[0017] The present invention is further described below in conjunction with specific embodiments. It should be understood that the following embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0018] Example 1

[0019] Figure 1 It is a structural schematic diagram of the utility model.

[0020] like Figure 1 As shown, a laboratory epoxy emulsion synthesis device includes: a bottom plate 100, a bracket 200, a dispersion device 300, a flask clamp 400, a reactor 500, a constant temperature container 600, a dropping funnel 700 and a temperature control system 800. The bottom plate 100 is provided with a bracket 200, one end of the dispersion device 300 is connected to the top of the bracket 200, and the other end of the dispersion device 300 is arranged in the reactor 500. The bracket 200 is connected to the reactor 500 through the flask clamp 400, the reactor 500 is arranged in the constant temperature container 600, the dropping funnel 700 is connected to the reactor 500, and the dropping funnel 700 is provided with a temperature control system 800;

[0021] The dispersion device 300 includes: a motor 310, a screw 320 and a dispersion disk 330. The motor 310 is connected to the bracket 200. The dispersion disk 330 is connected to the motor 310 through the screw 320. The dispersion disk 330 is provided with a tooth structure 331 staggered up and down.

[0022] The temperature control system 800 includes: a temperature control element 810 , a feedback device 820 and a fixing seat 830 . The temperature control element 810 is disposed in the dropping funnel 700 . The temperature control element 810 is connected to the feedback device 820 . The feedback device 820 is fixed in the fixing seat 830 .

[0023] The rotation speed of the motor 310 is 3000 r / min.

[0024] The innovative point of the utility model is that the temperature in the reactor 500 is changed by replacing the internal liquid in the thermostatic container 600 for heating, heat preservation and cooling. The dropping funnel 700 is used for feeding, and then the temperature is read through the temperature control element 810, and then fed back to the feedback device 820 to realize the control function of the feeding temperature, so that the feeding temperature is consistent with the temperature of the liquid in the reactor 500, and the stability of the reaction is guaranteed. On the other hand, the utility model adopts a dispersion disk 330 structure, and the dispersion disk 330 is provided with a toothed structure 331 staggered up and down, which can achieve high shear strength with a motor with a rotation speed of 3000r / min. Therefore, the ultimate effect pursued by the utility model is to ensure a stable reaction temperature, an efficient dispersion speed, a high shear strength, and a stable feeding speed, so that the synthesis process is controllable, the emulsion particles are uniform, and the discharge quality is stable. The principle is: the utility model is suitable for epoxy emulsion. The background technology describes that the traditional laboratory epoxy emulsion synthesis device has certain limitations in high dispersion and stability. At the same time, there are certain limitations for using solid or high-viscosity raw materials for synthesis experiments, and the reactants are not easy to fully mix. In summary, it has a small particle size requirement, so a higher stirring speed and a more stable feeding temperature are required. First, high speed and high shear force can prevent the synthetic particles from agglomerating, and then the particles can be opened. Then, by controlling the problem of the reaction medium, the reaction environment is maintained at 80-90°C, so that the synthesis process is controllable, the emulsion particles are uniform, and the discharge quality is stable.

[0025] Compared with the traditional technology, the utility model optimizes the structure of the dispersion device and cooperates with the temperature control system to improve the overall reaction quality.

[0026] The specific implementation modes of the present invention are described above, but the present invention is not limited thereto. The present invention can also have various changes without departing from the purpose of the present invention.
