Abstract

The utility model relates to a lightweight sheet with plant straws, composed of a dash board, a core board, core materials and a frame. The outermost layer is the dash board, and the core plate is arranged at the inner side of the dash board, and the intermediate layer is plant straw core materials, wherein, the core materials are longitudinally arranged in the frame, and each layer is bonded by adhesives. The utility model has the advantages of light weight, acoustic insulation, thermal insulation, size holding, lumber saving, etc.

Description

Lightweight sheet

The utility model relates to a kind of light body plate that has the plant straw, belongs to a kind of artificial board, is specially adapted to do door-plate, table, seat and does insulation and decoration sheet material.

The artificial board that uses has sawdust glued board, vegetable fibre board, particieboard at present, it is not stratified glued board, common characteristic is to save timber, but exist that intensity is low, the life-span lacks, be not incubated, poor surface smoothness, integral body be not attractive in appearance, flexible type, three-ply board, five-ply board are to form with the thin plate stratification gummed, are to make with pure timber, waste timber.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and a kind of intensity height, indeformable, insulation, sound insulation, any surface finish, attractive in appearance, the light body plate of saving timber are provided.

The purpose of this utility model is achieved in that it is made of dash board, central layer, core material, frame, and outermost layer is a dash board, is central layer in the dash board, and the intermediate layer is a plant straw core material, and core material places in the frame, and each interlayer is bonding with adhesive.

The purpose of this utility model can also realize by following technical measures: core material, with the bluish dogbane bar is the best, and the length of its straw equals to remove the thickness of institute's making sheet behind dash board, the central layer, and it vertically is arranged in the frame, frame adopts modification timber, and adhesive adopts electronics high frequency resin glue.

The utility model has following advantage compared to existing technology:

1,,, and saves timber so this plate body is light, sound insulation, insulation because this plate intermediate layer is plant straws such as bluish dogbane bar;

2, the utility model frame adopts modification timber, therefore can not be out of shape and lose shape;

3, intensity height, any surface finish are attractive in appearance.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model cutaway view.

Among the figure: dash board (1), central layer (2), frame (3), core material (4).

Embodiment describes the utility model in detail below in conjunction with (accompanying drawing): the utility model outermost layer is dash board (1) as shown in the figure, it is wooden good to require, neatly, be the uniform central layer of thickness (2) in the dash board (1), the intermediate layer is core material (a 4) plant straw, the utility model is the bluish dogbane bar, it can also use corn stalk, corncob, high grain bar, but need do insect protected, preservative treatment, vertically is arranged in the frame (3), the timber that frame (3) is handled for modification, moisture content is no more than 0.8%.

The production technology of light body plate is: sawing, oven dry, processing, the making of frame (3) material; The choosing of the matter of bluish dogbane bar, dry, disconnectedly cut, screen, disconnectedly cut the thickness that length equals to remove dash board (1), the making sheet of central layer (2) back institute, promptly equal the height of frame (3), the rotary-cut of veneer, oven dry, shearing, piece; After above-mentioned material is got all the ready, spread veneer, put frame, carry out that bluish dogbane bar core material (4) is mated formation, gluing, hot pressing, smartly cut out, the sand milling polishing makes product.

Claims

1, a kind of light body plate is layer structure, it is characterized in that it is made of dash board, central layer, core material, frame, and outermost layer is a dash board, is central layer in the dash board, and the intermediate layer is a plant straw core material, and core material places in the frame, and each interlayer is bonding with adhesive.

2, light body plate according to claim 1 is characterized in that core material is good with the bluish dogbane bar, and straw length equals to remove the thickness of institute's making sheet behind dash board, the central layer, and it vertically is arranged in the frame.
