。又自動り[Technical Field] The present invention provides a material for use in automobiles and other vehicles that causes less skin damage during collisions, has excellent penetration resistance, has heat ray reflection properties, and also has excellent heat resistance, water resistance, and light properties. The present invention relates to heat-reflecting safety glass that is most suitable for use in vehicles and buildings, and in particular, heat-reflecting safety glass that is most suitable for use in automobile window safety glass. [Prior art and its problems] A polyvinyl butyral film (hereinafter referred to as Pv) was applied to two glass plates.
It is abbreviated as B film. ) has been widely used in automobile windshields, but the safety of such conventional laminated glass,
In particular, as an improved skin injury during a collision, the fit
Place a plastic film such as polyethylene terephthalate on the indoor side of the glass plate or laminated glass plate.
) A safety glass bonded with a VB film has been proposed, for example, in Japanese Patent Application Laid-Open No. 19314/1983. Such safety glass is made of highly unbreakable plastic on the indoor side.
Although the film has the advantage of reducing the risk of injury to passengers from glass fragments even if the glass plate is broken, it has the following drawbacks. That is, if a plastic film is bonded to a glass plate or a laminated glass plate using F) V r3 film, if a boiling test is performed, l) V B film will foam or hard objects will form on the surface of the plastic film. It was discovered that when a plastic film is applied, it easily causes indentation scratches, which remain as permanent deformation, and that when heated, the surface of the plastic film becomes uneven, deteriorating its optical properties. This difficulty is thought to be caused by the fact that the PVB film has poor water resistance, and (1) the VB film starts to soften at about 60° C. because it is plastic. [Problems to be Solved by the Invention] The present invention provides heat resistance, water resistance, optical properties, and tear resistance without the disadvantages of foaming, push-in scratches, and surface unevenness caused by heating as described in Section 2 above. 1. To provide safety glass that has excellent permeability and heat ray reflection performance.
This is the first objective. [Means for Solving the Problems] The present invention has been made to solve the above-mentioned problems, and includes applying a heat-reflecting coating to the indoor side surface of a glass plate, and applying a heat-reflecting coating to the surface of the heat-reflecting coating. The present invention provides a heat-reflecting safety glass characterized by laminating a tear-resistant plastic film. The present invention will now be described in more detail. Figures 1 to 5 show specific examples of the heat-reflective safety glass according to the present invention. In Figure 1, l is a glass plate, 2 is a heat-reflective coating, 3 is a tear-resistant plastic film, and 4
indicates heat-reflective safety glass. As the transparent glass plate l in the present invention, soda-lime silicate-based glass plate glass manufactured by the float method or other types of plate glass manufacturing methods, float glass plate, heat ray absorbing glass plate, etc. are of course used. It is not limited to this. The thickness of such a glass plate is approximately 1.8 to 10 mm, but particularly for automobile window glass, the thickness is approximately 2.0 to 5.0 mm. [About 1 mm is preferable. The glass plate may be a flat plate, or may be bent into a desired shape, or may be subjected to peripheral reinforcement processing, semi-reinforcement processing, partial reinforcement processing, etc. as necessary. The entire surface may be reinforced. Also automatic

るいはサンルーフ川ガラスとして大変イｆ用である。In the case of glass, a concealing band 5 may be formed by printing and baking ceramic color frit on the periphery of the glass plate 1 as shown in FIG. In the present invention, a heat ray reflective coating is formed on the glass plate surface. This heat ray reflective coating is formed on the surface of the glass plate that becomes the indoor side when the glass plate is attached to the window of an automobile, other various vehicles, or buildings in order to protect the layer. As this heat ray reflective coating, tin oxide coating, sb, F

An alloy film such as i-Cu is used. In the case of the above-mentioned metal coatings, alloy coatings, inorganic coatings, etc., tin oxide, titanium oxide, indium oxide, zinc oxide, tungsten oxide, or aluminum oxide is added to the surface of the metal coating to particularly increase durability and visible light transmittance. , forming a non-absorbable dielectric coating such as bismuth oxide, zirconium mide, zinc oxide, etc., or sandwiching a metal coating with two absorptive dielectric coatings from below to form a three-layer system. is preferred. For example, titanium oxide/titanium oxide/
Examples include a three-layer system of Ag/titanium oxide, a three-layer system of zinc oxide/g/zinc oxide, and tungsten oxide 3g/tungsten oxide. The heat ray reflective coatings listed above are merely representative examples, and may have been multilayered, multilayered with different types of coatings, composite films, or made of other materials. You may also choose a coating. When such a heat ray reflective coating is exposed on the end surface of the safety glass,
Because this coating itself does not have sufficient water resistance, heat resistance, chemical resistance, corrosive gas resistance, etc., the heat ray reflective coating may discolor.
