Abstract

The present invention relates to transparent chips for artificial marble and artificial marble including the same. The transparent chips for artificial marble include (A) a halogenated epoxy acrylate resin and (B) metal fibers. The transparent chips are fabricated by adding metal fibers to a transparent resin. The transparent chips for artificial marble can implement both linear stripe patterns and three-dimensional effects inherent thereto, thereby providing an aesthetically pleasing appearance.

First claim

What is claimed is:

1. Transparent chips for artificial marble comprising a cured product of: about 100 parts by weight of (A) a halogenated epoxy acrylate resin; and about 1 part by weight to about 5 parts by weight of (B) metal fibers, wherein the transparent chips have a Barcol hardness of about 25 to about 35.

2. The transparent chips according to claim 1 , wherein the (A) halogenated epoxy acrylate resin has a weight average molecular weight of about 500 g/mol to about 3,000 g/mol.

3. The transparent chips according to claim 1 , wherein the metal fibers have a Barcol hardness of about 10 to about 40, an average length of about 1 mm to about 10 mm, and an average diameter of about 5 μm to about 20 μm.

4. The transparent chip according to claim 1 , wherein the metal fibers comprise at least one of aluminum fibers, nickel fibers, and aluminum/nickel alloy fibers.

5. Artificial marble comprising a cured product of: about 40 parts by weight to about 100 parts by weight of the transparent chips for artificial marble according to claim 1 ; and about 120 parts by weight to about 180 parts by weight of inorganic fillers, each based on about 100 parts by weight of a (meth)acrylate syrup, the (meth)acrylate syrup comprising about 1 wt % to about 30 wt % of a (meth)acrylate polymer and about 70 wt % to about 99 wt % of a (meth)acrylate monomer.

6. The artificial marble according to claim 5 , wherein the (meth)acrylate monomer is a (meth)acrylate monomer including at least one of a C 1 to C 20 aliphatic hydrocarbon group, a C 3 to C 20 cycloaliphatic hydrocarbon group, and a C 5 to C 20 aromatic hydrocarbon group.

7. The artificial marble according to claim 5 , wherein the inorganic fillers comprise at least one of calcium carbonate, aluminum hydroxide, silica, alumina, and magnesium hydroxide.

8. The artificial marble according to claim 5 , further comprising marble chips, wherein the marble chips further comprise at least one of general acrylate resin chips and unsaturated polyester chips.

9. The artificial marble according to claim 5 , wherein the artificial marble has a Barcol hardness of about 30 to about 40.

10. The transparent chip according to claim 1 , wherein the transparent chips have a Barcol hardness of about 25 to about 30.
