The present invention will be described in more detail based on the accompanying preferred embodiments as follows.

Referring to FIG. 1 , in the present invention, a base base material surface treatment process (S1) is performed as a first process. The present invention is practiced and the base base material 10 shown in FIG. 2 may be a metal plate and a plastic plate such as a stainless plate, a steel plate, or an aluminum plate, and preferably has a thickness of 1 to 2 mm and is press-cut or cut to have an elongated plate shape. that will be used

Therefore, when the base base material 10 is a stainless steel plate or a steel plate, the surface of the base base material 10 is sandblasted by spraying sand or metal grains onto the base base material 10, or brushed with a brush, followed by acid treatment. surface treatment to be performed. The acid treatment is acid treatment using weak sulfuric acid or ferric chloride, and the acid treatment time is to be immersed or coated at room temperature for 30 to 40 minutes to surface-treat, and after acid treatment, it is allowed to dry naturally at room temperature for 24 hours. This allows the acid component, which is a volatile component, to disappear naturally or is washed.

Therefore, in the present invention, when the surface of the base base material 10 is sandblasted or brushed with a brush in the base surface treatment process, the surface of the base base material 10 becomes rough, so that the liquid molding resin composition ( 30) is to increase the bonding force coupled to the surface of the base material 10, and the acid treatment serves to clean the surface of the base material 10.

And when the base base material 10 is an aluminum plate material, it is surface treated by anodizing in chromic acid solution. As such, the above-described anodizing treatment technology and primer treatment technology are already known, so a detailed description thereof will be omitted.

Therefore, in the present invention, the base base material surface treatment process (S1), which is a first process of roughening in order to increase the bonding force of the liquid molding resin composition 30 on the surface of the base base material 10 as described above, is performed. At this time, the roughness for generating the uneven surface on the surface of the base material 10 is preferably about 50 microns.

Next, in the present invention, the pretreatment composition manufacturing process (S2) is carried out as a second process. The pretreatment composition manufacturing process (S2) is, 1 to 16wt% of benzyl alcohol, 20 to 23wt% of bisphenol A diglycidyl ether, 5 to 7wt% of methyl isobutyl ketone, 31 to 32wt% of limestone, talc powder 4~5wt%, glycidoxypropyltrimethoxysilane 3~4wt%, hydrophobic silicon dioxide 3-4wt%, ihip body fatty acid base epoxy resin solution 12~14wt%, alkyl glycidyl ether 4~5wt%, color ink By mixing and mixing 2-5 wt% in a mixer, the liquid resin composition of the main material is prepared, and the material properties of the compositions are already known in the art, so detailed descriptions will be omitted.

At this time, the color ink is selectively mixed with color ink such as yellow ink or red ink so that the color non-slip protrusion 30 ′ shown in FIG. 4 has visibility. Therefore, it can be said that the second process, the pretreatment composition manufacturing process (S2), is a pretreatment process in which the color ink is mixed to obtain the main material liquid resin composition having a color.

Next, as a third process, the molding resin composition manufacturing process (S3) is performed. This process is a manufacturing process in which 20 to 33 wt% of the main material liquid resin composition obtained in the second process, 62 to 72 wt% of abrasive grains, and 5 to 8 wt% of the curing agent are mixed in a mixer to obtain the liquid molding resin composition (30). At this time, it is preferable to rotate and stir at 2000 to 3000 rpm together with the ceramic ball in the mixer so that each component is uniformly and well mixed.

The abrasive grain is preferably a ceramic material powder such as tungsten carbide, alumina or zirconia, silicon carbide, which is a wear-resistant material, and the size of the powdered abrasive grains 32 and 32' is preferably 60 to 80 mesh size, and a curing agent A room temperature curing agent such as an amine polyamide is preferable.

Next, in the present invention, a color non-slip molding process (S4) is performed as a fourth process. As shown in FIG. 2, the above process is mounted and fixed so that the molding die 20 having the molding hole 21 on the surface of the base material 10 is in close contact, and then the liquid molding resin composition 30 is used with the molding hole 21. ) is a process that allows input. The depth of the forming hole 21 is preferably about 1 to 2 mm.

The molding die 20 is preferably made of silicone rubber, and the molding hole 21 may be, for example, a simple straight shape, or a butterfly shape, or may be processed into a specific pattern shape such as a letter or an arrow. , the color non-slip protrusion 30 ′ protruding from the surface of the base base material 10 of the finally completed non-slip member protrudes in the same shape as the shape of the forming hole 21 described above.

And to insert the liquid molding resin composition 30 into the molding hole 21, the roller (not shown) on which the liquid molding resin composition 30 is embedded is pushed to the upper surface of the molding die 21 to form the molding hole 21 . It is preferable to input the liquid molding resin composition 30 by a screen printing method to be filled.

On the other hand, in order to help the understanding of the present invention, the liquid molding resin composition 30 is largely divided into liquid resin 31 and abrasive grains 32 to be described.

Therefore, when the color non-slip molding process (S4) of the fourth process is completed, the liquid molding resin composition 30 in the molding hole 21 is the liquid resin 31 and the abrasive grain 31 as shown in FIG. 3 (a). ) is in a mixed state as a whole, and in this state, the present invention performs the abrasive gravity drop process (S5) of the fifth process.

In the abrasive grain gravity dropping process (S5), as shown in (a) of FIG. 3 , the liquid resin 31 and the abrasive grains 31 are left as they are for 10 to 15 minutes in a mixed state as a whole, and relatively more than the liquid resin 31 . It is a process in which the abrasive grains 32 having a high specific gravity fall downward by gravity so that the abrasive grains 32 are accumulated toward the base base material 10 as shown in FIG. 3(b).

