Description

Preparation method and processing equipment of microcapsule with ultraviolet shielding function TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical engineering, in particular to a preparation method and processing equipment of microcapsule with ultraviolet shielding function. BACKGROUND

[0002] In electrical engineering, insulation materials are a kind of key materials used for isolating and protecting electrical equipment and circuit elements to ensure their safe operation, however, long-term exposure to ultraviolet radiation can cause the aging and degradation of the microcapsule shell material inside the insulation material, thereby affecting its performance and service life.

[0003] In the prior art, in order to delay the aging and degradation of the microcapsule shell material, various schemes have been proposed, one of which is to add organic ultraviolet absorbers to the microcapsule shell material, these absorbers can absorb and convert ultraviolet radiation, thereby reducing the damage to the microcapsule shell material, however, this method has some limitations, such as poor stability and durability of organic absorbers, which are easily affected by heat and light, and its ultraviolet absorption effect may weaken over time; another implementation scheme is to use nanoparticles to enhance the ultraviolet shielding performance of the microcapsule shell material, for example, by adding titanium dioxide nanoparticles to the microcapsule shell material, excellent ultraviolet shielding effect can be achieved.

[0004] However, the existing microcapsule shell material still has some defects, especially when exposed to ultraviolet radiation for a long time, these defects may include aging, degradation or damage of the shell material, thereby causing the active ingredients inside the microcapsule to be exposed to ultraviolet light, losing the protection effect, secondly, the size and distribution of the microcapsule may not be uniform, resulting in inconsistency of the ultraviolet shielding effect, at the same time, when making these microcapsules, processing equipment is used to stir and mix the raw materials uniformly, however, the stirring range and stirring depth of the existing processing and stirring equipment are mostly fixed, and cannot be adjusted according to the production specifications, the flexibility of use is low, based on this, we propose a microcapsule preparation with ultraviolet shielding function to solve the above problems.

[0005] SUMMARY

[0006] In view of the above problems existing in the prior art of microcapsule preparation with ultraviolet shielding function, the present application is proposed.

[0007] Therefore, the purpose of the present application is to provide a microcapsule preparation with ultraviolet shielding function, which aims to prolong the service life of the microcapsule, achieve consistent ultraviolet shielding effect, and improve the industrial production capacity of the microcapsule.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a microcapsule preparation method with ultraviolet shielding function, comprising the following steps,

[0009] S1. Synthesizing materials with ultraviolet shielding function:

[0010] a. Synthesis of SiO2-coated TiO2 nanoparticles: TiO2 nanoparticles were dispersed in a mixed solution of ethanol, deionized water and ammonia. The mixture was mechanically stirred and ultrasonically treated using a processing device. Tetraethoxysilane dissolved in ethanol was added to the mixture, and stirring was continued. The mixture was then centrifuged, washed and dried to obtain SiO2-coated TiO2 nanoparticles.

[0011] b. Synthesis of SiO2-coated TiO2 nanoparticles containing UV absorbers: When synthesizing SiO2-coated TiO2 nanoparticles, an appropriate amount of UV absorber is added to the mixed solution, and appropriate stirring and ultrasonic treatment are performed.

[0012] S2. Preparation of microcapsules containing ultraviolet shielding materials:

[0013] a. Preparation of coating material solution: Prepare a polyphenylene sulfide resin solution as a carrier material; add SiO2-coated TiO2 nanoparticles and other desired components, such as fluorescent agents or dyes, to the carrier material solution, and stir and sonicate to obtain a uniformly dispersed mixture.

[0014] b. Preparation of microcapsules using the water-in-oil method: The coating material solution is added dropwise to an oil droplet or oil phase with UV shielding function. While stirring, the oil droplet is added to the aqueous phase at an appropriate rate to form microcapsules. The stirring speed and temperature are controlled to promote the formation and stability of the microcapsules.

[0015] c. Microcapsules are prepared using the coprecipitation method: The coating material solution is added dropwise to the polymer particle solution. While stirring, the two solutions are thoroughly mixed to form microcapsules. The stirring speed and temperature are controlled to obtain uniformly dispersed microcapsules.

