Embodiment 1

[0040] combine figure 1 , the stone-plastic floor with good dimensional stability in this embodiment includes a surface plate 1, a buffer layer 2 and a base plate 3, the surface plate 1 and the base plate 3 are connected by a buffer layer 2, and the buffer layer 2 is a technical wood layer, a non-woven One of the fabric layer and the glass fiber layer or a combination of two or a combination of the three. Specifically, in this embodiment, the buffer layer 2 is only a technical wood layer, and the thickness of the technical wood layer is 0.3-0.4 mm. The substrate 3 is a PVC stone-plastic board. The surface board 1 includes wood grain paper, the surface of the wood grain paper is covered with a wear-resistant and fireproof layer, and the wood grain paper and the wear-resistant fireproof layer together form the surface board 1 . Specifically in this embodiment, the wear-resistant and fire-resistant layer is an aluminum oxide layer.

Embodiment 2

[0050] combine figure 2 , the good stone-plastic floor of dimensional stability of the present embodiment, its structure is basically the same as embodiment 1, and its difference is: in the concrete present embodiment, the thickness of technical wood layer is 0.4mm;

[0051] In the stone-plastic floor with good dimensional stability in this embodiment, the inside of the substrate 3 is provided with a through hole 4 along the length direction. There are multiple through holes 4, and the plurality of through holes 4 are arranged in parallel along the width direction of the substrate 3; It can effectively reduce the weight of the substrate 3, save the production cost, and play a buffer role when the substrate 3 is deformed due to uneven heating, and can absorb most of the deformation on the substrate 3, eliminate the internal stress on the substrate 3, and prolong the life of the substrate 3. Its service life effectively avoids the occurrence of floor deformation. It should be ...

Embodiment 3

[0053] combine image 3 , the stone-plastic floor with good dimensional stability in this embodiment has basically the same structure as in Embodiment 2, the difference is that the cross section of the through hole 4 in this embodiment is circular, and the through hole with a circular cross section 4 can maximize the contact area between the air and the inner wall of the through hole 4 , enhance the effect of convective heat transfer in the through hole 4 , and is more conducive to avoiding local thermal deformation of the substrate 3 .

Abstract

The invention discloses a stone-plastic floor good in size stability, and belongs to the field of floors. The stone-plastic floor comprises a surface plate and a base plate which are connected througha buffer layer. The buffer layer is one or a combination of two or three of a scientific wood layer, a non-woven fabric layer and a glass fiber layer. The base plate is a PVC stone-plastic plate. Thesurface layer comprises wood grain paper. The surface of the wood grain paper is covered with a wear-resistant fireproof layer. The buffer layer is a scientific wood layer. The PVC stone-plastic plate is a PVC stone-plastic base material. The PVC stone-plastic base material is prepared through the following steps of a, mixing and heating raw materials; b, generating air holes; c, conducting extrusion forming; d, conducting cooing forming. The defect that an existing composite floor is prone to cracks and not environmentally friendly is overcome.

Description

technical field [0001] The invention relates to a floor, more specifically, to a stone-plastic floor with good dimensional stability. Background technique [0002] In recent years, solid wood flooring, composite flooring, impregnated paper laminated wooden flooring (laminated flooring) and the like have been widely used as ground decoration materials for interior decoration. Solid wood flooring needs to use a large number of large-caliber logs as raw materials. Generally speaking, the wood utilization rate of solid wood flooring is only 30% to 40%. It needs to use high-quality solid wood that has been used for decades or even hundreds of years. Natural resources. Thereby, there is the problem that high-quality timber is in short supply, and timber utilization rate is not high. The consumption of a large amount of forest resources will lead to the destruction of the ecological environment, and this problem has increasingly attracted people's attention. And in use, solid wo...
