Study of impact of tribotechnical composition on rubber technical products to assess its applicability in wheeled transport engine

Tribotechnical coating helps to reduce the friction factor and improves the performance of the internal-combustion engine, but in the process, the generic components of the engine oil and other additives interfuse together. Besides, the coating mixture excretes acids and can destroy general mechanical rubber goods and metals. For this research the oil-gasoline-resistant rubber was used which is half-disk shaped with the dimensions of 27x7x2 mm. These samples of rubber have been heated to 110-C and exposed to generic components of engine oil, tribotechnical coating 'ACTIVE PLUS' and strong acid H2SO4. In the total, the volume of the tribotechnical coating and engine oil was approximately 1 % of strong acid H2SO4. The article describes most common properties of aged rubbers such as rubber hardness, resilience, elasticity after exposure to generic components of engine oil and its additives. Results were obtained in the laboratory where samples of rubber were exposed to heat, engine oil, tribotechnical coating in conditions of absence of mechanical load. This study has identified an important issue according to which sulfuric acid destroys the system of oil-ultrafine particles in the absence of swelling of rubber. © Published under licence by IOP Publishing Ltd.
