Description

Technical Field

[0001] This invention belongs to the field of glass surface modification technology, specifically a method for preparing an environmentally friendly and wear-resistant coating that prevents impurities from precipitating out of glass bottles. Background Technology

[0002] Currently, some high-purity reagents on the market, such as high-purity chemicals for optics and electronics, high-purity chemicals for the metal-oxide-semiconductor electronics industry, and mass spectrometry-grade reagents, are highly sensitive to light and temperature, prone to aging, and even extremely small impurities can alter their properties. Therefore, their packaging and storage requirements are extremely stringent. Existing storage materials are typically 1-gallon (3.75-liter) amber glass bottles and 4-liter Nowpack plastic bottles (products of Intergol Corporation). However, Nowpack plastic bottles are made of high-density polyethylene, and their inner liner contains components prohibited by the EU environmental directives PFOS / PFOA. Glass, on the other hand, possesses excellent optical, mechanical, thermal, and chemical stability properties, making it a superior material for storing and packaging high-purity reagents.

[0003] Common surface treatment methods for glass storage bottles mainly include frosting (alkali removal) and siliconization. However, due to increasingly stringent requirements for ion release control, as well as specific requirements for the mechanical abrasion resistance and water resistance of both the inner and outer surfaces of glass storage bottles, traditional processes can no longer meet the requirements for the release of metal ions and other impurities from the inner surface of glass storage bottles, nor for the mechanical abrasion resistance and water resistance of the surface. Furthermore, the frosting process must be environmentally friendly. In addition, the inner surface treatment of glass storage bottles requires cleaning and drying, but existing drying equipment simply involves placing the glass bottles upside down in the drying equipment, resulting in slow removal of moisture from the glass bottles. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art; to this end, the present invention proposes a preparation method for preventing the precipitation of impurities in glass bottles and having an environmentally friendly wear-resistant coating.

[0008] Step 2: Clean the glass bottle and dry it using a drying device. Then, deposit a silicon dioxide film using a liquid phase method. The silicon dioxide film is deposited multiple times, from 1 to 6 times.

[0013] As a further aspect of the present invention: an installation plate is fixedly connected to the inner wall of the drying oven, and a connecting plate is fixedly connected to the horizontal plate.

[0014] As a further embodiment of the present invention: the shaking mechanism includes a motor fixedly connected to the mounting plate and a fixed frame fixedly connected to the inside of the drying oven. A cam that cooperates with the connecting plate is fixedly connected to the motor. A sliding groove is provided on one side of the fixed frame. The sliding groove is slidably connected to the horizontal plate. A spring is fixedly connected to the fixed frame. A receiving plate is fixedly connected to one end of the spring.

There are two racks. An adjustment component is disposed between the rack and the horizontal plate. A lifting component is disposed between the pressure plate and the horizontal plate.

[0016] As a further embodiment of the present invention: the adjustment assembly includes a fixed ring, a fixed shaft, and a fixed rod, which are respectively fixedly connected to the bottom of the horizontal plate. A toothed ring is rotatably connected to the bottom of the fixed ring. A gear that meshes with both the toothed ring and the rack is rotatably connected to the fixed shaft.

[0017] As a further aspect of the present invention: the fixing ring is located directly below the through hole, the rack is located below the toothed ring, and is slidably connected to the toothed ring.

[0018] As a further embodiment of the present invention: the lifting assembly includes a lead screw rotatably connected to the top of the horizontal plate and a vertical rod rotatably connected to the top of the horizontal plate.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The composite film prepared in this application possesses excellent environmental performance and mechanical wear resistance. Ferrous sulfate is used as a dealkalizing agent to initially remove alkali metal ions from the glass surface. The high-temperature decomposition of ferrous sulfate generates sulfur dioxide gas, which is removed by alkaline spraying. The choice of dealkalizing agent avoids nitrogen and phosphorus pollution, thus contributing to environmental protection. The acidic silica sol has a Si-O-Si network structure, resulting in a dense silica particle structure in the film, exhibiting good strength and quality. The protective layer coating not only protects the silica film but also provides certain mechanical wear resistance and water pressure resistance. This application employs a simple method with mild conditions, meets environmental requirements, improves the mechanical wear resistance of the film, and yields a relatively stable film quality, making it suitable for the deep processing of glass storage bottles, especially for storage bottles containing high-purity chemical reagents.

