[Abstract]:Waste paper fiber insulation material is a new type of building insulation product, with the advantages of low thermal conductivity, high fire resistance, easy construction operation and so on. At present, the widely used building insulation materials in the market have their own problems: for example, inorganic insulation materials have good fire resistance, but the effect of insulation is not satisfactory; For example, organic insulation materials have the advantage of good insulation effect, but they are flammable and not fire resistant. Under this background, we put forward the research of this subject. In view of the performance defects of the current widely used insulating materials, this paper develops and develops the energy-saving and environment-friendly insulating materials by utilizing the advantages of waste paper fibers. In this paper, the basic properties of waste paper fiber insulation materials are described and studied in the following aspects: (1) the basic performance characteristics of waste paper fiber insulation materials are introduced; (2) by using the method of orthogonal test, by changing the composition of waste paper fiber insulation material, the variation law of thermal conductivity and packing density is obtained, and the main factors that affect the thermal conductivity and compressive strength are distinguished. What are the secondary factors; (3) the thermal insulation materials are tested according to the national standards. The results show that the properties of the thermal insulation materials are up to the relevant standards of the national building insulation materials. The main performance parameters are as follows: thermal conductivity 0.038W/ (m K), packing density 46.4 kg / m 3, flammability B class. Waste paper fiber insulation material is a kind of green building materials, which is beneficial to the sustainable use of resources and environmental protection. Its successful development has important practical significance.
