Embodiment 1

[0021] Embodiment 1: the preparation of raw material mixture

[0022] One day before the curing reaction, mix 490 parts of KT60A, 15 parts of UV31, 0.7 parts of UB67, 0.7 parts of B75, 0.5 parts of R51, 420 parts of KT60B, 90 parts of KT60C and 1.2 parts of DC at room temperature to make raw materials Mixture, the above raw materials are all products from KOC SOLUTION CO., CTD.

[0023] After the raw materials are mixed, they are heated under stirring in a stirring pot, and the viscosity is tested after the temperature reaches 40°C. After the viscosity reaches 60 mpa.s, use a cold water bath to quickly cool down to 25°C while stirring, and store for later use.

Embodiment 2

[0024] Embodiment 2: the preparation of lens mold

[0025] Assemble the lens upper mold, lower mold and spacer together, put the rubber ring on the outside, pay attention to align the injection hole of the rubber ring with the gap of the spacer to facilitate filling.

Embodiment 3

[0026] Example 3: Curing

[0027] After pouring the liquid stock mixture into the prepared mold, heat cure using the cycle shown in the table below

[0028] temperature °C 20 35 50 60 90 130 130 70 running time h time h 2 5 7 1 2 1.5 2 1 21.5

[0029] After the curing is completed, after the mold drops to room temperature, the rubber ring is removed, and the mold is separated to obtain the lens.

Abstract

The invention provides a production method of a spectacle lens. The production method comprises the following steps: (a) preparing a raw material mixture; (b) injecting the raw material mixture into a mold, and performing the primary curing; (c) coating the lens, wherein the raw material mixture comprises the following components in parts by weight: 490 parts of KT60A, 15 parts of UV31, 0.7 part of UB67, 0.7 part of B75, 0.5 part of R51, 420 parts of KT60B, 90 parts of KT60C and 1.2 parts of DC. The produced spectacle lens is firm, the optical performance of the produced spectacle lens is high, the impact resistance of the lens is high, and the spectacle lens is safe and reliable to wear.

Description

technical field [0001] The invention belongs to the field of optics, and in particular relates to a method for manufacturing spectacle lenses. Background technique [0002] In the current technology of making spectacle lenses, in order to achieve high-definition effects, it is necessary to make a certain compromise on the strength, resulting in the production of spectacle lenses that are fragile and easy to break, causing safety hazards to the wearer. Contents of the invention [0003] The invention adopts a novel production method, and the produced spectacle lenses have high impact resistance, and at the same time, the surface is firm and wear-resistant, easy to clean, high in light transmittance, and clearer in vision. The present invention adopts technical scheme as follows: [0004] A method for making spectacle lenses, comprising the steps of: [0005] a) Prepare raw material mixture; [0006] b) Inject the raw material mixture into the mold for primary curing; ...
