1. Introduction
Coated absorbing materials refer to a type of functional material that is coated on the surface of an object to absorb electromagnetic waves within a specific frequency range. They are widely used in fields such as aviation, aerospace, military equipment, and civilian electronic products. Although such materials have good electromagnetic absorption properties, over time, under natural conditions such as ultraviolet (UV) radiation, humidity, and temperature changes, the material may undergo changes in physical or chemical properties, leading to a decrease in absorption performance. Therefore, research on how to enhanceCoating absorbing materialIt is particularly important to improve its aging resistance and prolong its service life.
2. Factors affecting the aging of coating absorbing materials
2.1 Environmental factors
- Ultraviolet radiation: Prolonged exposure to ultraviolet radiation can lead to the decomposition of polymer matrices, thereby weakening the structural stability of materials.
- Humidity influence: In high humidity environments, moisture can easily penetrate into the interior of the coating, causing corrosion of metal components or damage to the conductive network.
- Temperature fluctuations: Under extreme temperature conditions, material thermal expansion and contraction may result in cracks or other structural damage.
2.2 Material Characteristics
- Chemical stability: Some organic compounds are prone to react with oxygen in the air, forming oxidation products and reducing absorption efficiency.
- Interface adhesion: Insufficient adhesion between the coating and substrate can easily lead to delamination and affect overall performance.
- Microstructure: Although porous or multiphase composite structures help improve absorption efficiency, they also increase the risk of water vapor intrusion.
3. Methods for improving aging resistance and service life
3.1 Selecting appropriate raw materials
- Weather resistant resin: Choosing resin with good light stability and thermal stability as the base material, such as polyurethane acrylate (PUA), fluorocarbon resin, etc., can significantly improve the outdoor durability of the coating.
- Adding stabilizers: Adding appropriate amounts of UV absorbers, antioxidants, and mold inhibitors to the formula can effectively delay the aging process of the material.
- Metal powder processing: Processing metal powder through surface modification or coating techniques to prevent direct contact with the external environment and maintain long-term conductivity and magnetism.
3.2 Improvement of Preparation Process
- Optimize spraying parameters: Control spraying parameters such as spray gun distance, angle, and speed to ensure uniform and dense coating, and reduce the presence of small defects.
- High temperature curing treatment: Appropriately increase the curing temperature and time to promote sufficient cross-linking reaction, making the coating more robust and durable.
- Multi layer composite design: constructing composite structures composed of different functional layers, such as using a surface layerProtective coatingThe bottom layer is an efficient absorbing layer, which not only protects the core material but also enhances overall performance.
3.3 Strengthen surface protection
- Nano coating coverage: Using nanotechnology to form an ultra-thin and dense protective film on the surface of the absorbing coating, preventing moisture, oxygen, and other harmful substances from entering.
- Introduction of self-healing mechanism: Develop an intelligent coating system with self-healing ability, which can automatically heal and maintain its original performance when subjected to minor damage.
3.4 Regular maintenance and upkeep
- Cleaning and maintenance: Regularly remove surface dirt to avoid impurities accumulating and affecting the absorption effect; Simultaneously check for any damages and promptly repair them.
- Monitoring and early warning system: Install online monitoring devices to track the status of materials in real time. Once abnormalities are detected, take corresponding measures immediately to prevent potential risks.
