example 1

[0017] Example one: the present invention adopts the production technique of the resin lens of special molding, comprises the following steps:

[0018] S1: First prepare the raw materials according to a certain proportion. The weight components of the raw materials are: UV absorber: 6 parts, nano-scale alumina after high temperature annealing: 11 parts, dimethyl isophthalate: 17 parts, dibutyl phosphate : 10 parts, methyl styrene: 8 parts, polycarbonate: 38 parts, catalyst: 4 parts, hardener: 6 parts;

[0019] S2: First add methyl styrene, dimethyl isophthalate, alumina and polycarbonate into the reactor in sequence, and stir fully for 2.5-3.5 hours under the protection of nitrogen, try to keep the constant temperature state, after the stirring is completed After standing still for 0.5-1.5 hours, then gradually add catalyst, hardener, dibutyl phosphate and ultraviolet absorber into the reactor, continue to stir at constant temperature under nitrogen protection for 1-3 hours to...

Abstract

The invention discloses a high-definition lens and a preparation method thereof. The high-definition lens contains the following raw material components in parts by weight: 1-10 parts of an ultraviolet light absorber, 8-20 parts of high-temperature-annealed nano-scale aluminum oxide, 10-25 parts of dimethyl isophthalate, 5-18 parts of dibutyl phosphate, 1-9 parts of methyl styrene, 30-50 parts ofpolycarbonate, 1-8 parts of a catalyst and 3-7 parts of a hardening agent. The preparation method is simple in process; by virtue of the cooperation between aluminum oxide and a polycarbonate component, high light transmittance of a glasses lens is effectively maintained, and the eyesight is clear and natural, so that the prepared lens is good in light transmittance and strong in antifogging property, the ageing resistance of a resin lens is improved, the lens is ultra-strong in impact resistance and unlikely to dim, meanwhile, the entrance of ultraviolet can be inhibited, the radiation can beprevented, and the blood circulation can be promoted.

Description

technical field [0001] The invention relates to a high-definition lens and a manufacturing method thereof, belonging to the technical field of glasses production. Background technique [0002] In real life, when wearing glasses or during special shooting, we find that blurred vision or images will appear in some environments. Scientific research has found that this is due to the relatively long wavelength of infrared rays in the environment. The refractive index is smaller than that of visible light, and the imaging position of infrared rays is later than that of visible light when imaging through the same lens. Therefore, an excessive proportion of infrared light imaging will affect the clarity of the final effect of the picture. [0003] Therefore, in the process of lens production, the technology of processing red light, namely (Clear red and polarized light) is referred to as CRP technology; in the infrared optical system, some commonly used components have different re...
