[0003] MC nylon sliders are mainly made by casting. Usually, in the production process of MC nylon sliders, the raw materials need to be dried and crushed, and then the raw materials of MC nylon are polymerized. After a certain period of polymerization, the nylon monomers gradually polymerize into high molecular chains to form MC nylon polymers with specific molecular weight and structure. The polymerized MC nylon is pelletized and dried, and the MC nylon particles are heated and melted, injected into the mold, cooled and solidified to form the required shape and size.

[0004] When high-performance MC nylon sliders are in the polymerization process, too high or too low temperature can easily lead to abnormal reaction rate and uneven product molecular weight distribution, and temperature fluctuations can easily lead to degradation of raw material performance.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] like Figure 1 and Figure 2As shown, a high-performance MC nylon slider according to an embodiment of the present invention comprises a slider body 1, a plurality of through holes 10 are provided in the middle of the slider body 1, two mounting grooves 11 are provided on the side wall of the slider body 1, a buffer plate 15 is installed in the middle of the mounting groove 11, two groups of fixing grooves 12 are provided in the middle of the slider body 1, the two groups of fixing grooves 12 are arranged oppositely, the fixing grooves 12 are arranged on one side of the corresponding mounting groove 11, a spring 13 is fixedly connected in the middle of the fixing groove 12, a buffer pad 14 is fixedly connected to the end of the spring 13, when working, the two buffer plates 15 are respectively inserted into the slider body 1 from one end of the mounting groove 11, the spring 13 is in a naturally extended state, when the buffer plate 15 is inserted, it fits with the buffer pad 14, and at the same time, the spring 13 generates elastic contraction, and the buffer pad 14 fits tightly in the middle of the buffer plate 15, when the slider body 1 is installed and used, When the slider body 1 is subjected to external impact force, the impact force is first transmitted to the buffer plate 15. The buffer plate 15 will compress the buffer pad 14 and the spring 13 downward when impacted. The spring 13 undergoes elastic deformation and stores part of the impact energy, further absorbing and dispersing the vibration and impact load. As the impact force gradually weakens, the spring 13 recovers the deformation and releases the stored energy, helping the slider body 1 to reset smoothly. This step can effectively reduce the impact force and vibration amplitude of the slider body 1 under continuous or repeated impacts through the coordinated use of the spring 13, the buffer pad 14 and the buffer plate 15, thereby protecting the slider body 1 and the mechanical structure made of it from damage. The dual effects of the spring 13 and the buffer plate 15 improve the shock-absorbing and buffering performance of the slider body 1, effectively reducing the wear and fatigue damage caused by vibration and impact, thereby extending the service life of the slider body 1 and related mechanical components.

[0036] like Figure 3 As shown, a high-performance MC nylon slider is characterized in that the specific processing steps of a high-performance MC nylon slider preparation method are as follows:

[0037] S1: Use a high-precision platform scale to accurately measure the weight of the amount used, put 100 parts of caprolactam base raw material, 6-10 parts of glass fiber reinforcement, 4-8 parts of nano calcium carbonate filler, 5-15 parts of fly ash filler, 0.5-1.6 parts of sodium hydroxide catalyst, and 0.1-1 part of toluene diisocyanate activator into the polymerization device according to the process requirements, and mix the raw materials evenly according to the proportion through a stirring device.

[0038] S2: Melt it under heating conditions, and polymerize the raw materials under the action of catalysts and activators. The monomer molecules are connected by covalent bonds or other types of chemical bonds to form polymer compounds. The reaction temperature of the raw materials is then controlled by heating or cooling.

[0039] S3: The MC nylon polymer after polymerization reaction is cut into small particles by a pelletizer and quickly cooled to room temperature. The pelletized MC nylon particles are then placed in a dryer for drying to remove the residual moisture and volatile substances in the MC nylon particles.

[0040] S4: The dried MC nylon pellets are heated to a molten state, injected into a mold by an injection molding machine to form a slider, and then the molded MC nylon slider is annealed, cooled, demolded, cut, and quality inspected and tested for performance.

