Delay type high-centipoise molecule dynamic synthesis device

Abstract

The invention relates to a delay type high-centipoise molecule dynamic synthesis device which is suitable for the field of macromolecule polymerization, and especially suitable for high-centipoise macromolecule synthesis. The delay type high-centipoise molecule dynamic synthesis device has the main structure as follows: firstly, a mixer is arranged in a dynamic synthesis device body, an upper-guiding blade is arranged at the upper end of a mixing shaft of the mixer, a dispersing blade is arranged at the lower end of the mixing shaft of the mixer; secondly, a monomer unit, a catalytic medium inlet, a heating medium inlet and a solvent inlet are formed in the bottom end of the dynamic synthesis device body, and are hollow pipelines; the tail ends of the pipelines all point to the position of a center shaft of the mixer, and also point to the edge of the dispersing blade at the lower end of the mixer. When the delay type high-centipoise molecule dynamic synthesis device works, each monomer, medium, solvent and catalyst are injected from respective inlets, and collected to the center shaft of the mixer or the edge of the dispersing blade, fully mixed and dispersed by the dispersing blade and polymerized, and guided to the upper end of a reaction kettle by the upper-guiding blade after the polymerization is completed within a short time, and output through a discharging hole.

Description

Technical field: [0001] The delayed high centipoise molecular dynamic synthesis device is suitable for the field of polymer polymerization, especially for the synthesis of high centipoise polymers. Background technique: [0002] Polymer synthesis mostly uses traditional polymerization kettles. Traditional polymerization kettles are equipped with heating devices and stirring devices. The process is often like this: add monomers to be reacted in the kettle, and add free radical generators such as hydrogen peroxide after blocking oxygen. , dicumyl peroxide, etc., some condensation polymerization reactions add acid dehydration catalysts, etc., and in this case, in some polymerization reactions, such as polystyrene synthesis reactions, due to the fast monomer polymerization reaction speed, the free radical life is only Below 0.4*10-3 seconds, the viscosity of the polymerization product is high, and the viscosity of the product is more than 20,000 to 30,000 centipoise. If the cont...

[0002] Polymer synthesis mostly uses traditional polymerization kettles. Traditional polymerization kettles are equipped with heating devices and stirring devices. The process is often like this: add monomers to be reacted in the kettle, and add free radical generators such as hydrogen peroxide after blocking oxygen. , dicumyl peroxide, etc., some condensation polymerization reactions add acid dehydration catalysts, etc., and in this case, in some polymerization reactions, such as polystyrene synthesis reactions, due to the fast monomer polymerization reaction speed, the free radical life is only Below 0.4*10-3 seconds, the viscosity of the polymerization product is high, and the viscosity of the product is more than 20,000 to 30,000 centipoise. If the control is not proper, the monomer will explode in the kettle, that is, almost all monomers will polymerize in a short time , so that a large amount of heat is released, and cannot be removed in time, so that the reasonable molecular structure is destroyed, and even the mechanical structure of the reactor is damaged, causing serious accidents or failures
