Problems solved by technology

[0009] The purpose of the present invention is to overcome the defect that the PVC stone-plastic floor produced by the existing hot-pressing process is prone to deformation and warping defects, and provides a PVC stone-plastic floor that is resistant to processing and deformation, which effectively avoids the PVC stone-plastic floor caused by PVC stone during hot pressing. Product deformation and warping defects caused by excessive temperature of the plastic base layer improve the product qualification rate

Embodiment 1

[0038] combine figure 1 , the anti-processing and deformation PVC stone-plastic flooring of the present embodiment includes a decorative layer 1, a PVC stone-plastic base layer 3 and a balance layer 4 from top to bottom, wherein the upper and lower surfaces of the PVC stone-plastic base layer 3 are respectively provided with The heat insulation layer 2, specifically in this embodiment, the heat insulation layer 2 is a material that can withstand a temperature above 100° C. for more than 10 seconds.

[0039] The molecular weight of industrially produced PVC is generally in the range of 50,000 to 110,000, with a large polydispersity, and the molecular weight increases with the decrease of the polymerization temperature; there is no fixed melting point, it starts to soften at 80-85°C, and becomes viscoelastic at 130°C , 160~180℃ began to change into a viscous flow state. When the traditional hot pressing process is used to produce PVC stone-plastic flooring, the heat is easily di...

Embodiment 2

[0043] The structure of the anti-processing and deformation PVC stone-plastic floor of this embodiment is basically the same as that of Embodiment 1, furthermore, the decorative layer 1 includes decorative paper, and the upper surface of the decorative paper is pasted with an aluminum oxide wear-resistant layer, wherein the aluminum oxide The two-aluminum wear-resistant layer has the advantages of super wear-resistant, high elasticity, super impact resistance, fire retardant, waterproof and moisture-proof, sound-absorbing and noise-proof, and realistic patterns.

Embodiment 3

[0045] The structure of the anti-processing and deformation PVC stone-plastic floor of this embodiment is basically the same as that of Embodiment 1, furthermore, the decorative layer 1 includes decorative paper, and the decorative paper is a decorative spray-coated paper whose upper surface is sprayed with aluminum oxide. The decorative spray paper coated with aluminum oxide on the surface is used as the decorative layer 1, which simplifies the processing technology of the PVC stone-plastic floor.

Abstract

The invention discloses a PVC stone-plastic floor capable of resisting to machining deformation, and belongs to the field of PVC stone-plastic floors. The PVC stone-plastic floor sequentially comprises a decorative layer, a PVC stone-plastic base layer and a balance layer from top to bottom; and thermal insulating layers are correspondingly arranged on the upper surface and the lower surface of the PVC stone-plastic base layer; the thermal insulating layers are made of materials which resist to the temperature of 100 DEG C or above for 10 seconds or above; and the thickness of each thermal insulating layer is greater than or equal to 0.2 mm. The PVC stone-plastic base layer is made of a PVC stone-plastic base material, and the PVC stone-plastic base material is prepared by adopting the following steps of a, raw material mixing and heating, b, pore generating, c, extrusion molding, and d, cooling molding. The PVC stone-plastic floor capable of resisting to machining deformation aims toovercome the defect of the product defect of deformation warping prone to occurring in a PVC stone-plastic floor produced by using an existing hot-pressing technology; and the PVC stone-plastic floorcapable of resisting to machining deformation effectively avoids the product defect of deformation warping caused by the excessively high temperature of the PVC stone-plastic base layer during hot pressing, and the product pass rate is increased.

Description

technical field [0001] The invention relates to a PVC stone-plastic floor, and more specifically relates to a PVC stone-plastic floor resistant to processing and deformation. Background technique [0002] With the development of society, various ground decoration materials and decoration products continue to appear. The products that everyone is more familiar with are: tiles, floor leather, solid wood flooring, composite wood flooring, etc., and their application scope involves all aspects of our lives. [0003] Among them, ceramic tiles have good wear resistance, waterproof, moisture-proof, anti-corrosion, and also have certain pressure resistance, hard texture, convenient material selection, and long service life. They can be widely used in various indoor environments and are deeply loved by consumers. It is also the most widely used. Floor leather, easy to lay, easy to scrub, light in weight, small in size, flexible in use, can be cut according to needs, and has strong ...
