Comparing Strength Properties of Natural and Synthetic Rubber Mixtures
Sustainable Construction and Design 2011 COMPARING STRENGTH PROPERTIES OF NATURAL AND SYNTHETIC RUBBER MIXTURES T. Renner, L. Pék Institute for Mechanical Engineering Technology, Faculty of Mechanical Engineering, !"#$%&'$(#%*#+(",'+$-.%/122P.%45#67,- www.geti.gek.szie.hu Abstract: During in our research work we examine the condition of developing elastomer – metal connection at manufacturing machine – and car industry hybrid parts. As a first step we have carried out comparison tests relating to the strength properties of synthetic – and natural rubber mixtures. During tests we have compared four mixtures used often in the practice (NR, NBR, EPDM, CR) in three characteric hardnesses (43 Sh 0, 57Sh 0, 72Sh 0). In addition to hardness we have measured the elongation at rupture and the density, too. As a continuation of our tests we researched what connection is between the surface roughness of metal plate and the elastomer – metal bonding formed. Keywords: rubber mixtures, latex, hybrid parts, strength properties 1 INTRODUCTION: CHARACTERIZING THE MIXTURES EXAMINED The natural rubber is the most often used type of mixture of the rubber industry nowadays which is produced from the milk-like fluid (from latex) of certain tropical trees. The latex is a colloid state dispersion, the rubber is precipipated (killed) by acetic – or formic acid from it then is washed, pressed, dried or smoked [2]. After these the quality classification takes place then it is packed in to bales and according to the so called „green book” it is put into commercial circulation. This handbook was accepted by the International Federation of Rubber Producting Nations in 1960 which is a standard publication in classifying rubbers up to present days.

Ethylene‐propylene‐diene (EPDM) rubbers containing varying amounts of diene were cured with sulfur using either a moving die rheometer (MDR) or a rubber process analyzer (RPA). The effect of removing curatives and how the curing reaction changed was explored. Kinetic data was extracted from the rheology plots and reaction rate constants were determined by two separate ways: manually choosing points of interest or by a computer model. iii TABLE OF CONTENTS Page 1.

Read Full License Loading [MathJax]/jax/output/CommonHTML/jax.js Page 1/14 Abstract Halloysite nanotubes (HNTs) were incorporated into an EPDM/SBR rubber/styrene-butadiene rubber (SBR) composite by melt blending of HNTs into the EPDM/SBR blend. The mechanical properties, abrasion and swelling resistance of HNTs ranging from 2 parts per hundred rubber (phr) to 10 parts per hundred rubber (phr) were investigated in EPDM/SBR base rubber. Tensile strength, 100% modulus (modulus at 100 percent elongation), elongation at break and tear strength were evaluated at ambient temperature using electric universal tensile testing equipment in accordance with ASTM D-412. Hardness, abrasion and swelling resistance were determined using Shore-A Durometer, DIN abrader and immersion techniques, respectively. The results show that increasing HNT content increased tensile strength, tear strength, hardness (stiffness), and crosslink density. The surface morphology of tensile- fractured material was studied using eld-emission scanning electron microscopy (FE-SEM). According to FE-SEM results, the most roughness of the surface was seen at HNTs lled rubber nano-composites. 1. Introduction Without some kind of reinforcement, a rubber substance, whether polar or non-polar, has weak physico-mechanical properties [1].

I have been following the controversy over tire crumb rubber for several years and have reviewed a number of the published studies on this matter. I congratulate the governmental agencies for taking up this important matter to establish whether ground up tires used on artificial grass fields in the form of crumb rubber is a suitable for children to play on. After reviewing a number of studies I must conclude that, thus far, the studies are totally inadequate to establish the safety of tire crumb rubber for artificial grass playing fields. Background: A recent study at Yale University was done on shredded tires and tire crumb rubber by Gaboury Benoit, Professor of Environmental Chemistry, Professor of Environmental Engineering, Co- Director of the Hixon Center for Urban Ecology, Director of the Center for Coastal and Watershed Systems. Crumb rubber from tires is a very heterogeneous material coming from tires that have many different chemical compositions so it is legitimate to include shredded tires that are used on https://www.fdms.gov/fdms/getcontent?objectId=0900006481f6e980&format=xml&show..

