Description

Technical Field

[0001] This invention relates to the field of materials preparation technology, and in particular to equipment and processes for preparing high-flowability polyphenylene ether-specific high-temperature resistant lubricating materials. Background Technology

[0002] With the continuous growth of modern industry's demand for high-performance polymer materials, polyphenylene oxide (PPO) has been widely used in the electronics, electrical, and automotive industries due to its excellent heat resistance, mechanical strength, and dimensional stability. In the preparation of high-flow polyphenylene oxide special high-temperature resistant lubricating materials, it is first necessary to accurately proportion and pretreat the polyphenylene oxide resin matrix with components such as high-temperature resistant fillers and lubricating agents. Then, it is dispersed and homogenized through a special mixing equipment. Finally, a special mixed material with stable lubrication performance and excellent processing flowability is obtained. It is then processed into the final product through subsequent processes such as extrusion granulation and compression molding.

[0003] Currently, the preparation of this material mainly relies on mechanical stirring equipment, which mixes materials through rotational stirring. However, in existing technologies, the stirring method used by traditional stirring equipment is usually a single fixed-shaft rotation mode. This fixed stirring structure easily leads to the formation of a stable laminar flow field inside the material during operation. This flow field mode is difficult to provide sufficient shear force to break up the filler agglomerates, which in turn easily leads to the agglomeration tendency of nano-sized fillers in the matrix, forming secondary agglomerates that are difficult to disperse. This agglomeration phenomenon easily leads to a decrease in the uniformity of filler distribution in the matrix, affecting the mechanical properties and lubrication stability of the material after formation. At the same time, in the actual production process, due to the lack of an effective flow field control mechanism, some materials are easily deposited at the bottom of the preparation tank due to gravity, forming a mixing dead zone, resulting in uneven component distribution. This can lead to performance differences in different batches of the finished product, or even in different parts of the same batch, affecting the product consistency and reliability of the material. Summary of the Invention

[0004] The purpose of this invention is to provide equipment and process for preparing high-flowability polyphenylene ether-specific high-temperature resistant lubricating materials, so as to solve the problems mentioned in the background art, such as the instability of laminar flow field, insufficient shear force, and the formation of a mixing dead zone at the bottom of the tank caused by the single rotation mode of traditional stirring equipment.

[0005] The equipment and process for preparing high-flowability polyphenylene ether-specific high-temperature resistant lubricating materials provided by this invention adopt the following technical solution: Equipment for preparing high-flowability polyphenylene ether-specific high-temperature resistant lubricating materials, including: The preparation tank, a motor mounted on the preparation tank, a main shaft located inside the preparation tank, and multiple stirring blades mounted on the main shaft, wherein the main shaft is connected to the output end of the drive motor, and further includes: A flow-dispersing assembly is disposed inside the preparation tank. The flow-dispersing assembly includes a fixed shaft fixedly connected to the inner wall of the preparation tank, a sleeve shaft rotatably sleeved on the fixed shaft, multiple frames fixedly connected to the sleeve shaft, and multiple flow-circling rods disposed on each frame. The flow-circling rods and stirring blades are arranged alternately, and the stirring blades can pass through the gaps between adjacent flow-circling rods. A torsion spring is sleeved on the fixed shaft, and the two ends of the torsion spring are fixedly connected to the fixed shaft and the sleeve shaft, respectively. A drive unit is mounted on the main shaft. The drive unit includes a slot at the bottom of the main shaft, a sliding member slidably disposed in the slot, and two sets of clamping arms rotatably connected to the main shaft. The bottom end of the clamping arm is provided with a clamping port for clamping the sleeve shaft to control the frame and the flow rod to rotate with the main shaft, and to reverse the frame and the flow rod after releasing the sleeve shaft.

[0006] Furthermore, the clamping arm is rotatably connected to the main shaft via a rotating shaft, the upper end of the clamping arm is provided with an incomplete gear, the sliding member is provided with a rack plate that meshes with the incomplete gear, a spring is provided between the sliding member and the slot, and a rope is connected to the sliding member.

[0007] Furthermore, the drive unit also includes a movable cavity opened in the main shaft, a reel rotatably connected in the movable cavity, one end of the rope being fixed to the reel and wound around its surface, and a slot for the rope to pass through is opened in the main shaft.

[0008] Furthermore, the drive unit also includes an annular sleeve fixed inside the preparation tank, the annular sleeve having an arc-shaped rack, one end of the scroll extending outside the main shaft and fixed with a driven gear, the driven gear meshing with the arc-shaped rack.