[0041] like Figures 4 to 7 As shown, the preparation equipment is applicable to any one of the high-performance MC nylon slider preparation methods in claim 2, including a reactor 2, characterized in that: a mixing barrel 20 is fixedly connected to the top of the slider body 1, the mixing barrel 20 is fixedly connected to the inside of the reactor 2, a control room 21 is arranged between the mixing barrel 20 and the reactor 2, a water inlet pipe 22 is fixedly connected to the side wall of the reactor 2, a water outlet pipe 23 is fixedly connected to the side wall of the reactor 2, the ends of the water inlet pipe 22 and the water outlet pipe 23 pass through the middle of the reactor 2, and the middle of the water outlet pipe 23 is installed There is a one-way valve 24, a heat-conducting pipe 25 is fixedly connected in the middle of the mixing barrel 20, and the heat-conducting pipe 25 is arranged inside the temperature-controlled chamber 21. A heat-conducting plate 26 is fixedly connected in the middle of the mixing barrel 20, and the heat-conducting plate 26 is fixedly connected to the outside of the heat-conducting pipe 25. A discharge pipe 27 is fixedly connected between the mixing barrel 20 and the bottom of the reactor 2. A stirring component 3 is installed in the middle of the reactor 2. When working, raw materials, fillers, enhancers, catalysts, and activators are placed in the mixing barrel 20 according to the specified ratio, and the raw materials are stirred and mixed by the stirring component 3. At the same time, the end of the water inlet pipe 22 is connected to the hot water pipe, and the hot water is discharged into the control chamber 21 through the water inlet pipe 22. The heat in the hot water is transferred to the raw materials in the mixing barrel 20 through the heat conducting plate 26 and the heat conducting pipe 25, thereby providing the heat energy required by the raw materials in the reaction process inside the mixing barrel 20. When the reaction temperature inside the mixing barrel 20 is high, the end of the water inlet pipe 22 is connected to the cold water pipe, and the cold water is discharged into the control chamber 21, thereby removing the high heat generated during the reaction of the raw materials and achieving temperature control of the raw material reaction. When the cold water or hot water needs to be discharged, the one-way valve 24 is opened and discharged through the outlet pipe 23. This step can accurately control the temperature inside the reactor 2 by circulating hot water or cold water, can effectively maintain a constant temperature of the raw material polymerization reaction, and effectively reduce the problem of raw material performance degradation due to temperature fluctuations. The heat conducting pipe 25 and the heat conducting plate 26 can effectively transfer heat to the inside of the mixing barrel 20, thereby achieving uniform heat distribution, effectively reducing the occurrence of local overheating or overcooling, and maintaining the uniformity of the overall temperature of the raw materials.

[0042] like Figures 4 to 7As shown, the stirring assembly 3 includes an electric push rod 31, the middle part of the electric push rod 31 passes through the top of the reactor 2, the output end of the electric push rod 31 is hollow, the output end of the electric push rod 31 is fixedly connected to a rotating seat 32, the middle part of the electric push rod 31 is rotatably connected, the bottom of the mixing barrel 20 is fixedly connected to a support seat 36, the support seat 36 is fixedly connected to the inside of the mixing barrel 20, the middle part of the support seat 36 is fixedly connected to a screw 35, the screw 35 is arranged in the electric push rod 31, the sleeve 33 is threadedly connected to the middle part of the screw 35, the end of the sleeve 33 is fixedly connected to a rubber pad 34, the middle part of the sleeve 33 is fixedly connected to two stirring blades 37, the two stirring blades 37 are arranged oppositely, when the electric push rod 31 is powered on and turned on, the output end of the electric push rod 31 drives the sleeve 33 to move downward, the screw 35 is arranged in the electric push rod 31 and moves, when the sleeve 33 moves to the middle of the screw 35 When moving downward, it rotates through threaded engagement, and at the same time, the sleeve 33 rotates in the middle of the rotating seat 32. When the sleeve 33 moves up and down and rotates, the raw materials are evenly mixed and stirred by two stirring blades 37. When the sleeve 33 moves to the bottom close to the support seat 36, the sleeve 33 is brought into contact with the support seat 36 through the rubber pad 34, and the electric push rod 31 is controlled to move upward again. The stirring blades 37 move up and down and rotate to stir the raw materials so that they are quickly and evenly polymerized. This step is achieved by moving the stirring blades 37 up and down and rotating at the same time, which can effectively make the raw materials in the mixing barrel 20 be fully and evenly mixed, effectively reduce the local concentration differences in the raw materials, effectively improve the uniformity of the raw material polymerization reaction, and effectively reduce the problem of some raw materials not being fully mixed due to stirring dead corners. In addition, the flow of raw materials can enhance the heat transfer effect, so that heat can be transferred and distributed faster in the raw materials, thereby maintaining the uniformity of the raw material reaction temperature.

