Outdoor polyurethane absorbing material is still a new type of absorbing material, mainly composed of polyurethane

Outdoor polyurethane absorbing material is still a new typeAbsorberIts main component is polyurethane. This material has excellent absorption and weather resistance properties, and is therefore widely used in the field of outdoor absorption.

1、 Characteristics of Polyurethane Absorbing Materials

1. Absorbing performance: Polyurethane absorbing materials have a wide range of absorbing frequencies, covering frequency bands from several hundred megahertz to several thousand megahertz. They have high absorption rates and excellent absorption effects for both low and high frequencies.
   

   
   

2. Weather resistance: Polyurethane absorbing materials have excellent weather resistance and can be used outdoors for a long time without losing their absorption effect due to climate change.
   

   
   

3. Corrosion resistance: Polyurethane absorbing materials have good corrosion resistance and can resist the erosion of chemical substances such as acid, alkali, salt, etc., without affecting the absorption performance due to corrosion.
   

   
   

4. Environmental performance: Polyurethane absorbing material is an environmentally friendly material that does not contain harmful substances and will not cause pollution or harm to the environment and human health.
   

2、 Application fields of polyurethane absorbing materials

1. In the field of communication, polyurethane absorbing materials can be used for absorbing waves in communication base stations, antennas, microwave receiving equipment, satellite communication equipment, etc.
   

   
   

2. In the aviation field, polyurethane absorbing materials can be used for absorbing waves in aircraft, missiles, satellites, and other applications.
   

   
   

3. In the automotive field, polyurethane absorbing materials can be used for absorbing waves in automotive antennas, in vehicle radar, and in vehicle communication equipment.
   

   
   

4. In the field of architecture, polyurethane absorbing materials can be used for absorbing waves in building exterior walls, roofs, soundproof walls, etc.
   

   
   

5. Other fields: Polyurethane absorbing materials can also be used for absorbing waves in electronic instruments, medical equipment, acoustic chambers, etc.
   

3、 The preparation method of polyurethane absorbing material mainly includes the following steps:

1. Material preparation: Prepare polyurethane, fillers, diluents, curing agents, etc. according to the formula proportions.
   

   
   

2. Mixing: Mix the above materials evenly to make a mixture.
   

   
   

3. Spray coating: Spray the mixture onto the surface that needs to absorb waves, forming a certain thickness of absorbing layer.
   

   
   

4. Curing: Place the sprayed absorbing layer at room temperature for natural curing or heat cure it in a constant temperature box.
   

4、 Market prospects of polyurethane absorbing materials

Polyurethane absorbing materials have broad market prospects, and with the continuous development of industries such as communication, aviation, and automotive, the demand for absorbing materials is also increasing. Meanwhile, the excellent performance and environmental friendliness of polyurethane absorbing materials have also received increasing attention and favor, with broad market prospects in the future.
