BACKGROUND OF THE INVENTION Conventionally, flexible sheets made of a fibrous base fabric with a soft vinyl chloride resin (hereinafter referred to as PVC) layer formed on one or both sides have been used in large tents such as air domes. This material has the essential advantages of PVC in terms of processability, economy, flame resistance, etc. However, since such tents are exposed outdoors for long periods of time, they do not contain enough stabilizers, etc. Even though it has been carefully examined, the resin gradually decomposes over many years, and the plasticizer migrates to the surface and gradually becomes sticky, and furthermore, there are serious drawbacks such as dust adhering to the top surface and contamination. It had

合もあり、不満足なものであつた。 As a countermeasure to these shortcomings, an attempt was made to form an acrylic resin film layer on the top surface of the PVC layer, thereby covering up the shortcomings of conventional laminate products with only a PVC layer, and this countermeasure has been quite effective. I'm giving. However, even in this case, depending on the usage conditions of the laminate, cracks may occur in the acrylic resin film layer under conditions such as being rubbed strongly, which can further spread and damage the underlying PVC layer, significantly reducing the service life of the laminate. In some cases, the result was shortened, which was unsatisfactory.

れることが好ましい。 Next, in the laminate of the present invention, an acrylic resin film layer is formed with a non-uniform thickness on at least the upper surface of the PVC resin coating layer on the front side. The acrylic resin film layer provides weather resistance and antifouling properties to the laminated product, and in particular suppresses the bleeding of the plasticizer contained in the PVC resin coating layer, and also prevents the generation of surface decomposition products of the layer and the surface resistance due to the bleed. It is known to be effective in preventing adhesion. This acrylic resin film layer is selected from films produced by the T-die method, the inflation method, or other methods, and both stretched and unstretched films can be used, but they have a low degree of molecular orientation. It is preferable to use unstretched or lightly stretched material. Usually, the thickness of the acrylic resin film layer is 1

にあるという点に存する。 A feature of the laminate product of the present invention in which the acrylic resin film layer as described above is formed on the top surface is that the thickness of this acrylic resin film layer is uneven, and the surface thereof has many fine irregularities. When a part of the area of 3 square mm (1.73 mm square) or more is sampled from any location and measured, the thickness is 20 mm.
The point is that the ratio of the total area of the ~50 μm portion to the total area of the 20-1 μm thick portion is in the range of 80-20 to 20-80.

Press with a forming plate or roll having uneven depth. Alternatively, both sides of a film having a uniform thickness may be pressed with a forming plate or roll having a large number of fine irregularities. In this case, the thickness of each part of the film layer is measured by cutting the film at right angles to the surface of the film to be measured.

ために好ましい。 In the prior art, as shown in FIG. 1, the entire surface of the acrylic resin film layer 3 is constructed to be smooth. However, the laminate of the present invention is characterized in that the acrylic resin film layer 4 is formed with a non-uniform thickness as shown in the figure, and has many fine irregularities on its surface. Something,
In particular, if a part with an area of 3 mm2 or more is taken from any part of the area, the total area of the part with a thickness of 20 to 50 μm and the total area of the part with a thickness of 20 to 1 μm are
It is configured to have a ratio of 80-20 to 20-80. The formation of the PVC resin coating layer 2' on the back side may be omitted, or an acrylic resin film layer having a non-uniform thickness similar to that on the front side may be provided on the back PVC resin coating layer 2'. In the laminate product of the present invention, an acrylic resin film that has been pre-formed to a non-uniform thickness and has many fine irregularities is coated with a PVC resin coating layer 2,
Alternatively, a smooth acrylic resin film is pasted on the surface of the PVC resin coating layer, and then the film is pressed to a predetermined thickness. It is also possible to form a large number of fine irregularities due to non-uniformity. However, it should be noted that this pressing process does not create irregularities on the surface merely for the sake of an aesthetic glossy appearance or pattern. In the laminate product of the present invention, variation in thickness is specified in a certain area, that is, in an area of 3 mm2 or more, but this is limited to a relatively thick part with a thickness of 20 to 50 μm.
This is because it has been experimentally confirmed that when the area ratio with the relatively thin portion of 20 to 1 μm is formed in the above-mentioned ratio, the most excellent effect can be achieved in preventing cracks in the film. The difference in thickness between the two parts is preferably at least 3 μm, preferably 5 μm or more. If the ratio is out of the range specified above, the thickness of the entire film becomes almost uniform even though it may be thick or thin, and the object of the present invention cannot be fully achieved. Further, in FIG. 2 according to the present invention, PVC
Although the case where the surface of the resin coating layer is relatively smooth is shown, the surface of the PVC resin coating layer may have irregularities as shown in FIG. 3. Also,
It is preferable that the lower surface portion of the PVC resin coating layer penetrates and bites into the inside of the base fabric in order to increase the adhesive strength between the two.

In addition, in the shape of the uneven part, the diameter of the protruding part or the diagonal length (D), the diameter of the recessed part,
Alternatively, it is also possible to define the relationship D/W with the length (W) of the diagonal line, but the point is that in the acrylic resin film layer that forms the surface of the actual laminate product, as mentioned above, the part with a thickness of 20 to 50 μm It is sufficient that the ratio of the total (integral) area of the area to the total (integral) area of the 20 to 1 μm thick portion is 80 to 20 to 20 to 80. The shape of the unevenness is not particularly limited, but it is preferable that the unevenness be uniformly distributed. In addition, it is empirically known that favorable results can be obtained when forming unevenness by preheating the acrylic resin film to a temperature range of glass transition point (Tg) +30℃ to melting point (Tm) -10℃. , may be carried out under other conditions. In shaping, both the film and the shaping tool may be heated simultaneously or separately.

The laminate product of the present invention has the above-mentioned structure, and the PVC resin coating layer is covered with an acrylic resin film layer to promote its weather resistance, and to prevent aging caused on the surface of the product and plasticizer bleed. It can prevent the occurrence of stickiness and exhibit stain resistance. In addition, conventional acrylic resin film layers had the disadvantage that they easily cracked under harsh usage conditions, such as intense rubbing conditions, which significantly reduced their service life. By using an acrylic resin film layer with minute irregularities, the phenomenon of cracking completely disappears, and therefore the underlying PVC layer does not crack either, maintaining an extremely good condition for many years. be able to. For this reason,
The laminated product of the present invention can exhibit remarkable effects when applied to outdoor equipment such as tents, vehicle tops, and outdoor storage canopies, which are used under conditions such as flapping due to strong winds. Furthermore, in the laminate product of the present invention, due to the presence of the acrylic resin film layer,
Welding is possible. The laminate of the present invention having the above characteristics is extremely useful in practice.
