Emulsion polymerization system, emulsion polymerization method and application

Abstract

The invention provides an emulsion polymerization system, an emulsion polymerization method and application. The emulsion polymerization system comprises a reaction kettle, an initiator tank and emulsification tanks, wherein multiple emulsification tanks are connected in parallel; a reaction liquid inlet and an initiator inlet are formed in the reaction kettle; first feeding holes, second feedingholes and reaction liquid outlets are respectively formed in the emulsification tanks; the reaction liquid outlets are connected with the reaction liquid inlet of the reaction kettle; an initiator inlet and an initiator outlet are formed in the initiator tank; the initiator outlet is connected with the initiator inlet of the reaction kettle; first flow control valves are respectively arranged on pipelines where the emulsification tanks are connected with the reaction kettle. By adopting the emulsion polymerization system, different monomers are independently emulsified through the multiple emulsification tanks in parallel, and are further polymerized in the reaction kettle at different stages according to demands, so that the problem that macromolecular chain segments are randomly distributed because of reactivity ratios of different monomers can be solved, and control on polymerization numbers and positions of different monomers on the macromolecular chain segments of emulsions is achieved.

Description

technical field [0001] The invention relates to the field of chemical engineering, in particular to an emulsion polymerization system and method, and especially designs the emulsion polymerization system and method including multiple emulsification tanks. Background technique [0002] Acrylate polymers are widely used products in industrial production, and can be used to produce coatings, adhesives, plastics and other products with good performance. Acrylate polymers are usually formed by emulsion polymerization of acrylate monomers. [0003] Emulsion polymerization uses water as the dispersed phase, under the action of an emulsifier, the monomer is dispersed into an emulsion in water, and the polymerization reaction is initiated by an initiator. [0004] In the prior art acrylate emulsion polymerization device, the polymerization reaction is carried out by using a production system of a monomer emulsification tank, a reaction tank and an optional post-treatment tank.
