Abstract

Purpose This paper aims to study the effects of various compatibilisers (maleic anhydride (MAH), methyl methacrylate/butyl acrylate emulsion lattice, and adhesion system (HRH)) on properties of carbon black (CB) filled with natural rubber (NR)/styrene-butadiene rubber (SBR)/ nitrile butadiene rubber (NBR) blends). A series of NR/SBR/NBR blends at a 30/30/40 blend ratio reinforced with 45 phr of CB was prepared using the master-batch method. Design/methodology/approach The tensile properties such as the tensile strength, stress at 100, 200 and 300% elongations, and elongation at break (EB)% were studied. Additionally, the morphological properties of compatibilised and uncompatibilised composites were compared to determine the optimal compatibiliser content. Findings The influence of compatibilisers appeared on all the properties studied. The properties of the blends compatibilised with prepared emulsion are very distinct from those of blends compatibilised with MAH and adhesion systems. Research limitations/implications Interactions among the different components of blends at the interfaces have a high impact on the interfacial properties of the rubber blend. Practical implications Compatibilisers significantly improve the physicomechanical properties of the resulting composites with the loading of investigated compatibilisers because of the uniform dispersion of CB in the rubber matrix. Social implications Using blends in the rubber industry leads to high-efficiency production of low-cost products. Originality/value The rubber blending has a significant positive effect on a wide range of applications such as structural applications, aerospace, military, packaging, tires and biomedical. Hence, improving the compatibility of blends will make new materials suitable for new applications.

相容剂对三元橡胶共混复合材料固化特性和力学性能的影响

目的研究各种相容剂（马来酸酐（MAH）、甲基丙烯酸甲酯/丙烯酸丁酯乳液晶格和粘接体系（HRH））对天然橡胶（NR）/苯乙烯-丁二烯橡胶（SBR）/丁腈橡胶（NBR）共混炭黑（CB）性能的影响。采用母料法制备了一系列共混比为30/30/40的NR/SBR/NBR共混物，并用45份CB增强。设计/方法/方法研究了拉伸性能，如拉伸强度、100、200和300%伸长率下的应力以及断裂伸长率（EB）%。此外，还比较了增容和未增容复合材料的形态性能，以确定最佳增容剂含量。发现增容剂对所研究的各项性能均有影响。用所制备的乳液增容的共混物的性能与用MAH和粘合体系相容的共混物非常不同。研究局限性/含义共混物不同组分在界面处的相互作用对橡胶共混物的界面性能有很大影响。实际意义由于CB在橡胶基体中的均匀分散，在所研究的相容剂的负载下，相容剂显著改善了所得复合材料的物理力学性能。社会影响在橡胶工业中使用共混物可以高效生产低成本产品。独创性/价值橡胶共混对结构应用、航空航天、军事、包装、轮胎和生物医学等广泛应用具有显著的积极影响。因此，提高共混物的相容性将使新材料适合新的应用。
