Description

Novel bamboo-wood mixed particle board

Technical Field

The utility model relates to an wood-based plate production technology, concretely relates to novel bamboo wood mixing particle board.

Background

China has abundant bamboo resources, but wood resources are lack, so that the artificial bamboo-wood mixed plate is developed in order to relieve the shortage of the wood resources and further protect the environment. However, the existing bamboo-wood mixed plate is mostly made by multilayer mixing and alternate processing of bamboo and wood materials, which causes certain waste to bamboo and wood to a certain extent, and at present, because the impurities of bamboo waste are more, the bamboo-wood mixed plate made of the bamboo waste is rare.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: to the problem that above-mentioned exists, provide a novel bamboo wood mixed particle board, this particle board utilizes bamboo wood plywood's leftover bits to smash and makes, has greatly practiced thrift bamboo wood material, not only can be used to make packing tray, can also extensively be used for building trade, decoration trade.

The utility model adopts the technical scheme as follows:

the utility model discloses a novel mixed granule board of bamboo wood, including inlayer and skin, the inlayer is the mixed layer of bamboo wood grain, the skin is bamboo plaiting bamboo mat layer for the bamboo, bamboo plaiting bamboo mat layer includes that first bamboo plaiting bamboo mat layer and second bamboo plaiting bamboo mat layer, first bamboo plaiting bamboo mat level is in the upper surface that the layer was mixed to the bamboo wood grain, second bamboo plaiting bamboo mat level is in the lower surface that the layer was mixed to the bamboo wood grain, first bamboo plaiting bamboo mat layer and second bamboo plaiting bamboo mat layer all mix the layer with the bamboo wood grain and closely laminate, the outer outside still is provided with the wood veneer layer, the wood veneer layer includes first wood veneer layer and second wood veneer layer, first wood veneer layer closely laminates at first bamboo plaiting bamboo layer upper surface, the second wood veneer layer closely laminates at second bamboo plaiting bamboo mat layer lower surface.

Owing to adopt above-mentioned structure, bamboo wood granule mixes layer adoption bamboo wood plywood's leftover bits and pieces smashes and make, waste utilization, bamboo wood material has been saved, and contain bamboo wood and glue in the bamboo wood plywood, do not have other impurity, can bond between the garrulous granule of bamboo wood and the glue and combine together, the associativity and the stability that the layer was mixed to bamboo wood granule has been guaranteed, thereby the intensity of bamboo wood mixed plate has been guaranteed, the bamboo wood granule mixes the layer and sets up two layers bamboo woven bamboo mat layer outward, further promote the stability of granule board, make it have good performance, and simultaneously, further set up the veneer layer at the skin, the veneer layer is compared in the moisture absorption ability reduction of bamboo woven bamboo mat layer, non-deformable, can protect the inlayer, make bamboo wood granule mixed plate more durable, enlarge its application range.

Further, wood veneer layer outside is provided with the flooding paper layer, the flooding paper layer includes first flooding paper layer and second flooding paper layer, first flooding paper layer closely laminates at first wood veneer layer upper surface, second flooding paper layer closely laminates at second wood veneer layer lower surface, preferably, the flooding paper is melamine flooding paper.

Due to the adoption of the structure, the melamine impregnated paper is further arranged outside the wood veneer layer, so that the wood veneer layer can be protected, the wood veneer layer is prevented from being damaged, the strength and the stability of the particle board can be improved, the particle board can be applied to a packaging tray, the building industry and the decoration industry, and the application range is expanded.

Further, the mixed layer of bamboo wood granule is formed by bamboo, the mixed crushed aggregates of wood, in order to make the misce bene between the bamboo wood granule, and quality and size are even stable, bamboo wood granule size is unanimous basically. Preferably, the diameter of the bamboo wood particles is not more than 5 mm.

Preferably, the wood veneers are spliced by a splicer, the water content of the wood veneers is less than 10%, and the toughness and the strength of the wood veneers spliced by the splicer can be improved.

Further, the water content of the bamboo woven bamboo mat and the bamboo and wood mixed particles is less than 10%. Too big cohesion that influences between the thin bamboo strips used for weaving, influence the sizing and hot pressing effect easily, and cause the particle board to corrode easily, can avoid these problems with the moisture content control within 10%.

Further, the manufacturing process comprises the following steps: screening bamboo and wood particles, mixing the bamboo and wood particles, gluing, assembling, hot pressing, cooling, trimming, inspecting and obtaining the finished product. Preferably, the hot pressing parameters are as follows: the temperature is 120-130 ℃; the time depends on the thickness and is generally 10 s/mm; the pressure is 13-14 MPa.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

1. the bamboo wood granule mixes the layer and adopts bamboo wood plywood's leftover bits to smash and make, and waste utilization has saved bamboo wood material, and contains bamboo wood and glue in the bamboo wood plywood, does not have other impurity, can bond between bamboo wood granule and the glue and combine together, has guaranteed the associativity and the stability that the layer was mixed to bamboo wood granule to the intensity of bamboo wood granule hybrid sheet has been guaranteed. Meanwhile, two bamboo woven bamboo mat layers are arranged outside the bamboo and wood particle mixed layer, so that the stability of the particle board is further improved, and the particle board has good use performance.

2. Further set up the wood veneer layer at the skin, set up melamine impregnated paper can effectively promote the intensity and the stability of particle board in wood veneer layer outside, make it not only can be applied to packing tray, can also be applied to building trade and decoration trade, enlarged the range of application.

Drawings

Fig. 1 is the structure schematic diagram of the bamboo-wood mixed particle board of the utility model.

The labels in the figure are: 1. 7-melamine impregnated paper, 2, 6-wood veneers, 3, 5-bamboo woven bamboo mats and 4-bamboo and wood mixed particles.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
