AN INSULATION COMPOSITION BASED ON HTPB PROPELLANTS AND A PROCESS THEREOF

摘要

This invention relates to a process for preparation of an insulation composition based on HTPB propellants comprising in the steps of preparing a binder matrix comprising of liquid ingredients 38-42% Hydroxyl Terminated-Polybutadiene (HTPB), 8-10% Di-octyl-Adipate as plasticiser, 0.2 to 0.4% poly ethylene glycol Mono stearate as processing aid, 0.15-0.25% Hexanetriol as crosslinker and 4-6% capolyte as tackifier, Mixing Antimony Trioxide as fire retardent with 2 micron particle size silica and 40-48 microns particle size carbon black as fillers, Adding 1.0-1.1 Hexamethylene Di-isocynate as curative, Preparation of dough as herein described, Calendaring of insulation sheets, Curing of insulation sheets as herein described.
