Abstract
The present application relates generally to bio-adhesive components isolated from bio-oil prepared from animal waste, methods of preparation of the bio-adhesive components and uses thereof. Such uses include, but are not limited to, asphalt bio-binders, bio-adhesion promoters, asphalt bio-rejuvenators, asphalt bio-extenders, bio-asphalt as well as uses in roofing, soil stabilization, crack and joint sealing and flooring adhesives.
Claims20
A bio-adhesive composition comprising a heavy liquid fraction and a bio-residue, wherein the composition has a viscosity of about 0.5 cP at 135° C., wherein said heavy liquid fraction and bio-residue are isolated from bio-oil produced from animal waste and wherein said bio-adhesive composition does not contain a light liquid fraction from said bio-oil.
A bio-adhesive composition comprising a heavy liquid fraction having a viscosity of between about 0.1 cP and about 0.5 cP at 135° C., wherein said heavy liquid fraction is isolated from bio-oil produced from animal waste and said bio-adhesive composition does not contain a light liquid fraction from said bio-oil.
A bio-adhesive composition comprising a bio-residue having a viscosity of at least about 0.4 cP at 135° C., wherein said bio-residue is isolated from bio-oil produced from animal waste, and wherein said bio-adhesive composition does not contain a light liquid fraction from said bio-oil.
