Industrial Production Method

The industrial production of DMDEE mainly uses a two-step process. The first step is to react ethylene oxide with dihydrogen to form intermediate N,N-dimethylamine (DMMEA). The second step is to further react DMMEA with ethylene oxide to finally obtain DMDEE. This method has mature processes and is relatively low in cost, which is suitable for large-scale production.

Domestic and foreign literature shows that the synthesis process of DMDEE requires strict control of reaction conditions, including temperature, pressure and catalyst selection. For example, US Patent No. 4382079A describes a method of using an acid ion exchange resin as a catalyst that can effectively improve reaction efficiency and reduce by-product generation. Chinese scholars’ research focuses more on the development of green production processes to reduce environmental pollution.

Application Fields

The main application areas of DMDEE are concentrated in the production of polyurethane foams, especially in the fields of soft foams, rigid foams, and coatings, adhesives and sealants (CASEs). It can significantly accelerate the reaction between isocyanate and polyol while adjusting the foaming speed and curing time to obtain ideal foam structure and mechanical properties.

In addition, DMDEE is also used in other types of polymer systems, such as epoxy resin curing agents and stabilizers of acrylate emulsions. This shows that DMDEE has a very wide range of applications, covering almost all chemical products that require high-performance catalysts.

The role of DMDEE in home decoration materials

Improving material performance

As a highly efficient catalyst, DMDEE’s role in home decoration materials cannot be underestimated. First, it can significantly improve the density uniformity and dimensional stability of polyurethane foam. This means that decorative materials treated with DMDEE not only have a smoother appearance, but are not prone to deformation or cracking during long-term use. For example, a German research institution found through experiments that the polyurethane foam with appropriate amount of DMDEE increased by about 20% compared to the unadded samples, while the permanent compression deformation decreased by nearly 30%.

Secondly, DMDEE helps improve the insulation properties of the materials. This is crucial for energy saving in modern buildings. According to a report by the British Institute of Architecture, exterior wall insulation panels containing DMDEE can save up to 15% of their energy consumption compared to traditional products. This is because DMDEE promotes the formation of finer pore structures, thereby increasing the overall thermal resistance of the material.

But it is also important that DMDEE can enhance the surface gloss and softness of the decorative material. This is especially critical for high-end furniture manufacturing that pursues high-quality visual effects and comfortable hand feeling experience. A well-known Japanese furniture brand has adopted fabric coating technology with DMDEE ingredients in its new sofa series, and the results show that the user satisfaction score of the new product has been improved by a full level.

Add to increase design flexibility

In addition to directly improving physical and chemical properties, DMDEE also provides designers with more creative possibilities. Due to its excellent catalytic properties, molding of complex shapes becomes easier to achieve. For example, when making ceiling ceilings with exquisite engraving patterns or special texture effects, the rational use of DMDEE can make the entire production process smoother and more efficient. Not only that, DMDEE also allows adjusting the naturalness of color transition between different areas, thus helping to complete art wall projects that require gradient color processing.

It is also worth noting that with the increasing awareness of environmental protection, more and more companies have begun to explore the research and development of recyclable decorative materials. Against this background, DMDEE has also shown great potential with its excellent characteristics. It can effectively promote the participation of bio-based raw materials in the reaction process, and then develop a new generation of home decoration solutions that meet the requirements of green and environmental protection and meet high-performance needs.
