The preparation method has a very good popularizing and applying value.

Description

technical field [0001] The invention belongs to the technical field of organic glass processing and manufacturing, and in particular relates to a preparation method of a toughening filler for organic glass. Background technique [0002] Polymethyl methacrylate, commonly known as plexiglass, has excellent optical properties, weather resistance and chemical corrosion resistance, good electrical insulation and biocompatibility, easy to process and shape, and high mechanical strength. It is widely used in aviation, navigation, construction and daily life etc. In order to ensure the use quality of plexiglass in different corresponding fields, it is often necessary to enhance and improve one or more of its characteristics, such as toughening and enhancing temperature resistance. There are many ways to toughen plexiglass, such as adding inorganic fillers to improve it. Although some results have been achieved, the improvement effect still needs to be further improved.
