Specific embodiment

The utility model is explained in detail with reference to the accompanying drawing.

A kind of wooden face SPC latch floor as shown in Figure 1, including SPC substrate layer 2, wooden surface layer 1, balance layer 3, PE are quiet Sound bed course 4.It is and described firstly, the wooden surface layer 1 is pasted the upper surface of the SPC substrate layer 2 by PUR glue-line 6 SPC substrate layer 2 it is compound, the balance layer 3 is pasted below the SPC substrate layer 2 by PUR glue-line 6, with institute The SPC substrate layer 2 stated is compound, forms wooden surface layer 1, SPC substrate layer 2,3 three-layer composite board of balance layer；Secondly, by described above Three-layer composite board carry out lamination treatment so that wooden surface layer 1, SPC substrate layer 2, balance layer 3 closely fit to one piece；Again It is secondary, anti-scratch, Wear-resistant Treatment is carried out to the surface of the wooden surface layer 1, one layer is coated mainly in the wooden surface layer 1 UV solidification glue, UV solidification glue have a stronger anti-scratch, wearability, described anti-scratch, wearing layer with a thickness of 0.3mm~0.9mm, Then opening lock catch process is carried out to three-layer composite board, obtains wooden face SPC latch floor；Finally, to wooden face SPC latch floor Silence processing is carried out, the mute bed course 5 of one layer of PE is adhered to by hot melt adhesive layer 7 below the balance layer 3, is obtained described Wooden face SPC latch floor, one layer of mute bed course of PE is added below the wooden face SPC latch floor and is removed has reduction Outside the purposes of noise, also there is comfortable feel, have the function of damping.

In the application, SPC substrate layer 2 used in wooden face SPC latch floor is the Corvic by high-quality With the solid sheet material with high density, high microsteping reticular structure of marble powder synthesis, hardness is big, impact resistance, this SPC substrate To water without affinity, therefore dampness deformation will not occur as solid wooden floor board, roll up and stick up, crack, it will not be big because of humidity It goes mouldy, the coefficient of expansion is well below wooden boards.

In the application, wooden surface layer 1 used in wooden face SPC latch floor is preferably fast-growing solid wood musculus cutaneus, bamboo and wood face The solid wood musculus cutaneus that skin or other timber are made into.It is well known that solid wooden floor board has environmental protection, comfortable foot feeling, cool in summer and warm in winter etc. excellent Point, but solid wooden floor board raw material chooses harshness, materials are more, seriously affect the ecological balance, therefore fast-growing solid wood is made into solid wood Bamboo and wood musculus cutaneus and SPC substrate layer 2 after musculus cutaneus or processing are laminated to one piece, both can achieve excellent possessed by solid wooden floor board Point, and the ecological balance is maintained, production cost, and this fast-growing solid wood surface or the composite floor board in bamboo and wood face are reduced, is had The texture of natural solid wood or bamboo and wood greatly meets people to beautiful requirement.The fast-growing solid wood or bamboo and wood musculus cutaneus Thickness be preferably 0.6mm~2.5mm.

In the application, the material of the compound wooden surface layer in the upper layer of wooden face SPC latch floor is wooden boards, easily swollen It is swollen, and the coefficient of expansion of SPC substrate layer is well below wooden boards, it is during use, blocky because the coefficient of expansion is different Speed of expansion above and below floor is inconsistent, easily leads to floor deformation, dislocation, is not easy to conserve, therefore, in the SPC substrate layer Below set a layer equilibration layer 3, be consistent with the coefficient of expansion of wooden boards, make monolith floor in expansions such as heated, dampness During up and down be consistent, it is ensured that floor be not easy dislocation deformation, keep long-term stability.The material of the balance layer 3 Matter is wooden, preferably solid wood or bamboo and wood.

In conclusion on the one hand guaranteeing the stabilization on floor by the way that one layer of wooden balance layer is arranged below SPC substrate layer Property, the material of the solid wood musculus cutaneus of the material and SPC substrate layer of another aspect balance layer is consistent, it is ensured that monolith floor is protected up and down Hold the consistent coefficient of expansion, the material of the material of the balance layer and the solid wood musculus cutaneus can be fast-growing solid wood musculus cutaneus, bamboo The wooden musculus cutaneus that face side skin or other timber are made into.PUR glue described herein and hot melt adhesive are environment-friendlyadhesive adhesive, it is ensured that whole A floor has good environmental-protecting performance.The solid wood musculus cutaneus with a thickness of 0.6mm~2.5mm, solid wood surface skin thickness is set It sets and meets saving timber, and there are enough spaces, the solid wood surfaces for the surface treatment of later period progress solid wood musculus cutaneus The UV coating of epidermis layer with a thickness of 0.3mm~0.9mm, this anti-scratch, wear-resisting thickness condition meets business and uses solid wooden floor board Requirement, moreover it is possible to the place applied to some pairs of floor performance requirement harshnesses.In the PE that the lower section of solid wood substrate balance layer is equipped with Mute bed course both can also have comfortable feel to avoid the friction on floor and ground, collision, reduction noise.

It is emphasized that: the above is only the preferred embodiment of the present utility model, not appoints to the utility model What formal limitation, any simple modification made by the above technical examples according to the technical essence of the present invention, etc. With variation and modification, it is still within the scope of the technical solutions of the present invention.
