Abstract

The utility model relates to a wood stair composite step board wrapped by a painted wood veneer. The step board provided by the utility model comprises core materials which are mutually spliced in a toothing way and a main material glued at the periphery of the core materials. The wood stair composite step board provided by the utility model is characterized in that the outer surface of the main material is wrapped by a layer of painted wood veneer. The wood stair composite step board wrapped by the painted wood veneer has the beneficial effects that: leftover bits and pieces and materials with poor veins are fully used, waste of timber resources is greatly reduced, and the manufacturing cost is reduced; the core materials are mutually connected in a toothing way so as to effectively disintegrate internal hidden force of the stair step board, avoid bending deflection, natural cracking and the like of the stair step board and prolong the service life; and the painted wood veneer coated with hot-melting paint has extremely high flexibility and cracking resistance due to a resilient coating.

Description

A kind of compound step plate of Wooden stair of painting the veneer coating

Technical field

The utility model belongs to the composite board technical field, is specifically related to a kind of compound step plate of Wooden stair that veneer coats of painting.

Background technology

At present in similar technical field; The Wooden stair step plate mainly is to be formed by the cutting of monoblock log; Be cut into tread to the monoblock log today in that the human society timber resources sharply reduces, and a large amount of leftover pieces can't be fully utilized; Brought a large amount of wastes for limited timber resources, cost of material is high; Secondly, because the log quality is loose relatively, be prone to absorption, absorb moisture content; Not only moisture-sensitive also is prone to damaged by worms, and tread normally is fixed on the keel at two ends in addition; Middle load-bearing, its inner latent power can't limitedly be decomposed, so tread is along its length direction; Be very easy to occur bending and deformation, phenomenon such as natural cracking, influence is used.

Because traditional paint toughness is extremely low, it is crisp to be prone to.Therefore, all be to adopt the veneer material that section bar is coated in most cases, carry out the surface paint of veneer afterwards again, carry out eight processing steps at least: priming paint, curing, sanding, priming paint, curing, sanding, finish paint, curing.Revolutionary improvement takes place and adopt the hot melt lacquer that veneer will be coated.

The hot melt lacquer has the characteristics of PUR high tenacity, therefore, adopts paint veneer pliability and the resistance to cracking ability high because of flexible coating has after hot melt coats with lacquer application, is superior to these performances that veneer material plate itself is had.So when adopting the hot melt lacquer to carry out veneer behind the application paint as the section bar clad material, even coat the section bar of small radii, the surface behind the veneer paint can not produce the phenomenon of cracking or " white slight crack " yet.

Summary of the invention

The technical problem that the utility model solved is to provide a kind of and makes full use of waste material, is difficult for strain cracking, economical and practical, paint the compound step plate of Wooden stair that veneer coats.

For realizing above-mentioned purpose, the technical scheme that the utility model is taked is:

A kind of compound step plate of Wooden stair of painting the veneer coating; This step plate comprises each other the core material that is spliced by toe joint and the major ingredient that is connected to around the said core material, and it is characterized in that: the external surface at said major ingredient also is coated with one deck paint veneer.

Between said core material and the core material, be connected each other through the toe joint mode in the horizontal direction, connect mutually through glue between the vertical contact surface.

Also glued mutually between said major ingredient and the core material through glue.

Said paint veneer external surface is printed on pattern or decorative pattern, also is equipped with a UV top coat layer at the upper surface of the said paint veneer that is shaped on pattern or decorative pattern.

The pattern of said paint veneer external surface or decorative pattern adopt the application of hot melt lacquer.

Said paint veneer sticker is in the surface of said major ingredient.

Thickness≤the 2mm of said paint veneer.

The beneficial effect that the utlity model has is: make full use of the bad material of leftover pieces and texture, significantly reduced the waste of timber resources, reduced the cost of making; Be connected through the toe joint mode between the core material, effectively decomposed the latent power in inside of tread, avoided the phenomenons such as flexural deformation, natural cracking of tread, prolonged application life; Adopt paint veneer pliability and the resistance to cracking ability high after hot melt coats with lacquer application because of flexible coating has.

Description of drawings

Fig. 1 is the utility model: a kind of structural representation of painting the compound step plate of Wooden stair of veneer coating.

The specific embodiment

In order to make the utility model realize new technological means, creation characteristic, to reach purpose and be easy to understand understanding,, further set forth the utility model below in conjunction with concrete diagram with effect.

Embodiment: with reference to shown in Figure 1; A kind of compound step plate of Wooden stair of painting the veneer coating; This step plate comprises each other the core material 2 that is spliced by toe joint and the major ingredient 1 that is connected to around the core material 2, also is coated with one deck paint veneer 3 at the external surface of major ingredient 1.

Between core material 21 and the core material 22, be connected each other through the toe joint mode in the horizontal direction, on vertical contact surface, also glued joint mutually between core material 21 and core material 23, core material 22 and the core material 23 through environment-friendly type glue.

Core material 2 after handing-over accomplished compresses compacting, then with major ingredient 1 gluing around core material 2.

Paint veneer 3 external surfaces are printed on pattern or decorative pattern (indicating), also are equipped with a UV top coat layer (indicating) at the upper surface of the paint veneer 3 that is shaped on pattern or decorative pattern.

The pattern of paint veneer 3 external surfaces or decorative pattern adopt the application of hot melt lacquer.

Paint veneer 3 stickers are in the surface of said major ingredient.

Thickness≤the 2mm of paint veneer 3.

More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the manual that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
