Abstract

The invention relates to a binding agent for precision injection molding of an optical fiber ceramic ferrule. An injection molding binding agent used for the optical fiber ceramic ferrule is prepared from the following components: fully-refined paraffin wax, microcrystalline wax, EVA, epoxy resin, dicyandiamide and stearic acid. The injection molding binding agent integrates the advantages of a traditional thermoplastic system binding agent and a thermosetting system binding agent and avoids respective defects of the traditional thermoplastic system binding agent and thermosetting system binding agent. The binding agent has a thermoplastic property in mixing and injection molding processes, so that uniform mixing and injection die stamping can be realized on thermoplastic equipment; in a degreasing process, resin is cured under the action of high temperature, and the binding agent has the thermosetting property; a degreased blank is not softened and deformed so that the size precision and the shape retaining capability of the product are improved.

Description

technical field [0001] The invention relates to a binder for precision injection molding of optical fiber ceramic ferrules. Background technique [0002] Ceramic injection molding is a method of uniformly mixing ceramic powder with an organic binder, molding it with an injection molding machine, removing the binder by thermal degreasing or solvent degreasing, and finally sintering at high temperature to obtain the final product. Craft means. Ceramic powder injection molding technology has shown incomparably strong vitality in the manufacture of new products with high precision and high added value, such as ceramic ferrules for optical fiber connectors in optical fiber communications (outer diameter 1.25mm, inner hole only 125μm, length 10mm), Among them, the size of the inner hole is required to be 125μm~126μm, and the precision is required to reach 1μm, which can only be manufactured by injection molding technology at present. [0003] The optical fiber connector is to pr...
