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

1 . A sealant composition comprising from about 80 to 97% by weight recycled paint, and from about 3 to 20% by weight of a thermal shock resistant material.

2 . The composition of claim 1 , wherein the recycled paint comprises recycled latex paint.

3 . The composition of claim 1 , further comprising a viscosity enhancer or a coloring agent.

4 . The composition of claim 3 , wherein the viscosity enhancer or the coloring agent is carbon black.

5 . The composition of claim 1 , 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.

6 . The composition of claim 3 , 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 or the coloring agent accounts for about 0.5%.

7 . The composition of claim 1 , where in the thermal shock resistant material comprises a silicon-based material, a carbon-based fiber, or a combination thereof.

8 . The composition of claim 1 , where in the thermal shock resistant material comprises a silicon-based material.

9 . The composition of claim 8 , wherein the silicon-based material comprises silica, silicate, or a combination thereof.

10 . The composition of claim 9 , wherein the silicate comprises mica or wollastonite.

11 . The composition of claim 8 , wherein the silicon-based material comprises fiberglass.

12 . 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.

13 . A method of treating a surface comprising applying to the surface a composition of claim 1 .

14 . The method of claim 13 wherein the surface is built from one or more materials selected from the group consisting of asphalt, asphalt shingles, galvanized steel, aluminum, paint, wood, masonry and brick.

15 . The method of claim 13 wherein the surface is a road surface.

16 . A method of preparing the composition of claim 1 , comprising
providing a treated or untreated recycled paint; and mixing the recycled paint with a thermal shock resistant material.

17 . The method of claim 16 , wherein the recycled paint comprises a recycled latex paint.

18 . The method of claim 16 , wherein the thermal shock resistant material comprises a silicon-based material, a carbon-based fiber, or a combination thereof.

19 . The method of claim 16 , wherein the thermal shock resistant material comprises at least one member selected from the group consisting of mica, wollastonite, fiberglass.

20 . The method of claim 16 , further comprising adding a coloring agent or a viscosity enhancer.

21 . The method of claim 20 , wherein the coloring agent or viscosity enhancer is carbon black.

22 . The method of claim 16 , 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.
