Introduction

With the global energy crisis and environmental problems becoming increasingly severe, building energy conservation has become the focus of attention of governments and society in various countries. As a key factor in improving building energy efficiency, building insulation materials have attracted much attention. As a new additive, DMAEE dimethylaminoethoxy has gradually emerged its application potential in building insulation materials. This paper aims to explore the application effect of DMAEE in building insulation materials, analyze its enhancement effect on thermal insulation performance, and provide theoretical basis and practical guidance for the development of high-efficiency and energy-saving building insulation materials.

This study first introduces the basic properties and characteristics of DMAEE, and then analyzes in detail its application effect in common insulation materials such as polyurethane foam, polystyrene foam and glass wool. Through experimental research and data analysis, the influence of DMAEE on the thermal insulation properties, mechanical properties and durability of thermal insulation materials was evaluated. Later, the application prospects of DMAEE in building insulation materials were summarized and future research directions were proposed.

1. Basic properties and characteristics of DMAEE dimethylaminoethoxy

DMAEE (dimethylaminoethoxy) is an organic compound with unique molecular structure and chemical properties. Its molecular formula is C6H15NO2 and its molecular weight is 133.19 g/mol. DMAEE is a colorless and transparent liquid with a slight ammonia odor, easily soluble in water and most organic solvents. Its boiling point is 207℃, its flash point is 93℃, and its density is 0.943 g/cm³ (20℃).

DMAEE’s molecular structure contains two functional groups, amino and hydroxyl groups, which makes it excellent reactivity and versatility. The presence of amino groups makes them basic and can be used as a catalyst or neutralizing agent; the hydroxyl groups impart good hydrophilicity and reactivity, making it easy to react with other compounds. These characteristics give DMAEE a wide range of application potential in building insulation materials.

In building insulation materials, DMAEE is mainly used as an additive.Its mechanism of action is mainly reflected in the following aspects: First, DMAEE can improve the foaming process of insulation materials, improve the uniformity and stability of the cell structure, and thus enhance the insulation performance of the material. Secondly, DMAEE can react with other components in the insulation material to form stable chemical bonds, and improve the mechanical strength and durability of the material. In addition, DMAEE also has certain flame retardant properties, which can improve the fire safety of insulation materials.

2. Current status and development trends of building insulation materials

Building insulation materials are the key factors in improving building energy efficiency and reducing energy consumption. At present, common building insulation materials on the market mainly include polyurethane foam, polystyrene foam and glass wool. Polyurethane foam has excellent thermal insulation properties and mechanical strength, but is relatively expensive; polystyrene foam has low cost, but has poor fire resistance; glass wool has good thermal insulation and sound absorption properties, but is easy to absorb water and inconvenient to construct.

With the continuous improvement of building energy conservation requirements, traditional insulation materials face many challenges. First, the thermal insulation performance of existing materials is difficult to meet increasingly stringent energy-saving standards. Secondly, the durability and fire resistance of the material still need to be further improved. In addition, environmental protection and sustainability have also become important considerations in the development of insulation materials. These challenges have promoted the research and development and application of new insulation materials, among which the innovative use of additives has become an important way to improve material performance.

DMAEE, as a new additive, has provided new ideas for solving the above problems. By optimizing the addition amount and process parameters of DMAEE, the thermal insulation performance of the insulation material can be significantly improved while improving its mechanical properties and durability. In addition, the use of DMAEE can also reduce the production cost of materials, improve production efficiency, and provide technical support for the sustainable development of building insulation materials.

3. Analysis of the application effect of DMAEE in building insulation materials

In order to comprehensively evaluate the application effect of DMAEE in building insulation materials, we selected three common insulation materials: polyurethane foam, polystyrene foam and glass wool, and conducted experimental research on the addition of DMAEE. During the experiment, we strictly controlled the amount of DMAEE and process parameters to ensure the reliability and comparability of experimental results.

In the application experiment in polyurethane foam, we set up experimental groups (0%, 0.5%, 1%, 1.5%) with different DMAEE addition amounts. Experimental results show that with the increase of DMAEE addition, the thermal conductivity of polyurethane foam gradually decreases and the thermal insulation performance is significantly improved. When the amount of DMAEE added is 1%, the thermal conductivity of the material is reduced by about 15%, while the closed cell ratio of the foam is increased by 20%, and the mechanical strength is also enhanced.

