Abstract

The invention relates to the technical field of optical lens preparation, in particular to an anti-blue-ray mobile phone camera lens and a preparation process thereof. The anti-blue-ray mobile phone camera lens is prepared from the following raw materials in parts by weight: 95 to 100 parts of polycarbonate, 0.16 to 0.38 part of metal oxide, 0.14 to 0.28 part of nano powder, 0.25 to 0.45 part of modified mica powder, 0.025 to 0.032 part of diisopropyl peroxydicarbonate, 0.03 to 0.12 part of ultraviolet absorbent, 0.6 to 1.5 parts of blue light absorbent, 0.03 to 0.08 part of antistatic agent and 0.015 to 0.023 part of toner. The mobile phone camera lens prepared by the preparation method not only has good light transmission, but also has a good absorption effect on ultraviolet rays and blue light; in addition, the anti-blue-ray mobile phone camera lens has good anti-blue-ray performance, the blocking effect of the camera lens on harmful blue ray is effectively improved, and harm of ultraviolet light and blue ray to the body of a user is reduced; in addition, the camera lens also has excellent anti-ultraviolet capability so that the aging rate of the camera lens is effectively reduced, and the service life of the camera lens is prolonged.

Description

technical field [0001] The invention relates to the technical field of optical lens preparation, in particular to an anti-blue light mobile phone camera lens and a preparation process thereof. Background technique [0002] With the development of modern society, more and more electronic products such as mobile phones and computers have entered people's lives and work. More and more people like to travel, and use mobile phone cameras to record the beautiful scenery during the journey. However, when the mobile phone is in use, it is exposed to excessive blue light, purple light and ultraviolet light. The long-term exposure to these excessive high-energy rays will destroy the organic molecular structure of the cells in the eye, thereby causing damage to the human eye, the more common being macular degeneration, which is currently irreversible. It has caused considerable damage to people's health. [0003] Although the mobile phone camera lenses currently on the market have a...
