Abstract
The invention relates to the technical field of polydimethylsilane, in particular to a polydimethylsilane preparation mixing device, and aims to provide a polydimethylsilane preparation mixing devicewhich is good in sodium sand, dichlorosilane and methylbenzene mixing effect, short in preparation time, simple to operate and high in safety coefficient. The polydimethylsilane preparation mixing device comprises a preparation tank, a first feeding pipe, a second feeding pipe, a lifting mechanism, a driving mechanism, a screen frame, a first annular rack, a second annular rack, a first annular sliding rail, a first slider, a concave abrasive disk, a stirring mechanism, a second annular sliding rail, a second slider and a circular abrasive disk, wherein the second annular sliding rail is fixedly connected between two side walls of the inner lower portion of the preparation tank. The polydimethylsilane preparation mixing device has the advantages of good sodium sand, dichlorosilane and methylbenzene mixing effect, short preparation time, simplicity in operation and high safety coefficient.
Description
technical field [0001] The invention relates to the technical field of polydimethylsilane, in particular to a preparation and mixing equipment for polydimethylsilane. Background technique [0002] Polydimethylsilane is a white powdery crystal at room temperature, insoluble and infusible. Decomposition and rearrangement reactions tend to occur at high temperatures of 360-420°C to obtain polycarbosilane as the reaction product. [0003] In the prior art, when preparing polydimethylsilane, metal sodium is firstly placed in toluene, and then stirred until molten under the protection of nitrogen, and then sodium sand is obtained. Then dissolving dimethyldichlorosilane in toluene to obtain a solution, and then placing the obtained sodium sand in this solution, and then under the environment of ammonia gas, and then further preparing polydimethylsilane. This method needs to be carried out step by step, thereby complicating its operation, prolonging the preparation time, and makin...
