Description

Technical Field

[0001] The present invention relates to the technical field of electrical engineering, and particularly to a method for preparing microcapsules with an ultraviolet shielding function and a processing apparatus therefor.

Background Art

[0002] In electrical engineering, insulating materials are important materials used to isolate and protect electrical devices and circuit elements so that they can operate safely. However, when exposed to ultraviolet radiation for a long time, it may cause deterioration and biodegradation of the microcapsule shell material inside the insulating material, which may affect its performance and service life.

[0003] In the prior art, various solutions have been proposed to delay the deterioration and biodegradation of the microcapsule shell material. Among them, a common one is to add an organic ultraviolet absorber to the microcapsule shell material. These absorbers can absorb and convert ultraviolet radiation, thereby reducing damage to the microcapsule shell material. However, such a method has some limitations, for example, the stability and durability of the organic absorber are low, it is easily affected by heat and light, and its ultraviolet absorption effect may weaken over time. Another implementation means is to enhance the ultraviolet shielding performance of the microcapsule shell material by nanoparticles. For example, by adding titanium dioxide nanoparticles to the microcapsule shell material, an excellent ultraviolet shielding effect can be achieved.

[0004] However, conventional microcapsule shell materials still have several drawbacks, particularly when exposed to ultraviolet radiation for extended periods. These drawbacks include degradation, biodegradation, or damage to the shell material, which exposes the active ingredients inside the microcapsules to ultraviolet light, resulting in a loss of protective effect. Furthermore, the dimensions and distribution of the microcapsules may be non-uniform, leading to inconsistent UV shielding effects. Additionally, while processing equipment is used to uniformly stir and mix the raw materials during the preparation of these microcapsules, conventional processing and stirring equipment often has a fixed stirring range and depth, making it difficult to adjust according to production specifications and resulting in low flexibility. Based on these issues, we propose the preparation of microcapsules with UV shielding capabilities to solve the above problems. [Overview of the project]

[0005] In view of the problems associated with the preparation of conventional microcapsules with UV-shielding capabilities, we propose the present invention.

[0006] Therefore, the present invention aims to provide a method for preparing microcapsules with ultraviolet shielding function, thereby extending the service life of microcapsules, achieving consistent ultraviolet shielding effects, and improving the industrial production capacity of microcapsules.

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 sonication are performed. S2. Step for preparing microcapsules containing UV shielding material: a. Preparation of coating solution: A polyphenylene sulfide resin solution is prepared as the carrier material, SiO2-coated TiO2 nanoparticles and other necessary components, such as fluorescent agents or dyes, are added to the carrier material solution, and stirring and ultrasonic treatment are performed to obtain a uniformly dispersed mixture. b. Preparation of microcapsules by the water-in-oil method: A coating solution is added dropwise to an oil droplet or oil phase with UV shielding properties, and 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. Preparation of microcapsules by coprecipitation: The coating solution is added dropwise to the polymer particle solution, and the two solutions are thoroughly mixed while stirring to form microcapsules. The stirring speed and temperature are controlled to obtain uniformly dispersed microcapsules. S3. Post-processing steps for microcapsules: a. Formation of protective layer: A protective layer can be formed on the surface of the microcapsules and coated with a polymer. The coating solution is added to the microcapsule suspension, stirred, and ultrasonically treated to obtain a uniform coating layer. b. Washing and centrifugation: The microcapsule suspension is washed repeatedly with alternating ethanol and deionized water to remove any remaining solvent and impurities, and the microcapsules are separated by centrifugation, and the washing solution is removed. c. Drying: The microcapsules are dried in a vacuum oven to remove any remaining solvent and obtain the final microcapsule product.

