Industrial Application Fields The present invention relates to laminates, and more specifically, the present invention relates to laminates, in particular, laminates formed by forming a coating layer with novel surface properties on various base materials such as metal, plastic, wood, fiber, rubber, and paper. Regarding the body. BACKGROUND ART Conventionally, various types of coatings have been applied to various base materials for corrosion protection, decoration, and other improvements in surface properties. Particularly in recent years, differentiated coatings have attracted attention, and attempts have been made to impart unique functions to the surface of base materials, creating a fashion-like appearance that appeals to the senses,
That is, there is a demand for a surface treatment that imparts design functions such as an appearance and texture that are significantly different from the appearance of the base material itself. Problems to be solved by the invention Examples of the above-mentioned design functions include providing a dry and smooth appearance or a textured and elegant appearance, and a soft feeling that blends in with moisturized skin. Examples include adding a texture. However, in the prior art, even if each of these functions can be provided independently, it has not been known to satisfy a plurality of functions at the same time, that is, to provide a composite function. An object of the present invention is to provide a laminate having a surface layer that has the above-mentioned complex functions that have not been previously available. Means for Solving the Problems The laminate of the present invention consists of a base material made of metal, plastic, wood, fiber, rubber, or paper, and a coating layer containing a filler formed on the surface of the base material,
The surface of the coating layer has a pitch of 0.1 to 50 μm, preferably 0.5 to 30 μm, particularly preferably 1.0 to 15 μm, and a depth of
It has irregularities of 0.1 to 25 μm, preferably 0.5 to 15 μm,
And 60 degree light reflectance is 0.1~50%, preferably 0.2~
20%, surface dynamic friction coefficient 0.15-0.50, preferably
It is characterized by being 0.2 to 0.4. The surface properties of the coating layer specified in the present invention express the texture and appearance of the surface having the design function aimed at by the present invention, and are expressed by the following mechanical measurement values. The pitch and depth are the average values of the values measured by observing the length and depth of the pitches of the convex and convex portions of the unevenness formed on the surface of the coating layer using an electron microscope photograph. The 60 degree light reflectance is measured according to the direction of JIS Z8741, and is the acceptance rate of the reflected light, which is expressed in % when light is applied to the surface of the coating layer at an incident angle of 60 degrees. The surface dynamic coefficient of friction is calculated by applying a vertical load of 500 g to a test piece (dimensions 100 mm x 200 mm) using a surface property tester, and moving the specimen 100 mm/min at a moving speed of 50 mm/min. The average frictional resistance is divided by the vertical load. It is calculated by the value. In the present invention, the pitch and depth of the unevenness on the surface of the coating layer are factors that affect the texture and appearance.
If the pitch is less than 0.1 μm, the texture will be less slippery and the appearance will be less dry, while if it exceeds 50 μm, the softness of the texture will be impaired and the appearance will be rough, which is undesirable. Moreover, if the depth is less than 0.1 μm, the soft feel will be impaired, while if it exceeds 25 μm, the slipperiness will increase, which is not preferable. The 60-degree light reflectance is an element that affects the appearance, especially the texture, and if the reflectance exceeds 50%, the texture will become faded, which is not desirable. Furthermore, the coefficient of surface dynamic friction is a factor that is involved in the dampness of the texture, and if this coefficient is less than 0.15, the dampness will become weaker, while if it exceeds 0.50, the stickiness will increase, which is undesirable. Effect The laminate of the present invention has a surface of the filler-containing coating layer formed on the base material as described above, which has irregularities with a pitch of 0.1 to 50 μm and a depth of 0.1 to 25 μm,