[0016] S3. Post-processing microcapsules:

[0017] a. Forming a protective layer: A protective layer is formed on the surface of the microcapsules. This can be achieved by coating with a polymer. The coating material solution is added to the microcapsule suspension and then stirred and sonicated to obtain a uniform coating layer.

[0018] b. Washing and centrifugation: The microcapsule suspension is washed repeatedly with alternating ethanol and deionized water to remove residual solvent and impurities. The microcapsules are then separated by centrifugation, and the washing solution is removed.

[0019] c. Drying: The microcapsules are dried in a vacuum oven to remove residual solvent and obtain the final microcapsule product.

[0020] The beneficial effects of this invention are as follows: By using materials with good durability and chemical stability as microcapsule shells, the long-term stability and durability of the microcapsules are ensured. Furthermore, by adding enhancers with higher UV absorption capacity and photostability to the shells, the UV shielding effect and stability of the microcapsules are improved, thereby extending their lifespan and enhancing their durability and stability. This allows for longer protection of the target substance from UV radiation damage. By improving the microcapsule shell preparation process, a more uniform and consistent UV shielding effect is achieved, ensuring that the protective effect of each microcapsule is similar and improving the overall UV shielding performance.

[0050] Example 1

[0051] Referring to Figure 1, which illustrates the first embodiment of the present invention, a method for preparing microcapsules with ultraviolet shielding function is provided. This method includes the following steps:

[0052] S1. Synthesizing materials with ultraviolet shielding function:

[0053] a. Synthesis of SiO2-coated TiO2 nanoparticles: TiO2 nanoparticles were dispersed in a mixed solution of ethanol, deionized water and ammonia. The mixture was mechanically stirred and ultrasonically treated using a processing device. Tetraethoxysilane dissolved in ethanol was added to the mixture, and stirring was continued. The mixture was then centrifuged, washed and dried to obtain SiO2-coated TiO2 nanoparticles.

[0054] b. Synthesis of SiO2-coated TiO2 nanoparticles containing UV absorbers: When synthesizing SiO2-coated TiO2 nanoparticles, an appropriate amount of UV absorber is added to the mixed solution, and appropriate stirring and ultrasonic treatment are performed.

[0055] S2. Preparation of microcapsules containing ultraviolet shielding materials:

[0056] a. Preparation of coating material solution: Prepare a polyphenylene sulfide resin solution as a carrier material; add SiO2-coated TiO2 nanoparticles and other desired components, such as fluorescent agents or dyes, to the carrier material solution, and stir and sonicate to obtain a uniformly dispersed mixture.

[0057] b. Preparation of microcapsules using the water-in-oil method: The coating material solution is added dropwise to an oil droplet or oil phase with UV shielding function. While stirring, the oil droplet is added to the aqueous phase at an appropriate rate to form microcapsules. The stirring speed and temperature are controlled to promote the formation and stability of the microcapsules.

[0058] c. Microcapsules are prepared using the coprecipitation method: The coating material solution is added dropwise to the polymer particle solution. While stirring, the two solutions are thoroughly mixed to form microcapsules. The stirring speed and temperature are controlled to obtain uniformly dispersed microcapsules.

[0059] S3. Post-processing microcapsules:

[0060] a. Forming a protective layer: A protective layer is formed on the surface of the microcapsules. This can be achieved by coating with a polymer. The coating material solution is added to the microcapsule suspension and then stirred and sonicated to obtain a uniform coating layer.

[0061] b. Washing and centrifugation: The microcapsule suspension is washed repeatedly with alternating ethanol and deionized water to remove residual solvent and impurities. The microcapsules are then separated by centrifugation, and the washing solution is removed.

[0062] c. Drying: The microcapsules are dried in a vacuum oven to remove residual solvent and obtain the final microcapsule product.

[0063] During use, materials with good durability and chemical stability are used as microcapsule shells to ensure the long-term stability and durability of the microcapsules. Enhancers with higher UV absorption capacity and photostability are added to the shells to improve the UV shielding effect and stability of the microcapsules, thereby extending their lifespan and improving their durability and stability. This allows for longer protection of the target substance from UV radiation damage. By improving the preparation process of the microcapsule shells, a more uniform and consistent UV shielding effect is achieved, ensuring that the protective effect of each microcapsule is similar and improving the overall UV shielding performance.

