Ways to obtain amides containing salts 3d-metals based on tall oil rosin and studying their influence on the properties of the system "rubber - brassed metal cord"
This article discusses how to obtain amide-containing salts of 3d-metals based on tall rosin. A scheme of obtaining amide containing salts 3d-metals. The scheme of obtaining amide-containing salts of 3d-metals presented here. Ammonolysis maleopimaric acid was carried out, the technological parameters of the process were identified. Found that the process of ammonolysis affected by the following controlled technological factors: the ratio of the components, the temperature of the reaction medium and the duration of holding ammonolysis. The results of studies of the effect of additives on the received technical and technological properties of the elastomer compositions, adhesion and corrosion resistance rubber-systems are presented. The most efficient promoters are metal-cord-rubber adhesion systems for use in the manufacture of tires fitted. Providing the necessary technological properties of manufacturing rubber compounds achieved when using elastomeric compositions consisting of a cobalt salt of amide MTC. Found that necessary to adjust the composition of the vulcanizing system using the synthesized compounds. It was revealed that the elastomeric composition comprising cobalt salt of amide maleated rosin and cobalt naphthenate are less susceptible to oxygen and air at elevated temperature compared to rubber containing salts Mn (II) and Cr (III) amide MTC. The results of studies of bond strength rubber with steel showed that the adhesive properties of rubber-systems with the test components depend on the dosage and rubber compound. It was determined that the introduction of salts of Co (II), based on amide maleated tall oil rosin at a dosage of 1.5 wt. parts per 100 wt. phr produces indicators adhesion and corrosion properties at the level of those with industrial modifier cobalt naphthenate. The results of research of obtained compounds influence on the technical and technological properties of the elastomer compositions, adhesion and corrosion resistance of rubber-cord systems are given.
