Problems solved by technology

[0006] In order to solve the problem that the heat-insulating glass in the prior art is mainly two-way heat-insulating glass, that is, if the outside temperature is higher than the indoor temperature for a long time, a large amount of heat will still be transferred in, and the outside temperature starts to rise rapidly at dusk or after rain. After falling, the indoor heat cannot be dissipated well, and only by opening windows or turning on the air conditioner for interactive heat dissipation or cooling, which will generate a certain amount of energy waste, and the dimming function needs manual control and usually requires external power to provide The interior of the glass is changed, and it is impossible to produce instant sensing and dimming to the external ultraviolet intensity. hot glass substrate

Abstract

The invention relates to the field of glass, in particular to a dimming and heat-insulation glass base plate and a preparation technology thereof. The dimming and heat-insulation glass base plate is composed of an inner base body, a one-way heat conducting layer, a conductive slurry layer and an outer base body. An airtight cavity is formed between the inner base body and the outer body. The one-way heat conducting layer is arranged on the surface, in the airtight cavity, of the inner base body, and the conductive slurry layer is arranged in a cavity between the one-way heat conducting layer and the outer base body, wherein the one-way heat conducting layer is made of a copper-doped polyimide film, and the conductive slurry layer is made of alkaline liquid with the conductivity being 10-50ms / m.

Description

technical field [0001] The invention relates to the field of glass, in particular to a light-adjustable heat-insulating glass substrate and a preparation process thereof. Background technique [0002] Insulating glass is a kind of performance glass, which has a good effect of heat insulation. It is widely used in windows of buildings in hot areas. On this basis, part of the insulating glass also has a dimming function for insulating ultraviolet rays. To block ultraviolet rays from entering the room. [0003] However, the heat-insulating glass in the prior art is mainly two-way heat-insulating glass, that is, if the outside temperature is higher than the indoor temperature for a long time, a large amount of heat will still be transferred in, and the outside temperature will drop rapidly at dusk or after rain. The heat in the rear room cannot be dissipated well, and it can only be dissipated or cooled by opening windows or turning on the air conditioner, which will generate a...
