Problems solved by technology

[0002] In order to ensure the quality of technical resin lenses, the method used in the production of resin lenses in the prior art, in addition to the lens being cured once, must be cured again. The production method of this resin lens has been recognized as a classic method, otherwise, it cannot be produced. qualified product
However, the secondary curing of the lens not only increases the production process, time and production cost, but also the surface of the lens will be scratched during the transportation process, increasing the rate of defective products

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] see figure 1 As shown, the present invention avoids secondary curing resin lens and its preparation method, specifically as follows:

[0023] A. Process flow

[0024] Original process:

[0025] Lens primary curing → secondary curing → HMC (hardened and UV-resistant coating) → packaging

[0026] change to:

[0027] One-time curing of the lens → HMC (hardening and anti-ultraviolet coating) → packaging

[0028] The function of secondary curing of the lens in the prior art is to further react inside the lens (the temperature of the secondary curing is 105 degrees, 1 hour), and further eliminate the stress inside the lens.

[0029] The present invention combines the HMC hardening step of the lens substrate, and the hardening temperature is 110 degrees for 2 hours in an oven. It not only completes the task of hardening the lens substrate, but also plays a role i...

Abstract

The invention discloses resin glasses free of secondary curing and a preparation method thereof, and relates to the technical field of glasses. The preparation method comprises the following steps that a primary curing of the glasses is carried out, HMC (hardening and anti-ultraviolet coating) is conducted, and a packaging process step. According to the resin glasses free of secondary curing and the preparation method thereof, process design is scientific, reasonable and novel, a process step of secondary curing can be omitted boldly in the production process of substrate, the production process, time and production cost are reduced, the production efficiency is improved, the qualified rate is increased, and good internal quality, and stable and reliable performance of products are guaranteed.

Description

technical field [0001] The invention relates to the technical field of eyeglasses, in particular to secondary curing-free resin lenses. technical background [0002] In order to ensure the quality of technical resin lenses, the method used in the production of resin lenses in the prior art, in addition to the lens being cured once, must be cured again. The production method of this resin lens has been recognized as a classic method, otherwise, it cannot be produced. Qualified product. However, the secondary curing of the lens not only increases the production process, time and production cost, but also the surface of the lens will be scratched during the transportation process, increasing the rate of defective products. Contents of the invention [0003] In order to solve the above-mentioned problems in lens production, the purpose of the present invention is to provide a secondary curing resin lens and its preparation method to solve it. [0004] Above-mentioned technic...