[0064] Example 2

[0065] Referring to Figures 2-6, a second embodiment of the present invention is provided, which offers a microcapsule preparation and processing apparatus with ultraviolet shielding function, comprising,

[0066] The support unit 100 includes a base 101, a support rod 102 vertically mounted on the base 101, an adjustment clip 103 mounted on the support rod 102, a controller 104 mounted on the side of the adjustment clip 103, and an extension rod 105 mounted behind the controller 104. The adjustment clip 103 slides along the support rod 102, thereby driving the stirring unit 200 to adjust its vertical height. The extension rod 105 can be rotated to push the controller 104 to slide horizontally, thereby adjusting the horizontal position of the stirring unit 200. Through free adjustment in both the vertical and horizontal directions, the stirring and mixing position can be adjusted according to the initial usage requirements.

[0067] The stirring unit 200 includes a drive motor 201 vertically mounted on the controller 104, a drive component 202 located at the axis of the drive motor 201 and extending downward to below the controller 104, two sets of agitating components 203 located on both sides below the drive component 202 and arranged in a ring around the drive component 202, a top support 204 located above the drive component 202 and with both ends abutting against the tops of the two sets of agitating components 203, and a reinforcing component 205 sleeved on the drive component 202 and extending to the center of the agitating components 203. The drive motor 201 drives the drive component 202 to rotate, and the rotating drive component 202 stirs the material through the two sets of agitating components 203 below. The drive motor 201 is regulated and controlled by the controller 104, that is, the speed and direction of the drive motor 201 are regulated and controlled by the controller 104.

[0068] The adjustment unit 300 includes a fixing component 301 disposed at the end of the driving component 202, two sets of pushing components 302 distributed in a ring on both sides of the fixing component 301, and a limiting component 303 disposed inside the fixing component 301. The fixing component 301 is engaged with the end of the driving component 202 through the limiting component 303, and the fixing component 301 is engaged with the end of the driving component 202 through the pushing components 302. The engagement relationship between the two can be controlled by adjusting the limiting component 303. When the two are not engaged, the fixing component 301 can rotate at the end of the driving component 202, and the rotating limiting component 303 can push the two sets of stirring components 203 to move outward, thereby achieving the purpose of adjusting the stirring range of the stirring components 203.

[0069] During use, the materials to be mixed are placed in a container and positioned directly below the mixing unit 200. Based on the actual mixing requirements, the mixing position is initially adjusted using the adjusting clamp 103 and the extension rod 105. Then, the mixing range of the mixing unit 200 is adjusted using the adjusting unit 300. After adjustment, the drive motor 201 is controlled by the controller 104, which in turn drives the drive component 202 to move the stirring component 203 to perform mixing.

[0070] The driving component 202 includes a vertically arranged driving rod 202a, a threaded section 202b located in the middle of the driving rod 202a, with a top support 204 sleeved on the threaded section 202b, a limiting gear 202c located at the end of the driving rod 202a, with a fixing component 301 sleeved on the outside of the limiting gear 202c, and a reinforcing block 202d fixedly disposed between the limiting gear 202c and the driving rod 202a, with both ends of the reinforcing block 202d extending outwards. The threaded section 202b on the driving rod 202a only exists in the middle part, so the lower half of the outer wall of the driving rod 202a is still smooth, and the movable ring 205a can slide freely on its smooth surface. The limiting gear 202c has multiple sets of locking teeth, and a locking groove is provided between every two sets of locking teeth. The limiting teeth 303b can be locked into the locking groove, thereby limiting the entire limiting component 303.

[0071] The stirring component 203 includes two sets of vertically staggered stirring paddles 203a, with the two sets of stirring paddles 203a on the same spiral line, a connecting shaft 203b between the two sets of stirring paddles 203a, and the outer end of the reinforcing component 205 sleeved on the connecting shaft 203b, and a sleeve 203c disposed at the top of the upper stirring paddle 203a, with the sleeve 203c slidably sleeved on both ends of the top support component 204.

