Abstract

Use of an oligomeric or polymeric compound of general formula I as an organic synergist for a flame retardant and a flame retardant in a self-extinguishing polymer composition, wherein X is a halogen; or the ring contains at least one nitrogen atom heterocyclic radicals attached to the triazine ring via one of these nitrogen atoms, R 2 is alkyl or cycloalkyl, R 1 is a divalent atomic group of piperazine of the formula; or a divalent atomic group of type; or n is an integer from 2 to 30 inclusive, m is an integer from 2 to 6 inclusive, and p is an integer from 2 to 12 inclusive endpoint, and X 1 =OH,NH 2 or X, where X and X 1 Can be the same or different, X 2 = Hydrogen or C 1 -C 4 Alkyl group.

Description

technical field [0001] The invention belongs to the field of flame retardants and flame retardants, and in particular relates to an organic material used as a synergist for the flame retardants and flame retardants. Background technique [0002] Flame retardants and flame suppressants are widely used as plastic additives to make the produced plastic materials safer for use. The use of flame retardants and flame suppressants as part of the non-conductive insulation is mandatory for many applications such as wire and cable and electrical and electronic applications. [0003] There are many types of flame retardants and suppressants available. The most commonly used are inorganic substances, halogenated organic compounds, organophosphorus compounds or other organic substances. [0004] Halogenated flame retardant additives no longer meet the conditions required by various industry and government regulations. For example, polymer resins used in e.g. electrical and electronic ...