Next, in the present invention, the additional abrasive dispersion application process (S6) of the sixth process is carried out. This process is a process of dispersing and applying the abrasive grains 32' on the upper part of the liquid molding resin composition 30 as shown in FIG. 4 (a) before the liquid resin 31 is temporarily cured.

That is, the liquid resin 31 included in the liquid molding resin composition 30 in the molding hole 21 is temporarily cured after 20 to 30 minutes have elapsed. Therefore, the abrasive grains 32 mixed with the liquid resin 31 fall by gravity within 10 to 15 minutes and the abrasive grains 32 are accumulated toward the upper side of the base material 10, and in this state, the liquid resin 31 is It is to be applied by dispersing the abrasive grains 32 ′ on the upper part of the liquid molding resin composition 30 before being heated.

Therefore, since the abrasive grains 32' that are dispersed and additionally applied to the upper portion of the liquid molding resin composition 30 are before the liquid resin 31 is temporarily hardened, some abrasive grains 32' are gradually dropped in the downward direction by gravity. As a result, it is in a state in which it is dispersedly immersed in the liquid resin 31 above the abrasive grain 32, which has fallen to the lower side, as shown in Fig. 4 (b). As the provisional curing of (31) proceeds, the additionally applied abrasive grains (32') no longer fall, so that the abrasive grains (32') at the top are in a state of protruding from the upper part of the liquid resin (31) and have slip resistance. will be.

In order to help the understanding of the present invention, by mixing more the content of the abrasive grains 32 in the molding resin composition manufacturing process (S3) of the third process mentioned above, the specific gravity is relatively high before the liquid resin 31 is temporarily cured. Even if the high abrasive grains 32 fall by gravity, it may be exposed to the upper surface of the liquid resin 31, but in this case, the abrasive grains 32 that fall downward by gravity before the liquid resin 31 is temporarily hardened. Since the abrasive grains 32 are exposed to the upper surface of the liquid resin 31 only when other abrasive grains 32 are continuously piled up upward, the content of the solid abrasive grains 32 is relatively higher than that of the liquid resin 31 having fluidity. There was a phenomenon in which the viscosity of the liquid molding resin composition 30 was considerably increased because there were too many.

Therefore, since the viscosity of the liquid molding resin composition 30 is considerably excessively increased, screen printing is not properly realized when performing the color non-slip molding process (S4) of the fourth process. (21) is not sufficiently filled or the screen printing speed is relatively slow, resulting in a significant decrease in productivity, as well as waste of abrasive grains (32), which are relatively expensive than liquid resin (31), and increase in cost. phenomenon has occurred.

However, as in the present invention, by performing the abrasive grain gravity drop process (S5) of the fifth process and the abrasive grain additional dispersion application process (S6) of the sixth process, screen printing is improved and the waste of the abrasive grains 32 is prevented in advance. By exposing the abrasive grains 32' to the upper surface of the liquid resin 31, it is possible to have slip resistance.

Next, in the present invention, the mold detachment and curing process (S7) of the seventh process is carried out, and this process is 100 to 120 minutes from the time the liquid resin 31 is temporarily cured, and the base base material ( 10) Detach and remove the mold 20 from the mold and then dry it naturally at room temperature for at least 24 hours so that the liquid resin 31 is completely cured, or force the resin to dry at 60 to 100 ° C for 12 to 15 hours in a drying room. As shown in (b) of FIG. 4, (31) is to be a fully cured solid resin 31'.

Therefore, the present invention provides a non-slip member for anti-slip visibility having a color non-slip protrusion 30 ′ in a solid state in which the liquid molding resin composition 30 is completely cured on the surface of the base material 10 when the seventh process is completed. will get

Therefore, the non-slip member of the present invention is surface-treated to form an uneven surface on the surface of the base base material 10, so that the attachment area of the color non-slip protrusion 30' is expanded, as well as the abrasive grains 32 that have fallen into the grooves of the uneven surface first. Since the liquid resin 31 is hardened in a fitted state, durability and resistance to external force are greatly improved. In order to help the understanding of the present invention, for example, when a large walking force acts on the color non-slip protrusion 30 ' in a state protruding from the surface of the base base material 10, or when an external force to be kicked is applied to the base base material 10, Since a large number of abrasive grains 32 are dropped to the surface and are accumulated, they have external force resistance because many abrasive grains 32 are caught in the grooves, so that the color non-slip protrusion 30 ' from the base base material 10 does not fall easily. it will have durability.

In addition, in the present invention, even if the upper part of the color non-slip protrusion 30 ' is worn over a long period of use, numerous abrasive grains 32 are dropped to the surface of the base base material 10 and are accumulated on the lower side of the color non-slip protrusion 30 ' Since the sliding resistance is not lowered and the original role can be faithfully performed, even if the color non-slip protrusion 30' is worn, the sliding resistance is not lost at all, and at the same time, the abrasive grains 32 and 32' made of ceramic particles. ), the abrasion resistance is superior and the slip resistance is not lost at all, so it is possible to further secure the safety against slip accidents.

And the present invention uses the color non-slip protrusion 30' having visibility as shown in FIG. Therefore, it is possible to add logos, safety phrases, and guides, so that the usability of the product is greatly improved and the reliability of the product can be greatly improved.

The present invention is not necessarily limited to what has been shown and described in the drawings, and since it may be modified in various forms by those of ordinary skill in the art to which the present invention pertains, it is obvious that it should be broadly protected as long as it does not significantly depart from the scope of the claims. did it
