METHOD FOR COAGULATING NATURAL RUBBER LATEX

摘要

A method for coagulating a natural rubber latex, which comprises adding (1) an acid and (2) (i) at least one salt selected from the group consisting of calcium salts and ammonium salts of nitric acid, sulfuric acid, carbonic acid, phosphoric acid, hydrochloric acid and formic acid and/or (ii) a polymeric coagulating agent to a natural rubber latex under agitation, to thereby form a porous coagulated rubber. The above method for coagulating a natural rubber latex allows a high speed coagulation and a continuous operation, which results in the reduction of the operation cost and the equipment cost for the coagulation of a natural rubber latex..
