Description

Technical Field

[0001] This application relates to the field of silicone resin synthesis technology, and more specifically to a pressure and temperature adjustable synthesis apparatus for the production of organosilicon resin. Background Technology

[0002] Silicone resins are a class of polymeric compounds with polysiloxane as the main chain structure and alternating organic groups and silicon-oxygen bonds (Si–O–Si) in their molecules. They are typical organic-inorganic hybrid materials. Due to their highly cross-linked molecular structure, silicone resins combine the flexibility of organic resins with the stability of inorganic materials. They possess excellent properties such as high temperature resistance, cold resistance, weather resistance, strong electrical insulation, hydrophobic surface, and anti-sticking and mold-release properties. Therefore, they are widely used in many fields such as electronics, aerospace, automotive industry, architectural coatings, and mold manufacturing.

[0003] In the production of silicone resins, the siloxane chain structure is typically constructed through reactions such as hydrolytic condensation or cyclic ring-opening polymerization, and further cross-linking forms a thermosetting network structure. This process places extremely high demands on the stability of the reaction environment, especially the pressure and temperature control within the reaction chamber. Reaction pressure and temperature are key factors affecting the reaction rate, degree of condensation, and the performance of the final product.

[0004] However, existing silicone resin synthesis equipment typically lacks efficient and precise pressure and temperature control mechanisms, making it difficult to monitor and regulate changes in key parameters during the reaction process in real time. On the one hand, improper pressure control may lead to gas escape from the reaction chamber or uneven distribution of reactants, thus affecting the uniformity of the reaction and the molecular structure of the product. On the other hand, imprecise temperature control can cause the reaction rate to be too slow or the reaction to overheat, affecting the yield and quality of the silicone resin. Utility Model Content

[0021] To make the content of this application easier to understand, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to the accompanying drawings. Figure 3 In the context of direction, the terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0022] like Figures 1-3 As shown, a pressure- and temperature-adjustable synthesis apparatus for producing organosilicon resin includes a vessel body 1, a cover body 2, a stirring assembly 3, a feed pipe 4, a pressure pump 5, an electronic pressure gauge 6, a pressure relief pipe 7, a jacket 8, an inner disc heating element 9, a temperature controller 10, and a temperature sensor 11. The vessel body 1 has a cylindrical structure, with a support leg 16 fixedly installed at the bottom. The bottom of the vessel body 1 is closed, and its top is open. The top opening of the vessel body 1 is fixedly and sealed to the cover body 2. The feed pipe 4 is fixedly installed on the cover body 2 and communicates with the interior of the vessel body 1. An observation window 15 is fixedly and sealed at the top of the feed pipe 4. The pressure pump 5 is fixedly installed on the cover body 2, and the outlet pipe of the pressure pump 5 communicates with the interior of the vessel body 1. An electronic pressure gauge 6 is fixedly installed on the cover body 2. The probe extends into the interior of the reactor body 1. A pressure relief pipe 7 is fixedly installed on the cover 2, and the pressure relief pipe 7 is connected to the interior of the reactor body 1 and a pressure relief solenoid valve 12 is fixedly installed on it. An electronic pressure gauge 6 is electrically connected to the pressurizing pump 5 and the pressure relief solenoid valve 12 respectively. In the above design, by setting up the pressurizing pump 5, the electronic pressure gauge 6 and the pressure relief pipe 7, the pressure inside the synthesis reactor can be monitored and precisely controlled in real time. The electronic pressure gauge 6 monitors the pressure inside the reactor in real time and feeds the data back to the pressurizing pump 5 and the pressure relief solenoid valve 12. When the pressure is insufficient, the pressurizing pump 5 automatically starts to replenish gas into the reactor to ensure that the pressure inside the reactor is stable. When the pressure is too high, the pressure relief solenoid valve 12 opens quickly and releases excess gas through the pressure relief pipe 7 to prevent gas from escaping from the synthesis reactor or uneven distribution of the synthesized product, thus effectively improving product quality.

