Abstract

The invention discloses a polyurethane thermal-insulation composite board which comprises a polyurethane thermal-insulation layer and back lining layers arranged on the inner and lower surfaces of the polyurethane thermal-insulation layer, wherein the polyurethane thermal-insulation layer is prepared from a high-performance polyurethane rigid foam material. The high-performance polyurethane rigid foam material is prepared from polyester polyol, diphenylmethane diisocyanate, hexamethylene diisocyanate, polyacrylate, styrene-butadiene rubber, cyclohexylamine, triethylenediamine, stannous octoate, a foaming agent, hydroxy silicone oil, a flame retardant, expanded perlite, attapulgite, pentaerythritol and sorbitol. The flame retardant is prepared from red phosphorus, nano magnesium hydroxide, ammonium polyphosphate, aluminum diethyl hypophosphite, piperazidine pyrophosphate and hexametapol. The polyurethane thermal-insulation composite board disclosed by the invention has the advantages of high strength, favorable impact resistance, excellent flame retardancy and long service life.

Description

technical field [0001] The invention relates to the technical field of boards, in particular to a polyurethane thermal insulation composite board. Background technique [0002] Polyurethane insulation composite board is composed of two layers of waterproof color-coated steel plates or other metal panels, and the middle is injected with flame-retardant polyurethane rigid foam. It is the best heat insulation material recognized in the world today. It can be used for large industrial plants, The roofs and walls of various buildings such as warehouses, exhibition halls, gymnasiums, cold storages, and purification workshops are integrated with heat preservation, heat insulation, load-bearing, and waterproof, and have the characteristics of rich colors and beautiful shapes. dominate the material market. However, the rigid polyurethane foam used for insulation boards has a porous structure, which makes it easier to ignite than ordinary plastics, and releases a large amount of toxi...