Since the tear-resistant plastic film may peel off, for example, as shown in Figures 3 to 5, the heat ray reflective coating should have a margin 6 of at least 3 mm, particularly preferably 6 to 20 mm, in width from the end surface of the glass plate. It is preferable that it be provided and formed on the glass plate surface. In this way, the glass plate 1 and the tear-resistant plastic film 3 are directly bonded to each other at the periphery of the safety glass, so water, chemicals, gas, etc. can enter from the edge of the safety glass and corrode the heat ray reflective coating. It is possible to reduce the risk of being damaged and improve practical performance. In addition, the tear-resistant plastic film used in the present invention is highly transparent and has a permeability of 1'1, which means that the film does not break when an impact is applied to it and has a moderate amount of elongation. It has shock absorption and high chemical durability, and its surface has scratch resistance, abrasion resistance,
Preferred are plastic films that have good stain resistance and scratch resistance. For example, laminated plastic films with self-healing thermosetting polyurethane films, polyethylene terephthalate films, nylon films, etc. and adhesive layers such as polyurethane films, polyvinyl butyral films, ethylene-vinyl acetate copolymers, or glass. A polyethylene terephthalate 5 nylon film with an adhesive interlayer on the side that is laminated with the plate, a tear-resistant plastic film such as self-healing thermosetting urethane, or a single-layer or multi-layer film of polyurethane, such as a glass plate. Typical examples include a tear-resistant Plus Deck film having a thermoplastic urethane layer on the laminated side, and a tear-resistant plastic film made of surface-modified thermoplastic urethane. Among these, a thermosetting urethane film whose exposed surface has self-healing properties, or a tear-resistant plastic that has the same thermosetting urethane layer on the interior side and an adhesive layer on the glass plate side. Films are optimal because they have a good ability to follow the bending shape of a glass plate even when the glass plate is subjected to bending stress, and even if they are scratched, they can be repaired. Crosslinked polyurethane is suitable as a polyurethane film having such a surface. In order to improve stain resistance, the surface may be subjected to surface treatment such as impregnating a polyfunctional acrylic or methacrylic monomer and polymerizing it with ultraviolet rays or the like. Polyurethane films are also required to have mechanical properties such as rt resistance, similar to those required for interlayer films in rNI-rated glass, but these mechanical properties are superior to those of thermoplastic polyurethane and certain types of cross-linked polyurethane films. This is achieved by using When using curved polyurethane, the tear-resistant transparent plastic film should be 3a as shown in Figures 2-4.
, 3b has a two-layer structure. If the latter polyurethane is employed, and it has self-healing properties, the tear-resistant transparent plastic film can be composed of only one layer of this polyurethane, as shown in FIG. Cross-linked polyurethanes having such self-healing properties and mechanical properties are also described in Japanese Patent Application No. 18692/1982 and Japanese Patent Application No. 19266/1982. Such a crosslinked polyurethane sheet or film may be adhered to a glass plate with an adhesive if necessary, or if it has high adhesiveness, it may be directly adhered to a glass plate. The thickness of such tear-resistant plastic film is 0.2 to 3.0 to obtain sufficient penetration resistance and impact absorption resistance.
Approximately mm is preferable. In manufacturing the heat-reflecting safety glass of the present invention, a glass plate cut into a desired shape is used, and the glass plate is cut into a flat plate, or this glass plate is subjected to gravity bending, press bending, etc. The glass plate is bent into the desired shape using the 3D process or the air form process, and further strengthened as necessary to prepare a glass plate for lamination.The glass plate is thoroughly washed, dried, and dust removed. A desired heat-reflecting coating is formed on this surface by an appropriate coating forming method such as sputtering, vacuum deposition, vacuum deposition, spraying, CVD, or CI-1). Note that after forming the heat ray reflective coating on the glass plate, bending or reinforcing may be performed as necessary. Further, if necessary, the peripheral edge of the heat ray reflective coating may be trimmed over a predetermined distance Ill. Note that a heat ray reflective coating is formed); 1. Masking of a predetermined width is applied to the periphery of the glass plate, and a blank area, that is, an area where the heat ray reflective coating is not formed, is provided at the periphery of the glass plate. Good too. Next, this glass plate and a tear-resistant plastic film are stacked, and if necessary, a cover glass plate is stacked on top of the plastic film as a pressing plate, and this laminate is placed in a crimping tool to degas it, and if necessary, heated. Typical examples include preliminary crimping, then taking it out of the crimping device, or placing it in an autoclave with the crimping device in place and thermocompression bonding, but the method is not limited to this, and the method of crimping laminated glass can also be used. can. In the present invention, a heat-reflecting q-1 safety glass having desired characteristics can be obtained by appropriately selecting a heat-reflecting coating. For example, for the front window, side window, or rear window of a car, the visible light transmittance of heat-reflective safety glass is 70%.
