2. Description of the Related Art As a conventional ultraviolet / infrared ray blocking material which can be applied to a transparent window glass for buildings and vehicles and can block both ultraviolet rays and infrared rays, as described in JP-A-2-75683, ZnO powder. and an inorganic ultraviolet absorber such as and TiO ₂ powder, UV-that both the inorganic infrared absorbing agent such as MgO powder or SiO ₂ powder formed by spraying the material containing the polymer resin solution on a glass surface There is an infrared blocking film.

Further, the zinc oxide thin film which is an ultraviolet absorbing film and 1 to 20 atom% with respect to zinc atoms which is an infrared absorbing film.
An ultraviolet / infrared ray blocking material obtained by stacking a zinc oxide thin film containing Al on a transparent substrate such as a window glass by a sputtering method, a vacuum deposition method, a CVD method or the like is disclosed in JP-B-4-4472.
It is described in Publication No. 1.

[0005]

However, Japanese Patent Laid-Open No. 2-75
The ultraviolet / infrared blocking film described in Japanese Patent No. 683 does not have a sufficient blocking effect particularly in the near infrared region, so that the solar radiation transmittance (JIS
R 3106) cannot be made sufficiently low, and as a result, the effect on air conditioning (cooling effect and heat retaining effect) is impaired. Further, since two kinds of fine powders having different characteristics such as specific gravity are used, insufficient mixing may cause uneven performance of the film.

On the other hand, a method of laminating an ultraviolet blocking film and an infrared blocking film as described in Japanese Patent Publication No. 4-44721 is
The process is complicated and the cost is high. Further, with the recent increase in the size of buildings and vehicles, the window glass tends to have a large area, but there is a drawback that it is difficult to cope with the large area by film formation by sputtering, vacuum deposition, CVD or the like.

In view of the above-mentioned problems of the prior art, an object of the present invention is to use one type of powder having both an ultraviolet ray blocking action and an infrared ray blocking action at the same time to make it easy and large in area for coating or molding. It is an object of the present invention to provide an ultraviolet / infrared ray blocking material having an excellent blocking action against ultraviolet rays and infrared rays, particularly near infrared rays, by only one layer formed by an easy method.

[0008]

Means for Solving the Problems As a result of repeated research aimed at achieving the above-mentioned objects, the present inventors have found that zinc oxide powder known to exhibit excellent ultraviolet absorbing ability contains a small amount of a specific dope metal. The present invention has been completed based on the finding that when contained, it exhibits infrared reflectivity, particularly near infrared reflectivity, without substantially impairing its ultraviolet absorbing ability.

The present invention relates to Si, Ti, V, Cr, Mn, Fe, Co,
One or two or more metals selected from the group consisting of Ga, Ge, Zr, In, Sn, and Hf are added in a total amount of 0.1 to
A characteristic is that zinc oxide powder (hereinafter, simply referred to as zinc oxide powder) contained at a ratio of 25 atomic% is used as a powder for blocking ultraviolet rays / infrared rays or infrared rays in combination with a resin. The film obtained by the present invention is superior in ultraviolet blocking performance to a metal-doped zinc oxide film formed by a sputtering method or the like.

Specifically, the constitution of the present invention is as follows.
Is. In the solvent, characterized by containing the zinc oxide powder, and an organic resin soluble or dispersible in the solvent,
Ultraviolet / infrared blocking film forming material.

An ultraviolet / infrared ray blocking film formed from the above ultraviolet / infrared ray blocking film forming material.

An infrared ray blocking film forming material, characterized in that the solvent contains the zinc oxide powder and an organic resin soluble or dispersible in the solvent.

An infrared blocking film formed from the above infrared blocking film forming material.

A molding material for an ultraviolet / infrared shielding material, characterized in that the zinc oxide powder is dispersed in a molten or softened organic resin.

A film or molded product formed from the above molding material and having a function of blocking ultraviolet rays and infrared rays.

A molding material for infrared ray blocking material, characterized in that the above zinc oxide powder is dispersed in a molten or softened organic resin.

A film or molded body having an infrared ray blocking function, which is formed from the above molding material.

An ultraviolet / infrared ray blocking film, an infrared ray blocking film, a film having an ultraviolet ray / infrared ray blocking function, or a film having an infrared ray blocking function described in the above item 1 or 2 is provided on at least one side of glass. , Transparent windows for construction and vehicles.

