Preparation and properties of a novel bio‐based and non‐crystalline engineering elastomer with high low‐temperature and oil resistance

Abstract

A series of poly(succinic acid/sebacic acid/itaconic acid/butanediol/propanediol) bio-based and non-crystalline engineering elastomers (BEE) were obtained by changing the molar ratio of succinic acid (SA) to sebacic acid (SeA) from 5:5 (BEE-5) to 8:2 (BEE-8). We prepared bio-based engineering elastomer composites (BEE/CB) by mixing BEE with carbon black N330. The lowtemperature and oil resistance properties of the BEE/CB composites were investigated in terms of low-temperature brittleness, coefficient of cold resistance under compression, oil resistance test at different temperatures, and tensile properties. The results showed that the low-temperature brittleness temperature of the BEE/CB composites ranged from 250 to 2608C and the coefficient of cold resistance under compression was 0.18 high at 2608C for BEE-7/CB and 0.23 high at 2408C for BEE-8/CB. The oil resistance properties of BEE-7/CB were higher than those of nitrile-butadiene rubber N240S (NBR N240S), and the oil resistance properties of BEE-8/CB were even as high as those of nitrile-butadiene rubber N220S (NBR N220S).

Design and Synthesis of Novel Bio‐Based Polyester Elastomer with Tunable Oil Resistance

“…It is well known that the main factor affecting the oil resistance of materials is their polarity. The introduction of epoxy groups, [1][2][3][4] amino groups, [5,6] ester groups, [7][8][9][10] and other polar groups [11,12] have great benefits in improving the resistance of rubber products in a non-polar oils. Nitrile rubber (NBR), [13][14][15][16][17][18] acrylate rubber (ACM), [19] fluororubber (FKM), [20][21][22][23][24] fluorinated silicone rubber (FSR), [22,25] and chloroprene rubber (CR) [26][27][28] can still maintain good properties after being soaked in non-polar oils after a period of time, and the increasing of polar groups in those rubber could effectively improve their oil resistance.…”

“…In our previous work, various biobased polyester elastomers (BPEs) were synthesized with diverse properties. [7,[32][33][34][35][36][37][38][39][40][41][42] As for oil resistant application, BPE possesses innate advantages endowed by the numerous ester groups in their main molecular chains. Compared with NBR and ACM, it is feasible to adjust the oil resistance of BPEs via choosing diverse bio-based diols and diacids with different chain length.…”

Aging-Resistant Functionalized LDH–SAS/Nitrile-Butadiene Rubber Composites: Preparation and Study of Aging Kinetics/Anti-Aging Mechanism

“…Nitrile-butadiene rubber (NBR) is a synthetic rubber widely used for various applications, such as seals in the aerospace, automotive and oil petroleum industries [ 1 , 2 , 3 ]. Compared with most commercial rubbers, NBR has beneficial properties including excellent solvent resistance, bonding performance, and a wide temperature application range [ 4 ].…”
