Embodiment 1

[0030] A kind of automobile laminated glass air bubble elimination process of the present invention comprises the following steps:

[0031] (1) First prepare the special tools and auxiliary materials for repairing and eliminating air bubbles: 1. Light holders for placing multi-curvature automotive glass; Partial heating of the glass, light and flexible; 3. Customized special-shaped stainless steel brazing, with a thickness of 0.5mm, one end is semicircular, used to squeeze the filler, and the other end is tapered, used to stab even dense air bubbles Bubbles in Zone 4; 4. Used for injecting plastic injection syringes; 5. PVB edge material, used as filler in crack 6; 6. Liquid injection molding agent used for high-pressure post-sealing.

[0032] (2) Implementation steps: 1. Place the glass on the light stand, power on the self-air temperature-adjusting plastic welding torch, and the hot air at the air outlet will quickly heat up to about 150°C, and then direct the air outlet ver...

Abstract

The invention provides an automobile laminated glass bubble eliminating technology. A comprehensive technical means is adopted, meanwhile, the thermodynamic property of a PVB (polyvinyl butyral) film is combined, high-difficulty one-time repair for local intensive bubbles of sharp and steep glass is realized, the field operability is high, the efficiency is high, time and labor are saved, and the technology has higher core competence in the industry, can meet use requirements of part of medium and high-end clients and has greater market potential.

Description

technical field [0001] The invention belongs to the field of automobile glass manufacturing, and in particular relates to a process for eliminating air bubbles in automobile laminated glass. Background technique [0002] With the increasing level of people's consumption, family cars of different grades can no longer meet people's needs for leisure and entertainment. In recent years, various multifunctional new energy electric vehicles, tourist vehicles of different styles, Very casual style golf sightseeing car and so on. The diversity of automobile styles and styles determines the diversity of corresponding glass styles and the complexity of appearance shapes and curved surfaces. This is especially reflected in electric vehicles and sightseeing vehicles. The spatial surface of this type of glass is complex, the end is sharply curved, and the spherical surface is relatively large, which makes it very difficult to bake and bend. Therefore, the glass edge fits relatively poor...
