Description

Technical Field

[0001] This utility model belongs to the field of automotive glass technology, and more specifically, it relates to a transparent heat-insulating glass with a composite structure. Background Technology

[0002] Traditional automotive glass, due to its high thermal conductivity, causes a rapid rise in interior temperature during summer and significant heat loss during winter. This not only increases the energy consumption of the air conditioning system but also affects passenger comfort. To address this issue, researchers have focused on developing transparent heat-insulating glass with excellent thermal insulation properties. Existing automotive transparent heat-insulating glass mainly falls into two categories: vacuum insulated glass (VIG), which reduces heat conduction through a vacuum cavity between two panes of glass; and transparent heat-insulating coated glass, which reduces heat absorption and conduction on the glass surface by reflecting or absorbing infrared radiation through a coating on the glass substrate. Both methods have limitations in terms of abrasion resistance and weather resistance, but also face challenges in manufacturing processes, requiring significant equipment investment and resulting in high costs. The drawbacks of existing technologies are: VIG faces challenges in terms of strength and durability when subjected to the thermomechanical loads of a vehicle in motion; and transparent heat-insulating coated glass struggles to balance light transmission and heat insulation performance, and the abrasion resistance and weather resistance of the coating in the automotive environment cannot meet long-term usage requirements. These technologies have made progress in improving automotive energy efficiency and comfort, but several technical challenges still need to be overcome.

[0003] Existing technology includes a technique called "thermally insulating glass" with publication number JP2006044383. This technique aims to provide thermally insulating glass with a surface hydrophilic layer that maintains hydrophilicity and exhibits excellent durability, transparency, and preservation stability on various glass substrates. It is effective in preventing degradation of various glass substrates by providing a thin metal film with anti-fogging and anti-hazing properties due to moisture, as well as durability. Solution: Thermally insulating glass is formed by lamination of a multilayer film containing one or more noble metal films on the surface of a glass substrate, and coating it with (a) a hydrophilic coating polymer and (b) an alkoxide compound of metals selected from Si, Ti, Zr, and Al formed by hydrolysis and condensation of metal alkoxides. The hydrophilic coating preferably contains a catalyst combined with the hydrophilic polymer of (a) and (d) colloidal silica. The multilayer film containing one or more noble metal-based films is formed by sequentially laminating a dielectric, a noble metal or alloy substrate, a metal substrate, and a dielectric. However, this technology does not address the technical issues and solutions of this application. Utility Model Content
