Abstract

A process for making a solid component out of recycled paint sludge is provided. The process can include providing a paint sludge and providing a second material. Thereafter, the paint sludge and the second material are mixed to produce a paint sludge-second material mixture. The paint sludge-second material mixture is processed in order to produce a polymer containing precursor. The processing can include granulating or densifying the paint sludge-second material mixture. After the precursor has been produced, it can be placed within a molding machine and a solid component is molded. The molding machine can be an injection molding machine, an extrusion molding machine or a blow molding machine.

Claims (16)

1. A process for making a solid component out of recycled paint sludge, the process comprising:

providing paint sludge;

providing a second material in the form of a recycled polymer filter media;

mixing the paint sludge with the second material to produce a paint sludge-second material mixture;

processing the paint sludge-second material mixture, the processing selected from the group consisting of granulating and densifying, the processing producing a precursor made from recycled paint sludge;

placing the precursor in a molding machine, the molding machine selected from the group consisting of an injection molding machine, an extrusion molding machine a blow molding machine, a thermal blow molding machine, a thermal form molding machine and compression molding machine; and

molding a solid component from the precursor.

2. The process of claim 1 , wherein the paint sludge is from an oil-based paint.

3. The process of claim 1 , wherein the paint sludge is from a water-based paint.

4. The process of claim 1 , wherein the paint sludge-second material mixture has a paint sludge content of between 1 to 99 weight percent.

5. The process of claim 4 , wherein the paint sludge content is between 20 to 80 weight percent.

6. The process of claim 5 , wherein the paint sludge content is between 30 to 70 weight percent.

7. The process of claim 1 , wherein the solid component has a density of greater than 80 percent of theoretical density.

8. The process of claim 7 , wherein the solid component has a density of greater than 85 percent of theoretical density.

9. The process of claim 1 , wherein the paint sludge is obtained from paint used to paint a motor vehicle.

10. The process of claim 1 , wherein the paint sludge is obtained from paint used to paint a motor vehicle on an automotive assembly line.
