Abstract
Compounded polymeric compositions containing processed paint sludge putty as a replacement for polymeric components are provided. The paint sludge comprises from about 5 to 90% by weight of the total compounded polymeric composition and may be decatalyzed so that it contains uncured polymer for use in a variety of compositions including pressure sensitive sealants, caulking sealants, automotive sealants, polyvinyl chloride plastics, rubbers and asphalt cement coatings.
Claims16
A compounded polymeric composition comprising:
- a) at least one polymeric component selected from the group consisting of plasticizers, binders, tackifiers. modifiers, rubbers, resins, and mixtures thereof, and
- b) processed paint sludge putty containing uncured polymer, wherein said processed paint sludge putty is a replacement for at least a portion of said at least one polymeric component, wherein said paint sludge putty has been processed from raw paint sludge containing water, solvent and uncured polymer which has been agitated under a vacuum at a temperature of about 225.degree. F. such that a portion of the water and solvent is removed from said sludge;
- wherein said processed paint sludge putty comprises from about 20 to 50% by weight of the total compounded polymeric composition.
A compounded polymeric composition comprising:
- a) at least one polymeric component selected from the group consisting of plasticizers, binders, tackifiers, modifiers, rubbers, resins, and mixtures thereof, and
- b) processed paint sludge putty containing uncured polymer, wherein said processed paint sludge is a replacement for at least a portion of said at least one polymeric component, wherein said paint sludge putty has been decatalyzed by treatment with from about 0.1 to 10% of a base having a pH range of from 8-13.
A modified asphalt cement coating formed from processed paint sludge putty containing uncured polymer, wherein said paint sludge putty has been decatalyzed with a base, said coating comprising about 8% by weight paint sludge putty and about 92% by weight asphalt cement.
A compounded polymeric composition comprising:
- a) at least one polymeric component selected from the group consisting of plasticizers, binders, tackifiers, modifiers, rubbers, resins, and mixtures thereof, and
- b) processed paint sludge putty containing uncured polymer, wherein said processed paint sludge is a replacement for at least a portion of said at least one polymeric component, wherein said processed paint sludge putty comprises from about 20 to 50% by weight of the total compounded polymeric composition.
