に関する。Detailed Description of the Invention (Industrial Application Field) The present invention relates to improvements in various daylighting plates used as building materials, such as daylighting flat plates, curved plates, corrugated plates, folded plates, etc.
More specifically, the present invention relates to a novel infrared absorbing laminate that transmits light in the visible region but does not transmit light in the long wavelength range from the infrared region.

となり、従ってコスト高となる為、製品としては汎用性
に乏しいものであった。(Problem to be Solved by the Invention) By the way, since the above-mentioned lighting board transmits light in all visible, ultraviolet, and infrared regions, the indoor temperature rises too much in the summer, and the indoor warm air rises in the winter. This causes various problems such as escaping to the outside. Therefore, in recent years, devices have been developed and put into practical use in which a vapor-deposited film of a metal such as aluminum or silver is fixed on the surface, and the action of this vapor-deposited film reflects light in the infrared region. However,
Forming such a vapor-deposited film requires a large-scale apparatus, resulting in high costs, and the product lacks versatility.

The gist is that it is formed by depositing.

する。In addition, the above-mentioned infrared absorbing film contains S in the synthetic resin component (mainly polyvinyl chloride resin, acrylic resin, etc.) as a binder.
It is formed by applying and solidifying a paint prepared by adding nO□ fine powder, a solvent (ketone type, aromatic type, etc.), and a small amount of a dispersant (anionic surfactant, etc.) onto the above substrate. The SnO compounded in this paint has a particle size of 0.02 to 0.2μ.
S in the coating film formed on the substrate with blue fine powder of m
It is effective to set the total thickness of only nO□ to 1.5 to 20 μm, preferably 3 to 12 μm. Here, the total thickness of only SnO in the coating film is the ratio of SnO occupied in the coating film in which the coating material is entirely covered with fabric, converted into thickness. Therefore, the coating film thickness is 2.5 to 33.3 μm, preferably 5 to 20 μm, assuming that the S n O content is 60%. By the way, the total thickness is 1.5μ
If it is less than 20 μm, the effect of infrared absorption cannot be sufficiently obtained, and if it exceeds 20 μm, it tends to absorb light in the visible region as well. Particularly, those having a total thickness of 3 to 12 μm have extremely good infrared absorption function, as can be understood from the examples described later. Incidentally, the SnO fine powder may contain 5 to 20% of impurities such as antimony, and in this case, the particle size can be easily maintained in the range of 0.02 to 0.2 μm, and transparency is improved.
ここで、本発明の赤外線吸収性積層物を製造する方法の
幾つかの例を略述する。Here, some examples of methods for manufacturing the infrared absorbing laminate of the present invention will be briefly described.

Method of integrally molding in the thickness direction using hot press, (5)
The absorbent plates obtained by the methods (■) and (■) can also be used for the same purposes as described above. In this case, the hot pressing imparts shoulder ductility that fills the micro gaps between fine particles in the coating film, and the coating film after pressing is given a substantially gapless solid quality. That is, the fine particles are fixed in the coating film in a state close to so-called close packing, thereby further increasing the infrared absorption function. Therefore, (i) above
In the case of , the infrared absorbing function can be similarly increased by hot pressing afterwards.

A method in which the coating film forming sheet of (ii) above is immediately laminated onto this plate, and further formed into a waveform (including normal waves, square waves, etc.) using forming rolls. The corrugated sheets or folded sheets obtained by this method are preferably used as roofing materials for greenhouses, sunrooms, garages, and other public facilities (eg, bus stops). In this case, since the base resin plate still retains heat when the coating film-forming sheets are laminated, the same effect as the hot press described above is provided.

The materials obtained by this method are used as skylights and other unusual construction materials. In this case, due to the characteristics of compressed air or vacuum forming, the coating film is spread in the area direction, and the overall thickness of SnO is substantially reduced, so it is necessary to take this into account and increase the thickness in advance at the time of coating. There is.

。In addition to the above, a transparent acrylic resin film is laminated on top of the infrared absorbing coating to improve its weather resistance, and an ultraviolet absorber is mixed into the acrylic resin film to block the transmission of ultraviolet rays. Further, a fluororesin film such as polyvinylidene difluoride is laminated on the acrylic resin film to improve its stain resistance, etc., as appropriate. In addition, it is also possible to strengthen the base material by placing a wire mesh, glass fiber, etc. in the base material as appropriate based on the usual method.

Therefore, when this is used for daylighting purposes as described above, the rise in indoor temperature and the escape of indoor warm air are alleviated. In addition, since SnO2 itself has conductivity, the electrical resistance of the surface becomes low and antistatic properties are also imparted.

れよう。This shows that although visible light is transmitted, a considerable portion of light in the longer wavelength range than the infrared region is absorbed and its transmission is blocked.Also, the larger the total thickness of SnO It is understood that the transmittance decreases and that SnO possesses the ability to absorb infrared rays. Furthermore, the light transmittance of hot-pressed products is lower than that of non-hot-pressed products, and S
It is also understood that the effect is greater when the nO and fine particles are more densely embedded in the coating film. Although FIG. 1 shows the light transmittance of only the coating film forming sheet, this data indicates that the same infrared absorption function can be obtained for the plate formed by laminating and integrating each example sheet and the above base material. will be easily understood.

層物はその有用性極めて大である。(Effects of the Invention) As if rescued, the infrared absorbing laminate of the present invention allows visible light to pass through, but absorbs light in wavelengths longer than the infrared region, so it can be used as a daylight plate for general windows and greenhouses. Alternatively, if used as a wall material or roof material for a sunroom, etc., the temperature rise in the room can be suppressed while maintaining the lighting function. In addition, since such a function can be obtained by simply applying a paint containing fine tin oxide powder to form an adhesion, it is extremely easy to commercialize the product and can be supplied at low cost. In addition, since the tin oxide fine powder itself has conductivity, the electrical resistance of the surface is reduced, and the adhesion of dust due to static electricity is also prevented. The infrared absorbing laminate of the present invention having such remarkable characteristics is extremely useful.