[0043] like Figures 4 to 6As shown, a vacuum groove 4 is provided on the top of the reactor 2, and the vacuum groove 4 is arranged inside the reactor 2. An alarm 41 is installed on the top of the reactor 2, and a sensor head 42 is installed at the bottom of the alarm 41. The sensor head 42 penetrates the top of the reactor 2, and the sensor head 42 is arranged inside the vacuum groove 4. A piston plate 43 is slidably connected in the middle of the vacuum groove 4. During operation, when the pressure of the raw material reaction process is too high, the pressure pushes the piston plate 43 to move the piston plate 43 upward in the middle of the vacuum groove 4. When the piston plate 43 comes into contact with the sensor head 42, the sensor head 42 transmits a signal to the alarm 41, and an alarm signal is sent through the alarm 41, so that the staff can take corresponding safety measures. In this step, the pressure inside the mixing barrel 20 can be monitored in real time through the coordinated use of the piston plate 43 and the sensor head 42, which can reduce the problem of equipment damage caused by excessive pressure inside the mixing barrel 20, and can effectively reduce the damage to the container wall, seals and other components inside the mixing barrel 20 caused by excessive pressure. Timely alarm signals can enable operators to quickly understand the abnormal pressure and take corresponding measures in time.

[0044] like Figures 4 to 7 As shown, a placement groove 5 is provided on the top of the reactor 2, and a feed box 51 is rotatably connected to the middle of the placement groove 5. A first feed hole 52 is provided at the bottom of the feed box 51, and a plurality of second feed holes 53 are provided on the top of the reactor 2. The plurality of second feed holes 53 are arranged at positions corresponding to the feed box 51, and the plurality of second feed holes 53 are arranged from large to small. During operation, the feed box 51 is rotated inside the placement groove 5 to rotate the first feed hole 52 to a position corresponding to one of the second feed holes 53, and the catalyst is placed inside the feed box 51. The flow rate of the catalyst entering the mixing barrel 20 is controlled by overlapping the first feed hole 52 with the second feed holes 53 of different sizes. In this step, the catalyst addition flow rate can be controlled through the feed box 51, so that the polymerization reaction can be carried out at an appropriate speed, and uneven polymerization caused by too fast reaction or decreased production efficiency caused by too slow reaction can be reduced. The temperature and pressure conditions of the polymerization reaction can be stabilized, so that the reaction process can be carried out within a controllable range.

[0045] like Figures 5 to 8As shown, a hinge shaft 6 is fixedly connected to the middle of the mixing barrel 20, and a sealing plate 60 is rotatably connected to the middle of the hinge shaft 6. A fixed tube 61 is fixedly connected to the middle of the mixing barrel 20, and the fixed tube 61 passes through the heat conducting plate 26 and the middle of the reactor 2. A sampling tube 62 is installed in the middle of the fixed tube 61, and a sampling port 63 is opened in the middle of the sampling tube 62. A handle 64 is fixedly connected to the end of the sampling tube 62. During operation, when the raw materials are polymerized, the handle 64 is held to put the sampling tube 62 corresponding to one end of the fixed tube 61, and the sampling tube 62 is pushed to slide inside the fixed tube 61. During the pushing process, the end of the sampling tube 62 contacts the sealing plate 60, and the continuous pushing causes one end of the sampling tube 62 to apply pressure to the sealing plate 60. The hinged shaft 6 causes the sealing plate 60 to rotate, and one end of the sampling tube 62 enters the raw material inside the mixing barrel 20. The raw material enters the sampling tube 62 through the sampling port 63 for sampling. After sampling, the sampling tube 62 is pulled outward, and at the same time, the sealing plate 60 is rotated and reset by the torsion spring, and the middle part of the mixing barrel 20 is sealed through the sealing plate 60, thereby completing the sampling work for analysis. In this step, the raw material polymerization is quickly sampled through the sampling tube 62, which can reflect the current state of the polymerization reaction in real time, can effectively grasp the reaction progress, can promptly discover abnormal situations occurring during the polymerization reaction, can promptly take corresponding measures for adjustment, effectively reduce the production of unqualified products and the waste of raw materials, and effectively reduce production costs.

