▎ 摘  要

NOVELTY - Preparation of highly reliable cyano resin wave-absorbing adhesive film involves mixing cyano resin matrix and catalyst to obtain cyano resin system, adding cyano resin system, absorbent and inorganic solid filler to a resin internal mixer, banburying and rough-mixing, fine-mixing using an open mill to obtain a wave-absorbing resin blank, placing the wave-absorbing resin blank in a precision calender, rolling, calendering, punching obtained wave-absorbing resin film through a hole puncher for forming ventilation holes. USE - Preparation of highly reliable cyano resin wave-absorbing adhesive film (claimed) used in aerospace stealth, electromagnetic protection, microwave dark room, mobile communication and military stealth. ADVANTAGE - The cyano resin absorbing glue film has controllable solidification fluidity, strong wave-absorbing performance and high reliability. The method solves the problem of uncontrollable liquidity of the absorbing film in the forming process and the problem that the exhaust is difficult to reduce the reliability of absorbing plate. The inorganic filler concentration can effectively adjust the viscosity of absorbing film, the film is in the curing process thickness and fluidity controllability state, and the inorganic fillers is low dielectric constant material. It does not affect the wave absorbing performance while adjusting the liquidity of glue film. Using the puncher to prepare air hole for absorbing film after paving, it can use vacuum bag to exhaust, which effectively improves the reliability after curing.