Furthermore, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0026] Example 1 Referring to Figure 1, which is a first embodiment of the present invention, a method for preparing microcapsules having an ultraviolet shielding function is provided, the method comprising the following steps S1 to S3, namely, S1. Synthesis step of a material with UV shielding function: a. Synthesis of SiO2-coated TiO2 nanoparticles: TiO2 nanoparticles are dispersed in a mixed solution of ethanol, deionized water, and ammonia water, mechanically stirred in a processing apparatus and subjected to ultrasonic treatment, tetraethoxysilane dissolved in ethanol is added to the mixture, stirring is continued, followed by centrifugation, washing, and drying to obtain SiO2-coated TiO2 nanoparticles. b.

[0027] In order to ensure the long-term stability and durability of microcapsules during use, materials with good durability and chemical stability are used as the microcapsule shell material. This improves the UV shielding effect and stability of the microcapsules, extends the service life of the microcapsules, and further enhances their durability and stability by adding reinforcing agents with higher UV absorption capacity and photostability to the shell material. This protects the target substance from UV radiation for a longer period. Furthermore, by improving the preparation process of the microcapsule shell material, a more uniform and consistent UV shielding effect is achieved, ensuring a similar protective effect for each microcapsule and improving overall UV shielding performance.

[0028] Example 2 Referring to Figures 2 to 6, which represent a second embodiment of the present invention, a processing apparatus for preparing microcapsules equipped with an ultraviolet shielding function is provided, which, The support unit 100 includes a base 101, a support rod 102 perpendicularly mounted to 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 and drives the stirring unit 200 to adjust its vertical height, and the extension rod 105 can be rotated to propel the controller 104 back and forth horizontally, thereby achieving the objective of adjusting the horizontal position of the stirring unit 200. The support unit 100 allows for initial adjustment of the stirring and mixing position according to usage needs through free adjustment in both vertical and horizontal directions. A drive motor 201 mounted perpendicular to the controller 104, a drive member 202 mounted at the axial position of the drive motor 201 and extending downward through to below the controller 104, two sets of stirring members 203 mounted on both sides below the drive member 202 and distributed in an annular shape with the drive member 202 as its axis, a top support member 204 mounted above the drive member 202 and having both ends abutting the top ends of the two sets of stirring members 203, and the drive member The stirring unit 200 includes a reinforcing member 205 fitted to 202 and extending at both ends to the center of the stirring member 203, the drive motor 201 drives the drive member 202 to rotate, the rotating drive member 202 stirs the material with two sets of stirring members 203 below, the drive motor 201 is adjusted and controlled by the controller 104, that is, the rotation speed and direction of the drive motor 201 are adjusted and controlled by the controller 104, The device includes an adjustment unit 300 comprising a fixed member 301 provided at the end of a drive member 202, two sets of thrusting members 302 distributed annularly on both sides of the fixed member 301, and a position limiting member 303 provided inside the fixed member 301, wherein the fixed member 301 is engaged with the end of the drive member 202 by the position limiting member 303, and the fixed member 301 is engaged with the end of the drive member 202 by the thrusting members 302, and the engagement relationship between the two can be controlled by adjusting the position limiting member 303, and when the two are not engaged, the fixed member 301 can rotate at the end of the drive member 202, and the rotating position limiting member 303 can push the two sets of stirring members 203 to move outward, thereby achieving the purpose of adjusting the stirring range of the stirring members 203.

[0029] During use, the materials to be mixed are stored together in one container, and the container is placed directly below the stirring unit 200. The stirring position is initially adjusted using the adjustment clip 103 and the extension rod 105 according to the actual stirring requirements. Subsequently, the stirring range of the stirring unit 200 is adjusted using the adjustment unit 300. After the adjustment is complete, the controller 104 controls the drive motor 201, which drives the drive member 202, driving the stirring member 203 to perform a stirring and mixing operation.

