DEVELOPMENT AND STUDY OF THE PROPERTIES OF ANTI-ADHESIVE IN THE PRODUCTION OF SYNTHETIC RUBBERS OF LLC "TOLУATTIKAUCHUK"

Abstract

An effective composition of a release agent (RA) has been developed and studied, used to apply on the surfaces of press chambers and conveyor belts at the stage of coagulation, drying and briquetting of emulsion copolymer (α-methyl)-styrene-butadiene rubber (SKMS) produced by LLC «Tolyattikauchuk». Castor oil and high-boiling by-product produced by LLC «Tolyattikauchuk» are used as the initial component, significantly reduced the cost of RA. Properties of RA (homogeneous liquid of light yellow color) such as conditional viscosity, density at 20 °C, pour point, pH value of 10 % aqueous solution, physical and mechanical characteristic, «Stickiness» and «Corrosion rate» indicators compares well with serial sample and processing properties are better. «Corrosion rate» for steel (St.3) is 0,002 mm/year, the standard one is less than 0,1 mm/year. It was found that the emulsion SKMS obtained using the developed RA fully complies with the regulatory requirements for key indicators of rubber quality. A conclusion was made about the economic feasibility of the use of RA in the production of SKMS and the prospects of its use in production of butyl rubber and polyisoprene.
