Abstract

Disclosed herein is a flooring material including: a plasticizer; fibers comprising at least one type of inorganic fibers or at least one type of organic fibers; and a thermoplastic resin. The fibers have an alignment. In addition, a method for manufacturing a flooring material is also disclosed. The method includes preparing a first mixture by mixing a liquid plasticizer with fibers comprising at least one type of inorganic fibers or at least one type of organic fibers; preparing a second mixture in which the fibers are dispersed in the liquid plasticizer by agitating the first mixture; preparing a third mixture by mixing the second mixture with a thermoplastic resin; and forming a floor material through thermo-compression of the third mixture.

First claim

The invention claimed is:

1. A flooring material, comprising:
a polar plasticizer;
polar fibers comprising aromatic polyamide fibers; and
a thermoplastic resin,
wherein the polar fibers have an alignment,
wherein the polar fibers are present in an amount of 0.1 parts by weight to 10 parts by weight based on 100 parts by weight of the thermoplastic resin,
wherein the polar plasticizer comprises dioctyl terephthalate (DOTP),
wherein the thermoplastic resin comprises polyvinyl chloride (PVC), and
wherein the aromatic polyamide fibers have a diameter of about 2 μm to about 20 μm and a length of about 3 mm to about 50 mm.

2. The flooring material according to claim 1 , wherein the plasticizer is present in an amount of 20 parts by weight to 30 parts by weight based on 100 parts by weight of the thermoplastic resin.

3. The flooring material according to claim 1 ,
wherein the polar fibers further comprises polar inorganic fibers, and
wherein the polar inorganic fibers comprise glass fibers or ceramic fibers.

4. The flooring material according to claim 1 , wherein the polar fibers further comprises inorganic fibers having a diameter of about 2 μm to about 6 μm.

5. The flooring material according to claim 1 , wherein the polar fibers further comprises inorganic fibers having a length of about 1 mm to about 3 mm.

6. The flooring material according to claim 1 , wherein the polar fibers further comprise at least one selected from the group consisting of nylon fibers, polypropylene (PP) fibers, and combinations thereof.

7. The flooring material according to claim 1 , further comprising: fillers.

8. The flooring material according to claim 7 , wherein the fillers are present in an amount of about 100 parts by weight to about 600 parts by weight based on 100 parts by weight of the thermoplastic resin.

9. The flooring material according to claim 7 , wherein the fillers comprise at least one selected from the group consisting of calcium carbonate, talc, fly ash, blast-furnance slag, and combinations thereof.

10. The flooring material according to claim 1 , wherein the flooring material has a thickness of about 2 mm to about 7 mm.

11. The flooring material according to claim 1 , wherein each strand of the polar fibers is dispersed throughout the thermoplastic resin.