[0030] Here, the drive member 202 is a vertically mounted drive rod 202a, a threaded portion 202b located in the middle of the drive rod 202a and to which the top support member 204 is fitted, and a position limiting gear 202c provided at the end of the drive rod 202a, and the fixing member 301 is a position limiting gear 202c fitted to the outside of the position limiting gear 202c, and a reinforcing bracket fixedly provided between the position limiting gear 202c and the drive rod 202a, with both ends extending outward. The lock 202d is included, and the threaded portion 202b that is opened on the drive rod 202a is only in the middle section, so the outer wall of the lower half of the drive rod 202a remains smooth, the movable ring 205a can slide freely on its smooth surface, the position limiting gear 202c is provided with multiple sets of locking teeth, a locking groove is provided between every two sets of locking teeth, the position limiting tooth 303b is locked in the locking groove, and the entire position limiting member 303 can be further restricted.

[0031] Here, the stirring member 203 includes two sets of stirring blades 203a distributed vertically offset from each other on the same helical line, a connecting shaft 203b provided between the two sets of stirring blades 203a to which the outer end of the reinforcing member 205 is fitted, and sleeves 203c provided at the top end of the upper stirring blade 203a and slidably fitted to both ends of the top support member 204.

[0032] Furthermore, the stirring blade 203a has an overall helical shape and a helical stirring structure, which causes the mixed liquid to undergo convection motion similar to radial flow when it rotates. The material is pressed against the edge of the container along the helical line of the stirring blade 203a, then stirred along the wall of the container and returned to the stirring member 203, forming a liquid flow path similar to a helical line. The stirred material constantly rises and falls as the helical blade rotates, circulating and flowing, and at the same time, the mixed liquid also rotates along the wall of the container, thereby mixing the material in the mixed liquid more uniformly.

[0033] Furthermore, the stirring member 203 further includes an extendable rod 203d that extends horizontally into the reinforcing block 202d and is provided at the end of the stirring blade 203a, a position limiting rod 203e that extends downward into the pushing member 302 and is provided on the extendable rod 203d, and a bottom stirring plate 203f that is located below the extendable rod 203d and has one end fixedly connected to the end of the stirring blade 203a.

[0034] During use, the stirring blade 203a is made of a material with high toughness and can elastically deform downward when subjected to vertical pressure, and this downward deformation can change the overall height of the stirring blade 203a. The telescopic rod 203d extends into the reinforcing block 202d and is restricted by the reinforcing block 202d, and can only perform horizontal translational sliding along the locking groove provided in the reinforcing block 202d. Furthermore, when the drive member 202 rotates, the rod rotates in accordance with it and can drive the entire stirring member 203 to perform stirring and mixing operations. The structure of the telescopic rod 203d is two sets of strip-shaped structures with a cross-section of a quarter circle. The two sets of strip-shaped structures are installed symmetrically, and there is a relief groove between the two sets of strip-shaped structures. Therefore, the telescopic rods 203d of the two sets of stirring member 203 can overlap on the same axis, and the two sets of telescopic rods 203d that overlap and become coaxial can reduce the extra space occupied when stored.

[0035] Here, the top support member 204 includes a fitting ring 204a fitted onto the drive rod 202a, support rods 204b symmetrically provided on both sides of the fitting ring 204a and extending into the sleeve 203c, a screw sleeve 204c provided below the fitting ring 204a and screwed onto the screw portion 202b, and a position limiting sleeve 204d provided above the screw sleeve 204c and extending upward into the fitting ring 204a, wherein the sleeve 203c can slide horizontally on the support rod 204b, the fitting ring 204a is rotatably connected to the drive rod 202a without being screwed onto the screw portion 202b, the fitting ring 204a is rotatably connected to the screw sleeve 204c by the position limiting sleeve 204d, and the screw sleeve 204c can be driven to move the fitting ring 204a in accordance with it as it moves rotatably on the screw portion 202b.

[0036] Here, the reinforcing member 205 includes a movable ring 205a fitted to the drive member 202, storage rods 205b symmetrically provided on both sides of the movable ring 205a, a sleeve 205c inserted into the storage rods 205b, and a fitting shaft 205d provided at the outer end of the sleeve 205c and fitted to the connecting shaft 203b. The entire reinforcing member 205 is provided between the two sets of stirring members 203 and positioned between the two sets of stirring blades 203a via the storage rods 205b on both sides, thereby strengthening the stability between the stirring members 203 and ensuring safety during rotation. The sleeve 205c can slide in an extendable and retractable manner on the storage rods 205b, thereby achieving the objective of adjusting in accordance with changes in the position of the stirring members 203.

