Research on the Application of New Building Recycled Insulation Materials for Walls
Summary
Researchers developed a new wall insulation material using recycled polyurethane and demonstrated through thermal performance testing that it achieves high efficiency energy savings while also providing an environmentally beneficial end-use pathway for polyurethane plastic waste.
In this paper, a new type of recycled polyurethane material is used as a new type of wall insulation material, and the new building insulation wall made of this paper has high efficiency thermal insulation and energy-saving characteristics and also has certain environmental significance. The thermal conductivity of the new building cold insulation recycled polyurethane material is 0.023 W/(m·K), and the thermal conductivity of the new building insulation wall prepared is 0.297 W/(m·K). Compared with traditional double-sided plastered porous wall tiles, it can save 85.4% of energy consumption per square meter, with higher thermal insulation characteristics and economic benefits. The preparation of a new type of building insulation wall proposed in this paper provides a new and green way for wall insulation.