[0009] Furthermore, the bottom of the annular sleeve is fixedly connected to two sets of arc-shaped guide plates, which are fixed together by a connecting frame to form a track for the roller to enter. The part of the roller entering the track is provided with a convex pad.

[0010] Furthermore, it also includes a jet assembly, which includes an annular gas sleeve fixed inside the preparation tank, a gas chamber opened inside the annular gas sleeve, and an air inlet pipe connected to the annular gas sleeve. The air inlet pipe extends to the outside of the preparation tank and is connected to an external air source. The main shaft has an axial channel, and the main shaft has an air hole communicating with the gas chamber. The main shaft rotates through the center of the annular gas sleeve. The sliding member has a vertical shaft at the top and a nozzle at the bottom. A continuous airflow channel is formed through the vertical shaft, the sliding member, and the nozzle. The nozzle has multiple sets of spray holes along its circumference.

[0011] Furthermore, an elastic sleeve is fixedly fitted on the outer side of the sleeve shaft, and the clamping port of the clamping arm contacts the elastic sleeve.

[0012] Furthermore, the bottom end of the spindle is provided with a clearance opening for the clamping arm to swing, and a flexible pad is provided on the clearance opening, with the two ends of the flexible pad connected to the edge of the clearance opening and the clamping arm, respectively.

[0013] Furthermore, a temperature sensor is installed inside the preparation vessel, and a controller is installed outside the preparation vessel. The temperature sensor and the controller are electrically connected.

[0014] The preparation process of a high-flowability polyphenylene ether (PPE)-specific high-temperature resistant lubricating material, using the aforementioned equipment for preparing such a material, includes the following steps: Step 1: Add the measured polyphenylene ether resin matrix, heat-resistant reinforcing filler, lubricant and other functional additives into the preparation tank, and start the motor to drive the main shaft and stirring blades to perform preliminary mixing of the materials; Step 2: The rotation of the main shaft triggers the working cycle of the drive unit. The clamping arm holds the sleeve shaft, causing the turbulence component and the stirring blade to rotate synchronously, thus performing high-intensity shearing and dispersion on the material. Step 3: When the drive unit reaches the release stage, the clamping arm swings outward and opens, releasing the sleeve shaft, causing the turbulence component to rotate in the opposite direction at high speed under the drive of the torsion spring, generating violent turbulence; Step 4: The opening clamping arms can cut into and scoop up the material deposited at the bottom of the preparation tank, turn it upwards, and agitate the material; Step 5: During the mixing process, when the temperature of the preparation tank is too high, cooling gas is passed through the jet assembly and evenly injected into the material from the nozzle orifice to achieve temperature control. Step Six: Once the materials have reached the predetermined mixing degree, stop the equipment and discharge the prepared materials from the preparation tank for subsequent processing.

[0015] The beneficial effects of this invention are: By setting up a turbulence-inducing component and a drive unit, when the main shaft rotates to a specific position, the driven gear in the drive unit meshes with the arc-shaped rack, which can automatically trigger the clamping arm to clamp the shaft, so that the turbulence-inducing component and the stirring blade rotate synchronously in the forward direction, and perform strong shearing on the material. When disengaged, it can automatically switch to the release mode, and the turbulence-inducing component rapidly reverses under the action of the torsion spring, generating violent reverse turbulence. By utilizing the periodic switching between forward and reverse rotation, the steady flow field formed by traditional stirring equipment is effectively broken, and the laminar boundary layer of the material is broken, thereby improving the dispersion efficiency and mixing uniformity between materials.

[0016] By setting up the jet assembly, when the temperature sensor detects that the material temperature exceeds the set threshold, the external air source can be activated to uniformly inject cooling gas into the material through the nozzle. Through direct jet cooling, the frictional heat and reaction heat generated during the mixing process can be removed in time, effectively preventing the decomposition and denaturation of heat-sensitive materials such as polyphenylene ether due to local overheating. At the same time, the injected airflow can also help enhance the turbulence of the material, further improving the mixing quality. Attached Figure Description

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Example 1, refer to Figures 1-2 The present invention provides a preparation equipment for high-flow polyphenylene ether special high-temperature resistant lubricating material, including a preparation tank 100, a motor 200 disposed on the preparation tank 100, a main shaft 300 disposed inside the preparation tank 100, and a plurality of stirring blades 400 disposed on the main shaft 300, wherein the main shaft 300 is connected to the output end of the drive motor 200.

