Problems solved by technology

[0004] In the prior art, there are also special stealths for far-infrared, but most of them use aluminum powder, which is difficult to mix into the paint.
Aluminum powder has a good protective effect, but it is easy to oxidize
There is also the use of rare earth elements to achieve this effect, but due to the high price of rare earth elements, it is difficult to adopt them on a large scale

Embodiment 1

[0036] Embodiment 1: described front coating is by mass percent: polyurethane PU resin 55%

[0037] Cobalt-based inorganic pigments 20%

[0038] Hollow glass microsphere 70μm 25%

[0039] mixed; its reverse coating consists of mass percent

[0040] Polyurethane PU resin 55%

[0041] Cobalt-based inorganic pigments 10%

[0042] Hollow glass microsphere 70μm 20%

[0043] 15% microcapsule phase change material mixed;

[0044] Wherein the thickness of the front paint is 1.5 times of the reverse paint. During processing, the carrier cloth is scraped and coated by the coating machine. The carrier cloth is made of polyethylene with a thickness of 0.20 mm, and the thickness of the scraper is 3.0 mm. Scrape coating at 20 m / min, and then scrape coating on the reverse side after drying, so that the coating on the carrier cloth has a certain thickness and the coating surface is uniform. In this case, a thinner blade is used for rapid multiple strokes due to the thinner substrate. ...

Abstract

The invention provides double-side coating fabric. The far-infrared protection effect is enhanced besides near-infrared can be effectively reflected. Moreover, the whole fabric is reasonable in price and can be popularized on a large scale. According to the double-side coating fabric, paint is prepared by mixing, by mass, 55-70% of polyurethane (PU) resin, 5-20% of cobalt inorganic pigment, 10-25% of 70-micron hollow glass microspheres (200 meshes) and 0-15% of microcapsule phase-change materials. By means of the arrangement, according to the double-side coating fabric, formulas and preparation methods of military coatings are further refined, the requirement of military standard stealth performance of China is met, the coating price is reduced by over 20% compared with similar products with the same effect, and the fabric is suitable for environments at various temperatures and better in compatibility.

Description

technical field [0001] The invention relates to a military fabric, in particular to a double-sided coated fabric. Background technique [0002] Infrared stealth paint refers to the special functional paint used to weaken the signal of the infrared signature of the weapon system. It is mainly aimed at the detection of infrared thermal imaging cameras. The probability. For example, the invention patent "Double-sided camouflage foam structure camouflage stealth tarpaulin material" with the patent number "201110387547.8" in the prior art discloses a double-sided camouflage foam structure camouflage stealth tarpaulin material, which is made of polyurethane foam structure It is made of composite of bile and PVC coated camouflage layer. The invention comprehensively uses the structural wave-absorbing characteristics of soft polyurethane foam materials and the high-quality engineering application performance of PVC-coated camouflage cloth. It has microwave broadband stealth perfor...
