Abstract

A flame-retardant high-damping material includes 100 parts by mass of styrene elastomer; from 68 to 72 parts by mass of high-viscosity oil having a kinematic viscosity of 380 mm2/s or more at a temperature of 40° C.; from 72 to 132 parts by mass of melamine polyphosphate flame retardant; from 121 to 173 parts by mass of organic phosphinic acid metal salt flame retardant; and from 90 to 186 parts by mass of tackifying resin.

First claim

The invention claimed is:

1. A flame-retardant high-damping material, comprising:
100 parts by mass of styrene elastomer;
from 68 to 72 parts by mass of high-viscosity oil having a kinematic viscosity of 380 mm 2 /s or more at a temperature of 40° C.;
from 72 to 132 parts by mass of melamine polyphosphate flame retardant;
from 121 to 173 parts by mass of organic phosphinic acid metal salt flame retardant; and
from 90 to 186 parts by mass of tackifying resin.

2. The flame-retardant high-damping material according to claim 1 , further comprising magnesium hydroxide and carbon as flame retardant aids.
