Description

A kind of multi-layer composite floor

Technical field

This utility model relates to a kind of floor, particularly relates to a kind of multi-layer composite floor.

Background technology

Along with rapid economic development, the exploitation of timber resources is increasingly faster, and earth vegetation day fades Moving back, the living environment of the mankind is precarious.

And Flooring Industry is very big for the demand of timber, the most how to reduce in Flooring Industry The use of timber becomes the key solving environmental problem.But, in floor produces, timber There is again the characteristic being much difficult to substitute.

At present, have some producers have begun to use plastic material go replace timber, but they Integral plastics (or wood plastic synthetic material) is typically all used to make ground plate shape, this floor Intensity, quality feel etc. are many-sided all cannot the floor of when solid wood material.

Utility model content

The purpose of this utility model is, it is provided that a kind of multi-layer composite floor.This utility model can To efficiently reduce the use of timber resources, more energy-conserving and environment-protective, there is higher structure simultaneously Intensity and stability in the large.

For solving above-mentioned technical problem, the technical scheme that this utility model provides is as follows: Yi Zhongduo Layer composite floor board, is characterized in: include that PVC base layer, the upper surface of PVC base layer are provided with Dough cover layer, dough cover layer is provided with skin of paint, and described dough cover layer is veneer or bamboo skin, described dough cover It is provided with polyurethane adhesive layer between layer and PVC base layer.

In above-mentioned multi-layer composite floor, the lower surface of described PVC base layer is provided with 3mm～5mm EVA bottom.

In aforesaid multi-layer composite floor, the upper and lower surface of described PVC base layer is all provided with Having multiple V-groove along floor length direction, the combination being possible not only to increase materials at two layers is strong Degree, and the bulk strength on floor can be improved as stress groove, not only it is difficult to warpage, and And load capacity is greatly enhanced.

In aforesaid multi-layer composite floor, the opening angle of described V-groove is 25～50 °, The degree of depth is 1.5mm～2.5mm, and the spacing of each V-groove is 12mm～35mm, can be maximum Change and improve bond strength and bulk strength.

In aforesaid multi-layer composite floor, described PVC base layer is PVC foam material layer.

In aforesaid multi-layer composite floor, described dough cover layer with the thickness proportion of PVC base layer is 1: 3 to 1: 5.

Compared with prior art, this utility model, by using PVC as substrate layer, and uses Wooden or bamboo material is combined, and can obtain having higher structural strength and monolithic stability The floor of property.This utility model can reduce the use of timber, more energy-conserving and environment-protective.And Floor of the present utility model, relative to common composite floor board, has higher dimensional stability, no The situation of buckling deformation easily occurs.Additionally this utility model also has waterproof, quiet feature.

Accompanying drawing explanation

Fig. 1 is embodiment 1 structural representation of the present utility model；

Fig. 2 is embodiment 2 structural representation of the present utility model.

Detailed description of the invention

Below in conjunction with embodiment, this utility model is further described.

Embodiment 1: a kind of multi-layer composite floor, as shown in Figure 1: include PVC base layer 1, PVC The upper surface of substrate layer 1 is provided with dough cover layer 2, and dough cover layer 2 is provided with skin of paint 4, described Cortex 2 is veneer or bamboo skin, is provided with polyurethane between described dough cover layer 2 and PVC base layer 1 Adhesive linkage 3.The upper and lower surface of described PVC base layer 1 is equipped with multiple long along floor The V-groove 6 in degree direction.The opening angle of described V-groove 6 is 25～50 °, and the degree of depth is 1.5mm～2.5mm, the spacing of each V-groove 6 is 12mm～35mm.Described PVC base Sheet material layers 1 is PVC foam material layer.Described dough cover layer 2 and the thickness proportion of PVC base layer 1 It is 1: 3 to 1: 5.

The production method of aforesaid multi-layer composite floor, specifically includes following steps:

A, opposite cortex carry out surface carbonation, form the carburization zone of 0.2mm～0.3mm；

B, the dough cover of surface carbonation is placed in polyurethane serosity immersion 1～1.5 hour；

C, dough cover layer is taken out from polyurethane serosity, strikes off the residual polyurethane of wherein one side, Another side is viscous to be pressed on PVC base layer；

D, solidification polyurethane；

E, at dough cover layer surface-coated skin of paint.

Described PVC base layer is extruded by PVC material, and extruding obtains vertical snap close knot Structure.

After tested, floor of the present utility model, at six hours at 70 DEG C, then-18 DEG C Lower six hours, after returning room temperature, long limit size changing rate as little as less than 0.6%, minor face chi Very little rate of change as little as less than 0.15%, the warpage maximum curvature as little as 0.5% of length direction, width The warpage maximum curvature as little as 0.35% in direction.

2. 1 kinds of multi-layer composite floors of embodiment, as shown in Figure 2: include PVC base layer 1, PVC The upper surface of substrate layer 1 is provided with dough cover layer 2, and dough cover layer 2 is provided with skin of paint 4, described Cortex 2 is veneer or bamboo skin, is provided with polyurethane between described dough cover layer 2 and PVC base layer 1 Adhesive linkage 3.The lower surface of described PVC base layer 1 is provided with the EVA bottom 5 of 3mm～5mm. The upper and lower surface of described PVC base layer 1 is equipped with multiple V along floor length direction Type groove 6.The opening angle of described V-groove 6 is 25～50 °, and the degree of depth is 1.5mm～2.5mm, The spacing of each V-groove 6 is 12mm～35mm.Described PVC base layer 1 is sent out for PVC Foam material layer.Described dough cover layer 2 is 1: 3 to 1: 5 with the thickness proportion of PVC base layer 1.
