Abstract

The invention provides a wave-absorbing coating. The wave-absorbing coating comprises the following raw materials in the weight percentage: 4%-6% of graphene, 5%-30% of an organic solution of polyaniline / polyurethane polymer and the remaining raw material is an additive agent. The invention also provides a film preparing method for the wave-absorbing coating. The provided wave-absorbing coating and the wave-absorbing film have the characteristics of simple preparing process and low emissivity, the film after coating with the coating is invisible in visible light, and the near infrared and infrared multiple-spectrums, the adhesiveness of the wave-absorbing coating is high and the wave-absorbing material can resist high temperature and ageing, and the coating can be painted or attached to the fabric, weapon equipment, building glass, motor vehicle glass and the surface of metal sheath.

Description

technical field [0001] The invention relates to the technical field of paints, in particular to a wave-absorbing paint and a method for preparing a wave-absorbing film using the paint. Background technique [0002] With the increasing importance of infrared stealth technology in modern information warfare, the research of microwave-absorbing coatings, especially infrared-absorbing coatings, has also received great attention. Infrared absorbing coatings refer to special functional coatings used to weaken the signals of infrared features such as weapon systems, fabrics, and glass to meet the requirements of stealth technology. The existing wave-absorbing coatings have poor performance, and the process of preparing wave-absorbing films from the coatings is relatively complicated. Contents of the invention [0003] In view of this, it is necessary to provide a wave-absorbing coating with optimized performance and a method for preparing a wave-absorbing film using the wave-abs...
