Abstract
Surface treatment compositions and their methods of preparation. Such surface treatment compositions can comprise a solid cross-linking agent and a water-soluble polymer. Such solid cross-linking agent can include a plurality of dialdehyde residues, and the water-soluble polymer can include a plurality of pendant groups capable of covalently bonding with the solid cross-linking agent. The surface treatment compositions can further comprise a fibrous material. Applications for such surface treatment compositions include soil erosion prevention, dust control, and landfill cover.
Claims30
A surface treatment composition comprising:
- (a) a solid cross-linking agent comprising a plurality of residues of a dialdehyde;
- and
- (b) a water-soluble polymer capable of covalently bonding with said solid cross-linking agent.
A surface treatment method comprising:
- (a) combining water and a surface treatment composition to thereby form an aqueous surface treatment mixture, wherein said surface treatment composition comprises:
- (i) a solid cross-linking agent comprising a plurality of residues of a dialdehyde, and
- (ii) a water-soluble polymer capable of covalently bonding with said solid cross-linking agent;
- and
- (b) applying at least a portion of said aqueous surface treatment mixture to a target area.
A method of making a surface treatment composition, said method comprising:
- (a) heating a mixture comprising water and a dialdehyde to remove at least a portion of said water thereby forming a solid cross-linking agent;
- and
- (b) combining at least a portion of said solid cross-linking agent with a water-soluble polymer capable of covalently bonding with said solid cross-linking agent.
