Abstract

The invention discloses a synthetic method of a high-compactness phosphoric-acid-based wave-transmitting material. The method comprises the following steps: mixing a 85% aluminum dihydrogen phosphate solution, a curing agent and an additive according to a ratio of (15-20) to (10-15) to (5-10) to obtain a mixture, adding 3-5mL of a nickel or iron salt solution with concentration of 0.05-0.1mol / L into the mixture, and ultrasonically processing to obtain a precursor; and soaking quartz fiber cloth with the obtained precursor under the effect of ultrasonic waves, and finally performing high-temperature calcination in a tubular furnace to obtain the high-compactness phosphoric-acid-based wave-transmitting material. The method is simple, high temperature and high pressure are not needed, and the obtained phosphoric-acid-based wave-transmitting material is high-temperature-resistant and good in compactness and wave-transmitting property.

Description

Technical field [0001] The invention relates to a method for synthesizing wave-transmitting materials, in particular to a method for synthesizing high-density phosphate-based wave-transmitting materials. Background technique [0002] High-temperature wave-transmitting materials refer to materials that have a transmittance greater than 70% for electromagnetic waves with a wavelength of 1 to 1000 mm and a frequency of 0.3 to 300 GHz at a sufficiently high temperature. In practical applications, the dielectric constant and the dissipation factor are two important indicators to measure the wave-transmitting ability of the wave-transmitting material. According to the use environment of the wave-transmitting material, other properties other than the wave-transmitting rate need to be considered, such as long actual High temperature resistance, high rigidity, dimensional stability, flame retardancy, toughness, chemical resistance, wear resistance, aging resistance, etc. [0003] The struc...
