Description

technical field [0001] The invention relates to the field of organic glass materials, in particular to an organic glass material and a preparation method thereof. Background technique [0002] Polymethyl methacrylate (PMMA), commonly known as plexiglass, has excellent light transmission properties, can pass through more than 92% of sunlight, and 73.5% of ultraviolet rays; and has high mechanical strength and certain heat and cold resistance , Corrosion resistance, good insulation performance, stable size, easy to form, but the texture is brittle, the surface hardness is not enough, and it is easy to rub hair. It is often used to make transparent structural parts with certain strength, such as oil cups, car lights, instrument parts, optical lenses and decorative gifts. [0003] Plexiglass is a chemical polymer material that is not harmful to the human body. Usually, some auxiliary materials and additives are added to polymethyl methacrylate to improve and optimize its perfor...
