が。For window glass of traffic vehicles such as automobiles and various devices,
Heat-reflecting glass, which reflects the heat rays from the sun's solo rays and prevents indoor temperatures from becoming too low, is beginning to be widely used. Metal films are useful as such heat-reflecting glasses in terms of their heat-reflecting properties, and in particular, they allow a suitable amount of visible light to pass through, and their ability to reflect light at wavelengths longer than near-infrared rays is higher than that of other metals. For this purpose, thin films of noble metals such as silver, gold and copper are used. However, such a single layer film of noble metals,
Due to its poor chemical and physical durability, it must be used, for example, by positioning it on the middle air layer side of double-glazed glass to prevent the precious metal thin film from being exposed to the outside, and is therefore used as a single panel. Can not do it. On the other hand, heat-reflecting glass that can be used as a single plate includes tin, titanium, and edge 1
~． There is a glass plate whose surface is coated with a film made of a type of metal oxide such as chromium or iron, or a mixture thereof, and this type of heat-reflective glass has good chemical and physical durability. , with some exceptions (f) indium oxide with one heave of B, tin oxide doped with antimony), they have the disadvantage that their heat ray reflection performance is inferior to that of noble metals. Temporary heat-reflecting glass with improved IN abrasion resistance and chestnut resistance, and which can be used as a single sheet, is known to be coated with a Ti coating, a chromium coating, or an Inconel coating. However, it has excellent wear resistance.

のは、耐酸性。Surface 1: Poor acidity and alkali IJ resistance; products coated with Cr have excellent acid resistance and VJ-T alkalinity, but are inferior in wear resistance, and the Cr film itself has brittle characteristics, causing internal stress in the film. This has the disadvantage of reducing the strength of the glass itself, and those coated with Inconel coating are acid resistant.

が現状である。Although its alkali resistance is superior to those coated with Ti, it has the disadvantage of inferior abrasion resistance.It still has sufficient abrasion resistance, acid resistance, alkali resistance, etc. At present, it is not possible to obtain highly heat-reflecting glass.

た熱線反射ガラスが上記目的を達成しうろことを見出し
、本発明として提案するに到ったものである。In view of the above points, the present inventor has conducted research with the aim of providing a heat-reflecting glass with even better abrasion resistance, acid resistance, and alkali resistance without reducing the strength of the glass itself. We have discovered that a heat ray reflective glass in which the glass substrate surface is coated with a Ti coating as the first layer 1 and a Cr coating as the second layer counting from the glass substrate surface side can achieve the above object, and propose it as the present invention. It has arrived.
以下、本発明を更に詳細に説明する。The present invention will be explained in more detail below.
図において、１はガラス基体、２はガラス基体面側から
数えて第１層目のＴｉ被膜、３はカラス基体面側から数
えて第２層目のＣｒ被膜を示す。In the figure, 1 is a glass substrate, 2 is the first layer of Ti coating as counted from the glass substrate surface side, and 3 is the second Cr coating layer as counted from the glass substrate surface side.
本発明におけるカラス基体は、ソーダライムガラス、ホ

が使用できる。As the glass substrate in the present invention, various glass substrates such as soda lime glass, borosilicate glass, and other types of glass substrates such as plates, tubes, rods, and blocks made of various types of silk can be used.
本発明におけるガラス基体面側から数えて第１層目に形

劣り好ましくなく、又ｉ＋ｎｏ入より厚いと透過率か著
るしく低下して透視性を有する熱線反射ガラスとして好
ましくなくなる。The Ti coating formed in the first layer counting from the glass substrate surface side in the present invention is a coating made of metal Ti,
The optimum film thickness is in the range of 85λ to 400i. If the thickness of this Ti coating is thinner than 85mm, the adhesion between the Ti coating and the glass surface will be poor, and the abrasion resistance and scratch resistance will also be poor, which is undesirable.If it is thicker than the i+no coating, the transmittance will decrease significantly. This decreases and makes it undesirable as a heat-reflecting glass with transparency.
なお、上記金属Ｔ１被膜には、１０％以下の他の成分を
含ませることができる。Note that the metal T1 coating may contain 10% or less of other components.

か生きてこなくなり好ましくない。In addition, the coating formed at the second Fm opening counted from the glass substrate surface in the present invention has high chemical resistance 2 mechanical strength and excellent durability, and has excellent adhesion to the first Ti coating. A superior Cr coating is selected. The thickness of this Cr film is 30A
A range of ~150Δ is optimal. If this film thickness is thinner than 30Δ, the protective effect on the first layer Ti film will be weak, and the effect of -H on acid resistance and alkali resistance will be small, which is not preferable.
Also, if it is thicker than 150A, scratches on the Cr coating will be more noticeable, and the scratching effect will not survive, which is not preferable.

Since both layers are made of metal, there is no need to change the atmosphere of the vacuum chamber, and there is little difference in the film formation conditions for each layer, allowing for semi-continuous or continuous production using sputtering or vacuum evaporation methods. This is advantageous because it allows you to