The zinc oxide powder used in the present invention is made of Si, Ti,
Contains one or more metals of V, Cr, Mn, Fe, Co, Ga, Ge, Zr, In, Sn, and Hf (hereinafter, these metals may be referred to as doped metals) as oxides However, the balance is zinc oxide powder consisting essentially of zinc oxide. This powder exhibits an infrared ray blocking action in addition to the excellent ultraviolet ray blocking action exhibited by zinc oxide, and exhibits a remarkably excellent infrared ray blocking effect not seen in conventional materials, particularly in the near infrared region.

The zinc oxide powder doped with such another metal is converted to zinc hydroxide by adding an alkali to an aqueous solution containing zinc chloride and chloride of the doped metal to hydrolyze the chloride. It can be produced by an appropriate known method such as coprecipitation with a hydroxide of a doped metal and firing the coprecipitate to form an oxide.

Preferred doped metals are V, Cr,
Mn, Co, Ga and Hf. The content of the doped metal (when two or more kinds of doped metals are contained, the total amount) is 0.1 to 25 atom% based on the total amount of metal (that is, the total amount with zinc).
However, preferably 1 to 15 atom%, more preferably 1
~ 10 atom%. If the content of the doped metal is less than 0.1 atomic%, it is impossible to secure the infrared ray blocking effect, particularly the near infrared ray blocking effect. On the other hand, if the content of the dope metal exceeds 25 atomic%, the powder has a strong color tone depending on the dope metal, coloring the blocking material, and the effect is saturated and no further improvement of the infrared blocking effect is observed. .

The average particle size of the zinc oxide powder used in the present invention is not particularly limited, but it is required to have transparency such as when it is formed on a transparent substrate such as glass or when it is used as a transparent molded article. At 0.5 μm or less, especially 0.1 μm
It is preferably m or less. However, if transparency is not required so much, zinc oxide powder having a larger particle size, such as an average particle size of 1 μm or more, can be used.

In the present invention, (a) the above zinc oxide powder is made into a paint by using an organic resin as a binder, and the obtained film forming material is applied onto a suitable substrate to be used as an ultraviolet / infrared ray blocking film. Alternatively, (b) it is kneaded into an organic resin to obtain a molding material, which is molded into a film or a molded body, which is used as a film or a molded body having an ultraviolet / infrared ray blocking function. As the zinc oxide powder, two or more zinc oxide powders having different doped metal species and / or the content of the doped metal may be used.

This ultraviolet / infrared shielding film, and a film and a molded product having an ultraviolet / infrared shielding function (in the present invention, these are collectively referred to as an ultraviolet / infrared shielding material).
In addition to being used for blocking ultraviolet rays and infrared rays, since the zinc oxide powder has an excellent infrared ray blocking effect, particularly a near infrared ray blocking effect, it can also be used only for infrared blocking purposes. Below, in order to simplify the explanation,
Infrared ray blocking materials will be explained, but when used as infrared ray blocking materials (that is, infrared ray blocking films and films and molded products having an infrared ray blocking function), the composition and preparation method of the film forming material and molding material, and further the film forming The means and molding means may be the same as the ultraviolet / infrared ray blocking material.

The type of organic resin is not particularly limited, and both thermoplastic resins and thermosetting resins can be used, but it is preferable to select from organic resins having excellent transparency. As for the organic resin, two or more kinds of resin mixtures may be used as long as they are compatible with each other. The organic resin can be appropriately selected by those skilled in the art according to the usage pattern and field of use of the ultraviolet / infrared blocking film or blocking material.

For example, in the case of a coating type ultraviolet / infrared ray blocking film forming material in which an organic resin is contained in a solvent together with zinc oxide powder, an organic resin generally used for a transparent coating (clear lacquer) can be used. . It goes without saying that it is necessary to use an organic resin that is soluble or dispersible in the solvent used.

Organic resins suitable for use in paint type film forming materials include acrylic resins, epoxy resins, polyester resins, polyurethane resins, polycarbonate resins, water-soluble alkyd resins, polyvinyl alcohol, polybutyl alcohol, and acrylic resins. , Acrylic-styrene, or vinyl acetate-based emulsion type water-dispersible resin.

