Problems solved by technology

[0003] However, in the existing spectacle frame structures, most of the acetate fibers are directly heat-melted and then injection molded. However, due to the poor thermal conductivity of the acetate fibers, the melting efficiency is low, and it is also easy to cause some parts due to uneven heating. The material deteriorates and the quality is reduced. At the same time, the eyeglass frame made by the existing molding process is poor in aesthetics, and the surface is easy to scratch, which affects the long-term use. A new molding process needs to be proposed

Abstract

The invention discloses a composite material for manufacturing a spectacle frame by adopting acetate fibers and a forming process of the composite material. The forming process comprises the followingsteps of P2, baking; P3, hot melting; P4, mixing the materials; P5, injection molding; P6, polishing; P7, electroplating; and P8, carrying out post-treatment. According to the composite material formanufacturing the spectacle frame by adopting the acetate fibers and the forming process of the composite material, impurities can be effectively removed by cleaning and drying the raw material, and the composite material is compounded by adding barium sulfate after partially melting, so that the heat-conducting property can be effectively improved, sufficient melting is guaranteed, deteriorationis avoided, framework quality and structural strength are guaranteed, meanwhile, surface electroplating is carried out subsequently, surface hardness can be guaranteed, scratches are reduced, smoothness and attractiveness are improved, machining production and use are facilitated, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of spectacle frames, in particular to a composite material for spectacle frames made of acetate fiber and a molding process thereof. Background technique [0002] In today's social life, many people need to wear glasses, so it is necessary for technicians to produce different spectacle frames to install the lenses, which is convenient for people to use. Among them, the spectacle frames made of roughly selected fibers are light in texture and stable in structure. High, loved by people. [0003] However, in the existing spectacle frame structures, most of the acetate fibers are directly heat-melted and then injection molded. However, due to the poor thermal conductivity of the acetate fibers, the melting efficiency is low, and it is also easy to cause some parts due to uneven heating. The material deteriorates and the quality is reduced. At the same time, the eyeglass frame made by the existing molding proces...
