Embodiment Construction

[0023] The following references are attached Figure 1-3 The specific implementation process of the method of the present invention will be described in detail.

[0024] Such as figure 1 In the example 1 shown, the laminated vacuum glass to be produced includes: flat glass (such as preferably tempered glass) 1 , an interlayer interlayer 2 of PVB material, and vacuum glass 3 .

[0025] In order to make the laminated vacuum glass of the production target, the laminated vacuum glass structure must first be formed in the above-mentioned manner. Usually, an interlayer interlayer material is placed on one side of the vacuum glass 3 to form an interlayer interlayer 2, and then a piece of flat glass 1 is placed on the outer plane of the interlayer interlayer 2 to form a interlayer vacuum glass structure. In this profession, the operation steps of forming a laminated vacuum glass structure in this way are usually called "lamination (or lamination)".

Abstract

The invention discloses a method for manufacturing laminated vacuum glass. The method comprises the following steps of: placing a lamination intermediate layer material on the surface of one or two sides of a piece of vacuum glass, and placing a piece of flat glass on the outer side plane of the lamination intermediate layer material to form a laminated vacuum glass structure; completely removing gas in the lamination intermediate layer material of the formed laminated vacuum glass structure and gas between the glass and a lamination intermediate layer; filling the laminated vacuum glass structure into a high-pressure kettle, and gradually heating and pressurizing by stages, wherein the maximum temperature in the high-pressure kettle is 100 DEG C to 170 DEG C, and the maximum pressure in the high-pressure kettle is 0.1Mpa to 0.4Mpa; maintaining the temperature and the pressure for 30 to 120 minutes; gradually reducing the temperature and the pressure in the high-pressure kettle to the normal temperature and the normal pressure to obtain the laminated vacuum glass.

Description

technical field [0001] The invention relates to a structure of laminated vacuum glass and a method for making the laminated vacuum glass. Background technique [0002] Laminated vacuum glass (also known as laminated vacuum glass) has been gradually adopted in buildings, thermal insulation doors and windows of refrigeration appliances, locomotive windows, solar energy utilization and other facilities. In addition to maintaining the sound insulation and heat insulation characteristics of vacuum glass, laminated vacuum glass meets the practical needs in terms of safety, especially the requirements of national safety standards. [0003] In principle, the PVB (polyvinyl butyral), EVA (ethylene-vinyl acetate) or SGP (ion polymer) film that exists as an interlayer interlayer in laminated vacuum glass greatly improves the impact resistance and resistance of the glass. Penetrating properties while maintaining high transparency and thermal stability. [0004] Usually, the above-ment...
