Degreasing mixture comprising a phyllosilicate/tectosilicate mixture

Abstract

The invention relates to a degreasing mixture for removing grease, oils, or similar hydrophobic components from a surface of a substrate. The degreasing mixture contains a solvent-free silicate mixture as the main component. The silicate mixture contains granules of phyllosilicate and granules of tectosilicate. Up to 90% by mass of the granules contained in the silicate mixture has a particle size of less than 60 m, and the maximum particle size of the granules of phyllosilicate is smaller than the maximum particle size of the granules of tectosilicate.

5. The degreasing mixture according to claim 1, wherein more than 50% by mass of the granules contained in the main component have a particle size greater than 20 m.

6. The degreasing mixture according to claim 1, wherein the calcium bentonite content of the main component is greater by a factor 1.1 to 2 than the tectosilicate content of the main component.

7. The degreasing mixture according to claim 1, wherein the main component contains 20 to 60% by mass of the granules of tectosilicate and 40 to 80% by mass of the granules of calcium bentonite.

8. The degreasing mixture according to claim 1, wherein the calcium bentonite is a three-layer phyllosilicate capable of swelling, and at least one component selected from the group consisting of zeolites is the main component of the granules of tectosilicate.

9. A cleaning pen for removing grease, oils, or similar hydrophobic components from a surface of a substrate, wherein the cleaning pen has a grip and an applicator containing a degreasing mixture according to claim 1.

10. A cleaning cloth for removing grease, oils, or similar hydrophobic components from a surface of a substrate, wherein the cleaning cloth has at least one layer of cloth made of a fibrous material, and the layer of cloth contains a degreasing mixture according to claim 1.

11. A tubular fiber for removing grease, oils, or similar hydrophobic components from a surface of a substrate, wherein a hollow space of the tubular fiber is at least partially filled with a degreasing mixture according to claim 1, and/or wherein an outer surface and/or an inner surface of the tubular fiber is at least partially coated with a degreasing mixture according to claim 1.

12. A degreasing mixture consisting essentially of: 0% by mass solvent; greater than 50% by mass of the degreasing mixture of a main component consisting of up to 90% by mass granules of calcium bentonite activated with sodium carbonate of a predetermined maximum particle size; and up to 10% by mass of tectosilicate granules having a predetermined maximum particle size smaller than the predetermined particle size of the calcium bentonite granules; wherein up to 90% by mass of the calcium bentonite and tectsosilicate granules have a particle size of less than 60 m.

Description

BRIEF DESCRIPTION OF THE DRAWING

(1) The invention is further described in the following with reference to a drawing that schematically shows a single embodiment. Therein:

(2) FIG. 1A shows a pen holding the degreasing mixture according to the invention for removing oils, grease, and similar hydrophobic components from textiles,

(3) FIG. 1B shows the pen according to FIG. 1A without the protective sleeve,

(4) FIG. 2 is a section through a cleaning cloth according to the invention holding the degreasing mixture according to the invention,

(5) FIG. 3 is a perspective view of a first embodiment of a tubular fiber according to the invention, and

(6) FIG. 4 is a longitudinal view of a second embodiment of a tubular fiber according to the invention.

SPECIFIC DESCRIPTION OF THE INVENTION

(7) FIGS. 1A and 1B show a cleaning pen 1 for removing oils, grease, and similar hydrophobic components from textiles. The cleaning pen 1 has a grip or handle 2 from which extends an applicator designed as a wand 3. FIG. 1A shows the cleaning pen 1 with the wand 3 is protected from damage by a protective sleeve 4. In addition to the wand 3, the protective sleeve 4 contains a mass 5 of granular degreasing mixture, so that the degreasing mixture is applied to an outer application end 6 of the wand 3.

(8) FIG. 1B shows the cleaning pen 1 with the protective sleeve 4 removed as compared to FIG. 1A. It is evident that the wand 3 is coated with the degreasing mixture 5 on the application end 6, i.e. on the outer end of the wand 3 remote from the handle 2. When the application end 6 is pressed onto an unillustrated textile, the contamination of oils and/or grease contained in the textile is taken up by the degreasing mixture 5.

(9) FIG. 2 shows a cleaning cloth 7 according to the invention that has two layers of cloth 8 and 9. A layer 10 of the degreasing mixture 5 is held between the cloth layers 8 and 9. FIG. 2 clearly shows that the cleaning cloth forms pockets 11, 12, and 13 that are separated from one another in order to prevent uncontrolled shifting of the degreasing mixture 5 in the cleaning cloth 7. When the cleaning cloth 7 is wiped over a surface not shown in FIG. 2 contaminated with grease, oils, or similar hydrophobic contaminants, the contaminants migrate into the pores of the degreasing mixture 5 [of the cloths 8 and 9] and are thereby removed from the surface.

(10) FIG. 3 shows a tubular fiber 14 whose interior 15 is partially filled with the degreasing mixture 5. According to the embodiment, a wall 16 of the tubular fiber 14 is made of a thermoplastic plastic. FIG. 4 shows a second embodiment of the tubular fiber 14. An outer surface 17 and an inner surface 18 of the tubular fiber 14 that delimits the interior 15 are both coated with the degreasing mixture 5.
