Reactive fire-protective formulation for rendering polyurethane rigid foam materials flame-resistant and process for preparing same.

摘要

Disclosed are a reactive fire-protective formulation containing halogen and phosphorous compounds for polyurethane rigid foam materials and a process for the preparation thereof. The formulation consists of a liquid homogeneous mixture of a polyether-polyol based on an aromatic amine or sorbitol or tetrol or a mixture thereof, a neopentane containing bromo and hydroxy groups and a compound containing phosphorus and nitrogen and is particularly suitable for the preparation of preformulated polyurethane systems (component A).
