摘要
Abstract
Butadiene rubbers(BR)9000 produced by 10 domestic synthetic rubber manufacturers,such as PetroChina,Sinopec and some private enterprises,the molecular weight and distribution,microstructure,properties of raw rubber,properties of vulcanized rubber and vulcanization properties of them were compared according to the national and industrial standards.The results showed that the molecular weight distribution of BR9000 was at the same level and was wider;the volatile component were lower than 0.09%except for enterprises b,d and e;the ash contents were similar;the gel contents were slightly higher of enterprises b and g,and were the same for other firms;the Mooney viscosities of the raw rubber were between 42 and 46,which were basically close;the vulcanization rates were basically the same;the constant elongation stress,tensile strength and elongation at break were all at the same level.The technical indicators for BR9000 of domestic production had reached excellent products of the national standard.关键词
