Embodiment 1

[0056] The following steps are adopted to prepare safe and energy-saving automotive glass:

[0057] (1) Select cesium potassium glass, PVB film, and aerogel with thicknesses of 3mm, 4mm, and 4mm respectively, and paste Low-e film on one side of the cesium potassium glass;

[0058] (2) Place airgel and PVB film on the cesium potassium glass in step (1) according to the shape of "back";

[0059] (3) Place another piece of cesium potassium glass above. Under vacuum conditions, the temperature is 135°C, the applied pressure is 5MPa, and the temperature and pressure are maintained for 30 minutes to obtain a safe and energy-saving automotive glass. The structure diagram is as follows figure 2 shown. Table 1 is the performance index of the safe and energy-saving automobile glass of Example 1.

Abstract

The invention provides safe energy-saving automotive glass. The safe energy-saving automotive glass is successively composed of glass, an aerogel composite layer and glass, wherein the aerogel composite layer is composed of one or more pieces of aerogel and organic glue pieces on the surrounding side surfaces of the aerogel, and the plurality of pieces of the aerogel are bonded horizontally by theorganic glue pieces on the surrounding side surfaces. The manufacturing method comprises the following steps: (1) laminating: horizontally placing one or more pieces of the aerogel on one piece of glass, then placing the organic glue pieces around the one or more pieces of the aerogel, and placing the other piece of glass on the one or more pieces of the aerogel and the organic glue pieces so asto obtain an assembly; and (2) hot-press forming: subjecting the assembly to hot-press forming at a certain temperature and pressure. The safe energy-saving automotive glass has excellent visible light permeability, heat insulation performance, noise reduction performance, impact resistance and anti-condensation performance, and is especially applicable as front windshield, door glass, sunroof glass and rear windshield of new-energy vehicles.

Description

technical field [0001] The invention relates to the technical field of automobile glass, in particular to a safe and energy-saving automobile glass and a manufacturing method thereof. Background technique [0002] Glass is an airtight material with high transparency, strength and hardness. Glass is chemically inert in the daily environment and will not interact with organisms. Therefore, it has a wide range of uses. The glass used for automobiles in the prior art is mainly used for sealing and lighting, but does not have good effects such as heat insulation, sound insulation and noise reduction, anti-glare, anti-condensation and atomization, and impact resistance. With the rapid development of automobile technology, especially new energy vehicles, people have higher and higher requirements for vehicle endurance and comfort (including light direction, light composition, noise, temperature, etc.) As a lighting material, it is gradually developing in the direction of safety, t...
