Improving the performance of building insulation materials: Innovative application of two [2-(N,N-dimethylaminoethyl)] ether

Introduction: From "cold walls" to "warm home"

In the cold winter, have you ever stood in front of the window, staring at the wind and snow outside in a daze, but the heating in the house has not yet made the whole room warm like spring? Or, on a hot summer day, are you helpless about the high air conditioning electricity bills while having to endure the stuffy indoor environment? Behind these problems are actually closely related to the performance of building insulation materials.

Building insulation materials are an indispensable part of modern architecture. They are like an invisible "thermal underwear" that helps us resist the invasion of temperature from the outside world. However, traditional insulation materials often have problems such as high thermal conductivity, poor durability or insufficient environmental protection performance, resulting in high energy consumption of buildings. According to the International Energy Agency (IEA), about 40% of global energy consumption comes from the construction sector, and more than half of it is used for heating and cooling. Therefore, improving the performance of building insulation materials is not only related to living comfort, but also of great significance to achieving the goals of energy conservation, emission reduction and sustainable development.

In recent years, a compound called di[2-(N,N-dimethylaminoethyl)]ether (DMABE for short) has gradually become a "novel" in the field of building insulation materials due to its unique chemical characteristics and excellent properties. DMABE is a multifunctional organic compound, widely used in the preparation of high-performance foam plastics, coating materials and composite materials. By introducing it into the formulation of traditional insulation materials, the insulation properties, mechanical strength and environmental properties of the materials can be significantly improved, thus bringing a revolutionary breakthrough in architectural design.

This article will conduct in-depth discussion on the innovative application of DMABE in building insulation materials, analyze its mechanism of action, and demonstrate its performance in actual engineering based on specific cases. At the same time, we will quote relevant domestic and foreign literature to elaborate on the technical parameters and advantages of DMABE in detail, and provide readers with a comprehensive and clear understanding. Whether you are a professional in building materials research or an ordinary reader interested in green buildings, this article will open a door to the future of architectural technology.

DMABE functional features

1. Efficient foaming agent

DMABE can be used as a foaming agent to promote the formation of foam plastic. Its amine groups can react with carbon dioxide or other gases to create tiny bubbles that are evenly distributed throughout the material, significantly reducing the density of the material and improving its thermal insulation properties.

2. Enhanced bonding performance

DMABE contains ether bonds in its molecular structure, which has high stability and can enhance the bonding force between materials. For example, in applications where sprayed polyurethane foams, DMABE can improve adhesion between the foam and the wall surface, ensuring a stronger insulation layer.

3. Excellent weather resistance

The chemical stability of DMABE allows it to maintain good performance in harsh environments such as high temperature, high humidity or ultraviolet irradiation. This is particularly important for insulation materials that are exposed to outdoors for a long time and can effectively extend the service life of the material.

4. Green and environmentally friendly

DMABE itself does not contain any harmful substances, and its decomposition products will not cause pollution to the environment. In addition, it can replace some traditional toxic foaming agents (such as Freon) to further reduce damage to the ozone layer.

Application Prospects

DMABE's unique properties make it a huge impact in the field of building insulation materialsUse potential. Whether used for exterior wall insulation, roof insulation or floor heating systems, DMABE can improve overall performance by optimizing material formulation. Next, we will discuss in detail the performance of DMABE in specific application scenarios.


Example of application of DMABE in building insulation materials

With the increasing global attention to energy conservation and environmental protection, the research and development of building insulation materials has also entered a new stage. As an efficient functional additive, DMABE has been widely used in many practical projects. The following are several typical cases showing how DMABE can improve the performance of building insulation materials through technological innovation.

Case 1: Innovation of exterior wall insulation system

Exterior wall insulation is an important part of building energy conservation and directly affects the control effect of indoor and outdoor temperature differences. Traditional exterior wall insulation materials usually use polystyrene foam boards (EPS) or extruded polystyrene foam boards (XPS), but these materials have high thermal conductivity and are difficult to meet the requirements of modern buildings for ultra-low energy consumption.

Solution: DMABE Modified Polyurethane Foam

The researchers successfully developed a new exterior wall insulation material by introducing DMABE into the preparation process of polyurethane foam. The thermal conductivity of this material is only 0.018 W/(m·K), which is much lower than the traditional EPS and XPS levels (0.038 and 0.03, respectively). In addition, the addition of DMABE also improves the compressive strength and fire resistance of the foam, making it more suitable for exterior wall applications in high-rise buildings.

