A kind of vacuum glass with thermal insulation coating and its manufacturing method

Abstract

The invention provides vacuum glass provided with a heat insulation and preservation coating layer and a manufacture method thereof; the glass includes a vacuum glass basal plate and the heat insulation and preservation coating layer, wherein the vacuum glass basal plate comprises a first glass substrate and a second glass substrate, the opposite surfaces of the first glass substrate and the second glass substrate are respectively coated with PVB films, the circumferences of the opposite surfaces of the two glass substrates are connected through a sealing glue and a vacuum inner cavity is formed through vacuumizing; the heat insulation and preservation coating layer coats the other surface, opposite to the first glass substrate, of the second glass substrate. The glass has the dual effects of both heat preservation and noise reduction, the special heat insulation and preservation coating layer is designed and provided, the coating layer composition is reasonable in collocation, the production method is easy to operate, the heat conductivity coefficient is low, and the heat preservation effect is good; moreover, the coating layer can be formed on the surface of the glass only through spraying, the use is simple, the coating layer is not easy to fall off after coating, and the service life is long; the PVB films are arranged in the vacuum inner cavity, the sound insulation and sound absorption effects are good, the economic cost is low, and the use prospect is good.

Description

technical field [0001] The invention relates to a vacuum glass with a thermal insulation coating and a manufacturing method thereof. Background technique [0002] Vacuum glass is to seal the surroundings of two pieces of flat glass, vacuumize the gap and seal the exhaust hole. The gap between the two pieces of glass is 0.1-0.2mm. Generally, at least one of the two pieces of vacuum glass is low-emissivity glass. , so that the heat lost through the conduction, convection and radiation of the vacuum glass is minimized, and its working principle is the same as that of the glass thermos. Vacuum glass is the fruit of the collaboration of glass technology and material science, vacuum technology, physical measurement technology, industrial automation and building science, etc., with a variety of disciplines, technologies, and processes. [0003] Vacuum glass is a new type of energy-saving glass. It is based on the principle of a thermos bottle, and the two pieces of glass are seale...
