Abstract

The invention discloses a silica gel spectacle frame and a preparation technology thereof. The preparation technology comprises the steps of mixing raw silica gel with filler, continuing to add a vulcanizing agent, a catalyst and a chain extender and evenly stirring to obtain a pre-injection sizing material; injecting the pre-injection sizing material into moulds of spectacle legs, the spectacle frame and connection parts, vulcanizing the sizing material and release pressure to normal pressure after vulcanizing; curing, cooling and demoulding obtained prefabricated parts; connecting and assembling silica gel finished products of the obtained spectacle legs, the spectacle frame and the connection parts through metal screws and nuts to obtain the silica gel spectacle frame. The silica gel spectacle frame prepared by the preparation technology disclosed by the invention has extremely high biocompatibility and skin comfort degree, convenience in wearing and easiness in maintenance.

Description

technical field [0001] The invention relates to the field of spectacles, in particular to a silica gel spectacle frame and a preparation process thereof. Background technique [0002] The spectacle frame is an important part of the glasses. It can not only support the spectacle lenses, but also have a beautiful appearance. The materials used to make spectacle frames mainly include metal, plastic, and natural materials. With the continuous improvement of living standards, the industry standards for spectacles are constantly being revised, which requires not only durable spectacle frames, but also light, stable, safe, reliable, non-toxic, and skin-friendly materials for spectacle frames. Especially for people with sensitive skin and children, the material of spectacle frames is more required to be mild to the touch, safe and non-irritating. Therefore, it is necessary to carry out new exploration and research on spectacle frame materials. [0003] According to its properties...
