Abstract
The utility model relates to a ply bamboo that carriage board was used, the panel that includes the base plate and have the fire prevention function, the air discharge duct to the indent that has a perfect understanding is with great ease offered to the substrate surface, the air discharge duct is in the position between base plate and the panel, the base plate includes well plywood and both ends board, the base plate lower surface is equipped with the draw -in groove, be provided with the strengthening rib in the draw -in groove, the panel top layer is equipped with the mixed acid and alkali resistance coating of a layer of polyurethane resin, owing to offer the air discharge duct to the indent that has a perfect understanding with great ease at the substrate surface, when ambient temperature risees, in the vaporization moisture content that releases in the base plate will get into the air discharge duct along wooden fiber direction, because the air discharge duct is arranged in the middle of the surrounding air, lay down interior pressure with this, reach and solve the come unglued mesh of tympanic bulla of the panel that has the fire prevention function, reduce the loss, and economic benefit can be improved as well, the both ends board adopts the fibreboard, crack control fibreboard adhesive strength is higher than bamboo chip adhesive strength, the fixed fracture that is difficult to of messenger carriage board that can be better.
Description
Technical field
This practicality relates to field, compartment, particularly relates to a kind of bamboo plywood of compartment board.
Background technology
Current domestic passengers' railway car plate material generally selects the substrate be made up of multi-plywood and the panel with fire-proof function to form, a kind of carriage plate of the outer thick china of substrate surface, this kind of railway carriage or compartment plate can be used as a wallboard, wallboard, the inner decoration materials such as ribbon board, rubberizing form is adopted between panel and substrate, one of glue kind is solvent-borne type contact glue, its resin application methods is for brushing, blade coating, spraying, substrate and panel double spread, airing certain hour after gluing, be bonded together and apply certain pressure after solvent volatilization and make it to cement, because multi-plywood is in production, transport.Store and moisture content in surrounding environment can be absorbed in work progress, along with the operation of passenger train, panel facing ambient temperature, humidity is all in generation constantly change, when environment temperature raises, substrate internal moisture will be vaporized and be discharged, and to be collected between substrate and panel in glue-line gap, constantly increase along with temperature raises the vaporize water dosis refracta gathered, the interior pressure produced also constantly increases, when interior pressure is increased to the engaging force being greater than glue, namely PLASTIC LAMINATED jack-up is produced the phenomenon of the bubbling that comes unglued by the interior pressure that vaporization moisture produces, repair or change the manpower that bubbling railway carriage or compartment plate drops into that comes unglued, material resources are all very large, also to there is intensity low for existing railway carriage or compartment plate in addition, the problem that corrosion resistance ability is low.
Utility model content
In order to solve the technical problem of above-mentioned existence, the utility model provides a kind of bamboo plywood of compartment board, and concrete technical scheme is:
A kind of bamboo plywood of compartment board, it is characterized in that: comprise substrate and the panel with fire-proof function, the outer thick china of described substrate surface, described substrate surface offers the air discharge duct concaved through in length and breadth, described air discharge duct is in the position between substrate and panel, the degree of depth that described air discharge duct concaves is 3 millimeters, bottom width is 3 millimeters, described substrate comprises la m and two end plates, described la m and panel are made up of one or the bamboo mat of more than that overlaps together, described bamboo mat knits structure by the seat that bamboo chip is crisscross, described bamboo mat is oblique volume or the vertical woven structure of picking up two signatures two, described two end plates is fiberboard, described base lower surface is provided with draw-in groove, reinforcement is provided with in described draw-in groove, described panel top layer is provided with one deck polyurethane resin mixing acid-fast alkali-proof coating.
The compared with prior art acquired technique effect of the utility model is: owing to offering the air discharge duct concaved through in length and breadth at substrate surface, when environment temperature raises, the vaporization moisture content discharged in substrate will enter in air discharge duct along direction of wooden fibers, because air discharge duct is discharged in the middle of surrounding air, with this, interior pressure is laid down, reach and solve the panel with fire-proof function and to come unglued the object of bubbling, reduce the loss, increase economic efficiency, two end plates adopts fiberboard, defend and split fibre plate bonding strength is higher than bamboo chip bonding strength, compartment board can be better made fixedly to be not easy cracking, base lower surface is provided with reinforcement, make compartment board more firmly firm, panel surface is provided with one deck polyurethane resin mixing acid-fast alkali-proof coating, there is antisepsis.
Accompanying drawing explanation
Fig. 1 is the bamboo plywood structural representation front view of the utility model compartment board.
Fig. 2 is the bamboo plywood structural representation top view of the utility model compartment board.
Detailed description of the invention
Below in conjunction with accompanying drawing 1,2, the utility model is described.
Fig. 1, the bamboo plywood of a kind of compartment board shown in Fig. 2, comprise substrate 1 and the panel 2 with fire-proof function, the outer thick china 2 in described substrate 1 surface, described substrate 1 surface offers the air discharge duct 3 concaved through in length and breadth, described air discharge duct 3 is in the position between substrate 1 and panel 2, the degree of depth that described air discharge duct 3 concaves is 3 millimeters, bottom width is 3 millimeters, described substrate 1 comprises la m 4 and two end plates 5, described la m 4 and panel 2 are made up of one or the bamboo mat 6 of more than that overlaps together, described bamboo mat 6 knits structure by the seat that bamboo chip 7 is crisscross, described bamboo mat 6 is for picking up oblique volume or the vertical woven structure of two signatures two, described two end plates 5 is fiberboard, described substrate 1 lower surface is provided with draw-in groove 8, reinforcement 9 is provided with in described draw-in groove 8, described panel 2 top layer is provided with one deck polyurethane resin mixing acid-fast alkali-proof coating 10.
Owing to offering the air discharge duct concaved through in length and breadth at substrate surface, when environment temperature raises, the vaporization moisture content discharged in substrate will enter in air discharge duct along direction of wooden fibers, because air discharge duct is discharged in the middle of surrounding air, with this, interior pressure is laid down, reach and solve the panel with fire-proof function and to come unglued the object of bubbling, reduce the loss, increase economic efficiency, two end plates adopts fiberboard, defend and split fibre plate bonding strength is higher than bamboo flooring bonding strength, can better make bamboo chip fixedly be not easy cracking.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
