Preparation method of carboxylic butadiene-styrene latex

The invention relates to a preparation method of a carboxylic butadiene-styrene latex; reaction thermal energy is provided for reaction of the carboxylic butadiene-styrene latex through high-speed water vapour; after being cooled, the water vapour is converted into high-temperature deionized water; furthermore, the high-speed water vapour is also used for driving liquid in a reaction container to rotate; the liquid in the reaction container is dispersed by a water vapour flow to form a lot of tiny steam and water mixtures; a material in the reaction container is driven to flow rapidly; substances and temperature in the reaction container are uniform to distribute; the polymerization reaction is also uniform; therefore, the final product, namely the carboxylic butadiene-styrene latex, is steady in molecular structure, easy in molecular weight control and more centralized in particle diameter distribution; the balanced and good mechanical property can be obtained; and the yield and quality of the product are increased.
