Problems solved by technology

[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 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 a large number of components, and 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.

Abstract

The invention provides a flame retardant sealing ring used in electronic equipment. The flame retardant sealing ring is characterized by being prepared from the following components in parts by mass: 25 to 32 parts of fluororubber, 18 to 27 parts of chloroprene rubber, 13 to 18 parts of phenolic resin, 17 to 28 parts of cresol, 3 to 8 parts of polyhydroxy acrylic resin, 2 to 5 parts of a flame retardant, 3 to 5 parts of an activator, 3 to 7 parts of expansible graphite, 2 to 5 parts of a charring agent, 7 to 13 parts of an adjuvant and 10 to 17 parts of a filler. The flame retardant sealing ring can keep the excellent sealing property and obviously improve the flame retardant performance, so that the sealing ring has the good heat resistance and flame retardance effect in the operating electronic equipment, and a fire caused by extremely high temperature is avoided; furthermore, the treatment cost is low, and the treatment method is simple.

Description

technical field [0001] The invention belongs to the technical field of sealing, and in particular relates to a flame-retardant sealing ring used in electrical equipment. 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 a large number of components, and individual components generate high heat. Long-term heat radiation will cause deformation or even combustion of the sealing ring, which will further affect the operation of the components. [0003] Therefore, developing a sealing ring in order to solve the above problems is an urgent problem for those skilled in the art. Contents of the invention [0004] In order to so...
