TH63306B - Modified natural rubber Method for the production of modified natural rubber Tire and tire elements - Google Patents

Abstract

DC60 (24/08/16) The proposed invention provides for modified natural rubber, which presents a graft polymerization or binding reaction. binding of a more efficient polar group-containing compound and therefore there is a factor Excellent low loss, abrasion resistance and crack resistance. When used as a rubber element, the rubber composition for which modified natural rubber is used and the car tire is used. in the present invention The polar group-containing compound is grafted polymerization. Or clamped under mechanical shear force with natural rubber raw materials with 0.4% nitrogen content by mass or less. Modified natural rubber offers highly efficient graft polymerization or polar group-containing compounds. than and therefore there is a factor Excellent low loss abrasion resistance and crack resistance When used as a rubber element, the rubber composition for which modified natural rubber is used and the tire is use that rubber element in the present invention The polar group-containing compound is grafted polymerization. or clamped under mechanical shear force with natural rubber raw materials with nitrogen content 0.4% by mass or less -------------- ---------------------------------------------------- ------------------------ The proposed invention arranges for modified natural rubber to present a reaction More efficient graft polymerization or the binding reaction of a polar group-containing compound. And hence has excellent low loss factor, long service life and crack resistance. when used as a rubber element rubber element where modified natural rubber and car tires are used I assemble that rubber in the invention presented Polar group-containing compounds are graft polymerized or bonded under mechanical shear force to natural rubber raw materials. with a nitrogen content of 0.4% by mass or less
