Frame structural material (such as pyramid structure, tetrahedral structure).
At present, dot matrix metal sandwich plate due to its own structure d amping coefficient it is smaller, it is necessary to passing through composite construction improves it
A kind of vibration and noise reducing performance, existing frame mode is embedding damping resin material in the core, but can cause overall structure matter
Amount a larger increase, the composite construction mode that the occasion strict for Weight control needs searching new further realizes loss of weight requirement.
Standard aqueous damping paint not only has antiseptic property, and with the higher losses factor, maximum can reach 1, its relative to
The fissipation factor of common metal has been higher by several magnitudes.Acrylic resin-based damping coatings, shape are applied by core body inner surface
Into composite construction, it is possible to achieve lightweight, high intensity high rigidity, vibration and noise reducing multifunctional all design requirement.
The content of the invention
The technical problems to be solved by the invention are for above-mentioned deficiency of the prior art, there is provided one kind combination dot matrix
The respective advantage of sandwich and acrylic resin base damping material, realizes that respective functionality advantage is integrated by way of compound,
Realize various function fusions dot matrix metal-resin base damping coatings composite and preparation method thereof.
The present invention uses following technical scheme：
A kind of dot matrix metal-acrylic resin-based damping coatings composite construction preparation method, comprises the following steps：
S1, the lattice core that ordered porous structural is prepared using molding or folding, then by panel and dot matrix core
Body goes to degrease and rusty stain using metal cleaner cleaning, using soldering, Laser Welding or epoxy glue adhesive bonding technique by the panel
A gust metallic sandwich sheet is made with lattice core connection；
S2, the outside stickup layer of polyethylene diaphragm in panel described in step S1；
S3, under room temperature environment, thick component A is stirred in advance, by crosslinking agent/damping filler B component by weight
Amount compares A：B=3~5:1 be added in the component A stirred with mixer it is standby；
In S4, the lattice structure metallic sandwich sheet immersion step S3 for preparing step S1~S2 deployed solution,
Dipping 5~60 seconds, forms the Aanalysis of Film-damping layer of uniform coating, and 10~20 minutes are stood in 50 DEG C~60 DEG C baking ovens；
S5, step S4 repeat 2~6 damping layers 3 of formation different-thickness, then are stood in 50 DEG C~60 DEG C baking ovens
2~5h is stored at room temperature 12~24 hours, removes polyethylene protective film, obtains dot matrix metal-acrylic resin-based damping
Coated composite structure.
Further, in step S1, the lattice core includes pyramid structure and ripple struction.
Further, in step S1, the material of the metallic sandwich sheet includes carbon steel, stainless steel, fine aluminium, aluminium alloy, titanium
Alloy or nickel alloy.
Further, the metallic sandwich sheet of carbon steel material, need to be on the inner side of the panel and the surface of lattice core
The epoxies anti-corrosive primer of 0.1~0.2mm of spraying a layer thickness.
Further, the relative density of the lattice core is 0.01~0.15.
Further, in step S3, the component A is water-based acrylic resin damping material, and the B component is titanium white
Powder, diatomite, aluminum oxide and calcium carbonate material.
Further, the average grain diameter of the B component is 40~70 microns.
Further, in step S4, the lattice structure metallic sandwich sheet is at the uniform velocity lifted, equably sagging exists to make solution
The panel inner side and the surface of lattice core.
Further, the thickness of the damping layer for ultimately forming is 0.2~2mm.
A kind of dot matrix metal-acrylic resin-based damping coatings composite construction, the composite construction is by lattice core and panel
The dot matrix metal sandwich plate composition being made, uniformly one layer of damping layer is coated with the panel inner side and the lattice core.
Compared with prior art, the present invention at least has the advantages that：
The present invention prepares the lattice core of ordered porous structural using molding or folding first, then by panel and
Lattice core goes to degrease and rusty stain using metal cleaner cleaning, using soldering, Laser Welding or epoxy glue adhesive bonding technique by institute
State panel 1 and the connection of the lattice core 2 is made a gust metallic sandwich sheet, then paste layer of polyethylene protection in the outside of panel
Film；Under room temperature environment, thick component A is stirred in advance, by crosslinking agent/damping filler B component by weight A：B=
3~5:1 be added in the component A stirred with mixer it is standby；Lattice structure metallic sandwich sheet is immersed again is adjusted
In the solution for preparing, impregnate 5~60 seconds, form the Aanalysis of Film-damping layer of uniform coating, stand 10 in 50 DEG C~60 DEG C baking ovens~
20 minutes；2~6 damping layers of formation different-thickness are repeated, then 2~5h or room are stood in 50 DEG C~60 DEG C baking ovens
Temperature stands 12~24 hours, removes polyethylene protective film, obtains dot matrix metal-acrylic resin-based damping coatings composite junction
Structure, by acrylic resin damping paint even application to dot matrix metal sandwich (ripple struction and pyramid structure) inner surface
Metal lattice-acrylic resin base damping material is obtained, multi-functional compound, the more excellent structure of acquisition combination property is realized
Function integration material, is suitable in the engineering field application such as communications and transportation, building, space flight and aviation.
Further, truss core structure (pyramid structure and ripple struction) is a kind of porous knot of excellent in mechanical performance
Structure, this structure type similar to existing space net rack, with ultralight, specific stiffness it is high, specific strength is big, controllable optimization design
The multifunctionality such as ability and heat-insulated, energy-absorbing.
Further, easily there is corrosion in carbon steel material, and metallic sandwich sheet surface spraying epoxies anti-corrosive primer can be fine
Ground suppresses carbon steel material and corrosion occurs, and damping coatings is had preferable bonding force with metal, prevents damping coatings from coming off.
Further, the present invention subtracting using the excellent mechanical property of dot matrix metal and acrylic resin base damping material
Shake the respective advantage of noise reduction, structure under vibration, due to the excellent viscoelastic property of acrylic resin base damping material, resistance
Damping material produces certain deformation under external force, but its deformation lags behind stress, due to this hysteresis so that high polymer
Stretching retraction circulation change need to overcome the intersegmental frictional resistance of chain, the interior friction for producing is moved by a large amount of outfields by molecule segment
Energy of the effect as mechanical oscillation, acoustic vibration are produced is converted into thermal dissipation so as to reach the mesh of vibration and noise reducing, acquisition it is compound
Structure not only has compared with high damping properties (fissipation factor 0.2~0.3), and the further lightweight of structure, improves structure
Quality efficiency (relative to epoxy resin filling metal lattice composite construction).
