▎ 摘　　要

NOVELTY - A high-strength polyurethane rigid foam material is prepared from raw materials containing combined white material first component and polyisocyanate second component. The first component includes 20-85 wt.%, preferably 30-55 wt.% polyether polyol, 5-60 wt.%, preferably 25-45 wt.% modified filler, 0.1-8 wt.%, preferably 0.5-4 wt.% foam stabilizer, 0.1-7 wt.%, preferably 0.5-5 wt.% composite catalyst, 5-30 wt.%, preferably 10-20 wt.% flame retardant and 0.1-10 wt.%, preferably 1-6 wt.% foaming agent. USE - High-strength polyurethane rigid foam material. ADVANTAGE - The foam material exhibits excellent compressive strength, good dimensional stability and thermal conductivity.