[0021] Reference Figures 2-4 It also includes a turbulence assembly 500, which is disposed inside the preparation tank 100. Specifically, the turbulence assembly 500 includes a fixed shaft 501 fixedly connected to the inner wall of the preparation tank 100, a sleeve shaft 502 rotatably sleeved on the fixed shaft 501 via a bearing, a plurality of frames 503 fixedly connected to the sleeve shaft 502, and a plurality of flow-around rods 504 disposed on each frame 503. The flow-around rods 504 are staggered with the stirring blades 400, and the stirring blades 400 can pass through the gaps between adjacent flow-around rods 504. A torsion spring 505 is sleeved on the fixed shaft 501. The two ends of the torsion spring 505 are fixedly connected to the fixed shaft 501 and the sleeve shaft 502 respectively. When the sleeve shaft 502 is driven to rotate, the torsion spring 505 can undergo torsional deformation to store elastic potential energy.

[0022] When the sleeve shaft 502 is driven to rotate, it can drive the entire frame 503 and the flow rod 504 to rotate synchronously. When the driving force of the sleeve shaft 502 is removed, the elastic potential energy stored in the torsion spring 505 will be released, driving the sleeve shaft 502 together with the frame 503 and the flow rod 504 to rotate in the opposite direction, thereby causing a reverse disturbance to the material in the preparation tank 100.

[0023] Reference Figures 2-3 and Figures 5-6 The main shaft 300 is equipped with a drive unit 600. Specifically, the drive unit 600 includes a slot 601 opened at the bottom end of the main shaft 300, a sliding member 602 slidably disposed in the slot 601, and two sets of clamping arms 603 rotatably connected to the main shaft 300. The bottom end of the clamping arm 603 is provided with a clamping port for clamping the sleeve shaft 502 to control the frame 503 and the flow rod 504 to rotate with the main shaft 300, and after releasing the sleeve shaft 502, the frame 503 and the flow rod 504 reverse to achieve dynamic turbulence.

[0024] Reference Figure 4 The sleeve shaft 502 is externally fixed with an elastic sleeve 506, which can be made of rubber. The clamping port of the clamping arm 603 contacts the elastic sleeve 506. The elastic deformation of the elastic sleeve 506 can increase the friction between the clamping arm 603 and the sleeve shaft 502, ensuring a firm clamping and preventing slippage.

[0025] It should be noted that when the two sets of clamping arms 603 approach and clamp the sleeve shaft 502 through the clamping port, the rotational motion of the main shaft 300 is transmitted to the turbulence assembly 500. When the two sets of clamping arms 603 open and release the sleeve shaft 502, the turbulence assembly 500 moves independently in the opposite direction under the action of the torsion spring 505.

[0026] Reference Figures 5-6 The clamping arm 603 is rotatably connected to the main shaft 300 via a rotating shaft 604. The upper end of the clamping arm 603 is provided with an incomplete gear 605. The sliding member 602 is provided with a rack plate 606 that meshes with the incomplete gear 605. A spring 607 is provided between the sliding member 602 and the slot 601. The two ends of the spring 607 are respectively fixedly connected to the slot 601 and the sliding member 602. The spring 607 is usually in an extended state, which makes the sliding member 602 tend to move downward. In addition, a rope 608 is connected to the sliding member 602 to provide upward tension.

[0027] Specifically, the drive unit 600 also includes a movable cavity 609 opened in the main shaft 300. A reel 610 is rotatably connected in the movable cavity 609 via a bearing. One end of the rope 608 is fixed to the reel 610 and wound around its surface. The main shaft 300 has a slot 611 for the rope 608 to pass through, so that the rope 608 passes through the movable cavity 609 into the slot 601 and is fixedly connected to the sliding member 602. By controlling the rotation of the reel 610 to tighten or loosen the rope 608, the sliding member 602 moves in the slot 601 to drive the clamping arm 603 to swing.

[0028] Reference Figures 7-8 The drive unit 600 also includes an annular sleeve block 612 fixed inside the preparation tank 100. The annular sleeve block 612 is located outside the main shaft 300. An arc-shaped rack 613 is provided on the annular sleeve block 612. One end of the reel 610 extends outside the main shaft 300 and is fixed with a driven gear 614. When the main shaft 300 rotates to a specific position, when the driven gear 614 on the reel 610 enters the arc-shaped rack 613 section on the annular sleeve block 612, the reel 610 rotates and tightens the rope 608, causing the clamping arm 603 to swing inward and clamp the sleeve 502. At this time, the rotational power of the main shaft 300 can be directly transmitted to the turbulence assembly 500, so that it rotates synchronously with the stirring blade 400 to strongly mix the material.

