Emulsions with polymerized oils & methods of manufacturing the same

Abstract

Described herein is an emulsion for use in asphalt rejuvenation applications, comprising an oil phase comprising (1) a polymerized oil comprising a polymeric distribution having about 2 to about 80 wt % oligomer content, a polydispersity index ranging from about 1.0 to about 5.0, and sulfur content less than about 8 wt %; and (2) an aqueous phase, comprising a surfactant. The emulsion may be incorporated into asphalt paving, roofing, and coating applications and especially aged or recycled asphalt thereby obtaining rejuvenated asphalt.

   (b) An aqueous phase, comprising a surfactant.   
     
     
         2 . The emulsion of  claim 1 , wherein the oil phase further comprises a biorenewable oil, a previously modified, or functionalized oil. 
     
     
         3 . The emulsion of  claim 1 , wherein the aqueous phase further comprises polymers and/or thickeners. 
     
     
         4 . The emulsion of  claim 1 , wherein the polymerized oil is derived from a starting oil material isolated from plants, animals, or algae. 
     
     
         5 . The emulsion of  claim 4 , wherein the starting oil material is selected from the group consisting of palm oil, sunflower oil, corn oil, soybean oil, canola oil, rapeseed oil, linseed oil, tung oil, castor oil, tall oil, cottonseed oil, peanut oil, safflower oil, corn stillage oil, and combinations, distillates, derivatives, and crude streams thereof. 
     
     
         6 . The emulsion of  claim 5 , wherein the polymerized oil is an alkyl ester of one or more of the starting oil materials. 
     
     
         7 . The emulsion of  claim 4 , wherein the starting oil material is selected from the group consisting of animal fat, lecithin (phospholipids), and combinations, distillates, derivatives, and crude streams thereof. 
     
     
         8 . The emulsion of  claim 1 , wherein the polymerized oil is derived from a starting oil material of free fatty acids and distillate streams thereof. 
     
     
         9 . The emulsion of  claim 1 , wherein the polymerized oil is derived from a starting oil material selected from the group consisting of methyl, ethyl, propyl, and butyl esters, and combinations thereof. 
     
     
         10 . The emulsion of  claim 1 , wherein the polymerized oil is derived from a starting oil material selected from diol and triol esters, and mixtures and derivative streams thereof. 
     
     
         11 . The emulsion of  claim 1 , wherein the polymerized oil is derived from a starting oil material that has been previously modified. 
     
     
         12 . The emulsion of  claim 1 , wherein the polymerized oil is derived from a starting oil material selected from the group consisting of triacylglycerides, diacylglycerides, monoacylgyclerides, and combinations thereof. 
     
     
         13 . The emulsion of  claim 1 , wherein the polymerized oil is derived from a starting oil material comprising recovered corn oil. 
     
     
         14 . The emulsion of  claim 1 , wherein the polymerized oil is derived from a starting oil comprising a partially hydrogenated oil. 
     
     
         15 . The emulsion of  claim 1 , wherein the oil phase further comprises an asphalt binder. 
     
     
         16 . The emulsion of  claim 15 , wherein the oil phase comprises about 0.1 to about 100 wt % polymerized oil. 
     
     
         17 . The emulsion of  claim 1  wherein the oil phase makes up about 15-85 wt % of the emulsion. 
     
     
         18 . A method comprising applying the emulsion of  claim 1  to an existing pavement surface. 
     
     
         19 . A method comprising applying the emulsion of  claim 1  to treat RAS or RAP and further mixing the treated RAS or RAP with virgin asphalt thereby obtaining a rejuvenated asphalt blend. 
     
     
         20 . Use of the emulsion of  claim 1  as part of a cold patching material, a high performance cold patch or cold mix application that contains recycled asphalt thereby obtaining treated RAS or RAP.
