Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a bicycle rim. [Prior Art] Modern people's strong young Kang Lai 'Xu Yanren will Xiangxiang County bicycle trip' more because of the current oil price arrogance and the greenhouse effect is serious, so more and more people respond to the secret ring to use bicycles as (four) to work, Transportation to school. In view of the safety of this bicycle ride, more attention must be paid. In the bicycle components, the selection of a high-performance brake system not only enhances the sportiness, but also ensures safety. - The commonly used bicycle brake system can be divided into two types of clip brakes and disc brakes. The 'bringing brakes' are widely used because of their light weight and low unit price. Moreover, the clip brake is decelerated by friction between the brake pad and the brake side of the rim. In the long and steep continuous slope section, the clip and the brakes on the brake rim of the rim and the rim produce high temperature, causing the wheel to be injured or observed. It may even cause internal explosion or material loss. Therefore, in the field of general knowledge, in addition to improving the existing brake pads, how to provide a high temperature and wear resistant self-wheel rim is also an urgent problem to be overcome in the industry. SUMMARY OF THE INVENTION The object of the present invention is to solve the above problems and to provide a bicycle == the wheel_composite f is made and has: a corresponding brake side, the outer edge of the _ has a fluorine surface. Wherein, the second side of the vehicle is first blasted by 201132521 to remove the release agent on the side of the brake, and then is selected from the group consisting of polytetrafluoroethylene and fluorinated ethylene-propylene copolymer under the condition of a temperature of l〇〇t. a raw material of the group consisting of fluoroalkylate, ethylene-tetrafluoroethylene copolymer and a mixture thereof is sprayed on the side of the brake to make the material adhere to the side of the braker to a thickness of not less than 0.4 cm, and then gradually heat up The material is shaped on the side of the brake to form the fluoroplastic layer. The outer edge of the brake rim of the bicycle rim of the present invention has a gas-plastic layer, which can effectively reduce the high temperature caused by excessive friction, thereby increasing the stability of the bicycle grip brake system and improving the safety performance of the bicycle. [Embodiment] The present invention provides a bicycle that is resistant to high temperatures and stagnation. Please refer to FIG. 1 for a perspective view of the rim of the present invention. The bicycle rim 1 is made of a composite material such as carbon fiber, glass fiber or kewei fiber and has two corresponding Brake side 10 'The brake side 10 is used to friction with the clip brake, the W piece (not green) to achieve the effect of deceleration. Moreover, the outer edges of the two sides 10 have a fluoroplastic layer 2, respectively, please refer to the figure Μ, Fig. 3 and Fig. 3, Fig. 2 and Fig. 钟钟朗, and the 280 red material has gas _ 0 'And circle 3 is a sectional view of the rim of Figure 2. In this embodiment, the rim of the rim has a groove U, and the fluoroplastic layer is embedded in the groove 11. Ganzi. /, medium, due to the rim made of composite material, the surface has a layer of release agent, so the second teaching car side..., the early 10 series is first blasted to remove the brakes on the side of the car 5 201132521 The contactor is then treated with a grinding treatment to smooth the surface of the vehicle, and thereafter, under the condition of a temperature of HKTC, it is selected from the group consisting of polytetrafluoroethylene, vaporized ethylene, and secreted. Among the ethnic groups formed by the material, the material is sprayed on the side of the brake, and the thickness of the material adhered to the side of the brake car 1G is preferably 0.5 to 0.6 cm at a thickness of 0.5 cm. In order to achieve the above thickness, preferably The system adopts multiple spraying methods to achieve, for example, mining-secondary or secondary spraying, and each time between spraying and standing for one time, the city raw materials and the wheel (4) are pre-heated to give c, in order to facilitate the adhesion of raw materials. Lifting the spraying effect on the 1G side of the car; thereafter, gradually heating up to at least 180 °c to shape the material on the side of the brake 1G to form the fluoroplastic layer 2; more specifically, the attachment The rim is in the heating device, first set to stand at 100 〇c for 3G minutes, then warm to 1 thief and let stand for 1G minutes, then warm to 12〇 °C and let stand for 35 / min' after heating To 14 (rc and let stand for 4 minutes, then warm to 160 ° C and let stand for 30 minutes) and finally warm to 18 〇. 〇 and let stand for 6 〇 minutes to form the fluoroplastic layer 20. It should be noted that If the rim rapidly heats up to 180 ° C instead of gradually heating the segment, it will cause bubbles in the fluoroplastic layer 20 to affect its structural strength and The appearance 'is easy to peel off from the side of the brake. In the present embodiment, the fluoroplastic layer 20 is embedded in the groove 11 of the brake side 1 'of the ordinary knowledge in the field can also be as shown in FIG. 4 The brake side is designed to be in a stepped shape, so that the fluoroplastic layer 20 is applied to the entire outer edge of the brake side. Alternatively, the brake side 10 may not be formed with a groove or stepped 201132521 structure, and the fluorine is used. The plastic layer 20 is directly coated on the surface thereof. After forming the fluoroplastic layer, the outer surface of the rim is composed of a fluorine-containing plastic layer region and a fluorine-free plastic layer region, wherein the fluorine-free plastic layer region and the surface are formed. Treatment, such as soil filling, polishing, lacquering, etc., makes the rim meet the market demand. It should be noted that 'if the surface treatment such as sloping soil before riding, the paint will be heated. Deterioration, liquefaction, etc. In the present invention, the material of the material layer is composed of polytetraethylene acetamate, propylene propylene copolymer, ethylene _tetrafluoroethylene copolymer and mixtures thereof. The responsibility of the ethnic group - the above fluoroplastics It has excellent heat resistance and low friction' and is suitable for coating on the side of the wheel. Further, the fluoroplastic layer of the present invention may be blended with titanium metal to enhance its strength and (5) high temperature performance. In the layer of the brake side, it is preferred to use polytetrafluoroethylene as its material. Polytetrafluoroethylene is a kind of artificial wire molecule (four) which replaces all hydrogen atoms in the polyethylene with fluorine, due to the fine gas (4) The carbon bond is covered by the child, and due to the high stability of the fluorine-carbon bond, an inert fluorine-containing outer shell is formed outside the polytetrafluoroethylene molecule, which has a low impurity and is resistant to abrasion. Further, the inventors of the present invention separately perform braking tests on the rims of the uncoated plastic layer and the rims coated with the fluoroplastic layer. Among them, under the same environmental conditions, each set of rims is in the testing machine. The bench was braked three thousand times, and then the surface temperature of the brake side was measured. The test unit was. c.戦The results are shown in the table: 7 201132521 <Table 1>
