Abstract

The invention discloses an inorganic material hybrid hard melamine polyurethane foam heat insulation material, a preparation method thereof and combined polyether used therein. The combined polyether comprises: a polyol flame retardant, hydroxyl calcium phosphate, an inorganic material compounded with hydroxyl calcium phosphate, glycerin, N, N, N, N, N-pentamethyl diethylenetriamine, dimethyl cyclohexyl amine, 33+ / -1Wt.% triethylene diamine's dipropylene glycol solution, organic tin, hexahydro triazine, a foaming agent 141B, water, and silicone oil AK-158. The preparation method includes: mixing the combined polyether with isocyanate in ratio, and then carrying out spraying or casting foaming moulding, thus forming the heat insulation material. The heat insulation material has the characteristics of stable physical performance, no deformation, no shrinkage, strong bonding force, low thermal conductivity, an oxygen index up to over 30%, and a combustion heat release rate increase index of less than 250W / S.

Description

technical field

[0001] The invention belongs to the field of macromolecular materials, and in particular relates to a rigid melamine polyurethane thermal insulation material cross-linked and hybridized with calcium hydroxyphosphate and isocyanate, a preparation method thereof, and a combined polyether used therein. Background technique

[0002] Due to the special structure of polyurethane foam molecules, it is easy to burn. With the continuous promotion of polyurethane energy-saving thermal insulation rigid foam application technology, the requirements for its flame retardant performance are also getting higher and higher, especially the requirements of GB8624-2012 "Classification Method for Combustion Performance of Building Materials" and GB50016-2014 "Code for Fire Protection Design of Buildings" After the promulgation and implementation, polyurethane foam is facing a severe test in terms of flame retardancy and fire resistance. At present, building energy-saving thermal...
