Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a method for recycling high-temperature nylon and a method for producing the same, which utilizes recycled high-temperature nylon (PA6T) and PA6 material and PA6 The -CO-PA6T copolymer is kneaded to form a PA6T/6 material. [0002] [Previous technology] High temperature nylon (PA6T), high temperature (long-term working temperature 180 ° C, short-term 280 ° C), high hardness, good toughness, good fluidity, wear resistance, insulation, anti-corrosion, suitable for injection molding A variety of thin-walled electronic and electrical components, connectors, and substrates for light-emitting diodes. Since the high-temperature nylon is a high-priced raw material, the value of the recovery is south, but the range of use is limited because the hardness of the nylon in the south is not easy to process. Therefore, it is imperative to seek a method for recycling and recycling high-temperature nylon, and the invention has been produced through multiple experiments. SUMMARY OF THE INVENTION The present invention is to solve the problem that the current high temperature nylon (PA6T) cannot be effectively recycled and reused. Accordingly, the present invention is mainly directed to a method for recycling high temperature nylon, which comprises: A. Recycling waste material of PA6T (semi-aromatic polyamide). B. Melt the waste. C. Add PA6 (polyhexylamine) material and PA6-CO-PA6T copolymer. D. Perform mixing. 099110672 Form No. A0101 Page 3 of 8 0992018775-0 201134859 Ε·Formed PA6T/6 (semi-aromatic polyamide) material. The above step D is carried out by a single screw extrusion molding machine or a twin screw extrusion molding machine. Above? The weight percentage of person 61' is 50% to 79.5%,? The weight percentage of 46 is 19.5% to 35%, and the PA6-CO-PA6T copolymer is 1% to 15%. After the above steps, the 6Τ/6 material is further molded into plastic pellets. The present invention provides a Τ6Τ/6 material produced by the above method for recycling high temperature nylon. The invention has the following effects: 1. It can recover resources effectively, can save costs, and has an environmental protection concept. 2. After molding, the 6Τ/6 plastic pellets are conducive to subsequent processing. For example, depending on the ratio of 6Τ and ΡΑ6, it can be made into a chair with a higher hardness and a plastic chair with a lower hardness. 3. The composition ratio of the present invention can be adjusted according to the softness of P A 6 Τ / 6 required by the user. [Embodiment] The present invention mainly provides a method for recycling and recycling high-temperature nylon, which comprises: A. recycling waste material of PA6T (semi-aromatic polyamide); recycling various thin-walled electrons , electrical components, connectors and substrates of light-emitting diodes, remove parts of other materials. B. Melt the waste; remove and clean the completed PA6T waste. C. Add PA6 (polyhexylamine) material and PA6-CO-PA6T copolymer 099110672 Form No. A0101 Page 4 of 8 0992018775-0 201134859; use PA6-c〇-PA6T copolymer as PA6T and PA6 Compatibilizer. D. Perform kneading; knead with a single screw extrusion molding machine or a twin screw extrusion molding machine. E. Form PA6T/6 (semi-aromatic polyamide) material. The above PA6T is 50% by weight to 79.5% by weight of PA 5% to 5% by weight. The PA6-CO-PA6T copolymer is from 1% to 15% by weight. The proportion of the component of the invention can be adjusted according to the softness of the PA6T/6 required by the user, for example, the chair frame of the office chair has a higher hardness, so the proportion of the component of the PA6T can be adjusted higher, or the plastic chair can be molded. The hardness does not need to be too high, as long as the proportion of pA6T is reduced, the relative 'PA6T composition will affect the composition of pA6 and PA6-CO-PA6T copolymer, but the proportion of the three components is as long as Within a reasonable range of values. In addition, the PA6T/6 material of the step E can be formed into a plastic pellet, which is advantageous for subsequent sales and processing. However, the above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention. The feature of the present invention is that the re-creation of the use of the technical means and the creation principle of the present invention is still within the scope of the invention. Therefore, the statements of the present invention and the description of the present invention are not intended to limit the scope of the present invention; any change and modification made by those skilled in the art without departing from the spirit and scope of the invention should be Within the scope of the patent.
