Absorbent mixture and product
View Patent ↗An absorbent mixture consisting of an absorbent such as sodium or potassium polyacrylate, a fluent wax and a channeling agent. A product consisting of a porous member containing a mixture including an absorbent such as sodium or potassium polyacrylate, a fluent wax and a channeling agent.
1. A liquid water absorbing mixture comprising:
between 10 and 85 weight percent of a wax;
between about 5 and 90 weight percent of a superabsorbent selected from the group consisting of sodium polyacrylate and potassium polyacrylate; and
between about 2 and 40 weight percent of a channeling agent that conducts liquid water through the wax to the superabsorbent but does not conduct water vapor.
2. A liquid water absorbing mixture as set forth in claim 1 wherein said wax is selected from the group consisting of petroleum based, animal, vegetable and synthetic waxes.
3. A liquid water absorbing mixture as set forth in claim 2 wherein said channeling agent is selected from the group consisting of microcrystalline cellulose, gums, alginates and starches.
4. A liquid water absorbing mixture as set forth in claim 3 wherein said superabsorbent is selected from the group consisting of sodium polyacrylate and potassium polyacrylates.
5. A liquid water absorbing mixture as set forth in claim 1 wherein said channeling agent is selected from the group consisting of microcrystalline cellulose, gums, alginates and starches.
6. A liquid water absorbing mixture as set forth in claim 1 wherein the superabsorbent is encapsulated in the wax.
7. A liquid water absorbing mixture as set forth in claim 6 , wherein exposing the channeling agent to water increases the permeability of the wax.
8. A liquid water absorbing mixture as set forth in claim 6 , further including a plurality of channels defined by the wax.
9. A liquid water absorbing mixture as set forth in claim 8 , wherein at least one of the plurality of channels is formed by the channeling agent and is fluidly connected to the superabsorbent.
10. A liquid water absorbing mixture as set forth in claim 8 , wherein at least one of the plurality of channels permits liquid water to pass to the superabsorbent but prohibits the passage of water vapor to the superabsorbent.
11. A liquid water absorbing mixture as set forth in claim 8 , wherein at least one of the plurality of channels comprises a micro channel.
12. A liquid water absorbing mixture as set forth in claim 6 , wherein the channeling agent comprises microcrystalline cellulose and the wax comprises a petroleum-based wax.
13. A product comprising a porous member containing a liquid water absorbing mixture of:
between 10 and 85 weight percent of a wax;
between about 5 and 90 weight percent of a superabsorbent selected from the group consisting of sodium polyacrylate and potassium polyacrylates; and
between about 2 and 40 weight percent of a channeling agent that conducts liquid water through the wax to the superabsorbent but does not conduct water vapor.
14. A product as set forth in claim 13 wherein said wax is selected from the group consisting of petroleum-based, animal, vegetable and synthetic waxes.
15. A product as set forth in claim 14 wherein said channeling agent is selected from the group consisting of microcrystalline cellulose, gums, alginates and starches.
16. A product as set forth in claim 15 wherein said superabsorbent is selected from the group consisting of sodium polyacrylate and potassium polyacrylates.
17. A product as set forth in claim 13 wherein said channeling agent is selected from the group consisting of microcrystalline cellulose, gums, alginates and starches.
18. A product as set forth in claim 13 wherein said porous member is a string.
19. A product as set forth in claim 13 wherein said porous member is a form which has been fabricated from a sheet.
20. A product as set forth in claim 13 wherein the superabsorbent is encapsulated in the wax.
21. A liquid water absorbing mixture comprising:
between 50 and 75 weight percent of a wax;
between about 15 and 60 weight percent of a superabsorbent; and
between about 8 and 25 weight percent of a channeling agent that conducts liquid water through the wax to the superabsorbent but does not conduct water vapor.
22. A product comprising a porous member containing a liquid water absorbing mixture of:
between 50 and 75 weight percent of a wax;
between about 15 and 60 weight percent of a superabsorbent; and
between about 8 and 25 weight percent of a channeling agent that conducts liquid water through the wax to the superabsorbent but does not conduct water vapor.
23. A liquid water absorbing mixture comprising:
between 60 and 65 weight percent of a wax;
between about 21 and 25 weight percent of a superabsorbent; and
between 12 and 14 weight percent of a channeling agent that conducts liquid water through the wax to the superabsorbent but does not conduct water vapor.
24. A product
comprising a porous member containing a liquid water absorbing mixture of:
between 60 and 65 weight percent of a wax;
between about 21 and 25 weight percent of a superabsorbent; and
between about 12 and 14 weight percent of a channeling agent that conducts liquid water through the wax to the superabsorbent but does not conduct water vapor.