[0072] Furthermore, the stirring paddle 203a is spiral in shape. The spiral stirring structure causes the mixture to generate a radial convection motion when rotating. The material is pushed towards the edge of the container along the spiral of the stirring paddle 203a, and then returns to the stirring component 203 along the wall of the container, forming a spiral-like liquid flow path. The stirred material rises and falls continuously as the spiral blades rotate, circulating in a cycle. At the same time, the mixture also rotates along the wall of the container, making the material inside the mixture more evenly mixed together.

[0073] Furthermore, the stirring component 203 also includes a telescopic rod 203d that is laterally disposed at the end of the stirring paddle 203a and extends into the reinforcing block 202d, a limiting rod 203e disposed on the telescopic rod 203d and extending downward into the pushing component 302, and a bottom stirring plate 203f located below the telescopic rod 203d and fixedly connected at one end to the end of the stirring paddle 203a.

[0074] During use, the stirring paddle 203a is made of a highly resilient material, which can elastically deform downwards when subjected to vertical pressure. This downward deformation changes the overall height of the stirring paddle 203a. The telescopic rod 203d extends into the reinforcing block 202d, whereby it is limited by the reinforcing block 202d and can only slide horizontally along the slot on the reinforcing block 202d. It can also rotate with the drive component 202 when it rotates, thereby driving the stirring component 203 to perform stirring and mixing. The telescopic rod 203d has two sets of quarter-circle strip structures, which are symmetrically arranged and have a clearance groove between them. Therefore, the telescopic rods 203d of the two stirring components 203 can overlap on the same axis. The two overlapping and coaxial telescopic rods 203d can reduce the additional space occupied when stored.

[0075] The top support 204 includes a collar 204a sleeved on the drive rod 202a, support rods 204b symmetrically arranged on both sides of the collar 204a and extending into the sleeve 203c, a threaded sleeve 204c disposed below the collar 204a and threadedly sleeved onto the threaded section 202b, and a limiting sleeve 204d disposed above the threaded sleeve 204c and extending upward into the collar 204a. The sleeve 203c can slide horizontally on the support rod 204b, while the collar 204a is rotatably connected to the drive rod 202a and is not threadedly connected to the threaded section 202b. The collar 204a is rotatably connected to the threaded sleeve 204c through the limiting sleeve 204d. When the threaded sleeve 204c moves on the threaded section 202b by rotation, it can drive the collar 204a to move accordingly.

[0076] The reinforcing component 205 includes a movable ring 205a sleeved on the driving component 202, storage rods 205b symmetrically arranged on both sides of the movable ring 205a, a sleeve 205c inserted into the storage rods 205b, and a sleeve shaft 205d disposed at the outer end of the sleeve 205c and sleeved on the connecting shaft 203b. The reinforcing component 205 is disposed between the two sets of stirring components 203. The storage rods 205b on both sides are located between the two sets of stirring paddles 203a, which can enhance the stability between the stirring components 203 and ensure their safety during rotation. The sleeve 205c can slide on the storage rods 205b to adjust according to the position of the stirring components 203.

[0077] During use, according to actual needs, the threaded sleeve 204c is rotated. The threaded sleeve 204c, through its threaded connection with the threaded section 202b, drives the top support 204 to move vertically. The moving top support 204 will press the stirring paddle 203a downward through the support rods 204b on both sides, causing the stirring paddle 203a to deform and compress downward. The downward deformation of the stirring paddle 203a makes the overall spiral range of the stirring component 203 lower, but the diameter of the spiral line remains unchanged. Therefore, the spiral stirring effect of the stirring component 203 remains unchanged. The stirring depth of the stirring component 203 in the container being stirred also changes due to the lower height, thereby achieving the purpose of further adjusting the stirring depth and meeting more usage needs.

[0078] The remaining structure is the same as that in Example 1.

[0079] Example 3

[0080] Referring to Figures 7 to 10, this is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the stirring range can be adjusted according to needs to meet more usage requirements.

[0081] Compared to Embodiment 2, the fixing component 301 further includes a fixing sleeve 301a sleeved on the outside of the limiting gear 202c, a relief groove 301b opened on one side inside the fixing sleeve 301a, the relief groove 301b having a half-circular arc structure, spring grooves 301c symmetrically opened at both ends of the relief groove 301b, and an opening groove 301d opened on the other side inside the fixing sleeve 301a, one side of the opening groove 301d having an open structure communicating with the outside.

