Embodiment 1

[0285] According to DE-A-10359815, a sodium diethylphosphinate solution was prepared with a P content of 7.71% by weight. 2652 g of this solution were charged and a mixture of 1348 g of aluminum sulfate solution, 70 mg of a 22% by weight iron(III) sulfate solution and deionized water was added at 80°C. The crystal suspension was filtered while hot through a suction filter and washed with hot water. The wet product of the filter was dried in a drying cabinet at 120° C. under a nitrogen atmosphere for about 18 hours, then it contained 0.2% by weight of residual moisture (RF) and 18 ppm of iron. Iron phosphinate co-precipitates with aluminum phosphinate.

[0286] The heat resistance and processing window (see table for both) exceed that of pure aluminum diethylphosphinate (Comparative Example 16).

Embodiment 2

[0288] According to DE-A-10359815, a sodium diethylphosphinate solution was prepared with a P content of 7.71% by weight. According to Example 1, this was processed by using 0.2 g of a 22% iron(III) sulfate solution to a product comprising 0.2 wt. % RF and 52 ppm iron. Iron phosphinate co-precipitates with aluminum phosphinate.

[0289] The heat resistance and processing window (see table for both) exceed that of pure aluminum diethylphosphinate (Comparative Example 16).

Embodiment 3

[0291] According to DE-A-10359815, a sodium diethylphosphinate solution was prepared with a P content of 7.71% by weight. According to Example 1, this was processed by using 3.9 g of a 22% solution of iron(III) sulfate to a product comprising 0.2% by weight of RF and 1015 ppm iron. Iron phosphinate co-precipitates with aluminum phosphinate.

[0292] The heat resistance and processing window (see table for both) exceed that of pure aluminum diethylphosphinate (Comparative Example 16).

Abstract

The invention relates to a flame retardant mixture comprising as component A) 99.9999-87% by weight of a diorganophosphinate and as component B) 0.0001- 13% by weight iron, where the sum of A) and B) is 100% by weight.

Description

[0001] related application [0002] This application is a divisional application, the parent application number is 201611272731.7, the application date is October 17, 2016, and the invention name is "flame retardant mixture, its preparation and use". technical field [0003] The present invention relates to flame retardant mixtures, their preparation and their use. Background technique [0004] According to the prior art, salts of dialkylphosphinic acids (also known as dialkylphosphinic acid salts) are used as Mg salts, Ca salts, Al salts, Sb salts, Sn salts, Ge salts, Ti salts, Fe Salts, Zr salts, Zn salts, Ce salts, Bi salts, Sr salts, Mn salts, Li salts, Na salts and K salts are used in the flame retardant mixture. [0005] Flame retardant mixtures according to the prior art have limited heat resistance. It operates within a limited temperature range in which starting materials consisting of polymers, flame retardants, glass fibers and other additives can be compounded...
