Abstract

A composite material includes a polymer matrix material and filler material that includes vitreous china. The composite material has a water absorption of less than about one percent. Such a composite material may be used in the production of articles such as sinks, bathtubs, shower receptors, and other articles that may benefit from low water absorption properties.

Claims (38)

1. A composite material comprising:

a polymer matrix material; and

a filler material comprising vitreous china;

wherein the composite material has a water absorption of less than about one percent.

2. The composite material of claim 1 , wherein the filler material comprises particles with a size in the range of between approximately 1 and 2000 micrometers.

3. The composite material of claim 1 , wherein the composite material comprises between about 10% and 70% by weight polymer matrix material and between about 30% and 90% by weight filler material.

4. The composite material of claim 1 , wherein the filler material further comprises sand.

5. The composite material of claim 4 , wherein the sand is recycled core sand.

6. The composite material of claim 1 , wherein the polymer matrix material comprises a polymer resin material or a mixture of polymer resin materials.

7. The composite material of claim 1 , wherein the vitreous china comprises:

between about 50% and 80% by weight SiO 2 ,

between about 10% and 30% by weight Al 2 O 3 ,

between about 0% and 4% by weight Na 2 O 3 ,

between about 0% and 4% by weight K 2 O,

between about 0% and 3% by weight TiO 2 , and

between about 0% and 5% by weight MgO.

8. The composite material of claim 1 , wherein the composite material has a hardness of between about 4 and 9 on the Moh's hardness scale.

9. The composite material of claim 1 , wherein the filler material has a water absorption of less than about 1%.

10. An article comprising a composition, the composition comprising:

a polymer matrix material; and

a filler material comprising vitreous china;

wherein the article has a water absorption of less than approximately one percent.

11. The article of claim 10 , wherein the article is a sink.

12. The article of claim 10 , wherein the article is a shower receptor, bathtub, countertop, or integrated top and bowl single structure.

13. The article of claim 10 , wherein the filler material comprises particles with a size in the range of about 1 to about 2000 micrometers.

14. The article of claim 10 , wherein the composition comprises between about 10% and 70% by weight polymer matrix material and between about 30% and 90% by weight filler material.

15. The article of claim 10 , wherein the filler material comprises sand.

16. The article of claim 15 , wherein the sand is recycled core sand.

17. The article of claim 10 , wherein the polymer matrix material comprises a polymer resin material or a mixture of polymer resin materials.

18. The article of claim 10 , wherein the vitreous china comprises:

between about 50% and 80% by weight SiO 2 ,

between about 10% and 30% by weight Al 2 O 3 ,

between about 0% and 4% by weight Na 2 O 3 ,

between about 0% and 4% by weight K 2 O,

between about 0% and 3% by weight TiO 2 , and

between about 0% and 5% by weight MgO.

19. The article of claim 10 , wherein the article has a hardness of between about 4 and 9 on the Moh's hardness scale.

20. The article of claim 10 , wherein the filler material has a water absorption of less than 1%.