The heat-reflecting coating can be selected to achieve the desired shielding effect, e.g.
A heat reflective coating can be selected to provide a visible light transmittance of 5%. [Examples] Examples of the present invention will be described below. Example 1 A bent glass plate (soda lime silicate glass plate) of 749 + nm x 1430 mm x 3.5 mm was prepared, and a heat ray reflector made of indium oxide containing 800 tin was applied to the entire surface of one side of the glass plate by sputtering. A film was formed. The entire circumference of the heat-reflecting coating on this glass plate was trimmed along the periphery of the glass plate over a distance of 11 cm by acid etching. on the other hand,
A tear-resistant plastic film was prepared by forming a heat l-1 (FFI polyurethane adhesive layer (adhesive layer thickness: 0.03 mm) on one side of a cross-linked polyurethane film with a thickness of 11 mm and 0.8 mm. 2. Overlap the glass plate and the tear-resistant plastic film so that the surface on which the heat ray reflective coating is formed on the glass plate and the thermoplastic polyurethane adhesive layer surface of the tear-resistant plastic film are aligned to form a laminate. This was then placed in a rubber bag, deaerated and pre-crimped, and then placed in an autoclave for main crimping.The performance test results of Sample 1 thus obtained were
Shown in the table. Example 2 A bent glass plate (soda-lime silicate glass plate) of 749 + nm x 1430 mm x 3.5 mm was heated to a glass plate of 450 nm by sputtering on the entire surface of one side of the glass plate. A heat-reflecting coating was formed on the glass plate.The entire circumference of the heat-reflecting coating on the glass plate was trimmed along the periphery of the glass plate over a length of 1 cm using an acid etching method.Meanwhile, a cross-linked polyurethane film with a thickness of 0.8 mm was trimmed. A tear-resistant plastic film was prepared with a thermoplastic polyurethane adhesive layer (adhesive layer thickness: 0.03 mm) formed on one side of the film.The exposed surface of the cross-linked polyurethane was pre-impregnated with a polyfunctional acrylic monomer. , surface modified by ultraviolet irradiation q・t was used.-Ll?L! Heat ray reaction q of glass plate
The glass plate described in 1-1 and the tear-resistant plastic film 1 are stacked so that the surface on which the coating 1 is formed and the thermoplastic polyurethane adhesive layer surface of the tear-resistant plastic film 1 are aligned to form a laminate. This was then placed in a rubber bag, deaerated, and subjected to preliminary pressure bonding, and then placed in an autoclave for main pressure bonding. Table 1 shows the f1 ability test results of Sample 2 thus obtained. Table 1 [Effects of the Invention] As explained above, the heat ray reflective safety glass of the present invention can obtain the desired heat ray reflective performance, has sufficient iΦi impact resistance, and is resistant to scratches on the surface. It also has sufficient chemical durability, does not reduce adhesive strength, and even if the safety glass is damaged by impact, the tear-resistant plastic film and the glass plate will not separate. It is possible to prevent glass fragments from scattering as much as possible. The safety glass of the present invention is most suitable for use as a glass plate for windows of automobiles or other types of automobiles, or glass plates for windows of buildings where there is a risk of collision with a human body. Above all, the safety glass of the present invention has the plastic film side placed on the city side of the automatic i1i, and the glass plate! 1 (By arranging it on the outside, it is possible to reduce damage to the human body and brain damage of the driver and crew members in the event of a collision, resulting in a high level of safety. Also, the heat ray reflective safety glass of the present invention Since the film has sufficient moisture resistance and heat resistance, it is possible to reduce the deterioration of the optical performance of the heat ray reflective coating and the discoloration of the film.In particular, the heat ray reflective safety coating of the present invention Glass has high heat-reflecting performance, reduces cooling load, and is highly safe, making it ideal for use as glass for automobile front windows, rear windows, side windows, or sunroof windows.In particular, glass for automobiles has a heat-reflecting safety feature. When using glass, the performance of the heat-reflecting coating is weak, so a heat-reflecting coating must be formed on the inner surface of the laminated glass, which is made by bonding two glass plates with a plastic interlayer. When required, there was a drawback that it was difficult to curve the two sheets of raw glass for laminated glass accurately and without mismatching, but according to the present invention, only one glass sheet is required. There is no need to bend two glass plates into the same shape, and hot-wire anti-91 safety glass can be obtained at a high yield and at low cost.In particular, the present invention requires only one glass plate to be bent. Bending is much easier than bending a glass plate, and it can be used to bend hot wires of complex shapes.
Safety glass can be easily obtained and is very useful as windshield, rear glass, or sunroof glass for automatic vehicles that require complex shapes.
