Abstract

The invention relates to a metal surface polyisocyanurate modified polyurethane sandwich panel and a production method thereof. The sandwich panel is used for cold storage thermal insulation. The sandwich panel comprises an upper metal surface layer, a lower metal surface layer and a polyisocyanurate modified polyurethane foam plastic core layer. The core layer is formed by intensive mixing reaction of compound polyether polyester polyols (white material) and polyisocyanurate (black material) which are 100:100-200 by weight ratio through a high-pressure foaming machine. The compound polyether polyester polyols comprises polyhydric alcohols, foam stabilizer, catalyst, cross-linking agent, flame retardant, water and foaming agent which are 100:1-5:1-5:2-6:5-25:0.5-3:10-30 by weight ratio. The polyhydric alcohols, the catalyst, the flame retardant and the foam stabilizer are all compounded by at least two kinds. The polyisocyanurate is high-functionality polyaryl polymethylene isocyanate. The metal surface polyisocyanurate modified polyurethane sandwich panel is good in flame retardance, excellent in weather fastness and high in size stability, and B1 standards are reached totally.

Description
