Abstract
The polyol composition for polyisocyanurate foam consists of: polyester polyols based on aromatic acid anhydride 40-70 wt%; polyethylene/propylene oxide polyether polyols based on fatty amine, fatty diamine or fatty polyamine 0-10 wt%; compound containing active hydrogen atom 0-25 wt%, liquid organic fire retardant 14-25 wt%, water 1-3 wt%, catalyst 2-4.5 wt%, and supplementary material and/or additives 2-5 wt%. The hard foam prepared through one-step process has homogeneous and fine cells, and has the excellent performances in electric insulation, light weight, sound isolation, chemical corrosion resistance, etc. similar to those of PUR foam as well as pressure strength, size stability, heat insulation, flame resistance, low burning smoke amount, etc. superior to PUR foam. The present invention may be used in heat insulating material and sandwiched composite material with relatively high temperature requirement.
Description
Technical field
What the present invention relates to is a kind of polyvalent alcohol that is used for the foam materials field, particularly a kind of combined polyol for polyisocyanurate foam.