[0023] 2. In this application, when the glass bottle is placed in the through hole for drying, a shaking mechanism is used to drive the horizontal plate to shake back and forth, so that the glass bottle shakes and the water inside the glass bottle is discharged quickly, which is conducive to the rapid drying of the glass bottle.

[0024] 3. This application uses a clamping mechanism to hold and fix the glass bottles during the drying process, which can prevent the glass bottles from tipping over. At the same time, when clamping glass bottles with different bottle mouth sizes, the rotating toothed ring drives the rack to move, so that the rack contacts the edge of the bottle mouth. This facilitates the entry of hot air from the drying oven into the glass bottle and also facilitates the drainage of moisture from the glass bottle, avoiding moisture residue at the bottle mouth.

Detailed Implementation

[0031] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figures 1-4 As shown, this application provides a method for preparing an environmentally friendly and wear-resistant coating that prevents impurities from precipitating out of glass bottles, comprising the following steps:

[0034] Step 1: Use a 4L glass storage bottle, clean the bottle, add 60g of ferrous sulfate into the bottle, then heat to 500℃, keep it at that temperature for 20 minutes, and let it cool naturally.

[0035] Step 2: Deposit a silicon dioxide film using the liquid phase method.

[0036] The preparation process for depositing a silicon dioxide film is as follows:

[0037] 1) First, use high-pressure water to rinse, then place the glass bottle in an alkaline cleaning solution for ultrasonic cleaning. Use the alkaline cleaning solvent and 55°C water temperature for high-pressure water rinsing, then place it in an acidic cleaning solution for ultrasonic cleaning. Use the acidic cleaning solvent and 35°C water temperature for high-pressure water rinsing, and finally dry it for later use.

[0038] 2) The coating solution is acidic silica sol. After coating the glass bottle, it is heat-treated and dried at a low temperature of 100°C for a second coating. Then it is dried at a low temperature of 100°C again for 5 minutes each time. Finally, it is cured at a high temperature of 450°C for 10 minutes.

[0039] Step 3: A wear-resistant film layer is deposited on the silica film layer by high-pressure spraying. The coating amount of the wear-resistant film layer is 5 g / m2. The wear-resistant film layer slurry contains 93% hydrophilic aliphatic polyether polyurethane and 7% microporous agent. The microporous agent is nano-silica powder with a core-shell structure and a particle size of 35 nm. Then, it is dried. The drying is carried out in three temperature zones, with the temperature ranges of 80℃, 110℃, and 135℃, and the drying time of each zone is 8 minutes.

[0040] The drying equipment includes a drying box 1, a horizontal plate 2 is provided in the drying box 1, and a through hole 3 is provided on the top of the horizontal plate 2;

[0041] A shaking mechanism 4 is disposed between the horizontal plate 2 and the drying chamber 1. The shaking mechanism 4 is used to shake the glass bottle during drying to quickly drain the moisture from the inner wall of the glass bottle.

[0042] A clamping mechanism 5 is provided on the horizontal plate 2. The clamping mechanism 5 is used to clamp the glass bottle when it is shaken to prevent the glass bottle from tipping over.

[0043] An installation plate 6 is fixedly connected to the inner wall of the drying oven 1, and a connecting plate 7 is fixedly connected to the horizontal plate 2.

[0044] The shaking mechanism 4 includes a motor 41 fixedly connected to the mounting plate 6. The motor 41 is electrically connected to an external power source and controlled by an external control program. An isolation cover is provided outside the motor 41 to isolate the temperature inside the drying chamber 1. Alternatively, the motor 41 can be placed outside the drying chamber 1 during the initial design of the equipment, along with a fixed frame 42 fixedly connected inside the drying chamber 1. A cam 43 that cooperates with the connecting plate 7 is fixedly connected to the motor 41. A sliding groove 44 is provided on one side of the fixed frame 42, and the sliding groove 44 is slidably connected to the horizontal plate 2. A spring 45 is fixedly connected to the fixed frame 42, and a receiving plate 46 is fixedly connected to one end of the spring 45. The receiving plate 46 is fixedly connected to the horizontal plate 2. When the motor 41 is turned on, the cam 43 is driven to rotate. When the cam 43 rotates, it pushes the connecting plate 7 to move. At the same time, it works with the spring 45 to make the connecting plate 7 reciprocate, which in turn drives the horizontal plate 2 to reciprocate, so that the glass bottle is shaken, allowing the water inside the glass bottle to be discharged quickly, which is conducive to the rapid drying of the glass bottle.

