Honeycomb has the regularly arranged of prismatic hexagon hole, can disperse to bear the external force from each side, make honeycomb more much higher than any circle or square to the opposing of pressure, even very slim material, as long as it is made honeycomb shape, just can bear very large pressure.Be subject to just the inspiration of honeycomb, the cellular material of metal, polymer, pottery, papery emerges already.They have diversified application, the Aeronautics and Astronautics parts from cheap building and ornament materials, packaging material to the advanced person, and purposes is very extensive.At present, bonding, stretching according to certain rules forms most honeycomb core by number lamellar material.Difference of the present invention is to utilize the thermoplasticity of textile waste, directly is manufactured with the tack wave-shape board of honeycomb feature with textile waste, then with bonding, the cutting according to certain rules of several layers of wave-shape board, obtains honeycomb core.The present invention both had been conducive to the recycling of textile waste, had also shortened the technique that textile waste is made honeycomb core.
Summary of the invention
Method with the laminated making honeycomb core of textile waste hot pressing can be divided into two parts, and textile waste is made laminated, the cutting of tack wave-shape board and wave-shape board, and concrete technology is as follows:
(1) textile waste is made the tack wave-shape board: at first textile waste is passed through cutting, shredding, be reduced into the reprocessing fiber, wherein the thermoplasticity textile waste fully mixes in proportion with common textile waste; Prepare fleece with the reprocessing fiber that obtains; To fleece preheating, the mold pressing, cooling of preparation, make the tack wave fiberboard of honeycomb feature.
(2) the laminated and cutting of wave-shape board: at first in the crest place of tack wave-shape board coating adhesive tape, then the tack wave-shape board is bonded together from level to level, mode is that the crest of the trough of upper strata tack wave-shape board and adjacent lower floor tack wave-shape board is bonding, obtains the wave-shape board lamilated body; According to the requirement height of honeycomb core, in the cross section cutting of wave-shape board lamilated body, obtain honeycomb core.
The present invention has following outstanding effect:
(1) can utilize the hard textile waste of inferior quality, honeycomb core does not have too high request to outward appearance, need not the different fibers in textile waste are distinguished, and need not textile waste is decoloured;
(2) use the hot forming method, honeycomb core structures is accurate;
(3) only need once heating, thermal energy consumption is few;
(4) relatively laminated, pulling method, manufacture craft is short.
