Abstract
A flame retardant comprising (A) ethylenediamine-containing zinc phosphate and (B) a metal compound.
Claims22
A flame retardant comprising (A) ethylenediamine-containing zinc phosphate, (B) a metal compound and (C) a 1,3,5-triazine derivative and/or (D) a phosphorus-containing compound, wherein:
- (B) the metal compound is at least one member selected from the group consisting of magnesium hydroxide, aluminum hydroxide, calcium hydroxide, zinc hydroxystannate, zinc oxide, nickel oxide, tin oxide, antimony oxide, zirconium oxide, molybdenum oxide, copper oxide, iron oxide, zinc borate, zinc stannate and zeolite;
- (C) the 1,3,5-triazine derivative is at least one member selected from the group consisting of melamine, cyanuric acid, a cyanuric acid derivative, isocyanuric acid, an isocyanuric acid derivative, a melamine cyanurate and melamine isocyanurate;
- (D) the phosphorus-containing compound is at least one member selected from the group consisting of red phosphorus, ammonium polyphosphate, a phosphoric acid ester, melamine phosphate, melamine polyphosphate, guanidine phosphate and ethylenediamine phosphate;
- wherein a formulating ratio of (A) the ethylenediamine-containing zinc phosphate to (B) the metal compound is from 0.1 to 10 by weight ratio;
- and
- wherein a formulating ratio of the total amount of (A) the ethylenediamine-containing zinc phosphate and (B) the metal compound to (C) the 1,3,5-triazine derivative and/or (D) the phosphorus-containing compound is from 0.1 to 10 by weight ratio.