[0023] A jacket 8 is fixedly installed circumferentially on the outer wall of the vessel body 1. A hollow cavity is formed between the inner wall of the jacket 8 and the outer wall of the vessel body 1. An inner disc heating tube 9 is installed in the hollow cavity and is in contact with the outer wall of the vessel body 1. A temperature controller 10 is fixedly installed on the outer wall of the jacket 8. Several temperature sensors 11 are fixedly installed circumferentially on the side wall of the jacket 8. The temperature sensors 11 are distributed in two layers along the axial direction of the vessel body 1, with four temperature sensors 11 in each layer. The four temperature sensors 11 in each layer are equidistant from each other circumferentially on the vessel body 1. The distance between the two layers of temperature sensors 11 is half the internal height of the vessel body 1. The probe of each temperature sensor 11 extends into the interior of the vessel body 1. The temperature controller 10 is electrically connected to the temperature sensor 11 and the inner disc heating tube 9. In the above design, the temperature control system composed of the jacket 8, the inner disc heating tube 9, the temperature controller 10, and the temperature sensor 11 can efficiently and accurately regulate the synthesis temperature. The multi-layer temperature sensors 11 distributed along the circumference and axis of the reactor body 1 can monitor the temperature changes at different locations inside the reactor in real time and transmit the data to the temperature controller 10. The temperature controller 10 intelligently adjusts the power of the inner disc heating tube 9 according to the difference between the set temperature and the actual monitored temperature to ensure that the temperature inside the reactor is always maintained within the set range, avoiding slow synthesis rate or overheating inside the reactor due to imprecise temperature control, thereby improving the synthesis efficiency and quality of silicone resin.

[0024] A stirring assembly 3 is fixedly installed on the cover 2. The stirring assembly 3 includes a drive motor 31, a stirring shaft 32, frame-type stirring blades 33, axial flow blades 34, and a spiral stirring paddle 35. The drive motor 31 is fixedly installed at the center of the top of the cover 2. The output shaft of the drive motor 31 passes through the top of the cover 2 and is fixedly connected to the upper end of the stirring shaft 32. The stirring shaft 32 extends axially along the vessel body 1, and its lower end is located above the bottom of the vessel body 1. The axis of the stirring shaft 32 coincides with the axis of the vessel body 1. A frame-type stirring blade 33, an axial flow blade 34, and a spiral stirring paddle 35 are fixedly mounted sequentially from top to bottom along the axial direction of the shaft 32. The upper end of the frame-type stirring blade 33 is fixedly connected to the upper part of the stirring shaft 32, while its lower end is not connected. The outer shape of the frame-type stirring blade 33 is adapted to the inner wall of the vessel body 1, and the two slide in contact. A relief groove 331 is recessed inward on the frame-type stirring blade 33 at the height corresponding to the installation of the temperature sensor 11, so that the frame-type stirring blade 33 can rotate to avoid the temperature sensor. To avoid interference between the two, the axial flow blades 34 and the spiral impeller 35 are arranged horizontally along the axial direction of the stirring shaft 32, with the lower end of the spiral impeller 35 positioned above the bottom of the frame-type stirring blades 33. In the above design, the combined design of the frame-type stirring blades 33, axial flow blades 34, and spiral impeller 35 in the stirring assembly 3 greatly optimizes the stirring effect of the synthesized materials. The outer side of the frame-type stirring blades 33 slides in contact with the inner wall of the vessel body 1, which can effectively scrape off the material adhering to the vessel wall and prevent the material from sticking to the wall. The horizontal arrangement of the axial flow blades 34 enables the material to be fully mixed in the horizontal direction. The spiral impeller 35 promotes the axial flow of the material. The three stirring components work together to achieve full mixing of the material in all directions and at multiple angles in the vessel, improving the uniformity and efficiency of the synthesis. At the same time, the avoidance groove 331 design on the frame-type stirring blades 33 cleverly avoids interference with the temperature sensor 11 probe, ensuring the normal operation of the stirring assembly 3 and the temperature monitoring system.

[0025] A discharge pipe 13 is fixedly provided at the bottom of the vessel body 1. The discharge pipe 13 is set off from the center of the bottom of the vessel body 1. This design allows the opening of the discharge pipe 13 to avoid the rotation axis of the frame-type stirring blade 33, so as to facilitate smooth discharge. A discharge control valve 14 is provided on the discharge pipe 13. In this design, the discharge pipe 13 is set off from the center of the bottom of the vessel body 1, which effectively avoids the rotation axis of the frame-type stirring blade 33, making the discharge process smoother, avoiding the obstruction of the stirring blade and the resulting poor discharge or residue, improving production efficiency, reducing material waste, and facilitating the collection and processing of subsequent products.
