Description
Technical field
The present invention relates to a kind of anti-insulating moulding coating and its preparation method and application, when particularly one kind can be subjected to long, height
Warm, high speed pneumatic thermal ablation anti-insulating moulding coating and preparation method thereof.
Background technology
With the raising of weaponry flying speed, the increase of range and the extension of endoatmosphere flight time, flight
The thermal environment that device is born is increasingly harsh.High temperature, high velocity air souring under, based on ablation consumption mechanism traditional solar heat protection
Coating shows the problems such as coated thread ablation amount is big, ablation shape is coarse, out-of-flatness.The design of another aspect aircraft lighting
Theory, requirements at the higher level are proposed to the anti-thermal efficiency of thermal protective coating.
《Composite is innovated and sustainable development (first volume)》Article《Thermal protective coating FT-22 development and application》
In, discuss experimental condition, test piece model and the wind tunnel test knot of FT-22 thermal protective coating test piece Aerodynamic Heating ablation tests
Fruit." experiment is tested using orbital simulation, and experimental condition is that hot face temperature is 1008 DEG C, time 79s.Test piece model is
Ground is the thick casting magnesium flat boards of 5mm, and coating layer thickness about 3mm, size is 150mm × 150mm, simultaneously coarse through polishing, and uses solvent
Clean up, first spray-applied primer, then spray FT-22 heat-resistant paints." wind tunnel experimental results on FT-22 thermal protective coatings, Wen Zhong
So discuss：" results of wind tunnel can be seen that FT-22 thermal protective coatings after ablation, and hot face temperature is from 1008
DEG C be reduced to 160 DEG C, and surfacing carbonization, crackle occur, without it is any peel off, the phenomenon of pitting corrosion, illustrate that FT-22 prevents
Hot coating has good high temperature resistant heat insulation effect, and the charring layer thermal conductivity that ablation is formed is low, scour resistance is excellent, meets examination
Piece back of the body temperature is less than 250 DEG C of requirement." and table temperature will be more than 1000 DEG C, for up to hundreds of during aircraft high-speed flight of new generation
Second, the design thickness of new model aircraft thermal protective coating is only but 2mm, and pole is proposed to the heat resistance and the anti-thermal efficiency of coating
High request, the heat-resistant paint mentioned in article are the Typical Representatives of traditional heat-resistant paint, can not meet Aero-Space of new generation
The anti-heat demand of product.
The content of the invention
Present invention aims at provide it is a kind of be subjected to long when, high temperature, high speed pneumatic thermal ablation intermediate temperature setting solar heat protection painting
Material and its preparation application method, solve the problems, such as the thermal protection of aircraft and construction technology problem under particular flight environment.
The coating is coated on piece surface, and the combustion gas stream ablation that 2mm thickness can withstand 1000-1200 DEG C is washed away, held
Part back temperature is less than 200 DEG C after continuous 200s, and coating ablated surface is smooth, without any crackle, peel off phenomena such as, very well
The characteristics of embodying sintering dimension shape under the conditions of the coating Aerodynamic Heating and efficiently anti-heat-insulated advantage.
A kind of anti-insulating moulding coating, by Effect of Organosilicon-modified Phenol-formaldehyde Resin, hollow ceramic microspheres (40 μm -100 μm of particle diameter), inclined boron
Sour barium (mesh of 200 mesh of fineness -400), vermiculite power (density 100-350kg/m3), ammonium polyphosphate APP 1000 and organobentonite group
Into its mass ratio is 35~40%：10~12%：10~12%：15~18%：10~15%：8~10%, its side prepared
Method is：
The first step, according to 10~12%：10~12%：15~18%：10~15%：8~10% mass ratio weighs empty
Heart ceramic microsphere (40 μm -100 μm of particle diameter), barium metaborate (mesh of 200 mesh of fineness -400), vermiculite power (density 100-350kg/
m3), five kinds of powders of ammonium polyphosphate APP 1000 and organobentonite；
Second step, five kinds of powders are tentatively mixed and are put into baking more than 4h in 60 DEG C of baking oven；
3rd step, Effect of Organosilicon-modified Phenol-formaldehyde Resin is weighed according to 35~40% mass ratio；
4th step, the powder after drying is added in Effect of Organosilicon-modified Phenol-formaldehyde Resin, it is a small amount of repeatedly to add acetone not
Disconnected stirring is rubbed up to uniform state, and coating semi-finished product are made；
5th step, above-mentioned coating semi-finished product are filtered by 100 mesh sieve, and by the residue remained on sieve, caking etc.
Filter is into coating after grinding；
6th step, add proper amount of acetone and above-mentioned coating is modulated into viscosity as 16~22s (applying -4 glasss of measurements)；
After heat-resistant paint prepares, the coating prepared is sprayed on to the piece surface of cleaning with conventional pneumatic spray gun (can enter
Row sandblasting or grinding process), 0.2~0.4MPa of spray pressure, spray gun and 200~300mm of piece surface distance, every time spraying are thick
Degree 0.1~0.2mm of control, first pass spraying hang 60min after terminating under normal temperature condition, then carry out second time spraying, hang
Sprayed again after 60min, repeat to spray-process is hung, until 2.0 ± 0.2mm of thickness as defined in reaching, finally puts part
Enter baking oven, 4h is toasted under the conditions of 120 DEG C, coating completes curing molding.
The Effect of Organosilicon-modified Phenol-formaldehyde Resin selected in coating, phenolic resin high temperature resistant, the performance advantage of anti-yaw damper are gathered
The mechanical property and weatherability excellent with organic siliconresin, its filler selected by with coating can be in coating surface under pneumatic thermal environment
Dense protective layer is cooperatively formed, the protective layer can effectively stop that the ablation of thermal current is washed away, and absorb the heat of high-temperature particle
Amount, so as to play the thermal protection to bottom material with being thermally isolated.Due to selected resin matrix and a variety of heatproofs, wear resistant filler
Collective effect, heat-resistant paint shaping 2mm thickness can resist High Mach number, high enthalpy (reaching 2000kJ/kg) thermal current environment
Long-time (hundreds of seconds) ablation wash away, for highest table temperature up to thousands of degrees Celsius, ablated surface is smooth, and is not producing
Degrade, ftracture, any ablation problem such as bulge while serve excellent effect of heat insulation.The coating can meet multinomial aviation
The anti-heat demand of space product.
