Description

Technical Field

[0001] This invention belongs to the field of bathroom product manufacturing technology, specifically a composition of unsaturated resin and xylene and its preparation method. Background Technology

[0002] With the continuous improvement of modern living standards, the production quality and functionality of bathroom products are also constantly being improved, and the derivative types of bathroom products are also becoming increasingly diverse, such as toothbrush holders, shower gel bottles, and so on. Considering the usage environment and requirements of these bathroom derivative products, most bathroom derivative products on the market are currently made by mixing unsaturated resin and propylene. Products made by mixing unsaturated resin and propylene have good corrosion resistance, rigidity, and strength, which greatly meets the usage requirements of the bathroom environment.

[0003] In existing technologies, the high unit cost of fusing unsaturated resin and propylene increases the manufacturing cost of the product, failing to meet market demands. Therefore, improvements have been made by replacing propylene with xylene. The product can be obtained by mixing unsaturated resin, xylene, and stone powder in a certain proportion and then vacuum degassing. This preparation method has a lower unit cost. However, the product after mixing unsaturated resin and xylene has a high viscosity. The addition of stone powder, due to its particle nature, further increases the viscosity of the mixture. This results in some residual mixture adhering to the inner wall of the device after vacuum degassing, which is difficult to remove and leads to waste. Moreover, the inner wall of the device needs to be cleaned by workers later, increasing the workload.

[0004] Therefore, the present invention provides a composition of unsaturated resin and xylene and a method for preparing the same. Summary of the Invention

[0005] To address the shortcomings of existing technologies and solve the problem that the high unit cost of fusing unsaturated resin and propylene in existing technologies increases the manufacturing cost of products and fails to meet market demands, this invention proposes an improvement. By replacing propylene with xylene, unsaturated resin, xylene, and stone powder are mixed in a certain proportion and then vacuum degassed to obtain the product. This preparation method has a lower unit cost. However, the product of unsaturated resin and xylene has a high viscosity. Adding stone powder further increases the viscosity due to its particulate nature. This results in some residual mixture adhering to the inner wall of the device after vacuum degassed, making it difficult to remove and causing waste. Furthermore, it requires subsequent cleaning of the inner wall of the device, increasing workload. Therefore, this invention proposes a composition of unsaturated resin and xylene and its preparation method.

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] like Figures 1-13 As shown in the embodiment of the present invention, a method for preparing a composition of unsaturated resin and xylene is provided, the preparation method comprising the following steps:

[0039] S1: Weigh out unsaturated resin, xylene and stone powder in a certain proportion. Put the unsaturated resin and xylene into a vacuum degassing device and stir to mix. Then add stone powder and stir slowly.

[0040] S2: After mixing stone powder with unsaturated resin and xylene in a vacuum degassing machine, add 3% hardener and 0.3% catalyst to the new mixture. After stirring evenly, perform vacuum degassing, then grouting, and demolding after 30 minutes.

[0041] S3: After demolding, the product is ground, soaked in alkali, machine-sanded, repaired, covered with glass, sprayed with oil, and painted to complete the latest resin product formula.

[0042] The vacuum degassing device in S1 includes a body 1. A feed inlet 2 is fixedly connected to the top of the body 1, and a discharge outlet 3 is fixedly connected to the bottom of the body 1. Fixing plates 28 are fixedly connected to both sides of the inner cavity of the body 1. A rotating shaft 13 is rotatably connected to the fixing plate 28. One end of the rotating shaft 13 extends to the outside of the body 1 and is fixedly connected to the output end of a motor 4. The motor 4 is fixedly installed on the outer wall of the body 1. Two spiral stirring plates 14 are symmetrically sleeved on the rotating shaft 13. Elastic stirring components are provided at both ends of the rotating shaft 13. A scraper 18 is fixedly connected to the side of the elastic stirring component away from the rotating shaft 13. The scraper 18 is in contact with the inner wall of the body 1 and is equipped with a cleaning component. During operation, the operator first feeds unsaturated resin, xylene, and stone powder through the feed inlet 2. The mixture is then placed into the inner cavity of the machine body 1. The spiral stirring plate 14 and the elastic stirring component on the rotating shaft 13 driven by the motor 4 can stir the mixture evenly. After the mixture is stirred and vacuum degassed, it can be discharged from the discharge port 3. However, because the mixture of unsaturated resin and xylene is relatively viscous, it is easy to adhere to the arc-shaped inner wall of the machine body 1, resulting in incomplete discharge. At this time, the elastic stirring component on the rotating shaft 13 can be rotated by the motor 4, so that the scraper 18 can scrape the mixture adhering to the inner wall of the machine body 1. With the help of the cleaning component, the adhering mixture can be concentrated to the discharge port 3 and finally discharged from the discharge port 3, achieving complete discharge. This not only avoids the problem that traditional vacuum degassing devices cannot completely discharge the mixture after stirring, but also cleans the inner wall of the machine body 1.