Characterization and Surface Modification of Rubber From
Characterization and Surface Modification of Rubber from Recycled Tires Thèse Huan Liang Doctorat en Chimie Philosophiae doctor (Ph. D.) Québec, Canada © Huan Liang, 2015 Characterization and Surface Modification of Rubber from Recycled Tires Thèse Huan Liang Sous la direction de : Josée Brisson, directrice de recherche Résumé Les pneus en fin de cycle de vie soulèvent de graves problèmes environnementaux. Ils doivent être éliminés ou recyclés. En raison de leur structure réticulée, les pneus ne fondent pas ni ne se dissolvent. Ils sont généralement broyés en poudre (caoutchouc de pneu broyé, abrévié GTR). Ensuite, ces poudres sont mélangées avec une matrice (asphalte ou polymère thermoplastique) pour réutilisation. L'industrie du recyclage se heurte à deux problèmes principaux. En premier lieu, le contrôle de technique qualité est difficile à cause du manque de solubilité de la poudre et de moyens limités pour ces petites industries. Il est nécessaire de trouver des méthodes rapides et à faible coût pour améliorer la caractérisation des GTR. Dans le présent travail, nous avons mis l'accent sur l'utilisation de ces deux techniques et sur la spectrométrie de fluorescence-X (XRF), comme il y a des rapports dans la littérature démontrant que ceux-ci peuvent être utilisés, respectivement, pour déterminer la densité de réticulation, la composition en monomères et la composition élémentaire. Un deuxième problème est la faible adhérence entre la plupart des polymères et les GTR. Ceci résulte en un manque de résistance mécanique et une tendance à l'effritement des pièces fabriquées. Certaines études se concentrent sur l'ajout de monomère et d'initiateur au GTR, afin de faire une polymérisation in-situ de chaînes greffées sur la surface.

The ﬁnal proper environmental disposal of this material is a serious problem, which involves high costs and a possible waste of a material with high added value. The recycling of elastomers is a very important alternative since it is related directly to the protection of the environment, energy conservation, and sustainability. An option for companies that produce elastomeric residues is their incorporation in the formulations by producing polymeric blends. Thus, this work aims to prepare polymeric blends composed of ethylene-propylene diene monomer rubber (EPDM) and raw EPDM/EPDM residue (EPDM-r) in different concentrations, when the residue is ground at room temperature. The morphology of the residue, vulcanization characteristics, mechanical properties, and morphology of the blends were analyzed, showing promising results that point to the feasibility of using EPDM-r in the production of polymeric blends and as a possible solution to the problem of the ﬁnal disposal of solid residues.

Mechanical Properties of Rubber
8434_Harris_33_b.qxd 09/20/2001 12:30 PM Page 33.1 CHAPTER 33 MECHANICAL PROPERTIES OF RUBBER Ronald J. Schaefer INTRODUCTION Rubber is a unique material that is both elastic and viscous. Rubber parts can there- fore function as shock and vibration isolators and/or as dampers.Although the term rubber is used rather loosely, it usually refers to the compounded and vulcanized material. In the raw state it is referred to as an elastomer. Vulcanization forms chem- ical bonds between adjacent elastomer chains and subsequently imparts dimen- sional stability, strength, and resilience. An unvulcanized rubber lacks structural integrity and will “flow” over a period of time. Rubber has a low modulus of elasticity and is capable of sustaining a deformation of as much as 1000 percent. After such deformation, it quickly and forcibly retracts to its original dimensions. It is resilient and yet exhibits internal damping. Rubber can be processed into a variety of shapes and can be adhered to metal inserts or mounting plates. It can be compounded to have widely varying properties.The load- deflection curve can be altered by changing its shape. Rubber will not corrode and normally requires no lubrication. This chapter provides a summary of rubber compounding and describes the static and dynamic properties of rubber which are of importance in shock and vibration isolation applications. It also discusses how these properties are influenced by envi- ronmental conditions. RUBBER COMPOUNDING Typical rubber compound formulations consist of 10 or more ingredients that are added to improve physical properties, affect vulcanization, prevent long-term dete- rioration, and improve processability.These ingredients are given in amounts based on a total of 100 parts of the rubber (parts per hundred of rubber).
