非公路轮胎(OTR)作为矿山运输车用的轮胎,因工作环境较为苛刻,路面一般有很多碎石和尖利的矿石块,易使轮胎受到切割损伤,导致胎面崩花掉块,因此使用寿命短,仅为1000~5000h。相对于天然橡胶和顺丁橡胶,乳聚丁苯橡胶以其较为优异的耐切割性能在工程轮胎中得到大量应用。但由于客户对使用寿命要求越来越高,现用的SBR1500难以满足要求。国内外对工程胎的研究大都集中在提高使用寿
Off-Highway Tires (OTRs) As the tires for mining trucks, due to the harsh working environment, the pavement generally has a lot of gravel and sharp ore blocks, which can easily cause the tire to be cut and damaged, thus causing the tread to collapse and block, thus prolonging the service life Short, only 1000 ~ 5000h. Relative to the natural rubber and butadiene rubber, latex SBR with its more excellent cutting resistance in engineering tires have been widely used. However, due to the increasing demands of customers on the service life, the existing SBR1500 can not meet the requirements. Domestic and foreign research on engineering tires are mostly focused on improving service life
