HARDENER AND CURE ACCELERANT WITH FLAME RETARDANCY EFFECT FOR CURING EPOXY RESINS (II)

The invention discloses a hardener and a cure accelerant with flame retardancy effect for curing epoxy resins (II). The present invention relates to innovative hardeners for curing epoxy resins, and cure accelerants for accelerated curing of epoxy resins, comprising in both cases at least one compound from the group of the esters of phosphorus-containing acids of formula (I) (as shown in the description), where for formula (I), for the radicals R1, R2, R3, R6, X and indices m, n and p, simultaneously or independently of one another: R1, R2 = simultaneously or independently of one another hydrogen or alkyl, R3 = alkyl, aryl, -O-alkyl, -O-aryl, -O-alkylaryl or -O-arylalkyl, R6 = hydrogen, alkyl or -NHC(O)NR1R2, X=oxygen or sulphur, m=1, 2 or 3, n=0, 1 or 2, and m + n=3, p= 0, 1 or 2. 本发明涉及用于固化环氧树脂的新型固化剂和用于促进环氧树脂固化的固化促进剂，所述固化剂和固化促进剂分别包含选自根据式(I)的含磷的酸的酯的至少种化合物，其中式(I)满足：基团R、R、R、R、X和指数m、n、p同时或彼此独立地满足：R、R＝同时或彼此独立地氢或烷基，R＝烷基、芳基、-O-烷基、-O-芳基、-O-烷基芳基或-O-芳基烷基，R＝氢、烷基或-NHC(O)NRR，X＝氧或硫，m＝1、2或3，n＝0、1或2，其中满足：m+n＝3，p＝0、1或2。
