Embodiment 1

[0044] The stable layer 101, the strength layer 102, and the elastic layer 103 use the components listed in Table 1-3.

[0045] In this embodiment, as attached figure 2 As shown, the manufacturing method of this floor comprises, at first according to the raw material in table 1, 3 and throwing A material in No. 1 extruder, and wherein the throwing amount of each raw material of A material is the throwing-in of elastic layer and stabilizing layer Half of the total amount; according to Table 2, put material B into the No. 2 extruder, and the amount of each raw material of material B is the amount of strength layer. The No. 1 extruder simultaneously extrudes the elastic layer and the stable layer of equal quality and thickness, and the No. 2 extruder extrudes the strength layer. Then it is extruded into the mold runner distributor, so that the strength layer is located between the elastic layer and the stable layer, and then enters the die for extrusion to form the SPC substrat...

Embodiment 2

[0048] The difference from Example 1 is that the proportions of the stable layer, the strength layer and the elastic layer are different, and the specific proportions are shown in Table 1-3.

Embodiment 3

[0050] The difference from Example 1 is that the proportions of the stable layer, the strength layer and the elastic layer are different, and the specific proportions are shown in Table 1-3.

Abstract

The invention belongs to the field of synthetic floors, and particularly relates to a co-extruded SPC stone-plastic floor. The co-extruded SPC stone-plastic floor comprises a stone-plastic base material layer forming a floor main body, a decoration layer arranged on the stone-plastic base material layer, a wear-resistant layer arranged on the decoration layer and a UV coating arranged on the wear-resistant layer. The stone-plastic base material layer is composed of an elastic layer, an intensity layer and a stable layer. The stone-plastic base material layer is formed through a co-extrusion mode. According to the co-extruded SPC stone-plastic floor, thermal expansion and contraction deformation can be ensured, other performances of the floor are not affected, and the cost is low.

Description

technical field [0001] The invention belongs to the field of synthetic floors, and in particular relates to a co-extruded SPC stone-plastic floor. Background technique [0002] Traditional ceramic flooring, solid wood flooring, and composite flooring have phenomena such as cold feet, easy deformation, and excessive formaldehyde, which can no longer meet people's requirements. There is an urgent need for a soft, non-deformable and environmentally friendly indoor floor. LVT floor, also known as PVC floor, came into being to meet people's needs; the main component of PVC floor is polyvinyl chloride material, which is widely used in all aspects of home and business because of its rich patterns and colors. LVT floor is a new type of light-weight floor decoration material that is very popular in the world today, also known as "light-weight floor". It is a popular product in Europe, America, Asia, Japan and South Korea. It has been popular abroad. Since it entered the Chinese mark...
