Problems solved by technology

If phenolic foam is used, it has excellent heat insulation and fireproof performance, but its strength is low; the honeycomb panel made of honeycomb core (paper, metal, ceramic, polymer material honeycomb core, etc.) has high flatness, good rigidity, and light weight, which is very good. Good wall and decoration materials; but the thermal insulation and sound insulation effect of this kind of honeycomb panel is not very good. When doing exterior wall decoration, it needs to add a special insulation layer, which is not economical, takes up space, and is not beautiful. Therefore, using the current honeycomb panel The sound insulation effect is extremely poor when boards are used as interior compartments of houses, ships, and trains

Embodiment 1

[0021] Such as Figure 1-4 Shown, the manufacture method of foam honeycomb core of the present invention mainly comprises the following steps:

[0022] (1) Stretch the regular hexagonal aluminum honeycomb core 1: use manual or stretching machine to draw and shape;

[0023] (2) The size of the foam material 2 is made according to the stretched size of the honeycomb core 1: the length, width, and height are respectively consistent with the honeycomb core 1 or customized according to specific needs. The stretched size of the honeycomb core 1 is 2400mm long , 1200mm wide and 20mm high, the foam is made into 2400mm×1200mm×20mm;

[0024] (3) Flat pressing process: put the honeycomb core 1 and the foam material 2 into the flat press 3 after stacking, and adjust the pressure of the flat press 3 according to the density, hardness, and conditions of the foam. It is advisable that the material 2 is just completely pressed into the honeycomb core 1 without destroying the honeycomb struc...

Embodiment 2

[0027] Such as Figure 1-4 Shown, the manufacture method of foam honeycomb core of the present invention mainly comprises the following steps:

[0028] (1) Aramid paper honeycomb core (0.08mm paper thickness × 8mm side length) can be stretched and heated to shape, and can be sliced ​​after twice dipping and heat curing;

[0029] (2) The size of the foam material 2 is made according to the stretched size of the honeycomb core 1: the length, width, and height are respectively consistent with the honeycomb core 1;

[0030] (3) Flat pressing process: stack the honeycomb core 1 and the foam material 2 and put them into the platform. One side of the platform is flat, and the other side directly applies pressure. The pressure is large enough to press the foam material 2 completely It is advisable not to damage the honeycomb structure in the honeycomb core 1;

[0031] (4) Make a honeycomb panel with the foam honeycomb core 4, apply glue through the glue groove 5 on the back of the t...

Abstract

The invention relates to a method for producing the foam honeycomb core, mainly comprising the following steps: stretching a honeycomb core; producing foaming material according to the size of the stretched honeycomb core; overlapping the honeycomb core and the foaming material; and putting the honeycomb core and the foaming material in to a plate press. The honeycomb core is a hexagonal, polygonal, corrugated or round tube-type honeycomb core which comprises paper, metal, ceramic and polymer material. The foaming material can be phenolic aldehyde, polyphenyl, polyurethane, etc. The invention has the advantages that the foaming material such as the phenolic aldehyde, the polyphenyl, the polyurethane and the like and the prior honeycomb core are overlapped and then are putted in the plate press to be extruded and combined so that the strength of the sandwich of a foam honeycomb plate is improved and the foam honeycomb plate has the advantages of light weight, high planeness and excellent sound insulation effect, fire resistance and heat insulation properties, in addition, the cost of the material is lowered, the foam honeycomb core has the advantages of good machinability, simple structure, good decorating effect and the like, and moreover, the foam honeycomb plate can be produced with the extremely easier and feasible method.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a manufacturing method of a foam honeycomb core. Background technique [0002] Honeycomb panel is a kind of high-grade decoration compounded by metal plate, stone, various fiber composite panels, aluminum-plastic panels, stainless steel panels, fireproof panels, wooden panels and other decorative materials and honeycomb core by polymer adhesive. Its products have the advantages of high flatness, light weight, energy saving, high strength, sound insulation, fire and moisture resistance, corrosion resistance, environmental protection, and convenient installation. They are widely used in aviation, transportation, elevators, purification workshops, partitions, and furniture. , electrical appliances, mechanical equipment, indoor and outdoor and curtain wall decoration; while asbestos, glass wool, expanded perlite and other inorganic insulation materials have excellent fire resistanc...
