and a draw-shear forming step. In the coloring masterbatch molding step, a acrylonitrile-butadiene-styrene ethylene copolymer (ABS) and a polycarbonate compound (pc) are blended to form a plurality of coloring masterbatch, wherein the two are blended. The weight ratio (ABS/pc) is between =0.30. In the chain mixing step, the thermoplastic elastomer and the colored masterbatch are blended in a molten state at a weight ratio of 95 Å to 1 〇 50: 55 to 65. In the drawing and shearing step, the mixed material is sequentially drawn and cut into a plurality of cylindrical thermoplastic elastic shaped plastic products. The effect of the invention is that the coloring masterbatch is pre-formed, the thermoplastic elastic plastic and the colored masterbatch are stirred and mixed according to the predetermined blending ratio, and then the small particle diameter (about 3 mm) is sequentially drawn and sheared and Coloring effect 1246957 Fruit good finished product. The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to FIG. 1 and FIG. 2, a preferred embodiment of the method for forming a mixed-chain pelletizing method for thermoplastic elastomers according to the present invention comprises a coloring master batch forming step 1, a chain mixing step 2, and a drawing shear forming step 3. . In the coloring master batch molding step 1, a acrylonitrile-butadiene-styrene (ABS) and a polycarbonate compound (Polycarbonate, PC) are blended according to a predetermined ratio. The blending weight ratio (ABS/PC) of the two is between 0.05 and 0.30. Continue to feed the mixture into a plastic injection & cutting machine, first heated to a high temperature molten fluid state, with uniform mixing, so that the molten mixture is sequentially injected, conventionally extruded, cut into pellets, and cooled. The processing steps are such as to form a milky white colored masterbatch. Since the molding technology of the colored masterbatch is a traditional plastic processing and molding technique, it will not be described in detail herein. In this embodiment, ten grams of ABS and ninety grams of PC are respectively taken, so that the blended weight ratio (ABS/PC) is about 0.11; of course, 20 grams of ABS and 80 grams of PC can be taken, so that two The blended weight ratio is about 0.25. Next, in the chain mixing step 2, a thermoplastic elastomer (TPE), the colored masterbatch formed in the foregoing step, a coloring powder, an antioxidant, an anti-UV agent and a titanium dioxide nanometer are further The photocatalyst particles (particle size: 〇.〇9nm) were subjected to high-temperature stirring and mixing, and the mixture was in a state of 1246957^. #中, Thermoplastic Elastic: = Masterbatch: Coloring powder: The weight ratio of antioxidant m line agent is between 950~1050: 55~65^u 〇 · 2·5~3·5 · 3.5~4.5. This real one J 'take one kilogram ΤΡΕ, sixty grams of colored masterbatch, four grams of colored powder, two antioxidants' and four grams of anti-UV agent blended together, let plastic flexible plastic: coloring masterbatch: ·Anti-J agent: A wide range of anti-UV agents: then: 60:4··3:3. Further, the color of the colored powder is silver to be dyed on the colored mother particles 'to make the colored mother particles silvery; and the n particles are sufficiently mixed in the thermoplastic elastomer so that the mixture in the form of a dazzling fluid is also silver. Finally, in the drawing and shearing step 3, the silvery mixture of the molten fluid state obtained in the above step is guided to a person-drawing & cutting machine. After the mixture is fed to the drawing & shear forming machine, it will be continuously and uniformly stirred, and the mixture is drawn into a wire shape, and then cut into small particles by a male. Cylindrical granular shape, finished after the completion of the silver thermoplastic bomb 14 plastic finished product is prepared with anti-oxidation, anti-ultraviolet properties, and at the same time has a killing function. In this embodiment, the finished thermoplastic elastomer pellet has a size of 〇 X 4 (i.e., a particle size of 3 mm and a height of 4 mm). Therefore, the mixed-chain granulation molding method of the thermoplastic elastic granules can achieve the following advantages: 1. The thermoplastic elastomer granules are dyed uniformly, and the dyeing effect is good: using the pre-made colored masterbatch, and the thermoplastic elastomer, When the coloring powder is stirred and mixed, the colored powder can be easily and uniformly dyed on the colored masterbatch, and the colored masterbatch can be uniformly dispersed in the molten material in the melted form of 1246957, so that the mixture is present as a whole. A perfect and uniform color rendering effect 'The finished thermoplastic elastomer pellets with drawn and sheared shape have good dyeing effect, so that the finished products (for example, toys) are relatively uniform in appearance color. Therefore, it can effectively improve the TPE plastic particle inhomogeneous sentence in the conventional process. 'The dyeing effect is not good. This problem is due to the addition of human antioxidant, anti-UV agent and dioxide=nano light «grain'. (4) Difficult to play (4) The finished product has both mechanical and mechanical properties. It also has anti-oxidation, anti-ultraviolet and bactericidal effects. It can resist external environmental factors in long-term use, effectively maintain the original color tone, maintain the appearance of the product, and eliminate environmental odor. Effectively improve the TpE plastic pellets formed by the conventional process, which is easy to change color and yellow after use, and affects the aesthetics of the applied products. 2. The thermoplastic elastomer particles have a small particle size and are easy to apply: The thermoplastic elastomer particles are formed by the drawing and shearing technique, and the particle size of the plastic particles is effectively refined to about 3 mm, and the heat-forming type for subsequent applications. In the process of mixing and twisting, it is very convenient to effectively improve the conventional process. The particle size of the τρΕ plastic particles formed by the injection and extrusion technology is as high as six, and the subsequent twisting of the material is not easy, which affects the smoothness of the molding operation. In summary, the mixed-chain granulation molding method of the thermoplastic elastic granule of the present invention utilizes pre-formed colored masterbatch, and the thermoplastic elastomer and the colored masterbatch are stirred and mixed according to the predetermined blending ratio, and then sequentially drawn and sheared. It is possible to achieve the object of the present invention by cutting and molding a thermoplastic elastomer-plastic finished product having a fine particle diameter and a good coloring effect. The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent change of the patent application scope and the description of the invention is Modifications are still within the scope of the invention.
