(接第4期)3.对主体生胶的改性常用的橡胶主体材料,因为是大众化产品,有些性能指标无法满足个别产品的使用性能要求,因此,对主体生胶进行化学改性是配方设计人员为提高配方性能必须考虑的一条思路。本课题主要对顺丁橡胶(BR)、丁苯橡胶(SBR)、天然橡胶(NR)进行了功能化与共混改性,期望能得到理想物理性能的提高,而试验结果亦表明,主体生胶改性后,其物理机械性
(Then No. 4) 3. Modification of the main body of the rubber Commonly used rubber body material, because it is popular products, some performance indicators can not meet the performance requirements of individual products, therefore, the main raw rubber chemical modification is the formula A thought that designers must consider to improve formulation performance. The subject of the main butadiene rubber (SB), styrene-butadiene rubber (SBR), natural rubber (NR) were functionalized and blended modification, expectations can be to achieve the desired physical properties, and test results also show that the main raw rubber Modified, its physical and mechanical
