Description
【0001】[0001]
本願考案は表面に紫外線硬化(以下UVと略す)樹脂層を形成し、裏面にも樹 脂層で被覆された、接着剤による施工が容易で、耐久性があり、しかも反りの発 生しない床タイルに関する。 The invention of the present application is a floor in which an ultraviolet curing (hereinafter abbreviated as UV) resin layer is formed on the front surface and a resin layer is also coated on the back surface, which is easy to apply with an adhesive, is durable, and does not warp. Regarding tiles.
【0002】[0002]
従来より床材の表面に紫外線硬化樹脂を塗布することにより、ヒールマークが つきにくく、汚れにくくなるという利点が生じることは特公昭53−21209 号公報に示されているように一般に知られている。 It has been generally known that, by applying an ultraviolet curable resin to the surface of a flooring material, the advantages that heel marks are less likely to be attached and dirt is less likely to occur are as shown in Japanese Patent Publication No. 53-21209. .
【0003】 しかし、耐汚れ性を向上させるには紫外線硬化樹脂の架橋密度をあげる必要があ った。架橋密度を上げると、どうしても樹脂の収縮率が大きくなり、タイルが反 ってしまった。そのためUV樹脂を厚く塗布するときには、反りを防止するため にUV樹脂の架橋密度を抑制する必要があった。しかし、架橋密度が低いと床タ イルには充分な耐汚染性が得られないという問題点があった。However, in order to improve the stain resistance, it is necessary to increase the crosslink density of the ultraviolet curable resin. Increasing the crosslink density inevitably increased the resin shrinkage, causing the tile to warp. Therefore, when the UV resin is applied thickly, it is necessary to suppress the crosslinking density of the UV resin in order to prevent warpage. However, if the crosslink density is low, there is a problem in that the floor tile cannot have sufficient stain resistance.
【0004】 また架橋密度の高い耐汚染性の良い紫外線硬化樹脂は、反りを防止するために は薄くしか塗布できないので、耐久性が劣るという問題点があった。Further, an ultraviolet curable resin having a high cross-linking density and good stain resistance can be applied only thinly in order to prevent warpage, so that there is a problem of poor durability.
【0005】[0005]
本願考案はこれらの問題点を解決した床タイルで、架橋密度の高さに関係なく UV樹脂で床タイルの表面に保護層を形成するとともに床タイル裏面もUV樹脂 で被覆されることにより、反りが防止され、しかも耐汚染性および耐久性にすぐ れかつ下地との良好な接着性能を有する床タイルを提供するものである。 The present invention is a floor tile that solves these problems. A warp is formed by forming a protective layer on the surface of the floor tile with a UV resin and coating the back surface of the floor tile with a UV resin regardless of the crosslink density. The present invention provides a floor tile which is free from stains, has excellent stain resistance and durability, and has good adhesion performance to a substrate.
【0006】 本願考案は、プラスチック床タイルに紫外線硬化樹脂の表面保護層を形成した構 成において、床タイル裏面にも紫外線硬化樹脂層で被覆され、表面保護層側は比 較的厚さのある脂層であり、裏面被覆層は保護層よりも厚さが薄いことを特徴と
