Description
Technical field
The present invention relates to the coated material preparation method of the heat insulation wave transparent demand of a kind of antenna that can be used for electronics, space flight industry, radome, wave transparent cover.
Background technology
High-speed aircraft during hypersonic flight, is subject to the strong compression of air and friction in atmospheric layer, by most of kinetic transformation, be heat energy, cause the ambient air temperature sharply to raise, and heat energy is rapidly to the aircraft surface transmission.This due to object in the heating phenomena that atmospheric layer high speed flight produces, be called " Aerodynamic Heating ".Along with the increase of flight Mach number, Aerodynamic Heating will be got over seriously, and the air themperature of stagnation region is with the increase that square is directly proportional of Mach number.When surpassing 200 ℃, the aluminium alloy of vehicle construction material and antenna carrier also can't bear high like this thermal load.Therefore, must take the solar heat protection provision for thermal insulation, to prevent the loss of aluminium alloy structure strength and stiffness under hot conditions, guarantee simultaneously plant and instrument normal operation in cabin, improve flight reliability.When supersonic vehicle flies in atmosphere with higher Mach number, surface temperature will reach 350 ℃～600 ℃.Antenna is by conformal with radome and carrier, even antenna itself is conformal with carrier, the thermal conduction of carrier raises the antenna self-temperature in a large number, the antenna temperature distortion causes precise decreasing, causing antenna electric performance to descend even lost efficacy, the high temperature of several Baidu of antenna tolerance simultaneously, heat passes to antenna bottom and high-frequency socket part very soon, causes the plant and instrument of rear end to lose efficacy.In this temperature range, organic coating can not bear, and can occur to decompose to lose heat-blocking action, decomposes simultaneously and can produce uncombined carbon, and the wave transparent rate is acutely descended; And traditional low density ablative-insulative material can not play a role owing in this temperature range, melting filler, therefore also there is no obvious solar heat protection effect of heat insulation, and forms the wave penetrate capability that uncombined carbon affects radome after ablation.For solving the thermal protection problem in this specified temp interval, must seek a kind of new approach.Employing possesses one of effective means that half inorganicization coating of heat insulation and wave penetrate capability addresses this problem beyond doubt.
With the organism of siliceous, carbon, nitrogen, boron, pioneering, to make stupalith be the new discipline that develops rapidly over past ten years to system.It has changed only makes the situation of ceramic raw material traditionally with inorganics, and, because the variety of organic products makes synthetic new ceramic material with set structure and composition become possibility, also make polymer science expand a frontier take Preceramic Polymers as research object simultaneously.The ceramic precursor material is a class organic polymer that synthesizes by chemical process, and it can cracking occur in certain temperature range, is converted into amorphous or xln is ceramic.Vowed that the island sage made to wait the people to utilize poly-carbon silicon a heatable brick bed (PCS) in 1975, successfully prepare the SiC ceramic fiber, opened up the frontier that organic precursor method transforms to inorganic ceramic.
Heat insulation wave transparent coating commonly used comprises glass coating, ceramic coating, high temperature resistant organic coating etc. at present.The advantage of glass coating is that temperature tolerance is good, easily meet the temperature tolerance requirement, and has good wave penetrate capability, thermal conductivity is also lower, has heat-proof quality preferably, but in preparing the glass coating process, all need device is carried out to pyroprocessing, temperature, generally higher than 800 ℃, easily makes the radome matrix decompose, or antenna is deformed or other disadvantageous effects.The ceramic coating making method has precursor conversion method and chemical Vapor deposition process.Precursor transforms the novel process that (PIP) method is the preparation Continuous Fiber Reinforced Ceramic Matrix Composites (CFRCMCs) that grew up in recent years, its primary process is: with precursor solution or liquation impregnation of fibers prefabricated component, dry or curing under certain condition, then Pintsch process, repeated impregnations-cracking process namely obtains fibre reinforced composites for several times.The technological process of precursor conversion (PIP) legal system making coatings is similar with the technological process of preparation Continuous Fiber Reinforced Ceramic Matrix Composites.But precursor has micro-molecular gas and overflows in the ceramic process, therefore mass loss occurs and causes volumetric shrinkage, makes in coating to produce hole and defects i.e.cracks, has influence on integrity and the bonding strength of coating.
Chemical vapour depositionMethod is traditional technology for preparing film, and its principle is to utilize pioneer's reactant of gaseous state, by atom, intermolecular chemical reaction, makes gaseous state
PresomaIn some compositions decompose, and
Base BodyUpper formation film.
Chemical vapour depositionComprise aumospheric pressure cvd,
Plasma bodyAuxiliary
Electroless plating, laser assisted electroless plating, metal
Organic compoundDeposition etc.But the thicknesses of layers of deposition is all thinner, can not realize heat insulation requirement.
Traditional glass coating, ceramic coating preparation temperature, all higher than 800 ℃, higher than the making temperature of 800 ℃, can make organic cover body decompose, and make the metal antenna distortion.Organic coating technique is simple, and is high with the bonding strength of cover body or metal antenna, and wave penetrate capability is good, but the general heatproof of traditional organic coating is lower than 400 ℃.The common feature of organic coating is all to contain a large amount of carbons simultaneously, at high temperature decomposes and produces uncombined carbon, and the wave transparent rate is acutely descended.
