Abstract

The invention discloses an antifogging toughened glass and a preparation method thereof. The preparation method comprises the following steps: cutting glass, toughening, cleaning, spray-coating, baking, and cleaning. A water-soluble acrylic resin is used as the antifogging agent of a film forming material according to a hydrophilic principle, and an antifogging film is formed on the surface of toughened glass by adopting a spray coating technology and a baking technology, and the film is hydrophilic, can reduce the contact angle of the surface of the glass to water, makes small water drops coagulating on the surface spread on the surface to form a film not tiny water drops, and reduces the diffuse reflection of light.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to an anti-fog tempered glass and a preparation method thereof. Background technique [0002] The interactive smart panel is an integrated device that integrates TV technology, computer technology, touch technology, and audio technology to realize human-computer interaction. It not only has the high-definition display function of traditional LCD TVs, but also can use It also has computing power, and can control the computer through touch technology to obtain a convenient human-computer interactive experience. [0003] In order to make the display screen of the interactive smart panel have a touch protection layer, and prevent personal and property damage caused by improper operation, a piece of tempered glass is added to the surface of the display screen during the design and production of the interactive smart panel. The currently used tempered glass does not have any anti-fog treat...
