Abstract
The present disclosure relates to a resin composition for preparing polyolefin-based foamed articles having flame retardancy and flame retardant foamed articles formed therefrom. The resin composition according to the present disclosure can provide foamed articles having excellent flame retardancy and flame resistance while exhibiting a high fusion ratio and a low shrinkage ratio in the foam molding.
Claims7
A resin composition for preparing polyolefin-based flame retardant foamed articles, comprising 94 to 97 wt % of a polyolefin resin and 3 to 6 wt % of a flame retardant,
- wherein the flame retardant contains a bromine-based flame retardant, a phosphorous-based flame retardant, and a nitrogen-based flame retardant in a weight ratio of 1:0.6 to 30:0.6 to 20,
- wherein the bromine-based flame retardant is 1,3,5-triazine-2,4,6-triamine hydrobromide, polybrominated diphenyl ethers, polybrominated biphenyls, tetrabromo bisphenol A, or hexabromocyclododecane;
- the phosphorous-based flame retardant is ammonium polyphosphate, phosphoric acid, or pentaerythritol phosphate;
- and the nitrogen-based flame retardant is melamine cyanurate.
