Problems solved by technology

[0002] Materials with infrared stealth function are generally divided into non-run-in coatings. Coatings are generally composed of fillers, binders and additives. Fillers are generally divided into three types: metals, semiconductors and coloring pigments. Metal fillers are mainly used to reduce infrared radiation emissivity. Mainly Materials are metals including aluminum, copper, zinc, nickel and reduced iron, metal oxides including bismuth oxide, Cr 2 o 3 , V 2 o 3 , Sb 2 o 3 、In 2 o 3 , and ZnO, semiconductors, including ATO, ITO, ZAO, ZnS, but metal fillers are not conducive to radar stealth

Embodiment 1

[0018] A preparation method for an infrared stealth bulletproof plate, comprising the following steps,

[0019] 1. Weigh a certain amount of LaCl 3 ·6H 2 0. ALCl 3 ·6H 2 0. Put APP (ammonium polyphosphate) and absolute ethanol into the reactor, raise the temperature of the reactor to 55°C, stir at a rate of 500r / min for 2.5h, heat to 100°C, and keep reflux at 100°C for 1h; after the reflux, Cool to 45°C, pressurize and stir for 50 minutes (pressure reaches 10Mpa, stirring speed 60r / min), add N 2 Protected and calcined, the temperature was raised to 1100°C within 1 hour, and then kept for 3 hours to obtain a white solid powder;

[0020] LaCl 3 ·6H 2 0: AlC1 3 ·6H 2 The weight ratio of O: APP (ammonium polyphosphate): absolute ethanol is 1:1:2.3:1000.

[0021] 2. Mix the obtained solid powder with water, the weight ratio of solid powder and water is 1:4; prepare pick beads (diameter 0.1mm), sodium hexametaphosphate and water to make sanding liquid; pick beads, hexametap...
