Abstract
The invention provides polyvinyl chloride paste resin used for preparing bottle caps and a method for producing the same. The method for preparing the polyvinyl chloride paste resin comprises the following steps of: mixing water, an activating agent, sodium metabisulfite and seeds, adding monomers of vinyl chloride into the mixture for reaction, and when the temperature of the mixture is between 44 and 48 DEG C, continuously adding a catalyst until the reaction is ended; and controlling the speed of feeding the remained monomers of vinyl chloride so as to keep the temperature of the reaction system between 41 and 44 DEG C, adding an emulsifying agent when the reaction temperature is between 42 and 44 DEG C, and when the temperature sharply rises and the pressure is unchanged or drops, namely the reaction is ended, adding polyoxyethylene lauric acid ester into the mixture to obtain the finished product, wherein the grain size of the finished product is 0.2 to 1.3mu m, and the distribution of the grain size is uniform. In the method, the polymerization degree is improved by lowering the temperature of the polymerization reaction and the level of residue of the polyvinyl chloride is lowered by prolonging the recovery time, so that the production requirement of the polyvinyl chloride paste resin which is the special material used for producing the bottle caps is met.
