Influence of Water Present in SiO2 on the Rubber Blends Properties – Ivanov M.T., Ezekieva M.M. (P. 2).

Effect of presence of water and diethylene glycol (DEG) on rheological and vulcanization characteristics of SiO2 filled and containing g-aminopropyl-3-ethoxy silane (APTES) rubber compounds hav been studied. Mechanical properties of vulcanizates are also measured. DEG presence results in ecranizing of SiO2 surface and prevent of adsorption of vulcanization agents. The presence of 3 % of water is enough for hydrolization of APTES ethoxy groups and their reaction with silanol groups located on SiO2 surface.

Standardization of Test Method to Estimate the Upper Temperature Limit of Vulcanized Rubber – Im W.-B., Chung K.-H. (P. 4).

Energy at break (Eb) obtained from the results of tensile test is accepted as a measure of rubber use. Dependence of Eb on temperature of various rubber compounds with different hardness value is plotted. The upper temperature limit for each compound was considered as the temperature that approached to below 50 % of Eb at room temperature. Equations to estimate the upper temperature limit of various vulcanized rubber has been proposed.

Specific Features of Sulfur Vulcanization of Hydrogenated Butadiene Acrylonitrile Rubber – Korovina Yu.V., Scherbina E.I., Dolinskaya R.M., Leizeronok M.E. (P. 6 ).

Properties of rubber compounds and vulcanized rubbers based on hydrogenated butadiene acrylonitrile rubber have been studied. The possibility of vulcanization of rubber of residual nonsaturation > 1 % by sulfur containing half-effective vulcanizing systems at 160 °С is shown.

Effect of Quaternary Ammonium Salt on Vulcanization and Mechanical Properties of Rubber Compounds Based on Acrylate Rubber –Rusetskii D.V., Scherbina E.I., Dolinskaya R.M., Leizeronok M.E. (P. 10).

Vulcanization and mechanical properties of rubber compounds based on acrylate rubber by different amount of quaternary ammonium salt (QAS) in presence of sodium stearate (SS) have been studied. The use of 1.75 pph of QAS and 2.00 pph of SS and vulcanization at 160 °С provide the best level of properties.

The Use of Mechanical Loss Data (tand) at Different Temperatures for Evaluation of Service Characteristics of Tires – Pichugin A.M., Stepanova L.I., Shcerbakov Yu.V. (P. 13).

Correlation between tand of rubber compounds at different temperatures and service characteristics of tire tread is under discussion. The higher tand at –20...–10 °C the worse is the ice and snow traction of tire; the higher tand at 0 °C the better is wet traction; the higher tand at +60 – +70 °С the higher are the losses on rolling resistance. Values of tand of rubber compounds based on styrene-butadiene and butadiene rubbers of different structure and filled by carbon black and silica have been measured by means of Instron-8032 in harmonic regime under frequency 5 Hz, compression 0.2 and amplitude 0.05. Effects of microstructure of rubber and type and amount of fillers on tand at different temperatures are shown.

Polyurethane Elastomers Based on SKU-PFL-100, Diamet X and Di(dihydroxypropyl) Ethers Dicarbonic Acids – Terentўeva N.N., Vasil`eva S.J., Kolyamshin O.A., Kol`tsov N.I. (P. 16).

The possibility of application of low toxic liquid mixes of Diamet X and di(dihydroxypropyl) ethers dicarbonic acids for solidification of isocyanate containing forpolymer SKU-PFL-100 is shown. As a result polyurethane elastomer coverings are obtainable.

Effect of Plasticizer Tofinol on Properties of Tread Rubbers – Sharipov E.N., Mokhnatkina M.G., Mochnatkina E.G., Il’yasov R.S., Ivanov V.B., Savel’chev A.P., Okhotina N.A. (P. 19).

New type of plasticizer, Tofinol have been in use in tread rubber compounds instead of the traditional one. In general all the properties of rubber compounds and vulcanized rubbers are better or of the same level; coefficient of cold resistance (characterizing short time low temperature behavior) at

–45 °C is twice as high.

Hydrocarbon Resin Pikar as an Tackiness Increasing Agent – Sharipov E.N., Mochnatkina M.G., Mochnatkina E.G., Il’yasov R.S., Ivanov V.B., Savel’chev A.P., Ochotina N.A. (P. 21).

Properties of rubber compounds with new hydrocarbon resin Pikar have been studied. Pikar is a result of the interaction of by-products of isoprene synthesis and maleic anhydride. All the properties of tire rubber compounds and vulcanized rubber with Pikar are of the same level as with pine rosin. There are even some advantages by excluding the operation of spreading of some details. The use of Pikar open the possibility to decrease the requirement for natural pine rosin.

Effect of Processing Parameters on Strength of Adhesion Contacts between Components of Thermoplastic Blends of Rubber and Polyolefines Filled with Rubber Cramp – Babich V.F., Fainleib A.M., Svyatnenko G.P., Perepelitsina L.N., LipatovYu.S. (P. 23 ).

Effect of pressure p, temperature T and the length of contact time t on strength of adhesion contacts between ethylene-propylene rubber or rubber cramp and polypropylene or polyethylene have been studied. The higher are p and t the lower is the value of T providing higher strength.

Thermo- and Fireproof Material for Power Machinery Construction – Sharova E.A., Krasovskii V.N., Smirnova E.L., Klochkov V.I. (P. 26).

Thermo- and fireproof material Polybas-03 has been developed for heat-insulation application, in particular for turbines. Its thermo-physical and mechanical properties in comparison with one of the existing materials are presented.
