1 is a plan view showing the road-attached tape with improved visibility at night and rain in accordance with the present invention, Figure 2 is a cross-sectional view taken along the line AA 'of Figure 1, Figure 3 is a road-attached tape according to the present invention Is a view showing the shape of the arrow attached to the road by partially cutting the.

As shown, the road-attached tape with improved visibility during the rain and night according to the present invention comprises a base sheet 10, the binder layer 20, the retroreflective body 30 and the anti-slip 40.

The base sheet 10 is adhered to the road by the adhesive layer 60 of the bottom surface, a plurality of through holes 11 are formed on the top surface in a row in the horizontal direction, the vertical direction and the diagonal direction. A plurality of protrusions 13 protruding in the portion where the 11 is not formed is provided.

In addition, the through hole 11 may be formed in a long hole shape along a corresponding direction so as to be cut in a horizontal direction, a vertical direction, or a diagonal direction. Therefore, the base sheet 10 by the through hole 11, the user can be cut in any shape without the aid of a separate cutting tool to directly adhere to the arrow form as shown in Figure 3 in the field.

In addition, the through hole 11 serves as a passage through which the adhesive layer 60 of the bottom of the base sheet 10 may partially enter. That is, when the base sheet 10 is laminated on the adhesive layer 60 and the base sheet 10 is pressed, the base sheet 10 is pressed and a part of the adhesive layer 60 is inserted into the through hole 11. . Therefore, the bonding force between the base sheet 10 and the adhesive layer 60 is increased to minimize the separation of the base sheet 10 from the adhesive layer 60.

In addition, the protrusion 13 protrudes from the base sheet 10 to form an angle of 70 ~ 72 °. The protrusion angle of the protrusion 13 is formed so that the retroreflective body 30 partially embedded in the protrusion 13 protrudes vertically to reflect the headlight light of the driver at a relatively long distance, so that it can be seen by the driver. It is calculated to incline approximately 20 ° from the vertical to minimize wear or collapse by the vehicle while driving.

The binder layer 20 is applied to the side surface and the upper surface of the protrusion part 13, and includes 15 to 40 parts by weight of reflector pigment particles with respect to 100 parts by weight of the binder. The reflector pigment particles are a material that can reflect toward a light source and reflect part of incident light. Such reflector pigment particles include pearlescent pigments, mica and pearlescent pigments.

In addition, the binder may be used as one of vinyl, acrylic, epoxy, or urethane as the elastic polymer material.

The retroreflective body 30 has a refractive index of 1.9 to 2.0 and 65 to 85 wt% of the first sphere 31 having a diameter of 175 to 250 μm, and a diameter of 50 to 100 μm with a refractive index of 2.2 to 2.3. It consists of 15-35 weight% of the 2nd spheres 33 which have.

The first sphere 31 is for retroreflective in a dry state, the reflectivity is slightly reduced in the wet conditions. In addition, the second sphere 33 is for retroreflective in the wet state, the reflectivity is slightly reduced in the dry conditions. Therefore, in the present invention, by mixing the first sphere 31 and the second sphere 33 in the same ratio as described above, it is set to have even retroreflective properties in dry conditions and wet conditions.

Such spheres are preferably made of glass or non-glassy ceramics. Here, non-glassy ceramics have excellent durability and abrasion resistance, and glass may be used at a lower cost although durability is somewhat lower than that of glassy ceramics.

Therefore, the first sphere 31, which occupies a large proportion of the first sphere 31 and the second sphere 33, is made of glassy ceramic, and the second sphere 33, which occupies a small portion of gravity, is made of glass, thereby providing retroreflective properties. It can improve wear resistance and reduce costs while maintaining the cost.

The retroreflective body 30 is partially embedded in the binder layer 20 at the side surface of the protrusion part 13. Partial embedding of the retroreflective body 30 on the side surface of the protrusion 13 is to minimize the wear of the first and second spheres 31 and 33 from running of the vehicle, thereby reducing the first and second spheres 31 and 33. This is to maintain long term retroreflectivity.

The anti-slip member 40 is opaque and slip resistant and partially embedded in the binder layer 20 on the upper surface of the protrusion 13.

This anti-slip member 40 is composed of a non-glassy ceramic having a plurality of fine protrusions. Therefore, the sliding of the vehicle is prevented by the fine projection of the non-slip body 40, and made of non-glassy ceramic, it is excellent in durability and abrasion resistance, thereby exhibiting long-term anti-slip characteristics.

Meanwhile, the reinforcing net layer 50 and the adhesive layer 60 may be sequentially stacked on the bottom of the base sheet 10. The reinforcing net layer 50 is to reinforce the tensile strength of the base sheet 10, a variety of materials may be used, for example, a nonwoven fabric may be used.
