[0020] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0021] Reference Figure 1As shown, hydrogen-terminated silicone oil is a type of silicone oil obtained by reacting tetramethyldisiloxane as a capping agent with octamethyltetrasiloxane (abbreviated as D4) and using acidic substances such as sulfuric acid as a catalyst. It is a non-toxic, odorless, transparent liquid. The existing hydrogen-terminated silicone oil synthesis process is mostly carried out in a reactor, and because it needs to react and mix with a large amount of synthetic solution, the internal structure of most existing reactors is relatively simple, and the solution deposited at the bottom cannot be mixed, resulting in the problem of poor synthesis effect of hydrogen-terminated silicone oil. In order to solve this type of problem, a hydrogen-terminated continuous synthesis reactor is proposed, including a reactor body 1 and a reaction chamber 11 opened in the reactor body 1, a guide frame 131 with a top surface gradually inclined inward from top to bottom is arranged on the inner wall of the reaction chamber 11, and a bottom-raising member 2 is arranged on the lower side of the guide frame 131, and the bottom-raising member 2 includes two groups of stirring blades 21 rotatably arranged in the reaction chamber 11, and the size of the stirring blades 21 gradually decreases from bottom to top to form a In the rotation space of the lift force that makes the bottom sediment jump upward, a driving member for driving the stirring blade 21 to rotate is provided on the upper side of the stirring blade 21, a filter tank 13 is formed in the guide frame 131 for the end-hydrogen silicone oil to pass through in an orderly manner, and a filter screen plate 132 is provided in the filter tank 13 for filtering impurities in the end-hydrogen silicone oil, and a separation member 3 for quickly separating the synthetic solution is provided on the upper side of the guide frame 131; the end-hydrogen silicone oil can be synthesized in a stable environment by the arrangement of the reactor body 1 and the reaction chamber 11, and the flow guide frame 131 and the bottom lifting member 2 can be arranged to control the flow route of the synthetic solution, and the solution at the bottom of the reaction chamber 11 can be lifted up by the arrangement of the stirring blade 21, so that it can float upward and fully mix with other solutions, thereby ensuring that the synthesis of the end-hydrogen silicone oil is more sufficient, and the arrangement of the filter screen plate 132 and the separation member 3 can further ensure that the entire synthesis process is more stable and effective.

[0022] It should be noted that the shape of the guide frame 131 is as shown in FIG. Figure 1 As shown, it can help guide the synthetic solution that has just entered the reaction chamber 11, and make the synthetic solution pass through the filter tank 13 and the filter screen plate 132 in an orderly manner, so that some particulate impurities inside can be placed on the filter screen plate 132, thereby ensuring the quality and stability of the entire synthesis.

[0023] Furthermore, the separation element 3 is provided to ensure that the synthetic solution is broken up to ensure a sufficient subsequent reaction. Specifically, the separation element 3 includes a separation disk 31 rotatably arranged on the top of the reaction chamber 11, and a plurality of separation holes 311 for quickly separating the synthetic solution are provided in the separation disk 31. A rotating element for driving the separation disk 31 to rotate is provided on the upper side of the separation disk 31.

[0026] Furthermore, in order to better carry out material feeding and discharging in the entire reactor, in this embodiment, the top of the reactor body 1 is provided with a plurality of feed pipe sections 14 for feeding the end-hydrogenated silicone oil / synthetic solution, and the bottom of the reactor body 1 is provided with a discharge pipe section 15 for discharging; through the provision of the plurality of feed pipe sections 14, different synthetic solutions and end-hydrogenated silicone oil masterbatch can be orderly introduced into the reaction chamber 11, and the synthesis process can be carried out continuously until the reaction is completed, at which time it flows out through the discharge pipe section 15, and the other ends of the above-mentioned feed pipe section 14 and the discharge pipe section 15 are connected to external equipment.
