REFRACTORY POLYAMIDE COMPOSITION Russian patent published in 2003 - IPC

FIELD: polymers. SUBSTANCE: invention relates to technology of preparing polymeric materials of reduced inflammability, in part, to preparing compositions used in electric engineering. Composition comprises polyamide, triazine antipyrene as refractory addition taken among the following substances: melamine, melem or cyanuric acid salt and melamine and combustible mixture additionally: mixture of red phosphorus, sulfur or mixture of ed phosphorus and sulfur with antimony sulfide with the combustion catalyst: titanium oxide or iron oxide, or potassium nitrate, or mixture of iron oxide and potassium nitrate in their mass ratio from 1:3 to 1:2 and stabilizing addition: mixture of copper iodide or bromide with 1,2,3-benzotriazole in their mass ratio from 1:20 to 2:1 and saturated acid amide in the following ratio of components, wt.%: triazine antipyrene, 3-25; combustible mixture, 0.4-15.0; stabilizing addition, 0.01-1.00; saturated acid amide, 0.1-2.0; polyamide, up to 100. Invention provides the enhancement of mechanical properties of materials prepared of these compositions and resistance to combustion due to elimination of combusting drops. EFFECT: improved properties of composition. 16 ex