[0045] Example 2

[0046] Based on Example 1, see Figures 1-4 As shown.

[0047] Step 1: Use a 4L glass storage bottle. First, clean the glass bottle, add 84g of ferrous sulfate into the bottle, then heat it to 550℃, keep it at that temperature for 30 minutes, and let it cool naturally.

[0048] Step 2: Deposit a silicon dioxide film using the liquid phase method.

[0049] The preparation process for depositing a silicon dioxide film is as follows:

[0050] 1) First, use high-pressure water to rinse, then place the glass bottle in an alkaline cleaning solution for ultrasonic cleaning. Use the alkaline cleaning solvent and 50°C water temperature for high-pressure water rinsing, then place it in an acidic cleaning solution for ultrasonic cleaning. Use the acidic cleaning solvent and 40°C water temperature for high-pressure water rinsing, and finally dry it for later use.

[0051] 2) The coating solution used is acidic silica sol. After coating the glass bottle, it is heat-treated, dried at a low temperature of 80°C, and then coated a second time. After drying at a low temperature of 80°C again, it is coated a third time. Finally, it is dried at a low temperature of 80°C for 15 minutes each time, and then cured at a high temperature of 500°C for 5 minutes.

[0052] Step 3: A wear-resistant film layer is deposited on the silica film layer by high-pressure spraying. The coating amount of the wear-resistant film layer is 8 g / m2. The wear-resistant film layer slurry contains 98% hydrophilic aliphatic polyether polyurethane and 2% microporous agent. The microporous agent is nano-silica powder with a core-shell structure and a particle size of 40 nm. Then, it is dried. The drying is carried out in three temperature zones, with the temperature ranges of 70℃, 100℃, and 140℃, and the drying time of each zone is 6 minutes.

[0053] The clamping mechanism 5 includes a rack 51 disposed at the bottom of the horizontal plate 2 and a pressure plate 52 disposed at the top of the horizontal plate 2. There are two racks 51. An adjustment component 53 is disposed between the rack 51 and the horizontal plate 2. A lifting component 54 is disposed between the pressure plate 52 and the horizontal plate 2.

[0054] The lifting assembly 54 includes a lead screw 541 rotatably connected to the top of the horizontal plate 2, and a vertical rod 542 rotatably connected to the top of the horizontal plate 2. The lead screw 541 is threadedly connected to the pressure plate 52, and the vertical rod 542 is slidably connected to the pressure plate 52. A rotating wheel 543 is fixedly connected to the outer surface of the lead screw 541.

[0055] The bottom of the pressure plate 52 is fixedly connected to a protruding rod 11, which is located directly above the through hole 3. Multiple protruding rods 11, through holes 3, and fixing rings 531 are provided, and the number is the same.

[0056] Example 3

[0057] Based on Example 1, see Figures 1-5 As shown.

[0058] Step 1: Use a 4L glass storage bottle. First, clean the glass bottle, add 100g of ferrous sulfate into the bottle, then heat it to 550℃, keep it at that temperature for 40 minutes, and let it cool naturally.

[0059] Step 2: Deposit a silicon dioxide film using the liquid phase method.

[0060] The preparation process for depositing a silicon dioxide film is as follows:

[0061] 1) First, use high-pressure water to rinse, then place the glass bottle in an alkaline cleaning solution for ultrasonic cleaning. Use the alkaline cleaning solvent and 50°C water temperature for high-pressure water rinsing, then place it in an acidic cleaning solution for ultrasonic cleaning. Use the acidic cleaning solvent and 40°C water temperature for high-pressure water rinsing, and finally dry it for later use.

[0062] 2) The coating solution used is acidic silica sol. After coating the glass bottle, it is heat-treated and dried at a low temperature of 90°C. The coating and drying are repeated 4 times, with each drying time being 8 minutes. Then, it is cured at a high temperature of 450°C for 10 minutes.

