Stone composite vacuum panel with sealing strips and mounting holes and manufacturing method thereof

Abstract

A stone composite vacuum panel with sealing strips and mounting holes comprises a surface plate, a connecting layer and a vacuum chamber and is characterized in that the mounting holes are combined with pumping holes and penetrate through the whole composite plate, the surface plate is made of natural stone or artificial stone, the connecting layer is arranged between the surface plate and the vacuum chamber for connecting the surface plate and the vacuum chamber as a whole, the vacuum chamber is a closed chamber formed by a low-carbon steel plate subjected to glass soldering edge sealing at atmospheric pressure and high temperature and high-temperature opening sealing in vacuum, welding portions of the edge of the low-carbon steel plate are provided with the sealing strips, the opening sealing is the automatic sealing of the pumping holes preformed in the vacuum chamber with low-temperature solder in a vacuum furnace according to the principle of liquid seal, the low-temperature solder comprises low-temperature metal and alloy solder, and supporting members are arranged in the vacuum chamber. A manufacturing method of the stone composite vacuum panel with the sealing strips and the mounting holes is simple in process. The strength and thermal insulation, sound insulation and fireproof performance of the stone composite vacuum panel with the mounting holes can be improved.

Description

technical field [0001] The invention relates to the technical field of building energy saving, in particular to a stone composite vacuum panel with sealing strips and installation holes 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 forbidden to use organic therm...

AI Technical Summary

Problems solved by technology

[0005] Stone has good wear resistance and durability, and the surface is beautiful and decorative after processing. It is a high-grade building decoration material, but its acid resistance is weak, thermal insulation performance is poor, and it is heavy. The strength of ultra-thin stone is low. , The insulation material compounded with polyurethane foam has poor fire resistance
