Embodiment 1

[0038] Such as figure 1 As shown, a low-emissivity coated insulating glass provided in this embodiment includes an outer glass substrate layer 100, a first sputter-deposited nano-film layer 200, a second sputter-deposited nano-film layer 300, The inner glass substrate layer 400, the top and the bottom of the outer glass substrate layer 100 and the inner glass substrate layer 400 are installed with a first reinforcing mechanism 600 through the first sealing member 500, and the two sides of the outer glass substrate layer 100 and the inner glass substrate layer 400 pass through The second sealing member 700 is equipped with a second reinforcement mechanism 800, and the first sealing member 500 and the second sealing member 700 enclose the first sputtering deposited nano-film layer 200 and the second sputtering deposited nano-film layer 300. forming a closed cavity 900;

[0039] The outer glass substrate layer 100 includes a first outer glass substrate 110, a first low-radiation...

Embodiment 2

[0048] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that a layer of explosion-proof film layer 140 is provided on the side of the first outer glass substrate 110 away from the first low-emissivity mucous layer 120 . The airtight cavity 900 is filled with dry air or an inert gas, and the inert gas is preferably argon. The explosion-proof film layer 140 is glued on the surface of the first outer glass substrate 110 by pressure-sensitive adhesive, which plays the role of explosion-proof and heat insulation, and can be directly torn off during the use of the insulating glass.

Embodiment 3

[0050] Such as figure 1 As shown, in this embodiment, on the basis of Example 1, the preparation method of the first low-radiation mucous layer 120 and the second low-radiation mucous layer 420 specifically includes the following steps:

[0051] S1. Preparation of matrix film material: according to parts by weight, weigh 135 parts of phenylpropylene, 23 parts of n-butyl methacrylate, 13 parts of acrylic acid, 4 parts of sodium carbonate, 2 parts of sodium lignosulfonate, and 480 parts of deionized water, Stir mechanically at 62°C for 2.5 hours, add dropwise 26wt% sodium hydroxide solution to pH 7~8, vacuum demulsify, filter under reduced pressure, and the obtained filtrate is the matrix membrane material;

[0052] S2. Preparation of radiation-reducing filler: According to parts by weight, 32 parts of inorganic nano-powder with infrared blocking effect, 8 parts of nano-titanium dioxide powder, 7 parts of dispersant, 2.2 parts of light stabilizer, and 48 parts of solvent ethyl a...

Abstract

The invention discloses low-radiation coated hollow glass and a coating process thereof, and relates to the technical field of hollow glass. The low-radiation coated hollow glass comprises an outer glass substrate layer, a first sputtering deposition nano-film layer, a second sputtering deposition nano-film layer and an inner glass substrate layer which are sequentially arranged from outside to inside, wherein first reinforcing mechanisms are mounted at the top and the bottom of the outer glass substrate layer and the inner glass substrate layer through first sealing pieces, second reinforcing mechanisms are mounted on the two sides of the outer glass substrate layer and the two sides of the inner glass substrate layer through second sealing pieces, and the first sealing pieces and the second sealing pieces form a closed cavity for an area defined by the first sputtering deposition nano-film layer and the second sputtering deposition nano-film layer. The low-radiation coated hollow glass has good sound insulation, heat insulation and stability and has high reflectivity to infrared rays with the wavelength of 4.5-25 microns, the coating process comprises three procedures, namely, surface treatment, adhesive pressing and magnetron sputtering coating, harsh conditions are not needed, and the quality is controllable.

Description

technical field [0001] The invention relates to the technical field of hollow glass, in particular to a low-radiation coated hollow glass and a coating process thereof. Background technique [0002] Insulating glass has the advantages of heat insulation, sound insulation, anti-theft, fire prevention, etc., and is mostly used as architectural glass; with the development of technology, the speed of high-speed trains such as subways and bullet trains is getting faster and faster, and sound insulation, heat insulation, safety and comfort, etc. need to be considered Performance, insulating glass is increasingly used. At the same time, in order to achieve the performance of controlling the color of the glass, the transmittance and reflectance of sunlight, heat insulation, and ultraviolet transmittance, the actual product will also be coated with one or several layers of metal and non-metallic substances on the surface of the glass substrate. film layer. [0003] The patent appli...
