Description

Bamboo-wood mixed particle board

Technical Field

The utility model relates to an wood-based plate production technology, concretely relates to 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 bamboo wood mixed particle board, this particle board utilizes bamboo wood plywood's leftover bits to smash and makes, has greatly saved bamboo wood material, can be used to make packing tray.

The utility model adopts the technical scheme as follows:

the utility model discloses a mixed granule board of bamboo wood, including inlayer and skin, the inlayer mixes the layer for the bamboo wood granule, 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 granule, second bamboo plaiting bamboo mat level is in the lower surface that the layer was mixed to the bamboo wood granule, first bamboo plaiting bamboo mat layer and second bamboo plaiting bamboo mat layer all mix the layer with the bamboo wood granule and closely laminate.

Due to the adoption of the structure, the bamboo and wood particle mixing layer is made by smashing the leftover materials of the bamboo and wood plywood, the bamboo and wood materials are saved by utilizing waste materials, the bamboo and wood plywood contains bamboo and wood glue, no other impurities exist, the bamboo and wood particles and the glue can be bonded together, the bonding property and the stability of the bamboo and wood particle mixing layer are ensured, and the strength of the bamboo and wood mixing plate is ensured. 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.

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.

Further, the water content of 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 is 10-100s/mm, depending on the thickness, generally 100 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:

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, the particle board has good use performance, and the particle board can be used for packaging trays.

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. 3-bamboo weaving bamboo mat, 2-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. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, the utility model discloses a mixed granule board of bamboo wood, including inlayer and skin, the inlayer mixes layer 2 for bamboo wood granule, and the leftover bits that the mixed layer of bamboo wood granule adopted bamboo wood plywood smashes to 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 the garrulous granule of bamboo wood 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 mixed board has been guaranteed. The outer layer is bamboo weaving bamboo mat 1, 3, and bamboo weaving bamboo mat and the mixed layer of bamboo wood granule are closely laminated, can fix the mixed layer of bamboo wood granule, guarantee the stability and the intensity of mixed granule board of bamboo wood.

In order to ensure uniform mixing and stable properties among bamboo and wood particles, the sizes of the bamboo and wood particles are further required to be basically consistent, the diameters of the particles are not more than 5mm, and meanwhile, in order to avoid the influence of moisture on the strength and stability of the particle board, the moisture content of the bamboo and wood mixed particles is required to be less than 10%.

In this embodiment, the manufacturing process of the bamboo-wood mixed particle board is as follows: screening bamboo and wood particles, mixing the bamboo and wood particles, gluing, assembling blanks according to a figure 1, hot pressing, cooling, trimming, inspecting and obtaining a finished product. Wherein, the optimized hot pressing parameters are as follows: the temperature is 120-130 ℃; the time is 10-100s/mm, depending on the thickness, generally 100 s/mm; the pressure is 13-14 MPa. Under the condition of the parameters, the particle board has the best service performance and can be used for manufacturing a packaging tray.

It is right above the utility model provides a bamboo wood mixing particle board has carried out the detailed introduction.

The principles and embodiments of the present invention have been explained herein using specific examples, which are presented only to aid in understanding the methods and their core concepts. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.
