Abstract
The utility model discloses a bamboo composite section, in particular a bamboo veneer, which comprises a bamboo green layer, a bamboo wood layer and a tabasheer layer. The bamboo green layer is provided with agglutinating grooves penetrating into the bamboo wood layer, and the agglutinating grooves have fixed section shapes formed by a material removing the layers from the bamboo green layer to the bamboo wood layer; and the surface area occupied by the agglutinating grooves accounts for 8 to 30 percent of the total area of the surface of the bamboo green layer. The surface of the bamboo green layer of the bamboo wood of the bamboo veneer is provided with the agglutinating grooves penetrating into the bamboo wood layer, and the agglutinating grooves have the fixed section shapes formed by the material removing the layers from the bamboo green layer to the bamboo wood layer, thus adhesives can be stayed in the agglutinating grooves to allow the agglutinating grooves to form an effective agglutinating area on the surface of the bamboo green. So, in the agglutinating process, the agglutinating grooves generate unobvious deformations under the pressure of high temperature and high pressure and colloids can not be extruded out to form an up-down three-dimensional agglutination layer by crossing the agglutinating grooves on the bamboo green surface, thereby greatly improving the agglutinating strength and improving the strength of the finished product veneer.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of bamboo composite section material bamboo single plate, comprise bamboo green layer, bamboo wood layer and tabasheer layer, described bamboo green layer is provided with the gummed groove that gos deep into the bamboo wood layer, and this gummed groove has by removing the constant cross-section shape that the material of bamboo green layer to the bamboo wood layer forms.
The shared surface area of described gummed groove is the 8%-30% of bamboo green layer total surface area.
The cross sectional shape of described gummed groove is opening rectangle, V font or arc.
The surface configuration of described gummed groove is ring-like, vertical bar type, sawtooth pattern or ripple type.
The utility model bamboo wood bamboo green layer surface is provided with the gummed groove of dark and bamboo wood layer, this gummed groove has by removing the constant cross-section shape that the material of bamboo green layer to the bamboo wood layer forms, this gummed groove is processed to form by machine cut, original material is all removed in the gummed groove, also can not return to the state of original undressed gummed groove, and the gummed groove has certain width, adhesive can rest in the gummed groove, makes the gummed groove form really effectively gummed area on the surf green surface.So when gummed, the gummed groove does not produce obvious distortion in the pressure of HTHP, colloid also can be extruded, and forms one by the interlaced three-dimensional up and down cementing layer that constitutes of gluing groove on the surf green surface, improved bonding strength greatly, production board intensity is improved.
Compared with prior art, the utlity model has following advantage:
1, the setting of gummed groove makes that effectively the gummed area increases, thereby makes bonding strength obviously improve, lead the glue eye with processing and compare, gummed back integral bending with height to 45～89MPa, even can be higher.
2, the setting of gummed groove makes that in the gummed process, the surf green surface can not deform because of extruding, therefore, and the surface smoothness height.
3, originally because surface, surf green surface is too smooth, can not provide enough big frictional force, make surperficial object tilt to overturn easily.Bamboo board behind the processing gummed lines determines that through contrast test its surperficial coefficient of friction will be much larger than the cork plate surface of identical function, and non-skid property is good, and surperficial object is difficult for tilting to overturn.It is even to glue together the lines distribution rule simultaneously, and surface aesthetic is generous, associative perception is strong.
