Abstract

A composition comprising recycled paint and a thermal shock resistant material, a method of making the composition, and a method of applying the composition to a surface to prevent crack or leakage.

First claim

The invention claimed is:

1. A sealant composition comprising from about 0.1% to about 2% by weight of carbon black as a viscosity enhancer of the sealant composition, from about 80 to 97% by weight of latex paint, and from about 3 to 20% by weight of a thermal shock resistant material, wherein % by weight is based on the total sealant composition, wherein the thermal shock resistant material is fiber glass, and further wherein the latex paint comprises a binder selected from the group consisting of acrylic polymer, polyvinyl acrylic polymer, styrene acrylic polymer, polyvinyl acetate polymer, styrene butadiene polymer, ethylene vinyl acetate copolymer, and any combination thereof.

2. The composition of claim 1 , wherein the latex paint ranges from about 85 to 94% by weight and the thermal shock resistant material ranges from about 5 to 15% by weight.

3. The composition of claim 1 , wherein the latex paint accounts for about 89.5% of the total weight of the composition, the thermal shock resistant material accounts for about 10%, and the viscosity enhancer accounts for about 0.5%.

4. The composition of claim 1 , further comprising one or more auxiliary agents selected from the group consisting of cellulose fiber, plasticizer, defoaming agent, emulsifier, coloring agent, viscosity enhancer, microbiocide, antioxidant, UV light stabilizer, and UV light absorber.

5. A method of preparing a sealant composition, wherein the sealant composition comprises from about 0.1% to about 2% by weight of carbon black as a viscosity enhancer of the sealant composition, from about 80 to 97% by weight of recycled paint, and from about 3 to 20% by weight of a thermal shock resistant material, wherein % by weight is based on the total sealant composition, wherein the thermal shock resistant material is selected from the group consisting of silica, silicate, fiber glass, mica, wollastonite, a carbon-based fiber, and any combination thereof, and further wherein the recycled paint comprises a binder selected from the group consisting of acrylic polymer, polyvinyl acrylic polymer, styrene acrylic polymer, polyvinyl acetate polymer, styrene butadiene polymer, ethylene vinyl acetate copolymer, and any combination thereof, comprising
providing a treated or untreated recycled paint; and
mixing the recycled paint with a thermal shock resistant material.

6. The method of claim 5 , wherein the thermal shock resistant material comprises at least one member selected from the group consisting of mica, wollastonite, and fiberglass.

7. The method of claim 5 , further comprising adding a coloring agent or a viscosity enhancer.

8. The method of claim 7 , wherein the coloring agent or viscosity enhancer is carbon black.

9. The method of claim 5 , further comprising adding one or more auxiliary agents selected from the group consisting of cellulose fiber, plasticizer, defoaming agent, emulsifier, coloring agent, viscosity enhancer, microbiocide, antioxidant, UV light stabilizer, and UV light absorber.

10. The method of claim 5 , wherein the recycled paint ranges from about 85 to 94% by weight and the thermal shock resistant material ranges from about 5 to 15% by weight in the composition.

11. The method of claim 5 , wherein the recycled paint accounts for about 89.5% of the total weight of the composition, the thermal shock resistant material accounts for about 10%, and the viscosity enhancer accounts for about 0.5%.

12. A sealant composition comprising about 0.5% by weight of carbon black as a viscosity enhancer of the sealant composition, about 89.5% by weight of latex paint, and about 10% by weight of a thermal shock resistant material, wherein % by weight is based on the total sealant composition, wherein the thermal shock resistant material is selected from the group consisting of silica, silicate, fiber glass, mica, wollastonite, a carbon-based fiber, and any combination thereof, and further wherein the latex paint comprises a binder selected from the group consisting of acrylic polymer, polyvinyl acrylic polymer, styrene acrylic polymer, polyvinyl acetate polymer, styrene butadiene polymer, ethylene vinyl acetate copolymer, and any combination thereof.

13. The composition of claim 12 , wherein the thermal shock resistant material is silica, silicate, or a combination thereof.

14. The composition of claim 12 , wherein the thermal shock resistant material is mica or wollastonite.

15. The composition of claim 12 , further comprising one or more auxiliary agents selected from the group consisting of cellulose fiber, plasticizer, defoaming agent, emulsifier, coloring agent, viscosity enhancer, microbiocide, antioxidant, UV light stabilizer, and UV light absorber.