[0063] Step 3: A wear-resistant film layer is deposited on the silica film layer by high-pressure spraying. The coating amount of the wear-resistant film layer is 5 g / m2. The wear-resistant film layer slurry contains 95% hydrophilic aliphatic polyether polyurethane and 5% microporous agent. The microporous agent is nano-silica powder with a core-shell structure and a particle size of 45 nm. Then, it is dried. The drying is carried out in three temperature zones, with the temperature ranges of 90℃, 120℃, and 145℃, and the drying time of each temperature zone is 4 min.

[0064] The adjustment assembly 53 includes a fixed ring 531, a fixed shaft 532, and a fixed rod 533, which are fixedly connected to the bottom of the horizontal plate 2. A toothed ring 534 is rotatably connected to the bottom of the fixed ring 531. There is a damping effect between the fixed ring 531 and the toothed ring 534. Without external force, the toothed ring 534 will not rotate on the fixed ring 531. A gear 535 that meshes with both the toothed ring 534 and the rack 51 is rotatably connected to the fixed shaft 532. A support plate 536 is fixedly connected to the bottom of the fixed rod 533. The support plate 536 has a limit groove 537, and the rack 51 is slidably connected in the limit groove 537. The glass bottle to be dried is placed upside down in the through hole 3. Then, rotating the rotating wheel 543 drives the lead screw 541. Under the limiting action of the upright rod 542, the lifting component 54 is lowered, so that the protruding rod 11 presses against the bottom of the glass bottle. The glass bottle is clamped and fixed by the cooperation of the protruding rod 11 and the rack 51. Then, when clamping glass bottles with different bottle mouth sizes, rotating the gear ring 534 drives the gear 535 to rotate through the meshing transmission. Through the meshing transmission and the limiting action of the limiting groove 537, the rack 51 is moved in the limiting groove 537, so that one end of the rack 51 contacts the edge of the bottle mouth. In this way, when the water in the glass bottle is discharged, it will not flow onto the rack 51, avoiding water residue at the bottle mouth. And the bottle mouth is in an open state, which is conducive to the hot air in the drying oven 1 entering the glass bottle to dry it.

[0065] The fixing ring 531 is located directly below the through hole 3, and the rack 51 is located below the toothed ring 534 and is slidably connected to the toothed ring 534.

[0066] Connecting arms 8 are fixedly connected to both sides of the outer surface of the fixing ring 531, and an mounting ring 9 is fixedly connected between the two connecting arms 8. A collecting cylinder 10 is threaded onto the mounting ring 9. When drying the glass bottle, the water discharged from the glass bottle will fall into the collecting cylinder 10 for collection. After drying the glass bottle for a period of time, the glass bottle is taken out, and at the same time, the collecting cylinder 10 is removed from the mounting ring 9, and the water is poured out.

[0067] Example: Mechanical abrasion resistance and water pressure resistance of the film layer after testing

[0068]

[0069] The working principle of this invention is as follows: Open the chamber door and place the glass bottle to be dried upside down in the through hole 3. Then, rotate the rotating wheel 543 to drive the lead screw 541. Under the limiting action of the upright rod 542, the lifting assembly 54 is lowered, causing the protruding rod 11 to press against the bottom of the glass bottle. The glass bottle is clamped and fixed through the cooperation of the protruding rod 11 and the rack 51. When clamping glass bottles with different mouth sizes, rotating the gear ring 534 causes the gear 535 to rotate through meshing transmission. Through meshing transmission and the limiting action of the limiting groove 537, the rack 51 moves within the limiting groove 537, so that one end of the rack 51 contacts the edge of the bottle mouth. This prevents water from flowing onto the rack 51 when the glass bottle is drained, avoiding water residue at the bottle mouth. Furthermore, the open bottle mouth allows hot air from the drying chamber 1 to enter the glass bottle for drying. Next, close the cabinet door and turn on the motor 41, which in turn drives the cam 43 to rotate. As the cam 43 rotates, it pushes the connecting plate 7 to move, working in conjunction with the spring 45 to cause the connecting plate 7 to reciprocate. This, in turn, drives the horizontal plate 2 to reciprocate, causing the glass bottle to shake and allowing the water inside to drain quickly, thus facilitating rapid drying. The water drained from the glass bottle then falls into the collecting cylinder 10 for collection. After the glass bottle has been dried for a period of time, remove it from the cabinet, detach the collecting cylinder 10 from the mounting ring 9, and pour out the water.

[0070] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