[0046] like Figures 4 to 7 As shown, a heat preservation cover 7 is fixedly connected to the middle of the reactor 2, and the end of the fixed pipe 61 passes through the middle of the heat preservation cover 7. During operation, when the raw materials undergo polymerization reaction, the heat exchange between the surface of the reactor 2 and the air is isolated by the heat preservation cover 7, so that the inside of the reactor 2 is insulated. This step can effectively reduce the heat exchange between the reactor 2 and the external environment through the heat preservation cover 7, effectively reduce the heat loss inside the reactor 2, thereby reducing energy consumption, and can provide a relatively stable temperature environment, reduce the influence of the external environment on the internal temperature of the reactor 2, and effectively maintain the uniformity and consistency of the polymerization reaction, thereby improving the quality and stability of the product.

[0047] like Figures 4 to 7 As shown, a protective cover 8 is installed on the top of the feed box 51, and the middle part of the protective cover 8 is threadedly connected to the top of the feed box 51. During operation, after the catalyst is placed, the protective cover 8 is placed against the end of the feed box 51, and the protective cover 8 is rotated to seal the end of the feed box 51. This step can effectively isolate dust and impurities from the external environment from entering the feed box 51 through the protective cover 8, effectively reduce the contamination of the catalyst during the placement process, and effectively maintain the purity and activity of the catalyst.

[0048] During operation, the two buffer plates 15 are respectively inserted into the interior of the slider body 1 from one end of the mounting groove 11, and the spring 13 is in a naturally extended state. When the buffer plate 15 is inserted, it fits with the buffer pad 14, and the spring 13 elastically contracts. The buffer pad 14 fits tightly in the middle of the buffer plate 15. After the slider body 1 is installed and used, when the slider body 1 is subjected to external impact force, the impact force is first transmitted to the buffer plate 15. The buffer plate 15 will compress the buffer pad 14 and the spring 13 downward when impacted. The spring 13 undergoes elastic deformation and stores part of the impact energy, further absorbing and dispersing vibration and impact loads. As the impact force gradually weakens, the spring 13 recovers its deformation and releases the stored energy, helping the slider body 1 to smoothly reset.

[0049] The raw materials, fillers, enhancers, catalysts, and activators are placed in the mixing barrel 20 according to the specified ratio, and the raw materials are stirred and mixed by the stirring assembly 3. At the same time, the end of the water inlet pipe 22 is connected to the hot water pipe, and the hot water is discharged to the inside of the control chamber 21 through the water inlet pipe 22. The heat in the hot water is transferred to the raw materials in the mixing barrel 20 through the heat conduction plate 26 and the heat conduction pipe 25, thereby providing the heat energy required for the raw materials in the reaction process inside the mixing barrel 20. When the reaction temperature inside the mixing barrel 20 is high, the end of the water inlet pipe 22 is connected to the cold water pipe, and the cold water is discharged to the inside of the control chamber 21, thereby removing the higher heat generated during the raw material reaction process and realizing temperature control of the raw material reaction. When cold water or hot water needs to be discharged, the one-way valve 24 is opened and discharged through the outlet pipe 23.

[0050] When the pressure of the raw material reaction process is too high, the pressure pushes the piston plate 43, causing the piston plate 43 to move upward in the middle of the vacuum tank 4. When the piston plate 43 comes into contact with the sensor head 42, the sensor head 42 transmits a signal to the alarm 41, which sends an alarm signal to enable the staff to take corresponding safety measures.

[0051] The feed box 51 is rotated inside the placement groove 5 to rotate the first feed hole 52 to a position corresponding to one of the second feed holes 53, and the catalyst is placed inside the feed box 51. The flow rate of the catalyst entering the mixing barrel 20 is controlled by overlapping the first feed hole 52 with the second feed holes 53 of different sizes.

[0052] When the raw materials are in the polymerization reaction process, the heat exchange between the surface of the reactor 2 and the air is isolated by the heat-insulating cover 7, so that the inside of the reactor 2 is kept warm.

[0053] After the catalyst is placed, the protective cover 8 is aligned with the end of the feed box 51 , and the protective cover 8 is rotated to seal and protect the end of the feed box 51 .
