Electromagnetic protection absorbing coatingIt is a special functional coating that can absorb and attenuate electromagnetic waves within a specific frequency band, thereby reducing the impact of electromagnetic radiation on the surrounding environment and other electronic devices. Good adhesion and sufficient hardness are key factors in ensuring stable coating performance. For demanding application scenarios such as aerospace and military equipment, these characteristics are particularly important.
Methods to improve adhesion
1. Surface pretreatment of substrate
- Cleaning treatment: Remove oil stains, dust, and other pollutants from the surface of the substrate to ensure that the surface is clean and free of impurities before painting.
- Physical polishing or chemical etching: increase the surface roughness of the substrate, provide more mechanical bite points, and help improve coating adhesion.
- Primer use: Choosing high-performance primers compatible with absorbing coatings can improve interfacial adhesion.
2. Improve the coating formula
- Add adhesive: Introduce polymers with excellent adhesive properties as auxiliary components, such as epoxy resin, polyurethane, etc.
- Selecting appropriate fillers: Some fillers not only endow the material with absorbing function, but also enhance the interaction between the coating and the substrate.
- Surfactant: Adding an appropriate amount can reduce the viscosity of the coating, promote wetting, and allow the coating to better penetrate into the micropores of the substrate.
3. Construction process optimization
- Spraying technology: High pressure airless spraying and other methods are used to ensure uniform distribution and moderate thickness of the coating.
- Curing condition control: Adjust appropriate temperature and time parameters according to the type of coating to achieve the best curing effect.
Methods to increase hardness
1. Formula adjustment
- Selection of hardener: Adding an appropriate proportion of hardener can accelerate crosslinking reaction and form a strong network structure.
- Nanoparticle filling: Using nanoscale ceramic particles or other hard materials to fill, it can maintain the material's absorbing properties while significantly improving its hardness.
2. Post processing reinforcement
- Heat treatment: After annealing at a certain temperature, the internal stress of the coating can be released, while promoting the rearrangement of molecular chains and further consolidating the coating.
- Surface modification: For example, UV curing or plasma treatment can improve surface hardness without compromising absorption performance.
