Abstract

The utility model discloses a corrugated bamboo-wood composite board, which comprises an upper layer, an intermediate layer and a lower layer and is corrugated, wherein the upper layer and the lower layer are bamboo chip layers; and the bamboo chip layers are cemented with the intermediate layer and green bamboo layers of bamboo chips face outwards. The intermediate layer is a single wood board or a multilayer board. Compared with the prior art, in the utility model, the bamboo chips are cemented with wood, so that boards on a plane form a corrugated structure; the green bamboo layers of the bamboo chips face outwards and are non-cemented layers; and cementing layers of the bamboo chips are tabasheer layers or fiber layers, so the bamboo chips are easily cemented with the intermediate layer and the cementing strength is high. Meanwhile, compared with other types of wood, the bamboo chips have high strength, so that the corrugated bamboo-wood composite board has higher strength and lower cost than other corrugated boards; and in addition, the bending resistance of the corrugated bamboo-wood composite board in the same direction is improved by 3-5 times compared with the bamboo-wood composite board with the same size. Meanwhile, the utility model has the advantages of reducing the carbon emission amount and the weight, simplifying the production process, improving the production efficiency and reducing the production cost.

Description

A kind of ripple bamboo-wood composite board

Affiliated technical field:

The utility model relates to a kind of bamboo-wood composite board, belongs to wood-based plate and makes the field.

Background technology:

Along with the sustainable development of China fast-growing, high-yield woods, as: quick growth poplar wood, the living pine of speed progressively become a kind of suitable rich in natural resources and are adopted in a large number by the wood-based plate manufacturing industry.Though fast growing, its physical and mechanical property is lower.Bamboo is the distinctive resource of China and Southeast Asia one band, and not only big, the physical and mechanical property of the amount of storing up is higher than fast growing wood far away, and has advantages such as fast growth, sustainable development, carbon emission amount are low.Research for many years, application and development bamboo wood through domestic scientific and technical personnel and relevant enterprise have been widely applied in the wood-based plate manufacturing industry.

The fast growing wood of having developed at present and the composite product of artificial bamboo board mainly contain:

CN 87100368.6 bamboo plywoods are made way

CN 91108203.4 improved bamboo plywood manufacturing process ways

CN 92107278.3 bamboo weaving lagers stacked materials and manufacturing way thereof

CN 98227629.X improved laminated bamboo-wood composite lumber

CN 02258059.X poplar base composite plate

03112794.0 1 kinds of bamboo woods of CN strengthen laminated veneer lumber and manufacturing way thereof

03152841.4 1 kinds of container bottom boards of CN and manufacturing way thereof

Or the like.

Bamboo is made up of the tabasheer layer and the middle fibrage of outer field bamboo green layer, internal layer, bamboo green layer contains a large amount of waxs, thereby can't bond, so with other section bars bondings the time, all bamboo green layer to be cutd open with other section bars, fiberfill layer bonds, this method caking property is good, and relative intensity is higher, more than but waste of material is serious, operation is many simultaneously, and the processing cost height is not easy to industrialization.A kind of bonding process that utilizes isocyanate glue to carry out bamboo green layer and Wooden veneer is provided in Chinese patent 200510038523, said as invention itself, isocyanate glue is the price height not only, and it is bigger to contain toxicity, requirement of shelter is also high during operation, and to the greatest extent let it be, and consumption is few, but is conspicuous to the harm that the operator brings, simultaneously, this composite board can not be complied with the demand for development of asepsis environment-protecting.

And be subjected to the influence of traditional plane bonding process, and the bending strength of slim bamboo-wood composite board is undesirable, and volume is big, and quality is heavy, and is crooked easily.

Therefore how to make full use of China quite abundant bamboo wood, fast growing wood resource, the wood-based plate composite product of producing high strength, low price becomes new problem.

The utility model content

In order to overcome above shortcomings in the prior art, the utility model aims to provide a kind of bending strength height and the low ripple bamboo-wood plyboard of cost.This bamboo-wood plyboard adopts the three-dimensional bonding process of waveform in order to have improved the bending strength of composite product, makes the sheet material on plane form ripple struction.

To achieve these goals, the utility model has adopted following technical scheme:

A kind of ripple bamboo-wood composite board comprises three layers of upper, middle and lowers and becomes corrugated, described two-layer up and down be the bamboo chip layer, the bamboo green layer of described bamboo chip layer and gluing of described intermediate layer and bamboo chip is outside.

Described intermediate layer is veneer or multi-layer sheet.

The utility model ripple bamboo-wood plyboard is exerted pressure and heat under the press device that the ripple pattern is arranged, and the non-bamboo green layer and the intermediate layer speed of the two-layer bamboo chip of skin are given birth to the veneer bonding.Make it become the waveform bamboo-wood plyboard.

Beneficial effect: the utility model compared with prior art, the utility model adopts bamboo chip and timber gluing, make the sheet material on plane form ripple struction, the bamboo green layer of bamboo chip outside, be non-adhesive layer, the adhesive layer of bamboo chip is tabasheer layer or fibrage, so bamboo chip and intermediate layer are easy to gluing, and the cementing strength height.Simultaneously, bamboo chip is compared with other timber, and its intensity height is so than other ripple sheet material intensity height, cost is low; And than having improved 3-5 with the equidirectional anti-bending strength of the bamboo-wood composite board of volume doubly.Reduce carbon emission simultaneously, alleviated weight, simplified production technology, improved production efficiency, reduced production cost.

Wherein: 1. bamboo chip layer, 2. intermediate layer, 3. bamboo chip layer, 4. adhesive layer, 5. adhesive layer

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is elaborated:

As shown in Figure 1, the corrugated bamboo-wood plyboard of the utility model is made of for three layers upper, middle and lower, wherein two-layer up and down is bamboo chip, and middle one deck is a veneer, and adopts adhesive bonding, form adhesive layer between bamboo chip and veneer, the back forms the ripple pattern in moire pattern.Wherein, multi-layer sheet also can be adopted in the intermediate layer.

The utility model composite plate manufacturing process is as follows:

With bamboo chip by specific length, veneer cuts to given size;

2. adhesive coating on non-bamboo green layer of bamboo chip and veneer;

3. with the non-bamboo green layer and the veneer assembly of two-layer bamboo chip;

4. assembly is positioned over and forms the ripple pattern in the moire pattern;

5. revise and cut to the needs specification.

Claims

1. a ripple bamboo-wood composite board comprises three layers of upper, middle and lowers and becomes corrugated, it is characterized in that: the described two-layer up and down bamboo chip layer that is, the bamboo green layer of described bamboo chip layer and gluing of described intermediate layer and bamboo chip is outside.
