The present invention relates to a base plate that can obtain high adhesive strength when attaching tile units. The present applicant previously filed an application for utility model registration as Utility Model Application No. 56-57017 regarding the design of the tile unit 6 as shown in FIG. This tile unit 6 consists of a rubberized asphalt sheet 2 with a nonwoven fabric 1 interposed in the center, a large number of tiles 3 arranged at predetermined joint intervals on one side of the sheet 2, and a large number of tiles 3 arranged at predetermined joint intervals bonded together by heating. Cotton-like heat-melting room-temperature adhesive layer 4
was applied, and a release paper 5 was pasted on the surface of this adhesive layer 4 for curing. This tile unit 6
When attaching to a structure etc., remove the release paper 5,
The surface on which the exposed adhesive layer 4 is applied is adhered to the building frame, etc., and pressing force is applied from the surface of the tile 3, thereby obtaining a construction surface that is easy to work with and ensures reliable attachment and fixation. be able to. This tile unit 6 may also be attached to a base board for application to dry construction methods. Second
The figure is an enlarged sectional view of the tile unit 6 attached to the base plate 7. Conventionally, this base plate 7 has
A regular asbestos-cement board made by kneading and molding 65% cement and 35% asbestos was used. If the base plate 7 made of a normal asbestos cement board is used as is without any treatment on the adhesion surface, the cotton-like adhesive 4 of the tile unit 6 will not fully adapt to the base plate 7.
The disadvantage was that there were scattered areas that did not adhere, resulting in a decrease in adhesive strength. In order to improve this problem, a chlorobrene-based primer has been applied to the adhesive surface of the base plate 7 to create a smooth surface that is easy to adhere to. However, the primer treatment not only requires a treatment agent such as chlorobrene, but also cannot sufficiently eliminate the unevenness existing on the adhesive surface of the base plate 7, and therefore the adhesive strength is also insufficient. Nakatsuta. The present invention was devised with the aim of solving the above-mentioned conventional drawbacks, and its gist is that 55 to 65% of Boltland cement, an appropriate amount of asbestos, A special asbestos cement board made by kneading and molding an inorganic admixture, an organic dispersant, and other additives if necessary, is finished so that the adhesive surface has a slip resistance coefficient of 0.14 or less. It is on the base plate for attaching the tile unit. First, the composition of the base plate 7 according to the present invention (hereinafter referred to as the base plate of the present invention) will be explained. Bolt land cement ensures the strength of the base plate 7, and is the most important material for forming the base plate 7 of the present invention, and in order to obtain the base plate 7 with sufficient strength, 55%
The above is necessary. However, if this exceeds 65%, unevenness tends to occur on the surface when the base plate 7 is cured. Therefore, the amount of Boltland cement is
The range was 55-65%. Asbestos is an important material for the base plate 7 to maintain its shape as a plate material and maintain its toughness. A suitable amount for this is 15-25%. The inorganic admixture prevents unevenness from forming on the surface of the base plate 7 when it is cured. Its suitable addition amount is 5 to 10%. In the embodiment of the present invention, asbestos tailings were used as the inorganic admixture. The organic dispersant has the effect of uniformly dispersing the local aggregation of Bortland cement particles, asbestos, and inorganic admixture fibers, and makes the strength and toughness of the base plate 7 uniform throughout. It not only prevents the surface from becoming rough, but also prevents the surface from becoming uneven. A suitable addition amount for this purpose is 10-12%. In the examples of the present invention, pulp was used as the organic dispersant. In the present invention, if necessary, it is also possible to add a very small amount of coloring agent. In order to adhere the tile unit 6 to the base plate 7 of the present invention with sufficient adhesive strength, it is necessary to finish the surface of the base plate 7 so that the surface condition to which it is adhered is appropriate. The surface condition of the base plate 7 in this case must have a slip resistance of 0.14 or less as measured by the test method (pendulum type) specified in JIS A1407. In the embodiment of the invention, the surface finish was by buffing and polishing. However, the polishing means is not limited. Next, a comparison test between the base plate of the present invention and a conventional base plate will be explained. Table 1 shows the manufacturing conditions of the base plate, and Table 2 shows the adhesive strength in air, water, and hot water. In addition, the adhesive layer of the tile unit has
The main material is synthetic rubber such as styrene-butadiene rubber, butyl rubber, and styrene-isobutylene block polymer, with addition of natural resins such as low-polymerized polyisobutylene and logi, terpene-modified, aromatic petroleum resins, etc. as tackifiers. , which was applied in a linear manner.

cm 2 or more, which is significantly superior to conventional products, and the adhesive strength in water and hot water is also superior to conventional products. In this test example, the adhesive layer was provided linearly, but it goes without saying that the adhesive layer may be provided over the entire surface of the adhesive layer. The effects of the present invention are due to the fact that the adhesive surface of the base plate made of a special asbestos cement board was polished and smoothed, and the degree of smoothness was measured using a surface roughness meter. A chart in that case is shown in FIG. A in the same figure is a conventional base plate with primer treatment applied to the adhesive surface, and B in the same figure is
1 shows the bonding surface of a conventional base plate polished by buffing, and C in the same figure shows the surface roughness of the base plate of the present invention. As can be seen from these figures, the conventional base plate has a rough surface regardless of whether it is subjected to primer treatment or polishing treatment. In particular, even though both the conventional one and the inventive one were finished by buffing as shown in Figures B and C, the conventional one still has a rough surface, while the inventive one still has a rough surface. It has a smooth surface, and a characteristic difference can be seen in this point. This difference is due to the fact that the conventional base plate is made of ordinary cement and asbestos, and because the amount of cement is large, the material has a rough structure, and no matter how much polishing it is done, a smooth surface cannot be obtained. be. As described above, the present invention applies a polishing treatment to a special asbestos cement board to create a base board with an adhesion surface with a slip resistance coefficient of 0.14 or less, thereby making it possible to reliably and firmly adhere the tile unit attached to this base board. It is something that can be done.
