Anti-fall fogging prevention glass lens

Abstract

The invention provides an anti-fall fogging prevention glass lens, and the lens is characterized in that the lens comprises an external glass lens, an internal glass lens, and supporting bars; the cross section of each supporting bar is shaped like L, and the supporting bars are located at the periphery of the inner wall of the external glass lens; the internal glass lens is put on the supporting bars; the external glass lens, the internal glass lens and the supporting bars form a closed vacuum layer through enclosing; the external surface of the external glass lens is provided with a fogging prevention coating layer; the fogging prevention coating layer comprises the following components by weight: 30-50 parts of polyvinylidene fluoride-acrylate grafted maleic anhydride; 10-25 parts of aqueous fluoro-silicone emulsion; 5-12 parts of inorganic nanoparticle sol; 1.5-2.5 parts of Texanol; 0.5-3 parts of alkaline silicate; 1-8 parts of propylene glycol; 20-40 parts of water. The lens provided by the invention is resistant to fall and impact, solves a problem that water mist is liable to condense on the surface of a lens when the products of the type are used during low temperature or in rain or snow days, achieves the fogging prevention effect, and is good in use effect.

Description

technical field [0001] The invention relates to a glass lens, in particular to an anti-drop and anti-fogging glass lens. Background technique [0002] In China, the generalization and popularization of various middle and high-end mobile phone and tablet users, especially with the rapid development of global touch screen technology, makes the demand for screen glass lenses (also called glass sheets) is increasing. However, when the temperature is low or when using such products in rainy and snowy weather, water mist condensation is likely to occur on the surface of the glass lens, hindering the use of the user. So it is particularly important and urgent to develop a kind of anti-drop and anti-fogging glass eyeglass glass eyeglass. Contents of the invention [0003] In order to solve the above existing problems, the object of the present invention is to provide an anti-drop and anti-fogging glass lens. The anti-fall and anti-fogging glass lens is anti-fall and impact-resis...
