Abstract

The invention discloses PC anti-fog spectacle glasses and a preparation method thereof. The method includes following steps: weighing PC, 2-ethyl-2-oxazoline, 2-ethylhexyldiphenyl phosphate, polypropylene glycol, polyglycerol fatty acid ester, diphenyl sulphone, an ultraviolet absorbent, 3,4-dimethylbenzalsorbitol, tert-butyl peroxy-2-ethylhexanoate, PA6, an anti-oxidant, PA66, cumyl peroxyneodecanoate, DOP and dicumyl peroxide as raw materials, mixing the raw materials uniformly, performing an extrusion granulating process, performing solidification and an edge-deburring process, performing a film coating process, a cleaning process, a drying process and performing a test and package process. The spectacle glasses are 95-98% in light transmittance which is increased by 5-15% and is 1-3% in haze. A cantilever beam impact strength is 900-1000 J / m and a -30 DEG C notch impact strength is 18-20 kJ / m<2>. The spectacle glasses are 1.8-2.0 in a refractive index which is increased by 0.2-0.5. A bending strength is 125-130 MPa.

Description

Technical field [0001] The application belongs to the field of resin lens preparation technology, and in particular relates to a PC anti-fog spectacle lens and a preparation method thereof. Background technique [0002] Resin is a kind of hydrocarbon secretion from various plants, especially coniferous plants. It is valued because of its special chemical structure and can be used as latex paint and glue. It is a mixture of multiple polymer compounds, so it has different melting points. Resins can be divided into natural resins and synthetic resins. There are many types of resins, which are widely used in people's light industry and heavy industry, and can often be seen in daily life, such as plastics, resin glasses, coatings, etc. Resin lens is a lens that is chemically processed and polished with resin as the raw material. The optical resin lens is an organic material with a polymer chain structure inside, which is connected to form a three-dimensional network structure. The...
