Description

Technical Field

[0001] The utility model relates to the technical field of silicone oil preparation, in particular to a highly efficient block silicone oil reactor. Background Art

[0002] As an important polymer material, block silicone oil has been widely used in many fields such as cosmetics, coatings, rubber, etc. Block silicone oil has excellent lubricity, heat resistance, weather resistance and biocompatibility, so the performance and efficiency of the key equipment in its production process, the reactor, are particularly important.

[0003] According to the Chinese patent publication CN202120222784.8, in this application, a liquid storage tank is installed on the upper end surface of the top cover, and a feeding pipe is constructed on the upper end surface of the liquid storage tank. By opening the screw cap, the catalyst is added to the liquid storage tank, and the amount added is controlled by the quantitative bottle, and then discharged into the reaction device through the liquid inlet pipe. When adding the catalyst, the amount of the added catalyst can be quickly controlled;

[0004] Although the quantitative bottle in the application can effectively deal with the problem of difficult-to-control catalyst quantity, during use, since some surfactants may be used in the production process of block silicone oil, these surfactants are prone to form foam under reaction conditions. When the surfactant concentration reaches a certain level, the foam will exist stably and may increase. The foaming will cause the effective volume in the reactor to decrease, thereby reducing the contact area and reaction rate between the reactants, which not only prolongs the reaction time, but also may cause incomplete reaction, affecting production efficiency. For this reason, we propose an efficient block silicone oil reactor. Utility Model Content
