Abstract

Provided herein is a flame-retardant polyolefin resin containing a blend which comprises 1-80 wt % of piperazine metal salts or polymers thereof, 10-80.0 wt % of nitrogen-containing synergists or phosphorus/nitrogen retardants, and 1-50 wt % of inorganic compounds, wherein the sum of the components of the blend is 100 wt %.

Claims (8)

1. A polyolefin resin containing a flame-retardant blend, wherein the flame-retardant blend comprises:

at least one condensation blend comprising a piperazine diphosphate metal salt, where

the piperazine diphosphate metal salt is selected from the group consisting of aluminum piperazine diphosphate salt and magnesium piperazine diphosphate salt.

2. The polyolefin resin of claim 1 , comprising 10 to 60 wt % of the flame-retardant blend based on 100 parts by weight of a polyolefin-based resin.

3. The polyolefin resin of claim 2 , wherein the polyolefin resin contains at least one polymer selected from the group consisting of olefin polymers and thermoplastic polyolefin-based resin of polyolefins.

4. The polyolefin resin of claim 1 , wherein the at least one condensation blend further comprises melamine polyphosphate.

5. The polyolefin resin of claim 4 , wherein the at least one condensation blend comprises 1 to 80 wt % of the piperazine diphosphate metal salt and 10 to 80 wt % of the melamine polyphosphate.

6. The polyolefin resin of claim 4 , wherein the at least one condensation blend further comprises an inorganic compound.