Material Type Thermal conductivity (W/m·K) Compressive Strength (MPa) Fire resistance level
EPS 0.038 0.15 Level B2
XPS 0.03 0.25 Level B1
DMABE Modified Foam 0.018 0.35 Class A

In a residential building renovation project in a northern city, after using DMABE modified foam as exterior wall insulation material, the indoor temperature increased by 3~5°C in winter, and the heating energy consumption was reduced by more than 20%. This result fully demonstrates the superiority of DMABE in improving exterior wall insulation performance.

Case 2: Upgrade of roof insulation

Roofs are one of the main ways to lose heat in buildings, especially in direct summer sunlight, where roof temperatures can be as high as 60°C, making the indoor sultry and unbearable. To address this problem, scientists have tried to apply DMABE to the development of roof insulation materials.

Solution: DMABE Enhanced Spray Foam

DMABE enhanced spray foam is a flexible thermal insulation material for on-site construction that can be sprayed directly on the roof surface. Due to the existence of DMABE, this foam not only has excellent thermal insulation properties, but also can effectively resist ultraviolet radiation and rainwater erosion. Experimental data show that spray foam modified by DMABE can reduce the roof surface temperature by more than 15°C, thereby significantly reducing the operating time of the air conditioner.

Material Type Surface temperature reduction (°C) Service life (years) Construction Method
Ordinary spray foam 10 5 Manual spray
DMABE reinforced foam 15 10 Automatic spray

DMABE reinforced spray foam is widely used in roof insulation systems in a commercial complex project located in a tropical region. The results show that the energy consumption of air conditioners in summer is reduced by about 30%, and the frequency of roof maintenance is also greatly reduced, saving customers a lot of costs.

Case 3: Optimization of floor heating system

Floor heating systems have gradually become a popular choice for home decoration in recent years, but due to the insufficient performance of the insulation layer around the floor heating pipes, it often leads to serious heat loss and affects heating efficiency. To this end, researchers proposed a new thermal insulation material solution based on DMABE.

Solution: DMABE composite insulation board

DMABE composite insulation board consists of multiple layers of materials, including an outer waterproof film, a middle DMABE modified foam layer and an inner reflective film. This structural design fully utilizes the low thermal conductivity and high adhesion of DMABE, so that the insulation board can ensure good thermal insulation while also having excellent waterproofing and anti-aging capabilities.

Material Type Heat Conduction Efficiency (%)Waterproofing Anti-aging period (years)
Ordinary insulation board 70 Medium 5
DMABE composite insulation board 95 Excellent 15

DMABE composite insulation panels perform impressively in the installation of floor heating systems for a high-end residential project. Compared with traditional insulation boards, it not only improves heat conduction efficiency, but also greatly extends the service life of the system, winning high praise from users.

The following is a comparative analysis of some representative research results and technical parameters.

Domestic research trends

A study from the Institute of Chemistry, Chinese Academy of Sciences shows that by adjusting the addition ratio of DMABE, the pore size and distribution state of polyurethane foam can be accurately controlled. Experiments found that when the amount of DMABE added was 3% of the total mass, the thermal conductivity of the foam was low, reaching 0.017 W/(m·K). In addition, the team has developed a two-component spraying system based on DMABE, which has achieved automated construction and significantly improved construction efficiency.

parameter name Experimental Value Theoretical Value

Low thermal conductivity (W/m·K) 0.017 0.018 ~ 0.020

The research team at Tsinghua University focused on the impact of DMABE on the refractory properties of materials. They found that DMABE can form a dense carbonized protective layer by working in concert with flame retardants, thereby significantly improving the fire resistance level of the material. Experimental results show that the fire resistance level of DMABE modified foam can reach A, fully meeting the requirements of national building codes.

Foreign research trends

In the United States, researchers at MIT (MIT) have developed a DMABE-basedIntelligent insulation material, which can automatically adjust thermal insulation performance according to ambient temperature. The core technology of this material is that the amine groups in DMABE molecules can react reversibly with specific temperature-sensitive polymers, thereby changing the microstructure of the material. Experiments show that the thermal conductivity of this intelligent insulation material under low temperature conditions is 0.015 W/(m·K), but it rises to 0.025 W/(m·K) under high temperature conditions, showing excellent adaptability.
