METHOD FOR PRODUCING SKIM NATURAL RUBBER, TREATED SKIM, THE SKIM NATURAL RUBBER, RUBBER COMPOSITION, AND TIRE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing skim natural rubber capable of effectively reducing a non-rubber component in natural rubber latex and of recovering a rubber component with a high yield, and also to provide high-purity treated skim and skim natural rubber of which the non-rubber component in the natural rubber latex is effectively reduced, and a rubber composition and a tire having high fracture characteristics and excellent low loss properties.;SOLUTION: A method for producing skim natural rubber includes: a skim production step of producing skim by performing concentration treatment of natural rubber latex; and a pressure filtration step of performing pressure filtration of the skim and obtaining the residue thereof. Treated skim is obtained in the method for producing skim natural rubber. Skim natural rubber is produced by the method for producing skim natural rubber. A rubber composition and a tire use the skim natural rubber.;COPYRIGHT: (C)2014,JPO&INPIT
