Abstract

The utility model discloses a composite board with a veneer core layer made of flakes on the surface; the composite board comprises a surface layer (1), a bottom layer (2) and a core layer (3), wherein the surface layer (1) and the bottom layer (2) are made of solid wood veneers; the core layer (3) is made of a plurality of flakes; the flakes of the core layer (3) are paved vertically and horizontally in a staggering way according to a grain direction; and a hot-pressing gluing method is adopted for connection among the surface layer (1), the core layer (3) and the bottom layer (2) and among the flakes of the core layers (3). The composite board has the advantages of better tensile and deformation resistance performances, good elasticity, strong stability, high quality and cost performance and can be manufactured into high-grade furniture boards, high-grade panels for decoration and middle-high grade building templates.

Description

A kind of surface is the composite plate of flaking for the veneer sandwich layer

Technical field

The utility model relates to ornament materials, and being specifically related to a kind of surface is the composite plate of flaking for the veneer sandwich layer.

Background technology

The classification of existing plate kind mainly contains following several:

1, solid wood plate, the wood plank that adopts complete log to make exactly.2, glued board is formed by three layers or multilayer veneer or the hot pressing of thin plate sticker.3, decoration panel is that the accurate slicing of solid wood plate is become thickness is micro veneer skin about 0.2mm, is base material with clamping plate, manufactures the dalle with single face decoration function that forms through adhesion process.4, core-board is to be formed by the sticking Wood block floor of pressing in the middle of two veneers.5, particieboard is to be primary raw material with wood particulate, adds glue again, the repressed slim sheet material that forms of additive.6, density board also claims fiberboard.Be to be raw material, apply the artificial board that Lauxite or other adhesive that is suitable for are made with wood fibre or other plant fiber.7, PLASTIC LAMINATED is that employing siliceous material or calcareous material are primary raw material, mixes with a certain proportion of fibrous material, aglite, binder and chemical addition agent, through steaming the dalle that the pressure technology is made.8, melamine decorative veneer, full name are melamine-impregnated bond paper facing wood-based plates.Be that the paper that will have different colours or a texture is put into the melamine resin adehsive stick and soaked, be dried to certain state of cure then, it is mated formation on particieboard, medium density fibre board (MDF) or hardboard surface, the decorative panel that forms through hot pressing.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of brand-new plate kind is provided, and the surface is the composite plate of flaking for the veneer sandwich layer.

Technical solution of the present utility model is: it comprises that top layer and the bottom made by plates of solid wood reach the sandwich layer of being made by the several layers flaking, interlace in length and breadth by grain direction between its each layer flaking of sandwich layer and mat formation, be connected by hot-press gluing between top layer, sandwich layer and the bottom and between each layer flaking of sandwich layer.

Technique effect of the present utility model is: it has the characteristic of tension, anti-deformation preferably, and good springiness, stability are strong, quality, cost performance height, can be made into high-grade furniture-plates, the high-grade fitting-up building template with sheet material, low-medium-high level.

Description of drawings

Fig. 1 is a three-dimensional structure diagram of the present utility model.

The specific embodiment

As shown in Figure 1, it comprises that top layer 1 and the bottom 2 made by plates of solid wood reach the sandwich layer of being made by the several layers flaking 3, interlace in length and breadth by grain direction between sandwich layer 3 its each layer flakings and mat formation, be connected by hot-press gluing between top layer 1, sandwich layer 3 and the bottom 2 and between each layer flaking of sandwich layer 3.

When hot pressing, overlap 1-1.5cm between each adjacent plates of solid wood of described top layer 1 and bottom 2.

Procedure of processing:

A, rotary cut venner: with not having card or having center veneer lathe timber to be peeled into the veneer of required specification.B, long material flaking: timber is dug into the flaking of required specification with special-purpose long material chipper.C, veneer gluing: the veneer uniform gluing, be generally 20g/ ㎡-30 g/ ㎡ with glue spreader.D, flaking applying glue: with special-purpose flaking glue mixer is the flaking applying glue, is generally 100kg/m3-120kg/m3. e, the shop fixtures plate: the base plate of gluing is layered on the conveyer belt in order, overlaps 1-1.5cm between two adjacent panels. f, flaking mats formation: with special-purpose orienting spreading machine the flaking of applying glue evenly is layered on the base plate, the branch three-decker of mating formation, for vertically mating formation, the intermediate layer is for laterally mating formation up and down. g, the overlay veneer: on the flaking that the panel of gluing is paved in order, overlap 1-1.5cm between two adjacent panels. h, hot pressing: hot pressing temperature is generally 180-200 ℃, pressure 20 MPas.

This product is a kind of brand-new sheet material, the surface is a plates of solid wood, middle long stapled flaking is mated formation by rule, then through hot-forming and remarkable sheet material every physical and mechanical property excellence of obtaining, this sheet material has the characteristic of tension, anti-deformation preferably, and good springiness, stability are by force.This sheet material is with its excellent physicochemical property, cheap raw material sources, and the production technology of environmental protection has exceeded other sheet materials fully.This product can be with low-quality raw materials such as undersized log, brush wood, non-dimension timbers as core, and various low-medium-high level timber are that raw material is processed into veneer.Can be used as high strength, structure sheet material that rigidity is big, also can be used for top-grade furniture material, the fitting-up sheet material with material or common various uses such as building template, application is very extensive.

Claims

1. a surface is the composite plate of flaking for the veneer sandwich layer, it is characterized in that, it comprises that top layer (1) and the bottom (2) made by plates of solid wood reach the sandwich layer of being made by the several layers flaking (3), interlace in length and breadth by grain direction between its each layer flaking of sandwich layer (3) and mat formation, be connected by hot-press gluing between top layer (1), sandwich layer (3) and the bottom (2) and between each layer flaking of sandwich layer (3).
