Sums up of the Work of Russian Rubber Industry in 2014. The Main Changes of Consumption – Bondar’ L.M., Fomina A.A. (P. 4)

Analysis of the data on the production of synthetic rubber (SR) by Russian producers as well as export and import of SR is maid. Data by agency “Chim-Kurier” are in use as well as of some other sources, including custom statistics. The comparison of the changes in SR consumption before and after appearance the tire plants of leading foreign companies in Russia is also presented.

Key words: SR production, export SR, import SR

Effect of Styrene Content and Features of Molecular Structure of Solution Styrene-Butadiene Rubber on Service Properties of the Tread Rubbers – Galimova E.M., Akhmetov I.G., Borisenko V.N., Galimov R.R., Sakhabutdinov A.G. , Mohnatkina E.G. (P. 6).

Effect of styrene content and features of the molecular structure of SSBR obtained on lithium-initiating system, on the service properties of the tread rubbers has been studied. IR specters of SSBR samples are obtained, their molecular mass MM and distribution MMD, Moony viscosity, as well as glass transition temperatures Tg of SSBR samples were determined. The change of styrene content from 5.2 to 30,6 % results in the change of MMD and increase of Tg from -28 to -5°С. Moony viscosity and 1,2-units content is nearly constant. Tread rubbers based on SSBR provide the higher tgδ data at +60 °C at styrene content 16%, strength and processing properties are also satisfied. Ranking diagram of service properties of tread rubbers is presented.

Key words: SSBR, styrene content, molecular mass, tread rubbers, processing properties, strength and service properties

The Comparison of Physicochemical Properties of the Similar Grades of Russian Carbon Black – Razdyakonova G.I., Kokhanovskaya  O.A., Likholobov V.A., P’yanova L.G. (P.10).

Physicochemical properties as well as specification indicators of 10 grades of carbon blacks, produced in Russia according to GOST 7885 and ASTM D1765 standards have been compared. Iodine, oil and DBP absorption, specific surface, bulk density, and morphology of these carbon blacks were determined. The possibility of interchangeability of some types of the carbon black with the others is shown.

Keywords: carbon black, properties, specific surface, morphology, structure, bulk density, elemental composition

Effect of Structure of Para-Phenylenediamine Antidegradants on the Cure Characteristics of Rubbers Composition – Poldushova G.A., Kandyrin K.L. Reznichenko S.V. (P. 14).

The number of antioxidants, the derivatives of para-phenylenediamine, were studied, some of them were specially synthesized. Effect of the length and structure of alkyl substituent at the nitrogen atom of these derivatives on properties of filled rubber compounds is shown. Vulcanization kinetics of compounds based on isoprene rubber SKI-3 is changed if compounds are filled with carbon black. There is nearly no such effect for compounds filled with silica. The cause of these phenomenons is under discussion.

Key words: para-phenylenediamine antioxidants, silica, carbon black, vulcanization kinetics

Improvement of Processing of Cassette Oil Seals – Kopyltsov V.V., Taganova V.A. Pichkhidze S.Y., Yurovskiy V.S. (P.18).

Improved processes of design and manufacturing of cassette gaskets (rubber/metal oil seals for shafts of agricultural machines) providing simple and cheap articles of high service life are presented.

Key words: cassette oil seals, design, processing, agricultural machines

Some Features of Consumer Properties of Elastomer Seals – Shutilin  Y.F., Panov S.Y., Moiseev V.V., Korystin S.I. (P.20).

A comparative study of the main consumer properties of window sealants based on EPDM and styrene-butadiene ТПЕ was carried out. Compression set, resistance to ozone and swelling in the water were measured. The advantages of EPDM seals for plastic windows were confirmed.

Key words: EPDM, styrene-butadiene ТПЕ, compression set, ozone resistance, water resistance

Future Tire Production – Principles and Methods – Peled J. (P.22).

The 10 criteria upon which future tire plants will be built are presented. There are: capital investment, safety and quality, environment, recycling, automation, specialization, outsourcing, limited space availability, geographical considerations, change in tire construction. Analysis of validity and consequences of each one is performed. The conclusion is maid, that a change in tire production facilities is inevitable.

Key words: tire, tire plants, development of tire industry

VMI, AZ RETRAX – Reurslag D. (P.26).

For the rapidly evolving retread market VMI group offers a new AZ RETRAX key technology, replacing traditional using of precut strips of cushion rubber compound by direct extrusion of hot rubber on buffed casings. The new technology provides lower material cost and waste, lower labor costs, lower warehousing costs, higher product quality and better environmental performance. Using this new technology will be mostly beneficial in mature markets, in countries with developed road infrastructure and big industrial retreading companies.

Key words: AZ RETRAX, retreading, cushion rubber compound, direct extrusion

Study of product’s characteristics of free-radical emulsion-type styrene-butadiene copolymerization process on the basis of the Monte-Carlo method – Mikhailova T.A., Miftakhov E.N., Nasyrov  I.Sh., Mustafina S.A. (P.28).

The mathematical model of free-radical emulsion-type styrene-butadiene copolymerization process on the basis of statistical approach with the use of the Monte-Carlo method has been developed. The model allows to study properties of the product of copolymerization and to predict the values of molecular characteristics of copolymer: molecular weight distribution (or mass distribution, MMD), number-average molecular weight (Mn), weight-average molecular weight (Mw) in real time of process.

Key words: copolymerization, conversion, intrinsic viscosity, statistical approach, Monte Carlo method, MMD, Mn, Mw.
