Patent number: 6103000Abstract: The invention relates to an improved surfactant mixture which permits use of lower concentrations of polyphenolics including natural vegetable polyphenolic extracts and/or synthetic phenolic resins to produce stable anionic slow-setting asphalt-in-water emulsion compositions suitable for use as pavement sealers and coatings. The polyphenolics are selected from natural vegetable polyphenolic extracts including Chestnut A, Chestnut N and Sumac-K10; or from synthetic phenolic resins including phenol-formaldehyde, resorcinol-formaldehyde and novolak resins; or mixtures thereof; in amounts of about 0.1% to 10% polyphenolics in the final emulsion, to form and stabilize the emulsion. The emulsions employ a surfactant mixture comprising a nonionic surfactant with a hydrophilic/lipophilic balance index of from about 16 to about 20, and an anionic lignin sulfonate, in amounts of about 0.1% to 3.0% surfactant mixture in the final emulsion. Optionally 0.02% to 2.00% w/w of sodium borate decahydrate may be included.Type: GrantFiled: December 31, 1997Date of Patent: August 15, 2000Assignee: Saramco, Inc.Inventor: Robert S. Custer
