The invisible effect of bis-(2-dimethylaminoethyl) ether in military equipment camouflage coating
Introduction
In modern warfare, stealth technology is one of the key factors in improving the survivability and combat effectiveness of military equipment. Stealth technology not only includes radar stealth, but also includes infrared stealth, visible light stealth and sound wave stealth. As a multifunctional chemical substance, bis-(2-dimethylaminoethyl)ether (DMAEE for short) has gradually attracted attention in recent years. This article will discuss in detail the invisible effect of DMAEE in military equipment camouflage coating, including its chemical characteristics, application principles, product parameters and practical application cases.
1. Chemical characteristics of DMAEE
1.1 Chemical structure
DMAEE’s chemical formula is C8H18N2O, and its structure contains two dimethylaminoethyl groups and one ether bond. This structure makes DMAEE have high polarity and reactivity, and can react chemically with a variety of materials to form a stable coating.
1.2 Physical Properties
| Properties | value |
|---|---|
| Molecular Weight | 158.24 g/mol |
| Boiling point | 210-215°C |
| Density | 0.92 g/cm³ |
| Solution | Easy soluble in water and organic solvents |
1.3 Chemical Properties
DMAEE is highly nucleophilic and alkaline, and can react with acids, alcohols, aldehydes and other compounds. In addition, DMAEE also has good thermal and chemical stability, and can maintain its performance in high temperatures and harsh environments.
2. Principles of application of DMAEE in camouflage coatings
2.1 Radar Stealth
DMAEE can be combined with radar wave absorbing material (RAM) to form a coating with high absorption. This coating can effectively absorb radar waves, reduce reflection, and thus reduce the probability of being detected by the radar.
2.2 Infrared Invisible
DMAEE can be combined with infrared absorbing materials to form a coating with low infrared emissivity. This coating can effectively reduce the infrared radiation of the equipment and reduce the probability of being detected by the infrared detector.
2.3 Visible light invisible
DMAEE can be combined with pigments and dyes to form a coating with low visible light reflectivity. This coating can effectively reduce the visible light reflection of the equipment and reduce the probability of being detected by the naked eye and optical equipment.
2.4 Sound wave invisibility
DMAEE can be combined with a sonic absorbing material to form a coating with high sonic absorbance. This coating can effectively absorb sound waves, reduce reflections, and thus reduce the probability of being detected by sonar.
