Abstract

The invention discloses a washing machine door special-purpose sealing ring. The sealing ring comprises base rubber, a filler and additives. The base rubber comprises an ethylene propylene diene monomer and silica gel compound rubber. The other components comprise white carbon, talcum powder, StronWi TM, high flash point paraffin oil, diethylene glycol, a silane coupling agent, zinc oxide, a mildewproof agent, paraffin wax, black master batches, titanium dioxide, an antiager, an accelerator and a vulcanizing agent. Through combination of the base rubber containing the ethylene propylene diene monomer and silica gel compound rubber and the fillers and additives, the ethylene propylene diene monomer sealing ring has good low / high temperature resistance and aging resistance. Through use of physical inertia of the silica gel compound rubber, smell friendliness of the sealing ring is improved. The sealing ring has the advantages of fine feeling, excellent hot aging resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of rubber composite materials, in particular to a special sealing ring for washing machine doors. Background technique [0002] The choice of sealing ring material is of great significance to its sealing performance and service life. The performance of the formula material directly affects the performance of the sealing ring. At present, the sealing rings for washing machine doors are made of EPDM rubber sealing rings, EPDM The rubber sealing ring has good weather resistance, ozone resistance, water resistance and chemical resistance, but has the following disadvantages: the EPDM rubber sealing ring has poor hand feeling and strong smell, especially for household appliances washing machines. The user brings certain negative effects, and the heat aging resistance of the product is not good, which seriously affects the service life of the sealing ring. Contents of the invention [0003] The invention provid...
