AI Technical Summary

Benefits of technology

This new method allows for creating a durable surface that can be used on both indoor or outdoor surfaces without any adhesive residues like traditional methods such as cementation. It also includes an improved design by adding layers made from different materials together instead of just one material altogether. Overall, this innovative technique makes it more efficient than existing techniques while reducing costs associated therewith.

Problems solved by technology

This patented technical problem addressed in this patents relates to producing complex-made pvc floorings that are safe for human beings without causing environmental concerns or negative side effects such as being bad at home due to excessive use of adhesives like gumming agents.

Embodiment 1

[0049] Such as figure 1 and figure 2 As shown, a double-layer co-extruded composite stone-plastic PVC floor, from top to bottom is wear-resistant layer 1, printing layer 2, stone-plastic layer 3 and PVC foam sound-absorbing layer 4, wherein stone-plastic layer 3 and PVC foam The foam sound-absorbing layer 4 is co-extruded to form a stone-plastic PVC co-extrusion layer, the above-mentioned printing layer 2 is hot-pressed on the stone-plastic layer 3 , and the wear-resistant layer 1 is hot-pressed on the printing layer 2 .

[0050] Among them, the stone plastic layer 3 is a non-foaming material, including the following components in parts by weight: 45 parts of PVC, 120 parts of stone powder (light calcium or heavy calcium or composite calcium), 5 parts of calcium zinc stabilizer, polyethylene glycol 1 part of distearate (G60), 1 part of PE wax, 5 parts of chlorinated polyethylene (CPE), 3 parts of ACR impact modifier.

[0051] The PVC foam sound-absorbing layer 4 contains th...

Embodiment 2

[0062] The structure of each layer of this embodiment is the same as that of Embodiment 1. The stone-plastic layer 3 is a micro-foaming material, including the following components in parts by weight: 75 parts of PVC, 130 parts of stone powder (light calcium or heavy calcium or composite calcium), 0.8 parts of foaming agent (wherein azo foaming 0.4 parts of sodium bicarbonate foaming agent), 8 parts of foam regulator, 6 parts of calcium zinc stabilizer, 1 part of polyethylene glycol distearate, 1 part of PE wax, 6 parts of chlorinated polyethylene parts, ACR impact modifier 3 parts, chlorinated polyvinyl chloride 6 parts.

[0063] The other raw material formulas and preparation methods and steps are the same as in Example 1, and will not be described in detail here.

[0064] The double-layer co-extruded composite stone-plastic PVC floor of this embodiment has low production cost, good stability, and good anti-sag performance. There is a PVC foam sound-absorbing layer at the b...

Embodiment 3

[0066] Such as image 3 , Figure 4 and Figure 5 As shown, a three-layer co-extruded composite stone-plastic PVC floor, from top to bottom is a wear-resistant layer 1, a printing layer 2, a PVC primer layer 5, a stone-plastic micro-foaming layer 6 and a second PVC foaming sound-absorbing layer. Layer 7, wherein the PVC primer layer 5, the stone-plastic micro-foaming layer 6 and the second PVC foam sound-absorbing layer 7 are co-extruded to form a stone-plastic PVC co-extrusion layer, and the printing layer is hot-pressed on the stone-plastic PVC co-extrusion layer , the wear-resistant layer is heat-pressed on the printing layer.

[0067] The PVC primer layer 5 contains the following components in parts by weight: 100 parts of PVC, 550 parts of stone powder, 1.5 parts of calcium zinc stabilizer, 35 parts of plasticizer, and 1 part of PE wax.

[0068] The stone plastic micro-foaming layer 6 contains the following components in parts by weight: 75 parts of PVC, 130 parts of s...

Abstract

The invention relates to a stone-plastic polyvinyl chloride (PVC) floor. A co-extruded composite stone-plastic PVC floor sequentially comprises an abrasion-resistant layer, a printed layer and a stone-plastic PVC co-extruded layer from top the bottom. The printed layer is hot-pressed on the stone-plastic PVC co-extruded layer. The abrasion-resistant layer is hot-pressed on the printed layer. The stone-plastic PVC co-extruded layer can be formed by co-extruding a stone-plastic layer and a PVC foam sound-absorption layer and can also be formed by co-extruding a PVC bottom material layer, a stone-plastic micro foam layer and a second PVC foam sound-absorption layer. According to the co-extruded composite stone-plastic PVC floor, the stone-plastic PVC co-extruded layer is produced through the co-extrusion technique, then the printed layer and the abrasion-resistant layer are attached through the hot pressing technique, and then the co-extruded composite stone-plastic PVC floor is formed; glue is not needed in the whole production process, so that the production cost is greatly reduced, the harm to the body health of workers is reduced, and the quantity of released volatile organic compounds (VOC) in the product using process is greatly reduced; and meanwhile, a good silencing effect is achieved.
