Problems solved by technology

[0003] However, the PVC stone-plastic floor produced by the existing SPC extrusion line has the following disadvantages: 1. The product cannot be cooled in time, the shrinkage performance is not ideal and cannot be controlled by tempering process
2. The surface embossment is single and its depth is shallower than that of products produced by traditional hot-pressing technology, and its three-dimensional sense and fidelity are partially los

Embodiment 2

[0078] A kind of manufacture method of PVC stone-plastic floor, concrete steps are as follows:

[0079] 1. The preparation method of the middle layer and the bottom layer is as follows:

[0080] (1) The raw materials are automatically fed according to the ratio through the automatic metering system,

[0081] (2) After passing through a high-speed mixer, the stirring speed is 1200 rpm for 3 minutes, and the temperature of the material is controlled within the range of 90-110°C.

[0082] (3) Banbury internal mixing, time 3 minutes; Unloading, one roll and two rolls of the open mill, the temperature of the rolls is 160-180°C, wherein, the temperature of the first roll is 180°C, the temperature of the second roll is 175°C, and the temperature of the discharge roll 160°C.

[0083] (4) Roll out sheet by four-roll calendering, roll temperature is 150-170°C; cooling and forming, cutting according to required size to obtain middle layer and bottom layer.

Embodiment 3

[0107] A PVC stone plastic floor, the structure is as image 3 As shown, the PVC stone-plastic floor is formed by hot-pressing the wear-resistant layer 1, the decorative layer 3 and the base layer, and the base layer is formed by hot-pressing the middle layer 3, the stone-plastic substrate layer 4 and the bottom layer 5. The middle layer is adjacent to the decorative layer, the stone-plastic substrate layer is in the middle, and the bottom layer is at the bottom of the entire PVC stone-plastic floor. The surface of the wear-resistant layer is provided with an ultraviolet light curing coating layer 6 . The UV-curable coating layer can improve the glossiness of the floor surface, enhance the wear resistance, scratch resistance, mildew resistance, stain resistance, antibacterial and other properties of the floor surface. The main component of the decorative layer is PVC resin, and patterns or patterns are printed on the surface of the decorative layer.

Abstract

The invention relates to the technical field of floors, in particular to a PVC stone-plastic floor and a production method thereof. The PVC stone-plastic floor is formed by a wear-resistant layer, a decoration layer and a base layer through hot pressing composition, wherein the base layer is formed by a middle layer, a stone-plastic base material layer and a bottom layer through hot pressing composition, the middle layer is close to the decoration layer, the stone-plastic base material layer is located in the middle, and the bottom layer is at the bottom of the whole PVC stone-plastic floor; the middle layer comprises components in percentage by mass as follows: 12%-17% of PVC resin, 7%-11% of dioctyl terephthalate, 0.1%-0.3% of a stabilizer, 70%-80% of calcium carbonate and 0.05%-0.1% ofcarbon black; the bottom layer comprises components in percentage by mass as follows: 30%-40% of PVC resin, 7%-15% of dioctyl terephthalate, 0.3%-1.0% of a stabilizer, 50%-70% of calcium carbonate and0.02% of carbon black.

Description

technical field [0001] The invention relates to the field of floor technology, in particular to a PVC stone-plastic floor and a manufacturing method thereof. Background technique [0002] Due to its low plasticizer content and its thermal expansion and contraction performance is 1 / 2 of the traditional semi-rigid PVC floor, the rigid PVC stone-plastic floor is being favored by more and more consumers in the market. The PVC stone-plastic floor currently on the market is a hard floor with PVC resin powder, calcium carbonate, stabilizer, lubricant, and toughening agent as the main materials, and a one-time composite color film and wear-resistant layer of SPC continuous line. . The process has the characteristics of high degree of automation and less process. [0003] But the PVC stone-plastic floor that existing SPC extruding line produces has following shortcoming: one, product can not be cooled in time, shrinkage performance is not ideal and can not be controlled by temperin...
