Abstract

The invention discloses a flame-retardant sealing ring for motors of range hoods. The flame-retardant sealing ring is made from raw materials including nitrile rubber, zinc oxide, stearic acid, carbon black, white carbon black, sulphur powder, an accelerant CZ, an accelerant M, an accelerant TMTD, ETU-80, light magnesium oxide, pottery clay, chloroprene rubber adhesive, aluminum hydroxide, a silane coupling agent, zinc borate, antimonous oxide, modified flame retardant, dioctyl phthalate, carnauba wax, antiager 2246, antiager BZ and a processing agent WB-16. The flame-retardant sealing ring is good in high-temperature resistance and flame retardant performance, and meanwhile has the advantages of oil resistance, no halogen, low toxicity and environment friendliness.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a flame-retardant sealing ring for range hood motors. Background technique [0002] The range hood is an electrical appliance that purifies the kitchen environment. With the improvement of people's quality of life, the range hood has become an indispensable kitchen equipment for modern families. It is installed on the top of the kitchen stove, which can quickly take away the waste burned by the stove and the harmful oil fume produced during the cooking process, and discharge it outside, reduce pollution, purify the air, and have the safety guarantee function of anti-virus and explosion-proof. Due to the phenomenon of high-temperature flow and low-temperature cracking of the sealing ring used for the existing range hood motor, and poor high-temperature flame retardancy, it is easy to age, crack and even burn in the environment of high-temperature animal and vegetable oil...
