20世纪40年代以来,丁腈橡胶(NBR)作为耐油型橡胶,广泛应用于汽车、石油、冶金、船舶、航空航天等领域。由于行业的发展对丁腈橡胶在宽温域、老化、介质和物理机械性能等方面提出了更为苛刻的综合性要求,传统的NBR已经不能满足这些需要。为此,国内外先后以丁腈橡胶为基础材料进行改性设计,形成了多种具有特殊用途的耐油橡胶,如NBR/PVC共混胶,由丁二烯、丙烯腈、丙烯酸丁酯三元共聚的丁腈酯橡胶,以及由NBR加氢氢化的氢化丁腈橡胶(HNBR)等。第
Since the 1940s, nitrile rubber (NBR) as oil-resistant rubber, widely used in automotive, petroleum, metallurgy, marine, aerospace and other fields. Due to the development of the industry, nitrile rubber poses more stringent comprehensive requirements in terms of wide temperature range, aging, medium and physical and mechanical properties, and the traditional NBR can not meet these needs. Therefore, at home and abroad, it has successively modified the design with nitrile rubber as the base material to form a variety of oil-resistant rubbers with special applications such as NBR / PVC blends, butadiene, acrylonitrile and butylacrylate ternary Copolymerized nitrile ester rubbers, hydrogenated nitrile rubber (HNBR) hydrogenated by NBR, and the like.