The solvent used for the paint-type film forming material is selected from those capable of dissolving or dispersing the organic resin depending on the organic resin used. Examples of suitable solvents include:
Water; monohydric or polyhydric alcohols such as methanol, ethanol, butanol, ethylene glycol; benzene,
Aromatic hydrocarbons such as toluene and xylene; Alicyclic hydrocarbons such as cyclohexane; Aliphatic hydrocarbons such as hexane and octane; Diacetone alcohol, diethylene glycol, butyl carbitol, isophorone, acetone, methyl ethyl ketone, methyl Ethers, ketones, and esters such as isobutyl ketone, cyclohexanone, and ethyl acetate; halogenated hydrocarbons such as dichloromethane and carbon tetrachloride; and two or more functional groups such as dimethylformamide, butylcarbitol acetate, and diethanolamine Examples thereof include a solvent containing a group. A mixed solvent composed of two or more kinds of solvents can also be used as long as they are compatible with each other.

On the other hand, in the case of a kneading-type molding material for ultraviolet / infrared ray blocking material in which zinc oxide powder is kneaded and dispersed in a molten or softened organic resin, it is used for producing a transparent film or a transparent molding. A resin selected from the organic resins that have been used can be used in the present invention. Suitable resins include acrylic resin, polycarbonate resin, polyester resin, polyvinyl chloride resin, polyvinylidene chloride resin, polypropylene resin, polystyrene resin, AB
S resin etc. are mentioned. The resin used is not limited to such general-purpose resins, and various functional resins such as heat resistant resins and weather resistant resins can also be used. For example, use of a heat resistant resin is preferable in applications where the substrate is exposed to high heat.

In the case of a paint type ultraviolet / infrared ray blocking film forming material, the organic resin (amount as solid content) is mixed in an amount of 10 to 900 parts by weight, particularly 25 to 500 parts by weight, based on 100 parts by weight of zinc oxide powder. Preferably. The solvent may be in an amount such that a viscosity suitable for the film forming means used is obtained,
Usually, it is in the range of 100 to 5000 parts by weight with respect to 100 parts by weight of zinc oxide powder.

If necessary, the film forming material may contain a proper amount of a curing agent, a crosslinking agent, a curing accelerator, a catalyst and the like. Further, a small amount of one or more additives commonly used in paints, such as pH adjusting agents, defoaming agents, lubricants, wetting agents, leveling agents, etc., may be added.

The ultraviolet / infrared ray blocking film forming material of the present invention is
It can be produced by mixing and dispersing the above components in the same manner as in the preparation of paint. By applying this film-forming material to a substrate such as glass or transparent plastic by a means such as dipping, coating, printing or spraying, the solvent is heated if necessary to remove the solvent, and then dried (crosslinking and curing in some cases). The ultraviolet / infrared ray blocking film of the present invention is formed. The drying temperature may be selected according to the type of solvent or organic resin.

The thickness of the ultraviolet / infrared ray blocking film of the present invention is not particularly limited, but 0.1 to 10 μm is required in order to sufficiently exert the ultraviolet ray / infrared ray blocking action and to secure appropriate transparency.
A thickness of about m is suitable, and preferably in the range of 0.1 to 5 μm.

If desired, an overcoat layer made of a transparent hard metal oxide such as silicon oxide or zirconium oxide is formed on the ultraviolet / infrared shielding film by, for example, a usual sol-gel method to a thickness of 0.1 to 1 μm. You may provide with a thin film. As a result, the ultraviolet / infrared ray blocking film is less likely to be scratched and durability is greatly improved.

In the case of a window glass for buildings or vehicles, it can be used as a laminated glass in which the ultraviolet / infrared ray blocking film of the present invention is sandwiched between two sheets of glass. This laminated glass is obtained by blocking glass that has the ultraviolet / infrared ray blocking film of the present invention formed on one side and ordinary glass, or two sheets of glass having the ultraviolet ray / infrared ray blocking film of the present invention formed on one side. It can be manufactured by putting a film inside and sticking it by fusion of a transparent adhesive or resin.

In the case of a kneading type molding material for ultraviolet / infrared ray blocking material, the compounding amount of the organic resin (amount as solid content) is 50 to 50,000 parts by weight, especially 100 parts by weight of zinc oxide powder. A range of 100 to 5000 parts by weight is preferable. The compounding may be carried out by any method capable of uniformly dispersing the powder in the molten or softened resin. For example, a method of kneading zinc oxide powder into an organic resin softened using a kneading roll, a method of mixing using an appropriate melt mixer such as an extruder or a kneader, and the like are possible. A conventional additive such as a dispersant, a plasticizer, a coupling agent, a wetting agent, a lubricant, etc. may be added to the molding material in a small amount. When the resin is thermosetting, a curing agent and a crosslinking agent are added as needed.

