Embodiment Construction

[0039] The content of the present invention will be further described below in conjunction with the accompanying drawings.

[0040] Such as figure 1 and figure 2 Shown, a kind of production method of ultra-thin laminated glass of the present invention, comprises the following steps:

[0041] Step 1: preparing a first glass substrate and a second glass substrate, the thickness of the first glass substrate is greater than the thickness of the second glass substrate;

[0042] In order to ensure the subsequent production of ultra-thin laminated glass, reduce the difficulty of the process, and meet the requirements of light weight, the thickness difference between the first glass substrate and the second glass substrate is preferably at least 0.9 mm, more preferably at least 1.4 mm. mm. Specifically, the thickness of the first glass substrate is at least 1.6mm, more preferably at least 2.1mm; the thickness of the second glass substrate is not greater than 0.7mm, such as 0.7mm, ...

Abstract

The invention relates to the technical field of laminated glass, in particular to ultrathin laminated glass used on vehicles, and provides the ultrathin laminated glass and a production method thereof. The production method includes: preparing a first glass substrate and a second glass substrate; heating and bending the first glass substrate to obtain a first bent glass plate; chemically toughening the second glass substrate to obtain a second straight glass plate; adhering the first bent glass plate, the second straight glass plate and at least one intermediate membrane piece to obtain the ultrathin laminated glass. Bending formation of the second straight glass plate which is thin is not needed, the forming process is simplified, and operability, convenience and continuity in subsequentproduction are determined, the laminated glass is thinned, mechanical and optical properties can meet requirements, and use safety and optical quality of the ultrathin laminated glass are guaranteed.

Description

Technical field: [0001] The invention relates to the technical field of laminated glass, in particular to the ultra-thin laminated glass used in automobiles, and specifically provides a production method of the ultra-thin laminated glass and the ultra-thin laminated glass. Background technique: [0002] With the development of the automobile industry, in order to cope with the increasingly serious energy and environmental protection issues, the lightweight of automobiles has gradually become the trend of application development. The lightweight of the car is to reduce the weight of the car as much as possible under the premise of ensuring the strength and safety performance of the car, so as to improve the power of the car, reduce fuel consumption, and reduce exhaust pollution. For automotive glass, the reduced thickness can also meet the requirements of lightweight to a certain extent. For example, Chinese patent CN103443045B discloses a laminated glass, wherein the thickne...
