Flame-retardation sealing ring

Abstract

The invention discloses a flame-retardation sealing ring. The flame-retardation sealing ring comprises the following raw materials in parts by weight: 25-32 parts of fluorubber, 18-27 parts of chloroprene rubber, 13-18 parts of phenolic resin, 17-28 parts of m-p-cresol, 2-5 parts of a fire retardant, 3-5 parts of an activator, 3-7 parts of expandable graphite, 2-5 parts of a charing agent, 3-4 parts of calcium palmitate, 7-13 parts of an auxiliary agent, and 10-17 parts of a filling material. The flame-retardation sealing ring has the advantages that the excellent sealing is kept, the flame retardation performance of the sealing ring is obviously increased, the flame-retardation sealing ring has good heat resistance and flame retardation effects in operating electrical equipment, fire hazard due to overtemperature is avoided, the processing cost is low, and a processing method is simple.

Description

technical field [0001] The invention relates to a sealing ring, in particular to a flame-retardant sealing ring. Background technique [0002] In order to ensure the stable operation of electrical equipment, sealing rings need to be used around the connecting wires extending from the surface of the electrical equipment to prevent dust from entering the electrical equipment, affecting heat dissipation, and further affecting the stable operation of electrical equipment. However, the electrical equipment itself contains With a large number of components, individual components generate high heat. Long-term heat radiation will cause deformation or even burning of the sealing ring, which will further affect the operation of the components. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a flame retardant sealing ring with good flame retardant effect. [0004] In order to solve the above-mentioned technical problems, t...
