[0002] Silicone potting compound refers to a type of electronic potting compound made of silicone rubber, including single-component silicone potting compound and two-component silicone potting compound.

[0003] For two-component silicone potting glue, during production, silicone rubber and various functional seasonings are mixed at a certain temperature by a vacuum kneader, and then a certain amount of vinyl silicone oil is added to adjust the viscosity to make component A, and cross-linking agents, catalysts, etc. are mixed evenly according to a proportion to make component B. When using, components A and B are mixed according to a proportion to cure.

[0004] It can be seen that its production process is mainly concentrated on component A, which is a process of fully mixing the raw materials.

Specifically, various raw materials are fully mixed through a mixing device and then extruded to obtain a finished product, and then the finished product is transported to a storage device through a transfer device for storage. During the transfer process, the high-temperature finished product is transported through the feeding pipe 11. During the transportation process, the heat in the finished product is transferred to the wall of the feeding pipe 11 and transferred to the heat exchange tube 21. The reacted raw materials are fed into the heat exchange tube 21 through the feed port 26 to preheat the raw materials. The fully preheated raw materials can be discharged through the discharge port 25. The inclined feeding pipe 11 and the heat exchange tube 21 can better add and discharge the raw materials, which can not only cool the finished product well, but also make full use of the heat of the finished product to heat the raw materials, reduce the heat required for mixing, improve the mixing efficiency, and reduce the production cost.
