Embodiment Construction

[0050] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific diagrams.

[0051] refer to figure 1 , the manufacturing process of ultra-light resin lens, comprising the following steps:

[0052] The first step, the preparation of castable:

[0053] Raw material ratio: In the first step, polyisocyanate, polythiol 3-800, polythiol 3830-81, blue agent, catalyst DC, 1.60 raw material release agent, UV709 powder raw material that can block ultraviolet rays The mass percentage proportioning of is as follows:

[0054] Polyisocyanate: 50%-60%; Polymercaptan 3-800: 1%-3%; Polymercaptan 3830-81: 37%-47%; Blue agent: 0.02%-0.1%; DC: 0.1%-0.2%; Release agent: 0.05%-0.15%; UV709: 1%-2%.

[0055] The present invention can adopt the following mass percentage ratio: polyisocyanate: 50%; polythiol 3-800: 1.3%; polythiol 3830-81: 47%; b...

Abstract

The invention relates to the technical field of lens manufacturing, in particular to a manufacturing process for a resin lens. The manufacturing process for the ultralight resin lens comprises the following steps of (1) preparation of castable, (2) bubble removing, (3) casting, (4) curing, (5) mold manufacturing, (6) lens cleaning and (7) detection. Through the adoption of the technical scheme, the resin lens manufactured through the process has the obvious advantages of being low in specific gravity and the like.

Description

technical field [0001] The invention relates to the technical field of lens manufacturing, in particular to a resin lens manufacturing process. Background technique [0002] At present, ordinary optical resin lenses on the market are generally produced by a single ADC (CR-39) monomer, which has problems such as low impact resistance, low transmittance, and high specificity, and cannot meet people's increasing performance requirements for glasses. Especially people who wear glasses all the time in daily life are in urgent need of a lens with light specific gravity and reduced nasal pressure. Contents of the invention [0003] The object of the present invention is to provide a manufacturing process of ultra-light resin lenses to solve the above technical problems. [0004] The technical problem solved by the present invention can adopt following technical scheme to realize: [0005] The manufacturing process of the ultra-light resin lens is characterized in that it compri...