The molding material of the present invention is molded into a film or a molded body by a conventional method. Molding methods include blown film molding, extrusion molding, injection molding, compression molding,
Press molding, blow molding, etc. can be adopted, but other molding methods are also possible. Thus, a film or molded product having an ultraviolet / infrared ray blocking function (eg, sheet, panel, fiber, tube, three-dimensional molded product, etc.) is obtained.

In the case of a film, a thickness of 50 to 500 μm is suitable. This film can be imparted with an ultraviolet / infrared ray-blocking function by adhering it to a window glass or other substrate requiring ultraviolet / infrared ray blocking with a transparent adhesive. Sheets, panels, pipes, and three-dimensional molded products are used as they are as products with UV / IR blocking function. By mixing this with other fibers as the case may be, a fiber product can be produced, which has an ultraviolet / infrared ray blocking function.

The ultraviolet / infrared shielding material of the present invention is, for example, a window glass for construction and vehicles, a sunroof, an optical fiber, a prepaid card, a sun visor, a PET bottle, a packaging film, glasses, a storage, a textile product such as clothes, It can be applied to products such as futon cotton, peepholes such as microwave ovens and ovens, greenhouses, greenhouses, cosmetics, and the like, and can be provided with ultraviolet / infrared blocking functions and infrared blocking functions.

EXAMPLES In the following examples and comparative examples, the light transmission spectra were measured using a self-recording spectrophotometer with integrating sphere U-4000 type (manufactured by Hitachi, Ltd.).

Visible light transmittance for the purpose of evaluating transparency.
(JIS R 3106) was measured. Further, the spectral transmittance was measured for the purpose of evaluating the blocking effect of ultraviolet rays and infrared rays, and a spectral transmittance curve showing the relationship between the transmittance and the wavelength was created from the measurement result. In this transmittance curve, the maximum wavelength at which the transmittance is 5% in the ultraviolet region (380 nm or less) is defined as "UV cut wavelength", and the minimum wavelength at which the transmittance is 5% in the infrared region (810 nm or more) is defined as "UV cut wavelength". Infrared cut wavelength ". Furthermore, in order to evaluate the near-infrared blocking effect, a wavelength of 1000 nm
The transmittance was measured and evaluated.

Example 1 The powder used in this example is
The zinc oxide powders A to T having the dope metal content and the average particle diameter shown in Table 1, and the ZnO powder, the CeO ₂ powder, and the ZrO ₂ powder, which also have the average particle diameter shown in Table 1, were used. Zinc powder A~T oxide, ammonia water was added to an aqueous solution containing the chlorides of zinc chloride and the doped metal, to obtain a coprecipitation product, at 400 ° C. The coprecipitation product in a N ₂ atmosphere 1 It was prepared by firing for an hour. Commercially available ZnO powder, CeO ₂ powder, and ZrO ₂ powder were used.

[0043]

[Table 1]

Zinc oxide powders A to T containing doped metal
These were separately used and the powder, the organic resin and the solvent were mixed in the proportions shown in Table 2 to form a coating material, thereby preparing an ultraviolet / infrared ray blocking film forming material. The mixing was performed by adding glass beads and kneading the mixture with a paint shaker while confirming the dispersed state with a particle gauge. For comparison, as a conventional ultraviolet / infrared ray blocking film forming material, a mixed powder obtained by mixing ZnO powder, CeO ₂ powder and ZnrO ₂ powder in the ratios shown in Table 2 was used, and the same coating material as above was used. Turned into

Each of the obtained ultraviolet / infrared ray blocking film forming materials was applied to a glass plate (thickness: 2 mm, visible light transmittance: 91%) with a bar coater and dried at 100 ° C. to give the thickness shown in Table 2. The ultraviolet / infrared blocking film is formed. Transparency of these UV / IR blocking films (total visible light transmittance), UV / IR blocking effect (UV and IR cut wavelengths), and NIR blocking effect (transmittance at 1000 nm)
The results are shown in Table 3.

[0046]

[Table 2]

[0047]

[Table 3]

As can be seen from Table 3, the conventional ultraviolet / infrared ray blocking film has an ultraviolet ray blocking effect, but with respect to the infrared ray blocking effect, it cannot block infrared rays having a wavelength of 2600 nm or less, and has a wavelength of 1000 nm. The infrared blocking effect is inferior despite the fact that three kinds of powders are mixed, such as 80% of infrared rays are transmitted. On the other hand, the ultraviolet / infrared ray blocking film of the present invention uses only one type of zinc oxide powder containing a doped metal, but in addition to a sufficient ultraviolet ray blocking effect, infrared rays having a wavelength longer than 1050 to 1550 nm are used. It is possible to block the infrared rays, and the transmittance of the near infrared rays of 1000 nm is 10 to 37%, and the infrared ray blocking effect including the near infrared rays is high.

