Description

Technical Field

[0001] This invention relates to the field of polymer membrane technology, specifically to an environmentally friendly method for preparing a dual silicone oil membrane. Background Technology

[0002] Silicone oil film generally refers to a very thin and continuous coating of polydimethylsiloxane or its modified derivatives formed on a solid surface, which can significantly change the physicochemical properties of the substrate surface. Dual silicone oil film refers to coating two layers of polydimethylsiloxane on a solid surface, thereby further improving its physicochemical properties.

[0003] The patent application with application number CN202311229757.3 mentions "a heat-resistant high thermal conductivity silicone oil and its preparation method". This patent uses carbon nanotubes and T8-POSS to end-cap silicone oil, and then combines the resulting double-end capped silicone oil with phenylmethyl silicone oil to finally obtain a silicone oil product with excellent heat resistance and thermal conductivity. This silicone oil product improves the flash point, volatility and thermal conductivity of the high thermal conductivity silicone oil.

[0004] However, silicone oil films are prone to performance degradation in high-temperature environments, have insufficient film structure stability, and limited heat aging resistance, making it difficult to meet the application requirements for long-term use or high-temperature conditions. On the other hand, some silicone oil films have low adhesion to the substrate, and are prone to problems such as film peeling and cracking during use or aging, affecting the reliability and service life of the product. In addition, the temperature control during the coating process in traditional silicone oil film preparation is relatively crude, and the film formation conditions are unstable, which can easily lead to uneven film thickness and large internal stress, thereby further weakening the overall performance of the silicone oil film.

[0029] According to the above technical solution, the comprehensive raw material system of the first silicone oil film and the second silicone oil film includes, by weight percentage: 60% siloxane base oil, 10% modified silicone resin, 4.5% structural stabilizer, 2.0% crosslinking component, 0.3% reaction promoter, 14% environmentally friendly dispersion medium, 1.3% rheology modifier, 0.3% defoaming agent, 2.2% weather resistance enhancer, 1.2% heat aging resistance agent, 1.8% inorganic nanofiller, 1.4% flexible polymer resin, 0.6% surface energy regulator, and 0.4% adhesion promoter.

[0032] The following table compares Examples 1-3:

[0033] As can be seen from the above comparative data, there are significant differences in the film thickness, adhesion and heat aging resistance of the silicone oil films prepared in different embodiments. The film thickness of the silicone oil films formed in the three embodiments is controlled within a narrow range, indicating that the preparation process has good film formation controllability.

[0034] Among them, the silicone oil film prepared in Example 1 achieved an adhesion grade of 0 with a film thickness of 1.2 μm and a heat aging time of 240 h at 120℃, which is significantly better than that in Examples 2 and 3. This indicates that under the raw material ratio and process parameters used in Example 1, the bond between the silicone oil film and the substrate is stronger and the film structure has higher stability.

[0035] In contrast, although Examples 2 and 3 can also form continuous and complete silicone oil films, their adhesion level and heat aging resistance are reduced, indicating that their film density and high temperature stability are relatively weak. It can be seen that by reasonably controlling the raw material system and coating processing conditions of the silicone oil film, especially the film-forming parameters, the overall performance of the silicone oil film can be effectively improved. Among them, the technical solution corresponding to Example 1 shows better technical effect.

A fixed material operation frame 410 is slidably installed at one end of the load-bearing fixed card frame 303; The top of the fixed material operation frame 410 is symmetrically connected with the clamping electric slide rail 411. The top of the clamping electric slide rail 411 is mounted with the clamping operation plate 412 through the slide rail seat. The tensioning sliding block 402 is slidably installed inside the fixed card integration frame 301, the multi-protrusion card limit frame 302 and the load-bearing fixed card frame 303. The fixed material operation frame 410 is placed inside the outer partition limit box 1. The clamping operation plate 412 is slidably installed inside the fixed material operation frame 410 to realize the tensioning and loosening of plastic film and the feeding and discharging guidance operation. The double-row arc plate 327 has overflow treatment ports 413 symmetrically opened on its side ends; One end of the load-bearing fixed clamp frame 303 is slidably connected to the traction processing roller 408 with a clamping fixed roller 414, and one end of the load-bearing fixed clamp frame 303 is clamped with a fixed clamping rod 420. The fixed clamping rod 420 and the clamping roller 414 are rotatably connected to a supporting synchronous block 415. The longitudinal section of the supporting synchronous block 415 is L-shaped to achieve clamping and positioning. A spring clamping rod 416 is installed between the two supporting synchronous blocks 415. One end of the injection tank 326 is connected to an injection fixing pipe 417, and a processing valve 418 is embedded in the other end of the injection fixing pipe 417. A locking cover 419 is hinged at one end of the outer partition box 1 at the position corresponding to the material control frame 410, and an isolation discharge box 409 is connected through one end of the outer partition box 1. To ensure stable operation of the equipment, the input terminals of the tensioning electric slide rail 401, the constant temperature electric oven 405, the traction electric slide rail 407, the clamping electric slide rail 411, and the processing valve 418 are all electrically connected to the output terminal of an external controller.