In addition, since the 60 degree light reflectance is 0.1 to 50% and the surface dynamic friction coefficient is 0.15 to 0.50, the light projected onto the surface is diffusely reflected depending on the pitch and depth of the surface unevenness, giving it a unique appearance. Become. Furthermore, when the surface of the coating layer is touched with a finger, the contact area with the finger is reduced, so it has a unique tactile texture. Examples Examples of the present invention will be described below. FIG. 1 shows an embodiment of the present invention, in which 1 is a base material and 2 is a coating layer. The coating layer has a resin matrix 3 and a filler 4 dispersed therein. FIG. 2 shows another embodiment of the present invention, in which a primer layer 5 is formed on the base material 1. Base materials that can be used in this invention include various metals such as iron, copper, aluminum, magnesium, and titanium, ABS resin polystyrene, polycarbonate,
Examples include various plastics such as acrylic resin, synthetic or natural wood, fiber, leather, rubber, or paper. Suitable coating materials for forming the coating layer include compositions in which various thermoplastic resins are blended with rubber compounds, various fillers, and optionally crosslinking agents.When coated with this composition, the surface properties of the coating layer The blending ratio is determined so as to have the following properties. Furthermore, in the present invention, the covering layer may have an intermediate layer. Providing a soft synthetic resin in the intermediate layer is preferable because it gives a softer feel to the laminate. Suitable examples of such synthetic resin include soft polyvinyl chloride and soft polyurethane. Next, more specific examples of the laminate of the present invention will be shown. Example 1 After cleaning the surface of the ABS resin plate according to the usual method,
A coating agent containing 100 parts by weight of polyurethane resin, 10 parts by weight of nitrile rubber, 20 parts by weight of fine silica powder with a secondary particle size of 0.5 μm, and 10 parts by weight of isocyanate prepolymer as film-forming components was spray-painted, and then heated at 60°C. Heat and dry for 20 minutes with
A laminate with a coating film of 18 μm was obtained. The surface roughness, 60 degree light reflectance, and surface dynamic friction coefficient of the obtained laminate were measured, and the results are shown in Table 1. This laminate exhibited unique surface properties: it had a moist and soft feel, while its appearance was dry and smooth, and had an excellent texture. Examples 2 to 4 A laminate was obtained by carrying out the same method as in Example 1 except that the particle size of the fine silica powder used as the coating agent was changed as shown in Table 1.
The surface characteristics, appearance, and texture of each of the obtained laminates were as shown in Table 1. Examples 5 to 8 In the method of Example 1, the base material was replaced with an ABS resin plate, and polystyrene plates, polypropylene plates,
A laminate was obtained by carrying out the same method except for using an iron plate, an aluminum plate, and synthetic leather. The surface characteristics of each of the obtained laminates were similar to those of Example 1, with a unique texture and appearance. In addition, as a base material, polyolefin primer (product name: EURAK) is used for the polypropylene plate.
C-2575A (manufactured by Hirono Chemical Industry Co., Ltd.), and halogenated rubber primer (product name: U-PLY) for the iron plate.
P-1107 (manufactured by Hirono Kagaku Kogyo Co., Ltd.) was coated, and then the above coating was applied. Examples 9 and 10 A laminate was obtained by carrying out the same method as in Example 1 except that the composition of the coating agent was partially changed as shown in Table 1. The surface characteristics, appearance, and texture of each of the obtained laminates were as shown in Table 1. Example 11 In the method of Example 1, 150 μm of polyurethane urea resin (trade name: Hanitatsu HP-915KS, manufactured by Hirono Chemical Industry Co., Ltd.) was coated on an ABS resin plate in advance.
A laminate was obtained by carrying out the same method except that a coating film was formed as an intermediate layer and a coating agent was spray-painted thereon. The resulting laminate has a texture with elasticity,
The laminate of Example 1 exhibited a surface texture with a softer feel. Comparative Examples 1 to 3 Laminates were obtained by carrying out the same method as in Example 1 except that the coating agent composition was changed to that shown in Table 1. The surface characteristics, appearance, and texture of each of the obtained laminates are as shown in Table 1, and no unique surface properties were obtained as in the laminates obtained in Examples.
