Anti-icing coatings and methods
View Patent ↗A method of inhibiting or preventing bonding between snow or ice and a substrate is provided. The method includes applying an adhesive to the substrate, broadcasting an aggregate onto the adhesive to form an aggregate-adhesive and applying an anti-icing chemical onto the aggregate-adhesive.
1. A method of inhibiting or preventing bonding between snow or ice and a substrate, the method comprising:
applying an adhesive to the substrate;
broadcasting an aggregate onto the adhesive to form an aggregate-adhesive;
applying an anti-icing chemical onto the aggregate-adhesive.
2. The method of claim 1 , wherein the adhesive comprises at least one of an epoxy, styrene, methyl-methacrylate, tar and a combination thereof.
3. The method of claim 1 , wherein the adhesive comprises at least one of an epoxy and a tar.
4. The method of claim 1 , wherein the substrate comprises pavement.
5. The method of claim 1 , wherein the substrate includes at least one of a road, a bridge, an airport runway, tarmac and a surface on which a vehicle may travel.
6. The method of claim 1 , wherein the aggregate comprises at least one of flint, silica sand, basalt, free dirt, clay, limestone, dolomite slag, and combinations thereof.
7. The method of claim 1 , wherein the aggregate comprises limestone.
8. The method of claim 1 , wherein the aggregate comprises dolomite.
9. The method of claim 1 , wherein the anti-icing chemical comprises at least one of calcium magnesium acetate, potassium acetate, sodium acetate, sodium chloride, sodium formate, magnesium chloride, propylene glycol, propylene glycol with urea additive, ethylene glycol with urea additive, potassium carbonate, and combinations thereof.
10. The method of claim 1 , wherein the aggregate is broadcast in such a manner that portions of the aggregate are not encompassed by the adhesive so that the anti-icing chemical can fill pores of the aggregate.
11. The method of claim 1 , further comprising curing the adhesive.
12. The method of claim 1 , further comprising applying a second adhesive and broadcasting a second aggregate, the second adhesive and second aggregate being the same as or different from the adhesive and aggregate.
13. The method of claim 1 , further comprising cleaning the aggregate-adhesive to enhance residual effect of the aggregate-adhesive.
14. The method of claim 1 , wherein the method induces a residual effect.
15. The method of claim 1 , wherein broadcasting further comprises at least one of sprinkling, dropping and spraying aggregate over the adhesive.
16. An anti-icing composition comprising:
an adhesive and an aggregate, at least a portion of the aggregate being encompassed by the adhesive and having a plurality of pores; and
an anti-icing chemical at least partially filling one of the pores, and wherein the adhesive comprises at least one of an epoxy, styrene, methyl-methacrylate, tar and a combination thereof.
17. The composition of claim 16 , wherein the adhesive is secured to a substrate.
18. The composition of claim 17 , wherein the substrate comprises pavement.
19. The composition of claim 17 , wherein the substrate includes at least one of a road, a bridge, an airport runway, tarmac, and a surface on which a vehicle may travel.
20. The composition of claim 16 , wherein the adhesive comprises at least one of an epoxy and tar.
21. The composition of claim 16 , wherein at least a portion of the aggregate is not encompassed by the adhesive.
22. The composition of claim 16 , wherein the anti-icing chemical comprises at least one of calcium magnesium acetate, potassium acetate, sodium acetate, sodium chloride, sodium formate, magnesium chloride, propylene glycol, propylene glycol with urea additive, ethylene glycol with urea additive, potassium carbonate, and combinations thereof.
23. The composition of claim 16 , wherein the aggregate comprises at least one of flint, silica sand, basalt, free dirt, clay, limestone, dolomite, slag, and combinations thereof.
24. An anti-icing composition comprising:
an adhesive and an aggregate, at least a portion of the aggregate being encompassed by the adhesive and having a plurality of pores; and
an anti-icing chemical at least partially filling one of the pores, and wherein the adhesive comprises at least one of flint, silica sand, basalt, free dirt, clay, limestone, dolomite, slag, and combinations thereof.
25. The composition of claim 24 , wherein the aggregate comprises limestone.
26. The composition of claim 24 , wherein the aggregate comprises dolomite.
27. The composition of claim 24 , wherein the anti-icing chemical comprises at least one of calcium magnesium acetate, potassium acetate, sodium acetate, sodium chloride, sodium formate, magnesium chloride, propylene glycol, propylene glycol with urea additive, ethylene glycol with urea additive, potassium carbonate, and combinations thereof.
28. The composition of claim 24 , wherein the composition exhibits a residual effect.
29. The composition of 24 , wherein at least a portion of the aggregate is not encompassed by the adhesive.
30. An anti-icing composition comprising
an adhesive at least partially encompassing at least one of limestone and dolomite having pores; and
an anti-icing chemical at least partially filling at least one pore of the limestone and the dolomite.
31. The composition of claim 30 , wherein the adhesive is secured to a substrate.
32. The composition of claim 31 , wherein the substrate comprises pavement.
33. The composition of claim 31 , wherein the substrate includes at least one of a road, a bridge, an airport runway, tarmac, and a surface on which a vehicle may travel.
34. The composition of claim 30 , wherein the adhesive comprises at least one of an epoxy, styrene, methyl-methacrylate, tar and a combination thereof.
35. The composition of claim 30 , wherein the adhesive comprises at least one of an epoxy and a tar.
36. The composition of claim 30 , wherein the anti-icing chemical comprises at least one of calcium magnesium acetate, potassium acetate, sodium acetate, sodium chloride, sodium formate, magnesium chloride, propylene glycol, propylene glycol with urea additive, ethylene glycol with urea additive, potassium carbonate, and combinations thereof.