[0039] The working principle and usage process of this invention are as follows: During the production of dual silicone oil film, the operator rotates the closing sealing cover 419 to open the outer partition limiting box 1, pulls the material fixing operation frame 410, and places the plastic film roll onto the material fixing operation frame 410. The clamping operation plate 412 moves in opposite directions via the clamping electric slide rail 411. Through the opposing clamping at both ends and position fine-tuning, the position of the plastic film roll is quickly corrected. After correction, the material fixing operation frame 410 is pushed into the side of the load-bearing fixed clamp frame 303 and completely placed inside the outer partition limiting box 1. After feeding, the operator pulls the plastic film, allowing it to pass through the fixed pulling smooth roller 404 and the clamping fixing roller 414. The plastic film moves to the moving pressing roller 323, passes through the moving pressing roller 323 and enters the position of the guide tension roller 403 located inside the load-bearing fixed card frame 303, and contacts the second group of moving pressing rollers 323 again. Then it moves again to the guide tension roller 403 located at the fixed card integration frame 301. Under the pull, the plastic film is moved to the position of the fourth group of moving pressing rollers 323. Then it passes through the moving pressing roller 323 located at the position of the multi-convex card limit frame 302 and contacts the fourth group of moving pressing rollers 323. Then it is discharged through the fixed pull smooth roller 404, constant temperature electric oven 405, traction processing roller 408 and fixed pull smooth roller 404, realizing the complete feeding and pulling processing of the plastic film. When the plastic film moves to the position of the fixed clamping rod 420, the spring pressing rod 416 drives the supporting synchronous block 415 to move along the load-bearing fixed clamping frame 303, pushing the clamping fixing roller 414 to move along the load-bearing fixed clamping frame 303 to the position of the traction processing roller 408. The clamping fixing roller 414 and the traction processing roller 408 are used to press and clamp the film, realizing the flattening and tension restriction of the film during discharge. When the film moves to the position of the traction electric slide rail 407 at the top of the load-bearing fixed clamping frame 303, the traction electric slide rail 407 drives the traction processing roller 408 to pull the film for tension adjustment, in conjunction with the load-bearing fixed clamping rod 420. The fixed-pulling smooth roller 404 on the top inner side of the card holder 303 provides support. When the film moves to the position of the fixed-pulling smooth roller 404, it is located between the two air inlet guide boxes 304. At this time, the guide treatment plate 307 is driven to rotate along the air inlet guide box 304 by the fixed-rotation motor 306 and the multi-axis belt drive box 305. The angle of the guide treatment plate 307 is adjusted according to the moving speed of the film. Ionic fresh air is injected into the air inlet guide box 304 through the self-filtering ion fresh air machine 309 and the air inlet fixed pipe 308. The ion fresh air directly blows the top and bottom of the film to remove static electricity, so that the dust and impurities attached to the film surface lose the static attraction. The processed film moves along the fixed-tension smooth roller 404 to the traction electric slide rail 407 located at the multi-convex limit frame 302. At this time, the film is between the inlet and outlet of the slag removal box 310, and its side end is in contact with the side end of the ultrasonic vibrator 312. The ultrasonic vibrator 312 emits ultrasonic waves to generate vibration, causing the film to oscillate slightly. Through small-amplitude and rapid oscillation, the dust and impurities attached to the film surface are shaken up. At the same time, clean air is injected into the diversion guide frame 311 through the self-filter air pump 314 and the air intake operation pipe 313. The air is injected into the dust raised by the ultrasonic vibration at an inclined state along the diversion guide frame 311. At the location of impurities, air inside the inlet / outlet deslagging box 310 is drawn out by the vacuum cleaner 316 and the vacuum operation pipe 315, creating a negative pressure chamber inside. External air is drawn into the inside of the inlet / outlet deslagging box 310, and air is drawn in through the middle and discharged through the edges, forming a U-shaped extraction airflow channel. The dust impurities that are shaken and floated are sucked out, thus achieving membrane deslagging treatment. After deslagging, the membrane is moved to the position of the corona treatment rack 319. At this time, the surface of the membrane is corona treated by the corona processor 320, which makes the surface of the membrane rougher and increases its wettability to polar solvents, thereby increasing the adhesion of the membrane surface. After corona treatment, the film moves to the position of the moving pressing roller 323. At this time, the pressing hydraulic cylinder 321 drives the pressing processing block 322 and the moving pressing roller 323 to push the film downward. At this time, the injection fixing pipe 417 is opened through the processing valve 418, and polydimethylsiloxane is injected into the inner side of the serial injection tank 326. With the help of the overflow processing port 413, the polydimethylsiloxane is circulated, ensuring that the silicone oil supply liquid level is always unique and controlling the position of the micro-concave coating roller 333 adhering to the polydimethylsiloxane. The pump 329 and the injection operation pipe 328 draw out the polydimethylsiloxane in the serial injection tank 326. The polydimethylsiloxane is injected into the inner side of the double-row arc plate 327 through the injection operation pipe 328. The micro-adjustment electric slide rail 325 drives the serial injection tank 326 and the double-row arc plate 327 to move upward. The micro-gravure coating roller 333 is raised, and the contact position between the bottom of the roller and the polydimethylsiloxane is adjusted. The brushless speed motor 330 and the irregular belt drive box 324 drive the moving pressing roller 323 to rotate. The moving pressing roller 323 pushes the film to move. The brushless speed motor 330 drives the micro-gravure coating roller 333 to rotate along the polydimethylsiloxane, so that the polydimethylsiloxane adheres to the outer end of the micro-gravure coating roller 333, realizing the material application. The pressure position electric push rod 331 drives the linkage doctor blade 332 to move, so that the side end of the linkage doctor blade 332 contacts the side end of the micro-gravure coating roller 333, controlling the thickness of the polydimethylsiloxane on the outer side of the micro-gravure coating roller 333. When the side end of the micro-gravure coating roller 333 contacts the film surface, the polydimethylsiloxane is transferred to the film surface, realizing the first polydimethylsiloxane coating process. The film moves along the moving pressing roller 323. The end of the film without polydimethylsiloxane coating is at the side of the guide tension roller 403. The tension sliding block 402 moves along the load-bearing fixed bracket 303 via the tension sliding rail 401. The tension sliding block 402 then moves the guide tension roller 403, which in turn pushes the film to adjust its surface tension, preventing the coated polydimethylsiloxane from sticking together. As the film moves along the load-bearing fixed bracket 303, ultraviolet light is emitted by the UV curing instrument 335 for UV curing, achieving rapid curing of the polydimethylsiloxane on the film surface. After curing, the polydimethylsiloxane is measured by an optical thickness gauge 336. Optical thickness measurement is performed, and the above coating process is repeated to coat the uncoated end of the film with polydimethylsiloxane. UV curing and optical thickness measurement are repeated. The film with the first layer of silicone oil coating is guided by the tension roller 403 in the fixed clamping frame 301 and enters the position of the third set of moving pressing rollers 323. At this time, the coating process is repeated. The UV curing instrument 335 is rotated by the fine-tuning rotary cylinder 334. The angle of the UV curing instrument 335 is adjusted according to the angle of film movement to achieve repeated coating and curing. Through four-stage coating, the coating process is refined and separated to avoid the coated plastic film directly contacting the supporting components, which could damage the polydimethylsiloxane. After being fully coated and preliminarily cured, the double silicone film moves along the fixed-clamp linkage roller 406 to the constant temperature electric oven 405. The constant temperature electric oven 405 performs low-temperature slow curing of the double silicone film, realizing the repeated curing treatment of polydimethylsiloxane. In conjunction with the traction electric slide rail 407, multiple sets of traction processing rollers 408 move, pulling the double silicone film to ensure the uniformity of its surface tension and the flatness of its surface during the curing and cooling process, avoiding unevenness on the surface of the double silicone film and improving product quality.

