Abstract

The invention relates to a scratch-resistant lens and a production process thereof. The production process comprises the following steps: mixing fluorine-containing dimethyl carbonate, allyl alcohol, calcium methoxide and a filler for reaction, performing dealcoholization, replacement reaction and distillation to obtain modified allyl diglycol carbonate, then adding diisopropyl peroxydicarbonate, and carrying out polymerization reaction and curing to obtain the scratch-resistant lens. The preparation method of the filler comprises the following steps: firstly, reacting boron phosphate with ammonia gas to prepare phosphorus-doped hexagonal boron nitride; then adding phosphorus-doped hexagonal boron nitride into a cerium chloride aqueous solution, performing stirring and heating, dropwise adding a sodium carbonate aqueous solution, and stirring for reaction to obtain a nano cerium oxide-phosphorus-doped hexagonal boron nitride compound; and finally, carrying out modification treatment on the nano cerium oxide-phosphorus- doped hexagonal boron nitride compound through gamma-methacryloxypropyltrimethoxysilane to obtain the required product. The lens is good in scratch resistance and high in light transmittance.

Description

technical field [0001] The invention belongs to the technical field of lens manufacturing, and relates to a scratch-resistant lens and a production process thereof. Background technique [0002] In recent years, the demand for optical resin lenses in the glasses market at home and abroad has been increasing. Compared with glass lenses, resin lenses have the advantages of light weight, strong impact resistance, stable optical performance, and easy processing. However, resin lenses are made of organic polymer materials, with low surface hardness, poor wear resistance, poorer chemical resistance than glass, and easy scratches on the surface, often requiring hard coating, multi-layer anti-reflection coating and top film to improve performance. [0003] Therefore, the quality of high-quality lenses is not only determined by the lens material, but its surface coating also plays a vital role. The film layer on the surface of the lens is also constantly being updated. Now the domes...
