Description
Technical Field
The invention relates to a film-pasting camouflage material, in particular to an ultrathin flexible film-pasting camouflage material and a preparation method and application thereof.
Background
The false target is made of light and cheap materials such as air cushions, foams, wood, plastics and the like to be prepared into a model of real weapon equipment and work, so that the effect of distinguishing true from false or showing false from false is achieved. The false camouflage target objects of military engineering comprise false roads, false workers, false trenches, false bridges, false cave depots, false places, false hangars, false runways, false armholes, wharves and the like. Because the corresponding military true targets and military facilities are mainly made of various metal materials and have strong reflection and echo signal characteristics on incident radar detection waves, the false targets are required to have consistent geometric dimensions and colors with the true targets and also need to have radar reflection characteristic signals for simulating the true targets, namely the surfaces of the false targets must have the function of reflecting electromagnetic waves; in addition, the fake target is required to be light in weight, convenient to transport, erect and withdraw, low in production cost and convenient to maintain. Although the existing metal film has strong reflection effect on electromagnetic waves and is thin in thickness, if the metal film is wrapped on the surface of a false target, the problems of low strength, easiness in damage, single color and the like are generated, and the multi-occasion requirements of modern war cannot be met.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects in the prior art and provide the ultrathin flexible film-pasting camouflage material which can simulate the signal characteristics of military real targets on radar waves and visible light, and has the advantages of low production cost, light weight, high strength, good flexibility, rich colors and wide application range.
The invention further aims to solve the technical problem of providing a preparation method of the ultrathin flexible film-pasting camouflage material.
The technical scheme for solving the technical problem is that the ultrathin flexible film camouflage material is prepared by preparing liquid slurry from two-dimensional flaky conductive powder, colored pigment, functional auxiliary agent, high-molecular thermoplastic rubber and organic solvent, coating the liquid slurry on a plastic film and carrying out hot pressing.
Further, the two-dimensional flaky conductive powder is one or more of micron-sized flaky nickel powder, micron-sized flaky aluminum powder, micron-sized flaky copper powder and micron-sized flaky graphite powder; the addition amount is 55-75% of the total mass of the raw materials, the flaky metal and graphite powder are oriented and arranged when the film is prepared, and the radar wave reflection signals are the same as those of the metal.
Further, the colored pigment is an inorganic pigment and is one or more of titanium dioxide, ferric oxide, carbon black, lead chrome yellow and iron blue, and the particle size of the pigment is larger than 1000 meshes; the addition amount is 5-15% of the total mass of the raw materials.
Further, the functional auxiliary agent is a solvent type auxiliary agent and is one or more of a wetting agent, a dispersing agent, a flatting agent, a vulcanizing agent, a defoaming agent, an antirust agent, a thickening agent and a toughening agent; the addition amount is 2-5% of the total mass of the raw materials.
Further, the high-molecular thermoplastic rubber is one or more of polyurethane rubber, nitrile rubber, ethylene propylene diene monomer, polyolefin rubber, polypropylene rubber and polyvinyl chloride rubber elastomer; the addition amount is 8-20% of the total mass of the raw materials.
Further, the organic solvent is one or more of toluene, xylene, n-butanol, cyclohexanone, toluene cyclohexanone, acetone and ethyl acetate; the addition amount is 15-30% of the total mass of the raw materials.
The invention further solves the technical problem by adopting the technical scheme that the preparation method of the ultrathin flexible film-pasting camouflage material comprises the following steps:
(1) preparing coating slurry: thermoplastic rubber particles, colored pigment, organic solvent and functional auxiliary agent
Uniformly mixing the powder with flaky conductive powder to obtain coating slurry;
(2) coating: coating the coating slurry obtained in the step (1) on a plastic film containing silicon oil to form a wet film and drying to obtain a coating film;
(3) hot-pressing and vulcanizing: carrying out hot-pressing vulcanization treatment on the coating film obtained in the step (2) to obtain a densified thin film;
(4) back gluing: and (4) carrying out gum treatment on the densified film obtained in the step (3) to obtain the ultrathin flexible film-pasting camouflage material. And then the ultrathin flexible film-pasting camouflage material is cut into ultrathin flexible film-pasting camouflage materials with different sizes according to the actual application requirements.
Further, in the step (2), the distance between the scrapers used for coating is 0-0.5 mm, the linear speed is 0.2-1.0 m/min, and the coating is uneven and easy to crack due to the fact that the linear speed is too high; the drying temperature is 50-90 ℃. Too high drying temperature can lead to diaphragm fracture, and too low can reduce work efficiency.
Further, in the step (2), the plastic film is a PET plastic film, and the PET film is used for conveniently uncovering the film.
Further, in the step (3), the working temperature of the roller during vulcanization hot pressing is 100-150 ℃, the proper temperature can soften and plasticize the resin, and the roller is stuck when the temperature is too high; the pressure between the steel belt and the roller is 5-15 MPa, and the steel belt can be damaged due to the fact that the pressure between the steel belt and the roller is too high; the linear velocity is 0.2 to 0.8 m/min. Too fast a speed will result in non-uniform thickness of the formed part.
The ultrathin flexible film camouflage material is applied to fake target simulation on radar wave reflection and visible light characteristic signals, and has a special effect of 'false and false'.
Compared with the prior art, the invention has the following beneficial effects:
(1) the ultrathin flexible film-pasting camouflage material has high conductivity, and can simulate strong reflection characteristic signals of a real target metal material to an incident radar; meanwhile, the appearance color of the film camouflage material can be adjusted according to the added pigment, so that military decoy targets have stronger fake camouflage effect.
(2) The film-pasting camouflage material has the advantages of high strength, light weight, adjustable size, flexibility, capability of meeting the requirements of various curved surfaces of the actual false target, folding during use, easiness in transportation, installation and withdrawal and stronger actual applicability.
(3) The preparation method can realize continuous batch preparation, has high production efficiency and low cost, and is very beneficial to industrial application.
