Abstract

The invention discloses a high temperature-resistant transparent glass fiber insulating board and a preparation method thereof. The scheme uses epoxy resin as the main material, benzoxazine resin and flame retardant prepolymer as auxiliary materials to prepare glue solution for the insulating board. The prepreg is obtained after dipping on the surface of the glass fiber cloth, and the prepreg is hot-pressed and compounded. The obtained insulating board not only has excellent high temperature resistance, but also has excellent flame retardant performance, and the surface is hydrophobic, which can effectively prevent the entry of water media. At the same time, due to the limited parameters of the flame retardant prepolymer, the crosslinking density of the glue is excellent, the water absorption rate is also greatly reduced, and the water resistance is more excellent. The invention discloses a high-temperature-resistant transparent glass fiber insulating board and a preparation method thereof. The process design is reasonable and the component distribution ratio is suitable. It can be widely used in various fields and has high practicability.

Description

technical field [0001] The invention relates to the technical field of insulating boards, in particular to a high temperature resistant transparent glass fiber insulating board and a preparation method thereof. Background technique [0002] Laminate is a kind of laminated product. Laminate is a whole made of two or more layers of resin-impregnated fibers or fabrics that are laminated and thermocompressed. Laminates can be processed into various insulation and structural parts. , With the development of the electrical industry, laminates have begun to be used in motors, transformers, high and low voltage electrical appliances, electrical instruments and electronic equipment, and glass cloth is one of the more widely used ones. [0003] The existing glass fiber insulation laminates on the market have average high temperature resistance, and poor mechanical properties and flame retardant properties, which bring great inconvenience to us in practical application. Therefore, in o...
