The present invention relates to a method for producing a transparent multilayer composite plate having a high visible light transmittance and a large ultraviolet and heat ray shielding effect. still,
In the present invention, the heat ray has a wavelength of 800 to 2,500 nm.

させることになる。2. Description of the Related Art Conventionally, sunlight rays incident from so-called openings such as window glasses of buildings and vehicles, top lights, doors, etc. include ultraviolet rays and infrared rays in addition to visible rays.
It has been pointed out that the ultraviolet rays contained in the sun rays cause deterioration phenomena such as fading and deterioration of strength on printed matter, plastics, rubber, clothes, etc., and in recent years, have a bad influence on the human body. . In addition, 800 out of infrared
Near-infrared rays of up to 2,500 nm are called heat rays and are a cause of heat, and when they enter through the openings, the cooling effect is reduced.

る。In order to solve such problems, as a technique for imparting a function of shielding the ultraviolet ray and the heat ray to the transparent material used for the opening, the material itself may contain an ultraviolet absorber or a coloring component, or the surface of the material may be covered. It is known that a thin film having these functions is formed, or a film having these functions is attached, or used as an adhesive component.

Heat ray reflective glass with a metal oxide thin film formed on the glass surface to improve the surface reflectance must use equipment that requires high vacuum and precise atmosphere control, resulting in poor mass productivity and versatility. Not only is it poor and costly, it has little UV shielding effect, and it causes reflection pollution and radio wave interference, which is a problem.

ていない。There is also a method of sticking various films such as an ultraviolet absorbing film, a coloring film and a metal vapor deposition film on the glass surface, but there is a problem in durability under severe conditions such as a vehicle. For laminated glass that is thermocompression-bonded by sandwiching a film having a function of blocking ultraviolet rays and heat rays between the glasses, a manufacturing apparatus suitable for the size is required, and large-sized laminated glass and bent laminated glass Is very difficult to manufacture. Other transparent plates such as acrylic plates and polycarbonate plates used for various openings also have many problems similar to the case of glass, and a material that meets the market demand has not yet appeared.

In the present invention, the thickness of the transparent plate is not particularly limited, but varies depending on the material of the transparent plate, but is generally in the range of about 2.0 to 20.0 mm. The gap between the transparent plates formed by the plurality of transparent plates is not particularly limited, but is 0.5 to 10.0 m.

One or more of them are used in consideration of the optical characteristics of the transparent plate used.

However, if the amount added is too large, the physical properties of the injected resin after curing may be impaired. Also, the visible light transmittance is reduced. The addition amount of the heat ray-shielding agent to the injected acrylic resin is appropriately determined according to the relationship between the type of transparent plate used and the gap and the visible light transmittance, but the preferable addition amount is 1% or less of the weight of the injected acrylic resin. , Preferably about 0.2-0.8%.

Therefore, the average particle size of the heat ray shielding agent is
Fine dispersion of less than 0.2 μm, preferably 0.1 μm or less is preferable for obtaining a sufficiently transparent composite plate. The heat ray-shielding agent may be dispersed by a conventionally known method as long as it does not impair the physical properties of the acrylic resin.

The multilayer composite plate according to the present invention has a small haze and is transparent, and has a large effect of shielding ultraviolet rays and heat rays.
It has an effect that only visible rays of sunlight can be effectively taken in, and is suitable as a material used for the opening. Further, when glass is used for the transparent plate, the injected resin is firmly adhered, so that if the glass breaks, it has the effect of preventing the glass from scattering. If a composite plate using a glass plate and a resin plate is used, it is possible to impart scratch resistance to a part using only the resin plate and penetration resistance to a part using only glass. effective.
