  The present invention has been made in view of the above-described background art, and an object of the present invention is to provide a highly safe anti-slip material in which silica sand is buried in a paint portion so that particles are hardly peeled off.

  The present invention is a slope device that is used as a transfer plate or a slope provided with a non-slip portion on the running side surface or the step side surface of the tread member, wherein the anti-slip portion is provided on the surface side of the tread member. The structure is characterized in that a silica sand part is buried inside the urethane part.

  In the present invention, since the silica sand of the silica sand part is buried inside the urethane part, the silica sand does not protrude from the coating film constituting the urethane part, and the particles are not easily peeled off and can provide a high safety slip. . In the present invention, if the tread member is made of aluminum and a two-component ultrafast curing urethane paint is used for the urethane part, the urethane part can be attached to the tread board member. Further, in the present invention, when the tread member is composed of a plurality of tread base materials and is formed in a continuous pattern over the entire surface of the plurality of tread base materials, the anti-slip portion is viewed from above. In such a case, the tread member is blindfolded by the anti-slip portion so that the boundary between the plurality of tread base members constituting the tread member is not visible, and a sense of security can be given to the person using the tread member.

  The directions of “front”, “rear”, “left”, “right”, “upper” and “lower” in this specification are viewed from the front side indicated by the arrow 101 with the slope device 11 placed in the state of FIG. The direction specified in the case.

  With reference to FIG. 1, the anti-slip | skid part 2 provided in the surface as a driving | running | working side surface or a step side surface of the tread member 1 which concerns on the form 1 for implementing invention is demonstrated. The non-slip part 2 includes a primer part 3 provided on the surface of the tread member 1, a first urethane part 4 provided on the primer part 3, and a silica sand part 5 provided on the first urethane part 4. The second urethane portion 6 provided on the silica sand portion 5 and the top coat portion 7 provided on the second urethane portion 6. That is, the anti-slip portion 2 has a structure in which the silica sand portion 5 is disposed between the first urethane portion 4 on the surface side of the tread member 1 and the second urethane portion 6 on the upper side of the first urethane portion 4. In other words, the non-slip portion 2 has the silica sand portion 5 inside the urethane portion composed of the first urethane portion 4 on the surface side of the tread member 1 and the second urethane portion 6 above the first urethane portion 4. It is a buried structure. Since the urethane resin is used for the first urethane part 4 and the second urethane part 6 that bury the silica sand part 5 in this way, it is excellent in wear resistance and tear resistance as compared with resins other than the urethane resin. Therefore, the anti-slip portion 2 has high durability and is excellent in elasticity, so that it has a high anti-slip effect and is easy to form a thick film. Further, since the silica sand part 5 is buried in the urethane resin composed of the first urethane part 4 and the second urethane part 6, the silica sand part 5 is difficult to peel off.

  With reference to FIG. 2, the construction procedure of the anti-slip | skid part 2 which concerns on the form 1 for implementing invention is demonstrated. In step 101, for example, a two-component mixed epoxy-modified polyurethane is applied to the entire surface of the tread member 1 as a primer to form the primer portion 3. Since the two-component mixed epoxy-modified polyurethane is used as the primer, when the tread member 1 is aluminum, the tread member 1 is better attached to the tread member 1 than the one-component modified epoxy paint. When the tread member 1 is FRP, a one-component modified epoxy paint may be used. In step 102, after the epoxy-modified polyurethane of the primer portion 3 is cured, a two-component super-fast curing urethane coating is applied to the entire upper surface of the primer portion 3 as urethane, for example, to form the first urethane portion 4. In step 103, for example, silica sand having a particle diameter of 0.1 to 2.5 mm is applied to the entire upper surface of the first urethane portion 4 before the two-component ultrafast curing urethane coating of the first urethane portion 4 is cured. Be sprayed. As a result, the silica sand is captured by the two-component ultrafast curing urethane coating of the first urethane portion 4. By selecting a silica sand having a particle diameter of 0.1 to 2.5 mm, it is possible to exhibit anti-slip and durability. On the other hand, when the particle size of the silica sand is smaller than the above range, the anti-slip property is inferior. When the particle size of the silica sand is too larger than the above range, shoes etc. are easily caught.

  In step 104, after the dispersion of the silica sand and the curing of the two-component ultrafast curing urethane coating of the first urethane portion 4, the two-component ultrafast curing urethane coating is applied to the entire upper surface of the silica sand portion 5 as urethane, for example. The second urethane portion 6 is formed. As a result, the two-component ultrafast curing urethane coating reaches the upper surface of the first urethane portion 4 from between the silica sand while covering the silica sand of the silica sand portion 5, and the upper surface of the first urethane portion 4 from between the portion covering the silica sand and the silica sand. The upper surface of the second urethane portion 6 becomes uneven based on the portion that has reached. In step 105, after the two-component ultrafast curing urethane paint of the second urethane part 6 is cured, a urethane-based paint is applied as a top coat to the entire upper surface of the second urethane part 6 to form the top coat part 7 Form. Thereby, the construction procedure of the anti-slip | skid part 2 is complete | finished. By selecting the thickness of the coating film of the first urethane part 4 and the second urethane part 6 to be 0.3 to 0.5, it is possible to exhibit anti-slip and durability. On the other hand, if the thickness of the coating film of the first urethane part 4 and the second urethane part 6 is too thin than the above range, silica sand can be easily removed, and the thickness of the coating film of the first urethane part 4 and the second urethane part 6 However, if the thickness is too thick, the edge of the silica sand will be lessened and slip resistance will be poor.

  In the construction of the non-slip portion 2 according to the embodiment 1 for carrying out the invention, since the ultrafast curing urethane paint is used, the silica sand portion 5 is placed inside the urethane resin composed of the first urethane portion 4 and the second urethane portion 6.
