Abstract

The invention aims at providing a polyisocyanurate-modified polyurethane spraying material with high flame retardance and a preparation method thereof. The polyisocyanurate-modified polyurethane spraying material is prepared by polymerizing a component A and a component B, wherein the component A contains polyether polyol 4110, polyether polyol 403, polyester polyol 3152 LA, polyester polyol 6320, water, a foam stabilizing agent, a composite amine type catalyst, a composite alkaline metal salt type catalyst, a composite flame retardant and a foaming agent; and the component B is polyphenyl polymethylene polyisocyanates. The polyisocyanurate-modified polyurethane spraying material and the preparation method provided by the invention have the advantages that in the polymerization process, the heat resistance and the flame-penetrability resistance of the prepared polyurethane foam are improved by a method which comprises the main steps of selecting and optimizing the catalysts and introducing isocyanurate groups into a polyurethane structure; simultaneously, the polyisocyanurate-modified polyurethane spraying material also has the characteristic of low smoke generation amount in burning; the flame retardance of the polyurethane foam can reach B1 level.

Description

technical field [0001] The invention relates to a polyisocyanurate modified highly flame-retardant polyurethane spraying material, which belongs to the field of polyurethane foam materials. Background technique [0002] With the positive progress in energy saving and emission reduction, the application technology of polyurethane materials has been widely promoted, and the requirements for its flame retardancy are getting higher and higher, especially GB20286-2006 "Requirements for the combustion performance of flame-retardant products and components in public places and After the promulgation and implementation of GB8624-2006 "Classification Method for Combustion Behavior of Building Materials", polyurethane foam materials are facing increasingly severe challenges in the field of fire protection. As a polymer material, polyurethane has excellent thermal insulation performance, but its special structure determines its flammability. As a flammable material, the limiting oxygen...
