Abstract

The invention discloses a high flame retardant polyurethane rigid foam outer wall thermal insulation system. From a basic unit wall provided with a keel and connecting pieces, a prime coat thickening layer, a polyurethane rigid foam layer, an interface layer, and soft tiles, light tiles or a reflective coating are arranged in turn. In the system, the prime coat thickening layer has high adhesion and good wet bonding strength for the basic unit wall and the polyurethane rigid foam; and the high flame retardant polyurethane rigid foam outer wall thermal insulation system is foamed by pure water, and is halogen-free, flame retardant, safe and environment-friendly. The vertical face of the wall is successfully foamed on site, and the polyurethane rigid foam can be directly sprayed and foamed on the basic unit wall which is treated by the prime coat thickening layer, can reach high adhesion to the basic unit wall after 24 to 48 hours, and has the coefficient of thermal conductivity of less than 0.03W / (m.K), the vertical burning reaching V-0 level, and the water absorption of less than 2.5 percent.

Description

technical field

[0001] The invention belongs to the technical field of thermal insulation materials, and relates to a building exterior wall thermal insulation material, in particular to an environmentally friendly high flame-retardant polyurethane rigid foam external wall thermal insulation system. Background technique

[0002] At present, my country's building energy consumption has exceeded a quarter of the total primary energy consumption, reaching about 27%, which is three times that of countries at the same latitude in the world. Energy conservation and emission reduction is an important task in my country's current technological development.

[0003] At present, the energy-saving methods of buildings mainly include internal wall insulation, wall insulation and external wall insulation. In my country, external wall insulation is generally used. External wall insulation is achieved by attaching a layer of heat insulation material to the surface of the exterior wall. Th...
