Preferably, the panel is 7 line aluminium alloys.
The present invention also provides a kind of applications of above-mentioned high-strength sound insulation foam aluminium glue knot battenboard, and the battenboard is answered In the carriage for using bullet train or automobile, the high intensity having is able to satisfy the intensity requirement of bullet train or automobile body plate, And its sound insulation property having can provide occupant comfort quietly ride environment, avoid the influence of extraneous noisy environment.
Compared with prior art, the present invention has following technical effect that
Battenboard provided by the invention adequately utilizes foamed aluminium board institute by the way that panel is arranged in the two sides of foamed aluminium board The sound insulation property that has and high-intensitive feature, also, the panels of foamed aluminium board two sides also intensity with higher is overlayed on, it solves Acoustic loss caused by open-work and crack, achievees the effect that further to completely cut off sound wave in foamed aluminium board.
The adhesive layer has excellent mechanical performance and bond effect, and foamed aluminium board and panel are bonded as one knot Structure.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment.
Detailed description of the invention
Fig. 1 is the schematic diagram of the battenboard provided in embodiment 1；
Fig. 2 is the schematic diagram of the battenboard provided in embodiment 4；
Figure label explanation: 10- foamed aluminium board, 11- through-hole one, 20- panel, 21- through-hole two, 30- adhesive layer.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below Specific accompanying drawings and embodiments are closed, the present invention is furture elucidated.
As shown in connection with fig. 1, the present invention provides a kind of high-strength sound insulation foam aluminium glue knot battenboard, including foamed aluminium board 10 and The panel 20 of 10 two sides of foamed aluminium board is set, is provided with adhesive layer 30 between the panel 20 and foamed aluminium board 10；
The adhesive layer includes that the raw material of following parts by weight is prepared: 72~100 parts of polyether polyol, diisocyanate 65~90 parts of ester, 25~40 parts of acrylic acid, 12~20 parts of hydroxy-ethyl acrylate, 1~5 part of inorganic reinforcing fiber, emulsifier 5~15 Part, 0.5~2 part of curing agent, 0.1~1 part of diluent, 150~200 parts of water.
In the present invention, using foamed aluminium board as core plate, panel is set in its two sides, is contained in the foamed aluminium board abundant Pore structure, have good sound insulation sound absorption effect.
In the adhesive layer, with diisocyanate recombination reaction can occur for polyether polyol, generate polyurethane resin；Add After entering acrylic resin, the hydrophilic radical Tong Shui, the affinity of cream on polyurethane macromolecular chain are larger, the same water of acrylic monomers, The affinity of cream is smaller, therefore being formed by shell, polyacrylic resin of polyurethane resin is the colloform of stratum nucleare；Described Crosslinking copolymerization between nucleocapsid can occur when the free radical acrylate of core causes and polymerize for hydroxy-ethyl acrylate, to form nucleocapsid The structure of crosslinking, polyurethane resin and polyacrylic resin in the structure compensate for respective deficiency, the adhesive layer tool of formation There are better mechanical strength and weather resistance；
The inorganic reinforcing fiber is interspersed in core-shell crosslink structure, mechanical strength and weather resistance tool to adhesive layer Have significant improvement.
Further, according to the present invention, the polyether polyol can not only react generation with diisocyanate Polyurethane resin can also react with acrylic acid and generate acrylate；The polyether polyol is polypropylene oxide two At least one of alcohol, polytetrahydrofuran diol, tetrahydrofuran-propylene oxide copolymer glycols, polypropylene oxide triol.
Further, according to the present invention, the diisocyanate is toluene di-isocyanate(TDI), two isocyanide of diphenyl methane At least one of acid esters, lysine diisocyanate, isophorone diisocyanate, hexamethylene diisocyanate.
In the present invention, it is brilliant that the inorganic reinforcing fiber is selected from glass fibre, alumina whisker, magnesia crystal whisker, zirconium oxide At least one of palpus, chromium oxide whisker, silica whisker.
In the present invention, the curing agent be in carboxyethyl ethylenediamine or dimethylformamide, thiocarbamide triethylene tetramine extremely Few one kind.
The diluent is butyl glycidyl ether, in ethyl acetate, dimethylformamide, dibutyl phthalate It is at least one.
In the present invention, the emulsifier is one or two kinds of in octyl phenol polyoxyethylene ether emulsifier op-4 or OP-10.
In the present invention, the realization for the sound absorption effect that insulates against sound mainly has benefited from foamed aluminium board, and sound wave enters the hole of foamed aluminium board In structure, cause the vibration of air in hole, then metal panel vibration, a metal structure of an essay mutually restrains, and vibration is obstructed and is converted For thermal energy.According to the difference of pore structure, foamed aluminium board is divided into through-hole structure and two kinds of hole-closing structure, in the present invention, preferably adopts With the foamed aluminium board of hole-closing structure, the foamed aluminium board with a thickness of 8~15mm, density is 0.35~0.50g/cm3.In order into One step reduces the influence of open-work and crack for sound insulation property in closed-cell foam aluminium sheet, and panel is arranged in the two sides of foamed aluminium board, Pass through acoustic loss caused by open-work in panel solution foamed aluminium board and crack.
In the present invention, the panel is 7 line aluminium alloys, and 7 line aluminium alloys are mainly Al-Zn-Mg-Cu alloy, Representative is 7075 aluminium alloys, has the characteristics that high rigidity, high intensity, resistance to corrosion are strong, is disposed at the two of aluminium alloy plate Side, to significantly improve the intensity of the sound insulationg board, resistance to corrosion.
In the present invention, foamed aluminium board and 7 line aluminium alloys are bonded together by adhesive layer, in the same of sound absorption that ensure to insulate against sound When, have the characteristics that high rigidity, high intensity, resistance to corrosion are strong, the battenboard of formation can be suitably used for bullet train and automobile The noise of bullet train or automobile external can be effectively isolated in boxboard, build quiet environment of comfortably riding；Also, institute The aluminium alloy plate stated also has the characteristics that lightweight, for reducing the self weight of bullet train and automobile, improves fuel efficiency.
