Abstract

The invention discloses a preparation method of a glass fiber plate glue liquid special for a planetary gear. The method comprises the following steps: (1) mixing a curing agent, a curing accelerator and a solvent shown in the Claim 1, and performing stirring till the materials are dissolved to obtain a mixture A; (2) mixing the mixture A with a resin, and performing uniform stirring to obtain a mixture B; and (3) in a stirring condition, mixing the mixture B with an inorganic filling material, performing shearing at a speed of 2200-2800 rpm, and performing curing to obtain the glass fiber plate glue liquid special for a planetary gear. The glass fiber plate glue liquid is excellent in thermal resistance and chemical resistance and is reduced in environmental pollution. Through comparison with the prior art, a prepreg and a glass fiber plate further made from the glue liquid is higher in toughness.

Description

technical field [0001] The invention specifically relates to a preparation method of a special glass fiber board glue for a star wheel. Background technique [0002] The star wheel is a fixture used in various plane polishing processes such as glass, lenses, silicon wafers, and hard disks. It is also called polishing fixtures, polishing pads, etc.; the polishing process has been developed for many years and has become very mature. Computers and other popular electronic products are widely popularized, touch screens are developing rapidly, lens polishing is developing rapidly, and the raw material of the star wheel has changed from the original blue steel sheet to FR-4 fiberglass board. [0003] At present, the main material of the star wheel is FR-4 fiberglass board. With various characteristics, glass fiber board is the most suitable material for manufacturing star wheels in the market. Its advantages are, such as: wear resistance, easy processing and forming, processing T...