[0029] Two sets of arc-shaped guide plates 615 are fixedly connected to the bottom of the annular sleeve block 612. The two sets of arc-shaped guide plates 615 are fixed together by a connecting frame 616, forming a track 617 for the reel 610 to enter. The part of the reel 610 entering the track 617 is provided with a convex pad 618, which can be made of rubber. When the driven gear 614 disengages from the arc-shaped rack 613, the reel 610 immediately enters the section of track 617 formed by the arc-shaped guide plates 615. At this time, the friction generated between the convex pad 618 and the inner wall of the track 617 causes the reel 610 to revolve with the main shaft 300, but it cannot rotate on its own. During this stage, the clamping arm 603 continues to clamp, and the turbulence component 500 continues to rotate synchronously with the main shaft 300.

[0030] After the reel 610 leaves the track 617, it enters a free section without any external constraints. At this time, under the elastic action of the spring 607, the sliding member 602 is pulled down, causing the reel 610 to rotate and unwind the rope 608. This drives the clamping arm 603 to swing outward and open the release sleeve 502. The torsion spring 505, which was previously tightened during the synchronous rotation phase, immediately releases its stored elastic potential energy, driving the sleeve 502, frame 503, and flow rod 504 to rotate in the opposite direction, achieving a violent reverse turbulence.

[0031] It should be noted that, referring to Figure 9The bottom end of the main shaft 300 is provided with a clearance opening 619 for the clamping arm 603 to swing. The clearance opening 619 is connected to the slot 601. A flexible gasket 620 is provided on the clearance opening 619. The two ends of the flexible gasket 620 are respectively connected to the edge of the clearance opening 619 and the clamping arm 603. The flexible gasket 620 can effectively seal the clearance opening 619 while ensuring that the clamping arm 603 swings flexibly. When the clamping arm 603 swings, it can drive the flexible gasket 620 connected to it to undergo stretching or compression deformation, thereby preventing material from entering the interior of the main shaft 300.

[0032] By controlling the turbulence component 500 to periodically switch between synchronous forward rotation and driven reverse rotation, the sudden change in its direction of motion can break the laminar boundary layer formed inside the material, thereby effectively improving the dispersion efficiency and mixing uniformity between materials. It should be noted that when the clamping arm 603 swings outward and opens, the arm of the clamping arm 603 can cut into and scoop up the material deposited below the preparation tank 100, turn it upward and stir the material. Through the stirring action, the problem of sedimentation and mixing dead zone that easily occurs at the bottom of the preparation tank 100 can be effectively solved, and the uniformity of material mixing in the entire preparation tank 100 can be further improved.

[0033] Furthermore, refer to Figures 10-11 It also includes a jet assembly 700. Specifically, the jet assembly 700 includes an annular gas sleeve 701 fixed inside the preparation tank 100, a gas chamber 702 opened inside the annular gas sleeve 701, and an air inlet pipe 703 connected to the annular gas sleeve 701. The air inlet pipe 703 extends to the outside of the preparation tank 100 and is connected to an external air source. A channel 704 is axially opened inside the main shaft 300, and an air hole 705 communicating with the gas chamber 702 is opened on the main shaft 300. The main shaft 300 is rotatably inserted through the center of the annular gas sleeve 701 via a sealed bearing. Regardless of the main shaft 300 Regardless of rotation, the air chamber 702 can remain connected to the channel 704 through the air hole 705, realizing gas transmission under dynamic sealing. The top of the sliding member 602 is provided with a vertical shaft 706 and the bottom is provided with a nozzle 707. A continuous airflow channel 708 is opened through the vertical shaft 706, the sliding member 602 and the nozzle 707. The vertical shaft 706 is slidably disposed in the channel 704. The upper end of the airflow channel 708 is connected to the channel 704. Multiple sets of nozzle holes 709 are opened along the circumference of the nozzle 707. The nozzle holes 709 are used to inject gas into the material.

[0034] When the gas enters the rotating main shaft 300 from the stationary annular gas sleeve 701 through the gas hole 705, it will flow downward along the channel 704 of the main shaft 300. The gas will then enter the airflow channel 708 inside the sliding member 602 and the nozzle 707 through the vertical shaft 706, and finally be ejected at high speed from the multiple nozzle holes 709 around the nozzle 707, directly into the material area.

