Abstract

The invention discloses an epoxy resin glass fiber composite isolation protection material which is prepared from the following raw materials in parts by weight: 100-150 parts of epoxy resin, 10-15 parts of glass fiber, 10-20 parts of a polyaniline-silicon carbide compound, 35-50 parts of an inorganic flame retardant, 5-10 parts of nano calcium carbonate, 20-55 parts of a rare earth coupling agent and 5-10 parts of a dispersing agent. The inorganic flame retardant is composed of magnesium hydroxide and calcium hydroxide. The invention also discloses an application of the epoxy resin glass fiber composite isolation protection material in isolation protection of a relay protection wiring terminal. The epoxy resin glass fiber composite isolation protection material has good moisture resistance, flame retardance and wave-absorbing anti-interference performance, isolation protection can be better carried out on a wiring terminal, and the safety is improved.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to an epoxy resin glass fiber composite isolation protection material and its application in battery isolation protection. Background technique [0002] During the reconstruction of the relay protection project, equipment maintenance and protection software upgrade, the staff must implement secondary safety measures to repair the running equipment and terminal blocks in the same screen of the panel cabinet that has been powered off (the terminal block consists of multiple models of UDK4 or URTK). / S or UK3N Phoenix terminal combination) for isolation, in order to ensure the smooth progress of the work. However, the space on the same screen is relatively small. If the isolation effect is not good, the staff are often easy to touch the live terminals during the work process, resulting in electric shock to the person or malfunction of the equipment and...
