[Industrial Field of Application] The present invention relates to eyeglass frames made of plastic, and more specifically, the present invention relates to eyeglass frames made of plastic, and more specifically, a thermosetting epoxy resin as a main ingredient, an acid anhydride curing agent, and a polyether polyol flexibility imparting agent are mixed together. , relates to an eyeglass frame obtained by cast molding. [Background of the Invention] Materials for eyeglass frames include metals and organic polymer compounds. Organic polymer compounds are widely used because they are lighter than metals and can be made into a variety of colors. As organic polymer compounds, natural polymer compounds such as celluloid and acetate have been widely used. These are thermoplastic resins, which have problems with their strength, and to compensate for this, metal core rods are used in the temple parts. Among organic polymer compounds, thermosetting resins have excellent strength, so they do not require a metal core, are suitable for weight reduction, and can be made in a wide variety of colors. The present invention relates to eyeglass frames made of thermoset plastic. [Prior art and problems] Eyeglass frames made of cellulose derivatives such as celluloid and acetate use plasticizers, so they become brittle over time, have insufficient mechanical strength, and have low heat deformation temperatures. is low, so
A metal core rod is used in the temple. These problems are caused because the cellulose derivative is a linear thermoplastic resin. These problems are solved by using a thermosetting resin, but this is due to the crosslinking reaction of the resin. Eyeglass frames made of epoxy resin, which is a thermosetting resin, have largely solved the above problems, but are still insufficient and can sometimes cause deformation (Gerard Hampel, Japanese Patent Publication No. 49-24687).
The main reason for this is thought to be that the heat distortion temperature is 80°C or less. Even when an epoxy resin is used, a cured product using an amine compound as a curing agent is substantially pale yellow and lacks transparency, making color control difficult.
Furthermore, due to the problem of weather resistance, yellowing occurs over time during daily use. Particularly when dyes are used for coloring, color fading occurs frequently. Furthermore, since amine compounds are highly irritating to the skin, they may cause skin damage at the contact area between the eyeglass frame and the skin. This also applies to production processes, which can cause skin and respiratory disorders for workers. [Objective and Structure of the Invention] As a result of intensive studies to improve the drawbacks of the above-mentioned conventional methods, the applicant has developed a method that uses epoxy resin as the main ingredient, is non-toxic as a curing agent, and has a structure that can exhibit high mechanical strength. By selecting an acid anhydride compound and designing the molecule of the flexibility imparting agent to improve flexibility and maintain a high heat distortion temperature, it has excellent transparency and weather resistance, and is resistant to colored dyes. We have discovered that it is possible to produce plastic eyeglass frames that have excellent weather resistance and do not lose their shape, and have completed the present invention. That is, the gist of the present invention is to use bisphenol A type diglycidyl ether as the main ingredient, and to use a liquid cycloaliphatic acid anhydride (specifically, 3-methyl-Δ 4 -tetrahydrophthalanhydride) as the curing agent. acid, 4-methyl-Δ 4 -tetrahydrophthalic anhydride, 3-methylhexahydrophthalic anhydride, 4-
methylhexahydrophthalic anhydride, meternazic anhydride, methylbutenyltetrahydrophthalic anhydride, etc.), and further, by using one type of polyether polyol or a combination of two or more types as a flexibility imparting agent, It has excellent transparency and weather resistance, as well as the weather resistance of colored dyes, and does not cause skin damage.Furthermore, it has a well-balanced mechanical strength, flexibility, and heat distortion temperature, so it does not lose its shape. The invention consists in a plastic eyeglass frame having a In the present invention, the epoxy resin as the main component is bisphenol A type diglycidyl ether with a molecular weight of 344 to 488. As a general formula, In the present invention, a cyclic aliphatic acid anhydride is used as a curing agent for the epoxy resin that is the main ingredient. 3
It is preferable to have an alkyl group at the position or the 4-position, and if necessary at the 3- or 4-position, and it is further preferable to be liquid at room temperature. Further, since it has a liquid state at room temperature, it may be a mixture of cyclic aliphatic acid anhydrides having alkyl groups at the 3rd and 4th positions.
