example, polyester, glass fiber, aromatic ester amine fiber, steel, carbon fiber, pB0 fiber, or the like. Most preferably, the thermoplastic elastomer is a thermoplastic polyetherester elastomer. The aforementioned thermoplastic polyether ester elastomer is a copolymer including an aromatic polyacetate (crystalline phase (hard segment)) and an aliphatic polyacetate (amorphous phase (soft segment)). The aforementioned hard segment may be an aromatic polyester having a high melting point, and is excellent in performance because it has a high crystallization speed, high strength, heat distortion resistance, good moldability, chemical stability, and heat aging resistance. In addition, the aforementioned soft segment may be an aliphatic polyester having a low glass transition point and is excellent in performance because it has flexibility, high impact absorption, and low temperature characteristics. In addition, a polyester having a suitable ratio of a hard segment to a soft segment may be disregarded to take advantage of the above characteristics. The toothed belt constructed by this method has the advantages of quietness, impact resistance, impact elasticity, low-temperature flexibility, bending strength, environmental resistance (low volatile gas) and food hygiene. As the thermoplastic elastomer, a thermoplastic polyurethane elastomer can be used for the aforementioned toothed belt. The aforementioned thermoplastic lysamine elastomers include polyesters and polys, and include soft and hard segments. The aforementioned soft segments include polyethylene adipic acid, polybutylene adipic acid, other adipic acid esters (^ p), polycaprolactone (PCL), polycarbonate (ρ0 or other aliphatic polyester Alcohol, polytetramethylene scale ethylene glycol (PTMG), polyethylene glycol (peg), polypropylene glycol (ppg) or other aliphatic polyether glycols or other polyols (long chain glycols) ). The aforementioned hard segment includes a diisocyanate and a short-chain diol. If the soft segment includes a polyester polyacryl compound (such as polyethylene adipic acid), polybutylene adipic acid, and other adipic acid esters ( ADP), polycaprolactone (PCL), polycarbonate (pC) or other aliphatic polyester diols, can obtain thermoplastic polyurethane elasticity with excellent mechanical strength, heat resistance, abrasion resistance and chemical stability On the other hand, if the aforementioned soft segment is polytetramethylene ether glycol (PTMG) or other polybasic compound, a thermoplastic polyurethane elastomer having excellent water resistance and low temperature characteristics can be obtained. For MDI-based thermoplastic polyurethane elastomers using aliphatic glycol chain extenders as the aforementioned hard segment, if When the length of the chain extender is extended, the bonding density between 200404964 and the chain will decrease as well as physical properties. The use of this button-shaped wire has the advantages of anti-wearing, resistance to recording, and back rotation (due to high μ). The hardness of the aforementioned thermoplastic elastomer can also be about A70 to A95 (jis "6253. The toothed belt formed by this method has the advantages of excellent flexibility, durability and high load performance. In the present invention The toothed belt is formed to prevent the thermoplastic elastomer from leaking out of the toothed surface side from the position where the protective fabric is woven and expanded. When the toothed belt is running, it is exposed to the surface of the toothed belt easily. Moreover, it is deposited on the bottom of the aforementioned pulley, which will cause poor shouting, the aforementioned anti-beating degradation, durability reduction and abnormal noise. In addition, another object of the present invention is to provide a method for manufacturing the aforementioned toothed belt, wherein the aforementioned The toothed belt can resist the resin from oozing out of the toothed surface of the Lisu toothed belt or against molding defects. That is, according to the present invention, there is provided a method for manufacturing a toothed belt, which is characterized by forming a preform of a thermoplastic elastomer; The aforementioned protective fabric, rope and pre-formed article are placed in a molding mold. Qingyue. The above-mentioned composition is pressurized and heated; and a temperature higher than the crystallization temperature of the aforementioned thermoplastic elastomer and lower than the aforementioned melting point is used. The temperature is heated from the inside of the mold for a certain time to form the aforementioned teeth. In the manufacturing method of the aforementioned toothed belt, the aforementioned composition can be applied and heated from the outside, and higher than the aforementioned elastomer The crystallization temperature and the internal heating of it are low-determined_read_The flow / dish condition of the aforementioned hot ship complex can be maintained for a certain period of time for the formation of teeth ^ ie, because it can take a certain amount of time In the state in which the above-mentioned elastic bombardment system is controlled under the condition of the upper temperature, the aforementioned scales are made, so that the hot chick elastomer can be prevented from penetrating into the tooth surface of the toothed belt from the gap of the protective fabric. It also prevents molding defects and incomplete rounding of the teeth. 