Plastics coated ply-bamboo is to be that main material is made sandwich layer with the bamboo curtain splint, is internal layer with bamboo mat or veneer, and the top layer is the bond paper of impregnated phenolic resin, adopts a plastic plating technology to make.

The bamboo mat glued board is to be to constitute the unit with the bamboo mat, a kind of artificial bamboo board that drying, applying glue, hot pressing form, and production technology is simple, the small investment of founding the factory, utilization rate of bamboo is higher and use more extensive.

Tangential thin bamboo strips used for weaving curtain glued board is that bamboo wood is tangentially cutd open the thin bamboo strip, knits curtain and tangential gummed and a kind of product of obtaining.Owing to,, it must be rejected in order to obtain good gummed at surf green, the tabasheer that the tangential existence of bamboo wood is difficult to glue together, therefore both reduced the tangential production efficiency of cuing open the thin bamboo strip, more greatly reduce the utilization rate of bamboo wood.

The formation unit of reorganization bamboo is a netted bamboo bundle, earlier bamboo wood is discongested into elongated and is cross-linked with each other and keeps the loose reticular fibre bundle of the original arrangement mode of fiber, the tabular or other forms of material that hot pressing forms after drying, applying glue, the assembly moulding again.The characteristics of reorganization bamboo are fully rationally to utilize the inherent characteristic of bamboo fiber material, have both guaranteed the high usage of bamboo wood, have kept the original physical and mechanical property of bamboo wood again.Particularly can make a large amount of small diameter bamboo resources obtain reasonable use.Particularly it all needs then just can be pressed into sheet material through cuing open the formation unit that working angles such as the thin bamboo strip, flaking, rotary-cut are processed into specific modality unlike the bamboo wood in the above-mentioned various bamboo boards, but not having working angles basically, production technology and material and application etc. have its uniqueness.

Although above-mentioned all kinds of bamboo board has obtained extensive use, products such as present plastics coated ply-bamboo bamboo offset plate, tangential thin bamboo strips used for weaving curtain glued board, bamboo mat glued board, not only surface state is relatively poor, and the demoulding during especially for the false work template is difficult; The recombined bamboo plate product is then all the more so, and many, the coarse injustice in surface fiber space, a small amount of transverse fiber influence the perfectly straight characteristics of whole rift grain, when being used in building template also the adhesion effect because of the surface be difficult to the smooth demoulding.

The utility model content

At above-mentioned situation, the utility model will provide a kind of improvement structure, and the bamboo board that promptly has the composite skins structure to solve the deficiency of present all kinds of bamboo boards, makes it have even more ideal effect and wider application.

The utlity model has the bamboo board of composite skins structure, be the bamboo wood flitch material that extends with the plane as core structure, and be coated with the paint structure layer that contains the adhesive surface layer at least respectively in its two sides, as all kinds of phenolic resin glue dope layers commonly used etc.Wherein said bamboo wood flitch material core structure, can use the bamboo lumber of all kinds of forms such as above-mentioned existing plastics coated ply-bamboo bamboo offset plate, tangential thin bamboo strips used for weaving curtain glued board, bamboo mat glued board, recombined bamboo plate, its thickness can be decided according to the field and/or the needs that use.Said adhesive surface layer can be releasing coating or Organic fluoride release coating, is solvent-borne type or water paint, solidifies at low temperatures or drying, adheres to one deck adherent layer after the film forming on sheet material equably, can lower the surface tension of product effectively.

On the said structure basis, in said this paint structure layer, between core structure and adhesive surface layer, can also be provided with again as the one deck at least in the middle of coupling layer, putty bottom and the decorative layer etc.Wherein, said coupling layer can for as commercially available KH-570, silicone based coupling agents commonly used such as 590, help to improve each layer structure, particularly the binding ability between the heterogeneity material layer; The putty bottom can use and paint supporting various putty, as the oil putty atom ash of unsaturated polyester resin, aqueous putty etc., the hole that can be used for the closed material surface element, the use amount of minimizing surface material improves surface material service efficiency and surfacing, compactness; Decorative layer can be skin of paints such as the mixed paint of usefulness as usual or varnish.According to different applications and/or instructions for use, concrete version can have multiple different selection.For example:

As the case may be, said this paint structure layer can adopt and be followed successively by coupling layer, putty bottom, decorative layer and adhesive surface layer from inside to outside.Or be followed successively by putty bottom, decorative layer and adhesive surface layer from inside to outside, and also can be to be followed successively by decorative layer and adhesive surface layer from inside to outside, it is multi-form also to be followed successively by coupling layer and adhesive surface layer etc. from inside to outside.