[0043] The elastic stirring assembly includes a stirring rod 15, a spring 16, and a support rod 17. One end of the stirring rod 15 is fixedly connected to the rotating shaft 13. The support rod 17 is slidably connected within the inner cavity of the stirring rod 15. A spring 16 is fixedly connected between one end of the support rod 17 and the inner wall of the stirring rod 15. The other end of the support rod 17 extends to the outside of the stirring rod 15 and is fixedly connected to the scraper 18. A limiting component is provided between the support rod 17 and the mounting plate. During operation, when discharge begins, the stirring rod 15 is driven by the motor 4. The downward movement drives the support rod 17 and scraper 18 to rotate, scraping the residual mixture on the inner wall of the machine body 1. When the support rod 17 rotates once and approaches the discharge port 3 below, the limiting component allows the support rod 17 to drive the scraper 18 to slide upward, so that the mixture scraped by each rotation can be concentrated near the discharge port 3, preventing it from being scraped away by the scraper 18 and misaligned with the discharge port 3. After sliding past the discharge port 3, the elastic force of the spring 16 allows the scraper 18 to stick to the inner wall of the machine body 1 again.

[0044] The limiting assembly includes a connecting rod 19 and a limiting block 20. The connecting rod 19 is fixedly connected to the support rod 17, and the limiting block 20 is fixedly connected to the other end of the connecting rod 19. A limiting groove 29 is provided on the mounting plate. The limiting block 20 is slidably connected to the limiting groove 29. The limiting groove 29 is composed of an arc-shaped groove and an arched groove. The arched groove is adapted to the discharge port 3. During operation, when the limiting block 20 slides in the arc-shaped groove, the scraper 18 can scrape the residual mixture attached to the inner wall of the machine body 1. When the limiting block 20 slides in the arched groove, the scraper 18 will first slide upward, then slide smoothly, and finally slide downward again. During this process, the scraper 18 is no longer in contact with the inner wall of the machine body 1, which can concentrate the scraped residue near the discharge port 3.

[0045] The cleaning assembly includes a fixed sleeve 21, a support rod 23, and a cleaning plate 26. The fixed sleeve 21 is fixedly connected to the scraper 18. The support rod 23 is slidably connected to the inner cavity of the fixed sleeve 21. One end of the support rod 23 extends to the outer side of the fixed sleeve 21 and is fixedly connected to a slider 24. A spring 22 is fixedly connected between the support rod 23 and the inner wall of the fixed sleeve 21. The slider 24 is slidably connected to the scraper 18. A guide block 25 is fixedly connected to the inner side of the slider 24. A guide groove 30 and a guide groove 31 are symmetrically formed on the arc-shaped inner wall of the machine body 1, and the guide grooves 30 and 31 are connected. The guide block 25 is slidably connected to the guide grooves 30 and 31. The slider 24 is fixedly connected to the cleaning plate 26, and the cleaning plate 26 is in contact with the surface of the scraper 18. During operation, when… The guide block 25 slides within the first guide groove 30. The cleaning plate 26 is located at one end of the scraper 18. When the guide block 25 slides into the second guide groove 31, it drives the slider 24 to slide upwards on the scraper 18. At the same time, the cleaning plate 26 cleans the mixture adhering to the scraper 18 during the scraping process. Until the guide block 25 slides to the end of the second guide groove 31, the second spring 22 is in a compressed state. The limiting block 20 slides into the arched groove, driving the scraper 18 to slide upwards, causing the guide block 25 to disengage from the second guide groove 31. The elastic force of the second spring 22 causes the support rod 23 to reset the cleaning plate 26. When the limiting block 20 slides into the arc-shaped groove again, the guide block 25 slides into the first guide groove 30, realizing cyclical rotation cleaning and preventing residual mixture from adhering to the surface of the scraper 18 and affecting the scraping effect of the scraper 18.

