FIELD: chemistry.

SUBSTANCE: present invention relates to a mixture of accelerators for peroxide-curable mixtures of resins, which comprises a main accelerator (I) and a co-accelerator (II), wherein main accelerator (I) is a compound of formula (I):

,

and co-accelerator (II) is a compound of formula (II-1) or (II-2):

in which R¹ and R² respectively independently denote an alkyl group with one or two carbon atoms, a hydroxyalkyl group with 1–3 carbon atoms or once or repeatedly ethoxylated or propoxylated hydroxyalkyl group with 1–3 carbon atoms. Molar ratio of (I):(II) ranges from 1:1 to 5:1. Said mixture of accelerators is used as an accelerator for curing agents based on organic peroxides for use in dual component mortar systems.

EFFECT: use of this accelerator enables to prolong gelatinisation time without negative effect on properties of system, in particular, such as moderate hardening at low temperatures and low load of completely cured substances at high temperatures, which enables to preserve properties of system in entire temperature range from -10 to +40 °C.