[0040] A pressure-reducing removal component 3 is installed. A fixed-rotation motor 306 and a multi-axis belt drive box 305 drive the guide plate 307 to adjust the exhaust port size of the air inlet guide box 304. In conjunction with a self-filtering ion fresh air machine 309 and an air inlet fixed pipe 308, ionized fresh air is injected into the air inlet guide box 304. Utilizing a slow, bidirectional ion airflow from the top and bottom, the membrane moves smoothly while simultaneously undergoing static electricity removal, causing dust and impurities on the membrane surface to lose their adsorption capacity. Then, an ultrasonic vibrator 312 performs small-amplitude ultrasonic vibrations on the membrane, in conjunction with the self-filtering ion fresh air machine 309 and an air inlet fixed pipe 308. Air is injected by the air pump 314 and the air intake operation pipe 313, and air is drawn out by the vacuum cleaner 316 and the vacuuming operation pipe 315. The air flows along the diversion guide frame 311 through the intake, and is sucked in by the negative pressure air chamber in the middle to form a U-shaped airflow channel. The airflow channel attracts the dust that is shaken and floats up and discharges the dust. Through static electricity removal, ultrasonic vibration and synchronous airflow of intake and exhaust, the slag removal treatment is carried out to achieve low contact slag removal treatment on the surface of the film substrate, reduce the probability of contact scratches on the surface of the film substrate, improve the cleanliness of the substrate surface and ensure the quality of the substrate. The film surface is corona treated by a corona treatment frame 319 and a corona processor 320 to increase the adhesion of the film surface. A downward hydraulic cylinder 321 drives a downward treatment block 322 and a moving pressing roller 323 to push the film downward, adjusting the distance between the film and the gravure coating roller 333. Simultaneously, a liquid pump 329, a liquid injection operation pipe 328, a double-row arc plate 327, and a fine-tuning electric slide rail 325 circulate the polydimethylsiloxane liquid, adjusting the distance between the bottom of the gravure coating roller 333 and the polydimethylsiloxane. The contact depth of polydimethylsiloxane is controlled by a brushless variable speed motor 330, a micro-grooving coating roller 333, a pressure-positioning electric push rod 331, and a linkage doctor blade 332. The thickness of the polydimethylsiloxane is monitored in conjunction with an optical thickness gauge 336. By enhancing the adhesion ability of the film substrate and adjusting the thickness and position of the polydimethylsiloxane, the production process can be controlled according to the thickness of the substrate and the actual adhesion, ensuring the uniformity of the overall production and the quality of the product. By combining static electricity removal, oscillating airflow for slag removal, corona treatment to enhance adhesion, and multi-segment adhesion thickness adjustment and monitoring, the existing technologies effectively solve the problems of large-scale scratches on the film substrate surface due to slag removal and uneven overall coating of the double silicone oil film. This allows the substrate damage to be avoided during production, thus preventing it from affecting the adhesion of the polydimethylsiloxane coating, thereby effectively improving product quality while ensuring production efficiency.

