Abstract

A method for formulating a composition contains the step of coating a granular absorbent material with a coating agent to produce a coated absorbent material and mixing the coated absorbent material with a sanitation agent, wherein the coated absorbent material absorbs the sanitation agent to form the liquid loading composition. Liquid-loading compositions that can absorb liquids in many applications, including clean-up and farming, are also disclosed.

Claims

1. A method of formulating a composition, comprising the steps of:

coating a granular absorbent material with a coating agent to produce a coated absorbent material; and

mixing the coated absorbent material with an absorbable agent,

wherein the coated absorbent material absorbs the absorbable agent to form the composition.

2. The method of claim 1, wherein the absorbable agent is a liquid.

3. The method of claim 1, wherein the granular absorbent material is coated with a layer of surface bonded biocide by vapor deposition, pressure micro droplet spray or fuming or fogging nozzle.

4. The method of claim 1, wherein the granular absorbent material is selected from the group consisting of ceramic minerals, zeolite, activated carbon, fumed silica, processed clays, cellulosic absorbents, fibrous absorbents and combinations thereof.

5. The method of claim 4, wherein the granular absorbent material comprises ceramic minerals.

6. The method of claim 5, wherein the ceramic minerals comprise perlite and/or vermiculite.

7. The method of claim 1, wherein the coating agent is a biocide.

8. The method of claim 7, wherein the biocide is selected from the group consisting of silanes, siloxanes, aminopropyltrimethoxysilane, quaternary amines, fumed metal hydroxides, solutions of silver, solutions of copper and combinations thereof.

9. The method of claim 1, wherein the coating agent forms a surface bonded film on the granular absorbent material.

10. The method of claim 1, further comprising the step of:

grinding an absorbent material to produce the granular absorbent material used in the coating step.

11. The method of claim 1, wherein the absorbable agent is selected from the group consisting of chlorine bleach solutions, hydrogen peroxide solution, per acetic acid, quaternary amine solutions, alcohol solutions and combinations thereof.

12. The method of claim 1, wherein the composition is capable of absorbing liquid at a liquid loading of 25-30% by volume or 200-300% by mass addition.

13. The method of claim 1, further comprising the step of:

adding a modifying agent to the composition in an amount sufficient to achieve desired physical characteristics for the composition.

14. The method of claim 13, wherein the modifying agent comprises a thickening agent, a gum, an absorbent polymer or combinations thereof.

15. The method of claim 13, wherein the modifying agent comprises a carboxymethyl cellulose (CMC)-derived polymer and/or a hierarchically porous carbons (HPC)-derived polymer.

16. A liquid loading composition, comprising:

a granular absorbent material coated with a biocide; and

an absorbable agent absorbed in said granular absorbent material.

17. The liquid loading composition of claim 16, wherein the granular absorbent material is selected from the group consisting of ceramic minerals, zeolite, activated carbon, fumed silica, processed clays, cellulosic absorbents, fibrous absorbents and combinations thereof.

18. The liquid loading composition of claim 16, wherein the granular absorbent material comprises ceramic minerals.

21. The liquid loading composition of claim 20, wherein the biocide forms a surface bonded film on the granular absorbent material.

22. The liquid loading composition of claim 16, wherein the absorbale agent is selected from the group consisting of chlorine bleach solutions, hydrogen peroxide solution, per acetic acid, quaternary amine solutions, alcohol solutions, periodine and combinations thereof.

23. The liquid loading composition of claim 16, wherein the liquid loading composition is capable of absorbing liquid at a liquid loading of 25-30% by volume or 200-300% by mass addition.

24. The liquid loading composition of claim 16, further comprising:

a thickening agent, a gum, an absorbent polymer or combinations thereof.

25. The liquid loading composition of claim 16, further comprising a carboxymethyl cellulose (CMC)-derived polymer and/or a hierarchically porous carbons (HPC)-derived polymer.

26. A method of making a liquid loading composition, comprising the steps of:

coating a high surface area solid with a non-toxic bio static film.
