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

1 . A flooring material comprising:
a plasticizer; fibers comprising at least one type of inorganic fibers or at least one type of organic fibers; and a thermoplastic resin, wherein the fibers have an alignment.

2 . The flooring material according to claim 1 , wherein the plasticizer and the fibers have polarity.

3 . 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.

4 . The flooring material according to claim 1 , wherein the 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.

5 . The flooring material according to claim 1 , wherein the thermoplastic resin comprises at least one selected from the group consisting of polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polyvinylidene fluoride (PVF), chlorinated polyvinyl chloride (CPVC), polyvinylalcohol (PVA), polyvinylacetate (PVAc), polyvinylbutyrate (PVB), polyethylene (PE), polypropylene (PP), and combinations thereof.

6 . The flooring material according to claim 1 , wherein the plasticizer comprises at least one selected from the group consisting of diisononylphthalate (DINP), dioctyl terephthalate (DOTP), dioctylphthalate (DOP), dioctyladipate (DOA), and combinations thereof.

7 . The flooring material according to claim 1 , wherein the inorganic fibers comprise glass fibers or ceramic fibers.

8 . The flooring material according to claim 1 , wherein the inorganic fibers have a diameter of about 2 μm to about 6 μm.

9 . The flooring material according to claim 1 , wherein the inorganic fibers have a length of about 1 mm to about 3 mm.

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

11 . The flooring material according to claim 1 , wherein the organic fibers have a diameter of about 2 μm to about 20 μm.

12 . The flooring material according to claim 1 , wherein the organic fibers have a length of about 3 mm to about 50 mm.

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

14 . The flooring material according to claim 13 , 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.

15 . The flooring material according to claim 13 , wherein the fillers comprise at least one selected from the group consisting of calcium carbonate, talc, fly ash, blast-furnace slag, and combinations thereof.

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

17 . A method for manufacturing a flooring material, comprising:
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.

18 . The method according to claim 17 , wherein the liquid plasticizer and the fibers have polarity.

19 . The method according to claim 17 , wherein the first mixture is agitated at a speed of about 5 rpm to about 100 rpm.

20 . The method according to claim 17 , wherein thermo-compression of the third mixture are performed such that the fibers have an alignment.
