Composite refraction ink glass panel used for vehicle front windscreen and manufacturing method of composite refraction ink glass panel

Abstract

The invention discloses a composite refraction ink glass panel used for a vehicle front windscreen and a manufacturing method of the composite refraction ink glass panel. Glass body constituents of the panel are composed of silicon dioxide and potassium oxide. A high refraction layer composed of silicon tetrafluoride, cerium oxide and germanium tetrachloride is fixed to the convex face of a glassbody, and a low refraction layer composed of silicon tetrafluoride, zirconium oxide, titanium oxide and boron oxide is fixed to the concave face. An ink screen is cured inside, and the basic structureof the ink screen comprises a high-transmittance ITO film and a balanced ITO film which are cured through indium oxide and stannic oxide according to different mass ratios, transparent oily liquid containing white particles with charges and transparent particle microcapsules with opposite charges suspends between the two films, the ink screen is provided with two electrostatic systems, one electrostatic system comprises transparent front and rear electrostatic substrates composed of the two ITO films, and the other electrostatic system comprises left and right electrostatic substrates composed of metal bars on the two sides. The composite refraction ink glass panel refracts part of external light and is good in inward vision light transmission, adjustable in transparency and wide in application range.

Description

technical field [0001] The invention relates to the field of glass products, in particular to a composite refraction ink glass panel for a front screen and a manufacturing method thereof. Background technique [0002] The ink screen is composed of two substrates, coated with an electronic ink composed of countless tiny transparent particles. In a conventional ink screen, these electronic ink particles are sealed in the internal liquid microparticles by many black and white particles with positive and negative charges. Formed in the capsule, charged particles of different colors will move in different directions due to different applied electric fields, showing a black or white effect on the surface of the display. However, the conventional ink screen is only black and white, opaque, and obviously cannot be used for the front windshield of a car. [0003] With the development of the times, the degree of specialization of glass is getting higher and higher. For the sake of pr...

However, conventional ink screens are only black and white, opaque, and obviously cannot be used for car front windshields

[0003] With the development of the times, the degree of specialization of glass is getting higher and higher. For the sake of privacy, almost all car users need to use refraction type tempered glass (can be seen from the inside but cannot be seen from the outside). The refractive glass in the technology is coated glass on the outer surface. Regardless of the method of coating, the coating is metal oxide or pure metal. This is to use the optical absorption spectrum of metal or metal oxide to absorb light in a certain frequency range. However, we found that when the brightness inside the car is higher than that outside the car, the effect of this shielding will be greatly reduced; , pure metallic silver (refractive glass in the prior art is generally evaporated metal silver and other materials) is also easily blackened by sulfur pollution in the air, so the reflective glass of conventional technology is easy to deform and change color, and has a short service life
