Abstract

The invention discloses a bamboo composite plate with a honeycomb-shaped middle layer, which is formed by compounding an upper layer, a middle layer and a lower layer, wherein the middle layer is formed by mutually crossing, mutually tenon-and-mortise meshing and mutually meshing a plurality of side-standing upper bamboo strips with a plurality of meshing lower openings and a plurality of side-standing lower bamboo strips with a plurality of meshing upper openings, and each contact surface is provided with an adhesive. The invention also discloses a preparation method of the plate, which comprises the following steps: mixing bamboo filaments, bamboo strips and bamboo chips, and dipping the mixture in glue to press an upper layer and a middle layer with required thickness; cutting the bamboo chips into upper bamboo strips and lower bamboo strips with required height and width; processing a lower opening and an upper opening of the upper bamboo batten and the lower bamboo batten according to the requirement of the distance; gluing and meshing the upper bamboo batten and the lower bamboo batten with each other to form an intermediate layer; and gluing and pressing the contact surfaces of the upper surface layer and the middle layer and the contact surfaces of the middle layer and the lower surface layer. Has the advantages that: raw materials are saved, the weight is light, the glue consumption is less, and the deformation is not easy.

Description

The bamboo matter composite plates in cellular intermediate layer and preparation method thereof

Technical field

The present invention relates to a kind of bamboo matter composite plates, specifically, is that a kind of intermediate layer becomes cellular bamboo matter composite plates, the invention still further relates to the preparation method of this plate.

Background technology

Along with the raising of expanding economy and people's living standard, plate (floor, metope pasting board, partition plate) has got into office, meeting room and common people family more and more as ornament materials.Since the technology of wood substituted by bamboo was implemented, a large amount of bamboo woods was made into various plates, and people work to satisfy, the demand in inhabitation place, and the cutting capacity, the protection ecological balance that reduce the forest timber resource have been made the contribution of performing meritorious deeds never to be obliterated.

The bamboo scutum piece of prior art is that the impregnation compacting is integrated into has certain thickness entity structure mostly with a kind of or two kinds of mixing or three kinds of mixing in bamboo silk, bamboo bar, the bamboo chip.Its weak point is: 1. waste of raw materials, the plate of entity structure rely on raw material to fill compacting fully, so uneconomical in the raw-material utilization; 2. Heavy Weight, through the proportion of the integrated plate of compacting about 1.1, so Heavy Weight; 3. the glue consumption is big, and raw material are integrated into plate and rely on glue and pressure, so the glue consumption is big; 4. easy deformation, raw material can produce the internal stress of various forms in pressing process, so, deform easily through the integrated plate of compacting.

Summary of the invention

The objective of the invention is to overcome the deficiency of prior art, a kind of conservation of raw material, in light weight, few, the on-deformable bamboo matter of glue consumption combined plate are provided, the present invention also aims to provide a kind of method for preparing this bamboo matter combined plate.

The technical scheme of the bamboo matter composite plates in the cellular intermediate layer of the present invention; Be composited by upper layer, intermediate layer, following surface layer; Said upper layer is the Integral bamboo veneer piece with following surface layer; Said intermediate layer by many edge-on last bamboo bars and many edge-on following bamboo bars with a plurality of engagement upper sheds with a plurality of engagement under sheds intersect each other, each other the tenon fourth of the twelve Earthly Branches, be engaged with each other and form, said upper layer and intermediate layer, intermediate layer and following surface layer, the contact surface of going up bamboo bar and following bamboo bar have adhesive.

The preparation method of the bamboo matter composite plates in the cellular intermediate layer of the present invention is following:

With wherein a kind of or wherein two kinds of mixing or the three kinds of mixing in bamboo silk, bamboo bar, three kinds of raw material of bamboo chip, impregnation is pressed into the upper layer and the intermediate layer of desired thickness;

Bamboo chip is cut into the last bamboo bar and following bamboo bar of desired height and width;

Perhaps a kind of in bamboo silk, bamboo bar, the bamboo chip or two kinds are mixed or three kinds of mixing, impregnation is pressed into the blanket of bamboo bar and following bamboo bar in the making of desired height, cuts into the last bamboo bar and the following bamboo bar of desired height and width;

With last bamboo bar and of requirement processing under shed and the upper shed of following bamboo bar according to spacing;

To go up the bamboo bar and mesh into the intermediate layer with the mutual gluing of following bamboo bar;

Contact surface gluing press forming with upper layer and intermediate layer, intermediate layer and following surface layer.

The beneficial effect of bamboo matter combined plate of the present invention is: conservation of raw material, in light weight, the glue consumption is few, not yielding.

Fig. 1 is the structural representation of bamboo matter combined plate of the present invention;

Fig. 2 is the I place enlarged drawing among Fig. 1;

Fig. 3 is last bamboo bar and the structural representation of under shed among Fig. 2;

Fig. 4 is the structural representation of following bamboo bar, upper shed and following surface layer among Fig. 2.

The specific embodiment

The bamboo matter composite plates in Fig. 1, Fig. 2, Fig. 3, cellular intermediate layer shown in Figure 4; Be composited by upper layer 1, intermediate layer 2, following surface layer 3; Said upper layer 1 is Integral bamboo veneer pieces with following surface layer 3; Said intermediate layer 2 by many edge-on last bamboo bars 4 and many edge-on following bamboo bars 6 with a plurality of engagement upper sheds 7 with a plurality of engagement under sheds 5 intersects each other, each other the tenon fourth of the twelve Earthly Branches, be engaged with each other and form, said upper layer 1 and intermediate layer 2, intermediate layer 2 and following surface layer 3, upward the contact surface of bamboo bar 4 and following bamboo bar 6 has adhesive.

The preparation method of the bamboo matter composite plates in this cellular intermediate layer is following:

Bamboo silk, bamboo bar, bamboo chip are mixed, and impregnation is pressed into the upper layer 1 and intermediate layer 2 of desired thickness;

Bamboo chip is cut into the last bamboo bar 4 and following bamboo bar 6 of desired height and width;

With last bamboo bar 4 and the requirement processing under shed 5 and upper shed 7 of following bamboo bar 6 according to spacing;

To go up bamboo bar 4 and mesh into intermediate layer 2 with following bamboo bar 6 mutual gluings;

With the contact surface gluing press forming of upper layer 1 with intermediate layer 2, intermediate layer 2 and following surface layer 3.
