AI Technical Summary

Technical Problem

In existing technologies, the high transmittance of windows in new energy vehicles allows solar heat to enter the vehicle, reducing passenger comfort. At the same time, the high cost of dark-colored PVB films increases vehicle costs.

Method used

The laminated glass design includes a first glass plate, an adhesive layer, and a low-transmittance heat insulation layer. The low-transmittance heat insulation layer contains an absorption functional layer and an infrared reflection layer, which reduces visible light transmittance and total solar energy transmittance, replacing the dark-colored PVB film.

Benefits of technology

It achieves low-cost privacy protection and high heat insulation, reduces heat entering the vehicle, eliminates the need for sunshades, and improves user experience and visual comfort.

Abstract

Provided in the present application are laminated glass and a vehicle. The laminated glass comprises a first glass plate, a bonding layer, a second glass plate, and a low-transmittance thermal insulation layer, wherein the low-transmittance thermal insulation layer comprises at least one absorption functional layer, and the laminated glass has a visible light transmittance TL1 of less than or equal to 15%, a total solar transmittance TTS of less than or equal to 20%, and an emissivity e of less than or equal to 0.5 measured from one side of the low-transmittance thermal insulation layer. In the present application, by providing the low-transmittance thermal insulation layer, the laminated glass has a relatively low visible light transmittance TL1 and a relatively low emissivity e, and a deeply colored PVB film in the related art can be omitted, thus enabling the laminated glass to have the effects of low costs, simple manufacturing and production, and privacy protection. In combination with an infrared reflective layer, the laminated glass has a lower total solar transmittance TTS and can thus insulate heat better, and the provision of a sunshade curtain in a vehicle is omitted, thereby obtaining a larger height space inside the vehicle.