[0035] Reference Figures 1-2 A temperature sensor 800 is installed inside the preparation tank 100. The temperature sensor 800 can be, but is not limited to, a platinum resistance temperature sensor (such as PT100). A controller 900 is installed outside the preparation tank 100. The temperature sensor 800 and the controller 900 are electrically connected. During the stirring and mixing process, the material will generate heat due to shear friction and chemical reaction. When the temperature sensor 800 detects that the temperature inside the preparation tank 100 exceeds the preset safety threshold, it will immediately transmit the signal to the controller 900. The controller 900 then issues a command to start the external air source. The external air source can be an air pump supplying air to introduce cooling gas into the jet assembly 700 and finally spray it out from the nozzle 707, directly contacting the high-temperature material for heat exchange, thereby achieving rapid and precise active cooling and effectively preventing the material from decomposing or denaturing due to overheating.

[0036] The working principle of the high-flowability polyphenylene ether (PPE) special high-temperature resistant lubricating material preparation equipment provided by this invention is as follows: First, the main shaft 300 and stirring blade 400 are driven to rotate by the motor 200 to stir the material in the preparation tank 100. When the main shaft 300 rotates to a specific position, the driven gear 614 on the reel 610 meshes with the arc-shaped rack 613 fixed on the annular sleeve block 612, driving the reel 610 to rotate, tightening the rope 608. The rope 608 pulls the sliding member 602 upward, and through the transmission of the rack plate 606 and the incomplete gear 605, drives the two sets of clamping arms 603 to swing inward, so that its bottom... The clamping port of the part firmly clamps the elastic sleeve 506 outside the sleeve shaft 502 on the fixed shaft 501. At this time, the frame 503 and the flow rod 504 rotate synchronously with the stirring blade 400 to perform strong shearing and mixing of the material. When the driven gear 614 disengages from the arc rack 613, the reel 610 immediately enters the track 617 section formed by the arc guide plate 615. The friction between the convex pad 618 and the inner wall of the track 617 stops the reel 610 from rotating. The rope 608 remains taut, the clamping arm 603 maintains the clamping state, and the turbulence component 500 continues to rotate synchronously to ensure the continuous stability of the mixing process.

[0037] Subsequently, when the spool 610 leaves the track 617 and enters the free section, under the restoring force of the spring 607, the sliding member 602 moves downward, causing the spool 610 to reverse and unwind. The rope 608 loosens, and the clamping arm 603 swings outward to release the sleeve 502. At this time, the released turbulence component 500 rotates rapidly in the opposite direction under the drive of the potential energy stored in the torsion spring 505, causing reverse turbulence.

[0038] If the temperature inside the preparation tank 100 exceeds the preset threshold, the controller 900 will activate the external gas source. The cooling gas enters the gas chamber 702 through the air inlet pipe 703, enters the channel 704 through the air hole 705, and is finally ejected from the nozzle 709 through the air flow channel 708 to achieve active cooling.

[0039] Example 2: This invention also provides a preparation process for a high-flowability polyphenylene ether (PPE)-specific high-temperature resistant lubricating material, using equipment for preparing such materials, including the following steps: Step 1: Add the measured polyphenylene ether resin matrix, heat-resistant reinforcing filler, lubricant and other functional additives into the preparation tank 100, and start the motor 200 to drive the main shaft 300 and stirring blades 400 to perform preliminary mixing of the materials. Step 2: The working cycle of the rotation trigger drive unit 600 of the main shaft 300, through the clamping arm 603 clamping the sleeve shaft 502, makes the turbulence component 500 and the stirring blade 400 rotate synchronously in the forward direction, and implement high-intensity shearing and dispersion of the material; Step 3: When the drive unit 600 reaches the release stage, the clamping arm 603 swings outward and opens, releasing the sleeve shaft 502, causing the turbulence component 500 to rotate in the opposite direction at high speed under the drive of the torsion spring 505, generating violent turbulence. Step 4: The open clamping arm 603 can cut into and scoop up the material deposited below the preparation tank 100, turn it upward and stir the material; Step 5: During the mixing process, when the temperature of the preparation tank 100 is too high, cooling gas is passed through the jet assembly 700 and evenly injected into the material from the nozzle 709 of the nozzle 707 to achieve temperature control. Step Six: After the materials reach the predetermined mixing degree, stop the equipment and discharge the prepared materials from the preparation tank 100 for subsequent processing.
