Another purpose of the present invention provides makes the technology that this banana is set false stem cortical plate.
At least the banana that comprises two-layer integrated bond according to banana tree pseudobark laminated board provided by the present invention is set false stem cortex, it is transversely arranged and contact with each other with equidirectional that banana is set false stem cortex, and the banana in every layer is set false stem cortex and set false stem cortex perpendicular to the banana of its adjacent the upper and lower.
The present invention also provides a kind of making to be surrounded by the method for two-layer bonding banana tree pseudobark laminated board at least, and its processing step is:
It is transversely arranged in the same direction that many bananas are set false stem cortex, sets false stem thin layer to form banana.
At least it is superimposed that the two-layer banana that is obtained in rapid by previous step is set false stem interlaminate, and making every layer banana set false stem cortex and the adjacent banana that the upper and lower are arranged, to set pseudoderm orthogonal.
The banana that has adhesive is set the superimposed pressurization of false stem cortex.
Pressurization steps is preferably under normal temperature to 120 ℃ temperature and under the pressure at 3-20Kg/cm banana is set false stem cortex and carry out hot pressing in said method.
The invention will be further described with accompanying drawing below:
Figure 1A-1E has illustrated that continuously the present invention produces the method for laminated material.
Fig. 2 is a flow chart, it has represented the production method according to banana tree pseudobark laminated board of the present invention, getting the false cane of the false tree of fresh banana tree at first sets false stem pars intermedia with cutter at banana and splits, cut down by hand then from level to level, cortex under cutting is transported to carries out hot pressing dehydration in the roll squeezer, dehydration back gluing, hot-forming at last.
Manual arrangement
Hot pressing dehydration → gluing → hot roof pressure moulding
Banana after the purchase sets that false stem is at first colded pressing or the hot pressing dehydration.
Figure 1A-1F represents to implement six steps of the present invention.These bananas are set the shape slab that false stem can length not be limit, and preferred length is 100cm, and with reference to Figure 1A, the banana with Len req is set false cane 1 and comprised cortex 2 and newel 3, leaf sheath joint 4.
Banana is set false cane and is half-and-half cut along machine direction with cutter 5 (seeing Figure 1B), from level to level cortex is cut down by hand then and is seen that Fig. 1 C2 is the cortex after cutting out.After this again cortex push rolls press 6 pressurizing and dehydratings, as shown in Fig. 1 D, banana is set false cane 1 and is flattened by roll squeezer 6, sets the constrictor that false stem cortex 2 is formed to form banana.
After this as shown in Fig. 1 E, many constrictors layout parallel to each other to form skim 7, the same direction of epidermis one side direction that compression is done, can obtain uniform bonding strength like this, when arranging constrictor, make between bar not interspace, can make thin layer 7 have bigger density like this.
The one or both sides of thin layer 7 scribble resinoid bond, the thin layer 7 that scribbles binding agent is stacked, then with pressure sintering with thin layer bonding-rise.Final laminated material 8 is shown among Fig. 1 F.
After the formation banana is set false stem cortex lamina, with two-layer or multilayer is like that alternately superimposed shown in Fig. 1 E, before superimposed or when just superimposed, the one or both sides of layer 1,2 are coated synthetic adhesive, preferably adopt resin binder, resinoid, cold setting cement.Heat cured adhesive example has phenolic resins, melamine resin, the full resin of urine and epoxy resin.The example of cold setting cement has polyurethane acetoacetic ester resin, water vinyl urethane resin.These adhesives can be with method brushing commonly used, as spraying, roller coating and dip-coating.
