Inorganic polyurethane thermal insulation composite board

Abstract

The invention discloses an inorganic polyurethane thermal insulation composite board. The composite board comprises a hollow polyurethane insulation coating, an inorganic nonmetal facing layer and a cement-based backing protective coating, wherein the inorganic nonmetal facing layer is arranged on the outer surface of the hollow polyurethane insulation coating, and the cement-based backing protective coating is arranged on the inner surface of the hollow polyurethane insulation coating; the hollow polyurethane insulation coating is made from a polyisocyanurate composite material, the polyisocyanurate composite material is used for generating viscidity to respectively combine the inorganic nonmetal facing layer with the cement-based backing protective coating on the outer surface and inner surface of the hollow polyurethane insulation coating respectively. According to the inorganic polyurethane thermal insulation composite board provided by the invention, the polyisocyanurate composite material is used for generating viscidity to combine the inorganic nonmetal facing layer and the cement-based backing protective coating in the process of foaming; furthermore, the inorganic polyurethane thermal insulation composite board has the characteristics of being good in weather resistance, high in fire resistance, excellent in overall performance and simple and convenient to construct, the integrated heat preservation and decoration can be realized, the construction period can be shortened, the construction efficiency can be improved and the like.

Description

technical field [0001] The invention relates to the technical field of building energy-saving external wall thermal insulation materials, in particular to an inorganic polyurethane thermal insulation composite board. Background technique [0002] Building energy consumption has always been the focus of our country's attention. Energy conservation and emission reduction has become a basic national policy that our country pays attention to. As a country with large energy consumption, since the late 1980s, my country has gradually implemented energy conservation measures of 30%, 50% and 65%. Three energy-saving work steps, and began to carry out beneficial attempts to implement higher energy-saving indicators in cities with conditions. With the gradual implementation of the goal of 65% energy saving in domestic buildings (Beijing has begun to implement the goal of 75% energy saving), polyurethane, as a thermal insulation material with great prospects, will gradually occupy a dom...

AI Technical Summary

Problems solved by technology

The weather resistance of the composite board is not good, and after a period of weather resistance, it will fall off or crack, deform, etc., which will bring hidden dangers to the safety of the external wall insulation system

Moreover, the comprehensive performance and production efficiency of ordinary polyurethane are not enough to meet the increasing market demand
