Application of hybrid systems MgO-SiO2 / multiwalled olygomeric silsesquioxanes as promoters of ceramization in silicone composites for covers of electrical cables

摘要

The invention solves the problem of application of the hybrid systems MgO€¢SiO 2 /multiwalled olygomeric sisesquioxanes as promoters of ceramization in the silicone composites destined for covers of electrical cables. The systems are composed of magnesium silicate and from 0.1 to 50 weight parts, favourably 10 weight parts, of the silsesquioxanes containing R 1 - R 8 , where R 1 to R 8 is alkyl-group and/or groups, or alkoxy-, or methacryloxy-, or glycidoxy-, or amino-, or vinyl-, or perfluoro- or their mixture, used for its modification.
