Abstract
This invention relates to a laser-absorbing ceramic powdery material, which can be used in laser protection and laser camouflage. The ceramic powdery material is composed of: SnO2 75-95 wt.%, CuO 0-5 wt.%, Sb2O3 0-15 wt.%, ZnO 0-5 wt.%, Co3O4 0-15 wt.%, Ni2O3 0-15 wt.%, and MnO2 0-10 wt.%. The ceramic powder material is prepared by: mixing the above components uniformly, calcining at high temperatures, cooling, pulverizing, grinding and drying to obtain powdery product. The ceramic powdery material can be prepared into coating layer by adding binder, such as acrylic resin or silicone resin, or by thermal spraying onto the surface of the matrix. The ceramic powdery material has high absorbency and low reflectivity to 1.06 mu.m and 10.6 mu.m laser. The method is simple.
Description
Technical field
The present invention relates to a kind of ceramics powder material of absorbing laser, be used for lasing safety, laser camouflage.
Background technology
Existing ceramic powder is at visible light and near infrared and laser wavelength (1.06 μ m, 10.6 μ m), its reflectivity is usually between 10～90%, can be used for the camouflage color and the camouflage of visible light, the reflectivity of whiteware powder is more than 80% usually, and the reflectivity of black ceramic powder is about 8%.And the black ceramic powder has limited the application on laser stealth technology, and does not reach the requirement of laser stealth technology, but along with the development of laser acquisition technology, requires material surface the smaller the better to the reflectivity of laser.Therefore, be badly in need of the material of high-absorbable energy, antiradar reflectivity is used for laser stealth technology.
Summary of the invention
Mesh sieve of the present invention be to provide a kind of ceramics powder material of absorbing laser, little to specific absorption height, the reflectivity of laser, satisfy the laser camouflage requirement, the present invention provides a kind of ceramics powder material of absorbing laser simple preparation method simultaneously.

The batching component uses powder, and particle diameter is chemical pure or industrial chemicals less than 50 microns, and particle diameter is more little to be beneficial to syntheticly more, and particle diameter is little, and synthesis temperature can be low.
Utilize SnO
2The characteristic of semiconductor that shows after material doped carries out the preparation of material.
The preparation method of ceramics powder material of absorbing laser, simple, each component is mixed, calcining at high temperature is synthetic, and synthesis temperature is 1280～1400 ℃, through pulverizing, grinding and drying treatment, makes powder product after the cooling.
Detailed process is as follows:
According to above-mentioned composition, in ball mill, carry out wet mixing after the weighing or do mixed, till mixing with each component, if adopt wet mixing then to mix to finish slip is carried out drying, in the saggar of afterwards mixed powder being packed into, it is synthetic to carry out high-temperature calcination, firing temperature is 1280～1400 ℃, and soaking time 5～10 hours is put into high temperature synthetic powder in the ball mill and to be ground, be ground to below the 5 μ m, carry out drying and make powder body material of the present invention.
Powder body material of the present invention is added binding agent,, carry out coating preparation, or adopt the method for thermospray to spray to matrix surface to form required coating, be used for lasing safety and laser camouflage as acrylic resin, silicone resin etc.After testing, powder body material of the present invention has the characteristics to 1.06 μ m and 10.6 μ m laser high-absorbilities (〉=93%) and antiradar reflectivity (≤8%) that general ceramic powder does not have, and satisfies the laser camouflage requirement.
