Description
Technical field
The present invention relates to a kind of cabin plate, be specifically related to the preparation method of the paper honeycomb cabin plate with heat-proof quality.
Background technology
The heat-insulating technique of current paper honeycomb Cabin plate mainly contains two kinds, and a kind of is filling with insulation material in the honeycomb core bore lattice of cabin plate, another kind be cabin plate is designed to foam, two-layer composite that honeycomb combines.
The principle of the first technology is with the volume of air in reduce orifice lattice by filling with insulation material in honeycomb hole lattice, and cut off air and contact with the direct of covering, thus reducing convection current and the radiant heat transfer of air, the heat-barrier material of filling is generally polyurethane foam or glass fibre.In order to ensure the lightweight characteristic of cabin plate, filling thickness generally only has 1/3rd of honeycomb core thickness, and concrete process route is: and honeycomb core, foam core cut → and foam core material is embedded honeycomb core → covering rubber blanket secondary lamination → covering by press, glued membrane, core assembling → hot-press solidifying are shaping.
The principle of the second technology is the compound by froth bed and paper honeycomb layer, makes cabin plate not only have certain rigidity (realizing primarily of keriotheca) but also possess certain heat-insulating property (realizing primarily of polyurethane foam).Concrete process route is: honeycomb core, foam core cut → covering, glued membrane, core assembling → hot-press solidifying are shaping.
Above-mentioned two kinds of heat-insulating techniques are adopted to have following shortcoming:
(1) defect of the first technical scheme is that to inlay the paper honeycomb core bore lattice size of foam sufficiently large, so that honeycomb hole lattice wall cuts foam smoothly, but the paper honeycomb core mechanical property of macropore lattice and thermal resistance performance lower, be difficult to the strength demand and the heat-proof quality that meet the large plate of shelter; In addition to inlay in foam process often pressure comparatively large for honeycomb core, easily occurs the situation of press pressure deficiency or make because pressure is excessive paper honeycomb core cutting edge subside, and then making the adhesive effect in later stage not good; The requirement of foam mosaic technology to foam is higher, density, hardness and inlay position and all have strict requirement, otherwise inlays and easily occur foam compression skinning, the more difficult control of technical process afterwards.
(2) defect of the second technical scheme is because low intensive foam core occupies certain thickness, and the bulk strength therefore when cabin plate gross thickness is certain is on the low side, can not meet the needs of carrying; In addition composite construction complex technical process, the bonding number of plies is more, easily occurs delamination; Add one deck covering, therefore cabin plate heavier-weight due in the middle of interlayer, be difficult to realize light-weighted target.
Summary of the invention
The object of the present invention is to provide a kind of paper honeycomb cabin plate, its when meet lightweight, ensure mechanical property good heat-insulation effect.
Concrete technical scheme of the present invention is as follows:
A preparation method for paper honeycomb cabin plate, comprises the steps:
1) at upper surface or the lower surface rubberizing film of upper covering, at upper surface or the lower surface rubberizing film of lower covering;
2) upper covering is fixed on the bottom surface of cope match-plate pattern, upper covering posts the surface of glued membrane down, is placed on lower bolster by lower covering, and lower covering posts the surface of glued membrane upward;
3) paper honeycomb core is placed on the glued membrane on lower covering, then with jack by cope match-plate pattern and upper Diaphragm-braced above paper honeycomb core, make the distance between the glued membrane on the upper surface of paper honeycomb core and upper covering be 3 ~ 4mm;
4) after said structure entirety being encapsulated, vacuumize, make the vacuum in encapsulation be-65 ~-55KPa;
5) then by pressure release jack, cope match-plate pattern and upper covering are fallen;
6) by hot-forming to upper covering, lower covering and honeycomb core;
7) dismantle cope match-plate pattern and jack, namely obtain paper honeycomb cabin plate.
Distance between glued membrane on the upper surface of paper honeycomb core and upper covering is set to 3 ~ 4mm, and after jack release, under negative pressure of vacuum effect, covering, glued membrane can fit tightly with honeycomb core, keep the vacuum inside paper honeycomb core.
Upper covering and lower covering, before rubberizing film, are polished to its surface, are oxidized, cleaning treatment; The glued membrane of covering or lower skin-surface can not be come off from upper covering or lower covering, significantly improve the bonding force between glued membrane and upper covering or lower covering.
Hot pressing pressure in step 6) is 0.8 ~ 0.9MPa, and hot pressing temperature is 110 DEG C ~ 120 DEG C, and hot pressing time is 2 ~ 2.5 hours.
Encapsulation in step 4) adopts vacuum diaphragm, and vacuum diaphragm is provided with connector, and vavuum pump is connected with the connector of vacuum diaphragm.
Method for packing in step 4) is: vacuum diaphragm is covered total.
Method for packing in step 4) is: vacuum diaphragm is wrapped up total.
The hole lattice length of side of described paper honeycomb core is 2.75 ~ 5.5mm.
Described jack is connected with hydraulic hand-pump by pipeline.
Described jack comprises 6, and described pipeline comprises house steward and is in charge of, and house steward is connected with hydraulic hand-pump, is in charge of and is connected with each jack; Said structure is adopted hydraulic hand-pump and 6 jack to be connected as a single entity, release hydraulic hand-pump gets final product release 6 jack, easy to operate, manually hydraulic pump can well ensure the synchronism of each jack, after jack release, under negative pressure of vacuum effect, covering, glued membrane can fit tightly with paper honeycomb core.
The present invention, in the process preparing paper honeycomb cabin plate, carries out vacuum pumping to honeycomb core bore lattice; Place mat glued membrane is needed according between bonding requirements honeycomb core and upper and lower covering, if technical process conveniently vacuumizes after upper and lower covering, glued membrane, honeycomb core assembling, can cram honeycomb hole lattice under negative pressure because glued membrane is softer, the action therefore vacuumized will be difficult to carry out.And use special tooling of the present invention that honeycomb hole lattice are taken out in process processed in vacuum to keep opening wide, again by paper honeycomb core and glued membrane, upper and lower covering curing molding after the vacuum system of taking out completes.Honeycomb core bore lattice are vacuumized, greatly reduces because the convection current, radiation, conduction etc. of air is conducted heat in honeycomb hole lattice, significantly improve the heat-proof quality of cellular board.
