Description
Technical Field
The invention belongs to the technical field of optical lenses, and particularly relates to a raw material formula of a high-refractive-index resin lens.
Background
The research and development of the current materials for eyeglass lenses using synthetic resins having excellent optical characteristics as lens materials in addition to inorganic glass are being developed, and there is a tendency to gradually replace the conventional lens materials. Compared with an inorganic glass lens, the resin lens has the characteristics that: light weight, high transparency, large lens size, impact resistance, easy processing and molding, dyeability and the like. Resin sheets are in the priority position in the competition of the eyeglass market. It is reported that the optical resin lens accounts for 65% in the united states and about 55% in japan in 1988. Recently, about 85% to 90% of 3200 ten thousand people wearing spectacles in Japan have selected resin lenses. The first synthetic resin optical lens was poly (allyl diglycol carbonate) developed by PPG, usa in 1942, which is a thermosetting synthetic resin with a trade name of CR-39 and has excellent cutting and polishing properties, heat resistance and chemical resistance. The specific gravity is 1.32, which is about half lighter than the specific gravity of 2.58 of inorganic optical glass, and the dyeing process is also simpler. CR-39 was developed by the American Columbia research institute, and is also known as Columbia resin, and has a dominant position in the resin lens market.
However, optical resin materials widely used in the market at present, such as polymethyl methacrylate (PMMA), CR-39, etc., have a low refractive index (nD < 1.50), and the PS with the highest refractive index of the conventional optical resin only reaches nD 1.590, and the overall performance is not ideal, which limits the application range of the materials. In addition to the requirement of good optical performance, the lens material is required to be light and thin according to the fashion style of the eyeglass market, which has become the main direction in the research and development of the current resin lens. Therefore, the synthesis of new high-performance transparent resin is an inevitable trend in the development of optical plastics, and research on the preparation of high-refractive index and high-performance transparent optical resin has become a hot spot.
