A three-layer hollow glass body and its manufacturing method

Abstract

A three-layer hollow glass body and a manufacturing method thereof. The present invention solves the defects of poor consistency of thickness and influence on product quality, poor adhesion and tightness, many manufacturing processes, low production efficiency and high cost in existing similar technologies. Key points of the technical solution: It is composed of two outer glass layers and one middle glass layer that are laminated and glued together. There are hollow cavities between the glass layers. The thickness of the outer glass layer is 3‑6 mm, and the thickness of the middle glass layer is The size of the middle glass layer is 10-12 mm smaller than the size of the outer glass layer. Butyl hot-melt adhesive is used to make a hot-melt adhesive ring. The inner side of the hot-melt adhesive ring is processed with inlaid grooves. The strip circles around the edge of the middle glass layer and is inlaid with the edge. The edges of the two sides and the top side of the inlay groove respectively become the width-limiting parts of the hollow cavity between the glass layers. layer and the intermediate glass layer are bonded together.

Description

technical field [0001] The invention relates to a glass structure for building decoration and a manufacturing method thereof, in particular to a three-layer hollow glass body and a manufacturing method thereof. It is suitable for making doors, windows, indoor and outdoor partition walls or decorative walls with three-layer hollow glass structure. Background technique [0002] The main body of the same type of three-layer insulating glass commonly used at present is composed of two outer glass layers stacked together and an intermediate glass layer between the two outer glass layers. The edge of the middle glass layer is inlaid with metal profiles. The frame is tightly bonded to the two outer glass layers by the adhesive on the outer side of the metal profile frame, and hollow cavities are respectively formed between the two outer glass layers and the middle glass layer. The purpose of setting the three-layer insulating glass body is generally to improve the sound insulation...
