Problems solved by technology

[0004] Common arc breakers on the market are made of PVC (polyvinyl chloride). However, PVC is easily decomposed when it is burned and produces a large amount of toxic gases such as hydrogen chloride and dioxin. Corrosion of the metal parts of the circuit breaker, activation of the original stable heavy metal components such as lead, cadmium, etc. in the circuit breaker, which in turn leads to heavy metal pollution in the living environment

Abstract

The invention discloses a flame-retardant TPE arc-insulating sheet and a preparation method thereof. The flame-retardant TPE arc-insulating sheet replaces an arc-insulating sheet prepared from a PVC material in the invention. Compared with the arc-insulating sheet prepared from the PVC material, the flame-retardant TPE arc-insulating sheet provided by the invention reduces generation of toxic gasand heavy metal pollution. According to a technical scheme in the invention, the flame-retardant TPE arc-insulating sheet comprises, by mass, 15-20 parts of SEBS, 15-20 parts of white oil, 15-20 partsof PP, 20-25 parts of PE, 0.2-0.5 part of a hindered phenolic antioxidant, 0.2-0.5 part of phosphite, 0.2-0.5 part of stearic acid, 22- 28 parts of a flame retardant, 0.2-0.6 part of silicate and 0.2-0.6 part of shell powder. The TPE arc-insulating sheet provided by the invention has good flame retardant performance.

Description

technical field [0001] The invention relates to an arc breaker, in particular to a flame-retardant TPE arc breaker and a preparation method thereof. Background technique [0002] The low-voltage circuit breaker is a commonly used power distribution appliance, which is widely used in various electric power projects. It is responsible for power distribution and protection in the low-voltage power distribution system. Its operational performance is crucial to the security and stability of the power grid. When a fault occurs in the system, the circuit breaker quickly cuts off the faulty part of the system, or cuts off the entire power supply, so as to prevent the fault from expanding and avoid huge economic losses and casualties. [0003] The existing low-voltage circuit breaker will be equipped with an arc extinguishing device inside. The arc extinguishing device is an arc extinguishing chamber composed of multiple arc extinguishing plates. When the circuit breaker trips, the ...
