Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] see figure 1 , shows a thermochromic laminated glass 10 according to an embodiment of the present invention, which includes two sheets of glass 11 and a thermochromic film 12 sandwiched between the two sheets of glass 11, and the thermochromic film 12 includes a polyvinyl butyral base film And tungsten oxide-doped vanadium dioxide powder dispersed in the polyvinyl butyral base film.

[0016] The two pieces of glass 11 can be made of commonly used glass materials, such as ordinary float glass. In this embodiment, ultra-clear float glass is used, and the thickness can be 1.6mm-3.0mm.

Abstract

The invention relates to a thermochromic laminated glass. The thermochromic laminated glass comprises two pieces of glass and a thermochromic film which is clamped between the two pieces of glass, wherein the thermochromic film comprises a polyvinyl butyral base film and tungsten oxide-doped vanadium dioxide powder which is dispersed in the polyvinyl butyral base film. The invention also relates to a manufacturing method for the thermochromic laminated glass. The thermochromic laminated glass adopts the tungsten oxide-doped vanadium dioxide powder which is dispersed in the polyvinyl butyral base film to form the thermochromic film, the basic structure of the conventional laminated glass is not changed, the investment is low, and a high-efficient color change effect is achieved. Due to the adoption of metal oxides, the thermochromic laminated glass is non-toxic, green, environment-friendly and non-flammable, has high safety and meets the current requirements of energy saving and emission reduction. In addition, the thermochromic laminated glass does not basically change the conventional preparation process when manufactured, is simple in preparation process and low in cost, and is suitable for the fields of building glass, automobile sunroof glass, side window glass and the like.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a thermochromic laminated glass and a manufacturing method thereof. Background technique [0002] Laminated glass is made by pasting two or more pieces of glass under certain temperature and pressure with film, also known as laminated glass or laminated glass. The film is usually a film such as PVB (Polyvinyl butyral, polyvinyl butyral). When the glass is violently impacted and exploded, the tough PVB film will absorb most of the impact energy and shock wave pressure and prevent the impact object from penetrating, so it has anti-theft, bullet-proof, and explosion-proof functions; even if the laminated glass is damaged, the glass fragments will be securely Adhering to the PVB film, it will not fall off and hurt people, so it is especially suitable for the front windshield of automobiles and high-rise building glass; the PVB film in the laminated glass can also absorb more than 99% ...
