ものである。However, in these conventional techniques, the strength of fixing of the aggregate is small, so that the aggregate may fall off, and especially roads under severe conditions such as friction, impact, and cold and hot. In the case of a covering material or the like, the purpose cannot be sufficiently achieved. In addition, in the method described in JP-A-3-100204, in addition to the above-mentioned problem, a long time is required for curing because a radical polymerizable composition is used as a matrix resin. This involves the problem that the time required is long and the construction is affected by the weather, and the size of the molded product is also limited. The present invention has been made in view of the above-mentioned circumstances, and has a surface with a high adhesion strength of an aggregate, and further has excellent abrasion resistance, heat resistance, and contamination resistance, and is suitable for outdoor use such as a guideway, and its inexpensive and easy-to-use sheet. It is intended to provide a manufacturing method.

Has a function of preventing the peeling and falling off of the aggregate by filling the gap between the aggregates (3) and (3) and exerting a non-slip effect by the aggregate. It is desirable to partially compensate for a height of about 2/3 to 3/4. If the degree of make-up is too small, the exfoliation of the aggregate is likely to occur, and if the degree of make-up is too large, the non-slip effect is reduced. Further, in order to effectively prevent the exfoliation and detachment of the aggregate by the matrix resin layer (4), it is necessary that the adhesive strength between the aggregate (3) and the adhesive layer (2) is high. It is preferable that such a matrix resin has a composition similar to that of the adhesive layer, but on the other hand, the viscosity of the matrix resin is set to a low value because of the properties of the matrix resin, which require permeability to the aggregate gap. Is preferred.

In order to further increase the adhesive strength, a silane coupling agent and a titanium coupling agent are preferred. It is preferable to add one or two or more of an isocyanate-based polymer, an acrylic resin, an epoxy-based resin, and the like. Further, since the matrix resin is applied from above on the aggregate by spraying or the like, the generation of air bubbles due to the entrainment of air is expected. Therefore, a sol composition having good defoaming properties and natural foaming properties is preferred. The matrix resin may be a transparent sol, but may be a colored sol in consideration of fashion. The matrix resin layer (4) is formed by a spray, a sponge roll, a curtain flow coater or the like on the aggregate (3) temporarily fixed by the adhesive layer (2).

Preferably, as shown in FIG. 2, a surface coating layer (5) is further provided on the surface of the uneven surface sheet. The surface coating layer (5) improves the surface performance of the uneven surface sheet, such as surface strength, heat resistance, abrasion resistance, and stain resistance, and is made of acrylic, urethane, epoxy, etc.
A heat or ultraviolet curable resin composed of a combination of two or more species is preferably used, but for the purpose of improving abrasion resistance, heat resistance, and stain resistance, the surface coating layer is formed by crosslinking vinyl chloride paste sol. It can also be formed. Also,
In the formation of the surface coating layer (5), it is necessary to prevent the aggregate from being exposed and the non-slip effect on the surface from being reduced, and for this purpose, the coating method of the coating material is important. That is, a spray, a curtain flow coater, a sponge roll, or the like is suitable as a method for applying the surface coating without burying the aggregate (3).

To 100 parts by weight of this resin solution, 2 parts by weight of Cadox B-CH50 (manufactured by Kayaku Nury Co., Ltd.) was added as a radical polymerization catalyst, dissolved, and coated on the sheet by a roller. The curing time of this resin solution was 1 hour or more, and the workability was extremely poor. Further, since the resin solution was coated on the aggregate, the non-slip effect was extremely poor.
