Abstract
The invention discloses a polyurethane heat preservation composite board which comprises a hollow polyurethane heat preservation layer and cement-based backing protection layers. The cement-based backing protection layers are arranged on the outer surface and the inner surface of the hollow polyurethane heat preservation layer, and each cement-based backing protection layer is formed by adding polymer mortar to glass fiber felt in a compound mode; the hollow polyurethane heat preservation layer is made of polyisocyanurate foam composites, and the polyisocyanurate foam composites produce viscidity in the foaming process so that the cement-based backing protection layers can be compounded on the outer surface and the inner surface of the hollow polyurethane heat preservation layer. The cement-based backing protection layers are compounded on the outer surface and the inner surface of the hollow polyurethane heat preservation layer because the polyisocyanurate foam composites produce self-viscidity in the foaming process. The polyurethane heat preservation composite board has the advantages of being good in weatherability, high in flammability, excellent in combination property and the like.
