Problems solved by technology

However, its wear resistance and impact resistance are poor, and thermosetting resin lenses are produced by casting, which requires a long thermosetting time (18-19 hours) and a large number of glass molds, so the production capacity is not easy to increase

Embodiment 1

[0052] Example 1 Preparation of photocurable lenses

[0053] Embodiment 1 is according to Table 1, after the reagent and its listed weight parts are mixed evenly, the obtained glue is firstly tested for glue performance, and the results are shown in Table 1.

[0054] After that, it is poured into the transparent glass mold, and the mold body is formed after the rubber ring or adhesive tape is used to close the mold. Next, the mold body in the light-transmitting mold is subjected to a photocuring step for 3 minutes by using ultraviolet light, so that the mold body is cured to form a lens. After that, the lens was demoulded and taken out, and after edging and cleaning, the following lens evaluation items were performed, and the results are shown in Table 2.

Embodiment 2 to 8

[0055] Examples 2 to 8 Preparation of photocurable lenses

[0056] Examples 2 to 8 are based on Table 1. After using the same method as Example 1 to mix evenly and perform a glue performance test, then injection mold to form a mold body, and perform the following lens evaluation items, the results are shown in Table 1 And shown in Table 2.

Abstract

The present invention relates to a photocurable lens and its manufacturing method, which uses a photocurable resin composition containing a specific proportion of various (meth)acrylate monomers and a photoinitiator to perform a photocuring step Afterwards, to make photocurable lenses. In this way, not only can the manufacturing cost be reduced and the manufacturing time greatly shortened, but also the obtained light-curable lens has higher hardness, better chemical resistance and impact resistance.

Description

technical field [0001] The present invention relates to a photocurable lens and its manufacturing method, in particular to a photocurable lens with shorter process time, higher hardness and better impact resistance and its manufacturing method. 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 optics 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, plexigla...
