Problems solved by technology

[0009] Considering factors such as price and performance, currently domestic mirror frames are mainly acetic acid sheet frames, but the disadvantage of this material is that it is easily corroded by ketone, vinegar, alkyl liquids, high-concentration acids and alkalis, and it is easy to shrink and deform.
Although the performance of epoxy resin material is extremely good, the one-time molding and polishing process of this material requires a lot of investment in equipment, so the cost is high, and it is only used by some imported high-end famous brand frames.

Abstract

The invention provides novel material epoxy resin spectacle arm wires, a novel material epoxy resin spectacle frame and a processing and forming method thereof. The material of the spectacle arm wires and the spectacle frame is prepared from an epoxy resin raw material, a diluents, a curing agent and a softener; the processing and forming technique of the spectacle arm wires and the spectacle frame comprises: preparing raw materials, preheating a mold, preparing glue, defoaming, filling mold, curing, cooling, demolding, polishing and assembling. The spectacle arm wires and the spectacle frame processed and formed by the method have the advantages that: the wear is comfort; the appearance is beautiful; the spectacle frame is firm and durable; and the like. The production cost is low and is acceptable for common consumers.

Description

Technical field [0001] The invention relates to the field of material processing, in particular to a method for processing an epoxy resin material into eyeglass legs and eyeglass frames. Background technique [0002] With the continuous improvement of living standards, glasses can not only correct eyesight for people, but also become a kind of decoration. While pursuing comfort, the requirements for the appearance of products are also getting higher and higher. Frame materials currently on the market generally include metallic materials and non-metallic materials. Frames made of ordinary metal materials are relatively heavy, and long-term wear will compress the bridge of the nose and cause discomfort; and metal frames generally require electroplating, and the electroplating layer is likely to cause skin allergies. High-grade metal frames, such as titanium frames, are expensive, although they are made of fine materials. [0003] Non-metal frame materials include natural materials ...
