Description

Technical Field

[0001] The invention relates to the technical field of resin production, in particular to a reaction kettle for producing alkali-resistant modified resin and a production method. Background Art

[0002] Optical resins are high-performance materials specifically designed for optical applications, exhibiting excellent optical and mechanical properties. They are commonly used in the manufacture of optical components such as lenses, prisms, and filters, as well as in fiber optic communications, medical devices, and photographic equipment. A variety of methods are used for their preparation. Polymerization is one of the most commonly used methods for preparing optical resins. This involves forming polymer chains through covalent bonds between monomer molecules. Polymerization reactions typically require an appropriate solvent or reaction medium, with the addition of an initiator to initiate the reaction. Adjusting parameters such as monomer type, reaction conditions, and molecular weight can control the properties and uses of the resin. Commonly used polymerization methods in industry include bulk polymerization, suspension polymerization, emulsion polymerization, solution polymerization, slurry polymerization, and gas-phase polymerization. Suspension polymerization involves the polymerization of monomers in a suspension of water, often dispersed into droplets, under mechanical stirring or oscillation and the presence of a dispersant. This process is also known as bead polymerization. Traditional reactors used to synthesize optical resins typically heat the resin and other chemical raw materials through the reactor walls, and stir and mix the raw materials using a stirring blade located in the center of the reactor.

[0003] In this regard, China has filed patent application number CN117380137A, which discloses a resin reactor and its use method. The reactor chamber is equipped with multiple heating cylinders, and a first drive member is used to rotate the multiple heating cylinders. A first gear ring is coaxially disposed on the inner circumference of the reactor body. The first gear ring is rotatably connected to multiple guide rods, which are rotatably connected to the heating cylinders. The guide rods engage with a second gear ring via a direction-adjusting gear. A second drive member is used to rotate a transmission gear. The second gear can engage with the second gear ring, and the first gear can engage with the first gear ring. A third drive member is used to drive the transmission gear to move vertically. An adjustment member can push the fan blades to extend from the heating cylinders. A resistance plate is provided at the bottom of the heating cylinders. The resistance plate is rotatably connected to the third gear via a rotating shaft. The rack is fixedly connected to the adjustment member. This resin reactor and its use method improve the heating efficiency of the reaction materials, increase the reaction rate, and achieve automatic cleaning of the fan blades.

[0004] However, when the reactor and production method for producing the alkali-resistant modified resin are in use, since the resin needs to be mixed during the production process, resin solution may remain on the inner wall of the reactor during the mixing process. The existing device is unable to clean the residual material on the inner wall of the reactor after use, which to a certain extent affects the normal operation of the device next time.
