Analysis of the effect of DMDEE dimorpholine diethyl ether in building insulation materials: a new method to enhance thermal insulation performance<\/h1>\n

Introduction<\/h2>\n

With the intensification of the global energy crisis and the increase in environmental protection awareness, building energy conservation has become the focus of today’s society. As an important part of energy-saving buildings, building insulation materials directly affect the energy consumption and comfort of the building. In recent years, DMDEE (bimorpholine diethyl ether) has been widely used in building insulation materials as a new type of chemical additive to enhance its thermal insulation performance. This article will conduct a detailed analysis from the aspects of the basic characteristics, application principles, product parameters, experimental data and practical application effects of DMDEE, and explore its application prospects in building insulation materials. <\/p>\n

2. Principles of application of DMDEE in building insulation materials<\/h2>\n

2.1 Thermal insulation mechanism<\/h3>\n

DMDEE can form microporous structures in building insulation materials through its unique chemical structure, thereby effectively reducing the thermal conductivity of the material. Its mechanism of action mainly includes the following aspects:<\/p>\n

    \n
  1. Micropore structure formation<\/strong>: DMDEE can promote the formation of micropores in thermal insulation materials, increase the porosity of the material, and thus reduce heat conduction. <\/li>\n
  2. Interface effect<\/strong>: The ether bonds and morpholine rings in DMDEE molecules can form a stable interface with other components in the insulation material, reducing heat transfer. <\/li>\n

      \n
    1. Direct Mixing<\/strong>: Mix DMDEE directly with the base components of the insulation material, and distribute it evenly by stirring. <\/li>\n
    2. Solution impregnation<\/strong>: Dissolve DMDEE in an appropriate solvent, and then immerse the insulation material in the solution to allow it to absorb it fully. <\/li>\n
