Description

Technical Field

[0001] This utility model belongs to the field of UV adhesive reaction synthesis equipment, specifically a UV adhesive reaction synthesis device. Background Technology

[0002] With the widespread application of photocuring technology, UV adhesives, as a fast-curing, environmentally friendly and efficient bonding material, have developed rapidly in many fields such as electronics, optics, automobiles, and medical. During the preparation of UV adhesives, the raw materials are extremely sensitive to ultraviolet light. Therefore, it is necessary to strictly avoid light during the synthesis stage to prevent premature curing and affect product quality. At the same time, the synthesis of UV adhesives usually requires reaction under certain temperature conditions to promote cross-linking and polymerization between raw material molecules. This places dual requirements on experimental equipment, which must control the temperature and avoid light.

[0003] Currently, double-walled glass reactors are widely used in the field of adhesive synthesis. Their core advantages include the use of high borosilicate glass for the reactor body, which has excellent chemical stability and can withstand corrosive raw materials such as epoxy adhesives and silicone adhesives. Furthermore, the reaction temperature can be dynamically adjusted by circulating heat transfer oil or refrigerant in the jacket, meeting the synthesis requirements of temperature-sensitive materials such as hot melt adhesives. Although the above equipment is suitable for conventional adhesive synthesis, UV-curable adhesives (such as photocurable acrylic adhesives) require ultraviolet light to initiate polymerization. However, in existing technologies, the materials need to be transferred to a separate UV irradiation device after the reaction is completed, which reduces production efficiency. Moreover, the transfer process is prone to introducing impurities or initiating prepolymerization, thus causing inconvenience to the preparation of UV adhesives.

[0004] In summary, this invention provides a UV adhesive reaction synthesis device to solve the above problems. Utility Model Content

[0022] Example 1

[0023] like Figure 1-4 The first embodiment of this utility model is shown, which provides a UV glue reaction synthesis device, including a sealed cabinet 100, including a cabinet body 110 and a cabinet door 120 located on the front of the cabinet body 110; a reaction vessel 200, including a vessel body 210 for providing reaction space, a top cover 220 located on the top of the vessel body 210, and an interface 230 located on the top of the top cover 220, and the reaction vessel 200 is installed in the inner cavity of the cabinet body 110; a stirring assembly 300, including a stirring shaft 310, stirring blades 320 fixed to the surface of the stirring shaft 310, a drive motor 330 located on the top of the top cover 220, a reducer 340 and a support base 350; and a frequency converter 360 fixed to the surface of the cabinet door 120, and the output end of the frequency converter 360 is electrically connected to the drive motor 330; and a UV lamp 400, fixed to one side of the cabinet body 110 and penetrating into the inner cavity of the cabinet body 110.

[0024] like Figure 1-4As shown, the UV lamp 400 is preferably an LED ultraviolet lamp, which has the advantages of energy saving, environmental protection, and long life. The irradiation intensity of the UV lamp 400 can be adjusted by an external controller to meet the ultraviolet requirements in different UV adhesive synthesis processes. The reactor 200 is made of transparent glass, and the constant temperature water bath 500 contains a heat-conducting medium, which can be heat-conducting oil or water. The temperature of the heat-conducting medium is controlled by heating. The heat-conducting medium circulates in the jacket 213 to achieve uniform heating or cooling of the reactor 200, ensuring temperature stability in the UV adhesive synthesis process. The fan 600 helps to accelerate the heat dissipation of the UV lamp 400 and improve the ultraviolet irradiation efficiency. The top cover 220 has several interfaces 230, which are used to connect thermometers, feed inlets, and nitrogen protection interfaces, respectively. By integrating UV irradiation, in-situ curing, and safety sealing, the shortcomings of traditional double-layer reactors in UV adhesive synthesis are effectively solved. It not only meets the dual requirements of light protection and ultraviolet irradiation in the UV adhesive synthesis process, but also greatly improves production efficiency and reduces production costs.

[0025] Example 2

[0026] Reference Figure 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0027] In this embodiment, a constant temperature water bath 500 is provided on one side of the cabinet 110, and a fan 600 is provided on the other side of the cabinet 110, and the fan 600 is fixed to the surface of the UV lamp 400.

[0028] The cabinet door 120 is hinged to the cabinet body 110. An observation window 130 is provided on the surface of the cabinet door 120, and a curtain is provided on the surface of the observation window 130.

[0029] The vessel body 210 includes an outer layer 211, an inner liner 212 located in the inner cavity of the outer layer 211, and a sandwich layer 213 located between the outer layer 211 and the inner liner 212.

[0030] The outlet of the constant temperature water bath 500 is connected to the inlet of the vessel body 210, and the outlet of the vessel body 210 is connected to the return port of the constant temperature water bath 500. The reaction vessel 200 is movably connected to the vessel body 210 by bolts.

[0031] The support base 350 is fixed to the top of the top cover 220, the reducer 340 is fixed to the top of the support base 350, the drive motor 330 is fixed to the top of the reducer 340, and the drive motor 330 is connected to the input shaft of the reducer 340.

[0032] The stirring shaft 310 is located in the inner cavity of the inner liner 212, and the other end of the stirring shaft 310 extends through to the outside of the vessel body 210 and is connected to the output shaft of the reducer 340.

[0033] like Figure 1-4 As shown, the observation window 130 is a quartz window. The observation window 130 allows operators to observe the reaction inside the reactor 200 without opening the cabinet door 120. The shielding curtain can cover the observation window 130 when observation is not needed, further ensuring the airtightness of the sealed cabinet 100. The water inlet of the reactor body 210 is located at the top, and the water outlet is located at the bottom. They are connected to the water outlet and water return of the constant temperature water bath 500, respectively, to achieve recycling. The UV lamp 400 penetrates the side wall of the cabinet body 110 and directly irradiates the materials inside the reactor 200. The frequency converter 360 controls the speed of the drive motor 330 and can adjust the stirring speed according to the reaction stage to improve mixing efficiency. The stirring shaft 310 extends into the inner tank 212 to ensure that the raw materials are fully mixed and improve the uniformity of the reaction. The stirring shaft 310 and the reducer 340 are connected by a coupling. The fan 600 assists in the heat dissipation of the UV lamp 400 to prevent the UV lamp 400 from generating high temperatures that affect the reaction environment.

[0034] In use, the reaction raw materials are added to the reactor 200 through interface 230, and the reaction temperature is adjusted by the constant temperature water bath 500. The drive motor 330 is started, which drives the reducer 340 to operate. The output shaft of the reducer 340 drives the stirring shaft 310 to rotate, and the stirring shaft 310 drives the stirring blades 320 to stir the reaction raw materials, making the reaction raw materials uniform and improving the reaction efficiency. During the reaction, the reaction can be observed through the observation window 130. When ultraviolet irradiation is required, the UV lamp 400 is turned on. The ultraviolet rays emitted by the UV lamp 400 pass through the sealed cabinet 100 and irradiate into the reactor 200, initiating the polymerization of UV adhesive raw materials and completing the synthesis of UV adhesive. After the synthesis is completed, the UV lamp 400 and the drive motor 330 are turned off, the cabinet door 120 is opened, and the synthesized UV adhesive is taken out. This device has a compact structure and is easy to operate. It meets the dual requirements of light protection and ultraviolet irradiation in the UV adhesive synthesis process, which greatly improves production efficiency.
