Abstract

Disclosed are a foaming material, a thermal insulation cabinet, and preparation methods therefor. The foaming material comprises 100 parts of a combined polyol, 10-30 parts of a foaming agent composition, and 120-150 parts of an isocyanate. In the present invention, the type of the polyol used in a foaming system is adjusted in order to increase the content of a polyester polyol and reduce the content of a polyether polyol, such that the compressive strength of the foaming material is significantly improved without increasing or changing the injection amount.
