VULICANISABLE RUBBER MIXTURE BASED ON FLUORINATED RUBBER Russian patent published in 2015 - IPC C08L27/20 C08K13/02 

FIELD: chemistry.

SUBSTANCE: vulcanisable rubber mixture based on fluorinated rubber SKF 26 includes a vulcanising agent - bifurgin, a vulcanisation activator - magnesium oxide, filler - technical carbon P-803 and additionally a magnesium lactam-containing complex salt in amount of 3 pts.wt per 100 pts.wt rubber, obtained by reacting magnesium oxide with ε-caprolactam in molten ε-caprolactam with salicylic acid at 80-150°C for 90-120 minutes in the following molar ratio of components: MgO - 1, ε-caprolactam - 2, salicylic acid - 2.

EFFECT: invention provides low viscosity and high rate of structuring of the mixture based on fluorinated rubber while maintaining physical and mechanical properties of vulcanised rubber.
