Double-vacuum-layer glass composite vacuum heat-insulation plate with edge sealed by seal strip and manufacturing method thereof

Abstract

A double-vacuum-layer glass composite vacuum heat-insulation plate with the edge sealed by a seal strip comprises a face plate, a connecting layer and a vacuum cavity and is characterized in that the face plate is a glass plate, the vacuum cavity is a closed cavity formed by welding a low-carbon steel plate and sealing the edge by utilizing a glass solder under the constant pressure and high temperature and performing high-temperature sealing under the vacuum condition, the seal strip is arranged at the welding position of the edge portion of the low-carbon steel plate, the sealing is automatic sealing performed by utilizing an air exhaust opening pre-formed in the vacuum cavity and a low-temperature solder in a vacuum furnace according to a liquid seal principle, the low-temperature solder includes low-temperature metal and an alloy solder, a partition plate is arranged in the vacuum cavity and divides the vacuum cavity into two to form double vacuum layers, and supports are arranged in the vacuum layers. A manufacturing method of the double-vacuum-layer glass composite vacuum heat-insulation plate is simple in process, the manufactured double-vacuum-layer glass composite vacuum heat-insulation plate can overcome the shortcomings of existing heat preservation plates and vacuum heat-insulation plates, and strength and heat-insulation, sound-insulation and fireproof performance can be improved.

Description

technical field [0001] The invention relates to the technical field of building energy conservation, in particular to a double-vacuum-layer glass composite vacuum insulation panel with sealing strip edge sealing and a manufacturing method thereof. Background technique [0002] At present, the materials used for building exterior wall insulation are divided into A-grade thermal insulation materials and B-grade thermal insulation materials. A-grade thermal insulation materials have good fire resistance, but their thermal insulation performance and water resistance are lower than B-grade thermal insulation materials, and there are high prices. Complex construction technology and other issues; B-grade thermal insulation materials have the advantages of low cost, good thermal insulation performance, and mature construction technology, but their durability is not good, heat resistance is poor, and they are easy to burn. Moreover, it can accelerate the spread of fire, so it is forb...
