Abstract

The present invention proposes a kind of processing technology of high-density bamboo material.The bamboo bar after insect protected, mildew-resistant are handled, is sent into double-roll rolling mill, improve bamboo wood density by rolling.Bamboo wood through this processes has the not funginert performance of warpage of making moist, and can be widely used in the flooring, wall decoration.

Description

Process for manufacture of high-density bamboo material

The invention belongs to bamboo processing technology.

Modern Interior Decoration more and more biases toward the material of giving the impression that goes back to nature, particularly assembled floor-board, from ceramic tile, granite, marble to senior teak, the bamboo floor, people more like the latter's grace, honesty, nature.But teak selection difficulty, resource shortage, bamboo timber resource is abundant, but humidity resistance is poor, easy deformation.For solving the humidity resistance of bamboo wood, the CN1058822 patent has proposed a kind of with cement, pitch is the plate substrate material, bamboo wood is the composite plate on surface, because the expand with wet and contract with dry coefficient of bamboo wood is different with cement plate, change along with doing of weather is wet, the bamboo plane materiel splits away off from cement plate gradually, can not fundamentally solve bamboo wood make moist back warpage, problem such as mouldy.

In order to overcome the shortcoming of above-mentioned prior art, the present invention proposes a kind of raising bamboo wood density, to increase the bamboo processing technology of humidity resistance.The bamboo wood of crossing by this processes has improved resistance to deformation, humidity resistance.

The present invention realizes like this.Go green grass or young crops to go Huang to dry by the fire to moisture content 40%～70% after handling by boiling, insect protected, mildew-resistant bamboo wood again, send rolling mill then to and carry out rolling, rolling density can be as required at 0.75～0.95g/cm ³Between adjust, at last bamboo wood is dried.Base reason of the present invention is the tubular fiber that the rolling of bamboo wood process has destroyed bamboo wood inside, has reduced the bamboo wood inner space, thereby makes outside moisture be difficult for being absorbed by tubular fiber again, thus the protection against the tide that has improved bamboo wood, anti-deformation.Moisture content is too high before the bamboo wood rolling, needs to increase rolling number of times, cross low then rolling easily and split, with 40～70% for well.

Fig. 1 is the schematic diagram of technique for rolling of the present invention.

Below in conjunction with drawings and Examples the present invention is described further.

Embodiment: go green grass or young crops to remove Huang in bamboo, with machining well-thought-out plan bar (2), after boiling, insect protected, mildew-resistant are handled, dry by the fire to moisture content approximately 60%, sending two rolling mills (1) then to, to be rolled to density be 0.92g/cm ³, carry out the finish-milling shaping after the oven dry for the second time again, become the high-density bamboo bar.The high-density bamboo sheet material of high-density bamboo bar one-tenth different shape capable of being combined is with the compound various high-density bamboo composite boards that become capable of being combined of all kinds of glued boards.

Physical function parameter such as following table before and after the bamboo wood rolling

After the preceding rolling of rolling

The coefficient of shrinkage 0.33 0.05

Bulking coefficient 7.25 0.2

Basic density 0.46g/cm ³0.92g/cm ³

Hardness 350kgf/cm ²583kgf/cm ²

The present invention compared with prior art has the following advantages:

1. through the bamboo wood of this PROCESS FOR TREATMENT, have good protection against the tide, indeformable, the performance of not going mouldy;

2. combine construction timbers such as making the floor with other base material and do not come unstuck, do not stick up in the wrong.

3. processing method is simple, is suitable for a large amount of suitability for industrialized production.

Claims

1, a kind of process for manufacture of high-density bamboo material goes green grass or young crops to go to yellow back by boiling in bamboo, and insect protected, mildew-resistant are handled, and it is characterized in that using two rolling mills [1] to carry out rolling, to improve bamboo wood density again.

2, bamboo processing technology according to claim 1 is characterized in that before the rolling bamboo wood being dried to moisture content 40～70%, all oven dry again after the rolling.

3, bamboo processing technology according to claim 1 is characterized in that rolling density is as required at 0.75～0.95g/cm ³Between adjust.