200404964 It should be noted that the aforementioned molding temperature range, that is, the aforementioned temperature range higher than the crystallization temperature of the aforementioned thermoplastic elastomer and lower than the aforementioned melting point is usually 125 ° C to 190QC. The aforementioned teeth can be formed by controlling the aforementioned molding temperature and heating for a certain period of time so that the flow rate of the aforementioned thermoplastic elastomer approaches 5 × 1 (T4 to 6x l (T3ml / sec (load is 50kgf / cm2, aperture X length is lmmxlmm). If the aforementioned molding temperature condition is set so that the flow rate of the thermoplastic elastomer is about 5x1 (between T4 and 6x10 ml / sec ', the temperature range is set so that the temperature is lower than the crystallization temperature of the thermoplastic elastomer and lower than The melting point can prevent the resin from seeping from the gap of the protective fabric to the tooth surface of the toothed belt and the molding defects of the toothed belt (the tips of the teeth cannot be completely formed and rounded), so the foregoing molding is more accurate. In order to measure the flow rate of the aforementioned thermoplastic elastomer, a flow tester CFT-500 manufactured by Shimadzu Mfg. Can be used. The test condition is a load of 50 kgfcm2, a warm-up time of 100 seconds, and a cross-sectional area of a cylindrical piston of 1 cm2. , The hole diameter x length of the die hole. In addition, after reaching the aforementioned set temperature (measurement temperature) and preheat for 100 seconds (maintain the same temperature for 100 seconds and make the temperature of the entire sample The same), a piston is used to provide a load of 50kgf / cm2 to the aforementioned sample, and the flow rate of the sample flowing out of the hole of the aforementioned die per unit time can be measured. The best is the ratio of the filament denier of the aforementioned protective fabric ( (Weft / warp) is 0.5 to 3Ό, the yarn density ratio (weft / warp) is 0.5 to ι · 〇, the elongation of the aforementioned protective fabric used for molding treatment is about 50% to 150% ( Under the condition of 50mm width / 2kgf). In addition, the aforementioned protective fabric is preferably treated with resin or moisture-curable polyurethane before molding. By using the aforementioned protective fabric constituted by this method, the aforementioned protective fabric is formed during the molding process. The flowing thermoplastic elastomer is extruded, and the filaments overlap even if stretched. Therefore, the openings of the voids can be reduced, the leakage of the voids of the resin lion protective fabric to the toothed surface can be prevented. It can prevent the above-mentioned molding impurities (the tip of the tooth can not be completely rounded). Because of 200404964, the foregoing molding is more accurate. In addition, by the resin treatment or the moisture-curable polyurethane treatment, the thermoplastic impurities and the The combination of the aforementioned _fabrics is more robust. According to this L, a manufacturing method of a toothed belt is provided, which is characterized in that: a protective fabric having elasticity is disposed on the surface of the teeth forming surface of the turning tool having a tooth shape, and The surface of the forehead _ thing near the mask and the aforementioned anti-interception object-inferior membrane, set the _ of the ambiguous resin film to be higher than that of the gambling and front face, and adopt a lower than The charm temperature is in the thermal knuckle body that forms the axis of the mask in a towel. Using this method of manufacturing a toothed belt, the table of the aforementioned protective fabric adjacent to the aforementioned molding mold is layered. 、 Fabric-stretched and have a ㉟ _ point higher than the aforementioned tape body material. Right Xiao ㈣ tape material is in a state of approximate motion at a low temperature of the resin of the tree and wears the gap of the anti-compliance fabric. :, It has a higher melting point and is not in a molten state at this time will prevent the aforementioned belt material from passing through. @ 此 ， The aforementioned belt material cannot penetrate the surface of Tusl, so it is not exposed on the surface side of the aforementioned belt teeth. : In addition, the protective fabric and tree can be squeezed and formed with the flowing belt material before forming the toothed belt until the difficulty with the Chengcheng mold, so the shaft has a protective fabric layer of substantially the same wealth and Resin Lai. If the protective fabric layer of the bottom liner has a uniform thickness', the pitch line becomes stable and the aforementioned rope can be secured, so the durability is improved.
