Technical Field

[0001] The utility model relates to the technical field of silicone resin production, in particular to a silicone resin heat resistance modification device. Background Art

[0002] Silicone resin, a polymer material based on organosilicon compounds, is renowned for its excellent heat resistance, electrical insulation, chemical stability, and weather resistance. It is widely used in coatings, sealants, electronic packaging materials, and other fields. However, in some cases, to meet the needs of specific application scenarios, it may be necessary to further improve the heat resistance of silicone resin, which involves "heat resistance modification."

[0003] In the existing technology, the heat resistance modification of silicone resin requires adding an appropriate amount of inorganic filler (such as silica, graphene, etc.) and mixing the liquid silicone resin and the inorganic filler through a stirring device. However, the stirring method of the existing stirring device is relatively simple, resulting in uneven mixing of the silicone resin and the inorganic filler, resulting in poor mixing effect of the silicone resin and the inorganic filler. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the heat resistance of silicone resin needs to be modified by adding an appropriate amount of inorganic filler (such as silicon dioxide, graphene, etc.), and the silicone resin and the inorganic filler in liquid state are mixed by a stirring device. However, the stirring mode of the existing stirring device is relatively simple, resulting in uneven mixing of the silicone resin and the inorganic filler, thereby resulting in poor mixing effect of the silicone resin and the inorganic filler.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a heat-resistant modification device for silicone resin, comprising: a mixing barrel, wherein a rotating rod is movably embedded on one side of the inner wall of the mixing barrel; and further comprising:
