随着橡胶轮胎工业的迅猛发展,我国的橡胶消耗量从2003年以来一直居于世界第一位,而我国只有云南和海南少部分地区适于天然橡胶种植,天然橡胶产量严重不足,大部分天然橡胶都需要进口,使得天然橡胶一直居于高位,轮胎企业原料成本居高不下,因此提高合成橡胶使用比例,已成为解决天然橡胶资源短缺、降低企业制造成本的有效途径。异戊橡胶即顺式1,4-聚异戊二烯橡胶,因其分子结构和天然橡胶相同,所以又称为合成天然橡胶。与天然橡胶相比,异戊橡胶具有纯度高、凝胶含量少、质量均一、黏性好、流动性好、加工容易;硫化胶的
With the rapid development of rubber tire industry, China’s rubber consumption has been the world’s No.1 since 2003. In our country, only a few parts of Yunnan and Hainan are suitable for natural rubber planting. The output of natural rubber is seriously insufficient. Most of the natural rubber All need to be imported, making natural rubber always stay at a high level. The raw material cost of tire enterprises is high. Therefore, increasing the proportion of synthetic rubber has become an effective way to solve the shortage of natural rubber resources and reduce the manufacturing cost of enterprises. Isoprene rubber or cis 1,4-polyisoprene rubber, because of its molecular structure and the same natural rubber, it is also known as synthetic natural rubber. Compared with natural rubber, isoprene rubber with high purity, less gel content, uniform quality, good viscosity, good fluidity, easy processing; vulcanized rubber