[0082] The pushing component 302 includes a pushing clamp 302a that is annularly distributed on both sides of the fixed sleeve 301a, and a pushing groove 302b opened inside the pushing clamp 302a. The pushing groove 302b has an arc structure, and the limiting rod 203e extends into the pushing groove 302b. The pushing component 302 has an arc structure as a whole. The limiting rod 203e located in the pushing groove 302b is pushed and limited by the pushing groove 302b. When the pushing component 302 rotates around the driving component 202, the pushing component 302 will push and squeeze the limiting rod 203e through the inside of the pushing clamp 302a, causing it to move.

[0083] The limiting component 303 includes a limiting frame 303a located in the clearance groove 301b, multiple sets of limiting teeth 303b disposed inside the limiting frame 303a and engaged with the sleeve 203c, two sets of return springs 303c symmetrically disposed at both ends of the limiting frame 303a and respectively located in two sets of spring grooves 301c, a connecting frame 303d symmetrically disposed on one side of the limiting frame 303a and located in the opening groove 301d, and a top block 303e disposed on the connecting frame 303d and extending one end through the opening groove 301d to the outside of the fixing sleeve 301a.

[0084] During use, adjust the horizontal stirring range of the stirring component 203 according to the usage requirements. By pressing the top block 303e, the top block 303e will press the limiting tooth 303b along the relief groove 301b through the connecting frame 303d. At this time, the limiting tooth 303b disengages from the slot of the limiting gear 202c, and the two are no longer locked. At the same time, the return springs 303c located at both ends of the connecting frame 303d retract and store energy. At this time, the adjusting unit 300 can be rotated as a whole with the limiting gear 202c as the axis. The pushers 302 on both sides push the limit rod 203e to move horizontally. The horizontally displaced stirring component 203 moves outward away from the drive component 202. The connection between the top support 204 and the reinforcing component 205 and the stirring component 203 will also change accordingly. The two sets of stirring components 203 move synchronously, which can adjust the horizontal stirring range included by the two sets of stirring components 203, thereby meeting more usage needs.

[0085] The remaining structure is the same as that in Example 2.

The mixture was mechanically stirred and ultrasonically treated using a processing device. Tetraethoxysilane dissolved in ethanol was added to the mixture, and stirring was continued. The mixture was then centrifuged, washed and dried to obtain SiO2-coated TiO2 nanoparticles. b. Synthesis of SiO2-coated TiO2 nanoparticles containing UV absorbers: When synthesizing SiO2-coated TiO2 nanoparticles, an appropriate amount of UV absorber is added to the mixed solution, and appropriate stirring and ultrasonic treatment are performed. S2. Preparation of microcapsules containing ultraviolet shielding materials: a. Preparation of coating material solution: Prepare a polyphenylene sulfide resin solution as a carrier material; add SiO2-coated TiO2 nanoparticles and other desired components, such as fluorescent agents or dyes, to the carrier material solution, and stir and sonicate to obtain a uniformly dispersed mixture. b. Preparation of microcapsules using the water-in-oil method: The coating material solution is added dropwise to an oil droplet or oil phase with UV shielding function. While stirring, the oil droplet is added to the aqueous phase at an appropriate rate to form microcapsules. The stirring speed and temperature are controlled to promote the formation and stability of the microcapsules. c. Microcapsules are prepared using the coprecipitation method: The coating material solution is added dropwise to the polymer particle solution. While stirring, the two solutions are thoroughly mixed to form microcapsules. The stirring speed and temperature are controlled to obtain uniformly dispersed microcapsules. S3. Post-processing microcapsules: a. Forming a protective layer: A protective layer is formed on the surface of the microcapsules. This can be achieved by coating with a polymer. The coating material solution is added to the microcapsule suspension and then stirred and sonicated to obtain a uniform coating layer. b. Washing and centrifugation: The microcapsule suspension is washed repeatedly with alternating ethanol and deionized water to remove residual solvent and impurities. The microcapsules are then separated by centrifugation, and the washing solution is removed. c. Drying: The microcapsules are dried in a vacuum oven to remove residual solvent and obtain the final microcapsule product.
