Hard PVC stone plastic floor is because its plasticizer loading is low and its performance of expanding with heat and contract with cold is traditional semi-rigid PVC floor 1/2, just it is being subject to the favor of more and more consumers on the market.Existing PVC stone plastic floors available on the market are one kind with PVC Resin-oatmeal, calcium carbonate, stabilizer, lubricant, toughener are main material, using the disposable compound color film of SPC continuous lines and resistance to Grind the hard floor of layer.The technique has the features such as high degree of automation, process is few.

But the PVC stone plastic floors of existing SPC extrusion line production have the disadvantage that：Surface abrasion resistance sex expression is general；Decoration Emboss that single and its depth is partially shallow compared with conventional thermocompression technique productions product and its three-dimensional sense and fidelity have partial loss, it is impossible to full Expectation and demand of the sufficient existing market major part consumer to the apparent effect of product；Product feel is too poor, loses PVC bullets substantially Maximum resilient characteristic possessed by property floor.

Utility model content

The purpose of this utility model is to provide a kind of PVC stone plastic floors, which has surface abrasion resistance good and feel The advantages of good.

Technical solution is used by the utility model solves its technical problem：

A kind of PVC stone plastic floors, the PVC stone plastic floors are combined by wearing layer, decorative layer and base's hot pressing, institute It states base to be combined by middle level, stone molding base layer and bottom hot pressing, the middle level is adjacent with decorative layer, and stone molding base layer is located at Centre, bottom are located at the bottom of entire PVC stone plastic floors；The overall thickness of PVC stone plastic floors is 4.0-10.0mm, wearing layer Thickness is 0.1mm-1mm, and intima-media thickness 0.5-2.0mm, the thickness of stone molding base layer is 2.0-6.0mm, and underlayer thickness is 0.5-2.0mm.Intima-media thickness is preferably 0.7-1.5mm, and underlayer thickness is preferably 0.7-1.5mm, and stone molding base layer thickness is preferred For 3.0-5.0mm.

Preferably, wearing layer is the coat containing inorganic filler particle, inorganic filler particle is that have at least 0.1mm The ceramic particle of particle mean size.

Preferably, the surface of wearing layer is equipped with ultraviolet-curing paint layer.Ultraviolet-curing paint layer can improve ground The performances such as the glossiness of plate surface, enhancing floor surface are wear-resisting, scratch resistance or mould proof, resistant, antibacterial.

Preferably, middle level and bottom are the polyvinyl chloride resin composite bed by rolling process four-roll calendaring machine-shaping.

Preferably, stone molding base layer is the polyvinyl chloride resin composite bed by extrusion molding machine-shaping.

The PVC stone plastic floors of the utility model are by wearing layer, decorative layer, middle level (A), stone molding base layer, bottom (A) hot pressing Composite molding, the utility model structure are referred to as ABA structures.The main component of decorative layer is polyvinyl chloride resin, and the surface of decorative layer prints Brushed with decorative pattern or pattern.

The beneficial effects of the utility model are：The PVC stone plastic floors of the utility model have excellent surface abrasion resistance, together When, because the PVC stone plastic floors of the utility model have been superimposed elastic PVC grounds (in the utility model above and below stone molding base layer For middle level and bottom), it can reach the comfortable feel consistent with common PVC resiliently-mounted floor (abbreviation LVT).
