Embodiment 1

[0019] In the 600t / d float glass production line, the width of the glass plate is 4200mm, the thickness of the glass plate is 5mm, the speed of the glass plate is 9m / min, and the temperature of the glass plate surface at the exit of the return kiln is 50°C.

[0020] The coating solution is composed of nano-silicon dioxide with a mass concentration of 0.1, 0.5% nano-titanium dioxide, 0.1% nano-iron oxide, and the rest is ethanol. The configuration process of the coating solution mixes various reactive substances together, and there is no order of addition , Stir evenly at room temperature, and the coating solution needs to be heated to the same temperature as the glass substrate to be coated.

[0021] The length of the coated rubber roller is consistent with the width of the glass plate, and the contact depth between the bottom end of the coated rubber roller and the upper surface of the glass is 0.1mm (that is, the bottom end of the rubber roller contacts the glass surface and ...

Embodiment 2

[0023] In the 450t / d calendered glass production line, the width of the glass plate is 3300mm, the thickness of the glass plate is 5mm, the speed of the glass plate is 9m / min, the temperature of the glass plate surface at the outlet of the return kiln is 80°C, and the length of the coating roller is consistent with the width of the glass plate. The contact depth between the bottom end of the coating roller and the upper surface of the glass is 0.5mm. The coating solution contains 1.5% nano-silicon dioxide, 2% nano-titanium dioxide, 0.5% nano-iron oxide, and the rest is isopropanol. The film layer is at room temperature Cured, the thickness is about 100nm, and it blocks about 85% of ultraviolet rays measured according to the ISO9050 standard.

Embodiment 3

[0025] On a 300t / d flat-drawn glass production line, the width of the glass plate is 3300mm, the thickness of the glass plate is 5mm, the speed of the glass plate is 9m / min, the temperature of the glass plate surface at the exit of the return kiln is 100°C, and the length of the coating roller is consistent with the width of the glass plate , the contact depth between the bottom end of the coated rubber roller and the upper surface of the glass is 1mm, the coating solution contains 3% nano-silicon dioxide, 5% nano-titanium dioxide, 1% nano-iron oxide, and the rest is acetone, and the film layer is cured at room temperature. The thickness is about 150nm, and it blocks about 90% of ultraviolet rays measured according to the ISO9050 standard.

Abstract

The invention relates to a method for roll-painting anti-ultraviolet coated glass online. The method comprises the steps of mounting roll-painting equipment with a coating rubber roller (1), an electric carving stick (2) and a slurry tank (4) between an annealing kiln (5) and a cold-end cutting part (6) of a glass production line, and filling the slurry tank with a sol solution which comprises the following raw materials in percentage by weight: 0.1-3 percent of nano silicon dioxide, 0.5-5 percent of nano titanium dioxide, 0.1-1 percent of nano ferric oxide and the balance being organic solvent, wherein the length of the coating rubber roller is consistent with the width of a glass plate; adjusting the contact depth of the bottommost end of the coating rubber roller and the upper surface of the glass to be 0.1-1mm and the moving speed of a glass substrate to be 9m / min, roll-painting the surface of the float glass at the temperature of 50-100 DEG C with coating slurry, and performing cooling and curing on a film layer under the normal temperature. The method has the advantages of simple technology, stability, reliability, uniform film layer, low cost, high efficiency, suitability for large-scale continuous production, and the like.

Description

technical field [0001] The invention relates to a coating method for glass, in particular to a method for rolling coating anti-ultraviolet coating glass on-line. Background technique [0002] Ultraviolet rays are electromagnetic waves ranging from 200 to 400nm. They are divided into short waves (200 to 280nm), medium waves (280 to 320nm) and long waves (320 to 400nm) according to their wavelengths. The shorter the wavelength of ultraviolet rays, the greater the damage to human skin. It is easy to cause diseases such as skin cancer, so how to effectively prevent ultraviolet radiation has attracted more and more attention. [0003] Ordinary glass itself does not have the characteristics of anti-ultraviolet rays. After long-term wind and rain, exposure to the sun, alternating dry and wet, and cold and hot changes, the glass surface will change color, crack, and even glass self-explosion. A large number of studies have shown that this aging phenomenon It is mainly caused by ult...