In the application experiment in polystyrene foam, we also set up experimental groups with different amounts of DMAEE addition. The results show that the DMAEE addition displayThe cell structure of polystyrene foam is improved to make it more uniform and dense. When the amount of DMAEE added was 0.8%, the thermal conductivity of the material was reduced by 12%, and the compressive strength was improved by 18%. In addition, the addition of DMAEE also improves the flame retardant performance of polystyrene foam, making it meet the B1 fire resistance standard.

In the application experiment in glass wool, we mainly investigated the effect of DMAEE on the hydrophobicity and durability of materials. Experimental results show that after adding 0.3% DMAEE, the water absorption rate of glass wool was reduced by 40%, and the performance attenuation after long-term use was significantly slowed down. At the same time, the addition of DMAEE also improves the elastic modulus of glass wool, making it easier to construct and install.

By comparatively analyzing the effect of adding DMAEE to different insulation materials, we can draw the following conclusion: the addition of DMAEE significantly improves the thermal insulation performance of various insulation materials, while improving the mechanical properties and durability of the materials. However, there are differences in the response degree of different materials to DMAEE, and it is necessary to optimize the amount of DMAEE and process parameters of DMAEE according to the specific material characteristics.

IV. The mechanism of enhancement of thermal insulation performance of building insulation materials by DMAEE

DMAEE’s enhanced effect on the thermal insulation performance of building insulation materials is mainly reflected in two aspects: microstructure optimization and thermal conduction mechanism improvement. At the microstructure level, the addition of DMAEE can significantly improve the cell structure of the insulation material. By adjusting the surface tension and viscosity during the foaming process, DMAEE promotes smaller and more uniform cell formation. This optimized cell structure not only increases the air content inside the material, but also reduces the transmission path of heat convection and heat radiation, thereby improving the insulation performance of the material.

In terms of heat conduction mechanism, the addition of DMAEE mainly reduces the heat conductivity of the material through the following ways: First, the optimized cell structure increases the gas content inside the material, and the heat conductivity of the gas is much lower than that of the solid material. Secondly, polar groups in DMAEE molecules can form hydrogen bonds with the material matrix, reducing thermal vibration of the molecular chains, thereby reducing thermal conduction of the solid parts. In addition, DMAEE can also form a dense protective film on the surface of the material to reduce surface thermal radiation loss.

Experimental data show that after adding an appropriate amount of DMAEE, the thermal conductivity of the polyurethane foam can be reduced from 0.024 W/(m·K) to 0.020 W/(m·K), the thermal conductivity of the polystyrene foam can be reduced from 0.035 W/(m·K) to 0.030 W/(m·K), and the thermal conductivity of the glass wool can be reduced from 0.040 W/(m·K) to 0.035 W/(m·K). These data fully demonstrate the significant effect of DMAEE in improving the thermal insulation performance of building insulation materials.

V. Application prospects and challenges of DMAEE in building insulation materials

DMAEE has broad application prospects in building insulation materials. With allWith the continuous improvement of energy-saving standards for buildings in the fields, the demand for efficient insulation materials is growing. As a multifunctional additive, DMAEE can significantly improve the performance of existing insulation materials while reducing production costs, and has huge market potential. It is expected that the application of DMAEE in building insulation materials will maintain an average annual growth rate of more than 15% in the next five years.

However, the application of DMAEE also faces some challenges. First, it is necessary to further optimize the amount of DMAEE and process parameters to achieve excellent performance improvement. Secondly, the long-term stability and environmental impact of DMAEE require more in-depth research. In addition, the performance of DMAEE under different climatic conditions also needs further verification.

To fully utilize the potential of DMAEE, future research directions should include: 1) developing the synergistic effects of DMAEE with other additives to further improve the comprehensive performance of insulation materials; 2) studying the application of DMAEE in new nanocomposite insulation materials; 3) exploring the role of DMAEE in the overall performance optimization of building insulation systems; 4) evaluating the environmental impact and economic benefits of DMAEE throughout the building life cycle.