[0041] A tension correction component 4 is provided. A spring-loaded clamping rod 416 and a support synchronization block 415 push the clamping and fixing roller 414 to move. The clamping and fixing roller 414 and the traction processing roller 408 clamp and hold the film. The traction electric slide rail 407 drives the traction processing roller 408 to move. Based on the discharge speed and the front-end processing speed, the tension and strength are adjusted to avoid tension, achieving film flattening and tension restriction during discharge, controlling the flatness of the actual discharged film. The tensioning electric slide rail 401 drives the tensioning slide block 402 to move. The tensioning slide block 402 and the guide tensioning roller 403 push the film to move, adjusting the surface tension of the film. To prevent the coated polydimethylsiloxane from sticking together, the film is suspended in mid-air and cured using a UV curing machine 335 to rapidly cure the polydimethylsiloxane on the film surface. A fixed-clamp roller 406 holds the film in place and applies low-temperature, slow-curing treatment. Through multi-position suspension support, tightness control, and synchronized curing, significant flow of the polydimethylsiloxane liquid is prevented during the coating process, and film folding and adhesion are avoided. This effectively prevents unevenness on the surface of the polydimethylsiloxane film, improving product quality.

[0042] In summary, by combining the pressure-removing component and the tension-correcting component, and through multi-segment tension restriction, tension adjustment, and tightness control, along with multi-position curing and coating thickness adjustment, control of multi-segment coating is achieved. Furthermore, by using multi-segment coating to gradually correct the coating, the uniformity of polydimethylsiloxane coating on the surface of the dual silicone film is ensured, thereby effectively improving product quality.
