Description
Technical field
The present invention relates to a kind of Composite Panels, especially relate to a kind of Lightweight high-strength composite material wallboard and preparation method thereof.
Background technique
Tradition shelter is generally assembled by link by polyurethane laminboard, and its wallboard is generally composited by aluminum alloy exterior skin layer, Steel Skeleton (or aluminium skeleton), polyurethane foam sandwich, aluminum alloy Inner Mongol cortex.Wallboard making method comprises perfusion foam process and technique for sticking two kinds.
Perfusion foam process foams in the enclosed cavity that formed to skeleton and inside and outside skinning layer by polyurethane foam perfusion by high pressure pouring foaming machine, by skeleton, covering tie layer integrally.Perfusion foam process is that when relying on foaming polyurethane material, the bonding force of self carries out bonding, and the adhesive strength of covering and foam is lower.Foamable reaction speed is very fast, in its course of reaction, often cause foam center density lower, partial density near panel is very high, form one deck sclerderm, when panel is subject to very large difference variation, creates between lead-covering and polyurethane sclerderm and shear and peeling force, very easily cause covering delamination.Polyurethane Perfusion foaming liquid is as incomplete mixing in addition, unreacted free isocyano, and running into moisture can cause foamable reaction again, forms uride, and discharges CO
2gas, causes covering local crowning.
Technique for sticking is by abundant for the polyurethane foam of prefabricated foaming slaking ageing treatment, and through the further Post RDBMS of 120 ~ 130 DEG C of high temperature, then by drawing the foam plate sent out is cut shaping, be machined to permissible accuracy, the foam processed is put into metal frame, with adhering components such as coverings after gluing, then temperature-pressure solidified forming in special fixture.Technique for sticking advantage is, foam can not produce second time of foaming, by the flat bubble complete resection under top layer sclerderm and sclerderm in course of working, eliminates the factor had a negative impact to large plate, ensure that core quality, thus obtains more stable large plate quality.
A kind of Stitched lattice composite material sandwich board disclosed in CN 2799229 Y, disclosed in CN 103643762 A a kind of possess stealthy and thermal insulation property sandwich board and production method all adopt technique for sticking, have the following disadvantages: manufacturing procedure is many, the machining accuracies such as foam, covering and skeleton are had higher requirements; Forming equipment precision, automaticity require higher.
The deficiency that the shelter that conventional method makes exists: 1) perfusion and bonding two kinds of techniques are all only applicable to make dull and stereotyped, that size is little flap.2) metal skin adopted exists perishable, and salt spray resistance, humid are poor.3) it is large to there is surface density in the cabin body adopting these two kinds of techniques to make, and load ratio is low.4) traditional shelter is taked wallboard, corner fittings to connect to combine, and sealing is poor, there is joint stress concentrated, fragilely leaks.5) adopt traditional perfusion foaming or bonding formation technique, be not suitable for the cabin body making special shape, because not only inside and outside skinning layer, skeleton shaping difficulty are large, surface, the cabin aesthetic property after making is poor, and weight indicator far exceedes the requirement of technical order.
