Abstract

The invention belongs to the technical field of vision window glass, and particularly discloses a preparation method of wear-resistant and high-temperature-resistant vision window glass and the prepared vision window glass, wherein the preparation method comprises the following steps: weighing a nanosheet layer Ti3C2Tx MXene, carrying out vacuum heat treatment to obtain a TiO2 / Ti3C2Tx MXene compound, adding the TiO2 / Ti3C2Tx MXene compound into ethanol, and carrying out ultrasonic stripping to form a colloidal solution; and dissolving gamma-aminopropyltriethoxysilane in the colloidal solution, adding nano silicon dioxide aerogel in a stirring state, carrying out ultrasonic dispersion to prepare a silicon dioxide aerogel / TiO2 / Ti3C2Tx MXene nano composite colloidal solution, adding methyl methacrylate and alpha-methyl styrene to prepare a prepolymer, and further preparing the vision window glass. The prepared vision window glass has a nanoscale particle skeleton, is extremely narrow in diameter range distribution, has good rigidity and high-temperature resistance and heat insulation, is excellent in scratch resistance and high in impact strength, and lays a foundation for application to 3D printer vision window glass.

Description

technical field [0001] The invention belongs to the technical field of window glass products, and in particular relates to a method for preparing a wear-resistant and high-temperature resistant window glass and the prepared window glass. Background technique [0002] The viewing window is a common chemical equipment accessory, and it is a necessary device for observing various chemical processes. It is widely used in chemical equipment. The window is generally composed of a transparent part and a sealing part, and the transparent part can be made of ordinary inorganic glass or organic glass. In a 3D printer, the window glass is one of the important components. In order to facilitate the observation of the process in the printer and maintain the required working temperature in the printing chamber, it is necessary for the window glass to have excellent light transmittance, heat resistance, heat insulation and good mechanical properties. [0003] Polymethyl methacrylate (PMM...
