FIELD: chemistry.
SUBSTANCE: anticorrosion mastic is obtained in a single process cycle. The process involves loading bitumen at 130°C. Technical sulphuric acid is then added for 1.5-2 hours at 130°C. Further, the product is stabilised at 150°C for 4 hours. Additives are then added - industrial oil, butyl rubber, thermoplastic elastomer - at 140°C. The components are continuously stirred after each process cycle for 60-180 minutes.
EFFECT: improved physical and chemical characteristics of the obtained anticorrosion mastic owing to improvement of its composition and optimisation of the production technology.
