Embodiment 1

[0035] 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.

[0036] 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 to 85°C, and becomes viscoelastic at 130°C , 160~180℃ began to change into a viscous flow state. When using traditional hot-pressing technology to produce PVC stone-plastic flooring, the heat is easily di...

Embodiment 2

[0040] 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

[0042] 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 stone plastic floor, and belongs to the field of floors. The stone plastic floor comprises a decorative layer, a PVC stone-plastic base layer and a balance layer from top tobottom sequentially, and heat insulation layers are separately arranged on the upper and lower surfaces of the PVC stone-plastic base layer. The preparation method comprises the following steps of a,mixing and heating of raw materials; b, formation of pores; c, extrusion molding; and d, cooling molding. According to the stone plastic floor, the deflect that the PVC stone-plastic floor produced byan existing hot-pressing process is prone to deforming and warping is overcome, the product deformation and warping defects caused by the high temperature of the PVC stone-plastic base layer during hot pressing are effectively overcome, and the qualified rate of the products is improved.

Description

[0001] The patent application of the present invention is a divisional application with the application number: 2017109457711. The application date of the original application is: 2017-10-11. The name of the invention is: a PVC stone-plastic floor resistant to processing and deformation. technical field [0002] The invention relates to a PVC stone-plastic floor, more specifically, to a stone-plastic floor. Background technique [0003] In the production process of the existing PVC multi-layer composite flooring, different sheets need to be stacked and paved on the hot-pressed formwork, and then pushed into the flat-bed hot press machine for hot-pressing and compounding into one. Regarding the use of hot-pressing technology to produce PVC stone There are a large number of related patent disclosures in the prior art for the technical solution of plastic flooring, such as patent publication number: CN 105908946A, publication date: August 31, 2016, and the name of the invention ...
