Abstract

The utility model discloses a bamboo multilayer composite board, which is formed by bonding multiple layers of bamboo sheets with thicknesses smaller than 1 millimeter via adhesives through hot pressing. Compared with the prior art, the bamboo multilayer composite board has the advantages of fine elasticity, high strength, low manufacturing cost, and capability of being favorable for environmental protection.

Description

Bamboo multilayer composite sheet

Technical field

The utility model relates to sheet material manufacturing technology field, particularly a kind of multilayer composite sheet of being made by bamboo material.

Background technology

Bamboo multilayer composite sheet is to be made of the superimposed bonding of multilayer bamboo wood, existing bamboo multilayer composite sheet generally is no less than three layers of bamboo wood, every layer of bamboo wood all is to be arranged by bamboo bar weaving to constitute, the bamboo bar of adjacent two layers is staggered, the every layer thickness of this composite plate is bigger, every laminate is thick mostly more than 1.2 millimeters, the plate body density is low, intensity is the end of than, and is easy to crack, and globality is relatively poor, especially elasticity and torsional strength are lower, generally be used for construction material, range of application is big inadequately, does not give full play to the effect of bamboo material.

Summary of the invention

Problem to be solved in the utility model provides a kind of intensity height, the bamboo multilayer composite sheet of good springiness.

In order to address the above problem, the technical solution adopted in the utility model is: this bamboo multilayer composite sheet is made of the thermo-compression bonding of multilayer bamboo matter thin slice, and described bamboo matter thin slice has more than three layers; Every layer of described bamboo matter thin slice is spliced to form by the identical bamboo matter thin slice of the inner bamboo fiber orientation of polylith, and every layer of described bamboo matter sheet thickness is less than 1 millimeter.

In the technique scheme, the thickness of every layer of described bamboo matter thin slice is preferably between the 0.1-0.5 millimeter; In described each layer bamboo matter thin slice the bamboo fiber of the described bamboo matter of each piece thin slice towards arranging when identical, the bamboo fiber of the described bamboo matter thin slice of arbitrary layer towards with the minimum angle of cut of the bamboo fiber orientation of adjacent layer bamboo matter thin slice greater than 25 °; The arrangement of the bamboo fiber orientation of the described bamboo matter of each piece thin slice exists under the situation inequality in described each layer bamboo matter thin slice, have the described bamboo matter of one deck thin slice at least, the minimum angle of cut of its inner bamboo fiber orientation of wantonly two bamboo matter thin slices of splicing mutually is greater than 25 °.

The bamboo multilayer composite sheet of another kind of the present utility model is made of multilayer bamboo matter thin slice bonding, and described bamboo matter thin slice has more than three layers, and every layer of described bamboo matter thin slice is made of a monoblock bamboo matter thin slice, and every layer of described bamboo matter sheet thickness is less than 1 millimeter.

The thickness of every layer of described bamboo matter thin slice of this a kind of bamboo multilayer composite sheet is preferably between the 0.1-0.5 millimeter; Bamboo fiber orientation in the described bamboo matter of each layer thin slice is identical, the bamboo fiber of the described bamboo matter thin slice of arbitrary layer towards with the minimum angle of cut of the bamboo fiber orientation of adjacent layer bamboo matter thin slice greater than 25 °

Adopt the bamboo multilayer composite sheet of technique scheme compared with prior art to have following beneficial effect:

1, intensity height, its bending strength is than existing bamboo MULTILAYER COMPOSITE plate hight, and its shear strength is also than existing bamboo MULTILAYER COMPOSITE plate hight;

2, good springiness;

3, can be widely used in fields such as high-intensity sports equipment and family product.This multilayer composite sheet that is made of the identical bamboo matter thin slice of monoblock bamboo fiber orientation as every layer of bamboo matter thin slice can be used for sports equipments such as base plate of ping-pong bat, husky stand face plate, small-sized mini Loudspeaker panel; Every layer of bamboo matter thin slice can be used for family product etc. by the multilayer composite sheet that the polylith jigsaw constitutes.

The specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawing example:

Fig. 1, bamboo multilayer composite sheet shown in Figure 2 adopt the existing bonding agent of making glued board by 36 layers of bamboo matter thin slice, and bonding constitutes on hot press, and each layer bamboo matter sheet thickness d is 0.3 millimeter;

Bamboo each layer of multilayer composite sheet of basis shown in Fig. 3 example 1 bamboo matter thin slice is spliced to form by the square bamboo matter of polylith thin slice, and in one deck bamboo matter thin slice, the minimum angle of cut of the bamboo fiber orientation of two adjacent polylith bamboo matter thin slices is 90 °.

Bamboo multilayer composite sheet shown in Fig. 4 example 2, it each layer bamboo matter thin slice also is spliced to form by polylith bamboo matter thin slice, the bamboo fiber orientation of each piece bamboo matter thin slice is identical, this bamboo multilayer composite sheet, the minimum angle of cut degree towards with the bamboo fiber orientation of the bamboo matter thin slice of adjacent layer of the bamboo fiber of arbitrary layer of bamboo matter thin slice is 30 °.

Its each layer bamboo matter thin slice of bamboo multilayer composite sheet shown in Fig. 5 example 3 also is made up of a monoblock bamboo matter thin slice, the bamboo fiber orientation of each piece bamboo matter thin slice is identical, this bamboo multilayer composite sheet, the minimum angle of cut degree towards with the bamboo fiber orientation of the bamboo matter thin slice of adjacent layer of the bamboo fiber of arbitrary layer of bamboo matter thin slice is 30 °.

Other embodiment of the present utility model can contrast above-mentioned three examples, its every layer bamboo matter sheet thickness from 0.1 millimeter to 1 millimeter all can, its bed thickness is more little, the plate body intensity of acquisition is big more, elasticity is also good more; When the bamboo fiber orientation of each layer bamboo matter thin slice was consistent, the bamboo fiber orientation of adjacent two layers intersected its plate body better performances that obtains, and the minimum angle of cut generally just is not easy to ftracture when the plate bending greater than 25 °.
