Description
Technical Field
The application relates to the technical field of wood boards, in particular to a green floor base material.
Background
The multilayer wood composite base material is a traditional wood plate and comprises three layers, five layers, seven layers, eleven layers and other structures, wherein the five-layer structure has relatively good solid wood characteristics (texture and foot feel) and composite material characteristics (stability) due to the moderate number of layers. The five-layer wood composite base material in the prior art is obtained by transversely and longitudinally staggering, laminating and compounding five wood veneer layers with the same or different materials. According to the basic design principle of the multilayer wood composite base material, the transversely arranged veneer layers drag the longitudinally arranged veneer layers, and relatively good material dimensional stability can be obtained.
When the multilayer wood composite base material is longitudinally cut and/or a long-edge lock catch structure is manufactured, the cutting surface of the transversely arranged veneer layer is a fiber section of the multilayer wood composite base material, so that the damage of wood is easy to occur during long-distance cutting, saw cutting dust larger than that of cut along grains is generated, and the implementation of green building materials is not facilitated. This phenomenon is more pronounced in a five-layer structure because the individual transversely disposed veneer layers in a five-layer structure need to have a certain thickness to provide sufficient traction for the longitudinally disposed veneer layers.
SUMMERY OF THE UTILITY MODEL
The present application aims to solve the above technical problems and provides a green floor base material.
For realizing above-mentioned purpose, the application discloses green floor substrate includes slim decorative layer, first veneer layer, intensity layer, second veneer layer, the third veneer layer that the fibre direction all followed the length direction overall arrangement of this floor substrate from top to bottom in proper order, the intensity layer is the heavy bamboo layer of carbomorphism.
In a preferred embodiment, the first veneer layer, the second veneer layer, and the third veneer layer are veneer layers of the same material.
As a preferred embodiment, the first veneer layer, the second veneer layer, and the third veneer layer are one of beech veneer layer, poplar veneer layer, or birch veneer layer.
As a preferred embodiment, the thickness of the strength layer is 30-50% of the total thickness of the flooring substrate.
In a preferred embodiment, the thickness of the thin decorative layer is 0.6mm, the thickness of the second veneer layer is 0.6 to 1.2mm, the remaining thickness is the thickness of the first veneer layer and the third veneer layer, and the thicknesses of the first veneer layer and the third veneer layer are equal.
As a preferred embodiment, the total thickness of the green floor substrate is 6 to 20 mm.
In a preferred embodiment, the first veneer layer has a plurality of balancing grooves formed on a surface thereof to be bonded to the strength layer, the balancing grooves being arranged along a longitudinal direction of the flooring substrate.
In a preferred embodiment, the balance groove is an embossed groove.
In a preferred embodiment, the depth of the balancing groove is 1 to 3 mm.
In a preferred embodiment, the width of the balancing groove is 2 to 6 mm.
By the structure, the layout directions of the five material layers are all arranged along the length direction of the green floor base material, so that the longitudinal cutting is always along the grain cutting, the cutting damage (such as edge breakage and corner breakage) of the material is not easy to occur, the cutting dust is relatively small, and the floor base material is relatively green; meanwhile, the carbonized heavy bamboo layer is arranged in the central layer of the five-layer structure, so that the carbonized heavy bamboo layer can be used as a thickness reference layer of the five-layer structure, and the problem of size stability caused by the five-layer same-direction fiber structure can be effectively solved.
Furthermore, the first to third veneer layers are made of the same material, so that the problem of dimensional stability caused by the five layers of the same-direction down-fiber structure can be solved. Meanwhile, the materials of the first veneer layer, the second veneer layer and the third veneer layer are fast-growing materials with soft texture of beech, poplar or birch, so that the hard texture of the carbonized heavy bamboo layer can be counteracted to a certain degree, and the materials have the relative solid wood texture of a five-layer structure in the prior art.
Particularly, the material layers (the first veneer layer and the third veneer layer) which have certain thickness and relatively soft texture are arranged on the upper part and the lower part of the strength layer, so that the hard texture of the carbonized heavy bamboo layer is counteracted in a sandwich mode, and the five-layer structure in the prior art has the relatively solid wood texture. Meanwhile, the thickness relationship of the two structural layers above the strength layer is that the thickness of the thin decoration layer is smaller, the thickness of the first veneer layer is thicker, and the thickness relationship of the two structural layers below the strength layer is that the thickness of the second veneer layer is smaller, and the thickness of the third veneer layer is thicker, so the five-layer structure of the technical scheme is not a symmetrical structure taking the strength layer as a reference. The floor has the advantages that the relatively thick coating layer is arranged on the surface of the floor substrate, so that the probability of moisture exchange between the surface of the floor substrate and the outside is relatively low, the moisture exchange amount is relatively small, the relatively thick first veneer layer can provide a relatively soft pressing surface for the thin decorative layer, and the smooth attachment of the thin decorative layer can be effectively ensured; the bottom surface of floor substrate generally only sets up thinner coating to there is the risk of bigger absorption cement ground aqueous vapor, relatively thinner second veneer layer can play the cushioning effect for the combination between third veneer layer and the intensity layer, comparatively effectual avoiding because of the size change of third veneer layer the problem of coming unstuck between two cementing layers that cause.
Furthermore, through the setting of equalizing groove, split into a plurality of strip cemented surfaces with the cemented surface of first veneer layer and strengthening layer, can further improve the stability of first veneer layer. In particular, the balancing groove is formed by embossing, which has two advantages over milled grooves: firstly, dust generated in the groove making process is reduced, and green production is facilitated; and secondly, the material at the position where the balance groove is formed is crushed and compressed, and after the first veneer layer absorbs moisture, the material used for crushing and compressing at the position of the balance groove rebounds to delay the dimensional change in the width direction, so that the problem of dimensional stability caused by a five-layer homodromous fiber structure is solved.
