The present paper deals with a targeted modification of two kinds of alternative additives - waste from glass production and natural mineral filler and explores their effect on the properties of polymeric materials. In the function of first alternative filler was used sludge from weighing the ingredients of glass batch in the glass production. The second used was natural aluminosilicate material based on zeolite (clinoptilolite). These alternative fillers have been modified in order to increase its efficiency, using the silanes: 3-aminopropyl-triethoxysilane, bis(triethoxysilyl)propyl-tetrasulfide and 3-(triethoxysilyl)propyl-methacrylate. In the case of alternative filler based on zeolite the influence of silanization conditions on the filler efficiency have been also studied. Prepared modified fillers were mixed into rubber compounds as partial replacement of commonly used filler – carbon black. The influence of prepared fillers on rheology and curing characteristics of rubber compounds and also on physical and mechanical properties of vulcanizates has been studied. Obtained results of measured characteristics of polymeric systems containing prepared alternative fillers were compared with the results obtained in the case of reference rubber compound with a commertially used filler – carbon black.

The presented paper deals with a study of selected rubber compounds as well as their vulcanizates with partially replaced commonly used filler by adding selected alternative fillers. Alternative fillers were mixed into rubber compounds as partial replacement of commonly used filler – carbon black. As an alternative partial replacement of common filler, we have chosen fine fractions of the waste of thermoplastics. The differences of rubber compounds were based on the amount of used alternative filler. We determined vulcanization characteristics of prepared tread compounds and physical and mechanical properties and dynamic mechanical properties of their vulcanizates. From the measured results it can be concluded that studied waste can be used in the function of filler into rubber, as partial replacement of commonly used filler.

Abstract The two most effective ways of altering the physical and mechanical properties of natural rubber are vulcanization and the addition of carbon black. There is, however, little understanding of the structural changes brought about by these processes, in spite of extensive research by chemical and physical methods. For instance, in vulcanization it is not yet decided how the sulfur atoms are incorporated in the rubber polymer, what proportion are in bridges formed between the isoprene chains, whether such bridges are formed by —C—S—S—C— or —C—S—C— links, whether one double bond is broken for each sulfur atom incorporated, and so on. An ancillary problem is the effect of certain “accelerators” on the speed of vulcanization, about which even less is known. Again in the case of reinforcement of rubber by materials such as carbon black, there is controversy on the structural relationship of the carbon black and the rubber. Until such structural problems have been solved on the molecular scale there is little hope of controlling the macroscopic properties of rubber compounds in a truly scientific manner. This paper gives a preliminary account of the application of infrared spectroscopy to some of these problems.

Oxidized Carbon

Abstract Oxidized carbon blacks impart unique properties to rubber compounds. The most interesting aspects include modified curing characteristics, good resistance to tear, and the potential to promote good adhesion of rubber compounds to brass-plated metal. When these improvements are considered in conjunction with the wide range of surface area and structure available in carbon black, it is evident that oxidized furnace blacks provide combinations of properties not previously available.

Spectroscopy Studies

In the present research, acrylic rubber (ACM) composites containing Carbon black (CB) of 70 phr alone and five different ACM hybrid nanocomposites containing a fixed content of CB (60 phr) and varied content of halloysite nanotubes (HNT) (2, 4, 6, 8 and 10 phr) were prepared by melt-blending on a open twin roll mill. The prepared composites were examined for their microstructure, physical and mechanical properties, hot air and hot oil ageing resistance. Studies revealed that addition of HNT in CB filled ACM composites resulted in superior mechanical properties, improved swelling resistance and augmented impedance to oxidation and hot oil compared to ACM containing CB alone. Further ACM composites with 6 phr of HNT demonstrated an enhancement of 31.49%, 16.15%, 39.65%, 6.39% and 28.06% respectively in stress at break, % elongation at rupture, modulus at 100% elongation, resistance to crack propagation and solvent uptake. Further the same sample exhibited retention of stress at break and elongation at rupture of 99% and 92%, 98% and 89%, 94% and 96% respectively in hot air, in IRM 901 oil and in IRM 903 oil respectively. Studies on the microstructure revealed the formation of HNT-ACM-CB intercalated structures. Fourier transform infrared spectroscopy studies confirmed the establishment of bonding of hydrogen amidst the tubular nanofiller and the ACM rubber. Field emission scanning electron microscopy studies divulged the intercalation of tubular filler by ACM rubber, black filler and curing constituents and development of local HNT-CB network. These studies prove that partial replacement of traditional CB filler with tubular HNT is a promising approach to produce ACM composites with superior mechanical, thermo-oxidative ageing and hot oil ageing properties.[Formula: see text]
