Abstract
A cavity type bamboo board comprises an upper bamboo panel layer and a lower bamboo panel layer. A cavity is formed between the upper bamboo panel layer and the lower bamboo panel layer. Part of the cavity or the whole cavity is filled with core materials which are bamboo culms or bamboo dices or bamboo sections or bamboo rings or bamboo tubes or bamboo strips or bamboo pieces or bamboo skin or bamboo filaments or bamboo wool or bamboo hair or bamboo flocks. The cavity type bamboo board has the advantages that the size is small, the number of production processes is reduced, the utilization rate of bamboo wood is increased by more than 15%-50%, the functions of sound absorption, noise reduction and heat insulation are achieved, and the buoyancy is increased by more than 20%-60%.

The surrounding of core at least establishes two frames, and frame and core and upper and lower two-layer bamboo panel are composited by viscose glue, and frame flushes with the limit of upper and lower two-layer bamboo panel.
Stull is provided with between the longitudinal edge of frame.
Described chamber is rule or irregular, and chamber is through or not through or be communicated with or be not communicated with, and chamber wall is connected or is not connected.
Described core is the core layer be clipped in the middle of upper and lower laminate, core layer single or multiple lift, independent stratification or to harden synthesis layer with bottom or surface layer.
The processing method of cavate bamboo board, concrete procedure of processing is as follows:
1. prepare former bamboo or head and tail of bamboo or make the discarded bamboo that firewood burns;
2. surface layer plate and bottom plate and bamboo circle core, bamboo block core or bamboo wool top core is prepared;
3. bamboo circle is sawed: it is circular bamboo circle that bamboo is sawn into cross section by the contour length standard of frame; Or bamboo is cutd open bamboo block or the bamboo wool top core of thickness by the contour length standard of frame;
4. clean bamboo circle, by clean for the sawdust wind at Zhu Quan two ends;
5. gluing, to the internal sizing of bottom plate;
6. cobordant frame, is placed on the glue layer of bottom plate by frame;
7. fill out Zhu Quan, bamboo block or bamboo wool top, by bamboo circle or bamboo block or bamboo wool top rule irregular or staggered or be staggered and be filled in frame;
8. gluing, opposite laminate internal sizing;
9. cover plate, by surface layer plate applying glue cover on the frame filling up bamboo circle or bamboo block or bamboo wool top;
10. plate tied up by assembly, and the binding of bottom plate, bamboo circle core and surface layer plate three ply board adhesive tape is firmly become slab;
gummed, sends hot press solidification gummed to by slab;
ejecting plate, draws off the slab solidified, tears adhesive tape off from hot press, namely completes the processing of cavate bamboo board.
The moisture content of described surface layer plate, bottom plate, frame, Zhu Quan, bamboo block or bamboo wool top or bamboo chip is 9-14%.
The described gummed temperature that is heating and curing is 86-103 DEG C, and the time is 3-12 minutes, and the principal pressure of hot press pressure is 5 ~ 12MPa, and side pressure pressure is 0.2 ~ 2.5Mpa.
Beneficial effect of the present invention: 1, volume is light, comparing product with volume with equal purposes can more than weight reduction 20%-60%, and along with the increase of thickness, proportion is less; 2, reduce production process, depending on product structure and purposes, force plane or adjustable cast iron planes can be exempted from; 3, utilization rate of bamboo improves more than 15-50%.4, there is sound-absorbing, noise reduction, heat insulating function; 5, more than buoyancy 20%-60% is increased; 6, suddenly cold and hot tolerance is strong, not easily splits; 7, rapid dry rapid wet tolerance is strong, not easily splits; 8, the bamboo that the bamboo etc. that bamboo head and bamboo tail, dwarf bamboo, large branch and defect can not be used for normal use is discarded can use, and does not waste; 9, practical, applied range, its manufactured goods or semi-finished product or parts are extensively applicable to decoration, shipbuilding, furniture, gardens gardening, case cabinet, sports goods, field industry and the daily life tools articles for use such as storage, packaging, food, movie theatre, arenas, auditorium, handicraft manufacturing industry is applied.

Detailed description of the invention
Embodiment 1: as Figure 1-Figure 4, cavate bamboo board, comprise upper and lower two-layer bamboo panel (1,2), described upper and lower two-layer bamboo panel (1,2) form chamber between, chamber is locally interior or be all filled with core 4, and core 4 is bamboo circle (becoming the ring-type of certain altitude from the tail ending position sawing of bamboo).The height of bamboo circle is equal with frame height in the present embodiment.
The surrounding of core 4 establishes four frames 3, and frame and core and upper and lower two-layer bamboo panel are composited by viscose glue, and frame flushes with the limit of upper and lower two-layer bamboo panel.
Be provided with stull 5 between the longitudinal edge of frame, prevent frame from caving in.
