Three-layer hollow glass main body and its production method

Abstract

The invention discloses a three-layer hollow glass main body and its production method, in order to solve the problems of poor thickness consistency and negative influence on product quality, poor adhesion, tedious production process, low production efficiency and high cost in the prior art. The hollow glass main body is characterized in that the main body is composed of two lateral glass layers and one middle glass layer which are arranged in a laminated manner and adhered together, and hollow cavities are arranged among the glass layers, wherein the lateral glass layers have thicknesses of 3-6 mm, the middle glass layer has a thickness of 6-12 mm, and the size of the middle glass layer is respectively smaller than the sizes of the lateral glass layers by 10-12 mm, a hot melt adhesive strip ring is made of a butyl hot melt adhesive, an embedding groove is formed at the inner side surface of the hot melt adhesive strip ring, the hot melt adhesive strip ring surrounds the peripheral edge of the middle glass layer and matches with the edge in an embedded manner, the edges at the tops of two sides of the embedding groove are width limiting parts of the hollow cavities among the glass layers, and the two lateral glass layers and the middle glass layer are adhered together by the hot melt adhesive strip ring through a specific hot-pressing technology.

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...
