Stabilized solutions of alkylalkoxysilane hydrolysates and flexible films formed thereof
A stabilized mixture containing an alkyltrialkoxysilane hydrolysate solution and an amine functional silicone emulsion is provided. The stabilized mixture may be utilized in a masonry treatment product or a cellulosic or wood treatment product, such as to provide waterproofing properties, or in a hair care treatment product for improving hair combability. A method of preparing the mixture involves hydrolyzing an alkoxysilane to form an aqueous solution containing alkylsilanetriols and/or oligomeric alkylsilanetriol condensates; and stabilizing the solution by adding an amine functional silicone.
1. A stabilized mixture comprising an alkyltrialkoxysilane hydrolysate solution, an amine functional silicone emulsion, and a polyalkylsiloxane fluid,
wherein the solution comprises alkylsilane triols and low molecular weight condensation products thereof having two to three silicon atoms.
2. The mixture according to claim 1 , wherein the alkyl group in the alkyltrialkoxysilane contains about one to ten carbon atoms.
3. The mixture according to claim 2 , wherein the alkyl group contains about two to eight carbon atoms.
4. The mixture according to claim 1 , wherein the alkoxy group in the alkyltrialkoxysilane contains about one to four carbon atoms.
5. The mixture according to claim 1 , wherein the silicone emulsion contains a high molecular weight amine functional polysiloxane containing alkoxy groups.
6. The mixture according to claim 1 , wherein the polyalkylsiloxane is selected from polymethylethylsiloxane and polydiethylsiloxane.
7. The mixture according to claim 1 , wherein the amine comprises an aminopropyl or aminoethylaminopropyl substitution.
8. A method of preparing the mixture according to claim 1 , comprising hydrolyzing an alkoxysilane to form an aqueous solution comprising alkylsilanetriols and/or oligomeric alkylsilanetriol condensates; and stabilizing the solution by adding an amine functional silicone.
9. The method according to claim 8 , wherein byproduct alcohols are optionally removed from the solution.
10. The mixture according to claim 1 , further comprising a silanol-terminated diphenyl siloxane-dimethylsiloxane copolymer.
11. The mixture according to claim 1 , wherein the mixture contains phenethylsilanetriol.
12. The mixture according to claim 1 , wherein the mixture contains at least two different silanetriols.
13. A masonry treatment product comprising the stabilized mixture according to claim 1 .
14. A cellulosic or wood treatment product comprising the mixture according to claim 1 .
15. A hair care treatment product comprising the mixture according to claim 1 .
16. A method of waterproofing a masonry object comprising applying the mixture according to claim 1 to the object.
17. A method of waterproofing a cellulosic or wood object comprising applying the mixture according to claim 1 to the object.
18. A method of improving sensory characteristics of hair comprising applying the mixture according to claim 1 to the hair, wherein the sensory characteristics include at least one of shine, feel, and combability.
