Epoxy resin composition flame retardant, and a method for preparing the epoxy resin composition flame retardant

摘要

flame retarded epoxy composition, characterised by the fact that its components are: aluminium hydroxide or magnesium, or their mixture at any ratio of weight, in the form of powder grain size not exceeding 45 mm and a specific surface area in the range of 3 to 6 m2 / g once hydrated,trzyipu00f3u0142wodny zinc borate powder grain size not exceeding 45 mm and a specific surface area of not less than 1,5 m2 / g and weight listed ingredients in compositions of epoxy resin powders dianowu0105 ranges from 25% to 75%, and n anonapeu0142niacz glinokrzemianowy, which constitutes a layered aluminosilicate, preferably bentonitemodified dimetylowu0105 salt amoniowu0105 fatty acids, with weight modified aluminosilicate compositions of epoxy resin laminated in dianowu0105 ranging from 0,5 to 3%, and nanonapeu0142niacz glinokrzemianowy is placed on the composition in the form of przedm ieszki, containing about 30% by weight of modified aluminosilicate (approximately 70% of the number of dianowej epoxy resin epoxy 0,52 - 0,54 mol / 100g, and approximately 2% - 3 glicydooksypropylotrietoksysilanu.method for flame retarded epoxy composition is characterized by the fact that uniepalniaju0105ce powder ingredients is to warp u017cywicznej after being subjected to surface modification in gas mixing piece together to free flowing substances,and nanonapeu0142niacz glinokrzemianowy is to warp u017cywicznej in form in the mixture liquid dianowej masterbatch resin and connection krzemoorganicznego, and all the components composition is homogenised with liquid epoxy resin at elevated temperaturz dianowu0105 e in the range of 30 oc to 75 degrees in the gas mixing piece szybkoobrotowym.
