Invention patent for a shoe sole rubber paint composition, characterized by comprising a mixture of 35-48% PVC resin, 30-40% dioctyl terephthalate DOTP-based plasticizer, 1-3% calcium/zinc tris (nonylphenyl) phosphite stabilizer, 15-30% nitric rubber powder and 1-4% non-toxic organic pigment, a process for manufacturing shoe soles using said composition and a shoe sole product resulting from said process.

Claims

1. “SHOE SOLES” manufactured in a rubberized ink wherein the composition comprises a preferential mixture of: 35 to 48% of PVC resin; 30 to 40% of dioctyl terephthalate (DOP)-base plasticizer; 1 to 3% of a tris nonylphenyl phosphite Calcium/Zinc stabilizer; 15 to 30% of nitrile rubber powder; and 1 to 4% of nontoxic organic pigment.

2. “PROCESS” for manufacturing of shoe soles, according to claim 1, wherein it comprises: the steps of engraving of drawings, logo and text on a nylon netting of 40 to 45 wires (1); the cut and preparation of the substrates of neoplex or neoprene rubberized fabric (2) preferably of 3 mm, leaving them with a printing area for one or more soles pairs; the dilution of the rubberized ink with (3) the dioctyl terephthalate (DOTP)-based softener, in the order of 2 to 4% of the ink mixture to be used; the silk screen (4) of a first layer of ink on the substrate; where after the step of printing of the drawings of the sole on the substrate (5) it is made the drying for formation of relieves (6), which is made by thermal blower or flashcure for ten seconds at every coating; being repeated the process of printing and drying (7) for four or more sections until reaching a preferential height; after this phase, the substrates with the layers of printed drawings go to drying in oven (8), where they are cured or polymerized for three minutes at a temperature of 180°; and finally they are cut out in the form of the sole (9), and available for the composition of shoes, preferably slippers manufactured with the same rubberized fabric.

3. “PRODUCT RESULTING FROM SHOE SOLE”, according to claims 1 and 2, wherein it comprises a product resulting from a sole (9) in neoplex or neoprene rubberized fabric, with drawings, text and logos in an anti-skid relief (10).

[0031] The FIG. 08 represents an upper view of the printed substrate, going through a flashcure heater or oven.

[0032] The FIG. 09 represents a view in perspective of a sole with its rubberized relieves, cut out and ready to compose the shoe sole, which can be made by gluing, welding or sewing, or a combination among them.

DETAILED DESCRIPTION OF THE FIGURES

[0033] As it is evident in the attached figures which illustrate and are part of this descriptive report of the invention at issue of “Composition, Process and Product Resulting from Shoe Soles”, it is the composition of a rubberized ink, comprised of a preferential mixture of: 35 to 48% of PVC resin; 30 to 40% of dioctyl terephthalate (DOTP)-base plasticizer; 1 to 3% of a tris nonylphenyl phosphite Calcium/Zinc stabilizer; 15 to 30% of nitrile rubber powder; and 1 to 4% of nontoxic organic pigment.

[0034] The plasticizer of the composition can be replaced in the same proportion, by dioctyl phthalate DOP, also known as bis (2-ethylhexyl) phthalate.

[0035] In FIGS. 01, 02, 03, 04, 05, 06, 07 and 08 in annex are presented the steps of the process, which is started with engraving of drawings, logo and text on a nylon netting of 40 to 45 wires (1); the cut and preparation of the substrates of neoplex or neoprene rubberized fabric (2), preferably 3 mm, leaving them with a printing area for one or more soles pairs; the dilution of the rubberized ink with (3) the dioctyl terephthalate (DOTP)-based softener, in the order of 2 to 4% of the ink mixture to be used; the silk screen (4) of a first layer of ink on the substrate; where after the step of printing of the drawings of the sole on the substrate (5) it is made the drying for formation of relieves (6), which is made by thermal blower or flashcure for ten seconds at every coating; being repeated the process of printing and drying (7) for four or more sections until reaching a preferential height; after this phase, the substrates with the layers of printed drawings go to drying in oven (8), where they are cured or polymerized for three minutes at a temperature of 180°; and finally they are cut out the form of the sole (9), and available for the composition of shoes, preferably slippers manufactured with the same rubberized fabric.

[0036] In FIG. 09 in annex it is demonstrated the sole (9) in neoplex or neoprene rubberized fabric, with drawings, text and logos in an anti-skid relief (10).

[0037] Through this process and with simple changes it is possible the formation of divers settings of drawings and/or logos in relieves in soles; application of individual colors or set of colors, which make the sole more attractive; being ideal to compose the sole of a high variety of shoes, preferably slippers manufactured in the same material.

[0038] The sole (9) with drawings in relief (10), described and presented here, are not Limited to these disposals, settings, and measures, once the same preponderant characteristics are kept.
