Embodiment 1

[0090] This example provides a UV-curable resin composition and the lens prepared therefrom. For the composition of the UV-curable resin composition, refer to Example 1 in Table 1. Mix the reagent and its listed weight parts evenly Finally, the resulting glue was first tested for glue performance, and the results are shown in Table 3.

[0091] Afterwards, the photocurable lens is prepared, and the specific implementation steps are as follows:

[0092] (1) Put the photocurable composition above into a vacuum oven at room temperature for vacuum defoaming (30min, <0.1torr).

[0093] (2) After the defoaming of the composition is completed, inject it into a transparent mold, close the mold with an apron or adhesive tape to form a mold body, and use ultraviolet light to perform an energy on the mold body in the transparent mold. A radiation curing step of 3 minutes allowed the mold to form a photocurable lens. After that, the manual punching machine was used to remove the mold, an...

Embodiment 2-5

[0095] The UV-curable resin composition provided by Examples 2-5 and the lens prepared thereof, the composition of the UV-curable resin composition is as shown in Example 2-5 in Table 1, using the same After mixing evenly and performing the performance test of the glue solution, the mold body was formed by injection molding, and the lens was cured to obtain the lens, and the following lens evaluation items were carried out, and the results are shown in Table 3.

Abstract

The invention belongs to the technical field of resin optical device preparation, and in particular relates to a photocurable resin composition and an optical device prepared therefrom. The composition includes the following components in parts by weight: 40-70 parts of acrylate monomers, 5-15 parts of multi-reaction group crosslinking agents, 15-30 parts of epoxy compounds, 0.1-5 parts of free radical initiators, 0.1-5 parts of cationic photoinitiator. Using the resin composition provided by the present invention to carry out the photocuring step to prepare optical devices not only has a simple process, is environmentally friendly, has high production efficiency, can reduce process costs, and greatly shortens the process time and the amount of molds required. The prepared optical device (lens) not only has high hardness, impact resistance and chemical resistance, but also has better light penetration, high brightness, high refractive index, and low stress lines, and can be applied to lenses, optical components, etc.

Description

technical field [0001] The invention belongs to the technical field of resin optical device preparation, and in particular relates to a photocurable resin composition and an optical device prepared therefrom. Background technique [0002] Lenses are used in everything from spectacle lenses used by the general public to high-precision optical drive read heads or optical lenses used in cameras. The traditional glass lens manufacturing process is made by optical grinding or precision cutting with diamond tools. Not only is the production difficult, the yield rate is low, time-consuming and labor-intensive, and the cost is high. When worn as glasses, the glass lens is easily damaged and cause harm. Therefore, the optical industry has developed optical molding processing technology to produce resin lenses to meet the huge market demand. [0003] Common resin lenses include thermoplastic resin lenses (such as polycarbonate (PC) lenses, plexiglass (PMMA) resin lenses), etc., ther...