[0037] During use, the screw sleeve 204c is rotated according to the actual needs, and the screw sleeve 204c is driven to move the entire top support member 204 vertically by screwing it with the screw portion 202b. As the top support member 204 moves, the support rods 204b on both sides push down the stirring blade 203a, deforming and compressing the entire stirring blade 203a downwards. The downwardly deformed stirring blade 203a lowers the helical range of the entire stirring member 203, but since the diameter of the helical line does not change, the helical stirring effect of the stirring member 203 does not change. The reduced height of the stirring member 203 also changes the stirring depth in the container being stirred, thereby achieving the objective of further adjusting the stirring depth and meeting a wider range of usage needs.

[0038] The other structural elements are the same as those in Example 1.

[0039] Example 3 Referring to Figures 7 to 10, which represent a third embodiment of the present invention, this embodiment differs from the second embodiment in that the stirring range can be adjusted according to the needs, thereby meeting a wider range of usage needs.

[0040] Compared to Embodiment 2, the fixing member 301 further includes a fixing sleeve 301a fitted to the outside of the position limiting gear 202c, a relief groove 301b with a half-arc structure opened on one side inside the fixing sleeve 301a, spring grooves 301c opened symmetrically at both ends of the relief groove 301b, and an opening groove 301d opened on the other side inside the fixing sleeve 301a, with one side of the opening groove 301d communicating with the outside to form an open structure.

[0041] Here, the thrusting member 302 includes thrusting clips 302a distributed annularly on both sides of the fixed sleeve 301a, and an arc-shaped thrusting groove 302b opened inside the thrusting clips 302a. The position limiting rod 203e extends into the thrusting groove 302b, and the entire thrusting member 302 has an arc-shaped structure. The position limiting rod 203e, located inside the thrusting groove 302b, receives limiting thrust from the thrusting groove 302b. When the entire thrusting member 302 rotates around the drive member 202 as its axis, the thrusting member 302 presses against the position limiting rod 203e due to the internal thrust of the thrusting clips 302a, causing it to move.

[0042] Here, the position limiting member 303 includes a position limiting rack 303a located in the relief groove 301b, a plurality of sets of position limiting teeth 303b provided inside the position limiting rack 303a, the plurality of sets of position limiting teeth 303b which are engaged with the sleeve 203c, two sets of return springs 303c located in two sets of spring grooves 301c, which are symmetrically provided at both ends of the position limiting rack 303a, a connecting frame 303d provided symmetrically on one side of the position limiting rack 303a and located in the opening groove 301d, and a push-up block 303e provided on the connecting frame 303d, with one end extending to the outside of the fixed sleeve 301a via the opening groove 301d.

[0043] During use, the horizontal stirring range of the stirring member 203 is adjusted according to the usage needs, and the push-up block 303e is pressed, causing the push-up block 303e to be pressed by the connecting frame 303d so that the position limiting teeth 303b slide along the relief groove 301b. At this time, the position limiting teeth 303b disengage from the locking groove of the position limiting gear 202c, and the two are no longer engaged. Simultaneously, the return springs 303c located at both ends of the connecting frame 303d contract and store energy, and at this time the entire adjustment unit 300 rotates around the position limiting gear 202c as its axis. The rotating adjustment unit 300 is propelled by the thrusting members 302 on both sides to displace the position limiting rod 203e horizontally. The horizontally displaced stirring member 203 drives the entire stirring member 203 to move outward away from the drive member 202. The connections between the top support member 204 and the reinforcing member 205 to the stirring member 203 also change accordingly. The two sets of stirring members 203 move synchronously, thereby achieving the objective of adjusting the horizontal stirring range by the two sets of stirring members 203 and further meeting a wider range of usage needs.

[0044] The other structural elements are the same as those in Example 2.