[0046] The first guide groove 30 is arc-shaped, and the second guide groove 31 is inclined. Both the first guide groove 30 and the second guide groove 31 are adapted to the discharge port 3. An arc-shaped plate 27 is fixed to the side of the cleaning plate 26 away from the scraper 18. The arc-shaped plate 27 is in contact with the fixed plate 28 and the arc-shaped inner wall of the machine body 1. During operation, when the guide block 25 slides in the second guide groove 31, the arc-shaped plate 27 can push the mixture concentrated at the bottom of the inner cavity of the machine body 1 towards the discharge port 3 during rotation, facilitating the rapid discharge of the mixture. During the mixing process, the arc-shaped plate 27... The rotary stirring of 7 can avoid the problem of uneven mixing caused by the difficulty of stirring at the corners in the use of traditional vacuum degassing devices. During stirring, the two symmetrically arranged spiral stirring plates 14 can push the middle mixture to both sides. In addition, the arc plate 27 slides to the discharge port 3 along with the cleaning plate 26 and then resets in a cycle. This makes the mixture in the inner cavity of the machine body 1 present a reciprocating flow process from the middle to both sides and then from both sides to the middle. This can improve the mixing effect and avoid the accumulation of materials at the bottom of the inner cavity of the machine body 1, resulting in local sedimentation.

[0047] Two feed pipes 5 are symmetrically fixed to both sides of the top of the feed inlet 2. A hopper 6 is fixed to the inner cavity of the feed inlet 2. A feed pipe 7 and an air pump 8 are fixed to the top of the hopper 6. A discharge pipe is fixed to the bottom of the hopper 6. Valves are installed on the feed pipes 5, 7, and discharge pipe. A guide plate 9 is fixed to the upper part of the inner cavity of the machine body 1. The guide plate 9 is compatible with the discharge pipe. During operation, the unsaturated resin can be discharged through the two feed pipes 5 on the feed inlet 2. First, xylene and other substances are added to the inner cavity of the machine body 1. After they are mixed evenly, the stone powder is fed into the hopper 6 through the feed pipe 2 7. The stone powder is then blown into the inner cavity of the machine body 1 by the air pump 8. The blown stone powder is quickly dispersed to all four parts of the inner cavity of the machine body 1 by the guide plate 9 provided above the inner cavity of the machine body 1. This facilitates the even mixing of stone powder with the unsaturated resin and xylene, and avoids the stone powder from being unable to quickly enter the mixture due to the high viscosity of the mixture.

[0048] The guide plate 9 has a first guide groove 10 and a second guide groove 11, which are fishbone shaped and have uniformly distributed through holes. The guide plate 9 gradually narrows from the middle to both sides, and multiple sets of baffles 12 are fixed to the guide plate 9. The baffles 12 are adapted to the first guide groove 10 and the second guide groove 11. During operation, the stone powder can be directly fed into the first guide groove 10 after being blown out of the feed hopper 6 by the guide grooves 10 and 11 and the baffles 12. It can also be dispersed into the second guide groove 11 along the first guide groove 10. The shape design of the guide plate 9 allows the stone powder to be quickly dispersed to all parts of the inner cavity of the machine body 1, achieving rapid and uniform mixing.

[0049] Both sides of the guide plate 9 are inlaid with fixing sleeves 32. An annular plate 33 is slidably connected to the inner cavity of each fixing sleeve 32. A sliding rod 34 is sleeved on the annular plate 33. The top end of the sliding rod 34 extends above the fixing sleeve 32 and is fixedly connected to a hemispherical body 35, which is adapted to the scraper 18. The bottom end of the sliding rod 34 extends below the fixing sleeve 32 and is fixedly connected to a support plate 36. Vibration blocks 38 are evenly fixed on the support plate 36, and the vibration blocks 38 are in contact with the bottom of the guide plate 9. The annular plate 33 and the fixing sleeve... A spring 37 is fixedly connected between the inner walls of cylinder 2 32. During operation, when scraper 18 rotates above hemispherical body 35, scraper 18 will squeeze hemispherical body 35, causing slide rod 34 to drive annular plate 33 to compress spring 37. At the same time, support plate 36 drives vibrating block 38 away from guide plate 9. After scraper 18 moves away from hemispherical body 35, the elastic force of spring 37 causes support plate 36 to drive vibrating block 38 to quickly reset and strike the bottom of guide plate 9, causing guide plate 9 to vibrate. This can accelerate the dispersion of stone powder and prevent stone powder from clogging the through hole.

[0050] A composition comprising unsaturated resin and xylene, wherein the composition is prepared by the method for preparing a composition comprising unsaturated resin and xylene as described in claim 1, the composition comprising 34% unsaturated resin, 45% xylene and 21% stone powder.

