BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a vertical sectional front view of a durable coloring body, and FIG. 2 is a perspective view. The durable coloring body (1) has a white hard undercoat layer (3) formed on the surface of a substrate (2). On the surface of the hard undercoat layer (3), a coloring layer (4) is formed by transfer. On its upper surface, a transparent side chain reaction double bond type acrylic resin layer (5) having a hardness of about 5H is formed.
[0010]
The material of the base material (2) may be any material as long as it is plate-shaped and has a certain degree of hardness (to the extent that the tip does not hang down when held horizontally). The substrate shown in the figure is a base material obtained by impregnating a mixed resin (a soft candy resin obtained by kneading necessary materials for FRP) with a mineral fiber cloth (woven cloth, mat) such as glass or carbon, and hardening it into a belt shape. 2) is used. The plate thickness is, for example, about 0.8 mm.
[0011]
The compounded resin is a soft syrup-like material obtained by adding a curing agent and other necessary materials to, for example, a thermosetting resin (for example, an unsaturated polyester resin) as a base resin and kneading the mixture. Cured by reaction heat or external heating).
[0012]
The surface of the base material (2) is subjected to a pretreatment such as degreasing and surface roughening (omitted if not necessary) to form a hard undercoat layer (3) on the surface. The hard undercoat layer (3) improves the coloring property and the adhesiveness of the coloring layer (4), and prevents the upper side chain reaction double bond type acrylic resin layer (5) from cracking. The hardness is preferably closer to the hardness (5H) of the side-chain reaction double bond type acrylic resin layer (5), and is a hard resin having a hardness of 3H to 5H (for example, a high molecular urethane acrylate resin or a polyfunctional urethane acrylate resin). A paint is used in which a white material (for example, gofun, lime, clay, lead white, etc.) is kneaded, but a transparent material is also used.
[0013]
After the hard undercoat layer (3) is cured, the transfer paper is applied to the upper surface thereof, and by pressing the iron from above, the thermocompression bonding is performed to transfer the coloring layer of the transfer paper to the undercoat layer (3). . Thereby, the coloring layer (4) is in close contact with the hard undercoat layer (3). In this case, a side-chain reaction double bond type acrylic resin layer (5) is formed on the hard undercoat layer (3), cured by irradiating an electron beam, and then a coloring layer (4 ) Can be formed.
[0014]
From the top of the coloring layer (4) to the hard undercoat layer (3), a side-chain reaction double bond type acrylic resin layer (5) is formed by coating in the range of 80 μm to 120 μm. And irradiating the side-chain reaction double bond type acrylic resin layer (5) with an electron beam for about 0.5 seconds in a nitrogen atmosphere (oxygen concentration: 500 ppm or less) under a pressurized voltage of 300 keV and an acceleration current of 65 mA. Thereby, the side chain reaction double bond type acrylic resin layer (5) is cured.
[0015]
In forming the side-chain reaction double bond type acrylic resin layer (5), the resin is made to have fluidity by a solvent, and spray coating can be applied uniformly. Although the layer thickness may be thick, there is no need for a further layer thickness in terms of abrasion resistance due to cross-linking unevenness due to electron beam transmission unevenness, and abrasion resistance problems occur if it is too thin. For example, the above range of 80 to 120 microns, preferably around 100 microns is sufficient. After the formation of the layer, drying by heating at 130 ° C. for 1 minute to 1.5 minutes or drying under reduced pressure in a reduced pressure chamber is performed.
[0016]
The hardness of the side chain reaction double bond type acrylic resin layer (5) is about 5H and is harder than the ultraviolet curable resin, so the coloring layer (4) coated on the side chain reaction double bond type acrylic resin layer (5) is It is not damaged by stepping on shoes, does not burn when burned by cigarettes, and is water resistant even when immersed in water. Further, even if the colored layer (4) is exposed to sunlight for many years, it does not transmit ultraviolet rays, so that the coloring layer (4) does not fade.
[0017]
When the core of the base material (2) is, for example, a woven tape of a mineral fiber such as carbon fiber, a hard undercoat layer (3) is directly formed on the surface, and a coloring layer (4) by hand-drawing or the like is formed on the upper surface. Can be formed. In this case, light emission at night or in a dark place can be obtained by using a phosphorescent paint or the like for the coloring layer (4). In addition, the pigment is kneaded in the side-chain reaction double bond type acrylic resin, and directly applied to the upper surface of the base material (2), whereby the coloring layer (4) and the side-chain reaction double bond as the protective layer are it can be formed type acrylic resins layer (5) at the same time.
[0018]
The colored layer (4) shown in FIG. 2 is a horizontal stripe of red and yellow, and the belt-shaped durable colored body (1) is used for, for example, a step portion of a road surface, an obstacle at a construction site, a road surface used for road guidance, and the like. It is configured as a marking strip. The cured side-chain reaction double bond type acrylic resin layer (5) is hard, so it is hard to be damaged even if it is continuously stepped on by shoes, etc., and it has excellent durability without discoloration even if exposed to sunlight for many years. ing.
[0019]
When the phosphorescent paint is used for the coloring layer (4), it can be easily recognized even in a dim place. In this case, abrasive grains (eg, sand, corundum, carborundum, glass, etc.) are sprayed under the side-chain reaction double bond type acrylic resin layer (5), and the side-chain reaction double bond type acrylic resin layer is dispersed. When fixed in (5), the shoe is supported by the abrasive grains even when stepping on the shoe, so that the abrasion resistance is improved.
