Example Embodiment

[0028] Example

[0029] The process of the embodiment adopts the combined curing method of ultraviolet light heating and curing. The products produced are tested and meet the standards, and some performances are better than those produced by the current heat curing method.

[0030] The light-curing molding process of this resin lens includes: raw material deployment, raw material pouring, UV curing, mold opening, mold closing, and post-curing of the lens, such as figure 1 .

[0031] Raw material deployment

[0032] The monomer raw material is divided into two parts: main material and auxiliary agent. The main material is mixed with acrylic acid monomers, and the auxiliary agents include functional modifiers, ultraviolet absorbers, internal release agents, initiators, and color pastes. The main materials and auxiliary agents are mixed in a certain proportion.

[0033] The main material is mixed with acrylic monomers, including at least one of monofunctional acrylate monomers...

Abstract

The invention provides a light curing forming process for a resin lens. The light curing forming process comprises the following steps of raw material blending, raw material pouring, ultraviolet light curing, mold making and postcuring; specifically, blended monomer raw materials are put into a special curing machine after raw material pouring, a to-be-cured mold are sequentially subjected to an IR preheating stage, a UV curing stage, a cooling stage and then discharging; after the mold receives light energy at the UV curing stage, monomers are polymerized into a solid state from the liquid state in the mold; and a preliminarily formed product obtained through mold making is fed into a postcuring furnace, and a finally formed product is obtained after curing. Light-heat combination curing is adopted for the light curing forming process for the resin lens, a forming cycle only needs several minutes, and the light curing forming process is a first creation in China and in the world. The light curing forming process for the resin lens is different from the current resin lens heat curing forming process of which a forming cycle needs twenty hours. The light curing forming process for the resin lens is capable of saving energy, protecting the environment, efficient, high in technological automation, simple and easy to learn. The finished product is more excellent in performance through detection.

Description

technical field [0001] The invention relates to a new molding process of resin lenses, in particular to a photocuring molding process of resin lenses. Background technique [0002] Glasses are closely related to people's normal life and are well known to the public. The development of the glasses industry has experienced several generations of exploration and innovation, and has made great progress. In the past two decades, the manufacturing process of resin lenses has been using heat curing process, and a molding cycle takes about 20 hours. [0003] At present, the domestic and international resin lens molding processes are all produced by thermal curing, which requires a long production cycle of about 20 hours, high power consumption, large number of molds, high pollution of waste gas and wastewater discharged from mold cleaning and curing furnace, and odor in the production workshop. Heavy, easy to cause dermatitis, respiratory infection, glasses pain. There is also a ...