[0051] Working principle: The operator feeds unsaturated resin, xylene, and stone powder into the inner cavity of the machine body 1 through the feed inlet 2. The motor 4 drives the spiral stirring plate 14 and elastic stirring component on the rotating shaft 13 to stir the mixture evenly. After stirring and vacuum degassing, the mixture is discharged from the outlet 3. Because the mixture of unsaturated resin and xylene is quite viscous, it easily adheres to the arc-shaped inner wall of the machine body 1, causing incomplete discharge. At this point, the motor 4 drives the elastic stirring component on the rotating shaft 13 to rotate, allowing the scraper 18 to scrape the mixture adhering to the inner wall of the machine body 1. Combined with the cleaning component, the adhering mixture is concentrated at the outlet 3 and finally discharged from the outlet 3, achieving complete discharge and avoiding [missing information - likely a continuation of the process]. This design avoids the problem of incomplete material discharge after mixing, which is common with traditional vacuum degassing devices. It also cleans the inner wall of the machine body 1. When discharge begins, the stirring rod 15, driven by the motor 4, rotates the support rod 17 and scraper 18 to scrape away any remaining mixture on the inner wall of the machine body 1. As the support rod 17 rotates once and approaches the discharge port 3 below, the limiting component allows the support rod 17 to slide the scraper 18 upwards. This concentrates the scraped mixture near the discharge port 3, preventing it from being scraped away again and misaligned with the discharge port 3. After passing the discharge port 3, the spring force of the spring 16 allows the scraper 18 to re-adhere to the inner wall of the machine body 1. When the limiting block 20 slides within the arc-shaped groove, the scraper 1... 8 can scrape the residual mixture adhering to the inner wall of the machine body 1. When the limiting block 20 slides in the arched groove, the scraper 18 will first slide upward, then smooth down, and finally slide downward again. During this process, the scraper 18 is no longer in contact with the inner wall of the machine body 1, which can concentrate the scraped residue near the discharge port 3. When the guide block 25 slides in the first guide groove 30, the cleaning plate 26 is located at the end of one side of the scraper 18. When the guide block 25 slides into the second guide groove 31, the guide block 25 will drive the slider 24 to slide upward on the scraper 18. At the same time, the cleaning plate 26 can clean the mixture adhering to the scraper 18 during the scraping process, until the guide block 25 slides to the end of the second guide groove 31. At this time, the second spring 22 is in a compressed state, and the limiting block 20 slides into the arched groove to drive the scraper. Sliding 18 causes guide block 25 to disengage from guide groove 31. The spring force of spring 22 causes support rod 23 to reset cleaning plate 26. When limit block 20 slides back into arc groove, guide block 25 slides into guide groove 30, achieving cyclical rotational cleaning. This prevents residual mixture from adhering to the surface of scraper 18 and affecting its cleaning effect. When guide block 25 slides in guide groove 31, arc plate 27 can push the mixture concentrated at the bottom of the machine body 1 towards discharge port 3 during rotation, facilitating rapid discharge. Furthermore, during mixing, the rotation of arc plate 27 avoids the problem of uneven mixing caused by difficulty in mixing at the corners, which is common in traditional vacuum degassing devices.Two symmetrically arranged spiral stirring plates 14 push the mixture in the middle to both sides. Combined with the arc-shaped plate 27 sliding towards the discharge port 3 along with the cleaning plate 26 and then resetting in a cyclical process, the mixture inside the machine body 1 exhibits a reciprocating flow from the center to both sides and then from both sides back to the center. This improves the mixing effect and prevents material accumulation at the bottom of the machine body 1, thus avoiding localized sedimentation. Unsaturated resin and xylene are first added to the machine body 1 through two feed pipes 5 on the feed inlet 2. After they are evenly mixed, stone powder is fed into the hopper 6 through the feed pipe 7, and then blown into the machine body 1 through the air pump 8. The blown stone powder is quickly dispersed throughout the machine body 1 by the guide plate 9 located above the machine body 1, facilitating even mixing of the stone powder with the unsaturated resin and xylene and preventing the mixture from becoming viscous due to its high viscosity. The high flowability results in poor flowability, preventing stone powder from quickly entering the mixture. By using guide channel 10 and guide channel 21 in conjunction with baffle 12, stone powder can be blown directly from the hopper 6 into guide channel 10 and dispersed along guide channel 10 into guide channel 21. The shape design of guide plate 9 allows stone powder to be quickly dispersed throughout the inner cavity of machine body 1, achieving rapid and uniform mixing. When scraper 18 rotates above hemispherical body 35, scraper 18 will squeeze hemispherical body 35, causing slide rod 34 to drive annular plate 33 to compress spring 37. At the same time, support plate 36 drives vibrating block 38 away from guide plate 9. After scraper 18 moves away from hemispherical body 35, the elastic force of spring 37 causes support plate 36 to drive vibrating block 38 to quickly reset and strike the bottom of guide plate 9, causing guide plate 9 to vibrate. This can accelerate the dispersion of stone powder and prevent stone powder from clogging the through hole. ,
