Abstract

An additive formulation for lignocellulosic composites comprising a) a first aqueous emulsion comprising i) a component selected from the group consisting of petroleum wax, a triglyceride, and combinations thereof; and ii) a first anionic emulsifier; and b) a second aqueous emulsion comprising: i) a reaction product of I) a derivative of a polyol selected from the group consisting of saccharides, sugar alcohols, sugar acids, gluconic acids, and gluconic acid lactones; and II) a polyisocyanate; and ii) an emulsifier selected from the group consisting of a second anionic emulsifier, a non-ionic emulsifier, and mixtures thereof, is disclosed.

Claims (17)

1. A formulation comprising:

a) a first aqueous emulsion comprising

i) a component selected from the group consisting of petroleum wax, a triglyceride, and combinations thereof; and

ii) a first anionic emulsifier; and

b) a second aqueous emulsion comprising:

i) a reaction product of

I) a derivative of a polyol selected from the group consisting of saccharides, sugar alcohols, sugar acids, gluconic acids, and gluconic acid lactones; and

II) a polyisocyanate; and

ii) an emulsifier selected from the group consisting of a second anionic emulsifier, a non-ionic emulsifier, and mixtures thereof.

2. A formulation in accordance with claim 1 wherein the triglyceride is selected from the group consisting of soybean oil, rapeseed oil, sunflower oil, canola oil, safflower oil, menhaden oil, corn oil, olive oil, cacao oil, linseed oil, cottonseed oil, peanut oil, palm oil, jatropha oil, algal oil, castor oil, coconut oil, tallow, fish oil, chicken fat, lard, butter, and combinations thereof.

3. A formulation in accordance with claim 1 wherein the petroleum wax is a slack wax.

4. A formulation in accordance with claim I wherein the first and second anionic emulsifiers are the same or different and are selected from the group consisting of sodium lauryl sulfate, ammonium lauryl sulfate, sodium laureth sulfate, sodium myreth sulfate, sodium stearate, sodium lauryl sarcosinate, perfluorononanoate, perfluorooctanoate, and combinations thereof.

5. A formulation in accordance with claim 1 wherein the polyol is selected from the group consisting of glucose, glyceraldehyde, erythrose, arabinose, ribose, allose, altrose, mannose, xylose, lyxose, gulose, galactose, talose, fructose, ribulose, mannoheptulose, sedoheptulose, threose, erythrito, threitol, glucopyranose, mannopyranose, talopyranose, allopyranose, altropyranose, idopyranose, gulopyranose, glucitol, mannitol, sorbitol, arabitol, xylitol, ribitol, galactitol, fucitol, iditol, inositol, pentaerythritol, dipentaerythritol, volemitol, gluconic acid, glyceric acid, xylonic acid, galactaric acid, ascorbic acid, citric acid, gluconic acid lactone, glyceric acid lactone, xylonic acid lactone, glucosamine, galactosamine, and combinations thereof.

6. A foimulation in accordance with claim 1 wherein the derivative is an esterification product of the polyol and a composition selected from the group consisting of caprylic acid, capric acid, lauric acid, mysteric acid, palmitic acid, stearic acid, arachidic acid, behenic acid, lignoceric acid, palmitoleic acid, lineolic acid, oleic acid, erucic acid, and combinations thereof.

7.

8. A formulation in accordance with claim 1 wherein the nonionic emulsifier is selected from the group consisting of fatty alcohol ethoxylates, alkylphenol ethoxylates, fatty acid ethoxylates, ethoxylated fatty esters, ethoxylated amines, fatty acid amines, terminally blocked ethoxylates, fatty acid esters of polyhydroxy compounds, fatty acid esters of sorbitol, fatty acid esters of glycerol, fatty acid esters of sucrose, alkyl polyglucosides, amine oxides, sulfoxides, phosphine oxides, and combinations thereof.

9. A formulation in accordance with claim 1 wherein the first aqueous emulsion is present in a range of from 90 weight percent to 99.95 weight percent and the second aqueous emulstion is present in a range of from 0.05 weight percent to 10 weight percent.
