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...