(Example 2) Test Nos. 1, 5, 11 of Example 1
An SiO ₂ or ZrO ₂ overcoat layer having the composition and thickness shown in Table 4 was formed on the ultraviolet / infrared ray blocking film obtained in 1. by a sol-gel method. The results of visible light transmittance, ultraviolet and infrared cut wavelengths, and transmittance at 1000 nm of the UV / infrared blocking film thus overcoated are also shown in Table 4. As can be seen from Table 4, even when overcoated with a hard metal oxide, the transparency and ultraviolet / infrared shielding effect of the ultraviolet / infrared shielding film of the present invention are maintained.

Example 3 A glass plate (thickness: 2 mm, visible light) was prepared by using a transparent adhesive on the ultraviolet / infrared ray blocking film on the glass plate obtained in Test Nos. 15 and 20 of Example 1. Transmission 91
%) Was laminated to produce a laminated glass. Table 4 also shows the results of the visible light transmittance, the cut wavelengths of ultraviolet rays and infrared rays, and the transmittance at 1000 nm of this laminated glass. As can be seen from Table 4, the use of laminated glass slightly lowers the transparency, but maintains the ultraviolet / infrared blocking effect as it is.

[Table 4]

Example 4 The powder used in this example is
The zinc oxide powders a to t having the dope metal content and the average particle size shown in Table 5, and the same ZnO powder, CeO ₂ powder, and ZrO ₂ powder used in Example 1 were used. Zinc oxide powders a to t were prepared by the method described in Example 1.

[0053]

[Table 5]

Kneading type molding material for blocking ultraviolet rays and infrared rays
Fee for zinc oxide powder a to c, each powder 10g separately with a small amount of zinc stearate (dispersant), well in the polyvinyl chloride resin is softened in a heat roll 120 ° C. in the ratio shown in Table 2 It was kneaded into and dispersed uniformly in the resin. The softening resin was then sandwiched between two stainless steel plates 0.3 mm thick with a 0.1 mm spacer, 12
After pressing at 0 ° C. for 5 minutes, it was cooled and a film having an ultraviolet / infrared ray blocking function with a thickness shown in Table 6 was formed.

In Table 6, this film is referred to as an ultraviolet / infrared ray blocking film for convenience. The visible light transmittance of this film, UV and infrared cut wavelength, and 1000 n
The transmittance results in m are also shown in Table 6.

With respect to the coating type ultraviolet / infrared ray blocking film forming material zinc oxide powders d to t, these were separately used in the same manner as in Example 1 in the mixing ratio shown in Table 6 with the organic resin and the solvent. An ultraviolet / infrared ray blocking film forming material was prepared by mixing and forming a coating material. For comparison,
ZnO powder, as a conventional UV / IR blocking film forming material,
A mixed powder obtained by mixing CeO ₂ powder and ZrO ₂ powder in the proportions shown in Table 6 was used and made into a paint in the same manner as above.

The obtained ultraviolet / infrared ray blocking film forming material was applied to a PET film (thickness: 75 μm, visible light transmittance: 89%).
It was coated with a bar coater and dried at 100 ° C. to form an ultraviolet / infrared ray blocking film having a thickness shown in Table 6. Table 7 shows the results of the visible light transmittance of these ultraviolet / infrared blocking films, the cut wavelengths of ultraviolet rays and infrared rays, and the transmittance at 1000 nm.

Similar to Example 1, the ultraviolet / infrared ray blocking film of the present invention showed excellent ultraviolet ray blocking effect and infrared ray blocking effect, and also had a high near infrared ray blocking effect. Also, the test No.
The films formed from the kneading-type molding material as in Nos. 1 to 3 also showed the effect of blocking ultraviolet rays and infrared rays. In Test Nos. 1 to 3, the film thickness was large and the transparency was low.
In addition, since the mixing ratio of powder is as small as 1.2 to 9% by weight,
Infrared rays, especially near infrared rays, are less effective,
These can be improved by increasing the blending ratio of the powder.

The transmittance can be lowered.

The ultraviolet / infrared ray blocking film of the present invention is
